Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, in particular to an intelligent exhaust valve. Background Art

[0002] The exhaust valve is a special air 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 and drainage fields. The composite high-speed air intake and exhaust valve has both large-hole or small-hole air intake and exhaust functions. When the empty pipe is filled with water, the large exhaust hole automatically discharges the air in the pipe at a high speed to prevent the air in the pipe from forming an air bag and hindering the flow of water; when the pressurized water is running in the pipe, the air precipitated from the water produces air resistance due to pressure and temperature changes. At this time, the small hole will automatically discharge the gas in the air bag out of the pipe; when negative pressure occurs in the pipe, it can automatically intake air at a high speed to destroy the vacuum to prevent the pipeline from being unstable and damaged due to negative pressure. When the pipeline is emptied, it can automatically intake a large amount of air to speed up the water discharge and shorten the water outage time. It can also eliminate the damage to the pipeline caused by the water hammer caused by stopping the pump.

[0003] The existing exhaust valve structure, such as the patent owner: Quanzhou Huhang Valve Manufacturing Co., Ltd. applied for a utility model patent on December 4, 2017, the patent application number is 201721683265.1, the patent name is an exhaust valve with a buffer filter device, which specifically discloses a valve body, a float cover and a valve cover, the float cover is arranged in the valve body, the float cover is provided with a float and a lifting cover, the valve cover is connected to the lifting guide sleeve, the exhaust valve also includes a buffer filter device, the buffer filter device is a cylindrical body, the body has a bottom and a top, the top is provided with a drainage hole, a flange is provided along the circumference of the bottom, the bottom is provided with a flange connected to the valve body by a thread, and the side wall of the body is provided with a plurality of small holes.

[0004] When in use, install the exhaust valve above the top of the pipe at the highest point in the longitudinal direction of the pipeline. When there is air in the pipe, it will first gather in the exhaust valve. When the empty pipe is filled with water, there is air in the pipe, and the float and the lifting cover are only affected by gravity without buoyancy, so both fall to the buffer pad at the bottom of the float cover; under the action of water pressure, the air in the pipe is discharged to the atmosphere at high speed through the window of the float cover and the exhaust hole of the valve cover; when the air in the pipe is discharged, the water in the pipe enters the valve cavity from the lower part of the valve body, at this time the float and the lifting cover float up quickly, the lifting cover presses against the valve hole seal, the exhaust valve automatically closes to stop exhausting, and no water is leaked; when the small hole is exhausted during normal operation, the air dissolved in the water will be discharged due to the pressure fluctuation in the pipe. The gas will gradually precipitate and accumulate in the exhaust valve cavity at the top of the pipe, forming a pressurized air bag in the exhaust valve. As the air bag grows larger, the water level in the valve drops. When the water level drops to a point where the buoyancy is less than the weight of the float, the float falls due to gravity, opening the small exhaust port on the top and automatically exhausting the gas from the small hole. When the gas is exhausted, the air bag disappears, the water level rises, the float rises again, and the small exhaust port is closed, thus forming intermittent automatic exhaust from the small hole. When a vacuum is generated in the pipe, the float and the lifting cover fall rapidly at the same time, and a large amount of air is added to destroy the vacuum in the pipe, thereby ensuring the safety of the pipe network.

[0005] However, since most exhaust valves are installed outdoors or even on remote hillsides or in underground wells, it brings great trouble to equipment maintenance. Utility Model Content
