About the product

The operational principle of the exhaust valve assembly encompasses several key aspects:

1. **Basic Working Principle**: The exhaust valve functions based on the buoyancy effect exerted by water on a stainless steel float. As the water level within the valve rises, the float is lifted by the buoyant force until it makes contact with the sealing surface of the exhaust port. Upon reaching a specific pressure threshold, the valve automatically closes. Conversely, when the water level decreases, the float descends, enabling air to be injected into the pipeline via the exhaust port. This mechanism ensures that the exhaust valve can automatically open and close during pipeline operation, thereby maintaining the normal functioning of the system.

2. **Specific Working Process**: When gas overflows in the system, it accumulates at the highest point of the system and enters the valve chamber of the exhaust valve. As the volume of gas increases, so does the internal pressure. When the gas pressure exceeds the system pressure, it causes the water level in the chamber to drop, prompting the float to descend along with the water level. This action opens the exhaust port, allowing the gas to be expelled. Once all the gas has been discharged, the water level rises, lifting the float and closing the exhaust port. Similarly, during negative pressure conditions within the system, the water level in the valve chamber drops, opening the exhaust port to allow atmospheric pressure to enter the system, thereby preventing damage caused by negative pressure.

3. **Structural Characteristics**: The exhaust valve is typically installed at the highest point of the pipeline and features both large and small openings for efficient gas intake and exhaust. Its design effectively limits exhaust time, forming a pressurized air pocket that prevents pressure spikes caused by rapid water column closure (commonly referred to as the water hammer phenomenon). The valve boasts a simple yet robust structure, ensuring reliable performance, rapid response, high exhaust capacity, and fast operation. During routine operation, the exhaust valve automatically discharges residual gases through a small aperture, eliminating trapped air from the pipeline and ensuring the smooth operation of the network.

4. **Application Scenarios**: The exhaust valve finds extensive application in water treatment plants, water supply and drainage pipelines, deep well pump stations, and other related systems. It effectively addresses "water column breakage"-type water hammer issues at undulating points in the pipeline, safeguarding the integrity of the pipeline against such damage. Additionally, the valve ensures the safety of the pipeline network by promptly supplying air when vacuum conditions arise within the pipe.
