In a preferred embodiment of the present application, for installing a seal in a valve port 11 of a valve duct shown in fig. 1 and 2, as shown in fig. 3 to 7, an installation tool for a seal ring comprises a connecting base 2 and a guiding connecting rod 3; a through compression hole 21 is formed in the connecting seat 2, and the diameter of the compression hole 21 is gradually reduced from top to bottom; the minimum diameter of the compression hole 21 is smaller than or equal to the diameter of the valve port 11; the diameter of the top of the compression hole 21 is larger than the diameter of the outer ring of the sealing ring; the bottom of the guide connecting rod 3 is provided with a pushing part 31, and the pushing part 31 is used for pushing the sealing ring to move in the compression hole 21; the shape of the pushing part 31 is the same as that of the compression hole 21; when the pushing portion 31 is completely sleeved in the compression hole 21, the outer wall of the pushing portion 31 is attached to the inner wall of the compression hole 21; the diameter of the pushing part 31 is larger than the diameter of the inner ring of the sealing ring.
Specifically, as shown in fig. 3 to 6, the diameter of the top of the compression hole 21 is larger than the diameter of the outer ring of the seal ring, so that the seal ring can be placed in the compression hole 21 without being compressed, the installation is convenient, and the installation efficiency is improved. The minimum diameter of the compression hole 21 is smaller than or equal to the diameter of the valve port 11, so as to ensure that the compressed size of the sealing ring can enter the valve port 11 and be sleeved in the lip-shaped groove 111. The diameter of the pushing portion 31 is larger than the diameter of the inner ring of the sealing ring, so as to ensure that the pressure of the pushing portion 31 on the sealing ring is always downward, rather than all around, when the pushing portion 31 pushes the sealing ring in the compression hole 21. Therefore, the sealing ring can be compressed downwards under the action of the pushing part 31 and is not sleeved on the outer wall of the pushing part 31, so that the sealing ring is clamped in the compression hole 21. In this embodiment, before the sealing ring is mounted in the lip groove 111, the bottom surface of the connecting seat 2 is attached to the top surface of the valve nozzle 1, so that the compression hole 21 is aligned with the valve port 11. After alignment, the connection between the connecting socket 2 and the valve nozzle 1 is fixed, and then the sealing ring is placed in the compression hole 21. Since the diameter of the top of the compression hole 21 is made larger than the outer diameter of the seal ring at the time of manufacturing, the seal ring can be placed in the compression hole 21 without compression. After the sealing ring is installed in the compression hole 21, the guide connecting rod 3 is used again to make the bottom surface of the pushing portion 31 adhere to the top surface of the sealing ring, and because the diameter of the pushing portion 31 is larger than that of the inner ring of the sealing ring, when the guide connecting rod 3 moves downwards, the bottom surface of the pushing portion 31 can press the sealing ring to move downwards. Since the diameter of the compression hole 21 is reduced from the top to the bottom, the diameter of the packing is also reduced during the downward movement when the packing is pressed against the inside of the compression hole 21. In this embodiment, the minimum diameter of the compression hole 21 is smaller than or equal to the diameter of the valve port 11, so that when the sealing ring passes through the compression hole 21 under the pushing of the pushing portion 31, the outer diameter of the sealing ring is also smaller than or equal to the diameter of the valve port 11, so as to enter the valve port 11. After entering the valve port 11, the sealing ring is pushed by the pushing portion 31 to move to the position of the lip-shaped groove 111. When the sealing ring moves to the lip-shaped groove 111, no inner wall extrudes the sealing ring, and the sealing ring is recovered through the elastic action and sleeved in the lip-shaped groove 111. The utility model provides a sealing washer mounting tool, rely on compression hole 21 with under the squeezing action of promotion portion 31 for the sealing washer reduces gradually in compression hole 21 to being less than or equal to the diameter of valve port 11, then the cover is located in lip recess 111, compare in traditional mounting method, this instrument makes the installation of sealing washer convenient and fast more, has reduced installation time, has improved the installation effectiveness.
