Embodiment
Referring to Fig. 1～Figure 12, for the mortor operated valve of refrigeration system, comprise valve seat 41, motor 42 and valve gap 43; On described valve seat 41, be provided with an entrance 411, pressure relief opening 412 and an a plurality of outlet 413, described pressure relief opening 412 and outlet 413 are positioned on the upper surface of valve seat 41; Described valve gap 43 is sheathed on the top of described valve seat 41; Described motor 42 is fixedly installed on described valve gap 43, and described motor 42 comprises stator 421 and rotor 422, and described stator 421 is arranged on the outer surface of described valve gap 43, and described rotor 422 is arranged among the inner chamber of described valve gap 43; The center portion of described rotor 422 is provided with axle 4221 and described rotor 422 can be around the center line rotation of axle 4221; The lower end of described axle 4221 is fixed with the spool 44 that offers pressure-relief flow guide groove 441 and groove 442, and the upper surface of the lower surface of described spool 44 and described valve seat 41 connects, described pressure-relief flow guide groove 441 is opened on the lower surface of described spool 44, and described groove 442 penetrates described spool 44 along the thickness direction of described spool 44.
On the motor stator of mortor operated valve, be also provided with external power supply interface 11, the motor that is mortor operated valve by external power supply is powered.Described motor is stepper motor.When spool 44 rotates, described mortor operated valve 4 can change between cut-off state, open mode and pressure release state.
Cut-off state is: all not connected between any one outlet 413 of the pressure-relief flow guide groove 441 of described spool 44 and groove 442 and described valve seat 41, pressure relief opening 412 and outlet 413 are all blocked by spool 44, between entrance 411 and arbitrary outlet 413 or pressure relief opening 412, all do not communicate.
Open mode: the groove 442 of spool 44 be just positioned at outlet 413 directly over and pressure relief opening 412 by spool 44, blocked, the groove 442 of described spool 44 communicates with the outlet 413 of described valve seat 41, the groove 442 of described entrance 411 by spool 44 is connected with outlet 413, and pressure relief opening 412 with export 413 and entrance 411 between all do not communicate.
Pressure release state: the pressure-relief flow guide groove 441 of spool 44 is just positioned at top and the groove 442 of outlet 413 and pressure relief opening 412 and is blocked by valve seat 41, between the pressure-relief flow guide groove 441 of spool 44 and the outlet 413 of described valve seat and pressure relief opening 412, be all connected, because pressure-relief flow guide groove 441 is positioned on the lower surface of spool 44 and does not penetrate described spool 44, therefore pressure-relief flow guide groove 441 be only from inside just pressure relief opening 412 and outlet 413 be connected, thereby described entrance 411 does not all communicate with arbitrary outlet 413, pressure relief opening 412.
Refrigeration system comprises compressor, one-way valve, condenser, mortor operated valve, capillary tube and vaporizer; Described compressor, one-way valve, condenser, mortor operated valve, capillary tube and vaporizer are connected successively, and one end of described vaporizer is connected with capillary tube, and the other end of vaporizer is connected with compressor, form a cycle refrigeration system.The pressure relief opening of the valve seat of described mortor operated valve is connected between compressor and one-way valve by relief tube, and when mortor operated valve is during in pressure release state, exhaust outlet of compressor is flowed to low pressure evaporator to a small amount of pressurized gas in one-way valve.
