1插装阀概述二通插装阀是插装阀基本组件(阀芯、阀套、弹簧和密封圈)插到特别设计加工的阀体内,配以盖板、先导阀组成的一种多功能的复合阀。
因每个插装阀基本组件有且只有两个油口,故被称为二通插装阀,早期又称为逻辑阀。
1.1二通插装阀的特点二通插装阀具有下列特点:流通能力大,压力损失小,适用于大流量液压系统;主阀芯行程短,动作灵敏,响应快,冲击小;抗油污能力强,对油液过滤精度无严格要求;结构简单,维修方便,故障少,寿命长;插件具有一阀多能的特性,便于组成各种液压回路,工作稳定可靠;插件具有通用化、标准化、系列化程度很高的零件,可以组成集成化系统。
1.2二通插装阀的组成二通插装阀由插装元件、控制盖板、先导控制元件和插装块体四部分组成。
图1是二通插装阀的典型结构。
图1二通插装阀的典型结构控制盖板用以固定插装件,安装先导控制阀,内装棱阀、溢流阀等。
控制盖板内有控制油通道,配有一个或多个阻尼螺塞。
通常盖板有五个控制油孔:X、Y、Z1、Z2和中心孔a(见图2)。
由于盖板是按通用性来设计的,具体运用到某个控制油路上有的孔可能被堵住不用。
为防止将盖板装错,盖板上的定位孔,起标定盖板方位的作用。
另外,拆卸盖板之前就必须看清、记牢盖板的安装方法。
图2盖板控制油孔先导控制元件称作先导阀,是小通径的电磁换向阀。
块体是嵌入插装元件,安装控制盖板和其它控制阀、沟通主油路与控制油路的基础阀体。
插装元件由阀芯、阀套、弹簧以及密封件组成(图3)。
每只插件有两个连接主油路的通口,阀芯的正面称为A口;阀芯环侧面的称作B 口。
阀芯开启,A口和B口沟通;阀芯闭合,A口和B口之间中断。
因而插装阀的功能等同于2位2通阀。
故称二通插装阀,简称插装阀。
图3插装元件根据用途不同分为方向阀组件、压力阀组件和流量阀组件。
同一通径的三种组件安装尺寸相同,但阀芯的结构形式和阀套座直径不同。
三种组件均有两个主油口A和B、一个控制口x,如图4所示。

插装阀分为二通插装阀和螺纹插装阀两大类。
二通插装阀采用滑入式座阀主级和法兰固定式控制盖板,而螺纹插装阀则采用螺纹旋入并紧固的,因此,它们的结构和密封有所不同。
二通插装阀主要是用在大流量的系统中,如锻压机械、塑料机械、冶金轧钢设备、造船、铸造机械等行业。
MTechnical ReferenceHIC manifold design guidelines, tooling,torque specifications, port and cavity dimensionsT echnical Reference Section ContentsMReviewing CircuitAll designs begin with a sche-matic circuit design inspired by the application. Before the planning stage, review the design utilizing the following steps:• Match schematic symbols to model codes.• Note size and cavity of each valve and write it on schematic.• Note port numbers of the valves and write them on schematic.• Note manifold port types and sizes specified by customer.• Note pressure, flow and material of manifold block (steel or aluminum).Circuit questions should be answered by the customer before beginning a design. It is also recommended that schematic hydraulic regions or networks be color coded using color pens. Regions or net-works may be broken down in individual colors (pressure, tank, pilot, etc.) but it may be easier to design if regions are broken down into sub-regions such as pressure from port one of a solenoid valve to port two of a relief valve. Colored layers may be assigned later to match schematic circuit coloring.Initial DesignOnce the circuit is fully under-stood, it is advisable to lay the design out by hand first. Things to consider while plan-ning the design are:• Block size is often specified by customer.• Specify an overallenvelope size, in addition to the specified block size. Overall envelope size includes block size and any valves or fittings protruding from the manifold block.• Restrictions specified for a mounting surface of the manifold block. Valves and ports may be restrictedfrom a particular surface.