压力释放阀PRESSURE RELEASE VALVE使用说明书OPERATION INSTRUCTION明远电器设备SHENYANG MINGYUAN ELECTRIC EQUIPMENT CO., Ltd.本说明书适用于我公司生产的系列变压器用压力释放阀，阐述其用途、性能、规格、技术参数、使用及安装，供用户参考。

The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.1. 压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。

当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms迅速动作，释放压力，保护油箱不致变形或爆裂。

油箱的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱的压力降到正常值。

由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器部不会受大气污染。

1.Application and performancePressure release valves play a vital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid build-up of gaseous pressure? If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.2．型号、规格及基本参数Type, specification and technical parameters2.1 型号的含义 Meaning of typeY S F□—□ / □□□特殊环境代号（Special environment）带机械信号标“J”（“J”：mechanical signal）带信号开关标“K”（“K”：electrical signal）两者都带标“KJ”（“KJ”：Both with signal）喷油有效口径（Caliber of oil-gushing tube）mm开启压力（Opening pressure）kPa设计序号（Design serial number）阀（valve）释放（release）压力（pressure）注：特殊环境代号 note: special environment:TA: 干热带地区 dry tropicTH: 湿热带地区 humid tropicT: 干、湿热带地区 dry、humid tropic例：YSF16-55/130KKJT开启压力为55kPa，喷油口径为φ130mm，带电信号、机械信号。

