Water hammer effect eliminating device

Abstract

The invention relates to a water hammer effect eliminating device. The eliminating device is used for eliminating acting force in the whole circumferential direction by disturbing impact water flows through rotation of splitter plates; and the eliminating device is characterized in that a water inlet connecting pipe is connected with one end of a main pipe body, a water outlet connecting pipe is connected with the other end of the main pipe body, the outer diameter of the water inlet connecting pipe is smaller than that of the main pipe body, the outer diameter of the water outlet connecting pipe is smaller than that of the main pipe body, the pipe wall of the main pipe body arches outwards to form a ring sleeve, a rotor ring is sleeved with the ring sleeve, gear teeth are arranged on theouter side face of the rotor ring, clamping blocks are arranged on the inner wall of the ring sleeve, clamping grooves are formed in the positions, corresponding to the clamping blocks, of the rotor ring, the inner side of the rotor ring is exposed out of the ring sleeve, the two sets of splitter plates are arranged on the rotor ring and located on the two sides of the rotor ring, the widths of the splitter plates are gradually reduced from outside to inside of the main pipe body, the splitter plates are attached to the inner wall of the main pipe body, and one end of a pressure relief cylinder is arranged on the main pipe body and close to the other end of the main pipe body.

Description

technical field [0001] The invention relates to a device for eliminating water hammer effect, which relates to a device for eliminating water hammer effect in pipelines, and belongs to the field of water conservancy engineering. In particular, it relates to an elimination device for disturbing the impacting water flow through the rotation of the diverter plate to eliminate the force in the entire circumferential direction. Background technique [0002] The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, mainly because the valve will generate a pressure. This is the so-called "water hammer effect" in hydraulics. In the prior art, a piston buffer mechanism is set on the side of the pipe close to the valve to impact against the surrounding pipe walls. However, due to the limited arrangement and nu...

[0002] The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and the pipe wall, mainly because the valve will generate a pressure. This is the so-called "water hammer effect" in hydraulics. In the prior art, a piston buffer mechanism is set on the side of the valve pipe to impact against the surrounding pipe walls. However, due to the limited arrangement and number of pistons, it is impossible to wrap and decompress the entire circumferential surface of the pipeline, resulting in slow buffering efficiency for water hammer force and unsatisfactory decompression effect.

[0003] The notification number CN110440089A discloses a water hammer elimination device, which includes a water pipe, a first water hammer elimination mechanism and an auxiliary mechanism. The left and right ends of the water pipe are respectively provided with a water inlet and a water outlet. The first water hammer elimination mechanism is set On the water pipe, a first round pipe is vertically provided on the water pipe, and the first round pipe communicates with the water pipe. The end of the first round pipe far away from the water pipe is provided with a first sealing plate. A first piston is slidably arranged, and the first piston is in sealing connection with the first round tube. A first air chamber is formed between the first piston, the first round tube and the sealing plate. The auxiliary mechanism can assist the first The water hammer elimination mechanism eliminates the water hammer shock in the water pipe. The piston elimination mechanism of this device cannot form the elimination effect of the water hammer force on the circular circumference of the pipeline, and the protection efficiency and performance are poor.