• Specify mounting holes, threaded holes and thru holes (if necessary).• Arrange valves in a logical manner. Valves and ports in the same regions should be located in close proximity to each other.• Eliminate as many turns in the regions as possible to reduce the number of cross drill holes or construction lines. This helps keep pressure drops ( D P) andmanufacturing costs down.Material SizesTo obtain an optimal cost man-ifold it is desirable to select a standard material size for the manifold, compare the block size with the standard mate-rial size table. See Standard Material Sizes (page M-5). If a standard size is not available, a cut plate may be used. Hydraulic SchematicIf a schematic is desired on the assembly, it may be cre-ated from existing symbols. As an alternative, the entire circuit may be created outside of an assembly and imported as a symbol (block). All of the Vickers screw-in cartridge valves have schematic sym-bols which can be found in the SICV Cartridge Valve Library of Symbols CD, used in conjunc-tion with AutoCad software. Schematic symbols not found in the library may be created on an “as needed” basis.Accurate DesignAll dimensions on CAD design must be accurate and to scale in order to be utilized by CAM software in conjunction with CNC machine tools. Manually or interactively modifieddimension cannot be tolerated.Example:Note: Failure to ensure thatCAD dimensions are accurate and to scale may result in improper machinery by CNC Machine Tools.Datum PointThe datum point or origin point (0,0,0) on machining drawings is the upper left corner when facing the front view.Assembly Dimensioning Dimension all ports, mount-ing holes and overall envelope size.External ClearancesAllow enough room for clear-ance around solenoid coils, handknobs, levers and wrench clearance for fittings. If 90° elbow fittings are to be used, some may be required to swing a full 360 arc.Assembly NotesNotes are added for standard or special assembly, handling, or shipping instructions, as well as special stampings.Port T ableInclude a port table with names and sizes of all ports.Standard T oolingIn order to obtain fastturnaround on designs, limit the tooling used to that listed in the standard tooling table. See Preferred Tooling for Machining Manifolds (page M-6).General Guidelines forHydraulic Integrated Circuits (HIC)professional in the design of manifold blocks and related hydraulic systems. It is the designer’s responsibility to verify the adequacy of thedesign through