Description

Technical Field

[0001] The present invention relates to the field of water supply and drainage, and particularly to a water hammer eliminator for water supply and drainage that is convenient for maintenance. Background Art

[0002] Water hammer eliminators play a crucial role in water supply and drainage systems. They are mainly used to reduce or eliminate the water hammer effect caused by the rapid closing of valves, the sudden stop of pumps, etc. This phenomenon can lead to the vibration and noise of the pipeline system, and in severe cases, it may even cause damage to the pipeline and its connectors. Therefore, the reasonable installation and use of water hammer eliminators in water supply and drainage systems can effectively protect the safe operation of the system and extend its service life.

[0003] Water hammer eliminators need to be durable. The aging of materials and seals will lead to a decline in performance. The repair and replacement of water hammer eliminators require the shutdown of water supply and drainage for operation, which is rather inconvenient. Summary of the Invention

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A water hammer eliminator for water supply and drainage that is convenient for maintenance, including a pipeline, a reducing pipe, a connecting flange, a water hammer transmission structure, a fixing ring, a water hammer elimination structure, a base, fixing parts, support columns, and a stabilizing cylinder. The front end of the pipeline is connected to the small end of the reducing pipe, the connecting flange is installed on the large end of the reducing pipe, the water hammer transmission structure is installed on the side end of the reducing pipe, the fixing ring is fixed to the rear part of the side end of the pipeline, the water hammer elimination structure is installed in front of the fixing ring, and the water hammer transmission structure is connected to the water hammer elimination structure. The base is installed on the lower side of the middle part of the pipeline, the fixing parts are distributed on the base, the support columns are installed on the top of the base, the stabilizing cylinder is fixed to the top of the support column, and the stabilizing cylinder surrounds the pipeline.

[0006] On the basis of the above technical solutions, the water hammer transmission structure includes a sliding cylinder, a cover plate, a sliding hole, a transmission column, a transmission pressure plate, a piston, a spring, a limiting hole, a support seat, a connecting column, and a limiting buckle. The front end of the sliding cylinder is respectively installed on the side end of the reducing pipe, the cover plate is installed on the rear end of the sliding cylinder, the sliding hole is opened in the middle of the cover plate, the transmission column is slidably connected to the sliding hole, the front end of the transmission pressure plate is connected to all transmission columns, the piston is installed inside the sliding cylinder, and the front end of the transmission column is connected to the piston. The spring is elastically connected to the rear end of the piston and the front end of the cover plate. The limiting hole is opened on the side end of the transmission pressure plate, the support seat is installed on the side end of the sliding cylinder, the connecting column is hinged to the support seat, and the limiting buckle is installed at the end of the connecting column and corresponds to the limiting hole.

[0007] On the basis of the above technical solution, the connecting column fixes the driving pressure plate to the front end of the cover plate either by connecting a limit buckle to a limit hole.

[0008] On the basis of the above technical solution, the water hammer elimination structure includes a connecting seat, a TPU sleeve, a cavity, a filling liquid, and an end plate. The connecting seat is fixed to the front end of the fixing ring. The TPU sleeve is installed at the front end of the connecting seat. The cavity is opened in the middle of the TPU sleeve. The filling liquid is filled in the cavity. The end plate is installed at the front end of the TPU sleeve and corresponds to the rear end of the driving pressure plate.

[0009] On the basis of the above technical solution, the driving pressure plate pushes the TPU sleeve through the end plate to extrude the cavity, causing a protruding deformation to contact the stabilizing cylinder for flexible support.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention divides the water hammer eliminator into a water hammer transmission structure and a water hammer elimination structure. The water hammer transmission structure directly connected to the pipeline removes the airtightness function, improves durability, reduces the influence of aging on it, reduces the replacement frequency, and exposes the water hammer elimination structure to the external connection pipeline. The replacement and repair of it do not require shutting down the water supply and drainage pipeline, solving the problem that the repair and replacement of the water hammer eliminator require shutting down the water supply and drainage for operation, which is rather inconvenient.

Detailed implementation mode

[0019] The present invention will be further elaborated in detail below in conjunction with the attached drawings and specific embodiments.

[0020] As Figures 1 to 7 shown, a water hammer eliminator for water supply and drainage that is convenient for maintenance includes a pipeline 1, a reducing pipe 2, a connecting flange 3, a water hammer transmission structure 4, a fixing ring 5, a water hammer elimination structure 6, a base 7, a fixing piece 8, a support column 9, and a stabilizing cylinder 10. The front end of the pipeline 1 is connected to the small end of the reducing pipe 2, the connecting flange 3 is installed on the large end of the reducing pipe 2, the water hammer transmission structure 4 is installed on the side end of the reducing pipe 2, the fixing ring 5 is fixed to the rear part of the side end of the pipeline 1, the water hammer elimination structure 6 is installed in front of the fixing ring 5, and the water hammer transmission structure 4 is connected to the water hammer elimination structure 6. The base 7 is installed on the lower side of the middle part of the pipeline 1, the fixing pieces 8 are distributed on the base 7, the support column 9 is installed on the top end of the base 7, and the stabilizing cylinder 10 is fixed to the top end of the support column 9 and surrounds the pipeline 1.

[0021] The water hammer transmission structure 4 includes a sliding cylinder 11, a cover plate 12, a sliding hole 13, a transmission column 14, a transmission pressure plate 15, a piston 16, a spring 17, a limiting hole 18, a support seat 19, a connecting column 20, and a limiting buckle 21. The front end of the sliding cylinder 11 is respectively installed on the side end of the reducing pipe 2, the cover plate 12 is installed on the rear end of the sliding cylinder 11, the sliding hole 13 is opened in the middle of the cover plate 12, the transmission column 14 is slidably connected to the sliding hole 13, the front end of the transmission pressure plate 15 is connected to all the transmission columns 14, the piston 16 is installed inside the sliding cylinder 11, and the front end of the transmission column 14 is connected to the piston 16. The spring 17 is elastically connected to the rear end of the piston 16 and the front end of the cover plate 12. The limiting hole 18 is opened on the side end of the transmission pressure plate 15, the support seat 19 is installed on the side end of the sliding cylinder 11, the connecting column 20 is hinged to the support seat 19, the limiting buckle 21 is installed at the end of the connecting column 20, and the limiting buckle 21 corresponds to the limiting hole 18.

[0022] The connecting column 20 fixes the transmission pressure plate 15 to the front end of the cover plate 12 by connecting the limiting hole 18 through the limiting buckle 21.

[0023] The water hammer elimination structure 6 includes a connecting seat 22, a TPU sleeve 23, a cavity 24, a filling liquid 25, and an end plate 26.

The above is a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, the changes, modifications, substitutions, and variations made to the implementation manners still fall within the protection scope of the present invention.
