Description

technical field [0001] The invention relates to a composite high-speed intake and exhaust valve. Background technique [0002] The composite high-speed intake and exhaust valve is a special intake and exhaust control device for water supply and drainage pipes, which is widely used in various water plants and pipe network systems in various water supply fields. Since the intake and exhaust valves are often installed at a higher position in the pipeline system, their purpose is to facilitate intake and exhaust. When a large amount of air is generated in the pipeline, the air will continue to flow to high places. The pipe is at a high place and is in an open state. A large amount of air will be blown into the bottom of the intake and exhaust valve from the pipe, and will be discharged from the exhaust port of the intake and exhaust valve after passing through the inner cavity of the valve. , because the pressure of the outside atmospheric pressure is higher than the pressure i...
