By setting up an installation mechanism, the installation and disassembly of the installation pipe 1 and the connecting pipes 3 are convenient, and the operation steps are simple.

[0025] The installation mechanism includes a positioning cylinder 4, a pressing rod 5, a clamping plate 6, and a spring 9. The positioning cylinder 4 is fixedly installed on the outer surface of the installation tube 1. Several grooves 10 are formed on the outer surface of the installation tube 1. The clamping plate 6 is set inside the grooves 10. One end of the bottom of the pressing rod 5 passes through the positioning cylinder 4 and is fixedly connected to one side of the clamping plate 6. Several springs 9 are provided, and both ends are fixedly connected to the clamping plate 6 and the grooves 10 respectively. The inner surface of the connecting tube 3 is provided with a groove 11 that matches the clamping plate 6. Specifically, the positioning cylinder 4 serves to limit the pressing rod 5 and improve the stability of the pressing rod 5's up and down movement. The pressing rod 5 and the clamping plate 6 adopt an integrated structure. When the connecting tube 3 needs to be installed, the pressing rod 5 is manually pressed to move the pressing rod 5 downward. When the pressing rod 5 moves, it drives the clamping plate 6 to move, and the spring 9 is compressed, inserting the installation tube 1 into the connecting tube 3. When the pressing rod 5 is released, the clamping plate 6 extends into the groove 11 under the action of the spring 9, thus fixing the connecting tube 3 and preventing the connecting tube 3 from falling off.

[0026] Waterproof protrusions 12 are fixedly connected to the inner surfaces of both connecting pipes 3. Waterproof grooves 13 matching the waterproof protrusions 12 are opened at both ends of the mounting pipe 1. A silicone gasket 14 is set inside the waterproof groove 13. Specifically, the waterproof protrusions 12 can effectively prevent fluid from overflowing, and the sealing effect is improved by setting the silicone gasket 14.

[0027] Please see Figure 1-2 As shown, furthermore, the end of the connecting pipe 3 away from the mounting pipe 1 is connected to a transmission pipe 7.

[0028] In this embodiment, the transmission pipe 7 facilitates fluid flow.

[0029] Please see Figure 2-3 As shown, furthermore, a rubber column 8 is provided inside the groove 10. The two ends of the rubber column 8 are fixedly connected to the card plate 6 and the groove 10 respectively, and the spring 9 is sleeved on the outer surface of the rubber column 8.

[0030] In this embodiment, the rubber pillar 8 effectively improves the stability of the clamping plate 6 in fixing the connecting pipe 3.

[0031] Please see Figure 2-3 As shown, the end of the card plate 6 away from the pressing rod 5 is further designed with a sloping structure.

[0032] In this embodiment, convenience is improved.

[0033] Please see Figure 2 As shown, the waterproof protrusion 12 has a T-shaped cross-section, and the waterproof groove 13 has a ring-shaped structure.

[0034] In this embodiment, a comprehensive sealing effect is achieved.

[0035] Please see Figure 1-2 As shown, the installation mechanism is further configured in several groups, arranged in a ring at equal intervals.

[0036] In this embodiment, the installation mechanism is provided in six sets to improve the stability of the installation effect.

[0037] The working principle of this utility model:

[0038] The two connecting pipes 3 are installed onto the mounting pipe 1 using the installation mechanism. First, manually press the pressing rod 5 to move it downwards. As the pressing rod 5 moves, it moves the clamping plate 6, compressing the spring 9 and inserting the mounting pipe 1 into the connecting pipe 3. Release the pressing rod 5, and under the action of the spring 9, the clamping plate 6 extends into the clamping groove 11, thus fixing the connecting pipe 3 and preventing it from falling off. At the same time, the waterproof protrusion 12 on the connecting pipe 3 is inserted into the waterproof groove 13 of the mounting pipe 1. The waterproof protrusion 12 can effectively prevent fluid from overflowing, and the silicone gasket 14 can improve the sealing effect.

[0039] This invention solves the problem of complex steps and long installation times required for traditional gate valves. By simplifying the connection and sealing methods, installation time can be significantly shortened, improving equipment commissioning efficiency and reducing downtime, allowing production lines to resume normal operation more quickly.

Especially in situations with short equipment maintenance and replacement cycles, it effectively reduces the risk of leakage due to improper installation. The simplified operating steps reduce the probability of human error, improving overall safety and reliability. This makes maintenance or replacement of the gate valve more convenient; operators can easily disassemble or replace it, significantly shortening maintenance time, improving equipment availability, and reducing production losses due to downtime. It also possesses strong flexibility, allowing for rapid adjustment and replacement under different operating conditions, enhancing emergency response capabilities and adaptability. Especially in applications requiring frequent adjustments or switching of operating modes, the quick-install gate valve provides greater operational flexibility.
