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. 1
A stack valve body 03, about respectively make the plug-in mounting assembly and use the hole, this hole mainly is made up of seal groove 01, tapped hole 02, axial limiting groove 04 etc.Two inclined hole A1 are made in the upper end of stack valve body 03, B1 (05) communicates with axial limiting groove 04, and inclined hole 06 communicates with lower end straight hole A2, the B2 (07) of stack valve body 03.The lower end of stack valve body 03 is made seal groove 08 simultaneously, is used for the bottom surface sealing.
Plug-in mounting assembly 09 is respectively installed at the two ends, the left and right sides of stack valve body 03, is connected by tapped hole 02, prevents the fluid seepage by the seal ring 010 that is installed in the seal groove 01.
The bottom surface fitting tight circle 011 of stack valve body 03 prevents the fluid seepage.
Referring to Fig. 2-Fig. 5
The structure of plug-in mounting assembly is as follows:
A plug-in mounting assembly mainly is made up of plug-in mounting valve body 1, regulating handle 3, throttling valve core 4, orifice sleeve 5, pressure compensation spool 12, nonreturn valve core 13, big spring 8, little spring 14 etc.
The outer surface of plug-in mounting valve body 1 is made outside thread 18, is used for and stack being connected of valve body 03.Near outside thread 18, make seal groove 01, place seal ring 010, be used for sealing with stack valve body 03 joint.Stagger in its vicinity simultaneously and make each radial hole 10,11, be used for the circulation of fluid.Make big outer-hexagonal 28 at the left end of plug-in mounting valve body 1, when being used for the mounting or dismounting of stack valve body 03 and hexagon wrench be used.Make seal groove at its right-hand member outer surface, fitting tight circle 16 and back-up ring 17 are used for the sealing with stack valve body 03.
The left end cylindrical of adjustment sleeve 26 is made little outer-hexagonal 27, when being used for plug-in mounting valve body 1 mounting or dismounting and hexagon wrench be used.
Multistage cylindrical is arranged on the orifice sleeve 5 and make through hole, radially be provided with oval restriction 6.In the right-hand member through hole of orifice sleeve 5 is the unidirectional oil sealing surface 7 of nonreturn valve core 13.
The cylindrical right side of pressure compensation spool 12 cooperates with interior bone makes circular groove 9, is used for linking up with the runner of plug-in mounting valve body 1.
The right-hand member of regulating handle 3 make little in hexagonal blind hole 2, be used for when regulating flow and hexagon wrench is used.Inside at adjustment sleeve 26 processes seal groove, places seal ring 24 and back-up ring 25, prevents the internal leakage when rotating regulating handle 3 adjusting flows.Rotate regulating handle 3 and drive the size that throttling valve core 4 moves axially the restriction of regulating on the orifice sleeve 56, realize throttling.
A kind of overlapping Flow valve is that the throttle mechanism and the mechanism of decompressor are distributed by same axis, forms a plug-in mounting assembly 09 and refills in the stack valve body 03.Adorn two plug-in mounting assemblies 09 on the stack valve body 03, can realize hydraulic fluid port A1 and hydraulic fluid port B1 two chamber import speed governing.According to actual needs, also can about respectively adorn a plug-in mounting assembly 09 respectively, realize hydraulic fluid port A1 or hydraulic fluid port B1 or hydraulic fluid port P import speed governing.
Plug-in mounting assembly 09 is the hydraulic oil that flows from hydraulic fluid port A to hydraulic fluid port B, and 6 places are subjected to throttling action at restriction.Rotation regulating handle 3 can drive throttling valve core 4 and move axially, thereby plays the area of passage of throttling action, and throttling valve core 4 moves right, and restriction diminishes, and is moved to the left, and it is big that restriction becomes.
The effect of pressure compensation spool 12 is to keep constant flow, is not subjected to the influence that induced pressure changes and inlet pressure changes.Pressure compensation spool 12 is depressed into blind nut 15 by big spring 8, when not having flow to pass through, remains on the enable possition.As flow by the time, the pressure of A mouth acts on the pressure compensation spool 12, pressure compensation spool 12 is moved to the left, up to the equilibrium of forces of big spring 8 till.If the pressure of A mouth increases, pressure compensation spool 12 moves (openings get smaller between circular groove 9 and the radial hole 10,11) to closing direction, up to reaching equilibrium of forces once more.Because pressure compensation spool 12 continuous redeemings in through-flow process, under the constant situation of restriction 6, it is constant that the flow from hydraulic fluid port A to hydraulic fluid port B can keep.
If hydraulic oil flows from hydraulic fluid port B to hydraulic fluid port A, then the pressure of hydraulic fluid port B acts on the annulus area at unidirectional oil sealing surface 7 places, the power that promotion nonreturn valve core 13 overcomes little spring 14 moves right, unidirectional oil sealing surface 7 between orifice sleeve 5 and the nonreturn valve core 13 is opened, and liquid directly flows to hydraulic fluid port A through the straight hole of nonreturn valve core 13 inside without throttling.
Flowing to A2 (B2) from A1 (B1) in the overlapping Flow valve has the speed governing effect, flows to A1 (B1) from A2 (B2) and walks the one-way valve passage, does not have the speed governing effect.
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.
