Abstract
The utility model discloses a kind of bidirectional sealed butterfly valve, comprise valve body, upper in valve body, lower valve rod, be positioned at the valve seat of valve body, be installed on the dish plate in valve body and end cap, upper valve rod one end is placed in outside valve body, the dish plate of the other end in valve body connects, one end of lower valve rod coordinates fixing with end cap, it is characterized in that: the described lower valve rod the other end is connected and fixed by key and dish plate, described valve seat is tilting is arranged on upper and lower both sides in valve body, on valve seat, peripheral end face is sealing surface of seat, dish plate exterior edge face and tilting sealing surface of seat Spielpassung, described dish plate periphery ring face machine shaping is ring shaped slot structure, in ring channel structures, Sealing is installed, in linear contact lay between Sealing and tilting valve seat.The bidirectional sealed butterfly valve that the utility model obtains, valve components quantity is few, and assembly technology is simple, saves man-hour and material; Valve can reliably realize two way sealed zero leakage; Lower and the long service life of valve opening and closing moment of torsion.
Description
Technical field
The utility model relates to a kind of valve, particularly High Temperature High Pressure Y-shaped cut-off valve.
Background technique
The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of fluid.The forms of motion of valve rod, also has lifting rotation rod-type, and stop valve refers to the valve of closure member along the movement of valve seat center line.According to this mobile form of flap, the change of valve seat port is and flap stroke direct proportionality.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for the adjustment to flow.Therefore, such valve is suitable as and cuts off or regulate and throttling use very much.
Be applied to the dredging of thermal power plant, stop valve in drainage system, linear medium flow resistance is large, and noise is large, and the sealing surface between flap and valve body washes away by medium, can corrode sealing surface, shortens the life-span of valve use.
Model utility content
The purpose of this utility model provides to solve above-mentioned the deficiencies in the prior art the hydraulic control fast valve that a kind of long service life, structure are simple, can realize zero leakage two way sealed.
To achieve these goals, a kind of High Temperature High Pressure Y-shaped cut-off valve designed by the utility model, comprise valve body, valve rod, flap, support and transmission device, valve rod one end to be placed in valve body and to be fixedly connected with flap, the other end coordinates fixing with transmission device, support installing is between transmission device and valve body, it is characterized in that: described valve body is the Y valve body of tilting runner, self tightening structure is provided with in valve body, self tightening structure comprises floating valve gap, filler, hold-down grid, Gland arm-tie, floating valve gap is enclosed within above-mentioned valve rod exterior edge face, and valve gap lower end of floating is fixed on valve body the inner, filler is fixed between floating valve gap and valve rod, hold-down grid is arranged on filler upper end, floating valve gap exterior edge face is provided with Gland arm-tie, above-mentioned hold-down grid is threaded connection and is fixed on Gland arm-tie, float the pressure ring being provided with pressure sealing ring between valve gap lower end and valve body and being fixed on pressure sealing ring upper end, described flap lower end is provided with sealing surface, and sealing surface right opposite is provided with sealing seat
Preferably, described transmission device comprises many rotary types electric actuator or handwheel.
Preferably, described flap and valve rod installation place are provided with divided ring and are fixed on the gland splitting bad upper end.
The High Temperature High Pressure Y-shaped cut-off valve that the utility model obtains, beneficial effect is as follows: valve is connected with pipeline and adopts butt welding jointing type structure.2, valve lumen adopts pressure self-tightening structure, and chamber pressure more high sealing performance is better, has reliable sealability, and sealing surface has easy to wear, scratch, good seal performance feature, long service life.Compact structure, keying property is good, highly little, easy to maintenance; Be applicable to, on the pipeline of water, steam, oil product, weak erosive medium, to there is high pressure resistant, corrosion resistant feature.To be open-shut device (flap) to tilt the valve that an angle moves up and down along valve body sealing surface axis High Temperature High Pressure Y-shaped cut-off valve, and it is relatively short that valve rod opens and closes stroke, and have non-common opening reliably and cutting function. and can not make adjustments valve and use; Electric valve, adopt the many rotary types of electrical header, electric valve is driven by electric device for valve, makes valve rod increase, declines, thus drive the upper and lower motion of flap, open, closes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: valve body 1, valve rod 2, flap 3, support 4, transmission device 5, floating valve gap 6, filler 7, hold-down grid 8, Gland arm-tie 9, pressure ring 10, pressure sealing ring 11, valve seat 12, sealing surface 13, gland 14, divided ring 15.
