[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium (temperature, pressure, and flow). Based on their function, they can be divided into shut-off valves, check valves, and regulating valves. After valve production and assembly, various performance tests, such as sealing, are required.

[0003] Some existing test devices for instrument valves usually perform manual inspections one by one when testing the air tightness of instrument valves. The steps are roughly as follows: first, the pipeline and the instrument valve are connected, and then air is introduced into the interior of the instrument valve through an air pump. Subsequently, it is placed in water to observe whether bubbles are generated, so as to judge the sealing performance of the instrument valve. However, in actual use, the manual test inspection method is inefficient and inconvenient for continuous inspection of the instrument valve, resulting in a long time and low test efficiency. In view of this, we propose an instrument valve test device to solve the above problems. Utility Model Content

The first connecting block 10 has a first slot 11 extending to the right and front and rear sides. The first sliding groove 7, the second sliding groove 8 and the third sliding groove 9 on the left side are rotatably connected to the first threaded rod 12. The first connecting block 10 is threadedly sleeved on the outer surface of the first threaded rod 12. The right guide groove 6 has a second threaded rod 14 rotatably connected to the inside. The right guide groove 6 has two second connecting blocks 15 slidably connected to the inside. The second connecting block 15 has a second slot 16 extending to the left surface and the upper and lower surfaces. The second connecting block 15 is threadedly sleeved on the outer surface of the second threaded rod 14. There are two positioning components 17 inside the groove 4. When the staff needs to perform an airtightness test on the instrument valve, they first position and fix the workpiece through the positioning component 17, and then operate the test component 2 and the instrument valve to connect. Subsequently, the first threaded rod 12 is rotated to drive the first connecting block 10 to slide inside the first sliding groove 7, the second sliding groove 8 and the third sliding groove 9, thereby driving the positioning component 17 on the upper side of the through groove 5 to move downward synchronously, and then the workpiece on the upper part of the positioning component 17 is lowered to the inside of the water tank 3. After the subsequent inspection is completed, the positioning component 17 is reset, and then the second threaded rod 14 is rotated. At this time, the rotation of the second threaded rod 14 will drive The second connecting block 15 slides inside the right guide groove 6 and drives the positioning assembly 17 to slide inside the right guide groove 6, and finally the other positioning assembly 17 is located on the upper side of the through groove 5.

The setting of the connector 204 facilitates connection with the instrument valve to be tested. A storage component 205 is provided on the front side of the C-shaped frame 201. The staff operates the connector 204 to thread the instrument valve, and then starts the air pump inside the C-shaped frame 201, and then the internal ventilation of the instrument valve can be achieved.

[0029] Furthermore, the storage component 205 includes a fixing plate 2051 fixedly connected to the front surface of the C-shaped frame 201, and a stick body 2052 is arranged between the two fixing plates 2051 through an axis. The setting of the storage component 205 is convenient for the staff to adjust according to the required length of the gas pipe 203.

[0030] Working principle:

[0031] When the instrument valve test device is in use, it is positioned and fixed by the positioning assembly 17, and then the test assembly 2 and the instrument valve are connected. Subsequently, the rotation of the first threaded rod 12 drives the first connecting block 10 to slide inside the first sliding groove 7, the second sliding groove 8 and the third sliding groove 9, thereby driving the positioning assembly 17 located on the upper side of the through groove 5 to move downward synchronously, and then the workpiece on the upper part of the positioning assembly 17 is lowered to the inside of the water tank 3. After the subsequent inspection is completed, the positioning assembly 17 is reset, and then the second threaded rod 14 is rotated. At this time, the rotation of the second threaded rod 14 will drive the second connecting block 15 to slide inside the right guide groove 6, and then drive the positioning assembly 17 to slide inside the right guide groove 6, and finally make the other positioning assembly 17 located on the upper side of the through groove 5. At this time, the staff can perform airtightness testing on the workpiece on the positioning assembly 17 located on the upper side of the through groove 5, and replace the workpiece on the upper side of the other positioning assembly 17, and finally achieve the continuity of the test.
