Device for eliminating water hammer effect

Abstract

The invention belongs to the technical field of valves, and particularly relates to a device for eliminating the water hammer effect. The device comprises a main circulating pipeline, connecting pipelines, a first switch and second switches, wherein the main circulating pipeline is fixedly connected with the first switch; at least one group of first auxiliary pipes and second auxiliary pipes are arranged at the peripheral outer side of the main circulating pipeline; one end of each connecting pipeline is connected with the corresponding second auxiliary pipe, and the other end of each connecting pipeline is connected with the corresponding first auxiliary pipe through the corresponding second switch; the included angle a between the axis of each first auxiliary pipe and the axis of the main circulating pipeline is an acute angle greater than 10 degrees; the included angle b between the axis of each second auxiliary pipe and the axis of the main circulating pipeline is an acute angle greater than 10 degrees; the included angle a is greater than the angle b; each connecting pipeline is divided into a first connecting pipe and an arc-shaped pipe; and one end of each first connecting pipe is connected with the corresponding arc-shaped pipe, the other end of each first connecting pipe is connected with the corresponding first auxiliary pipe through the corresponding second switch, and the other end of each arc-shaped pipe is connected with the corresponding second auxiliary pipe. Liquid in the main circulation pipeline is decelerated through multistage reverse flowing, and therefore the water hammer effect is effectively eliminated.

Description

Technical field[0001]The invention belongs to the technical field of valves, and particularly relates to a device for eliminating the water hammer effect.Background technique[0002]Water hammer effect (or water hammer) refers to water flowing in a long pipeline. If the valve downstream of the pipeline is quickly closed at this time, the flow of water has inertial momentum, so the inertial momentum of water continues to push forward , Causing the pressure in the pipe to rise rapidly, that is, the kinetic energy effect of the fluid suddenly or continuously stopping or turning under the flow. When it occurs at home, in addition to slowly destroying the pipeline, the noise will cause a lot of trouble, which makes people mistakenly think The noise is made by neighbors. Especially in the pipeline of high-rise buildings (such as the tenth floor to the first floor), the flow of the waterway and the head drop (the drop between the two ends of the pipeline), the greater the instantaneous flow ...

Problems solved by technology

Especially in the pipelines of high-rise buildings (such as the tenth floor to the first floor), the flow rate of the waterway and the water head drop (the drop between the two ends of the pipeline), the greater the instantaneous flow rate and the water head drop, the faster the flow velocity and the greater the inertial momentum of the relative ground water flow. Large, the huge pressure caused by the water hammer effect is even more amazing, and may cause damage to the equipment
