Description
Technical field
The present invention relates to hydraulic directio control valve field, more particularly to a kind of prismatic valve.
Technical background
Hydraulic directio control valve plays an important role in hydraulic circuit, in existing technology, the kind of prismatic valve
Class is single, although the effect that prismatic valve disclosed in the existing U of patent of invention CN 203516786 is selected with pressure, i.e., two
During the hydraulic oil of individual different pressures, prismatic valve can only turn on high-voltage oil liquid, but in actual application scenario, having plenty of need not
What high-voltage oil liquid passed through, and need low pressure fluid to pass through, the solution not had in existing technology.
The content of the invention
The present invention is being overcome the shortcomings of on above conventional art, proposes a kind of prismatic valve.
The specific content of the invention of the present invention is as follows：
Valve element is provided with a kind of prismatic valve, including valve body, valve body, is connected with the two ends of valve element on piston, piston and is provided with oil groove,
The middle part of valve element is provided with two seal grooves, and provided with two O-ring seals between valve element and valve body, described two are O-shaped close
Seal is arranged in the seal groove of valve body, and valve body upper end is provided with two oil inlets, and the lower end of valve body is provided with an oil-out；
As the preferred technical solution of the present invention, using threaded connection between described valve element and piston.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention by the oil inlet mode that is opened up on valve element and
The oil groove being provided with piston, can realize low-pressure hydraulic oil and prismatic valve when the hydraulic oil of different pressures enters prismatic valve
Oil-out is connected, and completes the selective circulation effect of low-pressure hydraulic oil.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Schematic diagram when Fig. 2 is present invention work.
In figure：1 is valve body, and 2 be piston, and 3 be O-ring seal, and 4 be valve element, and 5 be B oil inlets, and 6 be P oil-outs, and 7 be A
Oil inlet, 8 be oil groove.
Embodiment
In order that the solution of the present invention, advantage are more clearly understood, the present invention is carried out below in conjunction with the accompanying drawings further detailed
Describe in detail bright.
As shown in figure 1, the present invention is a kind of prismatic valve, it is made up of valve body 1, valve element 4, piston 2, O-ring seal 3, in valve
The inside of body 1 is provided with valve element 4, is connected with the two ends of valve element 4 on piston 2, piston 2 and is provided with oil groove 8, the middle part of valve element 4 is opened
There are two seal grooves, provided with two O-ring seals 3 between valve element 4 and valve body 1, two described O-ring seals 3 are arranged on close
In sealing groove, the upper end of valve body 1 is provided with A oil inlets 7 and B oil inlets 5, and the lower end of valve body 1 is provided with a P oil-out 6；Described piston
2 and described valve element 4 be to be connected through a screw thread.
As depicted in figs. 1 and 2, the valve element 4 of starting prismatic valve is in the centre position of the valve pocket of valve body 1, when A oil inlets 7
When flowing into the hydraulic oil of different pressures simultaneously with B oil inlets 5, if the hydraulic fluid pressure of A oil inlets 7 is higher than the hydraulic pressure of B oil inlets 5
Oil pressure, the high pressure liquid of A oil inlets 7 presses oil the low-pressure hydraulic that the hydraulic coupling acted in the right plane of piston 2 is more than B oil inlets 5
The hydraulic coupling that oil is acted in the left plane of piston 2, the valve element 4 of prismatic valve together with piston 2 and O-ring seal 3 to left movement,
During valve element is to left movement, when the low-pressure hydraulic oil of valve core movement to B oil inlets 5 can pass through the oil groove 8 on piston 2
When connecting P oil-outs 6, low-pressure hydraulic oil continuously will flow to P oil-outs 6 from B oil inlets 5, realize low-pressure hydraulic oil
Pass through, the function of high pressure liquid force feed cut-off.
Conversely, when the hydraulic fluid pressure of A oil inlets 7 is less than the hydraulic fluid pressure of B oil inlets 5, the high pressure liquid of A oil inlets 7
The hydraulic coupling acted in the right plane of piston 2 is pressed oil to act in the left plane of piston 2 less than the low-pressure hydraulic oil of B oil inlets 5
Hydraulic coupling, the valve element 4 of prismatic valve is moved right together with piston 2 and O-ring seal 3, during valve element is moved right,
When the low-pressure hydraulic oil of valve core movement to A oil inlets 7 can connect P oil-outs 6 by the oil groove 8 on piston 2, low-pressure hydraulic
Oil continuously will flow to P oil-outs 6 from A oil inlets 7.
Low pass prismatic valve of the present invention can realize different functions compared to traditional prismatic valve, and conventional prismatic valve is in difference
When the hydraulic oil of pressure is by prismatic valve, high pressure liquid force feed connection oil-out, and the prismatic valve of the present invention is to change oil inlet
Mode and under conditions of opening up oil groove on piston, realizes that low-pressure hydraulic oil connects oil-out.
