Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1-Fig. 3.
A kind of thread cartridge Solenoid seated valve.Mainly effectively be connected to form a two position three-way valve by electromagnet 1 and valve pocket assembly.Be being connected of valve and valve piece to realize effectively connecting by the outside thread of valve pocket, guarantee that through the seal arrangement of 3 groups of diverse locations between each oil through, sealing is without leaking.In the electromagnet core end, outside thread is set, realizes and being connected of valve pocket internal thread, at the electromagnet core end, one cylindrical hole is set, 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, main aperture two ends arrange respectively the shoulder hole, on valve pocket right-hand member shoulder hole, a location shoulder 22 are set, and the locating shoulder right-hand member is a guide surface 21, is used for coordinating 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 coordinates with valve seat 11 and is spacing.Make oil sealing mouth 25 between valve seat fitting surface and main aperture, effectively the internal orifice oil sealing has guaranteed the useful area of oil sealing, and this oil sealing mouth coordinates with the first oil sealing mouth 33 on spool 6, realizes the break-make of hydraulic fluid port by oil sealing or disconnection.
Valve pocket right-hand member outer installment one hex surface is used for the mounting or dismounting of valve, because this hex surface is and the valve pocket all-in-one-piece, therefore can be directly that the valve pocket assembly is free in and out of plug-in opening in pulling this face process.The hex surface left end is made a spacing shoulder, and this shoulder has guaranteed the axial position between valve and plug-in opening.The shoulder left end is made a Gewindefreistiche, not only is convenient to processing and can also be used for placing seal ring 18, prevents that plug-in opening fluid from leaking and external dust enters.The tool withdrawal groove left end is made connecting thread, and this screw thread and plug-in opening screw-thread fit screw, and it is fixed in plug-in opening.Make the logical hydraulic fluid port 3 of sequence number 16 on screw thread left end shoulder cylndrical surface, make seal groove 24 on the cylinder shoulder of turning left, be used for placing bilateral back-up ring 15 and seal ring 14, the sealing groove prevents string oil between hydraulic fluid port 2 and hydraulic fluid port 3.Make shoulder at hydraulic fluid port 2 cylndrical surface left ends, seal groove 26 is set, be used for placing bilateral back-up ring 9 and seal ring 10, the sealing groove prevents string oil between hydraulic fluid port 2 and hydraulic fluid port 1.The back-up ring of each seal ring both sides seal ring that adequately protected is not extruded destruction at work, has extended the working life of seal ring.Due to this valve position move little, therefore response is fast, thus in design process in order to guarantee its speed of response, logical hydraulic fluid port 2 is as much as possible close to oil sealing surface 25.
The spool left end is made a conical surface---and the second oil sealing mouth 31, this oil sealing surface are for coordinating 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 convex shoulder 32 and the first oil sealing mouth 33, the first oil sealing mouth 33 is to coordinate with oil sealing mouth 25 on valve pocket, circular bead surface 34 on spool and the main aperture of valve pocket form between a controlled oil region, this interval and hydraulic fluid port 3 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.Make seal groove 36 and compensating groove 38 on spool guide surface 37, the interior placement of seal groove 36 is every enclosing 17, this circle setting can effectively prevent string oil between hydraulic fluid port 1 and hydraulic fluid port 3, can guarantee that not only oil sealing is reliable but also can make motion steadily, the power of effectively reducing friction in movement process every enclosing 17.Arranging of compensating groove can be stored the greasy dirt of spool in movement process, also guaranteed simultaneously the stationarity of valve core movement.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 coordinates with back-up ring 3 in locating slot 40.Make an oil through 39 radially on the cylndrical surface, spool right-hand member place locating slot 40 for placing back-up ring 3, spacing by back-up ring 3, can guarantee the mounting point of spring, this structure has guaranteed that spring is for drawing spring, by spring force, spool is positioned on the oil sealing mouth 25 of valve pocket 5, is original function position, hydraulic fluid port 1 and hydraulic fluid port 2 communications this moment.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, make spool not be subjected to working pressure to affect commutation in movement process reliable.
Above demonstration 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; that describes in above-described embodiment and specification just illustrates 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 the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
