With exploitation demand of the mankind to mineral resources, the demand of such product is also continuously increased, to its performance requirement
Improve constantly.In conventional application valve body structure, radial hole is mostly straight hole, and the hydraulic oil on the outside of application valve body quickly moves in valve body
Shi Buneng is rapidly entered on the inside of valve body completely, and so as to cause valve body interim card easily occur, and this not only to produce in operation
Raw larger noise, and larger abrasion is produced to equipment, influence its service life.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided the hydraulic oil on the outside of a kind of application valve body is quickly transported in valve body
It can be rapidly entered completely when dynamic on the inside of valve body, valve body is not easy interim card occur, will not produce larger noise, equipment is produced smaller
Abrasion, ensure the control valve of service life.
The object of the present invention is achieved like this：
A kind of control valve, it includes the valve body of the tubulose of lateral arrangement, and the outer wall of the valve body offers to valve body inner side
Oblique right inclined hole, first annular groove of circle is provided with the valve interior wall corresponding to the inner of inclined hole, the internal diameter of the first annular groove is big
In the stage casing internal diameter of valve body, the right-hand member outer ring of the valve body offers multiple the first horizontal blind holes, the right side of the valve body to the left
End centre circle is provided with oil storage tank, and the right-hand member for having the blind hole of part first 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 3rd blind hole of a circle to the right is offered on second annular groove, the left end of the 3rd blind hole connects with valve inner, the right side of the 3rd blind hole
The left end laterally with multiple first blind holes is held to connect.
As a preferred embodiment, the valve inner of tubulose is the stepped hole with multistage, 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-hand member.
As a preferred embodiment, the outer end of inclined hole is provided with enlarging.
As a preferred embodiment, the right-hand member lower semisection outer ring of the valve body is further opened with multiple the second horizontal blind holes, second
The stage casing of blind hole connects with the outside of valve body.
Compared with prior art, the beneficial effects of the invention are as follows：
There is control valve of the present invention hydraulic oil on the outside of application valve body can rapidly enter valve completely when valve body quickly moves
Internal side, valve body are not easy interim card occur, improve service life of equipment about more than 20%, will not produce larger noise, improve
The oil storage capacity of application valve body so that equipment performance is substantially improved, and produces smaller abrasion to equipment, ensures service life
Advantage.

Embodiment
Referring to Fig. 1-Fig. 3, a kind of control valve of the present invention, it includes the valve body 1 of the tubulose of lateral arrangement, tubulose
The inside of valve body 1 is the stepped hole with multistage, and the left end opening of valve body 1 is big, and the right-end openings of valve body 1 are small, in the stage casing of valve body 1
Footpath is between left end and right-hand member, and the rear side outer wall of the valve body 1 offers an oblique right inclined hole 2 to valve body inner side, tiltedly
The outer end in hole 2 is provided with enlarging 3, and first annular groove of circle 4, the first ring are provided with the inwall of valve body 1 corresponding to the inner of inclined hole 2
The internal diameter of groove 4 is more than the stage casing internal diameter of valve body 1, and the right-hand member outer ring of the valve body 1 offers multiple the first horizontal blind holes to the left
