Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a quick-disassembly gate valve with a multi-stage sealing structure. Background Technology

[0002] Gate valves, also known as shut-off valves, are a type of forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force of the valve stem and packing and the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open the valve, so the diameter of the valve stem must be larger; otherwise, the valve stem may bend.

[0003] According to a utility model patent with Chinese patent application number 202123098212.2, an air conditioner shut-off valve that is easy to disassemble and install can solve the problem of insufficient sealing when connecting the connecting pipe and the installation pipe. However, since the shut-off valve is installed between the pipes, it is very inconvenient to disassemble and maintain the shut-off valve. It is not possible to adjust the installation and disassembly of the shut-off valve according to the distance between the pipes. Therefore, it is necessary to propose a quick-disassembly shut-off valve with a multi-stage sealing structure to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-assembly and disassembly gate valve with a multi-stage sealing structure. It has advantages such as the ability to adaptively adjust the distance between the two ends of the gate valve according to the spacing between the pipes, thus solving the problem in the prior art where it is inconvenient to adaptively adjust the distance between the inlet and outlet ports of the gate valve and the connecting pipes.

[0005] To achieve the above-mentioned purpose of adaptively adjusting the distance between the two ends of the shut-off valve according to the spacing between the pipes, this utility model provides the following technical solution: a quick-release shut-off valve with a multi-stage sealing structure, including a shut-off valve body, with fixing rings provided on both the left and right sides of the shut-off valve body, a drain pipe inserted into the inside of the shut-off valve body, a stabilizing ring provided on the outside of the drain pipe, a positioning component movably installed inside the stabilizing ring, and an installation component movably installed on the outside of the fixing ring.

[0006] The positioning component includes a rotating ring, which is movably mounted on the outside of the stabilizing ring. A through-post is provided on the inner wall of the rotating ring, and a rotating sleeve is located at one end of the through-post. A threaded cylinder is threadedly connected to the inside of the rotating sleeve.

[0007] Furthermore, the mounting assembly includes a rotary knob, which is movably mounted on the outside of the fixing ring. A threaded rod is provided on one side of the rotary knob, and a positioning cylinder is sleeved on the outside of the threaded rod.

[0008] Furthermore, a limiting groove is formed inside the fixing ring, and the positioning cylinder is slidably installed inside the limiting groove.

[0009] Furthermore, a positioning hole is provided on the outside of the drain pipe, and the positioning cylinder is positioned and installed inside the positioning hole.

[0010] Furthermore, a third sealing ring is provided on one side of the rotating sleeve, and a second sealing ring is provided on one side of the threaded cylinder.

[0011] Furthermore, the rotating sleeve is movably installed inside the stabilizing ring, and a first sealing ring is provided on the outside of the drain pipe.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This multi-stage sealing structure quick-release gate valve, through the installation assembly, allows the drain pipe to be inserted into the right side of the gate valve body. Rotating the rotary knob will cause the threaded rod to rotate. Due to the limiting effect of the limiting groove on the positioning cylinder, the threaded rod can drive the positioning cylinder to move to one side inside the limiting groove, thereby pushing it into the positioning hole through the limiting groove. This completes the installation of the drain pipe on the side of the gate valve body, making it convenient for the gate valve body to be installed and removed via the positioning assembly.

[0014] This multi-stage sealing structure quick-release gate valve, by setting a positioning component, aligns the threaded cylinder with the installation pipe and rotates the rotating ring. The rotating ring drives the rotating sleeve to rotate through the through column, and the aligned installation pipe can limit the threaded cylinder, allowing the threaded cylinder to extend into the interior of the installation pipe. The drain pipes at both ends of the gate valve body are extended to adapt to installation pipes with different intervals, which can facilitate quick and easy disassembly and assembly of the gate valve body.

[0029] 4) Finally, the threaded cylinder 704 is inserted into the installation pipe through the positioning component 7 to install the shut-off valve body 1.

[0030] In summary, this multi-stage sealing structure quick-release stop valve, by setting the installation component 8, inserts the drain pipe 3 into the right side of the stop valve body 1, and rotates the rotary knob 801. Rotating the knob 801 will drive the threaded rod 801 to rotate. Due to the limiting effect of the limiting groove 9 on the positioning cylinder 803, the threaded rod 801 can drive the positioning cylinder 803 to move to one side inside the limiting groove 9, thereby pushing it into the positioning hole 5 through the limiting groove 9, thus completing the installation of the drain pipe 3 on the side of the stop valve body 1, thereby facilitating the installation and disassembly of the stop valve body 1 through the positioning component 7.

[0031] Furthermore, by setting the positioning component 7, the threaded cylinder 704 is aligned with the installation pipe, and the rotating ring 701 is rotated. The rotating ring 701 will drive the rotating sleeve 703 to rotate through the through column 702. The aligned installation pipe can limit the threaded cylinder 704, allowing the threaded cylinder 704 to extend into the interior of the installation pipe. The drain pipes 3 at both ends of the shut-off valve body 1 are extended so as to adapt to installation pipes with different intervals, which can facilitate the quick and easy disassembly and assembly of the shut-off valve body 1.
