[0019] The liquid storage cup of the gasket material sealing tester of the present invention has a simple and reasonable structure, and its outer wall is transparent, which can directly visually inspect the liquid storage in the liquid storage cup from the outside, and is convenient to judge whether the liquid storage in the liquid storage cup meets the test amount; It is arranged outside the testing machine to avoid splashing of liquid storage, causing short circuit or burning of meters and meters; light weight, stable installation and good sealing effect.
[0020] The following detailed description illustrates the present disclosure by way of example but not limitation. It should be understood that various aspects of the present disclosure can be implemented individually or in combination with other aspects. This specification clearly enables those skilled in the art to make and use what we believe to be new and non-obvious improvements. It describes several embodiments, workarounds, variations, alternatives, and system applications, including what is currently considered to be the implementation of this The best mode of the invention principle described in the specification. When describing elements or features and/or embodiments, preceded by "a", "an", "the" and "said" are intended to mean having one or more of the elements or features. The terms "comprising", "including" and "having" are intended to be inclusive and mean that there are additional elements or features in addition to those specifically described.
[0021] Such as figure 2 with image 3 As shown, the liquid storage cup of the gasket material sealing tester is made of transparent polypropylene material, and the outer surface of the side wall is marked with a liquid inventory scale. The liquid storage cup is made of polypropylene material, and its weight is greatly reduced to avoid the difficulty of fixing due to its own weight and the weight of the full liquid in the test; in addition, the liquid storage cup is transparent and is marked with a liquid stock scale, which can Directly observe the liquid storage in the liquid storage cup from the outside, which is convenient for judging whether the liquid storage in the liquid storage cup meets the test amount, thereby ensuring the accuracy of the test data. The liquid storage cup can be modified from a tea cup with a volume capacity of 600ml.
[0022] Such as figure 1 As shown, the gasket material sealing test machine with the liquid storage cup mainly includes: a loading system, a testing system, a heating temperature control cooling system, a data acquisition system and a data processing system. Among them, the loading system includes: a top plate 26, a bottom plate 27, and four uprights 15 forming a pressure frame, and a manual hydraulic pump 24 (10T) fixed on the bottom plate 27, whose role is to provide corresponding pressure for the entire test; the test system Including: upper test flange 19, lower test flange 21, load sensor 16 (10T), load display 28, gas tightness test pressure gauge 5 and liquid tightness test pressure gauge 4, which are used to transfer and cushion the test load Testing of sheet tightness. The heating temperature control system includes: a temperature controller 29, an upper heating plate 18 and a lower heating plate 22, and an upper water-cooling plate 17 and a lower water-cooling plate 23 forming a cooling system, which are used for temperature control display and cooling during high temperature tests. The top plate 26, the bottom plate 27 are threadedly connected with the four columns 15, the hydraulic pump 24 is fixed on the bottom plate 27 and is movably connected with the lower water-cooling plate 23, the lower water-cooling plate 23 and the lower test flange 21, the upper test flange 19 and the upper The water-cooling plate 17 is connected by an inlay block. The data acquisition and processing system includes: an acquisition system and a computer for test data processing.
[0023] Among them, the liquid storage cup 1 is directly pinched and hung outside the control box 25 of the testing machine panel with the fixing bolts 13, the cup bottom of the liquid storage cup 1 and the joint assembly 30 of the testing machine are sealed and connected by a sealant, and the joint assembly 30 is then connected by soft The pipe 31 is connected into the device. The liquid storage cup is arranged outside the panel control box 25 of the testing machine, which is convenient for filling liquid, and is not limited to the distance between the equipment and the wall. At the same time, avoiding splashing of liquid storage, causing circuit short circuit or burning of meters and meters; the bottom of the liquid storage cup 1 and the joint assembly 30 of the testing machine are sealed and connected with a sealant to have a good sealing effect.
[0024] The gasket sealing tester can perform gas and liquid sealing tests. During the gas seal test, open valve B8, valve C9 and valve D14, then open valve A10 to fill the pipeline with test gas, close valve D14, adjust the pressure reducing valve to make the pressure gauge reading reach the required pressure for the test, and then close Air valve A10; close air valve B8 and air valve C9, fine-tune valve D14 and make the side pressure gauge liquid column reach an appropriate height, start the computer test program for leak rate test after stable for 2 minutes, and end the test after the predetermined test time, the computer will automatically Perform data processing; at the end of the test, first close the cylinder and the pressure reducing valve, open the gas valve B8 and the gas valve C9, and then slowly open the valve D14 to release the gas in the pipeline. Unload and take out the sample.
[0025] To carry out the liquid sealing test, first open the liquid valve C6 and the valve D14 to make the pipeline communicate, then open the liquid valve A2 that controls the liquid storage cup 1, and close the valve D14 after filling the pipeline with the test liquid. After the liquid is filled, the liquid valve A2 is closed, so that the liquid in the liquid storage cup 1 can be controlled. At the same time, close the liquid valve C6 to isolate the atmosphere from the pipeline. At this time, open the liquid valve B7 to make the pressure source N2 enter the pipeline. After adjusting the test pressure to the required value, close the liquid valve B7, and start the test software program for testing after 2 minutes of stability. Select liquid when selecting the medium type in the program test interface. After the test, the computer will automatically process the data. And close the pressure source N2, open the liquid valve B7 and the liquid valve C6, and then slowly open the valve D14 to allow the liquid in the pipeline to flow out. Unload and take out the sample.
[0026] In summary, the structure of the liquid storage cup of the gasket material sealing tester is simple and reasonable, and its outer wall is transparent, which can directly visually inspect the liquid storage in the liquid storage cup from the outside, which is convenient to judge whether the liquid storage in the liquid storage cup meets the test amount; The cup is arranged on the outside of the testing machine to avoid splashing of the liquid storage, causing short circuit or burning of the instrument and electric meter; light weight, stable installation, and good sealing effect.
[0027] The above-disclosed are only a few specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be thought of by those skilled in the art should fall into the protection scope of the present invention.
