One-way valve and air conditioner

Abstract

The invention discloses a one-way valve and an air conditioner and relates to the technical field of the air conditioner. The technical problem that a one-way valve in the prior art easily howls can be solved. The one-way valve comprises a valve body, a guide post, a piston and a retaining component, wherein the guide post, the piston and the retaining component are arranged inside the valve body; the piston is arranged to slide along the guide post, so as to form an inflow opening between the piston and the valve body; the guide post is arranged to be fixedly connected with the valve body through the retaining component; the retaining component comprises a central part and at least two retaining bodies which extend out from the central part and are separated along the circumference direction; at least parts of the at least two retaining component bodies are inclined relative to the central part; an opening formed between the at least two retaining component bodies allows fluid which enters the valve body through the inflow opening to flow out of the one-way valve through the opening. The one-way valve and the air conditioner are used for improving the open area of the one-way valve, so as to reduce the noise of the one-way valve.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a one-way valve and an air conditioner provided with the one-way valve. Background technique [0002] Spring check valve is one of the important valves in air conditioning equipment. [0003] Such as figure 1 As shown, the structure of the existing spring check valve is mainly composed of a guide post 1, a spring 2, a gasket 3, a connecting pipe 4, a valve body 5, a piston 6, a backstop plate 7 and a valve seat 8, etc., wherein: backstop Plate 7 is also called retaining ring. The center of backstop plate 7 is a circular hole, and its main function is to support guide post 1, and the end effect of backstop plate 7 is to fix backstop plate 7 on valve body 5. There are several types of backstop plate structures such as three claws and four claws, and each part of the backstop plate is on a plane. [0004] The applicant found that: the prior art has at least the followin...

AI Technical Summary

Problems solved by technology

[0005] The existing spring-type check valve often produces whistling sound during use, and the sound is sharp. Those skilled in the art have not found the reason for the whistling sound. The applicant found that the reason is one-way The flow area of ​​the check plate inside the valve is too small, and the flow rate of the refrigerant is too high, resulting in eddy current and resonance
