Problems solved by technology

This kind of valve that uses atmospheric pressure to realize automatic air intake can solve the problem of normal discharge of water in the water tank, but it is found in use that this kind of valve has high requirements on the sealing of the water tank, and a slight deviation will affect the water tank. Discharge water is affected, it is very inconvenient to use

Abstract

The invention discloses an automatic air inlet valve assembly which comprises a valve body, a valve cover and a valve rod. The valve body is fixed on the side face of a water tank. The valve cover is fixed at one end, close to the inner side of the water tank, of the valve body and is made of rubber. The lower end of the valve cover is fixed on the valve body. The valve rod is fixed at the upper end of the valve cover. A floating block is fixed at the other end of the valve rod and floats on the water surface of the water tank. According to the automatic air inlet valve assembly, opening and closing of the valve cover is automatically controlled by buoyancy of the water inside the water tank, a requirement for sealing performance inside the water tank is not high, using is convenient, the structure is simple and manufacturing cost is low.

Description

technical field [0001] The invention relates to a valve, in particular to an automatic air intake valve assembly installed in a water tank, and belongs to the technical field of valves. Background technique [0002] In order to ensure that the water in the water tank can be discharged normally, an automatic air intake valve is generally installed on the water tank. Existing automatic air intake valves generally use atmospheric pressure to realize automatic control, for example, an automatic air intake valve in which a small ball is placed at one end of the valve body. The valve that uses atmospheric pressure to realize automatic air intake is usually when the water tank is drained. When the pressure inside the water tank is lower than the pressure outside the water tank, the air inlet of the valve will be pushed open, and the air outside the water tank will pass through the inlet. The air port enters the water tank; when the pressure inside the water tank is equal to the pr...
