FREE-VALVEbrandCARX-type
composite air-exhaust valve body is barrel-shaped, and includes
floats, stems and disc. The valves are used at the highest point on
the pipe or where there is a closed gas and at the pump outlet for
removing gas from the pipe, so that the pipe is working properly.
If the air-exhaust valve is not installed, the pipeline at any time
gas resistance, so that the pipeline water capacity can not meet
the design requirements. When negative pressure is generated in the
pipeline, the valve is quickly drawn into the outside air to
prevent damage to the pipeline due to negative
pressure.
Working principle :
The composite air-exhaust valve is provided
with two holes, one big and the other small, the big hole and the
diameter is basically equal, The pipeline will have a lot of gas
discharged to the outside when the water is supplied in the first
time, these gases are discharged from the big hole.When the air is
exhausted, the float ball is floated in the valve when there is
water in the body cavity, the drive plug disc to the closed
position, the large hole to stop a large amount of exhaust.When the
water is normally transported in the pipe, if there is a small
amount of air gathered in the valve to a considerable extent, the
water level in the valve drops, the floating ball drops, and the
air is discharged from the small hole.When negative pressure is
generated in the pipe.

Installation diagram
During the use of the air-exhaust valve, the
medium pressure should not be less than 0.02mpa. If it is less than
0.02mpa, the air-exhaust valve is easy to leak, and the valve must
be equipped with a cut-off valve for maintenance.
