Embodiment 1

[0026] Such as figure 1 and figure 2 A water hammer elimination tank is shown, the water hammer elimination tank includes a tank body 1 and a connecting pipe 2, the tank body 1 includes an outer shell 11 and an expandable liner 12 arranged in the outer shell 11, and the outer shell 11 is provided with Inflatable valve 111 and pressure relief valve 112, the opening of the expandable liner 12 is concentrically sleeved in the opening of the shell 11, the opening of the expandable liner 12 is in sealing communication with one end of the connecting pipe 2 and the end of the connecting pipe 2 is sealed The opening of the shell 11 is pre-filled with gas between the shell 11 and the expandable liner 12, and the other end of the connecting pipe 2 communicates with the main water pipe 5. The material of the expandable liner 12 is preferably rubber, and the air pipe of the air compressor Air pressure is charged into the tank body 1 through the inflation valve 111, and when the air pres...

Embodiment 2

[0039]This embodiment is basically the same as Embodiment 1, the difference is that the water hammer elimination tank also includes a control system 3 and an air supply mechanism 4, the control system 3 includes a controller 31 and an operation panel 32, and the air supply mechanism 4 includes an air Compressor 41, air pipe 42 and solenoid valve 43, one end of air pipe 42 is connected to the air outlet of air compressor 41, the other end of air pipe 42 is connected to the inflation valve 111, and solenoid valve 43 is installed on air pipe 42 , the air compressor 41 and the liquid level detection device 15 are respectively connected to the controller 31, there will be a small amount of gas leakage in the tank body 1 for about 3 months, the air pressure value will decrease, and the decrease in the air pressure value will cause the water pressure to decrease. If the air pressure is greater than the air pressure, the main water pipe fills the expandable inner tank 12 with water, ca...

Abstract

The invention discloses a water hammer eliminating tank and a water hammer eliminating method. The water hammer eliminating tank comprises a tank body and a connecting pipe, wherein the tank body comprises a shell and an inflatable inner container arranged in the shell, a gas filling valve and a pressure release valve are arranged on the shell, and an opening of the inner container is concentrically arranged in an opening of the shell in a sleeved mode; an opening of the inflatable inner container communicates with one end of the connecting pipe in a sealed mode, and one end of the connectingpipe seals the opening of the shell; and gas is pre-filled between the shell and the inflatable inner container, and the other end of the connecting pipe communicates with a main water pipe. Accordingto the water hammer eliminating tank and the water hammer eliminating method, the effect that after a water pump stops running or a valve is closed suddenly due to the water station accident outage,the water pump, the main water pipe and the connecting part are intact is realized.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water hammer elimination tank and a water hammer elimination method. Background technique [0002] When a pump stop water hammer accident occurs in the pump station, it will cause "running of water" and water stoppage, and in severe cases, the pump room will be flooded, so that the factory will be forced to stop production, damage the infrastructure, and some equipment will be damaged by the water hammer. The damage caused casualties. The water hammer effect refers to a serious water shock caused by the water flow hitting the pipeline when the feed water pump starts and stops. Because the inner wall of the water pipe is smooth and the water flows freely, when the valve is opened Sudden shutdown or stop of the water supply pump, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve or the pump. Because the pipe wall is smooth, the subse...
