Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauge detection, in particular to a gas-liquid pressurizing device for pressure gauge detection. Background Art

[0002] Gas-liquid boost testing is a common method for pressure gauge testing. A gas-liquid booster pump converts gas pressure into a higher liquid pressure, providing the test pressure source for the pressure gauge. This method generates high and stable pressure, meeting the testing needs of pressure gauges with varying ranges and accuracy requirements. For example, some high-precision, high-range pressure gauges require a higher pressure input to accurately test their performance across the full range. Gas-liquid boost testing effectively provides this pressure condition.

[0003] At present, conventional gas-liquid booster pumps have only one interface. This feature brings great inconvenience when faced with the situation where multiple pressure gauges need to be tested simultaneously. In actual industrial production and testing scenarios, it is often necessary to test multiple pressure gauges at the same time. For example, in a large chemical plant, there may be multiple pressure gauges in different locations that need to be calibrated and tested at the same time to ensure the pressure monitoring accuracy of the entire system. However, since the gas-liquid booster pump has only one interface, only one pressure gauge can be connected for testing at a time, which leads to low detection efficiency. In order to test multiple pressure gauges, a gas-liquid booster pump with a single interface needs to connect the pressure gauges one by one for testing. In this process, each time a pressure gauge is replaced, a series of operations such as connection, pressurization, testing, depressurization, and disassembly are required. These operations are not only time-consuming, but the frequent connection and disassembly processes may introduce human errors, affecting the accuracy of the test results.

[0004] In view of this, this application is hereby filed. Utility Model Content

The positioning component includes

[0028] A plurality of sliding rods 9 are radially slidably arranged on the outer wall of the butt joint socket 4;

[0029] The fixing ring 11 extends radially and is fixed on the outer wall of the butt joint socket 4. A mounting shell 12 is provided on the outer peripheral wall of the fixing ring 11, and a gear ring 14 is rotatably mounted on the top surface of the fixing ring 11.

[0030] The gear 15 is rotatably mounted on the top surface of the fixed ring 11 and is meshed with the gear ring 14 . The sliding rod 9 is provided with teeth 16 that mesh with the gear 15 .

[0031] Specifically, the gas-liquid booster pump 1, the detection tube 2 and the docking tube socket 4 can be used together to simultaneously detect multiple pressure gauges 5 to be tested, overcoming the limitation that the traditional gas-liquid booster pump 1 has only one interface. With multiple interfaces, this design can simultaneously connect multiple pressure gauges 5 to be tested for testing, which greatly shortens the detection time compared with the traditional method of detecting one by one through a single interface.

[0032] See Figure 3 An adjusting screw 21 is threadedly connected to the side wall of one of the mounting shells 12 , and one end of the adjusting screw 21 extends to the interior of the mounting shell 12 and is connected to the sliding rod 9 .

[0033] Specifically, by rotating the adjusting screw 21, it can be driven to move along the mounting shell 12. During the displacement of the adjusting screw 21, the sliding rod 9 can be pushed to slide toward the inside of the docking pipe seat 4, thereby conveniently fixing the pressure gauge 5 to be tested inside the docking pipe seat 4.

[0034] See Figure 2 The sliding rod 9 extends to one end of the interior of the butt joint 4 and is fixedly connected to a clamping plate 10. The clamping plate 10 is an arc-shaped plate structure, and a non-slip pad is provided on the side of the clamping plate 10 away from the sliding rod 9.

[0035] Specifically, the clamping plate 10 can increase the contact area between the sliding rod 9 and the pressure gauge to be measured 5, thereby improving the stability of fixing the pressure gauge to be measured 5.

[0036] See Figure 4 The interior of the butt joint socket 4 is symmetrically provided with an annular groove, and a sealing airbag 6 is embedded and installed inside the annular groove. A sealing lip is integrally formed on the inner wall of the sealing airbag 6.

[0037] Specifically, the provided sealing airbag 6 has a sealing effect, thereby preventing gas leakage during the detection process.

[0038] See Figure 4 A sealed air cavity 17 is provided on the side wall of the butt joint socket 4 , and a vent pipe 18 communicating with the air cavity 17 is provided on the sealed airbag 6 .

[0039] Specifically, the air cavity 17 and the vent tube 18 cooperate to inflate the interiors of the two sealed airbags 6 synchronously, thereby improving detection efficiency.

[0040] See Figure 3An air supply bag 20 is installed inside the mounting shell 12 , and an air flow pipe 19 is connected to the air supply bag 20 . An end of the air flow pipe 19 away from the air supply bag 20 is connected to the air cavity 17 .

[0041] Specifically, air can be supplied to the interior of the air cavity 17 through the cooperation of the air flow tube 19 and the air supply airbag 20, and then transported to the interior of the sealing airbag 6 through the vent tube 18. The sealing airbag 6 expands after inflation and can be tightly fitted with the pressure gauge 5 to be measured, thereby improving the overall sealing performance.

[0042] See Figure 4 A slide seat 13 is slidably installed inside the mounting shell 12 , one side of the air supply airbag 20 is fixedly connected to the side wall of the slide seat 13 , and the other side of the air supply airbag 20 is connected to the inner wall of the mounting shell 12 .

[0043] Specifically, the sliding seat 13 can be linked to the sliding rod 9 to squeeze the air supply airbag 20, thereby achieving the effect of automatically inflating the interior of the sealing airbag 6.

[0044] See Figure 4 A mounting tube 7 is installed on the side wall of the docking tube seat 4, one end of the mounting tube 7 extends to the inside of the docking tube seat 4 and is located between the two sealing airbags 6, and one end of the mounting tube 7 extends to the outside of the docking tube seat 4 and is fixedly connected to a whistle tube 8.

[0045] Specifically, when a gas leak occurs, the leaked gas will be discharged from the installation pipe 7, and during the discharge process, the whistle pipe 8 will be affected by the airflow to produce a whistle sound, reminding the staff that there is a leak, thereby avoiding leakage during the detection process that affects the detection accuracy.

[0046] Working principle: When in use, insert the pressure gauge 5 to be measured into the interior of the docking pipe seat 4, and drive it to move along the mounting shell 12 by rotating the adjusting screw 21. During the displacement of the adjusting screw 21, the sliding rod 9 can be pushed to slide toward the interior of the docking pipe seat 4, so that the pressure gauge 5 to be measured can be conveniently fixed to the interior of the docking pipe seat 4. During the movement, the sliding rod 9 drives the gear 15 meshing with it to rotate through the teeth 16, and the gear 15 drives the gear ring 14 to rotate, and the gear ring 14 drives the remaining gears 15 to rotate, and the remaining gears 15 drive the remaining sliding rods 9 to close synchronously toward the interior of the docking pipe seat 4. During the sliding process of the sliding rod 9, the air supply gas will be squeezed Bag 20, the gas inside the air supply bag 20 will enter the interior of the air cavity 17 through the air flow pipe 19, and then be transported to the interior of the sealed air bag 6 by the air cavity 17 and the ventilation pipe 18. The sealed air bag 6 expands and fits tightly against the outer wall of the pressure gauge 5 to be tested, and the connection gap between the docking pipe seat 4 and the pressure gauge 5 to be tested is sealed to avoid gas leakage during the detection process. After the pressure gauge 5 to be tested is fixed, gas is transported to the inside of the detection tube 2 through the gas-liquid booster pump 1, and the gas can be in contact with the docking pipe seat 4 and the pressure gauge 5 to be tested. By comparing the pressure gauge 5 to be tested with the control pressure gauge 3, the effect of synchronous detection of multiple pressure gauges 5 to be tested is achieved.
