The purpose of installing a breathing filter valve is to prevent which phenomenon from occurring in the pipeline?

The main purpose of installing a breathing filter valve is to prevent negative pressure and related safety hazards in the pipeline. Negative pressure means that the pressure in the pipeline is lower than the external atmospheric pressure. In the pipeline system, especially when the liquid is extracted or the flow rate of the liquid in the pipeline changes suddenly, negative pressure is easily formed in the pipeline. Negative pressure may cause the pipeline to deform, rupture, and even affect the normal operation of the entire system. Through its unique design and working principle, the breathing filter valve can automatically open when the pressure in the pipeline drops, allowing external air to enter the pipeline, thereby effectively balancing the pressure difference inside and outside the pipeline and preventing the generation of negative pressure.
The breathing filter valve has the function of automatically adjusting the pressure. When the pressure in the pipeline increases, the valve will automatically close to prevent excessive discharge of gas or liquid; when the pressure in the pipeline decreases, the valve will automatically open to introduce external air and restore the pressure balance in the pipeline. This automatic adjustment feature enables the breathing filter valve to respond quickly to pressure changes and ensure the stable operation of the pipeline system.
During the exhaust process, when the liquid in the pipe fills the pipeline, the breathing filter valve can automatically close to effectively prevent the liquid from leaking into the atmosphere. This not only protects the integrity of the pipeline system, but also avoids environmental pollution and waste of resources. By maintaining the balance of pressure in the pipeline, the breathing filter valve can reduce the energy loss caused by pressure fluctuations and improve the operating efficiency of the entire pipeline system.
Breathing filter valves are widely used in many fields due to their unique performance. For example, in oil storage tanks, fire water systems, chemical storage tanks and other occasions, breathing filter valves can quickly adjust the pressure to prevent negative pressure from affecting the pipeline system. In the oil and gas industry, it can prevent safety accidents caused by excessive gas pressure in the oil tank; in the chemical industry, it can control the pressure of chemical reaction liquids; in grain storage, it can prevent excessive carbon dioxide and water vapor from being generated by self-fermentation when grains are stored in closed containers.
The installation of breathing filter valves is to prevent negative pressure from being generated in the pipeline and the safety hazards caused by it. By automatically adjusting the pressure balance inside and outside the pipeline, the breathing filter valve can ensure the safe operation of the pipeline system, improve the operating efficiency of the system, and is widely used in many fields.
