The through hole that axially and is radially provided with connection box house and fluid passage of the axial or tail end of described standing part tail end.
Described one-way valve comprises the ring-type valve seat being located in fluid passage and the Elastic valve core coordinating with valve seat.
Described Elastic valve core by steel ball spool or plasticity taper spool and be located at steel ball spool or plasticity taper spool and standing part between spring form.
Described valve seat is provided with conical surface and coordinates with steel ball spool or plasticity taper spool.
In the tail end of described standing part, be provided with ring-spring seat, described spring is located between spring seat and steel ball.
The end that the surrounding of described active part bar portion is provided with seal ring or bar portion is provided with sealing block.
The bar portion of described active part is connected with the open-top screw thread of standing part.
The head of described active part is provided with groove or adopts polygonal.
The beneficial effects of the utility model:
1, owing to adopting the composite structure of standing part and active part composition, can realize sealing by the elastic valve of standing part under normal circumstances, prevent that machine oil from flowing out, once there is lubricating oil leakage in elastic valve, active part can be used as second sealing configuration and further guarantees oil-proof, solve the risk of seepage completely, avoided engine to damage because of leakage of oil, the phenomenon that in Vehicle Driving Cycle, leakage of oil will be sued and laboured.
2, active part covers on standing part, can prevent that mud dirt from entering in standing part.
3, because magnetic substance is located on active part, the one, metal spool can be strained, increase sealability, make its difficult seepage, between spool and active part, form vacuum; The 2nd, can be iron impurity absorption the bottom at casing; take out after active part; now magnetic force is removed; standing part is carrying magnetic not, and while draining the oil, the iron impurity in casing is discharged with waste oil; cleaning impurity becomes easy; can effectively solve iron filings impurity in prior art and be adsorbed on all the time the problem of easily stopping up and affect sealing on jettison gear, can effectively protect engine and the every part of box house, extend the engine working life of automobile and equipment.
The utility model is except for draining the oil, can also be used for other fluid or gas release and filling.
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.
