Description

Technical Field

[0001] This utility model relates to the field of high-purity pressure reducing valve technology, and in particular to a quick-install high-purity pressure reducing valve. Background Technology

[0002] High-purity pressure reducing valves are key components in fluid control systems, primarily used to reduce and stabilize system pressure. Traditionally, high-purity pressure reducing valves are connected to pipelines using bolts or threaded connections, though some use quick-connect couplings. However, in actual disassembly and assembly work, we have found that bolted connections are time-consuming, requiring repeated rotation of the bolts and sequential disassembly and assembly, resulting in low efficiency. Quick-connect couplings, on the other hand, are relatively labor-intensive in practical use. To ensure the secure connection, the spring force of the quick-connect coupling is designed to be relatively large, requiring the user to exert force greater than the spring force when operating it. This is easier for strong individuals but more difficult for those with less strength, directly impacting the efficiency of valve body and pipeline installation.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a quick-installation high-purity pressure reducing valve, which solves the aforementioned problems existing in the use of the prior art.

Three docking seats are integrally formed on the surface of the pressure reducing valve body. Two docking seats have docking pipes inserted into their outer sides. Insertion holes are opened on the outer sides of the docking seats. The docking pipes are inserted into the corresponding insertion holes. Locking grooves are opened on both sides of the inner cavity of the insertion hole. A groove is opened at the top of the inner cavity of the locking groove. A movable cavity is opened on one side of the inner cavity of the locking groove. The insertion hole, locking groove, and groove are interconnected. A fixing rod is fixedly connected to one side of the inner cavity of the movable cavity. A locking block is slidably installed on the surface of the fixing rod. A spring is sleeved on the surface of the fixing rod. The two ends of the spring are fixedly connected to the locking block and the inner wall of the movable cavity, respectively.

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] A quick-install high-purity pressure reducing valve includes a pressure reducing valve body 1. Three docking seats 2 are integrally formed on the surface of the pressure reducing valve body 1. Two docking seats 2 have docking pipes 4 inserted into their outer sides. Insertion holes 5 are provided on the outer sides of the docking seats 2, and the docking pipes 4 are inserted into the corresponding insertion holes 5. Locking grooves 6 are provided on both sides of the inner cavity of each insertion hole 5. A groove 16 is provided at the top of the inner cavity of each locking groove 6. A movable cavity 7 is provided on one side of the inner cavity of each locking groove 6. The insertion holes 5, locking grooves 6, and grooves 16 are interconnected. A fixing rod 8 is fixedly connected to one side of the inner cavity of the movable cavity 7. A locking block 9 is slidably mounted on the surface of the fixing rod 8. A spring 10 is sleeved on the surface of the fixing rod 8. The two ends of the spring 10 are fixedly connected to the inner walls of the locking block 9 and the movable cavity 7, respectively. Clamping blocks 12, which are compatible with the locking grooves 6, locking blocks 9, and grooves 16, are fixedly connected to both sides of the docking pipes 4. An inclined surface 17 is provided at the bottom of the locking block 9.

