Description
Technical field
The utility model relates to a kind of novel pressure-retaining system, relates in particular to a kind of pressure-retaining system of ice cream maker.
Background technology
At present, in ice cream maker is made, be to replace reciprocating compressor mostly, in the hope of reaching the purpose that reduces production costs with rotary compressor.It is not enough and be unsuitable for the problems of frequent starting that but existing rotary compressor has a refrigerating capacity.As everyone knows, because the precondition that rotary compressor starts is to want the suction and discharge pressure at two ends will be near balance, and when the ice cream maker frequent starting, rotary compressor suction and discharge pressure at two ends is difficult near balance, therefore can't normally start, can not reach the requirement of refrigeration, and also easily rotary compressor be caused damage reduction of service life.And, the characteristics of icecream production require will in time freeze when going out ice-cream product exactly, usually shorten the pressure release time by reducing the pressure release amount, and existing ice cream maker is when quitting work, the pressure release amount is big, the pressure transient equilibrium at the two ends of compressor suction and discharge can not be made, thereby the needs that start at any time can not be satisfied.
Therefore, need to occur a kind ofly high frequent being started and refrigerating capacity abundance, the fast ice cream maker of refrigerating speed.
The utility model content
The purpose of this utility model provides and a kind ofly high frequent started and the pressure-retaining system of the ice cream maker that refrigerating capacity abundance, refrigerating speed are fast.
For achieving the above object, the utility model proposes a kind of pressure-retaining system of ice cream maker, comprise by rotary compressor, condenser, filter, capillary, evaporimeter is connected successively by efferent duct and return duct the closed-loop path of formation is set, on the efferent duct of described rotary compressor both sides and return duct, be provided with second return duct, first end of described second return duct and described rotary compressor are connected with described efferent duct between the described condenser, its second end and described rotary compressor are connected with described return duct between the described evaporimeter, on described second return duct, be provided with first magnetic valve, on first end of described second return duct and the described efferent duct between the described condenser, be provided with first check valve.
Wherein, on second end of described second return duct and the described return duct between the described evaporimeter, be provided with second check valve.
Wherein, between described filter and described capillary, be provided with second magnetic valve.
Wherein, be communicated with by threeway between first end of described second return duct and the described efferent duct.
Because the utility model adopts technique scheme, therefore have following beneficial effect:
1, refrigerating speed is fast;
2, being suitable for high frequent starts.
Description of drawings

Fig. 2 is that duty condensed gas of the present utility model flows to schematic diagram.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-rotary compressor; The 2-efferent duct; The 3-return duct; The 4-threeway; 5-first check valve; The 6-condenser; The 7-filter; 8-second magnetic valve; The 9-capillary; The 10-evaporimeter; 11-second check valve; 12-first magnetic valve; 13-second return duct; 14-first end; 15-second end.
The specific embodiment
Please refer to Fig. 1 and Fig. 2, be respectively structural representation of the present utility model and duty condensed gas of the present utility model flows to schematic diagram.As shown in the figure, the pressure-retaining system of the utility model ice cream maker, comprising is connected by efferent duct 2 and return duct 3 successively by rotary compressor 1, condenser 6, filter 7, capillary 9, evaporimeter 10 is provided with the closed-loop path that forms, and makes condensed gas to circulate in this closed-loop path.On the efferent duct 2 of described rotary compressor 1 both sides and return duct 3, be provided with second return duct 13, first end 14 of described second return duct 13 and described rotary compressor 1 are connected with described efferent duct 2 between the described condenser 6, second end 15 of described second return duct 13 and described rotary compressor 1 are connected with described return duct 3 between the described evaporimeter 10, make the high pressure condensed gas can be back to the input end that refluxes by the output of rotary compressor 1.On described second return duct 13, be provided with first magnetic valve 12, make 13 conductings of second return duct or sealing by controlling first magnetic valve 12.On first end 14 of described second return duct 13 and the described efferent duct 2 between the described condenser 6, be provided with first check valve 5, thus the conducting or the sealing of control efferent duct 2.
Further, on second end 15 of described second return duct 13 and the return duct 3 between the described evaporimeter 10, be provided with second check valve 11, thus the conducting or the sealing of control return duct 3.
Further, between described filter 7 and described capillary 9, be provided with second magnetic valve 8.When closing second magnetic valve 8, can stop condensed gas by flowing out in the condenser, thereby keep the condenser internal pressure.
Further, described first check valve 5, second check valve 11 and second magnetic valve 8 are by sensor control synchro switch.
In addition, be connected by threeway 4 between first end 14 of described second return duct 13 and the described efferent duct 2.
Operation principle of the present utility model is, when start, first check valve 5, second magnetic valve 8, second check valve 11 are opened, and first magnetic valve 12 cuts out.Shown in arrow among Fig. 2, gases at high pressure lead to condenser 6, filter 7, capillary 9 and evaporimeter 10 respectively by first check valve 5, and by becoming low-pressure gas after the gases at high pressure acting, last low-pressure gas is back in the compressor 1 by second check valve 11, so periodic duty realizes refrigeration.When shutdown, first check valve 5 is closed, second magnetic valve 8 cuts out under the signal controlling of sensor, and second check valve 11 is also closed under the effect that pressure changes, and first magnetic valve 12 is open-minded, and at this moment the gases at high pressure that flow out from compressor 1 directly are back in the compressor 1 by second loop pipe 13 and first magnetic valve 12.Wherein, first check valve 5 can stop gases at high pressure to flow to condenser 6, forces gases at high pressure to be back to compressor 1.Second magnetic valve 8 receives the signal instruction of sensor and cuts out simultaneously when doing in the compressor shut-down, play the effect that keeps condenser 6 internal pressures, simultaneously having guaranteed that also compressor institute work stores, is to recover refrigeration rapidly at needs, has accelerated refrigerating speed.Close second check valve 11, prevent overheated gas Returning evaporimeter 6, make prefabricated ice cream keep freezing state.The utility model is by being provided with second loop pipe 13 and first magnetic valve 12, and the limit fluid direction reduces the pressure release amount like this, makes to keep compressor air suction, pressure at expulsion balance, satisfies the needs that high frequent starts.The advantage that has refrigerating speed simultaneously.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
