Air compensator

Abstract

The invention provides an air compensator, and belongs to the technical field of air conditioners. The air compensator solves the technical problem that due to the fact that the pressure inside a water tank is reduced along with the reduction of water and air in the sealed water tank in the prior art, a pump must be started frequently. The air compensator comprises a shell and an air inlet valve. The shell is internally provided with a sealed cavity which is internally provided with a bowl-shaped bag slice. The bag slice divides the cavity into an upper cavity and a lower cavity and is elastic, the outer side wall of the bag slice can be attached to the inner wall of the upper cavity, and the air inlet valve is fixedly arranged at the upper end of the shell and communicated with the upper cavity. The upper end of the shell is provided with a water tank opening communicated with the upper cavity and the outside, the water tank opening is provided with a one-way mechanism enabling air to flow out of the upper cavity and not to flow reversely, and the lower end of the shell is provided with a low-pressure suction port which can be communicated with the lower cavity. The compensator is connected with the water tank, the air content in the water tank can be increased in time to compensate for air pressure and water pressure in the water tank, and accordingly the time of starting the pump is reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners and relates to an air compensator. Background technique [0002] The closed water supply tank system is to set the water tank on the ground. When the pump fills the water tank with water, because the water tank is a closed container, the air inside is compressed at the same time. When water is used, the compressed air inside is used to generate pressure to supply water to high places. The water supply of the closed water supply tank has many advantages such as clean and hygienic, less water evaporation loss, and the installation location is different from that of the open water tank, which must be placed at a high place and subject to geographical limitations, so it is widely used. In the current closed water supply tank system, as the water tank supplies water to the outside, the air in the water tank is either dissolved in water or directly discharged with the water flow, which reduces ...

AI Technical Summary

Problems solved by technology

In the current closed water supply tank system, as the water tank supplies water to the outside, the air in the water tank is either dissolved in water or directly discharged with the water flow, which reduces the air in the water tank and further reduces the water pressure, which is likely to cause frequent starts of the pump and affect The service life of the pump is also not conducive to energy saving

In addition, the air in the water tank cannot be replaced, which will easily cause water deterioration
