In order to solve the above technical problems, it is an object of the invention to provide a kind of mining electromagnetic pilot valve core, solving impression
Problem of non-uniform, increases service life.
A kind of mining electromagnetic pilot valve core of the present invention, including plug, return spring, feed liquor seal, side push rod, valve
Seat, valve element guide pin bushing, time liquid-tight sealing, push rod, force transducer and joint, the plug offer cavity, and return spring is placed in sky
In chamber；Return spring connects feed liquor seal, and feed liquor seal is placed in the cavity of plug；Plug connecting valve seat；The valve seat
Connection valve element guide pin bushing, is provided with back liquid-tight sealing in valve element guide pin bushing；The push rod insertion Integral joint first half and time liquid-tight envelope
Part is contacted；The valve element guide pin bushing is integrally connected formula joint；Force transducer is provided with Integral joint；Locating rod penetrability inserts valve
Core guide pin bushing, two ends are inserted in valve seat and Integral joint respectively.
Further, the side push rod is inserted in the connecting valve seat first half.
Further, the Integral joint includes packing ring and joint, and packing ring is fixedly connected joint and is integrally formed.
Further, the push rod other end grows Integral joint and is contacted with force transducer.
Further, it is arranged with saddle on the side push rod and push rod.
By such scheme, the present invention at least has advantages below：In order to solve Problems Existing, the present invention acts on push rod
In the active force of liquid-tight sealing is returned compared with center-biased certain distance, the generation of moment of torsion can be avoided by this kind of improvement, realize pressure
Trace it is uniform, significantly improve the physical life of pilot valve；In order to realize that this kind of structure reduces processing and assembly precision, will be existing
Have packing ring has carried out integrated design with joint, is changed into Integral joint；Locating rod in order to ensure assembling when position it is accurate
Property, sealing surface impression problem of non-uniform is can effectively solve the problem that, pilot valve service life can be significantly improved.
Described above is only the general introduction of technical solution of the present invention, in order to better understand technological means of the invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Brief description of the drawings
Fig. 1 is the structural representation of mining electromagnetic pilot valve core.
In figure：Plug 1, return spring 2, feed liquor seal 3, side push rod 4, valve seat 5, valve element guide pin bushing 6, return liquid-tight sealing 7,
Push rod 8, force transducer 9, Integral joint 10, locating rod 11.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the invention is described in further detail, is below implemented
Example is not limited to the scope of the present invention for illustrating the present invention.
Referring to Fig. 1, operation principle of the invention is as follows：A kind of mining electromagnetic pilot valve core, including plug 1, return bullet
Spring 2, feed liquor seal 3, side push rod 4, valve seat 5, valve element guide pin bushing 6, time liquid-tight sealing 7, push rod 8, force transducer 9 and joint, institute
State plug 1 and offer cavity, return spring 2 is placed in cavity；The connection feed liquor of return spring 2 seal 3, feed liquor seal 3 is put
In in the cavity of plug 1；The connecting valve seat 5 of plug 1；The connection valve element of the valve seat 5 guide pin bushing 6, liquid-tight envelope is provided with back in valve element guide pin bushing 6
Part 7；The push rod 8 inserts the first half of Integral joint 10 and is contacted with liquid-tight sealing 7 is returned；The valve element guide pin bushing 6 is integrally connected formula
Joint 10；Force transducer 9 is provided with Integral joint 10；The penetrability of locating rod 11 insertion valve element guide pin bushing 6, valve is inserted at two ends respectively
In seat 5 and Integral joint 10.
Side push rod 4 is inserted in the first half of connecting valve seat 5.Integral joint 10 includes packing ring and joint, and packing ring is fixedly connected
Joint is integrally formed.The other end of push rod 8 grows Integral joint 10 and is contacted with force transducer 9.Covered on side push rod 4 and push rod 8
It is provided with saddle.
Feed liquor seal 3 is pressed close to valve seat 5 and realizes sealing by return spring 2 and hydraulic coupling collective effect；Work as force transducer
11 by after external force, promoting push rod 8 to move, and push rod 8 and then promotes back liquid-tight sealing 7 to move to be sealed until being adjacent to the realization of valve seat 5.When
After being adjacent to, return liquid-tight sealing 7 and be subject to the force value F1 that push rod 8 acts on center, the hydraulic coupling F2, the counter-force of valve seat 5 that act on center
