Fig. 2 is the connection diagram of the utility model and oil pump.
Description of reference numerals: block 1, valve body 2, spool 3, adjusting screw 4, spring 5, flow-off 6, filler opening 7, oil outlet 8, cavity 9, sealing surface 10, pipeline 11, oil return contiguous block 12, oil pump 13, locking nut 14.
Embodiment
Below in conjunction with Figure of description and embodiment, embodiment of the present utility model is described in further detail:
With reference to a kind of New-type safety valve of Fig. 1, Fig. 2, comprise the valve body 2 with block 1, in described valve body 2, be provided with the spool 3 coordinated with described valve body 2 activity, wherein, the rectangular shape of described valve body 2, described valve body 2 is aluminum alloy valve body; The rounded shape of described block 1, described block 1 is aluminum alloy cap, and the present embodiment, compared with the safety valve of conventional cast structure, has volume little, lightweight, can be applicable to being arranged on oil pump, and install, convenient disassembly; In addition, above-mentioned other component such as spool 3 grade can adopt steel matter to make, adjusting screw 4 is provided with in described valve body 2, here adjusting screw 4 has regulating action, easy to use, described adjusting screw 4 extends in described spool 3, is provided with spring 5 in described spool 3, described spring 5 is socketed in described adjusting screw 4, and described adjusting screw 4 is provided with locking nut 14; Described valve body 2 is provided with flow-off 6, described flow-off 6 communicates with described spool 3, wherein, here flow-off 6 is a through hole, specifically can squeeze into when adding formula on valve body 2 and extend to spool 3, the underpart of described valve body 2 be respectively equipped with filler opening 7 and oil outlet 8, described spool 3 and be provided with cavity 9 between described filler opening 7 and oil outlet 8, this cavity 9 is oil stream cavity, and described cavity 9 communicates with described filler opening 7 and oil outlet 8.
With reference to Fig. 1, the bottom of described spool 3 is provided with conical sealing surface 10, and the object of design is like this, can strengthen the sealing effect between spool 3 and described valve body 2 further by conical sealing surface 10, avoids occurring entering phenomenon outside oil stream.
With reference to Fig. 2, the flow-off 6 of described valve body 2 is connected with the filler opening of oil return contiguous block 12 with oil pump 13 by pipeline 11 successively, wherein, here pipeline 11 is stainless steel pipeline, and oil return contiguous block 12 is aluminum alloy material, and the order of design is like this, light weight, volume is little, easy for installation.
