With reference to Fig. 2, described control enclosure 8 comprises the temperature be arranged on its housing face-plate and regulates display screen 81 and heating/cooling to change knob 82 and automatic/hand conversion knob 83.Described heating/cooling conversion knob 82 has heating, cooling two rotates position; Described automatic/hand conversion knob 83 has automatic, manual two and rotates position.
Fig. 3 is the two kind working state schematic representations of the hand valve of two-bit triplet described in the present invention 3 under described control enclosure 8 controls.
With reference to Fig. 3, two kinds of duties of described two-bit triplet hand valve 3 respectively: A mouth and the C mouth of valve core communicate, and B mouth and D mouth communicate (see Fig. 3 (a)); A mouth and the D mouth of valve core communicate, and B mouth and C mouth communicate (see Fig. 3 (b)).
Fig. 4 is the two kind working state schematic representations of the solenoid valve of two-bit triplet described in the present invention 4 under described control enclosure 8 controls.
With reference to Fig. 4, two kinds of duties of described two-bit triplet solenoid valve 4 respectively: A mouth and the C mouth of valve core communicate, and B mouth and D mouth communicate (see Fig. 4 (a)); A mouth and the D mouth of valve core communicate, and B mouth and C mouth communicate (see Fig. 4 (b)).
With reference to Fig. 1 composition graphs 2, the present invention is utilized to the course of work that described dish cabinet 01 cools to be: from the pressurized air of oil platform, filter through described filtering pressure reducing valve 1 and be adjusted to convenient pressure, be separated into cold through described eddy current refrigeratory 2 again, heat two strands of air-flows, thermal current wherein enters described two-bit triplet hand valve 3 and two-bit triplet solenoid valve 4 by hot gas outlet 21 and is discharged into home through safety dumping mouth 9, cold airflow is wherein by the variable valve 5 after described two-bit triplet hand valve 3 and two-bit triplet solenoid valve 4 described in arrival, the inside evenly spreading to described dish cabinet 01 by described ventilation terminal 7 again after the adjustment of described variable valve 5 cools to it, described vent port 011 is for getting rid of the hot-air accumulated in described dish cabinet 01.
In this course, the duty that the duty of described two-bit triplet hand valve 3 and two-bit triplet solenoid valve 4 is respectively the A mouth shown in Fig. 3 (a) He Fig. 4 (a) and C mouth communicates, B mouth and D mouth communicate, the valve core action forming this duty is controlled by the heating on described control enclosure 8/cooling conversion knob 82 and automatic/hand conversion knob 83, and the real time temperature in described dish cabinet 01 then regulates display screen 81 to be shown by the temperature on described control enclosure 8.
With reference to Fig. 2 composition graphs 3, Fig. 4, the method for operating that described heating/cooling conversion knob 82 and automatic/hand change knob 83 is:
Generally, described automatic/hand conversion knob 83 is in automatic position, the valve core of described two-bit triplet hand valve 3 is then in the state shown in Fig. 3 (a), so, only need the heating described in operation/cooling to change knob 82 and just can complete heating and cooling to described dish cabinet 01 by the valve core action of described two-bit triplet solenoid valve 4, that is:
When the heating described in rotating/cooling conversion knob 82 is to cooling position, the valve core of described two-bit triplet solenoid valve 4 is in the state shown in Fig. 4 (a), now, cold airflow from described eddy current refrigeratory 2 is transported in described dish cabinet 01, cool to the inside of described dish cabinet 01 and got rid of the hot-air accumulated described dish cabinet 01 inside by described vent port 011, the thermal current from described eddy current refrigeratory 2 is then discharged into home by safety dumping mouth 9;
Heating/cooling described in rotating changes knob 82 to when adding thermal potential, the valve core of described two-bit triplet solenoid valve 4 is in the state shown in Fig. 4 (b), now, thermal current from described eddy current refrigeratory 2 is transported in described dish cabinet 01, carry out intensification heating to the inside of described dish cabinet 01 and got rid of the humid air of described dish cabinet 01 inside by described vent port 011, the cold airflow from described eddy current refrigeratory 2 is then discharged into home by safety dumping mouth 9.
If described two-bit triplet solenoid valve 4 breaks down, then the described automatic/hand conversion knob 83 being originally in automatic position can be rotated to manual position, then, the two-bit triplet hand valve 3 described in manual operation and by the valve core action of described two-bit triplet hand valve 3 (as Fig. 3 (a) and Fig. 3 (b) is shown) realize to as described in the conversion of dish cabinet 01 heating and cooling duty.
The temperature transmitter 6 that described dish cabinet 01 inside is arranged is for the real time temperature measured in described dish cabinet 01 and temperature signal is sent to described control enclosure 8, regulate display screen 81 to show by the temperature on described control enclosure 8 again, described temperature regulates display screen 81 to be used for set temperature value.When described automatic/hand conversion knob 83 is positioned at automatic position, described control enclosure 8 can be automatically adjusted by the valve core aperture of temperature signal to described variable valve 5, thus by making the temperature of described dish cabinet 01 inside automatically regulate and be stabilized in the temperature value of setting to the automatic adjustment of gas flow thereupon; When described automatic/hand conversion knob 83 is positioned at manual position, the temperature adjustment display screen 81 on described control enclosure 8 can only show the real time temperature in described dish cabinet 01, can not carry out the automatic adjustment of temperature.
Above with reference to drawings and Examples, schematically describe technical scheme of the present invention, this description is not restricted.Those of ordinary skill in the art will be understood that in actual applications, and vibrational power flow of the present invention some likely occurs and changes, and other staff also may make similar Design under enlightenment of the present invention.Special needs to be pointed out is: only otherwise depart from design aim of the present invention, all apparent changes or similar Design, be all included within protection scope of the present invention.