压力释放阀工作原理压力释放阀是一种常见的工业设备，其主要功能是在工作过程中释放压力，以保护相关设备或系统的安全运行。

它在各种行业中广泛应用，如石油化工、电力、制药等。

压力释放阀的工作原理是通过调节阀门的开度来控制介质的流量，从而实现压力的释放。

压力释放阀通常由阀体、阀盖、阀芯、弹簧等组成。

当介质压力超过设定值时，阀芯会受到压力的作用而打开，介质经过阀门流出，从而降低了系统的压力。

当压力降至设定范围内时，阀芯会关闭，停止介质的流动，保持系统的稳定压力。

压力释放阀的工作原理可以用以下几个步骤来描述：1. 设定压力范围：在使用压力释放阀之前，需要根据实际需求设定阀门的工作压力范围。

这通常是通过调节阀芯上的调节螺钉来实现的。

调节螺钉的旋转方向和角度决定了阀芯的开启程度，从而影响介质的流量和压力释放的效果。

2. 压力感应：当系统内部压力超过设定值时，压力释放阀会感应到这一变化。

这是通过阀盖上的压力传感器来实现的。

一旦压力超过设定值，传感器会将信号传递给阀芯，触发阀芯的开启动作。

3. 阀芯开启：当接收到传感器信号后，阀芯会受到压力的作用而打开。

阀芯上的弹簧起到平衡压力的作用，使阀芯能够在合适的压力下保持开启状态。

开启后，介质会通过阀芯的通道流出，从而降低系统的压力。

4. 压力释放：介质流经阀芯通道后，会进入阀体的出口，并被导向到排放管道中。

在这个过程中，阀芯的开启程度决定了介质的流量，从而影响了系统的压力释放效果。

通过调节螺钉的旋转方向和角度，可以进一步调整阀芯的开启程度，从而实现对压力释放的精确控制。

5. 压力恢复：一旦系统的压力降至设定范围内，传感器会停止传递信号，阀芯受到弹簧的作用而关闭。

在关闭状态下，阀芯会阻止介质继续流出，系统的压力得以恢复和稳定。

压力释放阀的工作原理简单而有效。

通过调节阀芯的开启程度，可以精确控制系统的压力，从而保护设备和系统的安全运行。

压力释放阀的应用范围广泛，在工业生产中起到了重要的作用。

4.2工作原理压力释放阀是用来保护油浸式变压器等电气设备过压力保护的安全装置，可以避免变压器油箱变形或爆裂。

当油浸式变压器内部发生事故时，油箱内的油被气化，产生大量气体，使得油箱内部压力急剧升高。

此压力如果不及时释放，将造成油箱变形或爆裂。

安装压力释放阀就是当油箱内压力升高到压力释放阀的开启压力时，压力释放阀在2ms内迅速开启，使得油箱内的压力很快降低。

当压力降到压力释放阀的关闭压力值时，压力释放阀又可靠关闭，使得油箱内永远保持正压，有效地防止外部空气、水气及其他杂质进入油箱；在压力释放阀开启同时，标志杆向上动作且明显伸出顶盖，表示压力释放阀已动作过，在压力释放阀关闭时，标志杆仍滞留在开启后的位置上，然后必须由手动才能复位。

Thread M22x1,5 for cavity according to ISO 7789. These plug & play valves are factory set and adjusted. High valve-to-valve reproducibility. Housing for electronics with protection class IP67 for harsh environment. As standard versions, 6 pressure ranges are available: 20, 40, 63, 100, 160, 200, 315 and 350 bar. Good flow performance due to the differential area principle. Small leakage along the poppet guide. Adjustment by a Wandfluh (VDE-Norm 0580) proportional solenoid. The cartridge and the solenoid made of steel are zinc coated and therefore rust-protected.FUNCTIONThe valve limits the pressure in the port P (1) and reliefs the volume flow to tank port T (2). The back pressure in T (2) influences the pressure in P (1). The reliefed pressure drops with rising solenoid current (inverse function), and the with deenergised solenoid, a maximum pressure is present. The control connection is provided by an analog interface or a fieldbus interface (CANopen or Profibus DP). Parameter setting and diagnosis with the free-of-charge software «PASO» or via fieldbus interface. After taking off the cover of the electronic housing, the serial interface to adjust the settings is accessible. The menu controlled Windows program «PASO» allows easy adjustment of all variable settings. Data are stored in a non-volatile memory. Even after an electric power failure settings can easily be reproduced and transmitted.APPLICATIONProportional pressure relief valves with inte-grated electronics are well suited for demanding applications, in which the pres-sure frequently has to be changed. They are implemented in systems calling for good valve-to-valve reproducibility, easy installati-on, comfortable operation and high precision in industrial hydraulics as well as in mobile hydraulics. The proportional pressure relief catridge is very suitable for mounting in control blocks, flange bodies and sandwich plates size NG4-Mini and NG6. (Please note the separate data sheets in register 2.3). Cavity tools are available for machining the cavities in steel and aluminium (hire or purchase).

减压阀使用说明一、安装与使用1.安装减压阀之前必须对管路系统进行冲洗清理，以防焊渣、氧化皮等赃物流入阀内，影响阀门正常工作。

2.减压阀应安装在便于操作和维修的地方，并且必须直立安装在水平管路上，应注意管路中介质的流向与阀体上箭头所示方向一致，切勿装反。

3.减压阀在安装使用时，应先把旁通管路上的截止阀打开，排除管路中的冷凝水和汽水混合物，以防减压阀开启时产生水击现象损坏减压阀；当无异常现象后，按顺时针方向缓慢旋转调节螺钉，将出口压力调至所需压力（以阀后表为准），调整好后将锁紧螺母背面，拧上防护罩。

4.减压阀前应安装过滤器，以防止介质中的杂质进入减压阀，影响其性能。

5.安装的减压阀前后应有一段直管，阀前直管长度约为600mm，阀后直管长度约为1000mm。

二、如出口压力高于所需压力，需要重新设定，方法如下：①关闭上游隔离阀；②把出后压力泄掉；③将导阀调节螺钉逆时针旋松，使调节弹簧处于自由状态；④慢慢开启上游隔离阀至全开；⑤顺时针慢慢向下拧紧导阀调节螺钉，出后压力逐步升高，直到设定值时将调节螺母锁定；⑥如果调压过头，须从第一步开始重新调节，即只能从低压往高压调。

