Abstract

The utility model relates to a liquid storage tank, in particular to a liquid storage for refrigeration, which is provided with a liquid inlet, a liquid outlet and an air outlet. An air inlet end with the air outlet is positioned above the inner liquid level of the liquid storage tank, the liquid outlet is connected with an inlet of a condenser, the air outlet is connected with an inlet of a compressor, and an electromagnetic valve is arranged between the air outlet and the compressor. According to the technical scheme, one air outlet added to an original liquid storage tank structure is connected to the inlet of the compressor, the electromagnetic valve is used for control, and when pressure of return air of the compressor is insufficient, the electromagnetic valve is turned on, and air is exhausted from the air outlet and enters the compressor from the inlet to provide air return pressure for the compressor.

Description

Fluid reservoir

Technical field

The utility model relates to a kind of fluid reservoir, relates to a kind of cooling fluid reservoir specifically.

Background technology

In vapor-compression refrigerant cycle such as freezing and refrigeration, cryogenic refrigeration, fluid reservoir is one of refrigeration annex of using always.Traditional fluid reservoir simple structure; performance is single; only has the liquid storage function; in actual the use, because the common suction temperature of cryogenic refrigeration is lower, back pressure is not high; cause compressor can not bring into play efficient fully; influence refrigerating capacity, at this moment fluid reservoir can't make that the damageability of compressor is serious for the compressor Reduction of Students' Study Load under overload condition.

Summary of the invention

The purpose of this utility model provides a kind of fluid reservoir, and this fluid reservoir can also increase back pressure for compressor except having the liquid storage function.

For achieving the above object, the utility model has adopted following technical scheme: a kind of fluid reservoir, be provided with inlet and liquid outlet, also be provided with the gas outlet on the fluid reservoir, the inlet end of gas outlet is positioned on the inner liquid level of fluid reservoir, wherein liquid outlet links to each other with the import of condenser, and the gas outlet links to each other with the import of compressor, is provided with magnetic valve between gas outlet and the compressor.

Fluid reservoir of the present utility model is provided with and is first liquid-sighting glass and second liquid-sighting glass that vertical is arranged.

As shown from the above technical solution, the utility model is by setting up the import of a gas outlet company to compressor on the fluid reservoir original structure, control by magnetic valve, when the compressor return air insufficient pressure, magnetic valve is opened, gas is discharged by the gas outlet, enters the import of compressor, for compressor provides back pressure.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is use principle figure of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Fluid reservoir as shown in Figure 1 and Figure 2, be provided with inlet 11 and liquid outlet 12, also be provided with gas outlet 13 on the fluid reservoir 10, the inlet end of gas outlet 13 is positioned on the liquid level of fluid reservoir, wherein liquid outlet 12 links to each other with the import of condenser 20, gas outlet 13 links to each other with the import of compressor 30, is provided with magnetic valve 40 between gas outlet 13 and the compressor 30.Cold-producing medium is entered in the jar by inlet 11, is discharged by liquid outlet 12, and the liquid of discharge enters condenser 20 and cools off; When compressor 30 pressures of inspiration(Pi) were not enough, the magnetic valve 40 on 13 connecting leg roads, gas outlet was opened, and gas enters in the compressor, the back pressure of make up compressor 30, the operating efficiency of raising compressor 30.

As the more preferred scheme of the utility model, on fluid reservoir 10, be provided with and be first liquid-sighting glass 14 and second liquid-sighting glass 15 that vertical is arranged, the liquid level scope in the convenient observation jar and the humidity situation of cold-producing medium, when being lower than second liquid-sighting glass 15 as liquid level, fluid low in the fluid reservoir is described, needs to replenish cold-producing medium; When liquid level is higher than first liquid-sighting glass 14, illustrate that the liquid in the fluid reservoir is too much, be prone to liquid hammer in the tonifying Qi process; When liquid level is between first liquid-sighting glass 14 and second liquid-sighting glass 15, be safe range.

The course of work of the present utility model is as follows:

In conjunction with shown in Figure 3, cold-producing medium enters fluid reservoir 10 by inlet 11 again by compressor 30 condenser 20 of flowing through, and is discharged by liquid outlet 12 again, and the liquid of discharge flows to condenser once more and carried out coldly, carries out throttling through expansion valve 50 then, flows to evaporimeter then; When compressor 30 back pressures were not enough, magnetic valve 40 was opened, and the gas in the fluid reservoir 10 is entered in the compressor 30 by gas outlet 13, replenished return-air, increased back pressure.

The beneficial effects of the utility model are: 1) function is many, not only has the liquid storage function, also has the function that increases back pressure to compressor, and system is operated steadily reliably; 2) set up two liquid-sighting glass, can conveniently observe the liquid level in the fluid reservoir, thereby mechanism is controlled easily; 3) novel structure, the reliability height, manufacture craft is simple.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