approporate verifications, review and test-ing of the final design.Always “square up” the raw block before machining the cavities, ports and holes. This is to eliminate any potential “drill walk” which leads to scrapped manifolds. When squaring up a block, remove approximately 0.015” of material from each face for Aluminum blocks and 0.030” of material from each face for steel blocks. This is done to ensure that all six faces are parallel or perpendicular. Finished machining shouldreflect the squared up dimen-sions. See Standard Material Sizes (Table 1).Example: 4.0” x 5.0” x 6.0” (101.6 mm x 127 mm x 152.4 mm) block will be dimen-sioned to 3.97” x 4.97” x 5.97” (100.8 mm x 126.2 mm x 151.6 mm)Creation of MachiningT able Create a machining operation table or bore chart. Machining depths are given from the sur-face of the block. List all drill depths, mills, taps and form tools in the machining table. Call out drill depths at the shoulder depth of the drill, not to the drill point depth.All machining depths are to the corner of the full diameter as opposed to the drill point. All depths are measured from the face plane (surface) of a manifold block.Avoid any drill depths greater than 25 diameters.Additional line lengths may result in increasing pressure drops.Machining NotesMachining notes are to beadded for standard or special machining, handling and ship-ping instructions.DrillingsDrillings that go completely through a cavity port area should be on the center axis of the cavity wherever possi-ble; see Figure (a). Otherwise it should intersect the cavity tangent to the outside diam-eter of the bore it connects with; see Figure (b).Note: Breaking into a cavity at some point in between these recommended areas will lead to drill walk and can result in a high scrap rate, as well as premature drill breakage.All SAE ports and cavities have spotface depths of .031” (.8 mm) unless otherwise speci-fied. BSPP ports have spotface depths of .060” (1.5 mm) unless otherwise specified.CounterboresIn counterbore cases, the actu-al cavity spotface is located at the depth of the counterbore. When counterbore depths are greater than 0.125”, the follow-ing diameters should be used:Use of Expander Plugs and Zero Leak Gold SAE O-Ring PlugsOn small HIC packages, expander plugs can be used to block off construction drill-ing at the surface of a face. Larger than a 12mm expander plug are not recommended in aluminum. Any construction drillings larger than 0.4” (10 mm) are plugged with zero leak gold SAE O-Ring plugs (internal