Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a quick-install and quick-release gate valve. Background Technology

[0002] Gate valves are commonly used fluid control valves and are widely used in many fields such as petroleum, chemical, water conservancy, and municipal engineering. Traditionally, gate valves are connected to pipelines using flange connections or threaded connections.

[0003] Flange connections require multiple bolts and nuts for fixing. During installation and disassembly, each bolt and nut needs to be tightened or loosened individually, which is a cumbersome process that consumes a lot of time and manpower. This is especially true in some confined installation environments where the operation is even more difficult. Although threaded connections are simpler to operate than flange connections, after long-term use, the threads are prone to corrosion and adhesion, making disassembly very difficult. Often, specialized tools are required, and it may even damage the gate valve or pipeline.

[0004] Therefore, this utility model provides a quick-install and quick-release shut-off valve to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-installation and quick-disassembly shut-off valve, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation and quick-disassembly shut-off valve, comprising a valve body and a pipeline, a positioning component is provided between the valve body and the pipeline, and a fixing component is provided on the outer side of the positioning component. The positioning component includes an outer cylinder and a connecting ring. The outer cylinder is fixedly installed on the left and right sides of the valve body, and the connecting ring is fixedly installed on the inner end of the pipeline. An inner cylinder is fixedly installed on the inner end of the connecting ring, and the inner cylinder is connected to the pipeline through the connecting ring. The inner cylinder is inserted into the corresponding outer cylinder. By inserting the inner cylinder into the outer cylinder, the initial connection and positioning between the valve body and the pipeline can be achieved, preparing for subsequent fixing.

[0007] A sealing ring is fixedly installed on the inner end of the inner cylinder. The sealing ring is fitted to the connection between the outer cylinder and the valve body. The inner cylinder is in communication with the inside of the valve body, and the inner wall of the outer cylinder is fitted to the outer wall of the inner cylinder. The sealing ring enhances the sealing performance at the connection between the inner and outer cylinders and the valve body, preventing fluid leakage. The fit between the inner wall of the outer cylinder and the outer wall of the inner cylinder further improves the stability and sealing performance of the connection.

[0008] A positioning rod is fixedly installed on the left side of the connecting ring, and a positioning groove is opened on the outer side of the outer cylinder. The positioning rod is inserted into the corresponding positioning groove. The cooperation between the positioning rod and the positioning groove can play a role in precise positioning when the connecting ring and the outer cylinder are connected, avoiding misalignment during connection and ensuring that the inner cylinder can be accurately inserted into the outer cylinder.

[0009] The fixing assembly includes a housing, which is fixedly installed on the outside of the outer cylinder. A housing is fixedly installed on the outside of each positioning slot. A plug is slidably inserted into the bottom wall of the housing. A slot is provided on the top of the positioning rod, and the plug is inserted into the corresponding slot. The cooperation between the plug and the slot fixes the positioning rod inside the positioning slot, thereby fixing the connecting ring to the outer cylinder and thus stably connecting the pipe to the valve body.

[0010] A screw is rotatably connected between the front and rear inner walls of the outer casing. The threads on both sides of the screw center have different directions of rotation, and sliders are screwed to the outer sides of the threads with different directions of rotation. A connecting rod is hinged between the bottom of each slider and the top of the insert. When the screw is rotated, due to the different directions of rotation of the threads on both sides of the screw center, the two sliders will move towards or away from each other along the screw. This, in turn, drives the insert to move up and down via the connecting rod, thus enabling the insert to be inserted into or separated from the slot. The operation is convenient.

[0011] The top of the slider slides against the inner top of the housing. The screw's thread lead angle is less than or equal to the equivalent friction angle. The outer side of the screw is coated with lubricating and protective grease. The sliding contact between the top of the slider and the inner top of the housing guides the slider's movement, ensuring stable motion. The screw's thread lead angle provides a self-locking function; the slider will not move without being actively rotated, thus ensuring the connection stability between the insert and the slot. The grease coating reduces friction between the screw and the slider, while also protecting the screw and extending its service life.

[0012] A rotating rod is rotatably connected to the outer side of the housing. A knob is fixedly installed at the outer end of the rotating rod, and the inner end of the rotating rod movably passes through the side wall of the housing and is fixedly connected to a screw. By rotating the knob, the rotating rod and screw can be rotated, which is convenient for operators to operate without the need for other tools, further improving the ease of installation and disassembly.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 4 This application provides a quick-installation and quick-disassembly shut-off valve, including a valve body 1 and a pipeline 4. A positioning component 2 is provided between the valve body 1 and the pipeline 4, and a fixing component 3 is provided on the outside of the positioning component 2.

[0026] The positioning assembly 2 includes an outer cylinder 21 and a connecting ring 22. The outer cylinder 21 is fixedly installed on the left and right sides of the valve body 1, and the connecting ring 22 is fixedly installed on the inner end of the pipe 4. An inner cylinder 23 is fixedly installed on the inner end of the connecting ring 22. The inner cylinder 23 is connected to the pipe 4 through the connecting ring 22 and is inserted into the corresponding outer cylinder 21. During installation, the connecting ring 22 at the inner end of the pipe 4 is first used to align the inner cylinder 23 with the outer cylinders 21 on both sides of the valve body 1, and then the inner cylinder 23 is inserted into the outer cylinder 21 to complete the initial connection and positioning.

