Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Present pre-ferred embodiments are given below in conjunction with the accompanying drawings, to describe technical scheme in detail.
As shown in figure 1, the telescopic electromagnetic valve of the present invention includes inlet nipple 1, filter assemblies 2, residual shim 3, sleeve
4th, spring 5, core assembly 6, coil block 7, valve seat 8, in coil block 7, left end is provided with filter assemblies 2,1 He of inlet nipple
Between coil block 7 be threaded, threaded after inlet nipple 1 and coil block 7 by welding be relatively fixed, sleeve
4th, residual shim 3, spring 5, core assembly 6 are all located at right side in coil block 7, are provided with core assembly 6, valve element group in sleeve 4
Spring 5 is provided with part 6, residual shim 3 is fixed on top of the sleeve 4 near 5 side of spring, between valve seat 8 and coil block 7 is
Threaded, threaded after valve seat 8 and coil block 7 by welding be relatively fixed.
Fixed-Filter component 2, this connection while mechanical interface of other devices in circuit is connected of inlet nipple 1
Mode makes valve mechanism compact, and weight and volume reduces.
Residual shim 3 is prepared from by rustless steel, and its material is firmly corrosion-resistant, being capable of effective control core assembly and coil
Electromagnetic force between component, effectively can evade due to the core assembly absorption valve that causes of tension cannot close or close when
Between the long fault for causing.
Sleeve 4 is prepared from by rustless steel or magnetically soft alloy, is designed by Optimize magnetic circult, reasonable control sleeve wall thickness,
The structure can realize sleeve exchanging on the premise of valve magnetic circuit and response performance is not affected, and the difficulty of processing such as coil block
The spare part of big long the production cycle can extend active time, be easy to valve to be used repeatedly.
Spring 5 is made of stainless steel, necessary seal pressure during for providing valve closing, it is ensured that valve seal performance,
And ensure that valve is closed rapidly, cut off Propellant Supply in time.
Core assembly 6 is prepared from by fluoroplastics and accurate magnetically soft alloy Cr17NiTi press-fitting, and the structure is in magnetic Circuit Design
In play armature effect, realize valve energising when breakdown action, also act as the closing sealing function under valve off-position, from
And completely cut off propulsive medium circulation.
Coil block 7 is made up of the rustless steel of magnetically soft alloy and a separated magnetic effect, using welding manner molding, is meeting valve
On the premise of door intensity requirement, Optimize magnetic circult design, effective control lightweight packages, raising electromagnetic response performance is completed.
Valve seat 8 is prepared from by rustless steel, by controlling its Blade dimensions and spool stroke sealing pair, is provided enough close
Envelope is than pressure, it is ensured that under valve-closed state, propellant will not be leaked to pipe line downstream, by being spirally connected with coil block 7 and welding
Two ways, it is ensured that the centering of valve seat and prevent propellant to be leaked to surrounding.
The operation principle of the present invention is as follows：In coil block, left end is provided with filter assemblies, filter module can effectively every
