Description

Technical Field

[0001] The utility model relates to the technical field of valve testing, in particular to a fixing structure for valve testing. Background Art

[0002] A valve is a device used to control the flow of fluid, liquid or gas. It can open, close or regulate the fluid channel, thereby controlling the flow, pressure, direction, etc. of the fluid. Valves are crucial in various industrial applications, so they need to be tested to ensure that they work safely and reliably. The main purposes of valve testing include: Safety: ensuring that the valve can work normally when needed to prevent leakage, bursting or other accidents. Reliability: ensuring that the valve can maintain good working condition during long-term use to prevent failure or malfunction. Performance: ensuring that the valve can meet design requirements, such as flow, pressure, temperature and other indicators.

[0003] Currently, when testing a valve, it is necessary to fit the bottom of the valve tightly against the sealing gasket, then place the gland on the top of the valve for sealing, press the gland downward with a fixture to achieve a fixed seal on the valve, fill the valve with medium through the medium through the medium hole at the bottom of the sealing gasket, and then close the valve and apply pressure to the valve to test the valve. However, when the gland is in contact with the valve, it is impossible to position the gland. The staff only places the gland on the top of the valve, which can easily cause the valve to deviate, thereby affecting the sealing effect and the test results of the valve.

[0004] The existing patent (publication number: CN218847556U) discloses a sealing mechanism for valve testing. Through the cooperation of the valve, oil cylinder 1, splint, oil cylinder 2, block, horizontal plate, sealing gasket, curved plate, groove plate and sealing structure, the device can be used to rotate the double-headed threaded rod, the double-headed threaded rod drives the vertical block to move inward, and the vertical block drives the round rod to move inward, so that the round rod fits against the outer wall of the valve, and the pressure cover is placed on the top of the valve, which makes it easier to position the pressure cover, avoids the pressure cover and the valve from offsetting, affecting the sealing effect, and avoids affecting the test results of the valve.

[0005] In response to the above problems, the existing patent provides a solution. The existing valve test bench is provided with a fixing mechanism, which can fix the valve during testing. However, most of the current fixing mechanisms can only fix valves of the same specifications and sizes, making it inconvenient for personnel to fix the valves when testing valves of different specifications, which brings certain inconveniences to personnel when testing valves.

[0006] Therefore, a fixing structure for valve testing is proposed. Utility Model Content

The user then installs the connecting piece 42 back and drives the adjusting rod 45 to rotate by rotating the fixing plate 46, so that the movable card 44 can be translated downward to clamp and fix the valve placed inside the support block 41. The connecting rod 43 fixed on the top of the movable card 44 is used to increase the stability of the up and down translation of the movable card 44 to complete the fixation of the valve, and the user can perform valve inspection work.
