Abstract
The utility model discloses a tail sheet of a split type multi-path valve, which comprises a body, an oil port on the body, an upper gap bridge oil outlet, a lateral gap bridge oil outlet, a technical screw socket, a work piece mounting hole, an oil flow chamber communicated with the upper gap bridge oil outlet and the lateral gap bridge oil outlet, and an oil return chamber in the body, wherein the body is further provided with a technical lug boss which is provided with an internal open hole coaxial to the technical screw socket and communicated with the oil flow chamber; the oil port on the body, the upper gap bridge oil outlet, the lateral gap bridge oil outlet, the technical screw socket and the internal open hole can implement combination of various functions after being equipped with a choke plug or a backpressure valve so as to implement negative flow control function of a gap bridge or a hydraulic system; therefore, the tail sheet of the split type multi-path valve has excellent practical value and economic value.
Description
Technical field
The utility model relates to a kind of hydraulic multichannel valve member, particularly a kind of split type multi-way valve cauda.
Background technique
The multi-way valve compact structure is convenient to a plurality of work of centralized control actuator, therefore is widely used in the running mechanisms such as engineering machinery, handling machinery, mining machinery.Because these engineering vehicle hydraulic actuators are more; Comprise many group oil cylinders or motor; Often one group of multi-way valve can not satisfy the hydraulic system needs, needs two groups or more multi-way valve combination, and the oil circuit between these multi-way valve connects and must be serially connected sometimes; Be called gap bridge, realize the logic control between one group of multi-way valve of last group of multi-way valve and back.Common split type multi-way valve cauda only works the oil return effect that compiles, and perhaps as capping, oil circuit is blocked, not as the gap bridge effect.
Variable displacement pump uses on engineering machinery in a large number now, and through minus flow control, flow is big in the time of can having realized action, and flow is little during attonity.(so-called minus flow control, through in the multi-way valve outlet liquid resistance being set, the flow of the pump that the pressure difference before and after the liquid resistance is controlled if pressure reduction diminishes with regard to the flow that impels pump greatly, is kept a balance at last on small flow exactly.)
Two kinds of situation introducing above implement very difficulty for existing split type multi-way valve cauda structure, even realized, cost is also very high.
Summary of the invention
The technical problem that the utility model will solve provides a kind of split type multi-way valve cauda, realizes passing a bridge or hydraulic system minus flow control function.The technological scheme that it adopts is: a kind of split type multi-way valve cauda; Comprise body; Be positioned at hydraulic fluid port, top gap bridge oil outlet, side gap bridge oil outlet, technology screw socket, active gage mounting hole on the body, the logical oil pocket that is communicated with top gap bridge oil outlet and side gap bridge oil outlet, and be positioned at intrinsic oil back chamber; Also be provided with false boss in the wherein said body, and said false boss is provided with internal openings coaxial with the technology screw socket and that be communicated with logical oil pocket.
The beneficial effect of the utility model is: the utility model is in practical application; Be provided with on hydraulic fluid port on the said body, top gap bridge oil outlet, side gap bridge oil outlet, technology screw socket and the said false boss coaxial with the technology screw socket and and the internal openings that is communicated with of logical oil pocket; After being installed, plug or back pressure valve can realize multiple function combinations; Realize passing a bridge or hydraulic system minus flow control function, therefore have good use value and economic value.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Referring to figs. 1 through shown in Figure 4; A kind of split type multi-way valve cauda; Comprise body 1; Be positioned at hydraulic fluid port 2, top gap bridge oil outlet 3, side gap bridge oil outlet 4, technology screw socket 5, active gage mounting hole 6 on the body 1, the logical oil pocket 7 that is communicated with top gap bridge oil outlet 3 and side gap bridge oil outlet 4, and the oil back chamber 8 that is positioned at body 1; Also be provided with false boss 9 in the wherein said body 1, and said false boss 9 is provided with internal openings 10 coaxial with technology screw socket 5 and that be communicated with logical oil pocket 7.
The utility model is in practical application; Load onto plug respectively at hydraulic fluid port 2, top gap bridge oil outlet 3, internal openings 10 and technology screw socket 5, when system is in meta, behind the hydraulic oil process multi-way valve active gage by pump output; Get into the logical oil pocket 7 of cauda; The oil outlet 4 of passing a bridge from the side flows out, and gets into next group hydrovalve, realizes the gap bridge function; The side oil outlet 4 of passing a bridge is loaded onto plug, open top gap bridge oil outlet 3 plugs, realize from top gap bridge function.
Equally, the utility model is in practical application, if load onto plug at hydraulic fluid port 2, gap bridge oil outlet 3 is loaded onto the plug that has extraction oil-opening on top, loads onto the combined type back pressure valve at internal openings 10 and technology screw socket 5, and gap bridge oil outlet 4 is loaded onto plug in the side.When system is in meta, behind the hydraulic oil process multi-way valve active gage by pump output, get into the logical oil pocket 7 of cauda; Get into oil back chamber 6 through back pressure valve; Hydraulic oil produces pressure during through back pressure valve and falls the liquid resistance, with oil pipe the liquid resistance is fed back to variable displacement pump control port through the control oil drawing-off mouth that is contained on gap bridge oil outlet 3 plugs of top, realizes the control to pump duty; Promptly realize minus flow control function, the big I of feedback liquid resistance is regulated through the adjusting screw on the back pressure valve.
Can find out from above; The utility model is in practical application; Be provided with on hydraulic fluid port 2 on the said body 1, top gap bridge oil outlet 3, side gap bridge oil outlet 4, technology screw socket 5 and the said false boss 9 coaxial with the technology screw socket and and the internal openings 10 that is communicated with of logical oil pocket; After being installed, plug or back pressure valve can realize multiple function combinations, realize passing a bridge or hydraulic system minus flow control function therefore have good use value and economic value.
