Important Product introduction:The check valve is a kind of valve that supports the medium's own flow, and the active opening and closing valve clack is used to prevent the reverse flow of the medium. There are four basic types of check valve for valve supply network lining: HG41 flange connection longitudinal lift check valve and HG42 lift vertical check valve, HG44 vertical check valve and HG76 swing check valve.
Application range:
Lift type check valve only permits fluorine media to flow in one direction, and stop the flow in the opposite direction, usually the fluorine valve is active work, pressure flow in one direction, the valve opens, fluid flow has the opposite direction when the liquid pressure and the weight of the valve, and the role of the valve in the valve, thereby cutting off flow. The break valve is the type of valve, which includes lift check valve, swing check valve, clip type check valve, etc..
1 , swing check valve
Important models: H44F46 and H74F46 fully lined single swing series and H76F46 type double disc swing series, structure of them is: the valve is the valve seat on the (PIN) special groove shaft, embedded between the valve body and the valve cover is formed within the opening and closing, naive, reliable sealing, in addition the characteristics of H72F46, and the H76F46 type check valve is: in addition to valve body, valve, a reset spring is also full of lining fluorine plastic corrosion resistant spring, reasonable design, the valve has sufficient sealing pressure can also in the low pressure area, ensure the reliability of the valve in the low pressure seal.
2. Vertical check valve
Important models are fully lined H40F46, H42F46 and H72F46 vertical vertical check valves, in which H40F46 is a new type of structure, the valve is hemispherical, and they are characterized by lining valve along the valve path axis lifting activities.
3 , lifting check valve
Important models are: full lining H41F46 longitudinal lift check valve, its structure is characterized by: fluorine valve plate perpendicular to the valve inlet and outlet axis for lifting activities.
