Chuanxi fluids share with you about the use of pneumatic sanitary diaphragm valve equipment:
装拆快捷， 操作灵活简单，流体的阻力较小，使用安全可靠性等优点。 The sanitary valve of the pneumatic sanitary diaphragm valve adopts the hoop type, and has the advantages of simple structure, beautiful appearance, fast opening and closing, fast assembly and disassembly, flexible and simple operation, small fluid resistance, and safety and reliability. The sanitary diaphragm valve is remotely controlled by a driving device or manually operated by a handle. The driving device has the following three standards: normally closed, normally open, and air type. 适用于化工、石油、冶金、水暧、食品、药品等行业的水、气、油品及腐蚀性介质的控制。 Sanitary diaphragm valve is suitable for the control of water, gas, oil and corrosive media in chemical, petroleum, metallurgy, water, food, pharmaceutical and other industries.
The reason for the structural design of the diaphragm valve is especially suitable for ultra-pure media or heavily polluted, very viscous liquids, gases, corrosive or inert media. When combined with control equipment, diaphragm valves can replace other traditional control systems, especially for solid and easily contaminated inert media. All steel parts are made of acid-resistant stainless steel, and the seals are made of food silicon rubber or polytetrafluoroethylene, which meets food hygiene regulations. Generally applicable to many industries such as food, brewing, beverages, dairy products, fine chemical pharmaceuticals and biological engineering.
特点： Features of pneumatic sanitary diaphragm valve equipment :
1. The reason for the structural design of the diaphragm valve is particularly suitable for ultra-pure media or heavily polluted, very viscous liquids, gases, corrosive or inert media. When combined with control equipment, diaphragm valves can replace other traditional control systems, especially for solid and easily contaminated inert media.
2. The sealing principle of the diaphragm valve is to press down the diaphragm or diaphragm assembly and the channel of the weir-type lining valve body or the straight-line lining valve body by the downward movement of the operating mechanism to make it sealed. The specific pressure of the seal is achieved by the downward pressure of the closing member. Since the valve body can be lined with various soft materials, such as rubber or Teflon; the diaphragm is also made of soft materials, such as Teflon lined with rubber or synthetic rubber, so it can be achieved with a small sealing force Fully sealed.
3. The diaphragm valve has a simple structure, low fluid resistance, and larger flow capacity than other types of valves of the same specification; it has no leakage and can be used for the regulation of high viscosity and suspended particulate media. The diaphragm isolates the medium from the upper cavity of the valve stem, so there is no leakage of the medium without packing. However, due to the limitation of the diaphragm and lining materials, the pressure resistance and temperature resistance are poor, and it is generally only applicable to a nominal pressure of 1.6MPa and below 150 ° C.
4. Diaphragm valve replaces the valve core assembly with a valve body with a corrosion-resistant lining and a corrosion-resistant diaphragm, and uses the movement of the diaphragm to adjust. The valve body material of the diaphragm valve is cast iron, cast steel, or cast stainless steel, and lined with various corrosion-resistant or wear-resistant materials, diaphragm material rubber and polytetrafluoroethylene. The lining diaphragm has strong corrosion resistance and is suitable for the adjustment of strong corrosive media such as strong acid and alkali.