hex type). The machin-ing callout for these plugs can be either the industry standard SAE straight thread O-ring boss port configuration or the straight thread O-ring boss short port configuration. Refer to Port Dimensions (page M-9 and M-10).Surface T reatmentsAny manifold face that calls for a surface mounted (gas-ket mounted) valve such as a DG4V type directional control valve, or a pump or motor interface, should have a mini-mum roughness callout of 63 microinches (.0016mm) and a flatness callout of .002”(.05mm). See examples below.To prevent corrosion, steel manifolds are oil dipped or coated with rust protec-tive fluid, unless otherwise specified. To prevent oxidation, aluminum manifold blocks are gold anodize, unless oth-erwise specified. Aluminum manifolds where the internally grounded coil is used should not be anodized. Prototypes are supplied without surface treatment.Datum Point Example in orthographic third angle projection:General Guidelines forHydraulic Integrated Circuits (HIC)MWall ThicknessFor pressures up to 3000 psi (210 bar), aluminum may be used, for pressures above 3000 PSI (210 bar). Dura-Bar cast iron manifold material is recommended.Larger cavities or bores require a greater wall thick-ness.The table below shows recommended minimum wall thicknesses for Aluminum and Dura-Bar.general guidelines will notguarantee the manifold will survive any finite number of cycles. The only way to properly assure a specified life is to run a thorough testing of both burst and endurance in the actual application circuit.T able 1Standard Material SizesGeneral Guidelines forHydraulic Integrated Circuits (HIC)Creating Bill of Material – BOMDevelop a BOM that includes quantity, model codes, part numbers and descriptions of the HIC.

Speeds and/ or feeds may be increased or decreased depending on actual machining conditions.Note: Finish form tools may require 1/2 to 1 1/2 second dwell to obtain necessary finish.Finishing T oolsThese finishing tools have been designed as preci-sion reamers for finishing operations only. They are not intended for primary forming or bottom cutting operations. Vickers recommends that a finishing tool only be used in a properly roughed hole. Failure to conform to this practicewill produce unsatisfactory size and finishes and possibly break the tool.MC–**–2(P)Dimensionsmm (inch)Cavity bores can be machined accurately in aluminum or steel.

宁波华液机器制造有限公司插装阀与我们所说的普通液压控制阀有所不同,它通流量可达到1000L/min,通经可达200~250mm。
结构简单,阀芯结构简单,阀芯动作灵敏,密封性好。
它的功能比较单一,,主要实现同或断,与普通液压控制阀组合使用时,才能实现对系统油液方向、压力和流量的控制。
