The working principle of oil and gas dynamic valve

（ ） Out of the oil and gas pneumatic valve and valve seat is precise matching parts, adopt high quality alloy steel manufacturing, the guide hole, upper and lower end face, and a hole through precision machining and grinding, after pair are not interchangeable.
（ ） Out of the oil and gas moving valve cone department was the axial seal cone of the pneumatic valve, pneumatic valve cone of sliding fit up the guiding role in the guide hole. Tail processing grooving, form the cross section, so that fuel through. The central oil and gas dynamic valve cylinder is reduced pressure zone, between it and seal cone formed a reduced pressure volume.
（ ） Pneumatic valve seat on the lower end face and plunger sleeve end face is a precision machining tight fit, it is stipulated by compression nut tightening torque to compaction. With compression nut a pneumatic seat between the thickness of the copper high pressure sealing washer. Out of the oil and gas valve compression nut and end on the shell and between low pressure seal gasket.
（ ） Dynamic valve in the oil and gas compression nut inner chamber equipped with slotted container, to reduce the inner cavity volume of the space, promote spraying stops quickly, to limit the dynamic valve lift of the largest oil and gas.
