Spool 10 ' is placed in the space of lower cover and the formation of valve body lower portion 5 '.External control signal is input to the control of power device
Plate, driving motor work, motor drives gear train to rotate again, the output gear of power transmission to gear train；Output gear shaft
Cooperate with the spool 10 ' of volume control device, band movable valve plug 10 ' rotates, and spool 10 ' is internally provided with runner, passes through spool angle
The variation of degree, the switching of runner between Lai Shixian spool and valve body control the fluid media (medium) in new energy cooling system with this
The flow direction and flow in circuit.
Referring to Fig. 3, to ensure that fluid media (medium) does not leak, the first sealing ring is equipped between valve body lower portion 5 ' and spool 10 '
11 ', prevent fluid media (medium) from leaking into the power device installation space on top；The is equipped between bracket 7 ' and valve body lower portion 5 '
Two sealing rings 12 ' prevent fluid media (medium) from leaking into the external world.However, electronic valve is after being used for a long time, especially spool, valve body
Obvious to sealing surface galling, it is unreliable that sealing ring is possible to occur sealing after by galling, in valve body
Fluid media (medium) just will appear leakage phenomenon, so as to cause electronics defective valve.
Summary of the invention
The present invention is to solve above-mentioned technical problem of the existing technology, it is desirable to provide a kind of double containment of electronic valve
Structure.
In order to solve the above technical problems, the invention adopts the following technical scheme: a kind of double sealing structure of electronic valve, including
Valve body and spool, it is characterised in that by being integrally formed, be equipped between the valve body and spool prevents the valve body
Fluid media (medium) leaks into the first sealing ring and the second sealing ring of overhead power device installation space, first sealing ring and
Second sealing ring is arranged along poppet shaft to upper and lower interval.
Electronic valve is after being used for a long time, and especially spool, valve body are obvious to sealing surface galling, and sealing ring exists
Unreliable by being possible to occur sealing after galling, the intracorporal fluid media (medium) of valve just will appear leakage phenomenon, to lead
Send a telegraph sub- defective valve.After double sealing structure of the invention, the sealing effect of electronic valve can be greatly enhanced, is conducive to increase production
The reliability of product can simultaneously prolong the service life.Since the present invention uses integral valve body structure, thus in valve body top and valve body
Setting sealing ring is not needed between lower part, and the integral sealing effect of electronic valve is improved in the case where not increasing sealing ring quantity.
Yet another advantage of the present invention is that it is reasonable in design, the top of valve body and valve body lower portion are integrated in integrated die sinking
Molding, reduces the amount of parts of electronic valve product, and the technique for reducing valve body top and valve body lower portion assembly is reduced simultaneously

Valve body is integrally formed by mold, and the size of product can also be more easier to guarantee, while the weight of entire product can also reduce,
Lightweight, integrated target for main engine plants' requirement, it is easier to realize.
As an improvement of the present invention, the valve body includes valve body top, valve body necking part and valve body lower portion, and described
One sealing ring and the second sealing ring are arranged in the valve body necking part.
As a further improvement of the present invention, the spool includes core and valve rod, and stream is offered on the core
The intersection of road, the valve rod and core is equipped with step surface；First sealing ring and the second sealing ring are arranged described
At the cooperation of valve body necking part and valve rod.
As further improvement of the invention, the valve body necking part is equipped with bulge loop, the top plane of bulge loop, valve body contracting
The medial surface of neck and the lateral surface of valve rod constitute the first seal groove；The baseplane of bulge loop, the medial surface of valve body necking part, valve
The lateral surface of bar and the step surface of stem bottom constitute the second seal groove.
As further improvement of the invention, the medial surface of the valve body necking part and the lateral surface of valve rod are as sealing
Face forms with first sealing ring and the second sealing ring and is interference fitted.First sealing ring and the second sealing ring and its
The groove top plane and slot bottom plane clearance of corresponding seal groove cooperate.Since spool can be rotated, sealing ring and groove top plane and
Slot bottom plane clearance cooperates the abrasion that can reduce sealing ring, is conducive to extend the service life of sealing ring.
As further improvement of the invention, the valve body necking part is equipped with reinforcing rib, is not increasing valve body ruler
The intensity of valve body is greatly improved in the case where very little and wall thickness.
The structure and shape of the reinforcing rib are unlimited, and can reach enhancing purpose with it is advisable.Preferably, described plus
Strengthening tendons are radially arranged centered on the mandrel of spool, and quantity is advisable with 2 ~ 4, and multiple reinforcing ribs are in be uniformly arranged.
As a further improvement of the present invention, first sealing ring and the second sealing ring are O-ring or X shape ring.
