2020-10-15
Wafer check valve flow pneumatic valve refers to rely on the media itself, and automatically open, her breath valve, used to prevent the backflow medium pneumatic valve, also known as non-return pneumatic valve, pneumatic valve, one-way flow pneumatic valve, pneumatic valve and back pressure.
Check pneumatic valve belongs to a kind of automatic pneumatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium.
Check the pneumatic valve can also be used to give the pressure could rise to more than the system pressure of the auxiliary system supply piping.
Check the pneumatic valve mainly can be divided into pneumatic valve, swing check
In accordance with the center of gravity rotating)
Pneumatic valve and lift check (
Move along the axis)
。
This kind of pneumatic valves shall generally be installed in the pipeline.
installation notice:
place line should be paid attention to make the wafer check through the direction of the pneumatic valve in line with the direction of flow; Installed in the line of vertically. For horizontal pipe, vertically wafer check valve pneumatic valve; Between the wafer check pneumatic valve and pneumatic valve using a telescopic tube, don't pneumatic valve is directly connected with the other; Within a radius of pneumatic valve plate in operation, to avoid joining pipe joint and obstruction; Wafer check valve pneumatic valve installation considerations do not behind or in front of the wafer check pneumatic valve installation a variable diameter pipe; Wafer check valve pneumatic valve installed near the elbow, attention should be paid to leave enough space;
in the export of pump installed pneumatic valve, wafer check out at least 6 times the diameter of the pneumatic valve space to ensure that the board finally by fluid.
the wafer lift check the function of the pneumatic valve is to prevent water backflow, wafer check valve pneumatic valve estimate is also one of the functions, only connection is clamp connection, using two flange connection to the clamp, bolted directly to the wafer check valve of pneumatic valve and pipe (both ends Flanged) Wear clip together.
