Problems solved by technology

In addition, when the sealing performance of the gas one-way valve is degraded, the gas one-way valve needs to be replaced or repaired, but in the process of replacement or maintenance, the valve core of the gas one-way valve will have to be disassembled , so it will inevitably lead to the leakage of gas

Abstract

The invention discloses a gas one-way valve. The gas one-way valve comprises a valve body, a valve element, an elastic adjusting part and an elastic part, the valve body comprises a valve main body, the valve main body is provided with a mounting part and an air guide part, the mounting part is provided with a mounting channel and a mounting opening communicating with the mounting channel, an airguide channel is formed in the air guide part, an air guide port is formed in the air guide channel, the air guide channel is in abut joint with an air storage tank, the section diameter of the mounting channel is larger than that of the air guide channel, the air guide part and the mounting part form a step between the mounting channel and the air guide channel, the valve element is clamped to the step in a seal manner through the mounting opening, the elastic adjusting part forms a ventilation window, the elastic adjusting part is mounted in the air guide channel, the elastic part is mountedin the mounting channel in a compressed manner in a manner that one end of the elastic part is pressed against the valve element, and the other end of the elastic part is pressed against an elastic pressing-against part, the valve element is pressed on the step, and the air guide channel and the mounting channel are obstructed.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a gas one-way valve. Background technique [0002] Valve bodies are usually divided into fluid valves and gas valves according to different application fields. Both fluid valves and gas valves play an important role in various fields. In particular, gas check valves are widely used in the field of vehicles. [0003] For example, in some brake devices, a lot of pneumatic cylinders are used as the power mechanism of the brake. This will inevitably use a gas check valve. But a lot of existing gas one-way valves all adopt solenoid valves. On the one hand, this will lead to an increase in cost, and on the other hand, it will also increase the difficulty of design. [0004] As a gas one-way valve controlled by mechanical means, if it needs to be installed in the braking device of the vehicle, the gas valve must have good performance and low delay. Specifically, when the gas valve needs to venti...
