[0002] The descaling valve positioning and guiding device is constantly being innovated in production and application, continuously improving the technological content of the product and enhancing the overall performance of the valve by focusing on some technical details.

[0003] During the opening and closing process of conventional descaling valves, the valve stem undergoes bending and vibration, leading to wear and reducing the service life of the valve stem and related components. Over time, this deteriorates the valve's operational accuracy and stability, ultimately shortening its lifespan. Therefore, to address these issues, we need to design a positioning and guiding device for the descaling valve. Utility model content:

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Please see Figures 1-2 This utility model provides a positioning and guiding device for a descaling valve, comprising:

[0021] The valve body 1 has a plunger 3 inside its cavity and a valve stem 6 that is slidably connected to it. The valve body 1 has a valve cover 11 on its top and a bracket 12 on its top. The bracket 12 has a cylinder lower cover 13 on its top. A first copper sleeve 10 is fixedly connected to the valve cover 11 and a protective component is installed in the first copper sleeve 10. A second copper sleeve 14 is fixedly connected to the cylinder lower cover 13.

[0022] Specifically, this device, under the action of an air source, causes the valve stem 6 to move up and down within the inner cavity of the valve body 1, thereby controlling the valve on the valve body 1 and allowing it to open and close, thus facilitating the flow of water into the valve body 1. Simultaneously, because a first copper sleeve 10 is installed in the inner groove of the valve cover 11 and a second copper sleeve 14 is installed in the inner groove of the cylinder lower cover 13, the first copper sleeve 10 and the second copper sleeve 14 provide positioning and guidance for the valve stem 6 as it moves within the valve body 1, ensuring the concentricity and straightness of the valve stem 6 during operation. This prevents friction between the valve stem 6 and the inner wall of the valve body 1, thereby reducing deflection and vibration of the valve stem 6, lowering wear, and extending the service life of the valve stem 6 and related components. Furthermore, the protective components in the device prevent impurities in the medium from entering the sealing ring 15 during the movement of the valve stem 6, thus achieving the function of sludge removal and silt removal.

[0023] Please see Figures 1-2 The protective components include a retaining ring 8, a washer 9, and a sealing ring 15. The retaining ring 8 is fixedly connected to the bottom of the first copper sleeve 10, the washer 9 is fixedly connected to the top of the retaining ring 8, the washer 9 is located at the bottom of the first copper sleeve 10, and the sealing ring 15 is located in the first copper sleeve 10.

[0024] Specifically, the bottom of the first copper sleeve 10 is provided with a retaining ring 8, which can prevent impurities in the water medium from entering the sealing ring 15 during the movement of the valve stem 6, thereby achieving the function of removing sludge and clearing silt. At the same time, the gasket 9 can prevent impurities in the water from entering the sealing ring 15, further enhancing the sealing effect.

[0025] Please see Figures 1-2 A pressure plate 7 is fixedly connected to the top of the plunger 3, and the top of the pressure plate 7 is fixedly connected to the valve stem 6. A valve seat 2 is provided in the valve body 1, a bushing 4 is provided in the inner cavity of the valve body 1, and a pressure sleeve 5 is provided in the inner cavity of the valve body 1. The valve stem 6 is slidably connected to the first copper sleeve 10, and the valve stem 6 is slidably connected to the second copper sleeve 14.

[0026] Specifically, when the valve stem 6 moves up and down within the inner cavity of the valve body 1, the valve stem 6 can move the pressure plate 7, and simultaneously drive the plunger 3 to move within the valve body 1, thereby controlling the valve on the valve body 1, allowing the valve to open and close, thus facilitating the flow of water into the valve body 1. Furthermore, the sliding connection between the first copper sleeve 10 and the valve stem 6, and the sliding connection between the second copper sleeve 14 and the valve stem 6, provides positioning and guidance for the valve stem 6 as it moves within the valve body 1. This ensures the concentricity and straightness of the valve stem 6 as it moves up and down within the cylinder lower cover 13 and the valve cover 11, preventing friction between the valve stem 6 and the inner wall of the valve body 1. This reduces the deflection and vibration of the valve stem 6, lowers wear, and extends the service life of the valve stem 6 and related components.

[0027] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
