The SCAR sewage composite exhaust valve is used in sewage, river water with mud and sand and other high points on the pipeline or places with closed air. SCAR Sewage Compound Exhaust Valve can clear the pipeline by removing the gas in the pipe to achieve normal operation.

The performance and advantages of SCAR sewage composite exhaust valve:
1. The floating ball is controlled at the lower part, so that the dirt can only be in the lower part of the valve body, and the dirt will not wrap around the upper exhaust port, and will not affect the sealing performance.
2. This product is an exhaust valve for special sewage pipeline engineering.
3. The floating ball is made of stainless steel, with long service life, safety and reliability.
4. It can eliminate the gas in the pipeline, reduce resistance and save energy.
5. When the pipeline is under negative pressure, it can quickly and automatically inhale to prevent the pipeline from rupturing.
The principle of SCAR sewage compound exhaust valve:
When the sewage in the pipe is in operation, the SCAR sewage composite exhaust valve flap stops at the lower part of the positioning frame to perform a large amount of exhaust. When the air is exhausted, the sewage enters the valve, the ball floats, and the drive flap is closed to stop the exhaust. . A small amount of gas is naturally generated in the pipe when it is in operation. These gases will be concentrated in the upper part of the pipe. To a considerable extent, the sewage in the valve drops, the float drops along the water, and the gas is discharged from the small holes. If there is a power outage or a pump shutdown, negative pressure will appear at any time when the water in the pipe is empty, the float will drop along the water, and the small hole will be opened to drive the big hole to provide a large amount of air to ensure the safety of the pipeline. The principle of the SCAR exhaust valve is the same as the CARX exhaust valve, except that the structure is slightly modified, and the lever mechanism is slightly improved, so that the float is controlled at the bottom, so that the dirt can only be in the lower part of the valve body and the dirt will not be wrapped around the upper exhaust port. , Will not affect the sealing performance. The SCAR sewage composite exhaust valve is an exhaust valve for a dedicated sewage pipeline project.
