Type of pneumatic diaphragm single seat control valve
调节阀经过多年的发展，已经有了非常好的基础和底蕴。 After many years of development, China's pneumatic film single-seat control valve has a very good foundation and background. 调节阀的发展也得到了更多支持。 As the use of such products has been affirmed and appreciated by more and more users, the development of pneumatic diaphragm single-seat control valves has also received more support. To speed up the further improvement of pneumatic diaphragm single-seat control valves, the most important of which is the further expansion of the types of pneumatic diaphragm single-seat control valves.
So what are the types of pneumatic single-seat control valves in China? Based on what kind of pneumatic diaphragm single seat control valve is classified?
Pneumatic film single seat regulating valve:
1. According to purpose and function (1) two-position valve; (2) regulating valve; (3) diverter valve; (4) shut-off valve;
2. Classified according to the working temperature of the medium (1) high temperature valve; (2) medium temperature valve; (3) room temperature valve; (4) low temperature valve;
真空阀；(2)低压阀；(3)中压阀；(4)高压阀；(5)超高压阀； 3. Classified by pressure (1) vacuum valve ; (2) low pressure valve; (3) medium pressure valve; (4) high pressure valve; (5) ultra high pressure valve;
4. Commonly used classification method This classification method is divided according to principle, function and structure. It is currently the most commonly used classification method at home and abroad. 隔膜阀；(7)蝶阀；(8)球阀；(9)偏心旋转阀； Generally divided into nine categories: (1) single-seat regulating valve; (2) double-seat regulating valve; (3) sleeve regulating valve; (4) angle regulating valve; (5) three-way regulating valve; (6) Diaphragm valve ; (7) butterfly valve ; (8) ball valve ; (9) eccentric rotary valve;
球阀；(20)烧碱专用阀； 5. Special applications (1) soft-sealed shut-off valve; (2) hard-sealed shut-off valve; (3) wear-resistant regulating valve; (4) corrosion-resistant regulating valve; (5) all-tetrafluoro-corrosion regulating valve (6) full Corrosion-resistant alloy regulating valve; (7) emergency action cut-off or vent valve; (8) anti-blocking regulating valve; (9) corrosion-resistant anti-blocking shut-off valve; (10) insulation jacket valve; (11) large pressure drop shut-off valve (12) small flow regulating valve; (13) large diameter regulating valve; (14) large adjustable ratio regulating valve; (15) low S energy saving regulating valve; (16) low noise valve; (17) fine small regulating valve (18) Lining (rubber, tetrafluoro, ceramic) regulating valve; (19) Special ball valve for water treatment ; (20) Special valve for caustic soda;
Through the analysis of the classification of the above-mentioned five-point pneumatic diaphragm single-seat control valves, we can understand the classification of pneumatic diaphragm single-seat control valves intuitively. China is a large developing country, and various industries are developing healthily and rapidly. 阀门的需求也不断膨胀，如何进一步扩大气动薄膜单座调节阀的市场竞争力，加快对气动薄膜单座调节阀种类研究十分必要。 The demand for valves in many industries is also expanding. How to further expand the market competitiveness of pneumatic film single-seat control valves and accelerate the research on the types of pneumatic film single-seat control valves are necessary.
