For the ease of being described the operation principle of six-way valve, when being described six-way valve, connected applications situation in air-conditioner is described, specific as follows:
nullWhen air-conditioner freezes，It is energized first to the big solenoid 13 of main valve 1，Little solenoid 23 no power of pilot valve 2，After big solenoid 13 is energized，Produce magnetic force，Now repel each other between this magnetic force and permanent magnet 14，Main valve piston 12 is promoted to the other end of main valve body 11，Until main valve piston 12 is at right configuration state that is first operating position，Now the little solenoid 23 of pilot valve 2 is owing to being not powered on，Spring 25 is in relaxed state，Armature 24 is promoted to the other end of guide valve blocks 21，So that pilot valve piston 22 is in left configuration state that is the 3rd operating position，Then main compressor 5 is started，Through main compressor 5 produce high-pressure refrigerant through the first pipeline 41、3rd valve port 11c enters in the second valve pocket 12b of main valve 1，It is then out main valve 1，And it is divided into the 3rd pipeline 43 and the 4th capillary tube 34 two-way，Through the high-pressure refrigerant of the 3rd pipeline 43 through condenser 6、After expansion valve 7 and vaporizer 8，Change into low pressure refrigerant，After the 4th pipeline 44 and the 5th valve port 11e，Flow back in the first valve pocket 12a of main valve 1，Then through the first valve port 11a、Second pipe 42 returns in main compressor 5.And through the high-pressure refrigerant of the 4th capillary tube 34, enter in pilot valve 2 through the 4th interface 24d of pilot valve 2, after entering pilot valve 2, after the third channel 2c in the first fixed block 26, first interface 21a, pilot valve 2 is flowed out again through the first passage 2a in pilot valve 2, in the first capillary tube 31 enters the 4th valve pocket 12d of main valve body 1, making to keep in the 4th valve pocket 12d high pressure, now in the 5th valve pocket 12e, pressure is relatively low, by high pressure effect, the main valve piston 12 of main valve is kept to be in right configuration state.Simultaneously, when promoting main valve piston 12 to slide to the other end of main valve body 11, the cold-producing medium making pressure in the 5th valve pocket 12e of main valve body 11 relatively low enters in pilot valve 2 through three capillary the 33, the 3rd interface 21c, after fourth lane 2d in the second fixed block 27, the second channel 2b in pilot valve piston 22 and the second interface 21b flow out pilot valve 2, after in the second capillary tube 32 enters the first valve pocket 12a of main valve 1, the most also return in main compressor 5 through the first valve port 11a, second pipe 42.After system runs a period of time, big solenoid 13 power-off of main valve 1, the height control bound piston 12 of dependence main valve piston 12 both sides air pressure position in main valve body 11.
nullWhen air-conditioner freezes，It is energized to little solenoid 23，Produce magnetic force，Attracting with armature 24，Pilot valve piston 22 is driven to slide to the direction of the one end near guide valve blocks 21，Until pilot valve piston 22 is in the state that the right side is put，I.e. the 4th operating position，During this，Spring 25 is compressed，Now，Big solenoid 13 is received and the most contrary signal of telecommunication，And produce attracting power between permanent magnet 14，Thus drive main valve piston 12 to slide to the one end of main valve body 11，Until main valve piston 12 is in left configuration state，I.e. second operating position，During this，Main compressor 5 is in out-of-work state，Then，Start standby electric compressor 9，High-pressure refrigerant through producing for electric compressor 9 is through the 5th pipeline 45、4th valve port 11d enters in the 3rd valve pocket 12c of main valve 1，Then main valve 1 is flowed out through the 6th valve port 11f，And it is divided into the 3rd pipeline 43 and the 4th capillary tube 34 two-way，Through the high-pressure refrigerant of the 3rd pipeline 43 through condenser 6、After expansion valve 7 and vaporizer 8，Change into low pressure refrigerant，Through the 4th pipeline 44 and the 5th valve port 11e，Flow back in the second valve pocket 12b of main valve 1，Then through the second valve port 11b、6th pipeline 46 returns in standby electric compressor 9.And through the high-pressure refrigerant of the 4th capillary tube 34, enter in pilot valve 2 through the 4th interface 24d of pilot valve 2, after entering pilot valve 2, after fourth lane 2d in the second fixed block 27, the 3rd interface 21c, pilot valve 2 is flowed out again through the first passage 2a in pilot valve 2, the 5th valve pocket 12e of main valve body 1 is entered through three capillary 33, the 5th valve pocket 12e is made to keep high pressure, now the pressure in the 4th valve pocket 12d is relatively low, by high pressure effect, the main valve piston 12 of main valve 1 is kept to be in the state that a left side is put.Simultaneously, when promoting main valve piston 12 to slide to one end of main valve body 11, the cold-producing medium making pressure in the 4th valve pocket 12d of main valve body 11 relatively low enters in pilot valve 2 through the first capillary tube 31, first interface 21a, after the third channel 2c in the first fixed block 26, the second channel 2b in pilot valve piston 22 and the second interface 21b flow out pilot valve 2, after in the second capillary tube 32 enters the second valve pocket 12b of main valve 1, the most also in the second valve port 11b, the 6th pipeline 46 return to standby electric compressor 9.After system runs a period of time, big solenoid 13 power-off of main valve 1, the height control bound piston 12 of dependence main valve piston 12 both sides air pressure position in main valve body 11.
In sum, the six-way valve simple in construction of the present invention, apply in the refrigeration system of air-conditioner, the cost of refrigeration system, main valve and pilot valve can be greatly saved and only play interim effect with the use of, the big solenoid of main valve, thus work efficiency can be improved.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
