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.

[0022] Example 1: Please refer to again Figures 1-5 This utility model provides a sealing compensation device for a sealing valve, including a valve body 100. A connecting pipe 110 is integrally formed on the upper side of the outer side wall of the valve body 100. A connecting groove 120 is opened at the top end of the connecting pipe 110. A sealing mechanism is provided above the valve body 100. The sealing mechanism includes a sealing ring 121, which is fixedly connected to the bottom of the inner cavity of the connecting groove 120. A sealing pipe 130 is inserted into the top end of the connecting pipe 110. The bottom of the sealing pipe 130 extends into the inner cavity of the connecting groove 120. A positioning groove 131 is opened at the bottom of the sealing pipe 130. A sealing ring 132 is fixedly connected to the top of the inner cavity of the groove 131. The bottom of the sealing ring 132 extends into the interior of the sealing ring 121. An extension protrusion ring 140 is integrally formed on the lower side of the inner wall of the sealing tube 130. A sealing plate 150 is fixedly connected to the upper side of the inner wall of the connecting tube 110. The top of the sealing plate 150 extends into the interior of the extension protrusion ring 140. A stud 151 is fixedly connected around the top of the sealing plate 150. The studs 151 are evenly distributed. The top of the stud 151 passes through the extension protrusion ring 140 and extends to the top of the extension protrusion ring 140.

[0023] Specifically, after the sealing tube 130 is installed into the connecting tube 110, the bottom end of the sealing tube 130 is inserted into the connecting groove 120 of the connecting tube 110 to form a first sealing partition. At the same time, the sealing ring 132 in the bottom positioning groove 131 of the sealing tube 130 is also inserted into the sealing ring 121 in the connecting groove 120, forming a second sealing partition. The sealing plate 150 installed in the connecting tube 110 is also inserted into the extension protrusion 140 in the sealing tube 130 to seal the gap at the connection between the inner side of the connecting tube 110 and the sealing tube 130, forming a third sealing partition to seal the gap at the connection between the connecting tube 110 and the sealing tube 130.

[0024] Example 2: Please refer to again Figures 1-5 An installation chamber 200 is provided above the valve body 100. The installation chamber 200 is fixedly connected to the outer wall of the connecting pipe 110. The installation chamber 200 has installation grooves 210 on the left and right sides inside. The installation chamber 200 is provided with a positioning mechanism, which includes left and right mounting plates 220. The left and right mounting plates 220 are slidably connected to the inner cavity of the left and right mounting grooves 210. The inner wall of the left and right mounting plates 220 is fixedly connected with positioning tenons 221. The ends of the left and right positioning tenons 221 pass through the installation chamber 200, the sealing pipe 130 and the sealing ring 121 and extend into the interior of the connecting pipe 110. Threaded connecting rods 230 are screwed to the left and right sides of the outer wall of the installation chamber 200. The ends of the left and right threaded connecting rods 230 pass through the installation chamber 200 and extend into the inner cavity of the left and right mounting grooves 210. The ends of the left and right threaded connecting rods 230 are rotatably connected to the left and right mounting plates 220. A compression spring 231 is sleeved on the outer wall of the threaded connecting rod 230.

[0025] Specifically, when installing the sealing tube 130, the threaded connecting rods 230 on both sides are rotated to disconnect them from the mounting chamber 200. Then, the threaded connecting rods 230 are pulled outward, causing the mounting plates 220 on both sides to compress the compression spring 231 and move, so that the positioning latch 221 on the mounting plate 220 moves into the mounting groove 210. Then, the sealing tube 130 is inserted into the connecting tube 110. Then, the threaded connecting rods 230 are released, so that the compression spring 231 compressed by the mounting plate 220 is reset and pushes the mounting plate 220 to move, so that the positioning latch 221 is inserted into the sealing ring to fix the sealing ring. Finally, the threaded connecting rods 230 are rotated to connect with the mounting chamber 200, completing the installation.

[0026] Working principle: When installing the sealing tube 130, the threaded connecting rods 230 on both sides are rotated to disconnect them from the installation chamber 200. Then, the threaded connecting rods 230 are pulled outwards, causing the mounting plates 220 on both sides to compress the compression spring 231 and move, moving the positioning latch 221 on the mounting plate 220 into the installation groove 210. The sealing tube 130 is then inserted into the connecting tube 110. The threaded connecting rods 230 are then released, causing the compression spring 231, compressed by the mounting plate 220, to reset and push the mounting plate 220 to move, allowing the positioning latch 221 to insert into the sealing ring and fix it. Finally, the threaded connecting rods 230 are rotated to reconnect the threaded connection. The rod 230 is screwed into the installation chamber 200 to complete the installation. After the sealing tube 130 is installed into the connecting tube 110, the bottom end of the sealing tube 130 is inserted into the connecting groove 120 of the connecting tube 110 to form the first sealing partition. At the same time, the sealing ring 132 in the bottom positioning groove 131 of the sealing tube 130 is also inserted into the sealing ring 121 in the connecting groove 120. The sealing ring 121 and the sealing ring 132 form the second sealing partition. The sealing plate 150 installed in the connecting tube 110 is also inserted into the extension protrusion ring 140 in the sealing tube 130 to seal the gap at the connection between the inner side of the connecting tube 110 and the sealing tube 130, forming the third sealing partition to seal the gap at the connection between the connecting tube 110 and the sealing tube 130.
