On the type of feeding pneumatic valve and show what is the difference between feeding pneumatic valve

show the difference between feeding pneumatic valve: up and down on the exhibition of pneumatic valve for the ball to rise to discharge, the exhibition of pneumatic valve as the ball fell to discharge. Sealing ring, scouring and corrosion resistant material is adopted, and the sealing ring for special treatment, the surface hardness of HRC - , make sure when the pneumatic valve is opened, inner chamber is not damaged by corrosion fluid and debris, has the function of high wear resistance, corrosion resistance, working condition of special pneumatic disc can be sealed when welding into cemented carbide, seal line sealing, which can effectively ensure the reliable performance of the pneumatic valve, can prevent scarring, corrosion, etc.
feeding structure performance of pneumatic valve:
yongjiaxian sanjing brand feeding pneumatic valve has simple structure, convenient operation, reliable open free, flexible movement, pneumatic disc and seal ring for easy replacement. Feeding pneumatic valve is mainly composed of pneumatic valve, pneumatic valve, sealing ring, pneumatic valve stem, stents, pneumatic valve gland, hand wheel, flange, nuts, positioning screw, etc. Feeding pneumatic valve in the chemical, oil, metallurgical, pharmaceutical, pesticide, dye, food processing industries have been widely used.
feeding medium use pneumatic valve:
feeding pneumatic valve: glass lining equipment is high silicon content in the vitreous glaze. By degrees high temperature coating on metal bond. It has good mechanical properties and corrosion resistance performance, can prevent the medium and the metal ions affect pollution products instead of role, and the surface is bright and clean, wear-resisting, there is a certain thermal stability.
(1) when the medium is water, acetone, alcohol, ammonia, barium carbonate, benzene and other corrosive fluid, temperature range in - ℃, Choose WCB ℃.
(2) using the medium for grain, oil, pulp, stainless steel material should be used when the carbon dioxide, temperature shall not exceed the scope of - ℃, ℃.
3. It is forbidden to use fluoride ion liquid ( Also can't use strong alkali and phosphate (such as HF Temperature less than ℃, the concentration & gt; %。
seller corrosion resistance:
, general inorganic acid, organic acid, weak alkali ( P ℃ or less PH and organic agent medium or less.
, such as hydrochloric acid, nitric acid, strong corrosive medium is better than stainless steel.
denominated in strong alkali and phosphate ( Temperature less than ℃, the concentration & gt; %。
to heat resistance, allowing the in - ℃, Using (between ℃ Leaps of heat-resistant less than ℃.
looking insulation, impact resistance performance for g/cm smaller, and therefore should be avoided when using hard objects.
feeding pneumatic valve installation points:
1. This product is commonly installed horizontally.
(2) the installation position, height, import and export direction must comply with the design requirements, the connection should be firmly connected.
(3) is installed on the thermal insulation pipe of all kinds of manual, pneumatic valve handle shall be down.
