進口隔膜閥用耐腐蝕襯里的閥體和耐腐蝕隔膜代替閥芯組件，利用隔膜的移動起調(diào)節(jié)作用。隔膜閥的閥體材料采用鑄鐵、鑄鋼，或鑄造不銹鋼，并襯以各種耐腐蝕或耐磨材料、隔膜材料橡膠及聚四氟乙烯。襯里的隔膜耐腐蝕性能強，適用于強酸、強堿等強腐蝕性介質(zhì)的調(diào)節(jié)。

隔膜閥的結(jié)構(gòu)簡單、流體阻力小、流通能力較同規(guī)格的其他類型閥大；無泄漏，能用于高粘度及有懸浮顆粒介質(zhì)的調(diào)節(jié)。隔膜把介質(zhì)與閥桿上腔隔離，所以沒有填料介質(zhì)也不會外漏。但是，由于隔膜和襯里材料的限制，耐壓性、耐溫性較差，一般只適用于1.6MPa公稱壓力和150℃以下。

隔膜閥的流量特性接近快開特性，在60%行程前近似為線性,60%后的流量變化不大。

氣動形式的隔膜閥尚可附裝反饋信號、限位器及定位器等裝置，以適應(yīng)自控、程控或調(diào)節(jié)流量的需要。氣動隔膜閥的反饋信號采用無觸點傳感技術(shù)。該產(chǎn)品采用薄膜式推進氣缸，替代活塞氣缸，排除了活塞環(huán)易損壞，造成泄漏而導(dǎo)致無法推動閥門啟閉的弊端。當氣源發(fā)生故障時，尚可操作手輪使閥門啟閉。

The composition and work characteristics of the diaphragm valve Regulate the diaphragm valve diaphragm instead of the spool component corrosion-resistant lining of the body and resistance to corrosion, the use of the diaphragm move. Diaphragm valve body materials made ??of cast iron, cast steel or cast stainless steel, and lined with a variety of corrosion or wear-resistant materials, diaphragm materials, rubber and PTFE. The lining membrane corrosion resistance, applies to the regulation of acid, alkali and other strong corrosive media. The diaphragm valve of simple structure, small fluid resistance, and flow capacity than other types of valves with the specifications; no leakage, can be used for high viscosity and suspended particles in the medium adjustment. Diaphragm to the media and the stem cavity isolation, so there is no packing medium does not leak. However, due to the limitations of the diaphragm and lining materials, pressure, temperature resistance and poor, generally apply only to 1.6MPa Nominal pressure and 150 ° C or less. The flow characteristics of the diaphragm close to the features quick, before 60% ??of stroke is approximay linear, 60% of the traffic changes. Aerodynamic form of the diaphragm valves can still be attached to the feedback signal, stopper and locator devices, to adapt to the needs of self-control, program control or regulate traffic. The pneumatic diaphragm valve feedback signal using non-contact sensor technology. This product uses the film propulsion cylinder, replace piston cylinder, ruled out the piston rings are easily damaged, resulting in leakage caused by the drawbacks that can not push the valves open and close. When the gas supply fails, they can still handwheel valves open and close.
