Embodiment 1

[0019] Example 1: Flange-like check valve

[0020] This embodiment includes a valve housing 2 and a terminal connector 1. The terminal connector 1 includes upper and lower flanges. The valve housing 2 is provided with an air filling nozzle 3, which inflates the valve housing 2 and uses gas to Eliminate water hammer and pipeline noise. The valve housing 2 is axially provided with a retractable air chamber holster 4, the top of the air chamber holster 4 is fixedly connected to the upper flange, and the bottom is connected to the bottom of the valve housing 2 to form an airtight air chamber, which is convenient for processing and manufacturing. Combined with the sealing ring, the processing cost can be reduced. The inner cavity of the valve housing 2 is provided with a double-cone valve core 7, which is equipped with a weight (dry sand) for adjusting the weight. The top and bottom are provided with positioning guide rods, and they are all connected to the guide holes on the end ...

Abstract

The invention discloses an air extinguishing hammer mute valve which comprises: a valve shell and end connection components. On the valve shell provided an air injection hole, by injecting air into the valve shell, the air-extinguishing hammer and combines the valve to eliminate the noise of water hammer and pipes. An air chamber holster is arranged axially on the valve shell; the top of the air chamber holster connects with the end connection components; the base connects with the bottom part of the valve shell. A balance screened is arranged on the inner wall of the air chamber holster; in the valve shell chamber cavity equipped a double-conical valve core which has weight for adjusting weight in it, and has positional guide bars on both the top and bottom ends, and they fit the guide holes on the end connection components.

Description

technical field [0001] The invention belongs to mechanical valve products, and relates to a general-type silencer valve for water hammer and noise caused by various reasons in a water (oil) pipeline system, in particular to a gas hammer silencer valve. Background technique [0002] In any high and long-distance (especially open-circuit water supply) water supply pipeline system where the pump automatically starts and stops (or stops the pump in an accident), or in an oil system with low viscosity, water hammer pressure is generated due to sudden pressure changes when the pump is stopped. Waves, coupled with the atmospheric pressure when the pipe outlet is cut off, will inevitably produce a strong water hammer phenomenon. Water hammer mostly occurs at the high-end outlet of water (oil) pipelines, and occurs in the form of water hammer pressure waves and vibrations, with high frequency and high instantaneous pressure. As a result, the pipelines, check valves and pipe brackets...
