[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 3 As shown, a valve installation structure according to one embodiment of this utility model includes a valve body 1, a first fixing pipe 2 installed on the valve body 1, and an adjusting pipe 3 slidably connected inside the first fixing pipe 2. Specifically, a fixing ring 31 is integrally formed on the adjusting pipe 3, and a first sliding groove 21 matching the fixing ring 31 is formed on the inner wall of the first fixing pipe 2, with the fixing ring 31 slidably connected within the first sliding groove 21. An adjusting component is provided on the first fixing pipe 2, which allows the adjusting pipe 3 to slide within the first fixing pipe 2, changing the overall length of the first fixing pipe 2 and the adjusting pipe 3 to meet installation requirements.

[0028] The adjusting assembly includes a bolt 26. A threaded hole 27 matching the bolt 26 is provided on the first fixed pipe 2. The bolt 26's threads engage within the threaded hole 27, and one end of the bolt 26 within the threaded hole 27 connects to a fixing ring 31. Specifically, by turning the bolt 26 clockwise, it gradually enters the threaded hole 27, pushing the fixing ring 31. This allows the adjusting pipe 3 to slide into the first fixed pipe 2, shortening the overall length of both pipes. When the distance between the two pipes is small, the valve can be installed smoothly using this method.

[0029] Because the fixed ring 31 is slidably connected within the first groove 21, leakage may occur. Furthermore, a slip ring 24 is slidably connected within the first groove 21, and a sealing ring 25 is provided on the end face of the slip ring 24 near the fixed ring 31. A cylinder 22 is welded to the wall of the first groove 21, and a spring 221 is welded to the bottom wall of the cylinder 22. A sliding post 23 is welded to the end of the spring 221 away from the cylinder 22, and the sliding post 23 is slidably connected within the cylinder 22. The end of the sliding post 23 away from the spring 221 is welded to the slip ring 24.

[0030] Specifically, the elastic force of spring 221 pushes sliding column 23, which in turn pushes slip ring 24. The squeezing force between slip ring 24 and fixed ring 31 causes sealing ring 25 on slip ring 24 to fit against fixed ring 31, thus achieving a sealing effect. Regardless of whether adjusting tube 3 slides inward or outward within the first fixed tube 2, under the elastic extension and contraction force of spring 221, slip ring 24 and fixed ring 31 can always squeeze sealing ring 25, ensuring the sealing effect of sealing ring 25.

[0031] In addition, a lubricating layer is provided on the groove wall of the first slide groove 21. When the fixing ring 31 slides in the first slide groove 21, it reduces the friction between the first slide groove 21 and the fixing ring 31, and prevents excessive friction between the first slide groove 21 and the fixing ring 31 from causing gaps between the first slide groove 21 and the fixing ring 31, resulting in poor sealing effect.

[0032] Preferably, the lubricating layer is a polytetrafluoroethylene (PTFE) layer. PTFE has excellent corrosion resistance, capable of withstanding corrosion from almost all strong acids, strong alkalis, strong oxidants, and organic solvents, and also exhibits excellent aging resistance and radiation resistance.

[0033] like Figure 1 and Figure 6 As shown, a second fixed pipe 4 is welded to the end of the regulating pipe 3 away from the first fixed pipe 2. A flange 41 is fixedly connected to the second fixed pipe 4, and multiple through holes 411 are opened on the flange 41. During installation, the connection between the valve and the pipeline is achieved through the flange 41.

[0034] Because the distance between bolt 26 and adjusting tube 3 is relatively short, and the wrench is generally L-shaped, the wrench will be restricted by adjusting tube 3 when tightening bolt 26. Furthermore, the through hole 411 and threaded hole 27 are matched. Specifically, when tightening bolt 26, the wrench with a socket is inserted and then passed through the through hole 411, allowing rotation of bolt 26. This way, the wrench will not be restricted by adjusting tube 3 when tightening bolt 26. Preferably, bolt 26 is a countersunk bolt to prevent the outer wall of adjusting tube 3 from obstructing the outer wall of the wrench.

[0035] In use, depending on the distance between the two pipes, turn bolt 26 counterclockwise or clockwise. As bolt 26 moves within threaded hole 27, it pushes or pulls retaining ring 31, causing retaining ring 31 to slide within first fixed pipe 2. When the overall length of first fixed pipe 2 and regulating pipe 3 matches the distance between the two pipes, the valve is installed on the pipes via flange 41. This ensures smooth valve installation regardless of whether the distance between the two pipes is too large or too small.

[0036] Compared with the prior art, the valve installation structure of this utility model can make up for the errors in the previous process, thereby ensuring the installation progress, improving the installation efficiency, and reducing the difficulty and cost of valve installation.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
