Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1,2,3, a kind of screw-in cartridge electromagnetic seat valve.Mainly by electromagnet 1, valve pocket 6, spool 7 threes, be effectively connected to form a two position three-way valve.
The outside thread 11 of valve pocket 6 guarantees to be connected with the effective of electromagnet internal thread, and outside thread 11 right-hand members are made a location shoulder, and this location shoulder is the assembling of being convenient to valve pocket 6 and electromagnet 1.On valve pocket 6, be provided with valve pocket main aperture 13, valve pocket main aperture 13 is axial ladder hole, and the left end outlet of valve pocket main aperture 13 is the first logical hydraulic fluid port 12; Valve pocket middle part is provided with the radially logical hydraulic fluid port 8 of the radially logical hydraulic fluid port 15, the second of the second radially logical hydraulic fluid port 8 and the 3rd communicating with valve pocket main aperture 13 and is positioned at the 3rd left side of logical hydraulic fluid port 15 radially.In valve pocket main aperture 13, be provided with the first oil sealing mouth 25 (being processed as of this first oil sealing mouth: make a chamfering at valve pocket main aperture 13, the second right-hand member ladder place that radially leads to hydraulic fluid port 8) for the radially logical hydraulic fluid port 15 of the second radially logical hydraulic fluid port 8 and the 3rd is cut off, the first oil sealing mouth 25 is horn mouth; The first logical hydraulic fluid port 12 places of valve pocket main aperture 13 arrange the valve seat 9 of multidiameter shaft shell-like, and the second oil sealing mouth 10, the second oil sealing mouths 10 that are provided with on valve seat 9 for the radially logical hydraulic fluid port 8 of the first logical hydraulic fluid port 12 and second is cut off are horn mouth.
Between the radially logical hydraulic fluid port 15 of the second radially logical hydraulic fluid port 8 and the 3rd, there is seal groove 24, the interior placement back-up ring of seal groove 24 and seal ring.Bilateral back-up ring can guarantee that seal ring is not in the course of the work because the impact force of both sides is destroyed seal ring, this group Sealing has not only stoped the communication of the fluid between the radially logical hydraulic fluid port 15 of the second radially logical hydraulic fluid port 8 and the 3rd, but also has stoped entering of dust.At the second left end that radially leads to hydraulic fluid port 8, make too a seal groove 26, in back-up ring and seal ring placement and groove.It is the closing in work of being convenient to the rear valve of valve pocket assembling that valve pocket left end is made a closing in face 27.The locating shoulder 28 of valve pocket left end coordinates with valve seat 9.
In the valve pocket main aperture 13 of valve pocket, be provided with spool 7, the left end of spool 7 is made first oil sealing surface 33 corresponding with the first oil sealing mouth 25 and second oil sealing surface 31 corresponding with the second oil sealing mouth 10; Between the first oil sealing mouth 25 and the first oil sealing surface 33, be conical surface linear sealing structure between the second oil sealing mouth 10 and the second oil sealing surface 31.Between the first oil sealing surface 33 and the second oil sealing surface 31, make convex shoulder 32, this convex shoulder 32 plays a part balance and guiding in spool moving process.Circular bead surface 34 on spool forms between Jian，Gai controlled oil region, a controlled oil region and is communicated with the 3rd radially logical hydraulic fluid port 15 with the main aperture of valve pocket, and the frustum at circular bead surface 34 right-hand member places is faced fluid and played leading role at flow process.On spool guide surface 37, make seal groove 36 and compensating groove 38, the interior placement seal ring 16 of seal groove 36, can prevent that fluid from leaking and preventing entering of dust.Compensating groove 38 can be stored the greasy dirt of spool in movement process, has also guaranteed the stationarity of valve core movement simultaneously.
On spool 7, be provided with the balance oil duct that connects two valve pockets that are divided into by spool and play the effect of balance oil pressure.This balance oil duct comprises along poppet shaft to making balance oil hole 35 and oil through 39, and spool is commutated reliably in movement process, makes electromagnet not affected by oil pressure.Spool right-hand member place locating slot 40 for placing Steel Cable Baffle Ring 3, spacing by Steel Cable Baffle Ring 3, can guarantee that packing ring 4 do not escape from spool, between spool and valve pocket main aperture 13, be provided with spring 5, this spring 5 is for drawing spring, spring 5 one end are positioned on packing ring 4, and the other end is positioned on the ladder surface of valve pocket main aperture.By spring force, spool is positioned, on the first oil sealing mouth 25 of valve pocket 6, to be now original function position, the second radially logical hydraulic fluid port 8 is positioned at the 3rd radially logical hydraulic fluid port 15 and is communicated with.
The push rod 2 of electromagnet withstands on spool 7.When electromagnet obtains electricly, push rod 2 promotes spools and moves right, until spool the second oil sealing surface 31 contact with the second oil sealing mouth 10 on valve seat, is now second function position, and the second radially logical hydraulic fluid port 8 is positioned at the 3rd and radially leads to hydraulic fluid port 15 communications.
Spool is under the effect of spring tension, end motion to the right, the first oil sealing surface 33 of spool and the first oil sealing mouth 25 tight closure on valve pocket, when hydraulic oil enters from the first logical hydraulic fluid port 12, fluid flows out from the second radially logical hydraulic fluid port 8, now fluid be full flow pass through and the 3rd radially logical hydraulic fluid port 15 obstructed.When electromagnet obtain electric after, the spring force that electromagnet push-rod 2 promotion spools 7 overcome spring 5 moves right, to the second oil sealing surface 31 of spool 7 and the second oil sealing mouth 10 closures of valve seat, now the second radially logical hydraulic fluid port 8 and the 3rd radially logical hydraulic fluid port 15 are communicated with, and the first logical 12 of hydraulic fluid ports pass through without any fluid.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
