DETAILED DESCRIPTION

[0018] As Figures 1 to 7As shown, a valve high and low temperature test device, including box 1, cloth warm plate 4 and cold and hot all-in-one machine 5. The bottom end of the box 1 is provided with cold and hot all-in-one machine 5, the back of the box 1 is provided with the outer machine matched with the cold and hot all-in-one machine 5. The back plate of the box 1 is provided with a plurality of fans 103.

[0019] The specific principle of the cold and hot all-in-one machine 5 can refer to air conditioner, and the generation of cold air and hot air is realized.

[0020] The box 1 is provided with a valve body 2 by a partition plate 3. Specifically, the two ends of the partition plate 3 are welded in the box 1. The upper surface and the lower surface of the partition plate 3 are attached with heat preservation plates. The partition plate 3 can play a certain heat insulation role, so that the electronic element part of the valve body 2 is free from the high and low temperature destruction of the test area.

[0021] The front end of the partition plate 3 is provided with a placing groove matched with the valve body 2, the placing groove is provided with a first semicircular groove 301, the placing groove is provided with a plug 303, and the plug 303 is provided with a second semicircular groove 302. The plug 303 is provided with a connecting hole 304, and the connecting hole 304 is provided with a connecting bolt matched with the partition plate 3.

[0022] In use, the valve body 2 needs to be placed into the first semicircular groove 301 of the partition plate 3, and then the plug 303 is inserted into the placing groove, so that the second semicircular groove 302 and the first semicircular groove 301 form a complete ring, and finally the connecting bolt is screwed into the connecting hole 304 to realize the detachable connection of the plug 303 and the partition plate 3. After the test is finished, the connecting bolt and the plug 303 are removed, and then the valve body 2 is taken out.

[0023] The lower part of the partition plate 3 is provided with the cloth warm plate 4 through the lifting mechanism 6; the cloth warm plate 4 is provided with cloth warm holes 403 and temperature sensors 405, and the cloth warm holes 403 are connected with the cold and hot all-in-one machine 5 through pipelines. The valve high and low temperature test device can truly detect the temperature of the test area in the box 1 by arranging the cloth warm holes 403 and the temperature sensors 405 on the up and down movable cloth warm plate 4, so that the temperature control in the box 1 is more accurate.

[0024] The upper surface and the lower surface of the cloth warm plate 4 are provided with temperature sensors 405 and cloth warm holes 403.

[0025] Specifically, the top end of the cold and hot all-in-one machine 5 is provided with a main exhaust pipe 501, and the left and right sides of the cold and hot all-in-one machine 5 are provided with air feeding mechanisms 502; a gas guide main pipe 503 is fixedly arranged in the box body 1, and the lower end of the gas guide main pipe 503 is connected with the air feeding mechanisms 502; a plurality of cloth-warming main holes 504 of different heights are uniformly arranged on the gas guide main pipe 503; a sliding hole 402 matched with the cloth-warming main hole 504 is arranged on the cloth-warming plate 4, and an adapter hole matched with the cloth-warming main hole 504 is arranged in the sliding hole 402; and a gas guide branch pipe 404 is arranged in the cloth-warming plate 4, and the gas guide branch pipe 404 is connected with the adapter hole and a cloth-warming branch hole 403.

[0026] The adapter hole in the sliding hole 402 of the cloth-warming plate 4 of the valve high and low temperature test device is matched with the cloth-warming main hole 504 on the gas guide main pipe 503, so that the cloth-warming branch hole 403 on the cloth-warming plate 4 can be connected with different cloth-warming main holes 504 at different heights, and cold air or hot air can be delivered to the middle area of the box body 1.

[0027] The cloth-warming main holes 504 of different heights on the gas guide main pipe 503 of the valve high and low temperature test device can play the role of matching with the cloth-warming plate 4 and the function of uniformly distributing cold air or hot air.

[0028] The hollow hole 406 matched with the valve body 2 is arranged on the cloth-warming plate 4, so that the cloth-warming plate 4 will not collide with the test part at the lower end of the valve body 2, and the cloth-warming plate 4 has a larger range of movement.

[0029] The lifting mechanism 6 comprises a lead screw 602 and a motor 601, the lead screw 602 is rotatably arranged in the box body 1, the motor 601 is fixedly arranged at the top end of the box body 1, the output end of the motor 601 is connected with the lead screw 602 after penetrating through the box body 1, and a threaded hole 401 matched with the lead screw 602 is arranged on the cloth-warming plate 4, and the threaded hole 401 is threadedly matched with the lead screw 602.

[0030] The lead screw 602 can also adopt two, and it is required to ensure that the two motors 601 are synchronous.

[0031] In order to ensure that the adapter hole in the sliding hole 402 of the cloth-warming plate 4 can be accurately matched with the cloth-warming main hole 504 on the gas guide main pipe 503, the motor 601 needs to adopt a servo motor.

[0032] The cold and hot all-in-one machine 5 is provided with a grating plate 102 which is fixed in the box 1 by a fixed clamp 101 welded on the side wall of the box 1, and the fixed clamp 101 does not contact with the lead screw 602 of the lifting mechanism 6. The grating plate 102 can prevent the valve body 2 from being accidentally dropped to hurt the cold and hot all-in-one machine 5.

[0033] The left side of the front end of the box 1 is hingedly provided with a door plate 7 by a hinge 701, and the door plate 7 is provided with an observation window 703 which is made of double-layer hollow heat-insulating glass. The right end of the door plate 7 is provided with a door lock 702 matched with the box 1, and the bottom end of the box 1 is provided with a foot wheel 104.

[0034] The working process of the present application is as follows: Firstly, the door lock 702 is opened to open the door plate 7 by the hinge 701, then the valve body 2 is fixed on the partition plate 3 by the plug 303 and the door plate 7 is closed, then the test temperature is set, the cold and hot all-in-one machine 5 starts to work, one part of the air flow reaches the test area through the grating plate 102 after passing through the main exhaust pipe 501, and the other part of the air flow reaches the test area through the cloth-warming main hole 504 after passing through the cloth-warming main pipe 503 by the air feeding mechanism 502; then the cloth-warming plate 4 at the lowermost end starts to move up and down, when the temperature sensor 405 detects that the temperature at a certain height does not reach the set temperature, the cloth-warming plate 4 stops at this height, and the cloth-warming branch hole 403 on the cloth-warming plate 4 guides the air flow from the cloth-warming main hole 504 to this place.

[0035] When the test is finished, the cloth-warming plate 4 needs to return to the lowermost end under the driving of the lifting mechanism 6, so as to avoid interfering with the removal of the valve body 2.

[0036] The above-described embodiments are only used to describe the preferred modes of the present application, and do not limit the scope of the present application, and various modifications and improvements of the technical solutions of the present application made by those skilled in the art without departing from the design spirit of the present application shall fall within the protection scope of the present application defined by the claims.
