Anti-theft intelligent air release valve

Abstract

The invention provides an air intake and release valve which prevents burglary and can effectively eliminate water hammer produced when air is discharged by a water supply pipeline. The air intake and release valve comprises a mass air intake and release valve, a water hammer prevention device and a trace air intake and release valve. The trace air intake and release valve is connected with a shell of the mass air intake and release valve; the water hammer prevention device is connected with the shell of the mass air intake and release valve; and the water hammer prevention device and the trace air intake and release valve are arranged in a protective cover of the circumstance of the shell of the mass air intake and release valve. The air intake and release valve has the advantages that: the air intake and release valve with the structure can limit the air release speed when the pipeline is filled with water and releases air quickly, so that an air bag is formed in the pipeline to buffer the compact of water on the pipeline; and external parts of a valve body are effectively prevented from being stolen because the external parts are embedded in the valve body and an attachment bolt is plugged; and an air layer is reserved above a main floating ball to prevent a sealing surface from being contacted with water, eliminate the phenomenon that water is leaked due to impurity blockage, and can effectively guarantee that the sealing surface is prevented from being frozen at an extremely low temperature, the main floating ball can leave the sealing surface and vacuum is not produced in the pipeline.

Description

technical field [0001] The invention relates to a valve structure, in particular to an anti-theft intelligent exhaust valve. Background technique [0002] On the one hand, most of the current intake and exhaust valves adopt the structure of adding trace intake and exhaust valves on the side of the main valve. The trace intake and exhaust valves are external, and the main float has no guiding device. There is no air partition above the float. This kind of structure is easy to cause the micro intake and exhaust valve to be stolen, so that the intake and exhaust valve loses the function of continuous intake and exhaust; the main float is easy to collide with the inner wall of the valve and damage the outer surface of the float; the main float can withstand the direct impact of high-speed airflow It is easy to be blown up to close the exhaust port, and the intake and exhaust valves lose a lot of exhaust functions; because there is no air partition above the main float, impuriti...

Problems solved by technology

This kind of structure is easy to cause the micro intake and exhaust valve to be stolen, so that the intake and exhaust valve loses the function of continuous intake and exhaust; the main float is easy to collide with the inner wall of the valve and damage the outer surface of the float; the main float can withstand the direct impact of high-speed airflow It is easy to be blown up to close the exhaust port, and the intake and exhaust valves lose a lot of exhaust functions; because there is no air partition above the main float, impurities in the water are easy to accumulate in the main exhaust port sealing ring, causing the exhaust port to leak. And when it is cold, the sealing ring and the main floating ball are bonded due to freezing, and the main floating ball cannot be separated from the sealing ring in time when the pipeline needs to be supplemented with air, resulting in a vacuum in the pipeline.

On the other hand, the current intake and exhaust valves have no anti-hammer device or the anti-hammer device cannot work. In the stage of water column bridging after the pipeline is quickly filled with water or the water column is separated in the pipeline, the water flow tends to impact the pipeline at high speed, causing damage to the pipeline and equipment. damage

Pipeline exhaust and air supply constant pressure are very important to water supply efficiency and pipeline service life. Water supply companies also know the importance of this type of product, but they cannot guarantee water supply and pipeline water due to many weaknesses of this type of product. safety, causing major safety hazards to the entire water supply industry
