Working Principle: |
1. Swing check valve The main models are: all village H44F46 and H74F46 single rotary series and H76F46 double flap rotary series, their structural form: the valve are around the valve seat outside the (pin) axis of rotation, opening and closing, to prevent backflow of media. H44F46 and H74F46 on the back of the broad is characterized by: (pin) axis and the valve phase is designed to be a single unit, all the village of the (pin) axis of the FEP, I'm in the body and cover formed between a special groove, opening and closing flexible, reliable sealing. The special groove formed between the valve body and cover, opening and closing flexible, reliable sealing, in addition, H72F46 and H76F46 check valve is characterized by: in addition to the valve body, valve flap, reset poppet is also all lined with corrosion-resistant fluorine plastics, well-designed springs, so that the valve flap in the low-pressure area can also produce enough sealing pressure, to ensure that the valve sealing in the low-pressure area of the reliability of the valve.
2. Lift the vertical check valves The main models are all village H40F46 type, H42F46 and H71F46 open peak vertical on the check valve, which H40F46 is a new type of structure, the valve row for the hemispherical, they have a common feature is lined with oxygen rows along the tuning body access axis to do lifting movement.
3. Lift check valve The main models are: fully lined H41F46 through the lift check valve, its structure is characterized by: fluorine lined valve flap perpendicular to the broad body inlet and outlet axis of the lifting movement, that is, to achieve the valve opening and closing process. |
