This hydraulic shock is limited with overflow valve, it is in the majority with plug-in overflow valve to pursue integration and miniaturization, it is former according to work
Reason and structure composition are broadly divided into pilot-operated type structure and direct dynamic structure, and in the prior art pilot operated compound relief valve when in use its
Oil pressure is generally large, has prodigious defect when in use for example in some places：
1, it is used extensively in pilot operated compound relief valve in the prior art, but existing pilot operated compound relief valve, due to only with single
Thimble carries out pressure control, causes its pressure control ability low so as to need multiple overflow valves in the equipment that some need bigger oil pressure
It uses simultaneously, so cannot be satisfied needed for the prior art.
2, be all in the blocking of pressure relief opening in the prior art blocked using nut, but for a long time in use, by
In the erosion of deep fat be likely to result in its screw thread be difficult to take out cause can not pressure release, there is dangerous possibility, so cannot be satisfied
Letter has needed for technology.

Side is all connected with limited block, and second back-moving spring is connected on the limiting slot below limited block, and pressurize work is played in low oil pressure
With deep fat is discharged by through-hole again when oil pressure is excessive, instead of pressure control energy under single thimble pressure control state in holding oil pressure bigger
The low situation of power.
2, the present invention is threaded with pipe lid for one section by relief tube, only meeting after replacing the nut of script that deep fat is corroded
It causes to damage on one side in pipe lid, the possibility for carrying out pressure release can not be taken out without causing.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of deep fat overflow valve, including valve body 1, enter oil pipe 2,
Flowline 3 and relief tube 4,1 middle part side of the valve body are connected with into oil pipe 2, and 1 other side of the valve body is connected with relief tube 4,
