Background
The municipal water supply system has the advantages that the water quality standard is gradually improved, the water supply capacity is enhanced, no negative pressure water supply equipment is needed, the original pressure of a municipal pipe network is fully utilized, the water supply is superposed and pressurized, the occupied area is small, the energy is saved, the environment is protected, and a large amount of application is realized. However, the existing non-negative pressure compensation is mostly communicated with the atmosphere to eliminate negative pressure, and the working principle is as follows: the water inlet of the non-negative pressure tank is connected with a tap water pipe network, the water outlet is connected with a water pump until reaching a user, when tap water enters the non-negative pressure tank, the water level in the non-negative pressure tank gradually rises, and air in the non-negative pressure tank is automatically discharged through the non-negative pressure automatic exhaust valve, so that the interior of the non-negative pressure tank is communicated with the outside to form no pressure. When the water level in the non-negative pressure tank rises to a certain water level, the non-negative pressure valve closes the automatic exhaust valve after receiving a water level signal, so that the pressure in the non-negative pressure tank is slowly formed, the pressure in the non-negative pressure tank is gradually increased along with the continuous entering of water in the pipe network, and the water level in the non-negative pressure tank can be stabilized until the pressure in the non-negative pressure tank is balanced with the pressure in the water inlet pipe network. When the water consumption of the water pump is increased or the water consumption of the tap water pipe network is reduced, the air pressure of the non-negative pressure tank gradually expands, the water level gradually decreases, and when the water level is lower than the specified water level, the non-negative pressure valve receives a water level decrease signal, the automatic air inlet valve is opened, so that the vacuum is not formed in the non-negative pressure tank, and the suction stroke of the water pump is not formed.
The existing non-negative pressure water supply equipment is usually directly communicated with the atmosphere, so that negative pressure generated in the equipment is avoided, and tap water is easy to cause secondary pollution when contacting with air.
