Description

Technical Field

[0001] This utility model relates to the field of shut-off valve technology, specifically a quick-disassembly shut-off valve. Background Technology

[0002] A gate valve, also known as a stop valve, is a forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to ensure a leak-proof seal. The gate valve's opening and closing element is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves linearly along the centerline of the valve seat. Existing gate valves typically use flange connections to external pipelines, followed by the addition of external sealing components to ensure a tight seal. Both assembly and disassembly require significant time and effort, and since valves are usually installed in batches, the time required for installation and disassembly increases exponentially. Therefore, this application proposes a quick-disassembly gate valve. Utility Model Content

[0020] 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a quick-disassembly shut-off valve, including a valve body 1, with fixed pipes 2 inserted and installed on both the left and right sides of the valve body 1, and an external pipe 3 movably installed on the outside of the fixed pipes 2. The inner diameter of the fixed pipes 2 and the outer diameter of the external pipes 3 are the same. A positioning component is provided on the outside of the external pipes 3 and the outside of the fixed pipes 2. The positioning component includes a fixed sleeve 5, which is sleeved and fixedly installed on the outer wall of the external pipes 3. Several slots 9 are provided on the outer wall of the fixed sleeve 5. A locking block 11 is inserted and installed in the inner cavity of each of the slots 9. A movable plate 10 is fixedly installed on the outside of each of the locking blocks 11. The outside of each of the movable plates 10 is movably connected to the outer wall of the fixed pipes 2.

[0022] The initial connection is made by inserting the external pipe 3 into the fixed pipe 2. The connection is then reinforced by the snap-fit ​​between the clip 11 and the slot 9 to ensure a firm connection between the fixed pipe 2 and the external pipe 3 and to facilitate subsequent disassembly.

[0023] Please see Figure 3 , Figure 4 and Figure 5 The positioning component also includes a fixing ring 7, which is fixedly connected to the outer wall of the fixing pipe 2. Several empty shells 8 are fixedly connected to the outer wall of the fixing ring 7. Several movable plates 10 extend to the inner cavity of the corresponding empty shell 8 from the side away from the corresponding card block 11, and are fixedly connected to one side of the inner wall of the empty shell 8 by a spring 12.

[0024] The movable plate 10 and the empty shell 8 are connected by a spring 12, which ensures that the locking block 11 can be pulled out of the slot 9 during subsequent disassembly, making it convenient for subsequent disassembly work.

[0025] Please see Figure 4 and Figure 5 Each of the movable plates 10 has a positioning hole 14, and each of the hollow shells 8 has a positioning bolt 13 installed through it on its outer wall. One end of the positioning bolt 13 is threaded into the inner cavity of the corresponding positioning hole 14.

[0026] The movable plate 10 is fixed to the empty shell 8 by inserting the positioning bolt 13 into the positioning hole 14, which further enables the positioning of components such as the locking block 11, thereby ensuring the secure installation between the fixed pipe 2 and the external pipe 3.

[0027] Please see Figure 4 and Figure 5 The number of empty shells 8 and movable plates 10 are both set to six, and the six empty shells 8 are evenly distributed in a ring.

[0028] Among them, the multiple hollow shells 8 and movable plates 10 evenly distributed in a ring ensure that the force distribution of the multiple clamping blocks 11 and clamping slots 9 is uniform, thereby ensuring the stability of the installation between the fixed pipe 2 and the external pipe 3.

[0029] Please see Figure 3 A second sealing ring 6 is fixedly installed on the outer wall of the fixed pipe 2, and the outer wall of the second sealing ring 6 is tightly attached to the inner wall of the fixed sleeve 5.

[0030] Among them, the No. 2 sealing ring 6 is used to improve the sealing effect between the fixed pipe 2 and the fixed sleeve 5, and further ensure the connection effect between the fixed pipe 2 and the external pipe 3.

[0031] Please see Figure 3 A No. 4 sealing ring is fixedly installed on the outer wall of the external pipe 3, and the outer wall of the No. 4 sealing ring is tightly attached to the inner wall of the fixed pipe 2.

[0032] The use of sealing ring 4 improves the sealing effect between the fixed pipe 2 and the external pipe 3, thereby preventing subsequent leakage.

[0033] Working principle: When using this application, firstly, pull multiple locking blocks 11 outwards, causing each locking block 11 to pull the corresponding movable plate 10 to move. The movable plate 10 stretches the corresponding spring 12. Then, insert the external pipe 3 into the corresponding fixed pipe 2, ensuring a tight seal between the external pipe 3 and the fixed pipe 2. Next, using the first sealing ring 4 and the second sealing ring 6, the sealing effect between the fixed pipe 2 and the external pipe 3 is ensured, preventing leakage. At this time, release the multiple locking blocks 11, allowing each locking block 11 to reset under the elastic force of the corresponding spring 12 and snap into the corresponding slot 9, achieving pre-fixation between the fixed pipe 2 and the external pipe 3. Then, pass multiple positioning bolts 13 through the hollow shell 8 and threadedly connect them to the positioning holes 14 on the movable plate 10, achieving positioning between the movable plate 10 and the hollow shell 8, further ensuring the fixation between the fixed pipe 2 and the external pipe 3. For subsequent disassembly, simply remove the positioning bolts 13 to achieve quick disassembly between the fixed pipe 2 and the external pipe 3.
