In the utility model, described connection plug screw main body is that an outer-hexagonal bolt arrangement is pieced together tightly with convenient shuttle valve is installed, simultaneously, lower body part has internal thread, and the mode that is threaded connection between the valve pocket is fixed, and cooperates the location by the positioning guide hole of internal thread notch and the location shoulder on valve pocket top.
In the utility model, described valve pocket axially on have two stage seal convexities, and be provided with the black box that is formed by O type circle and two-way back-up ring on sealing rank, two rank.
In the utility model, the maximum cylindrical of bottom end seal groove of valve pocket of valve seat of packing into is the radially minimum dimension of whole valve body, sealed groove maximum cylindrical in middle part takes second place, the radial dimension of upper end screw thread and location shoulder is maximum, and the entity size of every rear one-level all surmounts the boundary dimension after the previous stage Sealing is packed into to greatest extent.
The utility model adopts axial end to paste the mode of jail and screw threads for fastening aspect the installation location of valve, i.e. the maximum cylindrical of valve body place Design Orientation end face is finished axially locating in tight being threaded into to piece together.
Advantage of the present utility model and beneficial effect are:
1) polymorphic structure that, breaks away from original traditional shuttle valve from overall structure, adopt a kind of axial symmetrical rotary structure, be convenient to the production in enormous quantities of modern automatic numerical control equipment, traditional integrative-structure is separated, adopt general plug screw and general valve pocket to combine, reduced the quantity of different parts, be convenient to the modern optimization management, enhance productivity simultaneously, reduce manufacture cost.
2), select the aspect from Integration System Design, the position of laying this shuttle valve when the general jack of its compactness is convenient to the integrated package design.Revolution key element endoporus and cylindrical are adopted in the cooperation of valve and jack, in the modern comfort batch production, the processing of endoporus and cylindrical can obtain degree of precision and high conforming processing effect, after the jack standardization, the profile cutter of curable this jack of processing, be convenient to the production management of integrated package manufacturing firm, and general standard cutter can reduce cost greatly.
3), the project organization that adopts the valve pocket of multistage classification to carry out the classification sealing is convenient to the dismounting of valve, and the phenomenon that Sealing causes Sealing just to lose efficacy can not occur pulling in disassembly process in the process of installing.

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.
Schematic representation referring to the preferred embodiment of a kind of Novel threaded plug-in type split shuttle valve of Fig. 1-Fig. 3, in the present embodiment, be designed with on the plug screw 29 for screw thread piece together tight outer-hexagonal groove 1, step surface 28, the valve pocket of axially locating and sealing installed location shoulder 5, positioning guide hole 26, valve pocket 6 and is designed with for connecting P when being used for installing
2The P of mouth pressure oil
2Bore is to the bearing cavity 22 of runner 7, control steel ball 21, for connecting bearing cavity 22 and P
2Bore is to the internal thread groove 18 of the shaft orientation flowing channel 25 of runner 7, connecting valve seat 14 and the A bore of connecting bearing cavity 22 and A mouth to runner 10.
Plug screw O type circle 3 is by pack into valve body and shrinking in the groove of the step surface 28 of plug screw 29 of frock; Second level back-up ring 9 and second level O type circle 24 are packed into by frock in the valve pocket seal groove of the second level; First order O type circle 19 and first order back-up ring 12 are packed into by frock in the first order valve seal groove, in this two rank sealing configuration, the mounting point of O type circle and back-up ring as shown in the figure, the position arbitrarily can not be changed, in order to avoid under the actual conditions of valve, lose the function of back-up ring and to the too early damage of O type circle.
During installation, steel ball 21 is directly packed in the bearing cavity 22 of valve pocket 6; The centre of valve seat 14 has the logical oil hole 15 of interior hexagonal, is convenient to dismounting usefulness, and valve seat 14 leaves the surplus groove with the mounting interface position of valve pocket 6, and surplus groove O type circle 16 is housed within it.After the flank of thread of joint is coated screw thread glue, apply certain torsional moment with outer hexagonal spanner and screw by internal thread 18; Valve pocket 6 is coated with the after-applied certain torsional moment of screw thread glue and screws in plug screw 29, and location shoulder 5 and pilot hole 26 are finished the positioning and guiding of assembling in conjunction with screw thread.
Be designed with valve seat cone angle potted line 20 on the valve seat 14, guarantee that control steel ball 21 is taken a seat steadily and rapidly sealing; The upper end of carrying die cavity 22 and the relevant place of shaft orientation flowing channel 25 are designed with valve pocket cone angle potted line 23, guarantee that control steel ball 21 is taken a seat steadily and rapidly sealing; Distance between valve seat cone angle potted line 20 and the valve pocket cone angle potted line 23 determines the aperture of control steel ball 21 high pressure one end when commutation, and this determines that directly the logical pasta of valve amasss and carry out the speed of response of components and parts.Simultaneously, the size of the maximum cylindrical of each stage seal groove and plug screw connecting thread face becomes stepped and increases successively, and dismounting and the final assembly of being convenient to testing property after the whole valve assembling are used, and can not cause mechanical damage to all Sealings.
Pack into behind the jack such as Fig. 2, shown in Figure 3, work as P
1Mouth passes into control oil or P
1Mouth pressure is higher than P
2During mouth pressure, pressure oil promotes to move on the control steel ball 21 through the middle oil through 15 of valve seat 14, until control steel ball 21 contact valve pocket cone angle potted lines 23 pressure oils are full of whole bearing cavity 22, control steel ball 21 pressure oil and shaft orientation flowing channel 25 are separated this moment, and pressure oil flows to the A mouth through the A bore to runner 10 and finishes carrying out the operation of components and parts.
And on the other hand, work as P
2Mouth passes into control oil or P
2Mouth pressure is higher than P
1During mouth pressure, pressure oil is through P
2Bore moves down to runner 7 and shaft orientation flowing channel 25 promotion control steel balls 21, until control steel 21 contact valve seat cone angle potted lines 20 pressure oils are full of whole bearing cavity 22, control steel ball 21 pressure oil is separated by interior hexagonal oil through 15 this moment, and pressure oil flows to the A mouth through the A bore to runner 10 and finishes carrying out the operation of components and parts.
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 above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, 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.
