Wherein, preferably three kinds of schemes, that is:
The first scheme: described slide rail center is connected with plate washer, described slide rail two ends are respectively arranged with the through hole being communicated with filler opening and the first adjustable head piece, filler opening and the second adjustable head piece.
First scheme: described its length is greater than slide rail length.
The third scheme: described slide rail center is connected with plate washer, described slide rail is evenly provided with several circular holes that is identical, that can be communicated with filler opening and the first adjustable head piece, filler opening and the second adjustable head piece.
Above-mentioned three kinds of schemes all can change the size of the first adjustable head piece and the second adjustable head piece by moving slider, and then change the different proportion of shunting, comprise equivalent shunting, wherein, the first scheme and the third scheme directly can estimate scale, more convenient.
The beneficial effects of the utility model are: the different proportion that can regulate shunting according to actual needs, and structure is simple, and cost is low, easy to operate, can meet more industrial requirements.

The mark implication of accompanying drawing is as follows:
1: filler opening; 2: the first oil outlets; 3: the second oil outlets; 4: the first adjustable head pieces; 5: the second adjustable head pieces; 6: valve body; 7: spool; 8: the first springs; 9: the second springs; 10: the first intercommunicating pores; 11: the second intercommunicating pores; 12: the first spring cavity volumes; 13: the second spring cavity volumes; 14: slide rail; 15: slide block; 16: plate washer; 17: graduation line.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of piston type shunt valve being convenient to regulate, comprises valve body 6, described valve body 6 is provided with filler opening 1, first oil outlet 2 and the second oil outlet 3, be provided with spool 7 between described filler opening 1, first oil outlet 2 and the second oil outlet 3.Traditional structure, bottom filler opening 1, arrange two fixed throttle ports, its size determines the ratio of shunting, is uncontrollable, uses more inconvenient.
And the utility model, described spool 7 is provided with the plate washer 16 corresponding with filler opening 1, and the direction of arrow that namely plate washer 16 direction is corresponding with 1 is parallel, filler opening 1 is divided into two entrances.Described plate washer 16 be provided with slide rail 14 and along the slide block 15 of slide rail 14 movement, the first adjustable head piece 4 and the second adjustable head piece 5 between the two ends of described slide block 15 and valve body 6, can be formed.
Wherein, structure preferably three kinds of schemes of slide rail 14 and slide block 15, that is:
The first scheme: described slide rail 14 center is connected with plate washer 16, described slide rail 14 two ends are respectively arranged with the through hole being communicated with filler opening 1 and the first adjustable head piece 4, filler opening 1 and the second adjustable head piece 5.
First scheme: described slide block 15 length is greater than slide rail 14 length.
The third scheme: described slide rail 14 center is connected with plate washer 16, described slide rail 14 is evenly provided with several circular holes that is identical, that can be communicated with filler opening 1 and the first adjustable head piece 4, filler opening 1 and the second adjustable head piece 5.
Wherein, as shown in Figure 2, preferably, described through hole is rectangular, and described through hole is evenly provided with graduation line 17 for the first scheme, the ratio of convenient directly range estimation shunting.It should be noted that, when overlooking, the plate washer 16 of solid black be can't see, but in order to embody the position of plate washer 16, therefore signal is out.
First scheme, as long as ensure a part for slide block 15 or a bit can move along slide rail 14, but this kind of scheme, the ratio of shunting is not easy range estimation.
The third scheme, can by the ratio of the quantity range estimation shunting of circular hole.
Described spool 7 both sides are provided with the first spring 8 and the second spring 9, be provided with the first intercommunicating pore 10, be provided with the second intercommunicating pore 11 between described first oil outlet 2 and the second spring cavity volume 13 between described second adjustable head piece 5 and the first spring cavity volume 12.
Fluid is divided into two-way after entering filler opening 1, two oil pockets are entered respectively by the first adjustable head piece 4 and the second adjustable head piece 5, its pressure corresponds to P1 and P2 respectively, then flow out respectively by the first oil outlet 2 and the second oil outlet 3 through spool 7, enter in respective executive component, its outlet pressure corresponds to P3 and P4 respectively.Wherein, pressure is that the fluid of P1 enters into the second spring cavity volume 13 on the right side of spool 7 through the second intercommunicating pore 11, and the fluid that pressure is P2 enters into the first spring cavity volume 12 on the left of spool 7 through the first intercommunicating pore 10.When the first adjustable head piece 4 is identical with the second adjustable head piece 5 area, then P1 equals P2, and P3 equals P4.Changed the size of the first adjustable head piece 4 and the second adjustable head piece 5 by moving slider 15, and then change the different proportion of shunting, the different proportion of shunting can be regulated according to actual needs, structure is simple, cost is low, easy to operate, can meet more industrial requirements.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
