Portion side is installed with second spring, and traveller is slidably connected with check cavity, and traveller one end is fixedly connected with second spring,
Traveller one end is provided with groove, and check cavity is connect by oil transportation hole with oil inlet, and filter screen is installed with inside oil inlet, oil
Enter from oil inlet, then passes through filter screen and oil inside is removed in impurity, pass to check cavity using oil transportation hole, oil pressure is more than
The dynamic traveller of pushing of second spring is moved to the side for having second spring, and oil is driven upwards by the groove on traveller surface, works as oil
When pressure is insufficient, the restoring force that second spring generates moves traveller to the other side, groove is pushed to side, the oil at the top of check cavity
Traveller cannot be pushed to move, oily reflux can be prevented.
2, the present invention is provided with oil outlet and oil inlet by valve body, and oil outlet one end is provided with sliding chamber, and sliding intracavitary portion is solid
Dingan County is equipped with fixed plate, and fixed plate is provided with several first through hole, and fixed plate side is installed with the first spring, slip pipe with
Sliding chamber is slidably connected, and slip pipe one end is installed with cone valve, and the first spring is fixedly connected through slip pipe with cone valve inner bottom,
And cone valve outer surface is provided with several the second through-holes, oil enters from oil inlet, and cone valve is then jacked up by check cavity and is moved up,
Oil enters sliding chamber, then flows to slider tube from second through-hole on cone valve surface, subsequently the first through hole stream Jing Guo fixed plate
It is flowed out to oil outlet, when oil pressure is too small, the restoring force that the first spring generates pushes slip pipe and cone valve to push down on, and prevents oil from returning
Stream.

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 one-way conduction valve body, including valve body 1, slip pipe 2,
Check cavity 3 and traveller 4, the valve body 1 are provided with oil outlet 5 and oil inlet 6, and 5 one end of the oil outlet is provided with sliding chamber 7, and sliding
Fixed plate 8 is installed with inside chamber 7, the fixed plate 8 is provided with several first through hole 9, and 8 side of fixed plate is fixedly mounted
There is the first spring 10, the slip pipe 2 is slidably connected with sliding chamber 7, and 2 one end of slip pipe is installed with cone valve 11, first bullet
