SCAR sewage compound exhaust valve

Principle of action

When the sewage in the pipe is in operation, the valve flap stops at the lower part of the positioning frame for a large amount of exhaust, when the air is discharged, the sewage enters the valve, the ball floats, the valve is driven to close, and the exhaust is stopped. The tube will naturally produce a small amount of gas in operation, these gases will be concentrated in the upper part of the tube, to a considerable extent, the sewage in the valve drops, the float ball drops along the water, and the gas is discharged from the hole. If there is a power failure, stop the pump, there is negative pressure at any time when the water flow in the pipe is empty, the float ball drops along the water, and the small hole is opened to drive the large hole for a large amount of gas to ensure the safety of the pipeline.
Note: The pressure of the exhaust valve can not be lower than 0.02Mpa during use. If it is lower than 0.02Mpa, the exhaust valve is prone to water leakage. Must be equipped with a valve for maintenance.
SCAR exhaust valve is the same principle as CARX exhaust valve, only the structure is slightly modified, and the lever mechanism is slightly improved, so that the float 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 wind around the upper exhaust port, which will not affect the sealing performance. The second product is the exhaust valve for the special sewage pipeline project.

Overall dimensions

I. Product introduction
The principle of SCAR sewage compound exhaust valve is the same as that of clear water compound exhaust valve, only the structure is slightly changed, that is, the valve body is lengthened, the lever mechanism is slightly modified, so that the dirt only accumulates in the lower part of the valve body, does not affect the exhaust and does not leak.
Second, the main use of the product
The sewage compound exhaust valve is used for the high point of the sewage pipe or the place where there is air closure, which is used to remove the gas in the sewage pipe and then dredge the pipeline, so that the pipeline works normally. If the valve is not installed, the pipeline will be closed, so that the sewage flow rate is blocked by air, and even interrupted. If there is negative pressure in the pipe at any time, it will cause pipeline vibration or rupture, and the exhaust and suction valve will quickly inhale air to prevent pipeline vibration or rupture.
Third, the main working principle of the product
The sewage compound exhaust valve is used for the high point of the sewage pipe or the place where there is air closure, which is used to remove the gas in the sewage pipe and then dredge the pipeline, so that the pipeline works normally. If the valve is not installed, the pipeline will be closed, so that the sewage flow rate is blocked by air, and even interrupted. If there is negative pressure in the pipe at any time, it will cause pipeline vibration or rupture, and the exhaust and suction valve will quickly inhale air to prevent pipeline vibration or rupture.
Fourth, the installation of products
1. The sewage exhaust valve should be installed vertically, the riser system should be at the high point, and the horizontal pipe system should be installed at the end;
2. Install buffer plug valve below the sewage exhaust valve: When the pipeline is filled with water, due to the high pressure of the pipeline, when the water flow reaches the opening of the pipeline, the pipeline pressure gathers at the bottom of the air valve. When the buffer plug valve is not installed, the excessive water flow pressure will damage the components inside the exhaust valve, and then occur such as leakage of the exhaust valve, no exhaust and other phenomena, especially the buffer plug valve must be installed below the exhaust valve of the high pressure pipeline;