7.6.1 插装阀Cartridge Valve插装阀(逻辑阀),是一种较新型的液压元件,它的特点是通流能力大,密封性能好,动作灵敏、结构简单,因而主要用于流量较大系统或对密封性能要求较高的系统。
图7.15 插装阀逻辑单元(a)结构原理图;(b)图形符号图7.16 插装阀的组成1—先导控制阀(Pilot Control Valve);2—控制盖板(Control Cover);3—逻辑单元(Logic cell)(主阀)、4—阀块体(Manifold Block)(1)插装阀的工作原理插装阀的结构及图形符号如图7.15所示。
它由控制盖板、插装单元(由阀套、弹簧、阀芯及密封件组成)、插装块体和先导控制阀(如先导阀为二位三通电磁换向阀,见图7.16)组成。
由于这种阀的插装单元在回路中主要起通、断作用,故又称二通插装阀。
二通插装阀的工作原理相当于一个液控单向阀。
图中A 和B为主油路仅有的两个工作油口,K为控制油口(与先导阀相接)。
当K口无液压力作用时,阀芯受到的向上的液压力大于弹簧力,阀芯开启,A与B相通,至于液流的方向,视A、B口的压力大小而定。
反之,当K口有液压力作用时,且K口的油液压力大于A和B口的油液压力,才能保证A与B之间关闭。
插装阀与各种先导阀组合,便可组成方向控制阀、压力控制阀和流量控制阀。
(2)方向控制插装阀Direction Control Cartridge Valve图7.17 插装阀用作方向控制阀(a)单向阀(Chack Valve);(b)二位二通阀(2-Position 2-Way Valve);(c)二位三通阀(2-Position 3-Way Valve);(d)二位四通阀(2-Position 4-Way Valve)插装阀组成各种方向控制阀如图7.17所示。
1 插装阀概述时间:2021.03.11 创作:欧阳音二通插装阀是插装阀基本组件(阀芯、阀套、弹簧和密封圈)插到特别设计加工的阀体内,配以盖板、先导阀组成的一种多功能的复合阀。
因每个插装阀基本组件有且只有两个油口,故被称为二通插装阀,早期又称为逻辑阀。
1.1 二通插装阀的特点二通插装阀具有下列特点:流通能力大,压力损失小,适用于大流量液压系统;主阀芯行程短,动作灵敏,响应快,冲击小;抗油污能力强,对油液过滤精度无严格要求;结构简单,维修方便,故障少,寿命长;插件具有一阀多能的特性,便于组成各种液压回路,工作稳定可靠;插件具有通用化、标准化、系列化程度很高的零件,可以组成集成化系统。
1.2 二通插装阀的组成二通插装阀由插装元件、控制盖板、先导控制元件和插装块体四部分组成。
图1是二通插装阀的典型结构。
图1 二通插装阀的典型结构控制盖板用以固定插装件,安装先导控制阀,内装棱阀、溢流阀等。
控制盖板内有控制油通道,配有一个或多个阻尼螺塞。
通常盖板有五个控制油孔:X、Y、Z1、Z2和中心孔a(见图2)。
由于盖板是按通用性来设计的,具体运用到某个控制油路上有的孔可能被堵住不用。
为防止将盖板装错,盖板上的定位孔,起标定盖板方位的作用。
另外,拆卸盖板之前就必须看清、记牢盖板的安装方法。
图2盖板控制油孔先导控制元件称作先导阀,是小通径的电磁换向阀。
块体是嵌入插装元件,安装控制盖板和其它控制阀、沟通主油路与控制油路的基础阀体。
插装元件由阀芯、阀套、弹簧以及密封件组成(图3)。
每只插件有两个连接主油路的通口,阀芯的正面称为A口;阀芯环侧面的称作B口。
阀芯开启,A口和B口沟通;阀芯闭合,A口和B口之间中断。
因而插装阀的功能等同于2位2通阀。
故称二通插装阀,简称插装阀。
图3 插装元件根据用途不同分为方向阀组件、压力阀组件和流量阀组件。
同一通径的三种组件安装尺寸相同,但阀芯的结构形式和阀套座直径不同。
三种组件均有两个主油口A和B、一个控制口x,如图4所示。

螺纹插装阀技术螺纹插装阀技术张海平2006-11目录目录前言1. 各类螺纹插装阀:构造,工作原理和性能2. 发展历史与现状3. 螺纹插装阀的应用4. 螺纹插装阀的局限性前言前言螺纹插装阀具有体积小、结构紧凑、应用灵活、使用方便、价格低等一系列优点,在欧美被广泛应用在农机、废物处理、起重机、拆卸设备、钻井、铲车、公路建设、消防车、林业机械、轮船、油井、矿井、扫路车、挖掘机、多用途车、金属切削、金属成型、机械手、铸造、成型、造纸、纺织、包装设备、动力单元、试验台等。
1. 各类螺纹插装阀:构造各类螺纹插装阀:构造,工作原理和性能,工作原理和性能,工作原理和性能插装阀(Cartridge Valve)从安装方式上可分为滑入式(Slip-in)和螺旋式(Screw-in)这两类。
滑入式即通常所称的二通插装阀或逻辑元件,它一般都还需要附加先导控制阀才能工作。
螺旋式即本文要述及的螺纹插装阀,它(装入安装孔后)一般都能独立完成一个或多个液压功能,如溢流阀、电磁方向阀、流量控制阀、平衡阀等。
以下摘取自一些国际市场上可见产品的使用说明书,供读者具体了解螺纹插装阀。
1.1单向阀单向阀Sterling 公司的D02B2:工作压力42MPa,最大流量80升/分,总长33.7mm,安装孔内部分长27.2mm。
1.2 溢流阀Sterling公司的A04R2M:工作压力0.5-35MPa,最大流量60升/分,总长123mm,安装孔内部分长46mm,直径22mm。
1.1.33电磁方向阀电磁方向阀::滑阀滑阀Hydraforce 公司的SV10-47C:工作压力21MPa,最大流量22升/分,总长188mm,孔内部分长62mm,直径22mm。

比例流量阀1.1.77比例流量阀Hydraforce 公司的PV72-30,工作压力21MPa,最大流量64升/分,总长156mm,安装孔内部分长71mm,直径25mm。
由于螺纹插装阀结构相对简单,加工容易,通用件多,便于大批量生产,因此价格比相同功能的板式阀,管式阀低一些。
发展历史与现状发展历史与现状2.2.发展历史与现状液压出现于20世纪初,大发展则在二次大战期间。
