Technical Field
[0001] This utility model relates to the technical field of a multi-band anti-vibration actuator for a shut-off valve in a refrigeration system, specifically a multi-band anti-vibration actuator for a shut-off valve in a refrigeration system. Background Technology
[0002] Gate valves, also known as stop valves, are among the most widely used valves. Their popularity stems from the low friction between the sealing surfaces during opening and closing, resulting in durability. They also have a small opening height, are easy to manufacture and maintain, and are suitable for both low and medium pressures as well as high pressures. The closing principle of a gate valve relies on the pressure of the valve stem to ensure a tight seal between the valve disc sealing surface and the valve seat sealing surface, thus preventing the flow of media.
[0003] In actual operation, the existing gate valves are installed in different locations with different connecting pipelines. In locations with high vibration intensity, the gate valves will be affected by continuous vibration, which will affect their various performance characteristics, such as sealing performance and pressure bearing performance, thus shortening their service life.
[0004] Therefore, a multi-frequency anti-vibration actuator for refrigeration system shut-off valves is needed to improve the above-mentioned problems. Utility Model Content

A first sliding rod 406 is provided inside the first limiting seat 404, and a second sliding rod 407 is provided inside the second limiting seat 405. A first shock absorber 408 is provided at the left end of the first sliding rod 406, and a second shock absorber 409 is provided at the right end of the second sliding rod 407. A first buffer rod 410 is rotatably provided on the right side of the front of the first sliding rod 406, and a second buffer rod 411 is rotatably provided on the left side of the back of the second sliding rod 407. A connecting block 412 is rotatably provided between the upper ends of the first buffer rod 410 and the second buffer rod 411. A connecting rod 413 is provided at the upper end of the connecting block 412, and an anti-vibration plate 414 is provided at the upper end of the connecting rod 413.
[0028] The first connecting flange 2 and the second connecting flange 3 are evenly provided with connecting holes. Sealing gaskets made of rubber are provided on both flanges, increasing sealing performance and effectively preventing media leakage. Mounting holes are provided at the corners of the base surface of the base 401. The base surface of the anti-vibration plate 414 is fixedly connected to the bottom of the gate valve body 1. Through holes are provided on the base surfaces of the first anti-vibration seat 402 and the second anti-vibration seat 403 corresponding to the connecting rod 413, and the connecting rod 413 is slidably connected to the through groove. Sliding grooves are provided inside the first limiting seat 404 and the second limiting seat 405 corresponding to the first sliding rod 406 and the second sliding rod 407, respectively, and the first sliding rod 406 and the second sliding rod 407 are slidably connected to the sliding grooves. The first limiting seat 404 and the second limiting seat 405 can accommodate the first sliding rod 406 and the second sliding rod 407. The moving rod 406 and the second sliding rod 407 are limited. When the first buffer rod 410 and the second buffer rod 411 rotate, the first sliding rod 406 and the second sliding rod 407 can move on the same horizontal line. The outer ends of the first shock absorber 408 and the second shock absorber 409 are fixedly connected to the left and right sides of the inner walls of the first vibration-damping seat 402 and the second vibration-damping seat 403, respectively. The inner ends of the first shock absorber 408 and the second shock absorber 409 are fixedly connected to the outer ends of the first sliding rod 406 and the second sliding rod 407, respectively.

[0029] The working process of this utility model is as follows: Using the multi-band anti-vibration actuator for the shut-off valve in the refrigeration system designed in this scheme, when vibration occurs, the shut-off valve moves downwards. This downward movement of the shut-off valve drives the connecting rod 413 to move, which in turn drives the connecting block 412 to move. Since the upper ends of the first buffer rod 410 and the second buffer rod 411 are rotatably connected to the connecting block 412, when the connecting block 412 moves, the upper ends of the first buffer rod 410 and the second buffer rod 411 rotate. Since the lower ends of the first buffer rod 410 and the second buffer rod 411 are rotatably connected to the first sliding rod 406 and the second sliding rod 407, respectively, the first buffer rod 410 and the second buffer rod 411... When the upper end of rod 411 rotates, it drives the lower ends of the first buffer rod 410 and the second buffer rod 411 to rotate. Since the first sliding rod 406 and the second sliding rod 407 are slidably connected to the first limiting seat 404 and the second limiting seat 05 respectively, when the lower ends of the first buffer rod 410 and the second buffer rod 411 rotate, they drive the first sliding rod 406 and the second sliding rod 407 to move outward respectively. The first sliding rod 406 and the second sliding rod 407 squeeze the first shock absorber 408 and the second shock absorber 409 respectively. The first shock absorber 408 and the second shock absorber 409 can dampen and buffer the shut-off valve, making its vibration resistance better and thus allowing it to be used better.
