Problems solved by technology

However, such a structure requires the one-way valve and the pressure relief valve to be installed on the airtight container separately, and the airtight container needs to reserve installation holes for different control valves, the installation times are many, and the sealing stability will also be affected
[0004] Later, some people added a pressure relief channel to the one-way valve, and the one-way valve controls the pressure relief operation together. The disadvantage of this structure is that the pressure relief channel is always closed when

Embodiment Construction

[0023] Please refer to Figure 1 to Figure 4 , a one-way valve with pressure relief protection function, including an inner valve sleeve 10 and a one-way valve core 20, the inner valve sleeve 10 is provided with an input hole 11, and the one-way valve core shaft 20 is axially movably arranged on the The inner valve sleeve 10 can move back and forth in the axial direction, and an elastic member 30 pushes the one-way valve core 20 to move axially upwards to close the input hole 11, and the gas or liquid with high pressure can be pushed inward from the outside. Opening the one-way valve core 20, the connection relationship and working principle of the inner valve sleeve 10, the one-way valve core shaft 20, and the elastic member 30 are prior art, and will not be described in detail. The one-way valve with pressure relief protection function also includes an outer valve sleeve 40 and a pressure relief valve core 50, the outer valve sleeve 40 sleeves the inner valve sleeve 10 and t...

Abstract

The invention discloses a one-way valve with a pressure relief protection function. The one-way valve comprises an inner valve sleeve and a one-way valve element. An input hole is formed in the innervalve sleeve, and one elastic part pushes the one-way valve element to move in the axial direction to close the input hole. The one-way valve further comprises an outer valve sleeve and a pressure relief valve element. The outer valve sleeve sleeves the inner valve sleeve, and the outer valve sleeve and the inner valve sleeve are connected together. A pressure relief hole is formed in the outer valve sleeve. The other elastic part pushes the pressure relief valve element to move in the axial direction to close the pressure relief hole. Thus, the one-way vale can achieve one-way feeding, more importantly, the pressure relief protection function is achieved in the feeding process, and the advantage of good safety is achieved. Moreover, during mounting, only one mounting hole needs to be reserved for a closing container, mounting is simple and convenient, and sealing stability of the closing container is effectively guaranteed.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve with pressure relief protection function. Background technique [0002] One-way valve, as the name suggests, is a switch that allows gas and liquid to flow in one direction. The one-way valve is arranged on the airtight container, and air or water is fed into the airtight container through the one-way valve, which can avoid air or water leakage of the airtight container during use. [0003] In order to improve the safety performance of the airtight container and prevent damage caused by excessive internal pressure of the airtight container, it is usually necessary to install a pressure relief valve on the airtight container to ensure that the pressure in the airtight container will not exceed the safe value. However, such a structure requires the one-way valve and the pressure relief valve to be installed on the airtight container respectively, and the airtight container needs ...
