Inside be provided with the switching chamber moved for valve rod, be provided with in described valve body switching chamber and the extraneous first passage of UNICOM, second
Passage and third channel, described first passage is provided with switching connection position, chamber and seals the first sealing coordinated with sealing member
Mouthful, described second channel is provided with sealing member with switching connection position, chamber and seals the second seal coordinated, and described first is close
Sealing and the second seal are positioned on the motion track of sealing member and lay respectively at the both sides of sealing member, described Electromagnetic Drive machine
During structure energising, electromagnetic drive mechanism drives valve rod to move to electromagnetic drive mechanism, and sealing member and the second seal support joins and seals；
During described electromagnetic drive mechanism power-off, valve rod is automatically reset by electromagnetic drive mechanism to valve body, and sealing member and the first seal support
Join and seal.
By using technique scheme, set up pipeline, and the first seal and the second seal are positioned at sealing member
On motion track and lay respectively at the both sides of sealing member, there is when valve rod stretches various states, three pipelines can be joined simultaneously
Logical, or two of which pipeline is carried out UNICOM, and also electromagnetic drive mechanism loses magnetic force when power is off, enables pipeline automatic
Switching.
This utility model is further arranged to: described electromagnetic drive mechanism includes passing and guide leading of valve rod for valve rod
Set, is provided with the back-moving spring resetted by valve rod to valve body in described guide pin bushing, described guide pin bushing outer peripheral face set arranges suction valve
The electric magnet that bar moves.
By using technique scheme, electric magnet attracts valve rod away from valve body when energising, and back-moving spring is when power is off
Valve rod is resetted to valve body, thus realizes the function of automatic switching-over pipeline.
This utility model is further arranged to: described valve rod is installed the end of sealing member and is coaxially arranged with mounting disc, institute
The sealing member stated is coated on the elastic layer of this mounting disc.
By using technique scheme, on the one hand mounting disc revenge elastic layer makes sealing member have bigger contact surface,
On the other hand increase and convenience and mounting stability are installed.
This utility model is further arranged to: the first described seal and the second seal are towards the end of sealing member
Cross section semicircular in shape is arranged.
By using technique scheme, the abutting end of cross section semicircular in shape makes the end face of the first seal stretch into sealing member
In, increase sealing member deformation, strengthen sealing property.
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of this utility model detailed description of the invention.
Fig. 2 is the structure sectional view of this utility model detailed description of the invention.
Detailed description of the invention
As shown in Fig. 1 Fig. 2, the utility model discloses a kind of automatic diverter valve, including valve body 1, valve rod 2, sealing member 3
And electromagnetic drive mechanism 4, electromagnetic drive mechanism 4 drives valve rod 2 axially retractable, another of the relative electromagnetic drive mechanism 4 of valve rod 2
End is positioned at valve body 1 and for installing sealing member 3, is provided with runner in valve body 1, it is characterised in that: it is provided with in valve body 1 for valve
The switching chamber that bar 2 moves, is provided with switching chamber and the extraneous first passage 11 of UNICOM, second channel 12 and threeway in valve body 1
Road 13, first passage 11 is provided with switching connection position, chamber and seals the first seal 111 coordinated, second channel with sealing member 3
12 are provided with sealing member 3 with switching connection position, chamber seals the second seal 121 coordinated, and the first seal 111 and second seals
Mouth 121 is positioned on the motion track of sealing member 3 and lays respectively at the both sides of sealing member 3, when electromagnetic drive mechanism 4 is energized, electromagnetism
Drive mechanism 4 drives valve rod 2 to move to electromagnetic drive mechanism 4, and sealing member 3 supports with the second seal 121 joins and seals；Electromagnetism drives
During motivation structure 4 power-off, valve rod 2 is automatically reset by electromagnetic drive mechanism 4 to valve body 1, and sealing member 3 and the first seal 111 support and join also
