For check valve use.
Boring cover 22 in extension tube 1 is opened, ball valve is mounted in pipeline, need to be passed through in advance by the fluid of ball valve
The filtering of sieve plate 28 is just negotiable, can adjust fluid flow in pipeline by rotational handle 13 to rotational valve core 9 to reach
Effect, if the pressure of fluids within pipes is excessive, can wash screen pack 28 open, so that a part of fluid is not required to by screen pack
28 is just negotiable, can effectively prevent impacting screen pack 28 in the case where pipe fluid pressure is excessive, to make
At the damage of screen pack 28, the setting of screen pack 28 is flow backwards prevented also from liquid；
When rotational handle 13 closes spool 9, i.e. the opening that two pressure relief plugs 36 are located at two extension tubes 1, in pipeline
Fluid no longer circulate, if the Fluid pressure in pipeline increases suddenly, it will cause at valve pressure increase, fluid punching
Pressure relief plug 36 is hit, so that the second flexible connector 38 stretches, pressure relief plug 36 is opened, so that water flow passes through, is reduced at valve
Suffered pressure plays certain decompression function, and when manifold pressure decline, the second flexible connector 38 is restored,
Pressure relief plug 36 is kept in the center, and is fitted closely with firm plate 35, and the circulation of fluid is truncated at valve, so that valve again serves to
Seal the effect of pipeline.
