As shown in Figure 1, among the figure general cartridge valve spool 20, the lower end has annular constriction in the spool, and shape is more irregular, processing technology complexity, processing cost height.
The model utility content
Technical problem to be solved in the utility model is, overcomes the problems that existing cartridge valve exists, and a kind of cover-plate type two-way plug-in valve is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of cover-plate type two-way plug-in valve, by a cartridge valve integrated package that has a spool, and the control cover plate that is arranged on the cartridge valve integrated package is formed, it is characterized in that, described spool is arranged on the cartridge valve integrated package by valve pocket, spool integral body is cylindrical, and the spool outside has annular groove, and the spool inboard has spring chamber; Described control cover plate inside has the control hydraulic circuit that communicates with the cartridge valve integrated package, and control cover plate one side also has the plug screw of a control oil pressure.
The spring chamber lower end has a through hole, and the through hole lower end has a flow controller.
The upper end of described valve pocket has the seal ring that twice have back-up ring, and the valve pocket lower end has the back-up ring that has seal ring together.
The surface of contact of described valve pocket top and control cover plate also is provided with packing ring.
Beneficial effect, the utility model are that screw plug in the pick-and-place components and valve pocket are combined, and two-way plug-in valve mainly is as directional control valve; Dispose simultaneously flow controller on its basis, two-way plug-in valve mainly is as relief valve.And flow controller has good responsiveness in order to adjust the response time of pick-and-place components, can realize the high-speed transitions of control valve, the valve body more reliable performance.This control mode is flexible, has played the dual-purpose good result of a valve, has realized economical structural design.Valve pocket and valve core structure are simple simultaneously, are convenient to processing, help improving total quality and reduce cost, and equally also are convenient to loading and unloading and maintenance.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is existing cartridge valve valve core structure schematic representation;
Fig. 2 is the cross-sectional view of a kind of cover-plate type two-way plug-in valve of the utility model;
Fig. 3 is the valve core structure schematic representation of a kind of cover-plate type two-way plug-in valve of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 2, Fig. 3, a kind of two-way plug-in valve of cover-plate type, it mainly is made up of control cover plate 1 and pick-and-place components 2.Control cover plate 1 is by outer control hydraulic circuit 3, pressure chamber hydraulic circuit 4, and control hydraulic circuit 5 is formed.By mach method pressure chamber hydraulic circuit 4 is connected at valve inner with control hydraulic circuit 5.Plug screw 6 is connected with outer control hydraulic circuit 3 with pressure chamber hydraulic circuit 4.Control the seal ring 7 that is provided with high pressure resistant high temperature on hydraulic circuit 3 and the screw plug 6 outside, strengthen its seal degree, the internal leak phenomenon is reduced, system pressure is stable.Hydraulic oil port adopts conical surface seal simultaneously, makes leakage little, and is also suitable for low viscous working mediums such as emulsified liquids, strengthened working life.
Plug-in unit 2 is by valve pocket 8, spool 9, and Returnning spring 10, screw plug 11 is adjusted pad 12 compositions such as grade.Process the appearance profile of valve pocket 8 by mach method, produce the internal oil passages of valve pocket 8 by the method for casting.Spool 9 is cylindrical, and the upper end has annular groove, and spool 9 will be convenient to processing than old spool 20, has simplified its structure, helps shortening process time, improves total quality and reduces cost.
Load onto high pressure resistant resistant to elevated temperatures seal ring 14 at the top of valve pocket 8, load onto back-up ring 13 in its outside then, be provided with in order to protect seal ring 14 to avoid destroying.Press them against between control cover plate 1 and the plug-in unit 2,, prevent that hydraulic oil from leaking and dust enters for control cover plate 1 and being connected of plug-in unit 2 are played the seal action that is even more important.
Make O shape ring recess in the centre of valve pocket 8 and place high pressure resistant resistant to elevated temperatures seal ring 16, and then cooperate back-up ring 15.Make O shape ring recess in the bottom of valve pocket 8 and place high pressure resistant high-temperature resistant seal ring 18, respectively cooperate a back-up ring 17 thereon down.These seal rings have been strengthened seal degree, and the internal leak phenomenon is reduced.
Pad 12 is adjusted in placement on valve pocket 8, and its effect is the axial clearance of adjusting between valve pocket 8 and the control cover plate 1.
Load onto screw plug 11 in the bottom of spool 9, two-way plug-in valve is as directional control valve; Dispose flow controller 19 on its basis, two-way plug-in valve is as relief valve.And flow controller has good responsiveness in order to adjust the response time of pick-and-place components, can realize the high-speed transitions of control valve, the valve body more reliable performance.Such fit system has played the dual-purpose good result of a valve, has realized economical structural design.
Spool 9 is fitted into valve pocket 8,, have influence on the stable state and the dynamic performance of valve at the Returnning spring 10 of the internal configurations of spool 9.So be equipped with the corresponding different cracking pressure of multiple spring rate.
During work: the opening direction that acts on valve of area A 1 and A2.Area A 3 and Returnning spring act on the valve closing direction.Synthetic useful direction (opening force or close power) has determined the on off state of two logical cartridge valves.
Supplied with by the outside from hydraulic fluid port B or control oil if act on the pilot pressure of area A 3, hydraulic fluid port A then closes.
Screw plug is loaded onto in the spool bottom, and two-way plug-in valve mainly is as directional control valve; When disposing flow controller on its basis and use together, two-way plug-in valve mainly is as relief valve.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; 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 changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
