Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a quick assembly and disassembly structure for valves. Background Technology

[0002] A valve is a device used to control the flow of fluid. It is usually installed in pipelines or equipment. By adjusting the degree of valve opening and closing, it can realize the functions of starting, stopping, regulating flow or pressure of fluid. It is widely used in industrial, civil and commercial fields, such as chemical, petroleum, water supply and drainage, heating, ventilation and air conditioning, etc., and is an indispensable key component in fluid control systems.

[0003] A quick-release valve assembly is a mechanical structure specifically designed to simplify the valve disassembly and installation process.

This significantly improves work efficiency, reduces downtime, and ensures the sealing and reliability of the connection.

[0004] In the process of fixing existing valves and pipelines, alignment and adjustment are usually required. This is because the sealing performance and reliability of flange connections depend heavily on the precise alignment and uniform stress distribution between flanges. If the flanges are not properly aligned, the gaskets will not be able to achieve uniform pressure, resulting in poor sealing performance or even leakage. This alignment and adjustment process requires a certain amount of time and effort each time it is installed. Especially in scenarios with frequent disassembly and assembly, it will significantly increase the workload and time cost of installation and maintenance, making it difficult to meet the needs of rapid disassembly and assembly. Therefore, a rapid disassembly and assembly structure for valves is proposed to address the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A quick-assembly and disassembly structure for a valve includes a valve assembly 1, an external pipe 2, and an external flange 3. A fixing component 4 is installed on the outside of the valve assembly 1. An auxiliary component 5 is inserted into one end of the fixing component 4. A rubber sealing ring 6 is fixedly connected to the side of the external flange 3 near the valve assembly 1. The fixing component 4 includes a hexagonal plate 41. An extension ring 42 is fixedly connected to one end of the hexagonal plate 41. A limiting rotating ring 43 is fixedly connected to the outside of the extension ring 42. The limiting rotating ring 43 is rotatably connected to the inside of a limiting ring groove 44. The limiting ring groove 44 is opened inside a sleeve 45. A guide pin 46 is fixedly connected to one end of the sleeve 45. A fixing slot 47 is opened inside the guide pin 46. A threaded hole 48 is opened inside the hexagonal plate 41. The auxiliary component 5 includes a pressure plate 51. A straight groove 52 is opened inside the pressure plate 51. An insertion pressure plate 53 is fixedly connected inside the straight groove 52. The insertion pressure plate 53 is inserted into the inside of the fixing slot 47.

[0031] As a further implementation of this solution, valve assembly 1 includes valve body 11, with a threaded ring 12 fixed to the outside of valve body 11. Valve flanges 13 are fixedly connected to both the front and rear ends of valve body 11. Valve flanges 13 are sealed to the external flange 3 through rubber sealing rings 6. Hexagonal plate 41 is sleeved on the outside of valve body 11, and the inner side of threaded hole 48 is spirally connected to the outer side of threaded ring 12. Through the above arrangement, the hexagonal plate 41 can be easily rotated and moved by the spiral connection between valve body 11 and hexagonal plate 41, thereby achieving quick adjustment and fixation, further improving the installation efficiency and operation convenience of the device.

[0032] As a further implementation of this solution, the guide pin 46 slides inside the reserved hole of the valve flange 13, extends out of one end of the valve flange 13, is inserted into the reserved hole of the external flange 3, and extends out of the outer side of the external flange 3. Through the above settings, the design of the guide pin 46 allows it to slide and be positioned flexibly in the reserved hole, ensuring precise alignment between the valve flange 13 and the external flange 3, improving the uniformity of the seal, and reducing the risk of leakage.

[0033] As a further implementation of this solution, the inner side of the extension ring 42 is hollow, and a gap is provided between the extension ring 42 and the outer side of the valve body 11. The extension ring 42 extends to the inner side of the sleeve 45, and the sleeve 45 is fitted on the outer side of the extension ring 42. Through the above-mentioned arrangement, the gap is set to facilitate the friction generated by the contact between the extension ring 42 and the valve body 11, which causes the threaded ring 12 to wear. At the same time, the extension ring 42 extends into the sleeve 45, which can drive the sleeve 45 to move through the extension ring 42.

[0034] As a further implementation of this solution, one end of the sleeve 45 is configured with two sets of guide pins 46, one above the other. Each set of guide pins 46 has three pins. The upper set of fixing slots 47 penetrates the upper part of the guide pins 46. The number of guide pins 46 is the same as the number of fixing slots 47. A straight groove 52 penetrates one end of the pressure plate 51. The inner side of the straight groove 52 fits against the outer side of the guide pins 46. The insertion pressure plate 53 extends into the inside of the straight groove 52. With the above configuration, it is convenient for the two auxiliary components 5 to fit against the outside of each set of guide pins 46. Through the design of the insertion pressure plate 53 and the fixing slots 47, the guide pins 46 can drive the pressure plate 51 to squeeze the external flange 3, thereby achieving the sealing effect between the rubber sealing ring 6 and the external flange 3 and the valve flange 13. At the same time, this fixing method is convenient and quick.

[0035] Workflow: When fixing the valve assembly 1 to the external flange 3 of the external pipe 2, the guide pins 46 are all retracted into the reserved holes of the valve flange 13 beforehand. Align the reserved holes of the valve flange 13 with the reserved holes of the external flange 3. Then, rotate the hexagonal plate 41. Since the hexagonal plate 41 is screwed to the threaded ring 12 fixed to the valve body 11 through the threaded hole 48, the hexagonal plate 41 will move when it rotates. When the hexagonal plate 41 rotates, it drives the extension ring 42 and the limiting rotating ring 43 to rotate. The rotatable connection is inside the limiting ring groove 44, while the extending ring 42 rotates inside the sleeve 45. When the limiting rotating ring 43 moves, it will drive the sleeve 45 and the guide pin 46 to move. At this time, the guide pin 46 will move into the reserved hole inside the outer flange 3. One end of the guide pin 46 has an arc-shaped structure, which improves the convenience of inserting the guide pin 46 into the reserved hole inside the outer flange 3. After the guide pin 46 moves into the reserved hole inside the outer flange 3, it will align the valve flange 13 with the outer flange 3. When the sleeve 45 is fitted with the valve flange 13, the guide pin 46 extends out of the outer flange 3. At this point, align the straight groove 52 of the pressure plate 51 with the multiple guide pins 46, so that the insertion pressure plate 53 is inserted into the inner side of the fixing slot 47. Then, install the lower auxiliary component 5 in the same manner. At this point, the two pressure plates 51 are magnetically attracted and pressed tightly together. Then, rotate the hexagonal plate 41 according to the same principle, causing the hexagonal plate 41 to move the sleeve 45 and guide pin 46 in the opposite direction. As the pressure plate 51 moves in the direction of movement, when it is tightly pressed against the external flange 3, the external flange 3 and the valve flange 13 are pressed together by the pressure plate 51. At this time, the rubber sealing ring 6 will be tightly pressed against the valve flange 13, thereby achieving the functions of fixing and sealing. Based on the above principles, the device changes the traditional method of fixing with multiple bolts one by one. The fixing method of the device is not only convenient and labor-saving, but also ensures that the external flange 3 and the valve flange 13 can be aligned, which significantly improves the uniformity of sealing and improves the working stability of the valve assembly 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
