Description

Technical Field

[0001] The utility model relates to the technical field of tightness testing, in particular to a heating module capable of eliminating moisture from a tightness tester. Background Art

[0002] A fit tester is a device used to evaluate the sealing performance of materials or products. It uses pressure difference to test the fit of materials or products. This method usually evaluates the fit by placing the tested object in an environment with a certain pressure and observing whether there is gas leakage. It can measure the sealing contact degree and leakage of materials or products to determine their sealing quality. However, existing fit testers cannot remove water vapor in the gas when testing products, which affects the accuracy of product measurement. Utility Model Content

[0003] The utility model provides a heating module capable of eliminating moisture from a tightness tester, thereby solving the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A heating module capable of eliminating moisture from a fit tester comprises a shell, a base plate, a relay and a heating mixing block, wherein the relay and the heating mixing block are mounted on the base plate, a heating plate is mounted on the top of the heating mixing block, adapters are mounted on both ends of the heating mixing block, a power interface and a conduit joint are mounted on one end of the base plate, a temperature controller is mounted on the end of the base plate away from the power interface and the conduit joint, and the base plate is covered with a shell.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, heat dissipation holes are provided on the shell.

[0008] The beneficial effect of adopting the above further solution is that it facilitates heat dissipation inside the device.

[0009] Furthermore, a temperature sensor is installed on one side of the heating mixing block, and the temperature sensor is electrically connected to the temperature controller through a relay.

[0010] The beneficial effect of adopting the above further solution is that the internal temperature of the heating mixing block is controlled by the temperature sensor.

[0011] Furthermore, the heating plate is electrically connected to the temperature controller via a wire.

[0012] The beneficial effect of adopting the above further solution is: the heating temperature of the heating plate is controlled by the temperature controller.

[0013] Furthermore, there are two conduit joints in total, and the two conduit joints are respectively connected to the adapters at both ends of the heating and mixing block.

[0014] The beneficial effect of adopting the above further solution is that it is easy to dehumidify and dry the gas through the equipment.

[0015] The beneficial effect of the utility model is that when gas is passed into the interior of the equipment, the heating mixing block is heated by the heating plate, and when the water vapor in the heating mixing block is heated, its temperature rises, and the kinetic energy of the water vapor molecules increases, which can increase the saturated vapor pressure of the water vapor in the mixed gas block and promote the evaporation of the water vapor. Next, when the heated heating mixing block is cooled, the temperature decreases, the kinetic energy of the water vapor molecules decreases, the saturated vapor pressure decreases, and the water vapor gradually condenses into liquid water, thereby obtaining relatively dry gas.

[0025] Embodiment 1

[0026] A heating module capable of eliminating moisture in a fit tester comprises a housing 1, a base plate 4, a relay 5 and a heating mixing block 9. The relay 5 and the heating mixing block 9 are installed on the base plate 4. A heating plate 10 is installed on the top of the heating mixing block 9. The heating plate 10 is electrically connected to a temperature controller 2 through a wire. Adapters 8 are installed at both ends of the heating mixing block 9. A power interface 6 and a catheter connector 7 are installed at one end of the base plate 4.

[0027] There are two conduit joints 7, and the two conduit joints 7 are respectively connected to the adapters 8 at both ends of the heating mixing block 9. When the gas enters the interior of the device, the heating mixing block 9 is heated by the heating plate 10. When the water vapor in the heating mixing block 9 is heated, its temperature rises, and the kinetic energy of the water vapor molecules increases, which can increase the saturated vapor pressure of the water vapor in the mixed gas block and promote the evaporation of the water vapor. Next, when the heated heating mixing block 9 is cooled, the temperature decreases, the kinetic energy of the water vapor molecules decreases, and the saturated vapor pressure decreases, causing the water vapor to gradually condense into liquid water, thereby obtaining relatively dry gas. A temperature controller 2 is installed at one end of the bottom plate 4 away from the power interface 6 and the conduit joint 7, and a temperature sensor is installed on one side of the heating mixing block 9, and the temperature sensor is electrically connected to the temperature controller 2 through a relay 5. A shell 1 is provided on the bottom plate 4, and a heat dissipation hole 3 is opened on the shell 1.

[0028] A heating module based on Example 1 that can eliminate water vapor in a fit tester is in use: when gas is passed into the interior of the device, the heating mixing gas block 9 is heated by the heating plate 10, and when the water vapor in the heating mixing gas block 9 is heated, its temperature rises, and the kinetic energy of the water vapor molecules increases, which can increase the saturated vapor pressure of the water vapor in the mixed gas block and promote the evaporation of the water vapor. Next, when the heated heating mixing gas block 9 is cooled, the temperature decreases, and the kinetic energy of the water vapor molecules decreases, causing the saturated vapor pressure to drop, resulting in the water vapor gradually condensing into liquid water, thereby obtaining relatively dry gas.

[0029] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
