Description
Technical field
The utility model relates to a kind of overlapping sequence valve.
Background technique
Sequence valve is in the system with more than two duplexures, controls the valve of executive component sequence of movement according to the pressure etc. in loop, and wherein, overlapping sequence valve is a kind of conventional sequence valve.
The overlapping sequence valve of existing design, when having multiple oil outlet, all controls unlatching or the dissengaged positions of each oil outlet by spool, this kind of structure causes that sequence valve complex structure, cost are high, control deviation is large.
Model utility content
For the problems referred to above, the utility model provides a kind of overlapping sequence valve, controls unlatching or the dissengaged positions of each oil outlet, structure is simple, cost is low, control deviation is little respectively by spool and spring.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of overlapping sequence valve, comprise and there is certain thickness valve body, spool is provided with in valve body, it is characterized in that, described valve body side is provided with Pressure testing mouth, valve body opposite side is provided with spring, described spring afterbody is provided with adjusting screw rod, described spring is arranged on the side of valve body by outside valve gap, described spring end is fixedly installed a sealing block, described body base is provided with a filler opening, axial bore is provided with between described filler opening and Pressure testing mouth, described body top is provided with at least two oil outlets, be connected by connecting passage between described oil outlet, the salable insertion of described sealing block is also moved along connecting passage.
Preferably, described oil outlet is axially aligned.
Preferably, described connecting passage and sealing block are all cylindrical.
Wherein, spool is the unlatching of control section oil outlet and cut-out only, and spring controls unlatching and the cut-out of remaining part oil outlet, and this kind of structure, can make oil outlet be evenly distributed on the valve body of sequence valve, and need not be confined to around spool, more convenient control.Or identical oil outlet quantity, the design can make the volume of sequence valve and spool less, and structure is simple, cost is low, control deviation is little.
The beneficial effects of the utility model are: overlapping sequence valve is respectively by spool and spring to control unlatching or the dissengaged positions of each oil outlet, and structure is simple, cost is low, control deviation is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of overlapping sequence valve of the utility model;
The mark implication of accompanying drawing is as follows:
1: valve body; 2: Pressure testing mouth; 3: spool; 4: the first oil outlets; 5: the second oil outlets; 6: valve gap; 7: spring; 8: adjusting screw rod; 9: filler opening; 10: connecting passage; 11: axial bore; 12: sealing block.
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 overlapping sequence valve, comprise and there is certain thickness valve body 1, spool 3 is provided with in valve body 1, described valve body 1 side (left side in figure) is provided with Pressure testing mouth 2, and valve body 1 opposite side (right side in figure) is provided with spring 7, and the right side of described spring 7 afterbody and spring 7 is provided with adjusting screw rod 8, can spring 7 power of Regulation spring 7 by adjusting screw rod 8, and then control the state of each oil outlet.Described spring 7 is arranged on the side of valve body 1 by outside valve gap 6, namely described spring 7 end is fixedly installed a sealing block 12 near the side of spool 3, wherein, consider Environmental Conditions, preferably, the material of sealing block 12 is teflon, fluorine rubber etc., good sealing effect.
In Fig. 1, a filler opening 9 is provided with bottom valve body 1, axial bore 11 is provided with between described filler opening 9 and Pressure testing mouth 2, described valve body 1 top is provided with at least two oil outlets, 2 oil outlets are only shown in figure, be the first oil outlet 4 respectively and be connected by connecting passage 10 between the second oil outlet 5, first oil outlet 4 and the second oil outlet 5, the salable insertion of described sealing block 12 is also moved along connecting passage 10.Wherein, preferably, the substantially horizontal of oil outlet axially namely in figure is aligned, connecting passage 10 and sealing block 12 all cylindrical.
Filler opening 9 and the first oil outlet 4 are positioned at the upper and lower end of spool 3, and spool 3 controls the state of the first oil outlet 4, and spring 7 controls the state of the second oil outlet 5.Its specific works process is as follows:
After pressure oil enters valve body 1 from filler opening 9, first the left end of spool 3 is entered into through axial bore 11, act on the effective active area of spool 3, when spring 7 power of hydraulic coupling slightly larger than spring 7, sealing block 12 distance that moves to right is not enough to unlatching second oil outlet 5, and spool 3 moves to right, and fluid enters the first oil outlet 4 by filler opening 9, namely the first oil outlet 4 is opened, and the second oil outlet 5 cuts off; When pressure reaches certain value, after namely sealing block 12 moves to right certain distance, the second oil outlet 5 is also opened, be therefore connected to the first oil outlet 4 and the second oil outlet 5 device can according to the pressure in loop, sequentially to perform an action.
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.
