Raw larger noise, and larger abrasion is generated to equipment, influence its service life.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency, the hydraulic oil provided on the outside of a kind of application valve body are fast in valve body
It can be rapidly entered completely on the inside of valve body during speed movement, valve body is not easy interim card occur, will not generate larger noise, and equipment is generated
Smaller abrasion ensures the control valve of service life.
What the purpose of this utility model was realized in：
A kind of control valve, it includes the valve body of the tubulose of lateral arrangement, and the outer wall of the valve body is offered to valve body inside
The inclined hole on the oblique right side is provided with first annular groove of circle at the valve interior wall corresponding to the inner end of inclined hole, and the internal diameter of the first annular groove is big
In the stage casing internal diameter of valve body, the right end outer ring of the valve body offers multiple the first lateral blind holes, the right side of the valve body to the left
End centre circle is provided with oil storage tank, and the right end for having the first blind hole of part is connected with oil storage groove location, and left section of the valve body is inwardly
Second annular groove of circle is provided with, the second annular groove includes the larger crosspiece of left section of internal diameter and the diminishing oblique section of right section of internal diameter,
The third blind hole of a circle to the right is offered on second annular groove, the left end of third blind hole is connected with valve inner, the right side of third blind hole
The left end outward with multiple first blind holes is held to connect.
As a preferred embodiment, the valve inner of tubulose is with multistage stepped hole, the left end opening of valve body is big, valve body
Right-end openings are small, and the stage casing internal diameter of valve body is between left end and right end.
As a preferred embodiment, the outer end of inclined hole is provided with flaring.
As a preferred embodiment, the right end lower semisection outer ring of the valve body is further opened with multiple the second lateral blind holes, second
The stage casing of blind hole is connected with the outside of valve body.
Compared with prior art, the beneficial effects of the utility model are：
The utility model control valve have application valve body on the outside of hydraulic oil when valve body quickly moves can completely quickly into
Entering on the inside of valve body, valve body is not easy interim card occur, improves service life of equipment about more than 20%, will not generate larger noise,
Improve the oil storage capacity of application valve body so that equipment performance is substantially improved, and smaller abrasion is generated to equipment, ensures to use the longevity
The advantages of life.

Specific embodiment
Referring to Fig. 1-Fig. 3, the utility model is related to a kind of control valve, it includes the valve body 1 of tubulose of lateral arrangement, pipe
1 inside of valve body of shape is with multistage stepped hole, and the left end opening of valve body 1 is big, and the right-end openings of valve body 1 are small, in valve body 1
For section internal diameter between left end and right end, the rear side outer wall of the valve body 1 opens up the inclined hole there are one the oblique right side to valve body inside
2, the outer end of inclined hole 2 is provided with flaring 3, and first annular groove of circle 4 is provided at 1 inner wall of valve body corresponding to the inner end of inclined hole 2, the
The internal diameter of one annular groove 4 is more than the stage casing internal diameter of valve body 1, and the right end outer ring of the valve body 1 offers multiple lateral first to the left
Blind hole 5, the right end lower semisection outer ring of the valve body 1 are further opened with multiple the second lateral blind holes 6, the stage casing of the second blind hole 6 with
The outside connection of valve body 1, the right end centre circle of the valve body 1 are provided with oil storage tank 7, right end and the oil storage for having the first blind hole of part 5
7 position of slot is connected, and left section of the valve body 1 is inwardly provided with second annular groove of circle 8, the second annular groove 8 include left section of internal diameter compared with
