Specific embodiment：
In order to be better understood from and implement, giving embodiment below in conjunction with the accompanying drawings, the present invention will be described in detail；Illustrated embodiment is only
For explaining the present invention, it is not intended to limit protection scope of the present invention.
Embodiment 1 referring to Fig. 1,2,3,4,6,7,11, according to the design needs, is processed into valve body 1, upper cover 2,3 and of lower cover
Spool 4；By spool 4 inside valve body 1, tetra- channels of A.B.C.D are all provided with around valve body 1, are referred to as take over 8,4 one longitudinal direction of spool
Section is I-shaped structure of lifting one's head up and down, and upper shaft 12 and the spool of spool 4 can be integrated or splits；
4 lateral cross section of spool is ellipsoidal structure, and oval major diameter is at 24 position of spool interval；Alternatively, since oval spool makes work
Skill is comparatively laborious, so when processing circle can also be made, but 24 part of spool interval is expanded in spool 4, i.e., in spool
It is more than the diameter of two shoulder of spool, 23 position every 24 position diameters, the leakage rate of four-way valve can be greatly reduced in this way；In spool 4
It is embedded on two shoulder 23 of spool embedded with copper sheathing or other rub resistance sealing materials 7；There is interstitial hole in upper cover 2, shaft is from upper on spool 4
2 interstitial hole of lid is drawn, and there are two O-rings 10 for dress between 2 interstitial hole of shaft and upper cover on spool 4, and the upper hole of upper cover 2 is cone
Hole, inside are compressed equipped with matched hard sealing material 16 by clamp nut 17；By shaft on spool 4 and drive component 6
Output shaft is attached, and motor 14 is installed on drive component 6；6 outside installation upper cap 5 of drive component, upper cap 5 is mounted on upper
On lid 2, it is sealed by sealing element 21；The power cord that motor 14 is drawn, 15 phase of terminal connections plate with 5 upper end of upper cap
Even, terminal connections plate 15 is connect with external control system；Lower cover 3 is installed in 1 lower end of valve body, the two is tightly connected；On spool 4
4 times output shaft positions of output shaft position and spool, equipped with bearing 9,9 outer ring of bearing connects upper and lower covers center respectively；By valve body 1,
Upper cover 2 and 3 three's closed group of lower cover a kind of electric four-way valve into of the invention.
Embodiment 2, referring to Fig. 4, copper sheathing or other rub resistance sealing of the present embodiment also on two shoulder 23 of the spool of spool 4
It drilling on material 7, hole depth is more than the thickness of copper sheathing or other rub resistance sealing materials 7, and lubrication sealing material 13 is housed in hole,
Most preferably graphite rod；Groove is provided in 24 part of spool interval simultaneously, graphite either copper material or other antifrictions are embedded in groove
Sealing material, most preferably graphite bar 22 are wiped, so as to make spool 4 in the rotation, is unlikely to stuck by impurity.
Embodiment 3, referring to Fig. 8, the present embodiment also has hole in 4 lower surface of spool, positioning pin 11 is installed in hole, in lower cover 3
Upper surface is provided with the positioning ring groove 25 with fan angle, and positioning ring groove 25 is 90 ° in Fig. 8, and positioning pin 11 is in positioning ring groove 25
It is mobile.
Embodiment 4, referring to Fig. 8,9, the present embodiment also installs magnetic patch 18 in 4 bottom end of spool；Sensing is also provided on lower cover 3
Device hole 20, gauge hole 20 are through-hole or blind hole, and sensor 19 is filled in gauge hole 20.
Embodiment 5, referring to Fig. 9, the present embodiment employs shield electric machine, 14 internal rotor of motor, 29 outside installation housing
30,31 part of coil of motor 14 is external, in order to overhaul；It can also be driven with magnetic coupling.
Embodiment 6, referring to Figure 10, the present embodiment also installs visor 33 in 4 bottom of spool, and position instruction is carried on spool 4
32, so as to pass through visor 33, it can be seen that the rotation situation of spool 4；The connection of take over 8 uses the side of pipe connecting flange 34 simultaneously
Formula, so as to make pipeline connection more convenient.
A kind of electric four-way valve of the present invention, when normal work, after external control system makes motor 14 be powered,
Drive component 6 is driven to rotate, 6 output shaft of drive component band movable valve plug 4 rotates, and positioning pin 11 also follows spool 4 to rotate, due to fixed
Position pin 11 is in positioning ring groove 25, so when spool 4 turns to scheduled annular groove angle, then spool 4 just stops operating, at this time valve
19 position of sensor is gone to the rotation of spool 4 with magnetic patch 18, magnetic patch 18 on core 4, sensor 19 exports to be believed in place
Number, control system makes motor 14 have a power failure, so as to complete first switching action；
When another state is needed, control system makes the energization reversion of motor 14, and band movable valve plug 4 also inverts, when spool 4
Positioning pin 11 is driven to go to another the preset position of positioning ring groove 25 simultaneously, the magnetic patch 18 that 4 lower surface of spool is equipped with also turns
To the position of another sensor 19, sensor 19 exports signal in place makes electricity to external control system, external control system
Machine 14 has a power failure, so as to complete the switching of second state.
Referring to Fig. 5,6, normal conditions lower channel A, B are high-pressure channels, and C, D are low-pressure channel, and which results in spools 4 to work
When, it is amesiality, since spool needs to rotate, so 4 diameter of spool is less than 1 diameter of bore of valve body, at this time if spool 4
For circle, then fluid leaks into low-pressure side by gap 26, results in many energy expenditures；And if spool 4 is oval structure,
Then 26 position of leakage-gap will become very little, so as to greatly reduced the internal leakage of valve.
