How does the breathing valve work and what are its components?

Breathing valve is a common mechanical device used to control the flow direction of fluid or gas in a pipeline. It is composed of valve body, valve core, spring and seals. The working principle of the breathing valve is based on the effect of pressure difference. When the pressure difference reaches a certain level, the valve core will be opened or closed by the pressure.

The working principle of the breathing valve is usually as follows: when the pressure inside the pipeline is greater than the pressure of the external environment, the valve core will be closed by the pressure to prevent the reverse flow of fluid or gas; when the pressure inside the pipeline is less than the pressure of the external environment, the valve The core is exposed to pressure from the external environment and opens, allowing the flow of fluid or gas.

The breathing valve is composed of a valve body, a valve core, a spring and a seal.

Valve body: The valve body of the breathing valve is usually made of metal materials and has a certain degree of strength and corrosion resistance, ensuring the service life and reliability of the valve.

Valve core: The valve core is the key component of the breathing valve. It realizes the switch function by cooperating with the valve seat. The valve core is made of rubber or metal material and has good sealing and wear resistance.

Spring: The spring is the control component of the breathing valve. Its function is to provide the opening and closing force of the valve core so that the valve core can

It is enough to realize the switch function according to the change of pressure difference.

Seals: The seals of the breathing valve are made of rubber or metal materials to ensure the sealing performance of the valve and prevent the leakage of fluid or gas.
