Abstract
The utility model provides a dual-purpose throttle stop valve which comprises a valve body, a valve seat, a throttle valve clack, a stop valve clack, a valve rod, a valve deck, stuffing and a hand wheel. The valve body and the valve deck are firmly connected together through double-screw bolts and nuts so that a valve cavity can be formed in the inner portion. The valve seat is arranged in the valve body. The hand wheel is arranged at the top end of the valve rod. The valve rod penetrates through the valve deck and extends inside the valve cavity. The bottom end of the valve rod is connected with the stop valve clack. The lower end of the stop valve clack is connected with the throttle valve clack. The throttle valve clack is arranged on the valve seat. A soft sealing ring is arranged between the stop valve clack and the throttle valve clack. A first O-type ring is arranged between the throttle valve clack and the valve seat. According to the dual-purpose throttle stop valve, a sealing face of each valve clack is separated from a throttle adjusting face, so that the independent multi-stage throttle and stop functions are achieved, the sealing faces are effectively protected against direct scouring and corrosion action by fluid media with the high pressure difference and high speed, the throttle capacity and the reliability of valve sealing are improved, and meanwhile the service life of the sealing structure is prolonged.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of double-action throttling stop valve.
Background technique
At present, oil, gas industry more application double-action throttling stop valve.But in the double-action throttling stop valve, valve clack sealing surface is substantially all close with the throttling adjusting range at present, and this makes sealing surface easily be subject to directly washing away and corroding of High Pressure Difference, high-velocity fluid medium, affects sealing effect, and the working life of sealing configuration.
The model utility content
The utility model provides a kind of good sealing effect, long double-action throttling stop valve of life-span for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of double-action throttling stop valve is characterized in that, comprises valve body, valve seat, throttling flap, cut-off flap, valve rod, valve gap, filler, handwheel, and valve body and valve gap link together by double-screw bolt and fastening nuts, the inner valve pocket that forms; Valve seat is arranged in valve body, and handwheel is arranged on the top of valve rod, and valve rod runs through valve gap, stretches into valve pocket inside; The bottom of described valve rod is connected with the cut-off flap, and the lower end of cut-off flap is connected with the throttling flap, and the throttling flap is arranged on valve seat; Be provided with the soft seal circle between described cut-off flap and throttling flap; Be provided with an O type circle between throttling flap and valve seat; Be provided with a valve core housing in valve pocket, circumferentially be provided with twice the 2nd O type circle along the cut-off flap between described cut-off flap and valve core housing.
Further setting of the present utility model is, is provided with equalizing orifice on described cut-off flap.
Further setting of the present utility model is, is equiped with grease pouring valve on described valve rod.
Further setting of the present utility model is, is provided with twice the 3rd O type circle between valve core housing and valve body.
Further setting of the present utility model is, also is provided with a support between described valve gap and handwheel.
Further setting of the present utility model is, is provided with the 4th O type circle between valve core housing and valve gap.
Double-action throttling stop valve described in the utility model separates valve clack sealing surface with the throttling adjusting range; independent multistage throttle and cutoff function have been formed; effectively protected High Pressure Difference, high-velocity fluid medium to directly the washing away of sealing surface, corrosive action; improve the reliability of throttling capacity and valve seal, extended simultaneously the working life of sealing configuration.
