Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1-Fig. 3.
A kind of thread cartridge electromagnetism seat valve.Mainly effectively be connected to form a two position three-way valve through electromagnet 1 and valve pocket assembly.Be being connected of valve and valve piece to realize effectively connecting, guarantee through the seal arrangement of 3 groups of diverse locations that sealing does not have between each oil through and leak through the outside thread of valve pocket.In the electromagnet core end outside thread is set, realization is connected with the valve pocket internal thread, at the electromagnet core end one cylindrical hole is set, and this cylindrical cavity holds spool 6 right-hand member cylndrical surface and spring 4 and back-up ring 3.
The internal thread of valve pocket 5 guarantees and externally threaded effective connection of electromagnet, and the right side of valve pocket is the confined planes with the assembling of electromagnet 1.Axially make a main aperture along valve pocket, the main aperture two ends are provided with the shoulder hole respectively, and a location shoulder 22 is set on valve pocket right-hand member shoulder hole, and the locating shoulder right-hand member is a guide surface 21, is used for cooperating with seal ring 19, has guaranteed not leak through the fluid of balance hydraulic fluid port 35.The axial bore low order end is a tapped hole and bottom outlet thereof, has guaranteed to be connected with the effective of electromagnet.The secondary shoulder hole of main aperture left end cooperates with valve seat 11 and is spacing.Between valve seat fitting surface and main aperture, make oil sealing mouth 25, effectively the internal orifice oil sealing has guaranteed the useful area of oil sealing, and this oil sealing mouth cooperates with the first oil sealing mouth 33 on the spool 6, realizes the break-make of hydraulic fluid port through oil sealing or disconnection.
Valve pocket right-hand member outer installment one hex surface is used for the mounting or dismounting of valve, owing to this hex surface is and the valve pocket all-in-one-piece, so in pulling this face process, can directly the valve pocket assembly freely be come in and gone out in plug-in opening.The hex surface left end is made a spacing shoulder, and this shoulder has guaranteed the axial position between valve and the plug-in opening.The shoulder left end is made a Gewindefreistiche, not only is convenient to processing and can also be used to place seal ring 18, prevents that plug-in opening fluid from leaking and external dust gets into.The tool withdrawal groove left end is made connecting thread, and this screw thread and plug-in opening screw-thread fit are screwed, and it is fixed in the plug-in opening.Make sequence number 16 logical hydraulic fluid ports 3 on the screw thread left end shoulder cylndrical surface, make seal groove 24 on the cylinder shoulder of turning left, be used to place bilateral back-up ring 15 and seal ring 14, the sealing groove prevents string oil between hydraulic fluid port 2 and the hydraulic fluid port 3.Make shoulder at hydraulic fluid port 2 cylndrical surface left ends, seal groove 26 is set, be used to place bilateral back-up ring 9 and seal ring 10, the sealing groove prevents string oil between hydraulic fluid port 2 and the hydraulic fluid port 1.The back-up ring of each the seal ring both sides seal ring that adequately protected is not extruded destruction at work, has prolonged the working life of seal ring.Because it is little that this valve position is moved, so response is fast, so in design process in order to guarantee its speed of response, lead to hydraulic fluid port 2 and approach oil sealing surface 25 as much as possible.
The spool left end is made a conical surface---and the second oil sealing mouth 31, this oil sealing surface are to be used for cooperating with valve seat oil sealing mouth, make convex shoulder 32 at the right-hand member of the second oil sealing mouth 31, and this convex shoulder plays a part balance and guiding in the spool moving process.The transitional surface of convex shoulder right-hand member is to connect the convex shoulder 32 and the first oil sealing mouth 33; The first oil sealing mouth 33 be with valve pocket on oil sealing mouth 25 cooperate; Circular bead surface 34 on the spool forms a control oil interval with the main aperture of valve pocket; This interval and hydraulic fluid port 3 are linked up, and the frustum at circular bead surface 34 right-hand member places plays leading role in the face of fluid at flow process.On spool guide surface 37, make seal groove 36 and compensating groove 38; Place in the seal groove 36 at a distance from enclosing 17; This circle setting can effectively prevent string oil between hydraulic fluid port 1 and the hydraulic fluid port 3, can guarantee that not only oil sealing is reliable but also can make motion steadily, the power of in movement process, effectively reducing friction at a distance from enclosing 17.Being provided with of compensating groove can be stored the greasy dirt of spool in movement process, also guaranteed the stationarity of valve core movement simultaneously.Spool right-hand member cylndrical surface is to place spring, and spring one end contacts with valve seat locating shoulder 22, and the other end cooperates with back-up ring 3 in the locating slot 40.On the cylndrical surface, make an oil through 39 radially; Spool right-hand member place locating slot 40 be used to place back-up ring 3, spacing through back-up ring 3 can guarantee the mounting point of spring; This structure has guaranteed that spring is for drawing spring; Spool is positioned on the oil sealing mouth 25 of valve pocket 5 through spring force, is original function position this moment, hydraulic fluid port 1 is linked up with hydraulic fluid port 2.Link up with oil through 39 to making a ladder equilibrium oil mouth 35 along poppet shaft, hierarchic structure can guarantee that the processing of elongated orifices is simply effective.This oilhole can balance valve core the oil pressure in two chambeies up and down, it is reliable to make spool in movement process, not receive working pressure to influence switching-over.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
