Problems solved by technology

[0003] However, the existing water hammer eliminators have certain defects in use. When the fluid pressure in the pipeline is eliminated, the pressure in the cylinder of the water hammer eliminator is constantly increasing due to the extrusion pressure of the piston. No auxiliary device is installed. The inner wall of the water hammer eliminator is cracked or the cover falls off, causing the water hammer eliminator to be discarded as a whole, and the reliability is reduced. Moreover, the existing water hammer eliminator is only connected through the installation flange, which has low stability. If it is touched, it will affect the normal work of the water hammer eliminator

Abstract

The invention discloses a water hammer eliminator auxiliary device, comprising an electronic air pressure gauge and a mini air pump, wherein the electronic air pressure gauge and the mini air pump areboth fixedly mounted on a water hammer eliminator main body, the water hammer eliminator main body is provided with a strengthening mechanism, an electric pressure release valve is fixedly mounted atthe center of a seal cover, an air cavity is internally provided with a mechanical decompression mechanism, the mechanical decompression mechanism comprises a fixed frame, a guide bar and a spring, the bottom end of the water hammer eliminator main body is provided with a mounting flange, and a mounting hole is formed in the mounting flange. Air in the air cavity can be released, so that the usereliability of the water hammer eliminator is improved, a piston can be enabled to fully eliminate fluid pressure, the installation of the water hammer eliminator is more stable, the piston can be prevented from inclining to cause seal performance reduction when being pressed, and the air in the air cavity can be assisted to reset the piston.

Description

technical field [0001] The invention belongs to the technical field of water hammer eliminators, in particular to an auxiliary device for water hammer eliminators. Background technique [0002] The water hammer eliminator is a device used to eliminate the water hammer shock wave caused by various reasons in the pipeline and protect the pipeline and equipment from damage. It is suitable for all kinds of water supply and drainage systems such as industrial mines, enterprises, high-rise buildings, power stations, etc., using the expansion and contraction of the air in the upper chamber of the piston, so that the sudden shock wave is buffered and the strength is relieved, and the huge water hammer is avoided to the greatest extent. Equipment damage caused by impact. [0003] However, the existing water hammer eliminators have certain defects in use. When the fluid pressure in the pipeline is eliminated, the pressure in the cylinder of the water hammer eliminator is constantly i...
