Technical Field

[0001] This application relates to the field of valve testing technology, and more specifically, to a plugging test device for monitoring valve sealing performance. Background Technology

[0002] Before installation, valves in equipment typically need to be sent to a third-party testing company for a valve sealing test.

[0003] Existing valve hydrostatic testing machines are mostly complex in structure, including a series of electrical components, and the testing process is time-consuming. Therefore, it is necessary to design a device that can quickly test the valve sealing performance, thereby solving the problems of long testing cycles and cumbersome operation in conventional testing.

[0004] To address the aforementioned problems, this application provides a plugging test device for monitoring valve sealing performance. Utility Model Content

[0005] The plugging test device for monitoring valve sealing performance provided in this application adopts the following technical solution:

[0006] A plugging test device for monitoring valve sealing performance includes a valve to be tested, wherein an auxiliary mechanism is provided on the outside of the valve to be tested;

[0007] The auxiliary mechanism includes two valve flanges, which are respectively installed on both sides of the valve to be tested. A valve plug plate is provided on one side of one valve flange. The valve plug plate has a through groove inside. A connecting sleeve is fixedly connected to one side of the valve plug plate. A water inlet pipe is threaded into the connecting sleeve. A handle is fixedly sleeved on the outside of the water inlet pipe. A positioning groove is provided at the bottom of the handle. A positioning block is provided inside the positioning groove. A telescopic rod is movably embedded inside the positioning block. The telescopic rod is fixedly connected to one side of the valve plug plate. A spring is fixedly connected between the positioning block and the valve plug plate. The spring is sleeved on the outside of the telescopic rod. An L-shaped plate is fixedly connected to one side of the valve plug plate. The L-shaped plate is located at the bottom of the spring. A connecting component is provided on the outside of the L-shaped plate.

[0008] Furthermore, the connecting component includes a sealing ring, which is fixedly sleeved on the outside of the water inlet pipe. The sealing ring is located between the connecting sleeve and the handle, and one side of the sealing ring is tightly fitted to the connecting sleeve.

[0009] By using the above technical solution and setting a sealing ring, the sealing performance between the water inlet pipe and the connecting sleeve can be improved, thereby preventing leakage.

[0010] Furthermore, the valve plug is fixedly connected to the valve flange on one side by multiple bolts, which are evenly distributed.

[0011] The above technical solution, by setting multiple bolts, facilitates the installation and fixing of valve plugs and valve flanges.

[0012] Furthermore, a reducing fitting is installed at the end of the water inlet pipe away from the valve to be tested, and a thin tube is fixedly connected to one end of the reducing fitting.

[0013] Furthermore, a first valve is sleeved on the outer side of one end of the thin tube, and an outlet pipe is fixedly connected to the top of the inlet pipe.

[0014] Furthermore, an L-shaped pressure measuring tube is provided in the middle of the water outlet pipe, and the L-shaped pressure measuring tube is connected to the inside of the water outlet pipe.

[0015] Furthermore, a pressure gauge is provided at the top of the L-shaped pressure measuring tube, and a second valve is sleeved on the outer side of the top of the water outlet pipe.

[0016] The above technical solution, through the cooperation of the L-shaped pressure measuring tube and the pressure gauge, facilitates the observation of pressure in the later stage, thereby improving the efficiency of use.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] First, press the positioning block and then rotate it so that it is inside the L-shaped plate and fits against the L-shaped plate. Then, screw the water inlet pipe and the connecting sleeve together. After the water inlet pipe and the connecting sleeve are installed, the positioning block can be rotated again to restore its original shape. Then, release the force applied to the positioning block so that the pressed positioning block extends into the positioning groove to position the handle, thereby enhancing the stability of use. Then, with the connecting parts, it can avoid the situation where if a part of the connecting parts has a problem, it is necessary to use external tools to unscrew the bolts one by one to replace the connecting parts. This improves the efficiency of rapid testing of valve sealing. Attached Figure Description

[0027] Example:

[0028] This application discloses a plugging test device for monitoring valve sealing performance. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The device includes the valve to be tested 1, and an auxiliary mechanism is provided on the outside of the valve to be tested 1.

