Description

Technical Field

[0001] The present invention relates to the technical field of valve detection, in particular to a reversible valve maintenance and testing integrated device. Background Art

[0002] In terms of use on ships, they are equipped with multiple valves. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems. The valve body needs to be flipped to a certain angle during the disassembly and assembly process. After the valve assembly is completed, it is necessary to conduct air pressure sealing performance tests, controllability tests and other tests to verify whether the valve is qualified.

[0003] After searching, the application with patent number 202122347584.8 discloses a reversible valve maintenance and testing integrated device, including a workbench, a pillar is provided on one side of the top of the workbench, a support rod is provided on one side of the top of the pillar, a collar is fixedly connected to the outer wall of the support rod close to the side of the pillar, the collar is slidably connected to the pillar, and a slide groove is provided on the top of the inner wall of the support rod. The utility model drives the bevel gear to rotate by the output shaft of the driving motor, so that the steering gear engaged with the outer wall of the bevel gear drives the turntable to rotate, thereby adjusting the position of the valve, rotating the screw rod to move the mounting plate in the relative direction, thereby driving the two fastening plates to clamp and fix the valve, and the rotating motor drives the mounting plate to rotate, so that the valve between the two fastening plates is flipped, and the valve can be flipped in different directions. The valve can be fixed, rotated, and flipped, thereby improving the maintenance efficiency of the equipment;

[0004] In the field of industrial fluid control, the air tightness of valves is directly related to the safety and stability of the system, and is a core indicator to ensure the normal operation of key links such as fluid transportation and pressure regulation. As an important process for valve quality control, air tightness testing is crucial to the integrity and effectiveness of the testing process for valve performance evaluation. However, although the existing application documents have achieved the valve flipping function through the limit assembly, there is an obvious technical gap in the subsequent air tightness testing link. On the one hand, the specific air tightness testing method has not been disclosed, making it difficult to ensure that the valve sealing performance is accurately evaluated; on the other hand, there is a lack of technical solutions for valve flipping and dynamic position adjustment during the testing process, resulting in the inability to conduct comprehensive testing on different sealing surfaces of the valve, seriously affecting the accuracy and reliability of air tightness testing. How to improve the valve air tightness testing process and achieve precise flipping and position adjustment of the valve during the testing process has become a technical problem that needs to be solved urgently.

[0005] Therefore, we proposed a reversible valve maintenance and testing integrated device. Summary of the Invention

The air tightness of the valve is tested by the air supply of the air pump 2. At the same time, the structure is simple and the operation is less complicated, which solves the problem that the existing device is difficult to perform efficient air tightness testing on the valve to be tested according to needs.

[0038] Example 2:

[0039] The air pipe 4 is connected to the hose, and the air pipe 4 is fixedly connected to the input and output ends of the valve through the valve cover plate 5 at its outer end; wherein, the setting of the air pipe 4 hose facilitates the connection of the air pump 2 and the pressure detection gauge 3 to the input and output ends of the valve to be tested according to needs, ensuring the connectivity of the valve and the subsequent air tightness detection effect when its position changes.

[0040] The main body of the adjustment component 7 is the adjustment frame 71, which is a semicircular frame, and the center of the bottom of the adjustment component 7 is connected to the top of the output shaft of the cylinder component 6; wherein, the shape of the adjustment frame 71 is convenient for sliding the limit assembly 8 thereon, thereby facilitating the adjustment effect of the valve limited inside the limit assembly 8.

[0041] Slide cards 73 are fixedly welded at the end corners on both sides of the adjustment component 7. The slide card 73 is a T-shaped card. A side seat 9 is fixedly installed on the inner side of the test frame seat 1 in an opposite position, and the side seat 9 is provided with a card seat 10 with a top opening and adapted to the specifications of the slide card 73.
