Description

Technical Field

[0001] The utility model belongs to the technical field of pressure testing, and more specifically, relates to a tank pressure testing device. Background Art

[0002] The tank pressure testing device mainly applies a certain pressure to the tank to simulate the pressure environment that the tank may encounter in actual use, thereby testing the tank's pressure bearing capacity, sealing performance, and whether there is potential leakage or rupture risk. The device can monitor and record parameters such as pressure changes and temperature changes during the test in real time, providing an important basis for the quality assessment and safe use of the tank.

[0003] In the prior art, the authorization publication number "CN216284594U" discloses a "pressure tank strength testing device with a quick connection structure"; it includes a supporting base plate, the front and rear ends of the upper outer surface of the supporting base plate are fixedly connected to fixed curved plates, the middle position of the upper outer surface of the fixed curved plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a rotating shaft, the upper upper position of the outer surface of the rotating shaft is fixedly connected to a first rotating shaft, the outer surface of the first rotating shaft is movably connected to a belt, the front and rear ends of the inner part of the belt are both movably connected to a second rotating shaft, the inner part of the second rotating shaft is fixedly connected to a spiral rod, a pressure plate is movably connected between the four spiral rods, and the front and rear ends of the upper outer surface of the fixed curved plate are both fixedly connected to two fixed rods. The utility model can quickly fix the pressure tank through structural coordination, which is convenient for staff to test the pressure tank.

[0004] The above-mentioned "a pressure tank strength testing device with a quick connection structure" still has some shortcomings. For example, during the pressure test of the existing tank, the pressure test is often carried out directly. Temperature is an important factor affecting the material performance and safety of the pressure vessel. Failure to carry out the temperature increase test will reduce the comprehensiveness of the test. At the same time, the temperature is difficult to reduce after the temperature test, and a long period of natural cooling is required, which prolongs the test time. At the same time, the shaking during the pressure test will cause the reading of the pressure measuring instrument to be unstable, resulting in large measurement errors.

[0005] For this reason, a tank pressure testing device is proposed here to solve the above-mentioned problems. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a tank pressure testing device to solve the problems proposed in the above background technology that shaking during the pressure test will cause unstable readings of the pressure measuring instrument, and that not performing a temperature increase test will reduce the comprehensiveness of the test, and that the temperature is difficult to lower after the temperature test.

By circulating the cooling liquid along the inner side of the circulation box 605, the insulation layer 604 can be cooled evenly and quickly.

[0036] The specific usage and function of this embodiment: During the daily operation of the tank pressure testing device, first, after the motor body 5010 is started, the right threaded rod 509 is driven to rotate by the motor body 5010. Through the connection of the connecting rod 508, the right threaded rod 509 and the left threaded rod 507 at both ends of the connecting rod 508 can be synchronously driven to rotate, and when the left threaded rod 507 rotates, it will be movably connected to one side of the fixed plate 5013 through the bearing disk 5012, and the bearing disk 5012 is supported by the fixed plate 5013, which can improve the rotation stability of the left threaded rod 507.

At this time, the two sliding blocks 505 will move horizontally toward each other, and through the connection between the side fixing rod 504 and the connecting frame 503, the two clamping frames 502 are driven to move along the two sides of the support column 2, and fit and clamp the two sides of the support column 2. At the same time, during the movement of the sliding block 505, it will slide along one side of the side sliding rail 5014 through the side sliding frame 5011, which can improve the stability of the sliding block 505 during the movement process. By stably clamping the support column 2, the stability of the support column 2 during the support process can be improved, thereby reducing the shaking of the main tank body 1 during the pressure test and improving the accuracy of the test;

[0038] After the test is completed, the heating box 603 is closed and the water pump body 609 is started. The water pump body 609 can drive the coolant in the liquid storage tank 6010 to flow along the side liquid inlet pipe 607 to the circulation box 605, and then flow back to the liquid storage tank 6010 through the bottom liquid outlet pipe 608 at the bottom of the circulation box 605 to form a cycle. The coolant circulates along the inner side of the circulation box 605, which can evenly and quickly cool the insulation layer 604. The insulation layer 604 fits the main tank body 1, so the main tank body 1 can be quickly cooled, thereby improving the cooling efficiency of the main tank body 1 and shortening the time for the pressure test of the main tank body 1.