[0029] The auxiliary mechanism includes two valve flanges 2, which are respectively installed on both sides of the valve 1 to be tested. A valve plug plate 3 is provided on one side of one valve flange 2. A through groove is opened inside the valve plug plate 3. A connecting sleeve 4 is fixedly connected to one side of the valve plug plate 3. A water inlet pipe 5 is threaded into the connecting sleeve 4. A handle 6 is fixedly sleeved on the outside of the water inlet pipe 5. A positioning groove is opened at the bottom of the handle 6. A positioning block 7 is opened inside the positioning groove. A telescopic rod 8 is movably embedded inside the positioning block 7. The telescopic rod 8 is fixedly connected to one side of the valve plug plate 3. A spring 9 is fixedly connected between the positioning block 7 and the valve plug plate 3. The spring 9 is sleeved on the outside of the telescopic rod 8. An L-shaped plate 10 is fixedly connected to one side of the valve plug plate 3. The L-shaped plate 10 is located at the bottom of the spring 9.

[0030] Please see Figure 1 and Figure 2 The L-shaped plate 10 has a connecting component on its outer side. The connecting component includes a sealing ring 11. The sealing ring 11 is fixedly sleeved on the outer side of the water inlet pipe 5. The sealing ring 11 is located between the connecting sleeve 4 and the handle 6. One side of the sealing ring 11 is tightly fitted with the connecting sleeve 4. By setting the sealing ring 11, the sealing performance between the water inlet pipe 5 and the connecting sleeve 4 can be improved, thereby preventing leakage.

[0031] Please see Figure 1 The valve plug 3 is fixedly connected to the valve flange 2 on one side by multiple bolts 12. The multiple bolts 12 are evenly distributed. A reducer 13 is installed at the end of the water inlet pipe 5 away from the valve 1 to be tested. A thin tube 15 is fixedly connected to one end of the reducer 13. By setting multiple bolts 12, it is easy to install and fix the valve plug 3 and the valve flange 2.

[0032] Please see Figure 1 A first valve 14 is sleeved on the outer side of one end of the thin tube 15. An outlet pipe 16 is fixedly connected to the top of the inlet pipe 5. An L-shaped pressure measuring tube 17 is provided in the middle of the outlet pipe 16. The L-shaped pressure measuring tube 17 is connected to the inside of the outlet pipe 16. A pressure gauge 18 is provided on the top of the L-shaped pressure measuring tube 17. A second valve 19 is sleeved on the outer side of the top of the outlet pipe 16. The L-shaped pressure measuring tube 17 and the pressure gauge 18 work together to facilitate the observation of pressure later, thereby improving the efficiency of use.

[0033] The implementation principle of this embodiment is as follows: When in use, first ensure that the valve 1 to be tested is closed, then press the positioning block 7 towards the side of the valve 1 to be tested, so that the positioning block 7 is located on the side of the L-shaped plate 10, and then the positioning block 7 can be rotated so that the positioning block 7 is located inside the L-shaped plate 10 and fits against the L-shaped plate 10. At this time, the positioning operation of the positioning block 7 can be completed. When the telescopic rod 8 and the spring 9 are both in a compressed state, then align the water inlet pipe 5 with the connecting sleeve 4, rotate the water inlet pipe 5 so that one end of the water inlet pipe 5 extends into the inside of the connecting sleeve 4. As the water inlet pipe 5 extends, the sealing ring 11 will fit tightly against the connecting sleeve 4. After the water inlet pipe 5 and the connecting sleeve 4 are installed, the positioning block 7 can be rotated again so that the positioning block 7 returns to its original state, and then the force applied to the positioning block 7 is released. At this time, the spring 9 will rebound without force, squeezing the positioning block 7 to extend into the positioning groove and positioning the handle 6, thereby enhancing the stability of use.

[0034] After the inlet pipe 5 is installed, open the first valve 14 and the second valve 19, and inject water into the inlet pipe 5 through one end of the thin tube 15. After water flows out from the upper end of the outlet pipe 16, close the first valve 14 and the second valve 19. At this time, the inlet pipe 5 and the outlet pipe 16 are full of water. Then connect an air compressor to one end of the thin tube 15, open the first valve 14, inject air into the inlet pipe 5, and observe the pressure value on the pressure gauge 18 at the same time. When the pressure value reaches the design requirements, observe the water leakage on the other side of the valve 1 to be tested. After completing the above test, the device can be removed by disassembling the flange connecting bolts 12 on the valve flange 2. With the above structure, if a part of the connecting component has a problem, it is necessary to use external tools to unscrew the bolts 12 one by one to replace the connecting component. This can improve the efficiency of rapid testing of valve sealing.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
