The performance of the pneumatic valve detection method. !

pneumatic valve performance testing method! ！

operator:

1, the open-close direction of pneumatic valve operation, all should be clockwise closing.

2, as the pneumatic valve in the pipeline, often artificial opening and closing, opening and closing of revolution shoulds not be too much, is the large diameter valves also should be 200 - 600 RPM.

3, in order to facilitate a person's opening and closing operation, in a plumber pressure condition, the appropriate open-close torque of 240 n - m。

4, pneumatic valve opening and closing operation side should be square tenon, standard and size, and face to the ground, so that people can be directly from the ground.

if, pneumatic valve buried deep, operating mechanism and the display panel from the ground 1 or higher. 5 m, long pole facilities shall be available, and fixed in mind, so that people from the face of the earth observation and operation. That is to say, the valve opening and closing operation in pipe network, unfavorable under operation.

performance detection:

1, a valve specifications and batch manufacturing, should entrust institutions to test the performance of the following:

( 1) The valve in a working pressure condition of opening and closing torque.

( 2) Under the working pressure condition, can guarantee strict continuous opening and closing the valve closed.

( 3) The flow resistance coefficient of valve in the pipeline under the condition of detection.

2, pneumatic valves should be tested before they go out:

( 1) Valve in open conditions, the body should be valve working pressure value of the internal pressure test.

( 2) The closing of the valve conditions, on both sides of the valve working pressure value respectively, no leakage; But the metal sealing butterfly valve, leakage nor a value greater than the related requirement.