电磁阀使用说明一、本阀适用于以蒸汽为加热介质，进行温度自动控制的执行机构。

可对蒸汽加热器、散热器、干燥器等蒸汽设备及各类温度自控仪、蒸汽定型机、蒸染机、蒸汽回潮机等成套设备的锅炉蒸汽管道进行二位式自动控制和远程控制。

广泛应用于染化、纺织、印染、食品、医药、卷烟、水泥制品、石油化工、冶金等部门的自控系统。

二、主要特点耐热：电磁部分、密封件部分用特种耐高温电工材料和密封材料，并应用了各种隔热措施。

耐磨：选项材合理，阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损。

耐冷凝：蒸汽管道的冷凝水是影响蒸气电磁阀动作的重要因素，本阀则不受冷凝水影响。

三、结构原理本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀。

是靠副阀的启闭来控制主阀的通断。

根据断电时所处开关状态的不同，可分为常闭电磁阀和常开电磁阀。

采技服公司定压放气阀产品说明一、定压放气阀生产调试1、调试定压放气阀之前先将其完全关闭，确认套管压力表工作正常后，将定压放气阀出口端球阀和其进口端套管翼阀打开。

2、缓慢旋转压力调节手柄，开启（逆时针旋转压力调节手柄）定压放气阀，压力调节手柄旋转一圈后，定压放气阀的起跳压力为4Mpa，随后每开启一圈起跳压力下降0.4-0.6Mpa。

3、旋转压力调节手柄，将其起跳压力调至该井设定套压值处，稳定20分钟。

如套压高于该井设定套压，继续开启放气阀。

4、如套压高于该井设定套压，开启放气阀半圈，否则关放气阀半圈，稳定20分钟。

5、如套压仍高于该井设定套压，重复第4步，当套压稳定在设定套压后，该井定压放气阀调节完毕。

注意：因流程回压不同，或者各井套管气量大小不一，在设定套压相同情况下，各井压力调节杆开启圈数亦不同。

6、对于套压较高的井（套压>5Mpa）,调试时要分步调节。

每次调节使套压下降0.5Mpa，稳定20分钟，待流程稳定后，继续进行。

避免影响流程，尽量减少因套管放气产生压力波动，导致流程高压报警等事件发生。

7、所有井在调试后，由于放气流程的不稳定，可能会引起调节后的套压与设计套压有偏差，需要对定压放气阀进行进一步调节（执行第四步）。

二、定压放气阀的维护1、定压放气阀在工作的过程中，密封件长期在套管气的冲击、腐蚀下可能会被损坏，导致其密封性能逐渐下降。

破坏比较严重时会失去其密封性能，使定压放气阀漏气。

发现漏气，及时关闭定压放气阀两端的阀门，泄压后打开压帽，取出密封件进行更换。

更换后，按照“定压放气阀生产调试”操作规程重新调试。

2、在平时检查的过程中，如果发现定压放气阀调节能力失去作用，不能按要求控制套管压力，需要更换定压放气阀的压力调节弹簧。

关闭定压放气阀两端的阀门，泄压后，打开压帽，取出弹簧进行更换。

更换后，按照“定压放气阀生产调试”操作规程重新调试。

3、收拾整理工具，清理作业区卫生。

三、定压放气阀拆卸操作规程1、关闭套管翼阀和定压放气阀针型阀及其旁通，从放气口泄压（需要事先同时平台安全监督，杜绝此时进行进口区动火作业），直至套压表指针归零，确保压力全部泄掉；2、拆卸压帽、调节杆；3、取出锥形杆及弹簧，清理里面的原油或污物；4、对调节杆、弹簧及阀杆除锈，更换损坏的盘根、弹簧及阀杆，抹上黄油，清理丝扣，各部件归复原位；5、恢复原流程，开套管翼阀，检查定压放气阀有无泄露；6、开旁通阀门，根据平台要求，按照“定压放气阀生产调试”操作规程重新调试调试套压；7、收拾整理工具，清理作业区卫生。
