Stainless steel check valve structure, installation and use
Stainless steel check valve structure and installation using stainless steel check valve by rotating the valve stem to keep the valve open or closed.
Can be full size ball valve, 90 Angle, light ball valve switch, small size, can make large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion.
Stainless steel check valve can be divided into low pressure stainless steel check valve and pressure stainless steel check valve.
Low pressure check valve, stainless steel material widely, and internal parts materials are not only the color with 316 surface plating nickel material, sealing ring using special polymer materials.
Ability to make the valve not only corrosion resistance, resistance to sulfide, fire prevention, anti-static, good seal performance, working pressure and temperature range is wide, full size and reducing ready, and can match a variety of device drivers, is a chemical, oil refining, ju gas mining and conveying system ideal valve selection;
Stainless steel check valve in the line is mainly used for cutting, distribution, and change the flow direction of medium.
Using the built-in discharge valve, the valve body lumen to emissions;
Pivot structure of blow-out proof protection, effectively prevent leakage;
Low friction coefficient of the bearing, makes the minimum torque, facilitate the valve opening and closing;
Stainless steel check valve stem and valve body effective contact, make the anti-static grounding device performance is superior, with excellent performance, high reliability, wide range of USES, the price is reasonable, etc.
Stainless steel check valve is mainly used in chemical, petroleum, natural gas, metallurgy, and other industries and medium containing hydrogen sulfide, impurities, serious corrosion of gas pipeline.
Stainless steel check valve installation and use of note: 1.
Vertical elevating disc check valve should be installed in vertical pipe runs;
Elevating the level of disc check valve should be installed in horizontal pipe runs;
When installation should pay attention to the medium flow direction ticket direction arrow is consistent with the valve body;
Do not make the check valve in the line to bear weight, large check valve shall be independent support, make the pressure of impact from the piping.
