Corrosion resistant lining fluoride diaphragm valve basic series lining for all G41F46, EG41F46, weir and G45F46 once-through. Composite diaphragm valve in the lower part of the body cavity with the valve cover inner chamber is separated, and the formation of dc channel, make the diaphragm of the upper stem and disc on a completely isolated from medium, save packing seal structure, the medium of leakage and leakage can be avoided. Evenly coated on the surface of a layer of FEP. Body channel inner surface is smooth, fluid resistance small, CV value is high, the flow capacity is strong, torque is moderate, use level 4 seal structure and outside the sealing surface with heat-resistant anti-aging SI rubber elastic gasket seating, completely to achieve zero leakage of the medium. The structure of diaphragm valve and valve is generally not the same, it is depend on the soft rubber or plastic film to control fluid motion. Common diaphragm valve diaphragm material divided into cast iron valve, cast steel diaphragm valve, stainless steel diaphragm valve, plastic diaphragm valve.耐腐蚀衬氟隔膜阀的原理。

耐腐蚀衬氟隔膜阀基本系列为全衬里G41F46、EG41F46、型堰式和G45F46型直流式。复合隔膜阀将阀体下部内腔与阀盖内腔隔开,并与之形成直流通道,使隔膜上部的阀杆、阀瓣等内件与介质完全隔离,省去填料密封结构,介质的内漏和外漏可同时避免。表面均匀包覆一层FEP。阀体通道内表面光滑,流体阻力小,CV值高,流通能力强,扭矩适中,采用四级密封结构并在密封面外配以耐温抗老化的SI橡胶的弹性衬垫阀座,完全达到介质的零泄漏。隔膜阀的结构形式与一般阀门很不相同,它是依靠柔软的橡胶膜或塑料膜来控制流体运动的。常用的隔膜阀材质分为铸铁隔膜阀,铸钢隔膜阀,不锈钢隔膜阀,塑料隔膜阀。耐腐蚀衬氟隔膜阀的原理。