1950年在美国出现了最早的螺纹插装阀—为美国空军,装在飞机燃料泵体上的溢流阀。
但直到60年代初,螺纹插装阀还局限于简单的功能,如止回阀,溢流阀和二位二通电磁阀。
由于重量轻,空间紧凑,被应用于农业、采矿,航海和建筑机械等中压低流量的场合。
在1970年前后,当时螺纹插装阀的主要生产商Fluid Control在欧美各地的代理商,纷纷建立了自己的生产基地和设计机构,发展自己的产品。
例如,Modular, Sun, Sterling, Wandflu, Comatrol等。
螺纹插装阀出现了大发展。
由于螺纹插装阀可以有4端口,甚至6端口,因此相对二通插装阀有大得多的变化可能性。
到了80年代,形成了全方位供应商,被市场普遍接受。
迄今世界上已有上百家公司可以提供螺纹插装阀、阀块,并为顾客设计专用集成块。
主要基地在美国的有Hydraforce、Sun hydraulics、Fluid Power Systems、Delta Power、Waterman-Parker Hannifin、Fluid Control (Danfoss)、Eaton-Vickers等,在英国的有Sterling hydraulics、Integrated hydraulics,在瑞士的有Wandfluh、Bucher-Frutigen,在意大利的有Comatrol、Oil-Control,在德国的有Bosch-Rexroth、HYDAC、IMAV、Tries、Fluid Team等等。
其中许多厂的螺纹插装阀及阀块的年销售值都达到几千万乃至上亿美元。
2002年,仅Bosch-Rexroth集团一家就生产了350万件螺纹插装阀。
螺纹插装阀经过许许多多大大小小公司成千上万的技术人员持续研究改良几十年,品种纷繁。
例如,Integrated Hydraulics 公司2003年的产品样本有约300页,260种基本类型,SUN 公司2001/02年的产品样本有四百余页,约280种基本类型;ST 公司2003年的产品样本有585页,约320种基本类型;HF 公司2003年的产品样本约900页,介绍了约400类产品。
他们为顾客提供特殊设计的产品品种还数倍于此。
例如, 溢流阀溢流阀普通溢流阀:直动型(a1) 球阀型、锥阀型、带增强阻尼型、侧面入流型、滑阀型、先导型(a2);压力保险阀(b1); 带反向单向阀的溢流阀(c1);双向型溢流阀(d1, d2);遥控型溢流阀:失压卸荷型(e1)、加压卸荷型(e2)、卸荷加压型(e3) 、气控比例(e4)、电控开关型(e5),电控比例型(e6、e7)。
还有许多特种溢流阀,如埋入式热保护,双通道先导用溢流阀,软溢流阀。

没有生产商能够提供所有类型。
精益求精,不断创新已有宽广的产品型谱,相当的可靠性。
但还在不断改进,不断扩展,每年推出新产品,追求完美。

它可以单独装入与其配用的单阀块或双阀块(阀供货商一般都能同时提供这类阀块),成为管式元件。
它也可以装入液压马达、液压泵体,或液压缸接口处,作为控制阀。
它也可以装入带CETOP接口的阀块,成为竖式叠加阀、或横向片状组装阀。
它也可以装入二通插装阀的控制盖板,作为先导控制。
最后,它也可以装入自行设计的专用(纯)螺纹插装阀集成块,例如以下三个由笔者自行或指导设计的阀块。
例一。
这个回路可以控制一组单向液压缸,按预设定的速度升,靠自重降。
最大输入流量可达70升/分,输出流量0至30升/分,压力至21Mpa。
7个螺纹插装阀(Sterling公司)。
铝合金阀块135X 135X60mm,连阀占用空间245X225X 60mm。
例一例二。
这个回路使用比例流量阀和比例溢流阀,可以控制两组单向液压缸,独立或并行,按给定的速度升,靠自重降,限速,可调。
最大输入流量可达60升/分,两路输出流量分别为0至22升/分,压力至21Mpa。
10个螺纹插装阀,多为Hydraforce产品。
铝合金阀块140X140X80mm,连阀占用空间280X230X80mm。
例一和例二的纵向都限制在80mm以下,垂直和水平向所允许的空间也极其有限,包括其一些功能要求,都是用普通的管式和板式阀是很难实现的。
例二例三。
前二例皆为电控,此阀块系为配合手动阀而设计,可以分别控制两组半双向液压缸,按预设定的速度和压力升出和收回。
最大输入流量可达40升/分,压力至21Mpa。
14个螺纹插装阀,使用SUN和Sterling等的产品,铝合金阀块90X90 X198mm。
连阀占用空间90X186X288mm。
四个与阀连接的接口间距与阀的出口间距相同,因此可以用短直管连接。
比以前使用管式阀大大缩小了占用空间,缩短了组装时间,特别是在装配流水线上的组装时间,减少了可能泄漏的部位数,降低了管道与接头引起的压力损失,便于整块更换,降低了对现场维修人员的技术水平要求,缩短系统停工期。
例三螺纹插装阀的局限性4. 螺纹插装阀的局限性当然,螺纹插装阀也有其局限性,表现在以下几方面。
互换性差4.1互换性差除电磁线圈不兼容以外,安装孔也不一样,不能简单换。
从1982年起,就在蕴酿制定国际标准,统一安装孔形式,以改善互换性,但直到1998年使用公制螺纹的ISO7789才获多数通过。
但仅两年后,12个美国螺纹插装阀生产商就又提出了一个使用UN(Unified Coarse thread)和UNF(Unified Fine thread)螺纹的国际标准草案CAD17209,得到了不少赞成票,但在美国有重要市场地位的SUN公司既未参加也未拒绝。
欧洲许多专家则表示反对,一是认为安全问题未得到足够重视,二是反对一个产品两个标准。
另一方面ISO7789的市场化进展也非常缓慢,至今仍无一家公司推出完整的ISO系列阀。
正如所比喻的,“火车已经(向四面八方)开走了,”再要它们回到一条轨道上来,就很难了。
中小流量4.4.22中小流量由于螺纹强度和紧固扭矩的限制(500Nm),螺纹插装阀的直径只能做到48mm,相应于二通插装阀通径16,25,流量400、500升/分左右,再大就是二通插装阀的天地了。
