Description
Technical Field
The utility model relates to the technical field of valves, in particular to improved generation discharge valve.
Background
The exhaust valve is an indispensable auxiliary element in a water supply pipeline system and is a device for timely exhausting gas in a pipeline out of the system. When the pipeline begins to feed water, the air in the pipeline is discharged from the large exhaust port of the exhaust valve, and the exhaust valve can improve the water delivery efficiency of the pipeline. When the pipe is filled with water, the floating ball in the exhaust valve floats to drive the plug head to close the exhaust port, and the exhaust valve can prevent water flow in the pipe from leaking. In the process of pipeline water delivery, a small amount of air is still accumulated in the exhaust valve, when the air is accumulated to a certain degree, the floating ball in the exhaust valve descends, and after the air is discharged from the small hole below the plug head of the exhaust valve, the floating ball floats to plug the small hole. When the water inlet is stopped in the pipe, the pipeline can generate negative pressure, and the plug can be quickly opened to suck air into the pipeline, so that the pipeline is prevented from being broken. Therefore, the exhaust valve has the important functions of improving the use efficiency of the pipeline, increasing the water passing section of the pipeline, reducing the energy consumption and protecting the safety of the pipeline, and is an essential valve in a water supply pipeline system in cities and towns. The exhaust valve on the market adopts the linkage of a lever and a floating ball to control the opening and closing of the exhaust valve, and the lever in the exhaust valve is easy to damage due to continuous movement, so that the exhaust valve needs to be regularly checked and maintained, the cost is wasted, and labor is greatly lost. While hindering normal operation of the water supply system. And the structure of the lever is complicated, and the manufacturing cost is high, is unfavorable for the push rod of the product. In addition, the cover at the air outlet of the exhaust valve can only prevent impurities from entering the exhaust valve from the upper end part, and cannot prevent the impurities from entering the exhaust valve from the left end and the right end, so that an exhaust channel is blocked, and the exhaust of the exhaust valve is not facilitated.
