Abstract
The utility model relates to a guiding valve formula structure, including being cylindric valve body, being located the steering control mechanism of valve body one side, be located cylindric fluid passage in the valve body, be located fluid passage's case, the case is cylindric sliding spool, seted up first hydraulic fluid port and second hydraulic fluid port on the valve body, and seted up the ring channel on the outer cylindrical surface of case, and the communicating inclined hole with fluid passage has been seted up in the first hydraulic fluid port. The utility model has the advantages of simple structure and reasonable design, it has the inclined hole to locate the design through the first hydraulic fluid port at the valve body, makes the liquid momentum that flows with the inflow ring channel cancel each other to reduce axial flow force, reduced stable state flow force, improve the working property of guiding valve.
Description
Technical field
The utility model relates to valve class field, relates in particular to a kind of slide-valve structure.
Background technology
Hydraulic valve is a kind of Automation Elements with pressure oil operation, and it is subject to distributing valve pressure oilControl, conventionally and electromagnetic distributing valve be used in combination, can be used for far distance controlled power station oil,The break-make of gas, water piping system. Oil circuits such as being usually used in clamping, controlling, be lubricated. Hydraulic valveBe divided into direction valve, flow valve, pressure valve etc. Hydraulic valve plays very heavy in hydraulic systemThe effect of wanting, any one hydraulic system, no matter how simple it is, all can not lack hydraulic pressureValve, the hydraulic machinery equipment of same technique object, by various combination and the use of hydraulic valve,Can form the distinct multiple hydraulic system scheme of oil channel structures, therefore hydraulic valve is hydraulic pressureMaximum, most widely used general, the most active elements of kind and specification in technology. The base of hydraulic valveThis structure mainly comprises the manipulation that spool, valve body and driving spool do relative motion in valve bodyControlling organization, the version of spool has multiple, offers the valve coordinating with spool on valve bodyBody opening or valve seat orifice, also have external oil pipe into and out of hydraulic fluid port, the operating mechanism of spool has handMode, mechanical type, electrodynamic type and hydrodynamic or electric hydrodynamic.
At present, guiding valve in use, under the fixing steady flow of valve port opening, liquidWhen stream flows through valve port, because momentum change produces a steady-state fluid force, steady-state fluid force not onlyStrengthen the needed power of manipulation guiding valve, and the service behaviour of guiding valve has been brought to adverse effect.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of side valve type knotStructure.
The utility model is to be achieved through the following technical solutions:
A kind of slide-valve structure, comprises cylindrical valve body, is positioned at described valve body one sideOperating control mechanism, be positioned at described valve body fluid passage cylindraceous, to be positioned at fluid logicalSpool in road, described spool is columned sliding spool, on described valve body, offers firstHydraulic fluid port and the second hydraulic fluid port, and offer cannelure on the outer cylinder surface of described spool, andIn described the first hydraulic fluid port, offer the inclined hole communicating with fluid passage.
As optimal technical scheme of the present utility model, described the first hydraulic fluid port is inlet, instituteStating the second hydraulic fluid port is liquid outlet, and the cross section of described the first hydraulic fluid port and the second hydraulic fluid port is circle.
As optimal technical scheme of the present utility model, the angle of described inclined hole and horizontal directionBe 30 degree-60 degree.
As optimal technical scheme of the present utility model, the diameter of described inclined hole is the first hydraulic fluid portThe half of diameter.
Compared with prior art, the beneficial effects of the utility model are: the utility model knotStructure is simple, reasonable in design, is designed with inclined hole by the first oil port at valve body, makes to flow outCancel each other with the liquid momentum that flows into cannelure, thereby reduce axial liquid power, reducedSteady-state fluid force, the service behaviour of raising guiding valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, withUnder by reference to the accompanying drawings and embodiment, the utility model is further elaborated. Should manageSeparate, specific embodiment described herein is only in order to explain the utility model, and is not used inLimit the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of slide-valve structure, comprises cylindrical valve body 1, is positioned at described valve body 1The operating control mechanism of one side, be positioned at described valve body 1 fluid passage cylindraceous 2,Be positioned at the spool 3 of fluid passage, described spool 3 is columned sliding spool, described valveOn body 1, offer the first hydraulic fluid port 4 and the second hydraulic fluid port 5, described the first hydraulic fluid port 4 is inlet,Described the second hydraulic fluid port 5 is liquid outlet, and the cross section of described the first hydraulic fluid port 4 and the second hydraulic fluid port 5Be circle.
On the outer cylinder surface of described spool 3, offer cannelure 6, and described firstIn hydraulic fluid port 4, offer the inclined hole 7 communicating with fluid passage 2, described inclined hole 7 and level sideTo angle be 30 degree-60 degree, the diameter of described inclined hole 7 is one of the first hydraulic fluid port 4 diametersHalf. Be designed with inclined hole by the first oil port at valve body, make to flow out and flow into cannelureLiquid momentum is cancelled each other, thereby reduces axial liquid power, has reduced steady-state fluid force, carriesThe service behaviour of high guiding valve.
Described valve body 1 adopts austenitic stainless steel to make, and anodization, energy are carried out in surfaceEffectively prevent corrosion, and austenitic stainless steel is carried out to the works such as chrome-faced, nickel, molybdenum, magnesiumSkill processing, also can improve the corrosion protection abrasion resistant performance of material.
Described spool 3 is taking metal as base material, and the composite taking pottery as top layer is made,Obdurability and ceramic high rigidity and the good wear-resistant corrosion resistance of metal were so both retainedCan, overcome again ceramic fragility.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this practicalityNovel, all any amendments of doing within spirit of the present utility model and principle, be equal to and replaceChange and improvement etc., within all should being included in protection domain of the present utility model.
