A heat insulation layer and a heat conductive layer are arranged in the shell. The heat insulation layer and the heat conductive layer cover the four sides and the bottom of the shell, and the heat conductive layer is located on the inner side of the heat insulation layer and encloses to form a heating space for holding liquid.

The smoke conveying component includes a smoke conveying pipe passing through the heating space.

[0004] Regarding the above-mentioned related technologies, the applicant believes that when using a constant temperature water tank in a plateau environment, due to the low ambient air pressure, the temperature of the constant temperature water tank cannot meet the use requirements during use, affecting the use effect of the constant temperature water tank. Summary of the Invention

[0005] In order to improve the use effect of a constant temperature water tank, the present application provides a plateau type pressure constant temperature water tank.

[0007] The tank body is arranged on the base, the inner container is installed on the tank body, and the top end of the inner container extends out of the inner cavity of the tank body;

[0008] The sealed box cover is buckled on one side of the opening of the inner container, and the sealed box cover and the inner container form a sealed cavity;

[0009] The heating component is used to heat the medium in the sealed cavity.

[0010] By adopting the above technical solution, due to the rising altitude of the plateau environment, the atmospheric pressure is low, so that the temperature in the constant temperature water tank cannot meet the use requirements. When using the constant temperature water tank in the plateau environment, first, fill the inner tank with the medium, then place the object to be tested in the inner tank, and then buckle the sealed box cover on the inner tank, so that the inner tank and the sealed box cover form a sealed cavity, and then heat the medium in the sealed cavity through the heating component. As the temperature of the medium in the sealed cavity increases, the pressure in the sealed cavity increases at the same time, thereby increasing the pressure in the sealed cavity, and then making the medium temperature meet the requirements, and realizing constant temperature heating of the object to be tested; the designed plateau type pressure constant temperature water tank forms a sealed cavity through the inner tank and the sealed box cover, which is convenient for realizing accurate heating of the constant temperature water tank in the plateau environment, thereby improving the use effect of the constant temperature water tank.

[0012] By adopting the above technical solution, when the air pressure in the sealed chamber is greater than the sum of the elastic forces of multiple second springs, the air pressure generated in the sealed chamber applies force to the pressure relief plate, causing the volume of the sealed chamber to gradually increase, thereby reducing the pressure in the sealed chamber; the segmented design of the sealed box cover adjusts the volume of the sealed chamber by raising and lowering the pressure relief plate, thereby reducing the air pressure in the sealed chamber, thereby avoiding safety accidents in the constant temperature water tank caused by excessive air pressure in the sealed chamber.

[0013] Optionally, the pressure relief assembly includes a pressure relief pipe and a sealing plug cover;

[0017] By adopting the above technical solution, when the air pressure in the sealed chamber is too high and the air pressure in the sealed chamber is greater than the sum of the elastic forces of multiple second springs, the air pressure generated in the sealed chamber applies force to the pressure relief plate, causing the pressure relief plate to slide along the sliding chamber, resulting in the volume of the sealed chamber gradually increasing. When the pressure relief plate moves to the point where the inner cavity of the pressure relief pipe is connected to the inner cavity of the sealed chamber, the air pressure in the sealed chamber can be discharged through the pressure relief hole, thereby reducing the pressure in the sealed chamber. The designed pressure relief component can discharge the pressure by adjusting the volume of the sealed chamber and the opening and closing of the pressure relief hole, thereby achieving staged pressure relief of the sealed chamber and ensuring the safety performance of the plateau type pressure constant temperature water tank during use.

[0025] Optionally, a limit ring is provided on the outer periphery of the exhaust pipe, and the limit ring is located below the pressure relief plate.

[0026] By adopting the above technical solution, the designed limiting ring allows the pressure relief plate to move within a certain range, thereby limiting the pressure relief plate and preventing the pressure relief plate from separating from the exhaust pipe.

[0027] Optionally, it further includes a plurality of fixing components for fixing the inner container and the sealed box cover, wherein the fixing components include an upper connecting ear piece, a lower connecting ear piece, a gusset plate and a locking screw;

The buckle plate 63 is rotated, and the buckle plate 63 drives the locking screw 64 to rotate until the locking screw 64 is directly above the sealing box cover 4. Then, the turning handle 66 is turned, and the turning handle 66 drives the locking screw 64 to rotate. The locking screw 64 drives the abutment block 65 to move, so that the abutment block 65 moves toward the side of the sealing box cover 4 until the locking screw 64 is tightly against the top wall of the sealing box cover 4, thereby fixing the sealing box cover 4 and the inner liner 3.

[0063] After the processing is completed, adjust another first solenoid valve 85 and the first water pump 84 so that the medium in the sealed chamber 31 flows along the first liquid outlet pipe 83 to the liquid storage tank 81, and the medium flowing into the liquid storage tank 81 gradually cools down to prepare for reuse, adjust the controller 73, and the controller 73 sends an instruction to the electric heating tube 71, and the electric heater heats the medium in the sealed chamber 31 so that the temperature of the medium in the sealed chamber 31 increases, and the thermometer 72 continues to process the temperature of the medium in the sealed chamber 31. When the temperature of the medium reaches the use requirement, the thermometer 72 transmits a signal to the controller 73, and the controller 73 sends an instruction to stop the electric heating tube 71 from heating, and adjust another first solenoid valve 85 and the first water pump 84 so that the medium in the sealed chamber 31 flows along the first liquid outlet pipe 83 to the liquid storage tank 81, and the medium flowing into the liquid storage tank 81 gradually cools down to prepare for reuse.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
