Description

Technical Field

[0001] The invention relates to indoor pipelines, in particular to a pipeline water hammer elimination device. Background Art

[0002] During daily water use, the valve on the water pipe is suddenly opened and closed. Due to the inertia of the water flow, a water shock wave will be generated, forming a water hammer phenomenon, which can easily cause the hose to burst. Summary of the invention

[0003] The present invention aims to solve the above technical problems, thereby providing a pipeline water hammer elimination device to eliminate water hammer and increase the service life of the pipeline.

[0004] The present invention solves the technical problem and adopts the following technical solution: A pipeline water hammer elimination device comprises a pipeline, one end of which is provided with a standard water pipe joint. A water flow buffer tube is provided at one end of the standard water pipe joint of the pipeline. The water flow buffer tube is perpendicular to the pipeline, and the outer end of the water flow buffer tube is closed. A slider and a spring are installed in the water flow buffer tube from the inside to the outside in sequence. The slider is slidably and sealedly connected to the water flow buffer tube.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: 1) Eliminate water hammer. When the valve is suddenly opened and closed to generate water flow impact, the water flow impact force exerts pressure on the slider. The slider compresses the spring to withstand the water flow impact force. After the water flow impact is eliminated, the slider and spring components are reset; 2) Simple structure, practical and low cost.

[0006] Further, the optimization scheme of the present invention is: The pipeline is a hose.

[0007] A sealing ring is arranged on the outer circumferential surface of the sliding block.

[0008] The spring is a compression spring.

[0009] The lower end of the water flow buffer tube is detachably mounted with a thread plug.

[0010] The water flow buffer tube is a hard tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of an embodiment of the present invention; In the figure: pipeline 1; standard water pipe joint 2; water flow buffer tube 3; slider 4; spring 5; water 6. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0013] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0014] See also Figure 1 The present embodiment provides a pipeline water hammer elimination device, which is mainly composed of a pipeline 1, a standard water pipe joint 2, a water flow buffer tube 3, a slider 4 and a spring 5. The pipeline 1 is a hose, and a standard water pipe joint 2 is installed at the right end of the pipeline 1. The standard water pipe joint 2 is used to connect a faucet or other pipelines. The standard water pipe joint 2 can also be installed at the left end of the pipeline 1.

[0015] A water flow buffer tube 3 is installed at one end of the standard water pipe joint 2 of the pipeline 1. The water flow buffer tube 3 is a hard tube, which can be made of PP, PE or steel pipe. The axis of the water flow buffer tube 3 is perpendicular to the axis of the pipeline 1, and the lower end of the water flow buffer tube 3 is closed. A slider 4 and a spring 5 are installed in the water flow buffer tube 3 from the inside to the outside. The slider 4 is circular and is slidably connected to the water flow buffer tube 3. In order to prevent the water 6 of the pipeline 1 from entering the spring 5 side of the water flow buffer tube 3, the slider 4 and the water flow buffer tube 3 are sealed. The outer circumferential surface of the slider 4 is provided with an annular groove, and a sealing ring is installed in the annular groove. The sealing ring is sealed and slidably connected to the inner wall of the water flow buffer tube 3. The spring 5 is a compression spring, which absorbs the impact force of the water flow and provides a reset force for the slider 4.

[0016] In order to facilitate replacement and maintenance of the slider 4 and the spring 5 , a threaded plug is installed at the lower end of the water flow buffer tube 3 , and the threaded plug is sealed and connected to the water flow buffer tube 3 .

[0017] When the valve is suddenly opened and closed to generate water flow impact, the water flow impact force in the pipe 1 generates pressure on the pipe 1, and the water 6 compresses the slider 4 and the spring 5 to withstand the water flow impact force. After the water flow impact is eliminated, the slider 4 and the spring 5 components are reset.

[0018] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
