Novel and simple water-hammer eliminating device

Abstract

The invention provides a novel and simple water-hammer eliminating device. The device comprises a water conveying pipe, a pipe valve and a protection box arranged on the pipe. A penetrating hole is formed between the protection box and the pipe and arranged in a water inlet of the pipe valve. A pressure operated valve is arranged in the penetrating hole and opened and closed through water pressure. The pressure operated valve is of a rectangular plate, and a pressure operated valve shaft or a hole allowing a valve through shaft to penetrate through is formed in the two sides of the position atone third of the length of the pressure operated valve. The two ends of the pressure operated valve shaft or the through shaft are fixed into the protection box and perpendicular to the portion, corresponding to the pressure operated valve shaft or the through shaft, of lower end of the side wall of the pipe. Water flowing cyclically through an impeller exists in the protection box. The novel andsimple water-hammer eliminating device has the beneficial effects that the structure is simple, implanting is easy, the problems that in a pipe closed system, the water flowing velocity is suddenly dropped due to certain external reasons such as sudden closing of the valve, and water-hammers damage the pipe are solved, the service life of the pipe is prolonged, and the pipe materials are saved.

Description

technical field [0001] The invention belongs to the field of water hammer elimination devices, and in particular relates to a novel and simple water hammer elimination device. Background technique [0002] Water hammer is in the closed pipeline system, due to some external reasons such as sudden closure of the valve or sudden power failure, the flow rate of the water suddenly decreases. Hitting the pipe wall causes water hammer to be extremely destructive, often causing damage to pipes or valves. However, the existing water hammer elimination technology devices often have the problems of complex structure, cumbersome operation and high cost, and cannot be effectively popularized on a large scale. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a new type of simple water hammer elimination device, which can solve the problem of sudden increase of the flow rate of water in the pipeline due to external factors suc...

Problems solved by technology

[0003] The technical problem mainly solved by the present invention is to provide a new type of simple water hammer elimination device, which can solve the problem of sudden increase of the flow rate of water in the pipeline due to external factors such as sudden valve closure or power failure, and the sudden increase of pressure on the pipe wall to normal flow state. The problem that the pipeline or valve is damaged by more than dozens of times