[0023] The specific usage process is as follows: During installation, align the connecting pipe 4 with the corresponding mounting hole on the connecting seat 2, and simultaneously align the locking block 12 on the connecting pipe 4 with the groove 16 on the connecting seat 2. Then, insert the connecting pipe 4, and at the same time, the locking block 12 is also inserted into the groove 16. During this process, as the user presses the locking block 12, it will force the locking block 9 to slide into the movable cavity 7. At the same time, the locking block 9 also slides on the fixed rod 8, and the locking block 9 will also compress the spring 10 until the locking block 12 is inserted into the locking groove 6. After that, the locking block 12 will disengage from the locking block 9. Then, rotate the connecting pipe 4 clockwise, and the locking block 12 will follow the rotating rod of the connecting pipe 4 to one side of the inner cavity of the locking groove 6. At this time, the locking block 12 and the groove 16 are misaligned. As the locking block 12 moves, at this time... Under the action of spring 10, locking block 9 will spring back to its original position, and then one side of locking block 9 will abut against one side of locking block 12, thereby positioning locking block 12 in locking groove 6. Without human intervention, locking block 12 cannot be moved out of locking groove 6, thus completing the docking installation of docking pipe 4. The end of docking pipe 4 will be inserted into pressure reducing valve body 1, and the sealing ring 13 on docking pipe 4 will be tightly attached to the inner wall of pressure reducing valve body 1, sealing the gap between the outer wall of docking pipe 4 and the inner wall of pressure reducing valve body 1, preventing leakage of pressure reducing valve, and ensuring the sealing of valve body. It should be noted that the connection method of pressure gauge 3 and docking pipe 4 is the same. When disassembling and assembling, simply follow the disassembly and assembly steps of docking pipe 4. When disassembling docking pipe 4... First, move the actuating block 11 away from the docking pipe 4. The actuating block 11 will move the corresponding locking block 9 to the corresponding side, while the locking block 9 slides on the fixed rod 8, compressing the spring 10. Then, rotate the docking pipe 4 counterclockwise. The docking pipe 4 will move the locking block 12 within the locking groove 6, aligning the locking block 12 with the groove 16. At this point, the locking block 9 enters the corresponding movable cavity 7. Then, pull the docking pipe 4 upwards, and the locking block 12 will also move upwards from the groove 16 along with the docking pipe 4, thus completing the disassembly of the docking pipe 4. Finally, release the actuating block 11. Under the action of the spring 10, the locking block 9 will return to its original position for future use, providing convenience for the user's work. This method changes the docking axis between the pipe and the valve body. The angled assembly method ensures a firm and stable connection between the pipeline and the valve body, while also reducing the effort required for disassembly and assembly. The spring strength does not need to be designed to be too high, allowing for easy operation by people of all strengths. This increases the user's disassembly and assembly speed, reduces workload, and provides convenience for users. Therefore, a structure design enabling quick disassembly and assembly is adopted. The entire quick-disassembly assembly allows for rapid installation and removal of the pipeline and valve body, improving disassembly and assembly speed, increasing maintenance efficiency, and reducing maintenance costs. The structure is simple and has low manufacturing cost. Pressure gauge 3 is used to monitor and display pressure values. When pressure gauge 3 detects a pressure change, its pointer will point to the corresponding value for easy user viewing.To facilitate timely and appropriate handling by users and provide convenience for their work, two toggle blocks 11 are used to control the movement of locking blocks 9. When disassembling the connecting pipe 4, the user can move the toggle blocks 11 to move the locking blocks 9, releasing the restriction on the locking blocks 12, thereby quickly completing the disassembly of the connecting pipe 4. Furthermore, the symmetrical arrangement of the two toggle blocks 11 enhances the aesthetics of the pressure reducing valve. The valve body mounting bracket 14 is fixed to the pressure reducing valve body 1 and is used to install the entire pressure reducing valve on equipment or in a suitable position on the pipeline, ensuring the stability of the pressure reducing valve's operation and providing convenience for users. The adjusting knob 15 is used to control the operation of the pressure reducing valve body 1. By rotating the adjusting knob 15, the operating mode of the pressure reducing valve body 1 can be controlled and adjusted to meet more work needs, providing convenience for users.

Furthermore, the symmetrical arrangement of the two toggle blocks 11 can also improve the aesthetics of the pressure reducing valve.

[0028] A sealing ring 13 is embedded in the bottom of the surface of the docking pipe 4. The bottom end of the docking pipe 4 is inserted into the pressure reducing valve body 1, and the sealing ring 13 is tightly attached to the inner wall of the pressure reducing valve body 1.

[0029] Specifically, the sealing ring 13 is designed so that when the end of the connecting pipe 4 is inserted into the pressure reducing valve body 1, the sealing ring 13 on the connecting pipe 4 is tightly attached to the inner wall of the pressure reducing valve body 1, sealing the gap between the outer wall of the connecting pipe 4 and the inner wall of the pressure reducing valve body 1, preventing leakage of the pressure reducing valve and ensuring the sealing performance of the valve body.
