Problems solved by technology

[0003] In the mine water pipeline, the harm of water hammer is huge. It is easy to cause strong vibration of the pipeline, the pipe joint is disconnected, and water is poured into the mine channel, causing flooding. The pipe is collapsed and damaged, causing the pump to reverse and damage the pump room or pipeline, affecting production and construction safety
Existing water hammer removal generally adopts pressure relief or one-way buffering to reduce the pressure of water hammer, the cost is high, and the effect of water hammer removal is average

Embodiment 1

[0048] like Figure 7 As shown, a method for eliminating water hammer in a mine drainage pipeline includes the following steps:

[0049] S1: Install the pipe body on both sides of the pipeline valve or at the water outlet of the pump through the flange. When the valve is closed or opened, fluid pressure will be formed in the pipeline;

[0050] S2: At the same time of opening or closing the valve, the servo motor is controlled by the set solenoid valve to drive the rotating plate to rotate, so that the rotating plate and the piston ring are on the same plane, which effectively blocks the water flow;

[0051] S3: Eliminate the positive fluid pressure by setting the elastic component to cooperate with the piston ring to form a buffer force;

[0052] S4: By setting buffer components and movable plates on the side wall of the pipe body to counteract the force of the water hammer on the side wall of the pipe body, the impact force of the fluid pressure is reduced.

[0053] In step...

Embodiment 2

[0059] like figure 1 , 3 , 4, a method for eliminating water hammer of mine drainage pipeline; including a pipe body 1 and a flange 2; the end positions of the pipe body 1 are provided with flanges 2, and the pipe Body 1 is connected to the water pipe;

[0060] The upper and lower sides of the pipe body 1 are connected with a box body 5, and the side of the box body 5 close to the pipe body 1 is provided with a movable plate 6, and the movable plate 6 is connected with a buffer assembly 7. The component 7 is connected with the inner wall of the box body 5;

[0061] The inner wall of the pipe body 1 is provided with a piston ring 3, the center of the piston ring 3 is provided with a rotating plate 10, the rotating plate 10 can rotate inside the piston ring 3, and one side of the piston ring 3 is connected with a plurality of elastic components 4, The other ends of the plurality of elastic components 4 are connected with a connecting block 8 , and the other end of the connect...

Embodiment 3

[0063] like figure 2 , 5 As shown, on the basis of the first embodiment, a hollow cavity 13 is provided between the inner wall and the outer wall of the piston ring 3, the piston ring 3 and the inner wall of the pipe body 1 are sealed and slidingly connected by a rubber ring, and the cavity The inside of 13 is provided with a servo motor 9, the output shaft of the servo motor 9 penetrates the inner wall of the piston ring 3, and the output shaft of the servo motor 9 is connected with a rotating shaft 11, the rotating shaft 11 is connected with the rotating plate 10, and the rotating shaft 11 is arranged in the rotation. The center position of the plate 10 drives the rotating plate 10 to rotate; the rotating plate 10 has a circular structure, and when the rotating plate 10 and the piston ring 3 are closed, it is used to block water flow.

[0064] The elastic components 4 are evenly and symmetrically distributed on one side of the piston ring 3. The elastic components 4 includ...

Abstract

The invention discloses a method for eliminating water hammer in a mine drainage pipeline, which includes the following steps: S1: install the pipe body on both sides of the pipeline valve through flanges or at the water outlet of the water pump, when the valve is closed or opened When the valve is closed, fluid pressure is formed in the pipeline; S2: while the valve is being opened or closed, the solenoid valve is used to control the servo motor to drive the rotating plate to rotate, so that the rotating plate and the piston ring are on the same plane, forming an effective water flow. Blocking; S3: Eliminate the positive fluid pressure by setting the elastic component to cooperate with the piston ring to form a buffer force; S4: By setting the buffer component and the movable plate on the side wall of the pipe body to offset the force of the water hammer on the side wall of the pipe body and reduce the fluid pressure impact force; through the joint action of the elastic component and the buffer component, the reaction force is repeatedly formed against the water hammer, eliminating the water hammer, reducing the damage of the water hammer to the mine pipe body and valves, ensuring normal production, and increasing the output of the mine pipeline. water safety.

Description

technical field [0001] The invention belongs to the field of pipeline water delivery, and in particular relates to a method for eliminating water hammer in mine drainage pipelines. Background technique [0002] The water hammer effect is an image. It refers to a serious water hammer caused by the water flow hitting the pipeline when the feed pump starts and stops. Since it is inside the water pipe, the inner wall of the pipe is smooth, and the water flows freely. When the open valve is suddenly closed or the feed pump stops, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve or the pump. Due to the smooth wall of the pipe, the subsequent water flow quickly reaches the maximum under the action of inertia, and produces a destructive effect. This is the "water hammer effect" in hydraulics, that is, positive water hammer. On the contrary, when the closed valve is suddenly opened or the feed pump is started, water hammer will also occur, wh...
