Technical field
The utility model is related to delivery valve field, and in particular to a kind of confession oil return and the multiple directional control valve deposited.
Background technology
The hydraulic multichannel conversion valve that existing market is generally used only has oil return opening.The hydraulic multichannel of this only oil return opening is changed
Oil sources can not be provided to other equipments again to valve, function is relatively simple.And in real work, many times often only
Increase operating mechanism in the case of having an oil feed pump, now, just seem at a loss what to do in face of traditional multiple directional control valve.If
There is a kind of hydraulic multichannel conversion valve also to there is one Pb mouthfuls (this mouth can provide oil sources for other valves), then problem just becomes to meet
Sword and solve, system just can greatly reduced with efficient and convenient switching between other valve fuel feeding or fuel cut-off by this valve
This is caused, the flexibility of the working environment of increase hydraulic system reply conversion.
Utility model content
In summary, in order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model is to provide one
Plant the multiple directional control valve for supplying oil return and depositing.
The technical scheme that the utility model solves above-mentioned technical problem is as follows:A kind of confession oil return and the multiple directional control valve deposited,
Including valve body, centre bore, fuel feeding road and back oil road are provided with valve body, the centre bore is axially arranged along the valve body, and
And the front end of the centre bore is oil inlet, the one end and the end of the centre bore in the fuel feeding road and the back oil road cross
Form threeway intersection, the other end in the fuel feeding road and the back oil road is respectively in the opposite direction and towards prolonging on the outside of valve body
Stretch, be communicated with the oil-feed port of the threeway intersection, the confession in the valve body at the position of the correspondence threeway intersection
The axis of hydraulic fluid port is overlapped with the axis of the centre bore, is supplied in the oil-feed port provided with plug or for downward one-level valve
The transit joint of oil.
The beneficial effects of the utility model are:By improving the structure of conventional hydraulic banked direction control valves, some are allowed to be in hydraulic pressure system
The multiple directional control valve united in series loop need to only increase when needing to next stage valve fuel feeding in the exit of multiple directional control valve
One transit joint be can be achieved with, and transit joint is removed when not needing fuel feeding, and be substituted for hydraulic pressure plug, be saved more
Change time and the cost of multiple directional control valve.
On the basis of above-mentioned technical proposal, the utility model can also do improvement further below:
Further, it is provided with the valve body in the oil-feed port and fuel feeding road is still kept after transit joint in connection and is returned
The annular groove of oil duct connection, the annular groove is in the intersection of the fuel feeding road and the back oil road.
Using having the beneficial effect that for above-mentioned further technical scheme:When to next stage valve fuel feeding, it is ensured that valve body is just
Normal oil return.
Further, the transit joint is threaded in the oil-feed port, and the front end of the transit joint is in
In the end of the centre bore, its center is provided with the through hole of downward one-level valve fuel feeding.
Further, the front end of the transit joint, which is provided with, is used to strengthen the O-ring of sealing.
Using having the beneficial effect that for above-mentioned further technical scheme:Prevent the generation of draining.

Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in Fig. 2 a kind of confession oil return and the multiple directional control valve deposited, including valve body 1, in valve body 1 provided with centre bore 2,
Fuel feeding road 3 and back oil road 4, the centre bore 2 are axially arranged along the valve body 1, and the front end of the centre bore 1 is oil-feed
Mouth 5, the one end in the fuel feeding road 3 and the back oil road 4 crosses to form threeway intersection 6 with the end of the centre bore 2, described
The other end of fuel feeding road 3 and the back oil road 4 extends in the opposite direction and towards the outside of valve body 1 respectively, right in the valve body 1
The oil-feed port of the threeway intersection 6, the axis of the oil-feed port and institute are communicated with the position for answering the threeway intersection 6
The axis for stating centre bore 2 is overlapped, and plug or the transit joint for downward one-level valve fuel feeding are provided with the oil-feed port
