TECHNICAL FIELD
[0001] The utility model relates to thermal insulation material water absorption test technical field especially a kind of thermal insulation material water absorption test device with automatic water replenishing function. BACKGROUND
[0002] Thermal insulation material water absorption test device is a special equipment for determining the water absorption performance of thermal insulation materials. This device simulates the water absorption of thermal insulation materials in actual use environment to evaluate their waterproof performance and durability. Thermal insulation material water absorption test device is usually composed of multiple components, including immersion container, sample support frame, weighing system, control system, etc. These components work together to ensure the accuracy and reliability of the test. The immersion container is used to hold the water or solution for immersion and ensure that the sample is completely immersed. The size and shape of the immersion container should be customized according to the size and shape of the sample to ensure the accuracy of the test.
[0003] The existing thermal insulation materials, such as extruded board, molded board, polyurethane board, and vitrified microbeads, have the characteristics of small density, light weight, and large volume.

The top of the support is provided with a weighing mechanism, and the immersion cylinder is provided with a water-permeable hanging cylinder. The hanging cylinder is suspended on the weighing mechanism. It can completely fix the lightweight thermal insulation material sample in water for immersion, thereby limiting the lightweight thermal insulation material sample from floating out of the water surface, allowing the sample to fully soak and absorb water, and improving the accuracy and efficiency of the water absorption rate test.

[0027] Please refer toFigures 1 to 4 The application discloses a heat preservation material water absorption test device with an automatic water supplement function.
[0028] The water supplement mechanism comprises a water supplement tank 3 which is fixed to the upper end of the left side of the test box 1, the side wall of the water supplement tank 3 is communicated with a mounting pipe 31, the outer wall of the mounting pipe 31 is communicated with a drain pipe 32, the horizontal direction of the inner wall of the mounting pipe 31 is fixed with a fixing piece 33, the lower surface of the inside of the mounting pipe 31 is fixed with an ejection spring 34, the upper surface of the ejection spring 34 is connected with a sealing valve core 35 which penetrates the upper end of the mounting pipe 31, the upper surface of the sealing valve core 35 is hingedly connected with a hinge rod 36 which is hingedly connected with the mounting pipe 31, the tail end of the hinge rod 36 is fixed with a threaded pipe 37, the lower end of the inside of the threaded pipe 37 is threadedly connected with a screw rod 38, the lower surface of the screw rod 38 is fixed with a floating ball 39, the fixing mechanism comprises a mounting piece 4 which is fixed to the upper end of the test box 1, and the upper surface of the mounting piece 4 is fixed with a stepping motor 41 through bolts.
[0029] By adopting the above technical scheme, before the heat preservation material water absorption test device is used, the test box 1 is first placed in a suitable position, and the heat preservation material to be tested is first weighed and recorded, when the water level in the test box 1 drops during long-time soaking, the floating ball 39 floating on the water surface synchronously drops, so that the screw rod 38 drives the threaded pipe 37 to drop, at this time, the sealing valve core 35 vertically moves under the cooperation of the hinge rod 36, and the sealing valve core 35 is opened under the elastic effect of the ejection spring 34, the lower surface of the sealing valve core 35 is separated from the through hole on the fixing piece 33, the flow of the water supplement tank 3 is released, so that the water stored in the water supplement tank 3 is discharged into the test box 1 through the mounting pipe 31 and the drain pipe 32, and the automatic water supplement function is realized, when the water level reaches a position, the floating ball 39 floating on the water surface synchronously resets the sealing valve core 35, after the test is completed, the water can be discharged by opening the drain valve 2, and the water absorption of the heat preservation material can be detected by comparing the weight of the heat preservation material after the test with the weight before the test.
[0030] Specifically, as shown in Figure 1 and Figure 2As shown, the output shaft of the stepper motor 41 is fixed with a threaded rod 42, the end of the threaded rod 42 is rotatably connected to the inner wall of the mounting piece 4 through a bearing, the outer surface of the threaded rod 42 is slidably connected with a mounting frame 43, the inside of the mounting frame 43 is provided with two groups of fixed bolts 44, the ends of the two groups of fixed bolts 44 are fixed with clamping plates 45, and the cleaning mechanism comprises fixed plates 5.
[0031] By adopting the above technical scheme, the heat preservation material is placed at the lower end of the mounting frame 43, and the fixed bolts 44 are tightened to drive the clamping plates 45 to clamp the heat preservation material.

When immersed for a long time, the water level in the test tank 1 decreases, and the float ball 39 floating on the water surface synchronously decreases, so that the screw rod 38 drives the threaded pipe 37 to descend. Under the cooperation of the hinged rod 36, the sealing valve core 35 moves vertically, and under the elastic action of the ejection spring 34 itself, it will assist the sealing valve core 35 to open. The lower surface of the sealing valve core 35 is separated from the through hole of the fixed part 33, the flow of the water storage tank 3 is removed, so that the water stored in the water storage tank 3 is discharged into the test tank 1 through the installation pipe 31 and the drain pipe 32, realizing the function of automatic water replenishment. When the water level reaches the position, the float ball 39 floating on the water surface will reset the sealing valve core 35.
