Technical field
The present invention relates to a kind of valve body, be specifically related to a kind of adjustment type stopcock.
Background technique
In various types of valves, stopcock is be most widely used a kind of, and that stopcock has is simple in structure, open and close the advantages such as rapid, easy to operate, fluid resistance is little.In oil, gas exploitation course and on the transfer line of oil, rock gas, product oil, in hydraulic engineering, be all used widely.Yet, existing stopcock generally can only by by the direct 90-degree rotation of spool with realize inlet channel and outlet flow communicate and existing runner is generally straight-through type flow passage and makes it not possess the function of Flow-rate adjustment, moreover, in prior art in order to improve the sealing effect of stopcock, conventionally below spool, be provided with valve seat, again between valve interior wall and valve seat, between valve seat and spool, be provided with lining etc. and carry out encapsulation process, so not only sealing configuration is comparatively complicated, difficulty of processing is large, cost is higher, assembling and dismounting are comparatively loaded down with trivial details, and and do not reach good sealing effect.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the invention provides that a kind of structure is comparatively simple, good seal performance and there is the adjustment type stopcock of good flow regulating function.
In order to solve the existing problem the present invention of background technique, adopted following technological scheme: a kind of adjustment type stopcock, comprise valve body, valve rod, spool, valve seat, valve rod plug screw and driving handwheel, the both sides of described valve body are respectively arranged with inlet channel and outlet flow, described spool is fixedly connected on the bottom of valve rod, described valve seat is closely set in the below of spool, described valve rod plug screw is sheathed on valve rod, described driving hand wheel rotating is connected on valve rod, the inlet channel of described valve body and outlet flow all adopt be obliquely installed and the position of inlet channel lower than the position of outlet flow, on described valve seat, be provided with the inclined via-hole that can be communicated with described inlet channel and outlet flow, described inclined via-hole is tilted to the outside, one end near spool by the middle part away from spool one end, the sectional shape of described spool and the valve seat through hole that tilts is suitable near a side of spool.
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 inclined via-hole of spool and valve seat is the state in separating just, inlet channel and the outlet flow that by the inclined via-hole of valve seat, just can be communicated with valve body, 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.
The further setting of the present invention: 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.
The further setting of the present invention: 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, when 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.
The further setting of the present invention: 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.
The further setting of the present invention: described spool and valve seat are by the alloyed steel of ion nitriding technique and make.
By adopting above-mentioned technological scheme, the hardness of its spool and valve seat, fatigue resistance, corrosion resistance and red hardness all have greatly improved, and make spool and valve seat more durable, are conducive to extend the working life of whole stopcock.
Beneficial effect of the present invention is: this adjustment type stopcock is by by the inlet channel of valve body with outlet flow is made as inclination runner and be the setting of low in and high out, 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.
