Technical Field

[0002] The exhaust well of a water supply pipe refers to an exhaust device installed in a water supply pipe. It is set at the high point of the pipe to discharge the air in the pipe to ensure the normal operation of the water supply pipe. If there is air in the water pipe and it is not removed, the water will form "air bags" in the pipe, causing poor water supply or even water outage. The function of the exhaust well is to remove the air in the pipe in time to ensure smooth water flow. The location of the exhaust well does not have to be directly above the water supply pipe, but needs to be set below the high point of the pipe and the branch pipe connection to facilitate the removal of gas accumulated in the pipe. It is usually set in a pump room or water tank room.

[0003] Municipal exhaust wells often need to be connected to branch pipes for use, but the connection method between the branch pipes and the three-way pipes of the exhaust wells in general technology is relatively cumbersome, which is not convenient for users to install and disassemble them and is not convenient for users to use.
