Quick exhaust valves are important devices in pipelines of water delivery systems. The quick exhaust valve is installed at a high position or a place with closed air in the water conveying system. When a large amount of gas is generated in the pipeline, the quick exhaust valve can quickly exhaust the air in the pipeline, and when a small amount of gas is generated in the pipeline, the quick exhaust valve can timely exhaust the small amount of gas in the pipeline, so that the gas resistance generated in the pipeline is prevented, and the water delivery efficiency is improved; when negative pressure is generated in the pipeline, the quick exhaust valve can suck air quickly, and the pipeline is prevented from being damaged due to vibration.
The quick exhaust valve is a combined valve of a gravity type one-way valve and a ball float valve. The quick exhaust valve is provided with a cylindrical valve body, the lower end of the valve body is provided with an inlet, the upper end of the valve body is provided with an outlet, a floating ball barrel is arranged in the valve body, the lower part of the floating ball barrel is provided with a water inlet, a floating ball is arranged in the floating ball barrel, a valve core is arranged above the floating ball, a valve body sealing ring matched with the valve core is arranged in the valve body, a guide ring on the axis of the valve body is arranged in the outlet of the valve body, a circular tube-shaped guide rod inserted in the guide ring is arranged above the valve core.
The valve body, the valve body sealing ring and the valve core of the quick exhaust valve form an air suction one-way valve, the floating ball and the valve core form a large-displacement float valve, and the floating ball and the circular tube-shaped guide rod with the pipe orifice sealing ring embedded in the pipe orifice form a small-displacement float valve.
The problems of the traditional exhaust valve are as follows: the exhaust valve is arranged at a position higher than or closed to the delivery system, and passively waits for gas to enter the exhaust valve, but a plurality of free bubbles exist in the water delivery system, are attached to the inner wall of the water delivery system due to small volume, are not converged into a strand of gas, and cannot enter the exhaust valve automatically. Or because reasons such as special construction, bend of conveying system pipeline have locally formed and hindered gas and have shoved to the obstacle structure of discharge valve for gaseous detention, if set up all discharge valves in every obstacle structure department, although solved the exhaust problem, improved installation cost, need carry out a large amount of transformation to water pipe moreover.
