Abstract

The utility model relates to an oil path board used for assembling a plurality of unloading valves. A plurality of flowing-in channels respectively communicated with the hydraulic oil inlets of the unloading valves and a plurality of flowing-out channels respectively communicated with the hydraulic oil outlets of the unloading valves are mainly penetrated and formed inside a body; moreover, scavenge channels respectively communicated with the flowing-out channels are additionally penetrated and formed inside the body; the two ends of the scavenge channels are respectively formed with scavenge ports on the body; the unloading valves after being assembled on the oil path board can respectively flow into the flowing-out channels through the hydraulic oil of each unloading valve; and the hydraulic oil of each flowing-out channel can flow together into the scavenge channels, and then flow back to an oil tank through two pipelines connected between the two scavenge ports of the scavenge channels and the oil tank. Only two pipelines are needed to be connected between the oil path board and the oil tank no matter the number of the unloading valves is more or less, thereby reaching the purposes of saving the using cost of the pipelines and avoiding disordered pipelines.

Description

Oil-way board

Technical field

The utility model is about a kind of oil-way board, and it can carry valve assembling setting for a plurality of letting out, and is provided with the shared pathway that can communicate with the hydraulic oil outlet of respectively letting out year valve in inside, is connected in the pipeline quantity of letting out the hydraulic oil outlet of carrying valve thereby can reduce.

Background technique

In pressurized oil system, letting out a year valve is a kind of control valve commonly used, can be arranged at as between breaks such as oil hydraulic cylinder and the fuel tank, whether get back to fuel tank in order to control by the hydraulic oil behind the break, therefore this is let out and carries valve, be connected with pipeline respectively between itself and the break, and and fuel tank between also be connected with pipeline respectively;

The above-mentioned usage quantity that carries valve of letting out, demand on the design of the oil circuit of pressurized oil system is decided, may use single or a plurality of letting out to carry valve, if a plurality of situations of carrying valve of letting out, then each lets out that carry between valve and the fuel tank all must connecting pipeline, be with, in case it is many more to let out the usage quantity that carries valve, then pipeline quantity also increases thereupon, takes up room and shortcoming that pipeline is in disorder thereby derive to have.

Summary of the invention

Because in case employed the letting out of pressurized oil system carried the increase of valve quantity, the pipeline that also thereupon increases of the quantity in disorder shortcoming that is difficult to arrangement that will take up room and seem then, the utility model provides an oil-way board, its inside is provided with hydraulic oil channel and can lets out for plural number and carry a valve and use jointly, reduce according to this to be connected in and let out the pipeline quantity of carrying valve, thereby solve above-mentioned shortcoming.

Based on above-mentioned purpose, the technical solution of the utility model is;

Oil-way board, it is characterized in that: include a body, described body interior wears and is formed with a plurality of flow channels, the flow pass of one drain passage and corresponding flow channel quantity, wherein a side of running through body respectively, the two ends of each flow channel is formed with a first-class inlet and one second inflow entrance, the side that body is run through at the two ends of described drain passage respectively is formed with an outfall, the side that one end of each flow pass runs through body respectively is formed with an outflow opening, the first-class inlet of described outflow opening and flow channel is positioned at the same side of body, and the other end of described each flow pass is communicated in drain passage respectively.

The oil-way board of the utility model can cooperate a plurality of letting out to carry the valve use, respectively letting out a year valve system is assembled on the side that is formed with first-class inlet and outflow opening on the oil-way board, and its hydraulic oil inlet is to communicate with corresponding first-class inlet, the outlet of its hydraulic oil then communicates with corresponding outflow opening, and desire is carried the hydraulic oil that valve is got back to fuel tank by respectively letting out, system flow to let out after each second inflow entrance enters flow channel carries valve, and in by let out carry valve after again in outflow opening enters flow pass, and the hydraulic oil that enters each flow pass can conflux in drain passage, be back to fuel tank via two pipelines between outfall that is connected in the drain passage two ends and the fuel tank again, hence one can see that, no matter let out and carry valve quantity number, between oil-way board and fuel tank, all need only be connected two pipelines, therefore can reach the user cost of saving pipeline and avoid the in disorder purpose of pipeline.

Embodiment

The oil-way board of the utility model shown in Fig. 1～4, it includes a body 10, this body 10 has a leading flank 11, a trailing flank 12, a left surface 13, a right flank 14 and a bottom surface 15, body 10 inside wear the flow pass 18 that is formed with a plurality of flow channels 16, a drain passage 17 and corresponding flow channel quantity, wherein:

The two ends of each flow channel 16 are run through respectively on the side of body 10 and are formed with a first-class inlet 161 and one second inflow entrance 162, in present embodiment, this first-class inlet 161 is 162 bottom surfaces 15 of running through body 10 of leading flank 11, the second inflow entrances of running through body 10;

The two ends of drain passage 17 are run through respectively on the side of body 10 and are formed with an outfall 171, and in present embodiment, this two outfall 171 is the left surface 13 and right flank 14 that runs through body 10 respectively;

One end of each flow pass 18 runs through on body 10 sides and is formed with an outflow opening 181, the first-class inlet 161 of this outflow opening 181 and flow channel 16 is positioned at the same side of body 10, and the other end of each flow pass 18 is communicated in described drain passage 17 respectively, in present embodiment, this outflow opening 181 runs through the leading flank 11 of body 10.

The oil-way board of the utility model system collocation first letting out and carry a valve 20A or second and let out and carry valve 20B and use shown in Fig. 5 A and Fig. 5 B, that can arrange in pairs or groups first lets out and carries valve 20A and second and let out the quantity of the carrying valve 20B quantity corresponding to flow channel 16 and flow pass 18, this first is let out and carries a valve 20A and second and let out and carry a valve 20B and have hydraulic oil inlet 21 and one hydraulic oil respectively and export 22, wherein the first hydraulic oil inlet 21 of letting out year valve 20A remains with hydraulic oil outlet 22 and communicates, second lets out and carries a valve 20B and then have hydraulic oil inlet 21 and export 22 with hydraulic oil and be the two condition that communicates or do not communicate, and second lets out a year valve 20B has a guide port 23 in addition, and this guide port 23 can enter second for hydraulic oil in addition and let out the switching of carrying between the two condition that communicates or do not communicate with control in the valve 20B;
