Technical Field

[0001] The utility model relates to the technical field of valve sleeve replacement, in particular to a valve sleeve which is convenient for replacing worn parts. Background Art

[0002] At present, the valve sleeve is a device of the valve execution part and is usually installed on the valve core. Its main functions are to reduce the opening and closing torque of the valve and reduce wear, so as to extend the service life of the valve. There are many types of valve sleeves, which can be divided into device sleeves, push sleeves, sealing sleeves, etc. according to their uses, or can be divided into metal valve sleeves, plastic valve sleeves, etc. according to materials.

[0003] In the Chinese utility model patent with the publication number of CN203022687U, a check valve sleeve is disclosed. In the above prior art, although the check valve sleeve has a simple structure, is easy to assemble and has a long service life, during the use of the valve, due to the scouring, corrosion of the fluid and frequent opening and closing operations, the valve sleeve and other easily worn parts often show wear phenomena. In order to keep the valve working normally and extend its service life, these worn parts need to be replaced regularly. Because the valve core is installed inside the valve sleeve, and the valve sleeve is not convenient to be directly opened on site, when the valve sleeve is replaced, the internal valve core will also be replaced together. However, with the protection of the valve sleeve, the valve core is not damaged, and the recovery of the undamaged valve core will cause waste. Therefore, it is necessary to design a valve sleeve that can directly retain the valve core for continued use when replacing the worn valve sleeve. Summary of the Utility Model

[0004] In order to solve the technical problem that when the valve sleeve is worn and replaced, the internal valve core will be directly replaced together, resulting in waste, the utility model provides a valve sleeve which is convenient for replacing worn parts.

Fixed plates are fixedly installed on one side of both the first half valve sleeve and the second half valve sleeve, and one side of the two fixed plates extends into the interior of the installation groove.

[0010] Through the above technical solution, the fixed plates cooperate with the installation groove to fix the positions of the first half valve sleeve and the second half valve sleeve, so that the two parts are combined together.

[0011] As a further improvement of the above solution, sealing rings are fixedly installed on both sides of the inner wall of the installation groove, and the outer surfaces and inner ring surfaces of the two fixed plates are in sealed fit with the adjacent sealing rings.

[0012] Through the above technical solution, the sealing rings can prevent water from passing through the fixed plates.

[0013] As a further improvement of the above solution, the fixing assembly includes a clamping plate provided on one side of the mounting plate and a pulling plate fixedly installed on one side of the clamping plate. One side of the clamping plate penetrates through the mounting plate and extends into the interior of the installation groove and penetrates through the adjacent fixed plate.

[0014] Through the above technical solution, the clamping plate and the fixed plate cooperate to completely fix the positions of the first half valve sleeve and the second half valve sleeve.

The limiting ring is adapted to the two baffles, and two limiting grooves adapted to the adjacent pulling plates are provided on the inner ring surface of the limiting ring.

[0016] Through the above technical solution, the limiting ring will fix the position of the clamping plate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a valve sleeve assembly and a fixing assembly, when it is necessary to replace a worn valve sleeve, only the fixing assembly needs to be removed, and the valve sleeve assembly can be taken off from the mounting plate. Installing a new valve sleeve assembly on the mounting plate and fixing it with the fixing assembly can complete the replacement of the valve sleeve. Such a setting can not only quickly replace the worn valve sleeve, but also retain the original valve core for continued use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0026] Please refer to Figures 1-4 , a valve sleeve for facilitating the replacement of worn parts in this embodiment includes a valve body 1. A valve core 2 is provided on one side of the valve body 1. A mounting plate 3 is fixedly sleeved on the valve core 2. A sealing ring is fixedly installed on one side of the mounting plate 3. A valve sleeve assembly that is sleeved on the valve core 2 and can be disassembled for replacement is provided on one side of the mounting plate 3. Fixing components for quickly installing and fixing the replaced valve sleeve assembly are provided on both sides of the valve sleeve assembly. The valve sleeve assembly includes a first half valve sleeve 401 provided on one side of the mounting plate 3 and a second half valve sleeve 402 provided on one side of the first half valve sleeve 401. The first half valve sleeve 401 is adapted to the second half valve sleeve 402. One end of the valve core 2 is located inside the first half valve sleeve 401 and the second half valve sleeve 402. An installation groove is formed on one side of the mounting plate 3. Fixing plates 6 are fixedly installed on one side of the first half valve sleeve 401 and the second half valve sleeve 402 respectively. One side of the two fixing plates 6 extends into the installation groove. Sealing rings 7 are fixedly installed on both sides of the inner wall of the installation groove. The outer surfaces and inner ring surfaces of the two fixing plates 6 are in sealed fit with the adjacent sealing rings 7. When the valve sleeve needs to be replaced, the fixing components are opened, and the valve sleeve assembly can be directly replaced. The internal valve core 2 will be retained for continued use. The fixing plates 6 cooperate with the installation groove to fix the positions of the first half valve sleeve 401 and the second half valve sleeve 402, so that the two parts are combined together.

[0027] Refer to Figures 1-4, the fixing component includes a clamping plate 501 arranged on one side of the mounting plate 3 and a pulling plate 502 fixedly installed on one side of the clamping plate 501. One side of the clamping plate 501 penetrates through the mounting plate 3 and extends into the installation groove to penetrate through the adjacent fixing plate 6. Both sides of the mounting plate 3 are fixedly installed with baffles 8 arranged in an "L" shape. A limit ring 9 is sleeved on the mounting plate 3, and the limit ring 9 is adapted to the two baffles 8. Two limiting grooves adapted to the adjacent pulling plates 502 are formed on the inner ring surface of the limit ring 9. The clamping plate 501 and the fixing plate 6 can cooperate to completely fix the positions of the first half valve sleeve 401 and the second half valve sleeve 402.

[0028] In the embodiment of the present application, the implementation principle of a valve sleeve that is convenient for replacing worn parts is as follows: When it is necessary to replace the worn valve sleeve, remove the original valve sleeve from the valve body 1, and then slide the limit ring 9 to cancel the fixing effect on the clamping plate 501. In this way, the clamping plate 501 can be removed from the mounting plate 3, and then the first half valve sleeve 401 and the second half valve sleeve 402 can be directly pulled off. Since the fixing plate 6 has lost the fixed effect, the valve core 2 is retained. Then, install the replaced first half valve sleeve 401 and second half valve sleeve 402 according to the above operations. When the installation is completed, use waterproof tape to wind the first half valve sleeve 401 and the second half valve sleeve 402 and then reinstall them on the valve body 1. Such a setting can not only quickly replace the worn valve sleeve but also retain the original valve core 2 for continued use.

[0029] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
