By adopting above-mentioned technological scheme, this adjustment type stopcock by inlet channel and outlet flow are adopted be obliquely installed and the position of inlet channel lower than the position of outlet flow, thereby when rotating by rotariling actuate handwheel band ovable valve stem, valve rod just can drive valve core rotation, the just state in separating of inclined via-hole of spool and valve seat, just can be communicated with inlet channel and the outlet flow of valve body by the inclined via-hole of valve seat, and valve rod is rotatably arbitrarily angled by band movable valve plug, just can well play the function of regulation valve body flow, and by inlet channel and outlet flow are adopted be obliquely installed and the position of inlet channel lower than the position of outlet flow, adopt the runner of low in and high out, thereby the fluid in valve body is by bottom-up promotion valve seat pressed spool, thereby can greatly increase valve seat and spool, sealing between valve interior wall and valve seat.
Further setting of the present utility model: the bottom of described valve rod arranges contiguous block, the side that described spool is connected with valve rod is provided with the connecting groove with described contiguous block adaptation, and the contiguous block of described valve rod bottom is inserted in the connecting groove of spool by interference fit.
By adopting above-mentioned technological scheme, be conducive to greatly increase the join strength of valve rod and spool, thereby can be good at avoiding making after valve rod band movable valve plug repeatedly rotates the joint of valve rod and spool to produce loosening phenomenon, to prevent from occurring in valve body the situation of leakage.
Further setting of the present utility model: the bottom center of described valve rod plug screw is provided with groove, is provided with a copper nut pad in described groove, this copper nut pad is anchored on valve rod.
By adopting above-mentioned technological scheme, the setting of this copper nut pad can make valve rod plug screw better be anchored on valve rod, in the time turning the rotation of driving handwheel actuate valve stem, can finely avoid valve rod plug screw and valve rod to produce the phenomenon of sliding.
Further setting of the present utility model: be provided with some O RunddichtringOs between described valve rod plug screw and valve rod.
By adopting above-mentioned technological scheme, can further improve the tightness connecting between valve rod plug screw and valve rod, and be conducive to further improve the sealing of whole valve inner structure.
Further setting of the present utility model: described spool and valve seat are by the alloyed steel of ion nitriding technique and make.
By adopting above-mentioned technological scheme, hardness, fatigue resistance, corrosion resistance and the red hardness of its spool and valve seat all have greatly improved, and make spool and valve seat more durable, are conducive to extend the working life of whole stopcock.
The beneficial effects of the utility model are: this adjustment type stopcock is by being made as inclination runner and the setting for low in and high out by the inlet channel of valve body and outlet flow, thereby the fluid in valve body is by bottom-up automatic promotion valve seat pressed spool, be conducive to greatly increase the sealing of valve inner structure, and screw rod is rotatably arbitrarily angled by band movable valve plug, can be good at playing the function of regulation valve body flow.
