The built-in check baffle can quickly seal the pipeline when the water ring pump stops, preventing gas and accumulated water in the pipeline from flowing back into the mine. According to the gas flow direction, in the suction pipeline, the water backflow and gas backflow prevention device is installed behind the slag remover and in front of the flame arrester. In the exhaust pipeline, this device is installed at the last position of the three-proof device, and it is the last three-proof device. Installation method: When installing this device, remember that the check baffle must be vertically downward so that it can tightly cover the pipe mouth by its own weight without external force. The drain valve should be at the bottom of the device. If conditions allow, connect a drainage pipeline under the drain valve to lead the discharged water into the drainage pool.