Further, the bottom surface of the pushing portion 31 is provided with a guide portion 32 extending outward, and the diameter of the guide portion 32 is smaller than the diameter of the inner ring of the seal ring. When the sealing ring moves in the compression hole 21, the sealing ring is pressed downward by the pushing portion 31 and pressed inward by the inner wall of the compression hole 21. However, the seal ring is made of a rubber material and has flexibility, so that when the seal ring is pressed downward by the pushing portion 31 and inward by the inner wall of the compression hole 21, the deformed shape of the seal ring may be irregular, and thus when the irregularly deformed seal ring is fitted in the lip groove 111, the seal may be incomplete, resulting in poor sealing performance, and fluid may leak from the valve core. Therefore, a guide portion 32 extending outward is provided on the bottom surface of the pushing portion 31. After the sealing ring is installed in the compression hole 21, the guide connecting rod 3 firstly penetrates the guide portion 32 through the inner ring of the sealing ring, and then the bottom surface of the pushing portion 31 is attached to the top surface of the sealing ring. This is to ensure that the pressure direction of the inner wall of the compression hole 21 is directed to the center line of the compression hole 21 when the compression hole 21 moves, so that the sealing ring is uniformly stressed and has a regular shape of compression deformation, and the sealing ring can be aligned after being sleeved in the lip-shaped groove 111.
Specifically, as shown in fig. 6, the compression hole 21 includes a tapered compression portion 211 and a square buffer portion 212;
the compression part is positioned at the top of the compression hole 21, the square buffer part 212 is positioned at the bottom of the compression hole 21, and the bottom of the compression part is communicated with the top of the square buffer part 212. The tapered compression portion 211 is used for compressing the outer diameter of the sealing ring, so as to ensure that the sealing ring can be sleeved in the lip-shaped groove 111. The square buffer portion 212 is mainly used to ensure that the sealing ring is deformed regularly during compression, so as to ensure that the sealing ring can be completely sleeved on the lip-shaped groove 111 of the bathroom heater, and the valve port 11 has good sealing performance. It is worth noting that in actual production manufacturing, the shape of the pushing portion is the same as that of the compression hole. Accordingly, the pushing portion is also provided with a tapered pushing portion and a square pushing portion, respectively.
Further, the diameter of the tapered compression part 211 decreases from top to bottom; the minimum diameter of the tapered compression part 211 is equal to the diameter of the square buffer part 212; the diameter of the square buffer part 212 is smaller than or equal to the diameter of the valve port 11. This is to ensure that the sealing ring can pass through the compression hole 21 and be sleeved in the lip-shaped groove 111, thereby ensuring the sealing performance of the valve port 11.
In the present embodiment, the top of the valve nozzle 1 is cylindrical. Preferably, the bottom of the connecting base 2 is provided with a connecting groove 22, and the connecting base 2 is installed on the valve nozzle 1 by sleeving the connecting groove 22 on the top of the valve nozzle 1; the bottom of the compression hole 21 communicates with the coupling groove 22. This is to allow the connecting socket 2 to be clamped to the top of the valve nozzle 1 through the connecting groove 22, so as to reduce the side-to-side swinging of the connecting socket 2, fix the connection of the connecting socket 2 and the valve nozzle 1, and thus fix the alignment of the compression hole 21 and the valve port 11, and ensure that the sealing ring can enter the lip-shaped groove 111 from the compression hole 21. In other embodiments, the bottom of the connecting base 2 may be cylindrical, but instead, the top of the valve nozzle 1 is provided with a connecting cavity, in which the valve port 11 is provided. Before the sealing ring is installed, the connecting seat 2 is sleeved in the connecting cavity, so that the connection between the connecting seat 2 and the valve nozzle 1 can be stabilized.
In actual production, the connecting socket 2 and the guiding connecting rod 3 are made of various materials. In this embodiment, the connecting seat 2 and the guiding connecting rod 3 are preferably made of hard plastic. Because the connecting seat 2 and the guide connecting rod 3 made of hard plastics are convenient to process and low in cost.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the utility model and should not be construed in any way as limiting the scope of the utility model. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