[0027] A sealing ring 24 is fixedly installed on the inner end of the inner cylinder 23. The sealing ring 24 fits against the connection between the outer cylinder 21 and the valve body 1. The inner cylinder 23 is in communication with the inside of the valve body 1, and the inner wall of the outer cylinder 21 fits against the outer wall of the inner cylinder 23. After the inner cylinder 23 is inserted into the outer cylinder 21, the sealing ring 24 will fit tightly against the connection between the outer cylinder 21 and the valve body 1, effectively preventing fluid leakage from the connection. At the same time, the fit between the inner wall of the outer cylinder 21 and the outer wall of the inner cylinder 23 also enhances the stability of the connection.

[0028] A positioning rod 25 is fixedly installed on the left side of the connecting ring 22, and a positioning groove 26 is opened on the outer side of the outer cylinder 21. The positioning rod 25 is inserted into the corresponding positioning groove 26. When the inner cylinder 23 is inserted, the positioning rod 25 on the connecting ring 22 will align with the positioning groove 26 on the outer cylinder 21 and be inserted into it, further ensuring the accuracy of the connection between the inner cylinder 23 and the outer cylinder 21 and avoiding misalignment.

[0029] The fixing component 3 includes a housing 31, which is fixedly installed on the outside of the outer cylinder 21. A housing 31 is also fixedly installed on the outside of each positioning groove 26. A plug 32 is slidably inserted into the bottom wall of the housing 31. A slot 33 is provided on the top of the positioning rod 25, and the plug 32 is inserted into the corresponding slot 33. When the positioning rod 25 is inserted into the positioning groove 26, the plug 32 on the bottom wall of the housing 31 will insert into the slot 33 on the top of the positioning rod 25, fixing the positioning rod 25 in the positioning groove 26, thereby fixing the connecting ring 22 to the outer cylinder 21.

[0030] A screw 34 is rotatably connected between the front and rear inner walls of the outer casing 31. The threads on both sides of the center of the screw 34 have different directions of rotation. Slider 35 is screwed to the outer side of each thread with a different direction of rotation. A connecting rod 36 is hinged between the bottom of each slider 35 and the top of the insert 32. When fixing is required, rotating the screw 34 causes the two sliders 35 to move towards each other along the screw 34 due to the different directions of rotation of the threads on both sides of the center of the screw 34. This pushes the insert 32 downward through the connecting rod 36, allowing it to be inserted into the slot 33. When disassembly is required, rotating the screw 34 in the opposite direction causes the two sliders 35 to move away from each other. This pulls the insert 32 upward through the connecting rod 36, allowing it to be pulled out of the slot 33.

[0031] The top of slider 35 slides against the inner top of housing 31. The thread lead angle of screw 34 is less than or equal to the equivalent friction angle. The outer side of screw 34 is coated with lubricating and protective grease. During movement, the top of slider 35 slides against the inner top of housing 31, ensuring the stability of movement. The thread lead angle of screw 34 is designed to have a self-locking function, preventing it from rotating after fixing, thus ensuring the stability of the connection. The presence of grease reduces friction between screw 34 and slider 35 and prevents screw 34 from corroding.

[0032] A rotating rod 37 is rotatably connected to the outer side of the housing 31. A knob 38 is fixedly installed at the outer end of the rotating rod 37, and the inner end of the rotating rod 37 movably passes through the side wall of the housing 31 and is fixedly connected to the screw 34. The operator rotates the knob 38 to drive the rotating rod 37 to rotate, which in turn drives the screw 34 to rotate. The operation is simple and convenient and does not require any additional tools.

[0033] In summary, this quick-installation and quick-disassembly gate valve achieves initial positioning and connection through the positioning component 2 during installation, and then quickly fixes itself through the fixing component 3; during disassembly, the fixing component 3 can be reversed to achieve quick separation, effectively solving the problem of inconvenient installation and disassembly of traditional gate valves.

[0034] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and all electrical components mentioned in this document are powered by external power supply lines.

[0035] Working Principle: During operation, the valve body 1 and the pipeline 4 are first connected via the positioning component 2: the connecting ring 22 on the pipeline 4 drives the inner cylinder 23 to align with the outer cylinders 21 on both sides of the valve body 1, and the inner cylinder 23 is inserted into the outer cylinder 21. At the same time, the positioning rod 25 on the connecting ring 22 is inserted into the positioning groove 26 of the outer cylinder 21, completing the initial positioning. The sealing ring 24 on the inner side of the inner cylinder 23 fits against the connection between the outer cylinder 21 and the valve body 1, achieving a seal. During fixing, the knob 38 of the fixing component 3 is rotated, which drives the screw 34 inside the housing 31 to rotate via the rotating rod 37. Because the threads on both sides of the screw 34 are reversed, the sliders 35 move towards each other, pushing the insert block 32 into the slot 33 of the positioning rod 25 via the connecting rod 36. During disassembly, the knob 38 is rotated in the opposite direction, the sliders 35 move away from each other, and the connecting rod 36 pulls the insert block 32 out of the slot 33. The self-locking characteristic of the screw 34 ensures a stable connection, and the surface lubricant reduces wear and prevents rust.
