海王公司有权针对产品的设计和规格进行修改而不另行通知 海王系列隔膜阀 Haiwang Series Diaphragm valve 1、应用场合Application scopes 在涉及磨损性或腐蚀性浆料,粉状物或粒状物的关闭或控制操作时,隔膜阀是最佳的选择方案之一。The diaphragm valve is one of the best options when closing or controlling the abrasive and corrosive slurry , and powder or particulate materials.

2、Technical parameters技术参数 Size range: DN20、40、50, etc. Temperature range: 0-80 degrees Celsius. Nominal pressure: 1.0MPa Close part: Rubber diaphragm

3、性能特点Performance characteristics 隔膜阀是一种特殊形式的截断阀,其启闭件是一块用软质材料制成的隔膜,它将阀体内腔与阀盖内腔隔开。Diaphragm valve is a special cut-off valve with the on-off piece being diaphragm made of soft material to divide the inner cavity into valve body and the valve cover. 3.1 可实现100%气泡级密封,保证下游绝对零泄漏。100% gas seal can be achieved to ensure no leakage in downstream. 3.2 双向全通径流道,减小压降,降低磨损,延长使用寿命。Bi-directional and full flowing path can reduce pressure drop, weaken abrasion and prolong the service life. 3.3 自动清洁,不会卡住或堵塞。Automatic cleaning for no stuck or blocked condition. 3.4 完全免维护设计。Completely free maintenance. 3.5 无金属部件与料浆直接接触。No direct contact between metal parts and slurry. 海王公司有权针对产品的设计和规格进行修改而不另行通知

3.6 模块化设计的隔膜,方便使用者自行更换。Modular designed diaphragm for ease of replacement .

7、阀门与管道连接Connection of valve and pipe 阀门与管道连接过程中不允许阀门直接受力。No direct force is allowed during the connection process of valve and pipe .

8、使用与维护Use and maintenance 8.1 避免碰撞阀门气缸或手轮。Avoid collision of valve cylinder or hand wheel. 8.2 该类阀门的使用压力不得大于1.0MPa,若超过此范围请在订货时另作说明。Operating pressure should be less than 1.0MPa, and please make a note at the time of order if greater pressure required. 8.3 手动阀门操作时严禁使用加力杆、撬杠等省力装置。Labor-saving devices such as reinforcing bar and crowbars are strictly prohibited for manual valve operation. 8.4 为保证使用安全和用户的正常生产,建议每两年更换一次隔膜。 It is suggested to replace the diaphragm every two years to ensure the safe use and normal production.

9、隔膜更换Diaphragm replacement 海王公司有权针对产品的设计和规格进行修改而不另行通知

9.1 拆卸阀盖与阀体连接的螺栓。 Remove the bolt from the valve cover and valve body. 9.2 打开阀盖,逆时针转动隔膜,取下损坏的隔膜。Open the valve cover, turn the diaphragm counter clockwise and remove the damaged diaphragm. 9.3 换上新隔膜,安装阀盖并连接所有紧固螺栓。Replace the new diaphragm, install the valve cover and connect all the fastening bolts. 10、故障与处理Fault and treatment

序号No. 故障现象Fault 原因分析 Cause analysis 排除方法 Treatment

1 手轮转动费力或有卡阻现象。Inflexible or locking phenomenon appears for handwheel rotation. 阀杆螺纹过脏或腐蚀The stem threads are dirty or corroded.

清除螺纹内的夹杂、灰尘和锈蚀,涂敷润滑脂Remove impurities, dust or rust in the thread and fill greases

2 阀体出现渗漏Leakage of the valve body 1. 隔膜损坏Diaphragm damage 2. 阀体衬胶磨漏Lining rubber of valve body grinds leakage 1. 更换新隔膜 Replace new diaphragm 2. 更换新阀门Replace the valve

3 阀门完全打开后管道内没有物料流出no material flows out of the pipe after the valve being fully open 长时间使用后隔膜老化Diaphragm aging caused after long-term use

1. 反复开关阀门2次Repeated switching valve 2 times

2.更换新的隔膜Replace new diaphragm
