Description

Technical Field

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

[0002] Valves are control components in fluid conveying systems. They have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems can be used to control the flow of various types of media such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are important components in fluid conveying systems and need to be pressure tested on a valve pressure test bench before use.

[0003] When the existing valve pressure test bench performs continuous pressure tests on multiple valves, the valve that has completed the previous pressure test is usually removed, and then the next valve is placed to continue the pressure test. During the process of replacing the valve, the valve pressure test bench does not perform the pressure test, which wastes time and reduces the working efficiency of the valve pressure test bench. For this reason, we propose a valve pressure test bench. Utility Model Content

[0026] The utility model provides a valve pressure testing platform, which drives a rotating platform at the upper end to rotate by a motor, thereby driving the valve placed on the rotating platform to rotate. When a plurality of valves are pressure tested continuously, after the pressure test of one valve is completed, the next valve can be rotated to the pressure testing position by rotating the rotating platform to continue the pressure test, thereby saving the time for replacing the valve and improving the working efficiency of the pressure testing platform.

[0029] The rotating placement assembly 200 includes a motor 210 disposed at the middle of the upper end of the workbench 110, a rotating table 220 vertically fixed at the output end of the motor 210, and a lower pressure plate 230 disposed at the outer side of the middle of the upper end of the rotating table 220. The lower pressure plate 230 is provided with a plurality of lower pressure plates 230, and the plurality of lower pressure plates 230 are distributed in a ring around the center of the rotating table 220. Preferably, in this embodiment, a plurality of limiting rods 221 are vertically fixed at the outer side of the middle of the lower end of the rotating table 220, and a limiting groove 111 is provided at the outer side of the middle of the upper end of the workbench 110, and the outer wall of the limiting rod 221 is fitted with the inner wall of the limiting groove 111. When the rotating table 220 rotates with the motor 210, the limiting rod 221 at the lower end thereof rotates synchronously in the limiting groove 111 of the workbench 110, and the rotating limiting rod 221 generates a certain friction force with the limiting groove 111, thereby ensuring the stability of the rotating table 220 during the rotating process.

[0030] The pressure test assembly 300 includes a hydraulic push rod 310 vertically fixed on the fixed plate 130 and an upper pressure plate 320 vertically installed at the lower end of the hydraulic push rod 310. Preferably, in this embodiment, a clamping column 231 is fixed to the middle part of the lower end of the lower pressure plate 230, and a clamping groove 222 is provided at the upper end of the rotating table 220. The clamping column 231 is clamped with the clamping groove 222. The lower pressure plate 230 is clamped on the rotating table 220 under the action of the clamping column 231. The operator can manually remove the lower pressure plate 230 at a later stage so as to disassemble and replace the lower pressure plate 230 according to the size of the valve actually tested. A placement groove is provided at the upper end of the lower pressure plate 230, and a rubber pad is fixed in the placement groove. The placement groove serves as a limit placement for the valve to prevent the valve from displacement during rotation. The rubber pad arranged in the placement groove plays a sealing role for the lower side of the valve that needs to be pressure tested. A sealing pad 321 is fixed to the lower end of the upper pressure plate 320. The sealing pad 321 is made of rubber. The sealing pad 321 arranged at the lower end of the upper pressure plate 320 plays a sealing role for the upper side of the valve that needs to be pressure tested. A connecting portion 322 is provided in the middle of the upper end of the upper pressure plate 320. The connecting portion 322 is threadedly connected to the hydraulic push rod 310. The upper pressure plate 320 is threadedly installed on the lower end of the hydraulic push rod 310 under the action of the connecting portion 322. The operator can disassemble and replace the upper pressure plate 320 according to the size of the valve actually tested.

[0031] Combination Figure 1-Figure 3, a valve pressure testing platform of the present embodiment is specifically used as follows: an operator places the valve to be pressure tested on the lower pressure plate 230 at the upper end of the rotating platform 220, and the placement groove provided on the lower pressure plate 230 serves as a limit for the valve to prevent the valve from being displaced during the rotation. After the placement is completed, the upper pressure plate 320 is pushed downward by the hydraulic push rod 310 to squeeze the valve, and then the valve is pressure tested. After the pressure test of the valve is completed, the hydraulic push rod 310 drives the upper pressure plate 320 to rise, and the motor 210 is started. The motor 210 drives the rotating platform 220 at the upper end to rotate, and then drives the valve placed on the rotating platform 220 to rotate, and the next valve on the rotating platform 220 is rotated to the pressure test position to continue the pressure test, thereby saving the time for replacing the valve and improving the working efficiency of the pressure testing platform.
