Abstract
The invention discloses a micro-cooling capacity exchange device, which comprises a refrigeration source, a test-piece box, a main pipeline and a circulation pipeline; cooling water flows out from the refrigeration source, passes through the main pipeline and the circulation pipeline in sequence, and finally enters the test-piece box; the circulation pipeline is used for feeding the cooling water discharged from the test-piece box into the test-piece box in a circulatory manner; the main pipeline is connected with the circulation pipeline through electromagnetic valves; the main pipeline is used for feeding fresh cooling water into the cooling water circulating in the circulation pipeline through three electromagnetic valves; a water pump for feeding the cooling water into the test-piece box is arranged on the circulation pipeline; and a backflow pipeline is also arranged between the test-piece box and the refrigeration source. By means of the manner, the micro-cooling capacity exchange device is provided; the temperature in the test-piece box is adjusted by using the cooling water in different circulating manners; the precise adjustment of micro-cooling capacity can be realized; furthermore, a relatively large amount of energy can be saved by adopting the circulating manner; and the purposes of protecting the environment and saving the energy are achieved.
Description
Technical field
The present invention relates to field of experiment equipment, particularly relate to a kind of chilly amount switch.
Background technology
chilly amount switch is one of chief component in a series of temperature control experiment equipment such as frozen process experiment machine, and it is mainly used in carrying out trace to temperature and regulates, to reach the object that temperature accurately controls.Chilly amount switch uses cooling water to carry out temperature control usually, and the size controlling discharge regulates temperature, but due to the backflow of the water yield and the problem of conveying capacity, likely causes drainage improper.When recirculated water can not be got rid of in time, will cause thermoregulator out of control, for experimental data, there is considerable influence.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of chilly amount switch, and it is reasonable in design, and structure is simple, solves the inharmonious and problem of temperature control that causes of water yield turnover amount.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is to provide a kind of chilly amount switch, comprises refrigeration source, test piece box, main pipeline and circulating line; Cooling water flows out from refrigeration source and finally enters described test piece box through main pipeline, circulating line successively; Test piece box is sent in the cooling water recirculation that described test piece box is discharged by described circulating line; Described main pipeline is connected with described circulating line by magnetic valve; Fresh cooling water to be sent in the cooling water circulated in described circulating line by described main pipeline by three magnetic valves; Described circulating line is provided with water pump and send cooling water in described test piece box; Also reflux line is provided with between described test piece box and described refrigeration source.
Preferably, described three magnetic valves comprise the first magnetic valve, the second magnetic valve and the 3rd magnetic valve; Described first magnetic valve is positioned on the main fluid path of described main pipeline; Described main pipeline and the respective side walls of circulating line are provided with the discharge orifice being connected described second magnetic valve, the 3rd magnetic valve.
The invention has the beneficial effects as follows: a kind of chilly amount switch is provided, the temperature in chilled water modulation test piece box is made by different endless form, can not realize the fine adjustment of chilly amount, and this endless form can save the more energy, realize the object of environmental protection and energy saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of chilly amount switch of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, refrigeration source; 2, main pipeline; 3, circulating line; 4, test piece box; 5, water pump; 6, reflux line; 7, the first magnetic valve; 8, the second magnetic valve; 9, the 3rd magnetic valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to accompanying drawing 1, the embodiment of the present invention comprises:
A kind of chilly amount switch, comprises refrigeration source 1, main pipeline 2, circulating line 3 and test piece box 4; Cooling water flows out from refrigeration source 1 and finally enters described test piece box 4 through main pipeline 2, circulating line 3 successively; Test piece box 4 is sent in the cooling water recirculation that test piece box 4 is discharged by described circulating line 3; Described circulating line 3 is connected with described refrigeration source 1 by magnetic valve by described main pipeline 2; Fresh cooling water is sent in the cooling water of circulation in described circulating line 3 by three magnetic valves by described main pipeline 2; Described circulating line 3 is provided with water pump 5 and send cooling water in described test piece box 4; Reflux line 6 is also provided with between described test piece box 4 and described refrigeration source 1.Described three magnetic valves comprise the first magnetic valve 7, second magnetic valve 8 and the 3rd magnetic valve 9; Described first magnetic valve 8 is positioned on the main fluid path of described main pipeline 2; Described main pipeline 2 and the respective side walls of circulating line 3 are provided with the discharge orifice being connected described second magnetic valve 8, the 3rd magnetic valve 9.After cooling water flows out from refrigeration source 1, can be undertaken delivering into circulating line 3 by main pipeline 2, circulating line 3 has water pump 5 to provide direct driving force to be entered by cooling water circulation in test piece box 4, second magnetic valve 8 and the 3rd magnetic valve 9 are then the cooling water of main pipeline 2 is carried out shunting enter circulating line 3, effectively can prevent the temperature leak caused because of Cemented filling.Cooling water is carried out partial circulating repeatedly by circulating line, and the reflux line between test piece box and refrigeration source is then responsible for systemic circulation, and the mode adopting two circulations to superpose like this reaches the effect that temperature accurately controls.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
