Installation knowledge of exhaust valve

1. The exhaust valve must be installed vertically, that is, bixu should ensure that its internal buoy is in a vertical state, so as not to affect the exhaust;

2. When the exhaust valve is installed, it is best to install it together with the block valve, so that when it is necessary to remove the exhaust valve for maintenance, the system can ensure airtight, water will not drain;

3. The exhaust valve is generally installed at the zui high point of the system, which is conducive to improving the exhaust efficiency.

Performance requirements of exhaust valve:

A. The exhaust valve shall have a large discharge capacity, so that rapid exhaust can be restored to normal water supply capacity in a very short time when the pipe is filled with water.

B. When the exhaust valve is under negative pressure in the pipe, the piston should be able to open quickly and rapidly inhale a large amount of external air to ensure that the pipeline will not be damaged by negative pressure.And under working pressure, it can discharge the accumulated trace air in the pipeline.

C. The exhaust valve shall have a relatively high air closing pressure. Within a relatively short time before the piston closes, it shall have sufficient capacity to exhaust the air in the pipeline and improve the water delivery efficiency.
