Mechanical adjustable water hammer eliminating device for non-negative-pressure equipment

Abstract

The invention discloses a mechanical adjustable water hammer eliminating device for non-negative-pressure equipment. The mechanical adjustable water hammer eliminating device comprises a base and a non-negative-pressure water supply unit, a non-negative pressure water supply unit is connected to the upper portion of the base, the base serves as a bearing foundation of the device, and one end of the water supply pipe is connected with a communicating pipe. The return valve is connected to one end of the communicating pipe, a gate valve is arranged on the communicating pipe, and a gas injection valve is connected to one side of the embedded pipe. According to the mechanical adjustable water hammer eliminating device for the non-negative-pressure equipment, the water hammer effect is eliminated by enabling impact to act on the piston disc and internal pressure gas to be in a balanced state, the internal pressure intensity is adjusted by adjusting the distance between the lower barrel body and the upper barrel body, and then the water hammer effects of different intensities can be conveniently coped with; the two sets of hollow pipes are inserted into the two sets of butt joint cylinders, so that the lower cylinder body is conveniently installed on the gate valve, the arc-shaped clamping plate moves upwards, so that the pipeline is conveniently supported, and the I-shaped rod is inserted into the limiting groove, so that the gate valve is conveniently installed above the communicating pipe.

Description

technical field [0001] The invention relates to the technical field of non-negative pressure water supply, in particular to a mechanically adjustable water hammer elimination device for non-negative pressure equipment. Background technique [0002] The non-negative pressure water supply equipment is a pressurized water supply unit, which is directly connected to the municipal water supply pipe network, and is connected in series with the residual pressure of the municipal pipe network to supply water to ensure that the pressure of the municipal pipe network is not less than the set protection pressure. Water supply equipment, when there is no negative pressure water supply equipment, encounter unexpected situations, such as the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, so it is necessary to use a water hammer elimination device, the existing water hammer elimination device There are still certain defects in use, su...
