Description
Technical field
The utility model belongs to valve technology field, in particular, relates to a kind of ball valve body.
Background technique
Ball valve is a kind of open-shut device, and spheroid is driven by valve rod, and around the valve that ball valve axis rotates.Also can be used for the regulating and control of fluid, wherein firmly seal between V type ball valve its V type ball core and metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the medium of fibre-bearing, a small solid material etc.And multi-pass ball valve not only can the interflow of control media, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.Ball valve is classified: pneumatic ball valve, electric ball valve and manual ball valve.
Ball valve comprises the valve rod of valve body and spool and control spool; for the ease of manufacturing, generally can be connected with valve body connector on valve body, and valve body connector and valve body are when being connected; but usually centering difficulty can be there is, the generation of the problems such as the butt plate distortion caused owing to connecting skew.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ball valve body, by this ball valve body, by being arranged on the positioning means on the butt plate on valve body, achieving when ball valve body docks with valve body connector and can centering be connected quickly and accurately.
For achieving the above object, the utility model provides following technological scheme: a kind of ball valve body, comprise flow-path tube and flow control pipe, described flow control pipe is vertically connected at the middle part of flow-path tube, the other end of described flow control pipe relative current deferent is provided with valve gap land, the two ends of flow-path tube are provided with valve body land, described valve gap land is provided with the first concentric positioning boss, the end face of described first positioning boss is provided with some the first locating slots outwards radiated in the center of circle, described valve body land is provided with the second concentric positioning boss, the end face of described second positioning boss is provided with some the second locating slots outwards radiated in the center of circle.
By adopting technique scheme, by the first positioning boss, the valve gap connected with valve gap land can be felt relieved fast, being achieved the circumference location of valve gap by the first locating slot; Achieved the centering of the valve body attachment docked with it by the second positioning boss, achieved the axially locating of valve body attachment by the second locating slot; The quick connection so just achieved between valve body and interfacing part with matching coordinates, and prevents valve body connector and valve body when being connected, the generation of the problems such as the butt plate distortion caused owing to connecting skew.
The utility model is set to further: described valve body land is also provided with concentric seal groove, and the diameter of described seal groove is greater than the diameter of the second positioning boss and is less than the direct of valve body land.
By adopting technique scheme, by placing seal ring in seal groove, realize the sealability between parts that valve body docks with it.
The utility model is set to further: described valve body land is provided with the flange hole of uniform circumference distribution, and be also provided with stiffening rib between valve body land and flow-path tube, described stiffening rib is located at immediately below flange hole.
By adopting technique scheme, the parts that valve body land docks with it provide firm attachment force by flange hole, so the periphery of flange hole is stress concentration portion position, by being arranged on the stiffening rib below flange hole, add the whole service life of valve body, add the non-deformability of valve body land greatly.
Compared with prior art, the utility model has the advantage of: the centering being achieved the parts docked with valve body by the first positioning boss and the second positioning boss, prevent the generation of the problems such as the butt plate distortion caused owing to connecting skew; By the first locating slot and the second locating slot, the circumference achieving the parts docked with valve body is located; The connection sealing of valve body is added by seal groove; By being arranged on the stiffening rib immediately below flange hole, add the non-deformability of valve body butt plate.
