To being the hydraulic element of medium with mineral oil, the definition of its ultrahigh pressure is meant pressure greater than 31.MPa, and sliding valve style ultrahigh pressure 3-position 4-way solenoid directional control valve in the market; Under ultrahigh-pressure hydraulic, clamping force is big, and switching-over is encountered difficulties; And the ball-valve type ultra-high pressure solenoid valve of foreign sales and sliding valve style are relatively, and under equal latus rectum flow, it is big that its pressure loss is wanted; And valve port suffers collision deformation after long-term the use, produces the malfunctioning and leakage phenomenon of switching-over.
Summary of the invention
The object of the invention is to above-mentioned situation, overcomes under high pressure the commutate problem of difficulty of slide-valve structure, provides a kind of switching-over reliably, is active in one's movements, and pressure can reach the ultrahigh pressure 3-position 4-way solenoid directional control valve of 70MPa.
The present invention includes valve body, in said valve body, axial hole is set, connect electromagnet respectively at the two ends of said through hole; Coaxial closely being nested with joined cunning cover in the said through hole between two blocks of electromagnet; Along said length direction of joining cunning cover, in said periphery of joining cunning cover the first annular undercut groove, the second annular undercut groove and the 3rd annular undercut groove are set, the said second annular undercut groove is arranged between the first annular undercut groove and the 3rd annular undercut groove; On the said second annular undercut groove, at least one pair of oil inlet hole is set, the center line of said every pair of oil inlet hole in same footpath upwards; At least one pair of first oil outlet is set on the said first annular undercut groove; The center line of said every pair first oil outlet in same footpath upwards; At least one pair of second oil outlet is set on the said the 3rd annular undercut groove, and the center line of said every pair second oil outlet in same footpath upwards; In said joining shaft-like spool is set in the cunning cover, the length direction of the said spool in edge is provided with two ring blocks that match with first oil outlet and second oil outlet respectively; In through hole, between said two ends of joining cunning cover and two blocks of electromagnet, one group of spring seat is set respectively; Said each spring seat is respectively equipped with an inner base frame and an outer seat; Said each inner base frame arranges that towards joining cunning cover said each outer seat is arranged towards electromagnet respectively, between every group of inner base frame and outer seat, connected spring respectively respectively; Between every group of inner base frame and outer seat, be provided with and the spring parallel push rod respectively; Said every push rod be separately positioned on join cunning cover axially on, an end of said every push rod is fixedly connected with corresponding inner base frame respectively, the other end is respectively towards electromagnet; The inner of said every push rod is provided with the outer termination touch of corresponding spool respectively, and the outer end of said every push rod is provided with corresponding electromagnet contact-type respectively.
When the present invention was cut off the power supply when the two ends electromagnet, spool mediated under the valve core spring power effect of two ends, and the ring block of spool makes each oilhole be in sealing state, and is not connected.When the left end electromagnet was switched on, the suction-combining force of electromagnet armature and magnetic core promoted spool and moves right, and every pair first oil outlet, second oil outlet are communicated with respectively; At this moment, left side spring is loosened, and the right spring is compacted; After the electromagnet outage; Lean on the effect of compressed the right Returnning spring, can make spool get back to the neutral position, recover original four oilholes situation of sealing mutually.When the right-hand member electromagnet was switched on, the suction-combining force of electromagnet armature and magnetic core promoted spool and is moved to the left, and every pair first oil outlet, second oil outlet are communicated with respectively; At this moment; The right spring is loosened, and left side spring is compacted, after the electromagnet outage; Lean on the effect of compressed left side Returnning spring, can make spool get back to the neutral position.
The present invention makes the bearing capacity of valve body higher owing to be provided with and join cunning cover, moves more stablely, and sealability is better.The present invention is simple in structure, and is easy to operate, overcomes under high pressure the commutate problem of difficulty of slide-valve structure, and switching-over is reliable, is active in one's movements, and pressure can reach 70MPa.
The present invention is provided with some annular wire casings respectively at each said ring block outer surface, is used to stockpile sludge, makes sealability better, and makes radial force more even.
