Abstract

The invention discloses a device for keeping a water body in an air pressure tank fresh. The device comprises the air pressure tank and a bidirectional check valve; the air pressure tank comprises a tank body and an airbag; a water chamber is formed in the tank body, and the airbag is arranged in the tank body; an air chamber is formed in the airbag, and an inflation inlet communicating with the air chamber is formed in the tank body; a water in-out opening communicating with the water chamber is formed in the tank body; the bidirectional check valve comprises a main valve body; one end of themain valve body communicates with the water in-out opening, and the other end of the main valve body is used for communicating with a water supply pipe network; and a water inlet cavity and a water outlet cavity are formed in the main valve body, a water inlet cavity check valve is arranged in the water inlet cavity, and a water outlet check valve is arranged in the water outlet cavity. It is guaranteed that water in the air pressure tank can be quickly replaced in the using process, and the water body is kept fresh.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a device for keeping water in an air pressure tank fresh. Background technique [0002] The secondary water supply equipment has a variety of structures and control methods, and most of them adopt the form of "water pump unit + frequency conversion electric control cabinet" in structure. Generally speaking, unlike the regular and quantitative supply of domestic water, the change curve of domestic water consumption is relatively large, and has obvious time characteristics. Therefore, domestic water supply equipment should have the concept of "more water, more power consumption; less water, less power consumption" Energy saving features. [0003] The pressure tank is the prerequisite for the water pump to go to sleep. Using the extremely small compressibility of water, the water is stored in the tank with an external force. The gas is compressed and the pressure inc...
