Resistance to high pressure check pneumatic valve structure and installation method

When check pneumatic valve used in high pressure environment, how to install? Let's show you check of resistance to high pressure pneumatic valve structure and concrete installation methods.














a pneumatic valve, high pressure check pneumatic valve disc, pneumatic seat channel axis of rotation, the pneumatic valve inside channel into a streamlined, flow resistance is smaller than l type check pneumatic valve, suitable for low flow velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, high pressure check pneumatic valve sealing performance than lift check valve. Type pneumatic valve check points single type, double disc type and mostly type three, the three forms mainly by the pneumatic valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock.


2, high pressure check pneumatic valve pneumatic valve body along the vertical centerline sliding check pneumatic valve, internal thread check pneumatic valve can only be installed in horizontal pipe runs with the high pressure on small check pneumatic valve pneumatic valve can be used. Check the pneumatic valve pneumatic valve body shape as well as by the pneumatic valve ( To stop pneumatic valve general) Fluid resistance coefficient is larger, so it. High pressure check pneumatic valve structure similar to stop pneumatic valve, pneumatic valve and pneumatic disc same as by the pneumatic valve. Pneumatic valve upper part and lower part of the pneumatic valve cover processing has a guide sleeve, Jane Jane pneumatic disc guide can be freely within the pneumatic valve light guide Jane, when medium downstream, pneumatic disc by medium thrust open, when stop the flow of medium, landing on the hanging in the pneumatic pneumatic valve seat valve, prevent medium counter-current role.

3, high pressure check pneumatic valve is a pin on pneumatic pneumatic valve seat valve check pneumatic valve shaft rotation. Disc check pneumatic valve has simple structure and can only be installed in horizontal pipe runs, sealing is good.

4, high-pressure pneumatic disc check pneumatic valve is sliding along the center line of the pneumatic valve of pneumatic valve. Pipeline check pneumatic valve is a new kind of pneumatic valve and its small size, light in weight and good fabrication procedure, check the pneumatic valve is one of development direction. But fluid resistance coefficient than the swing check valve is slightly larger.

5, high pressure check pneumatic valve is cut off for boiler feed water and steam to use pneumatic valve, it can lift check pneumatic valve pneumatic valve and globe or Angle valve of comprehensive function.
