Abstract
The utility model relates to a gas filling device for a temperature controller. The gas filling device comprises a drying oven and a vacuum pump, wherein a power element of the temperature controller is arranged in the drying oven, and the vacuum pump is connected with the drying oven. The gas filling device further comprises a replacement device, inside which an inert gas is arranged, wherein the replacement device is connected with the drying oven. The gas filling device for the temperature controller has the advantages that the inert gas is replaced in the drying oven which is subjected to vacuum drying, the condition that the drying oven cannot be subjected to chemical reaction with other gases in air is ensured, and the purity of filled gas of the drying oven is improved, so that the temperature stability of the temperature controller is improved, the temperature accuracy of the temperature controller is ensured to be controlled within +/-1.5, and the service effect is improved.
Description
Technical field
The utility model relates to temperature controller gas charge device.
Background technology
Temperature controller is integrated programming device and software and the switch of realizing intelligent control temperature; Can the free adjustment indoor temperature, and can set under switch and the various pattern that presets of various time periods automatically that operation regulates the room temperature by customer requirements, the temperature controller Core Feature is the control temperature; Improve topmost within the specific limits just right the filled gas purity of temperature control; As shown in Figure 1: as after existing technology is carried out vacuum drying to vacuum pump 2 through drying oven 1, but after drying is accomplished, not have the dried vacuum pump 2 of better protection, make airborne moisture or other gas get into the dry vacuum pump of crossing; Carrying out filling of cold-producing medium then; Making that to fill purity not high, cause the temperature controller control accuracy not high, the control accuracy of temperature controller generally can only be controlled at ± and 2.5.
The utility model content
The technical matters that the utility model will solve is that existing temperature controller gas charge causes the temperature controller control accuracy not high, thereby temperature controller gas charge device is provided.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: temperature controller gas charge device; Comprise drying oven, vacuum pump, be provided with temperature controller power spare in the said drying oven, said vacuum pump links to each other with drying oven; Comprise that also inside is provided with the displacement apparatus of inert gas, said displacement apparatus links to each other with drying oven.
Preferably, said inert gas is a nitrogen, also can be other inert gases, and the nitrogen chemical property is stable, and result of use is good.
In sum; The advantage of the utility model: replace inert gas in the propulsion system after vacuum drying; Guaranteed that propulsion system can not produce chemical reaction with airborne other gases, have improved propulsion system and have filled the purity of gas, thereby improved the temperature stability of temperature controller; The temperature accuracy that has guaranteed temperature controller is controlled at ± 1.5 in, improved result of use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of existing temperature controller gas charge device;
Fig. 2 is the structural representation of the utility model temperature controller gas charge device.
Embodiment
As shown in Figure 2, temperature controller gas charge device comprises drying oven 1, vacuum pump 2; Be provided with temperature controller power spare in the said drying oven 1, said vacuum pump 2 links to each other with drying oven 1, comprises that also inside is provided with the displacement apparatus 3 of inert gas; Said displacement apparatus 3 links to each other with drying oven 1, and said inert gas is a nitrogen, also can be other inert gases; The nitrogen chemical property is stable, and result of use is good.。
A: earlier the temperature controller power spare in the drying oven 1 is carried out vacuum drying through vacuum pump 2, the vacuum tightness in the drying oven 1 is set to-0.1MPa, and the true temp in the drying oven is controlled at the 103-107 degree;
B: then through replacing inert gas to dried drying oven 1 in the displacement apparatus 3;
C: carrying out cold-producing medium at last, filling temperature is 33 degree-37 degree, and filled pressure is 0.6MPa-0.7MPa.
Replace inert gas in the propulsion system after vacuum drying; Guaranteed that propulsion system can not produce chemical reaction with airborne other gases; Improved the purity of the filled gases of propulsion system; Thereby improved the temperature stability of temperature controller, guaranteed that the temperature accuracy of temperature controller is controlled at ± 1.5 in, improved result of use.
