The composition and working principle of diaphragm valve

     The composition and working principle
      The corrosion-resistant lining diaphragm valve and corrosion resistance diaphragm valve assembly instead of using, regulate the movement of the diaphragm. Diaphragm valve body materials made of cast iron, cast steel, or cast stainless steel, and lined with a variety of corrosion or abrasion resistant materials, rubber and PTFE membrane material. Corrosion resistant lining of the diaphragm, regulation suitable for acid, alkali and other strongcorrosive media.
      Other types of valve diaphragm valve of simple structure, small fluid resistance, flow capacity than the same specification; no leakage,can be used to adjust the high viscosity and suspended particles in the medium. Diaphragm to the media and the stem cavity isolation,so there is no packing medium does not leak. However, due to the diaphragm and the lining material limit, pressure resistance,temperature resistance is poor, generally applies only to 1.6MPanominal pressure and 150 ℃.
Engineering Chain

Engineering Chain

     The flow characteristics of the diaphragm close to the features quick, in 60% of stroke is approximately linear, 60% of the traffic changes. Pneumatic diaphragm valve can still be attached to the form of feedback signal, limiting device and a positioning device, in order to meet the needs of automatic control, control or regulate the flow. Non contact sensing technology pneumatic diaphragm valve feedback signal. This product uses the film propulsion cylinder, replace the piston cylinder, ruled out the piston rings are easily damaged, resulting in leakage caused by the drawbacks that can not push the valve opening and closing. When the gas supply failure, can open and close the valve handwheel.
