Abstract
The utility model relates to a two-position three-way hydraulic controlled valve for controlling fluid to pass through a pipeline and changing flow directions. The utility model comprises a valve body with two oil inlets and an oil outlet, a valve core and sealing rings, but the valve core is a smooth cylinder, and the sealing rings are arranged at both ends of the slip range of the valve core in the valve body. The oil outlet of the valve body is provided with hole channels which are respectively communicated with chambers of both ends of the valve core. The utility model has the advantages of compact and simple structure, rational oil channel, reliable performance, low friction coefficient, good seal with no leakage for the inner and the outer of the controlled valve, sanitation, cleanness and convenient use, is made into the controlled valve with a small size, and is particularly suitable for a braking system of a motor vehicle.
Description
The utility model relates to controlling liquid changes path direction by pipeline a kind of device.
Common two-position three way hydrovalve has manual control or electromagnetic control type, as disclosed technology in 92230572,95196298, controls spool for handle by connecting rod for one, and another is to move by the electromagnetic valve spool; Three-position electromagnetic selector valves etc. are led in disclosed hand reset two among the ZL91211216 in addition, except that control section, all the other structures are identical substantially, mainly by being provided with two filler openings, oil outlet or two oil outlets, filler openings and leaking the valve body of outlet, joint, the controlled spool that is slidingly matched with valve body, is connected with handle or electromagnet by connecting rod, Returnning spring and the O RunddichtringO that is contained in the valve body port place constitute, have oil groove or hole on the spool, the need that have in the valve body are established chamber in addition, and what have also need be provided with reset button and so on.The deficiencies in the prior art part mainly is: complex structure, and member is many, is unfavorable for miniaturization; Usability is not good enough, poor reliability, and internal and outernal leakage is serious, influence environmental hygiene; Applicable scope is restricted.
The purpose of this utility model is to avoid deficiency of the prior art, and a kind of simple structure is provided, and does not have to leak the two-position three way hydraulic control valve product that performance is good.
Can take following technological scheme to realize purpose.
The two-position three way hydraulic control valve, comprise the valve body that is provided with two filler openings, an oil outlet, the controlled spool and the seal ring that are slidingly matched with valve body, but spool is smooth cylindrical body, seal ring is installed in the place, two ends of valve body inner spool sliding scale, and the valve body oil outlet has the duct that is communicated with respectively with the chamber at spool two ends.
Satisfy under the prerequisite of said structure requirement, specific constructive form, size as for the integral body of two-position three way hydraulic control valve, each funtion part, each zero member, connection between member, means of fixation, position relation etc., all can be according to using needs, take the circumstances into consideration to set, they can both realize purpose, guarantee the usability and the effect of this hydraulic control valve.
The relative prior art of the technical program has following advantage and effect:
Simple structure, compactness, oil circuit is reasonable, can be made into the very little control valve of volume; Reliable performance, friction factor is low, good seal, inside and outside all do not have a leakage, and sanitation and hygiene are easy to use; Applicable scope is extensive, and the brake system that is particularly suitable for Motor Vehicle is used, and can realize that with it the front and back wheel while brakes or separately a certain the wheel braked with the identical power of holding tightly.
In conjunction with the accompanying drawings, mode of execution is described in further detail the content of the technical program.
Fig. 1,2 respectively is a kind of structural representation of two-position three way hydraulic control valve;
Fig. 3 is Fig. 1,2 plan view;
Fig. 4 is Fig. 1,2 side view;
Fig. 5 is a kind of structural representation of seal ring.
Embodiment 1, two-position three way hydraulic control valve, valve body 5 are provided with two filler openings of A, B, an oil outlet C, and each is communicated with A, B with the post chamber of spool one end; Spool 3 is the smooth cylindrical body that is slidingly matched with valve body, by the direct control action of pressure oil, need not other setting and applies external force; Seal ring 4 can adopt rectangle, Y shape or the identical seal ring of other performance, does not all have other groove, hole and so on valve body, the spool, obviously improves sealability, and seal ring is installed in the place, two ends of valve body inner spool sliding scale; Valve body oil outlet C has the duct that is communicated with respectively with the chamber at spool two ends, forms corresponding oil circuit.The valve A oil port is equipped with plug 7 and joins seal ring 6, and in addition end is stifled 1 with valve, to join seal ring 2 fixing.Shown in accompanying drawing 1,3,4.
As it being used for the motorcycle brake system, C connects the front brake pump, and A, B are connected with the oil outlet of the main and auxiliary oil pump of brake respectively.During the work of brake main oil pump, pressure oil one tunnel enters the back brake pump, trailing wheel is imposed braking moment; Another road enters the two-position three way hydraulic control valve from A, push away spool turn left block B mouth oil circuit, with its sealing, A is communicated with C, the brake main oil pump pressure oil enter the front brake pump, front-wheel imposed braking moment, the front and back brake pump is worked simultaneously, realizes the Associated brake of front and back wheel.When the work of brake auxiliary oil pump, pressure oil enters the two-position three way hydraulic control valve from B, push away spool turn right block A mouth oil circuit, with its sealing, B is communicated with auxiliary oil pump with C pressure oil enters the front brake pump, front-wheel is imposed braking moment, the front brake pump works independently, and realizes the front-wheel independent brake.Automatically control by pressure oil, need not facilities such as handle, connecting rod or electromagnet and impose external force.Other device that oil circuit is identical all can adopt.
Embodiment 2, two-position three way hydraulic control valve, seal ring 4 are y-type seal rings that central stuffing box gland is outstanding, there is radial direction oil hole 8 at the protruding terminus place; Other structure is all identical with embodiment 1.Shown in accompanying drawing 2,3,4,5, its usability, using effect are better.
Claims (2)
1, a kind of two-position three way hydraulic control valve, comprise the valve body that is provided with two filler openings, an oil outlet, the controlled spool and the seal ring that are slidingly matched with valve body, it is characterized in that: spool is smooth cylindrical body, seal ring is installed in the place, two ends of valve body inner spool sliding scale, and the valve body oil outlet has the duct that is communicated with respectively with the chamber at spool two ends.
2, two-position three way hydraulic control valve as claimed in claim 1 is characterized in that: seal ring is the y-type seal ring that central stuffing box gland is outstanding, there is radial direction oil hole at the protruding terminus place.
