It is described for the ease of the operation principle to six-way valve, when six-way valve is described, connected applications are in air-conditioning
Situation in device is described, specific as follows：
When air conditioner freezes, the big electromagnetic coil 13 of main valve 1 is first given to be powered, the small electromagnetic coil 23 of pilot valve 2 is obstructed
Electricity, after big electromagnetic coil 13 is energized, generate magnetic force, repel each other between the magnetic force and permanent magnet 14 at this time, by main valve piston 12 to
The other end of main valve body 11 pushes, and is set at state i.e. the first operating position up to main valve piston 12 is in the right side, at this time pilot valve 2
Small electromagnetic coil 23 due to being not powered on, spring 25 is in relaxed state, and armature 24 is pushed away to the other end of guide valve blocks 21
It is dynamic, state i.e. third operating position is set to make guide's valve piston 22 be in a left side, then starts main compressor 5, through main compressor 5
The high-pressure refrigerant of generation enters by first pipe 41, third valve port 11c in the second valve chamber 12b of main valve 1, is then out master
Valve 1, and be divided into 34 two-way of third pipeline 43 and the 4th capillary, the high-pressure refrigerant through third pipeline 43 by condenser 6,
After expansion valve 7 and evaporator 8, low pressure refrigerant is changed into, after the 4th pipeline 44 and the 5th valve port 11e, flows back to the first of main valve 1
In valve chamber 12a, then returned in main compressor 5 through the first valve port 11a, second pipe 42.And pass through the height of the 4th capillary 34
Compression refrigerant, the 4th interface 24d through pilot valve 2 enters in pilot valve 2, into after pilot valve 2, through first in pilot valve 2
Channel 2a is using pilot valve 2 is flowed out after third channel 2c, the first interface 21a in the first fixed block 26, through the first capillary
31 enter main valve bodies 1 the 4th valve chamber 12d in, make to keep high pressure in the 4th valve chamber 12d, at this time in the 5th valve chamber 12e pressure compared with
It is low, it is acted on by high pressure, keeps the main valve piston 12 of main valve to be in the right side and set state.Meanwhile push main valve piston 12 to main valve
When the other end sliding of body 11, make in the 5th valve chamber 12e of main valve body 11 the lower refrigerant of pressure through third capillary 33, the
Three interface 21c are entered in pilot valve 2, after through the fourth lane 2d in the second fixed block 27, in guide's valve piston 22
Two channel 2b and second interface 21b flow out pilot valve 2, after enter through the second capillary 32 in first valve chamber 12a of main valve 1,
Then it is also returned in main compressor 5 through the first valve port 11a, second pipe 42.System operation for a period of time after, the big electricity of main valve 1
Magnetic coil 13 powers off, by position of the height control bound piston 12 of 12 both sides air pressure of main valve piston in main valve body 11.
