Abstract
The invention relates to a sleeve type butterfly valve. The sleeve type butterfly valve comprises a valve body, a slide sleeve, a valve plate and a gear shaft, wherein the slide sleeve is arranged in the valve body, and is in a cylinder shape; an outer circle of the slide sleeve is provided with a convex annular edge and two symmetric gear racks and long holes, and a convex circular truncated cone is arranged in the circle. The sleeve type butterfly valve has the beneficial effects that the existing butterfly valve is additionally provided with the slide sleeve, a gear and a driving shaft, the friction seal flow blocking of the existing butterfly valve is changed into the cutoff seal flow blocking, and the friction step in the mechanical movement process of the existing butterfly valve is eliminated; the labor is saved in operation, the pressure-resistant property is good, the service life is long, and the like; the sleeve type butterfly valve is suitable for different sizes of pipelines.
Description
Technical field
The present invention relates to a kind of butterfly valve.
Background technology
Common butterfly valve, is generally divided into soft sealing butterfly valve and hard seal butterfly valve.Although both ranges of application are different, but its structure and operation principle are identical.The friction that the control of convection cell is all on the inner headed face of outer rim and the valve body utilizing valve plate obtains.Friction therein, for large-scale or medium-sized butterfly valve, is not only operation effort, and also contributes to their pressure performance and used life.
Summary of the invention
It is an object of the invention to provide a kind of rapid operation, life-span length and robust Shell butterfly valve.
For achieving the above object, present invention employs following technical scheme:
A kind of Shell butterfly valve, including valve body, sliding sleeve, valve plate and gear shaft, has sliding sleeve in valve body；Sliding sleeve is cylindrical, bossed ring-type limit and two symmetrical tooth bars and elongated hole, bossed ring-type round platform in circle on cylindrical.
Beneficial effects of the present invention: add sliding sleeve, gear and driving axle on the basis of existing butterfly valve and form, dammed by existing butterfly valve friction sealed and change cut-off sealing into and dam, eliminate the friction link in existing butterfly valve mechanical movement, thus there is the advantages such as rapid operation, good pressure-resistant performance, life-span length, it is adapted on the pipeline of different size and uses.

Fig. 2 is current floe condition side view of the present invention:
Fig. 3 is the present invention half open position side view.
Detailed description of the invention
From the embodiment of the present invention shown in Fig. 1-Fig. 3 it can be seen that valve body 1 is the shell of butterfly valve, for cylinder, the mouth of pipe has flange, bossed ring-type round platform in circle.Sliding sleeve 2 is the main body of Shell butterfly valve of the present invention, is also cylindrical, bossed ring-type limit on its cylindrical, and ring-type limit is outside one the mouth of pipe, and this mouth of pipe is fluid inlet, and cylindrical also has two symmetrical tooth bars and elongated hole, bossed ring-type round platform in circle.Valve plate 3 is circular plate type, has pedestal and the elongated hole with gap above.Gear 5, gear shaft 4 and driving axle 6 are cylinder.Equal sprocket drive spindle hole except gear shaft 4, driving axle 6 above, wherein the hole of sliding sleeve 2 is elongated hole.Sliding sleeve 2 has three Main Functions in Shell butterfly valve of the present invention, and one is that ring-type limit by it is squeezed in valve body 1 on circular round platform, it is achieved the sealing between sliding sleeve 2 and valve body 1.Two is that round inner annular round platform by sliding sleeve 2 is squeezed on the round edge of valve plate 3, it is achieved the sealing in sliding sleeve 2 pipe.Three is make valve plate 3 overturn by the driving axle 6 of fixed thereon.The effect of valve plate 3 is mainly closed conduct, stops fluid flowing.It is divided into the distance of straight elongated hole and plagioclase hole, its hole and gear shaft 4 and the length in each hole in the gap that on valve plate 3, pedestal is other, is related to the upset opportunity of valve plate, reversal rate, to prevent the edge of valve plate 3 from bumping against with circular round platform in sliding sleeve 2.First valve plate 3 is put into sliding sleeve 2 during installation, again driving axle 6 to be fixed on sliding sleeve 2, the axle body making driving axle 6 is placed in the gap of valve plate 3, again sliding sleeve 2 is placed in valve body 1, make the ring-type round platform plane in valve body 1 inner circle relative with the ring-type limit plane on sliding sleeve 2 cylindrical, then gear 5 is placed on by the tooth bar between valve body 1 and sliding sleeve 2, then with gear shaft 4 traverse from the axis hole of above each part, makes an entirety.The work of Shell butterfly valve of the present invention, is the rotation by gear shaft 4, makes the gear 5 band carry-over bar being fixed on gear shaft 4, makes sliding sleeve 2 move.When gear shaft 4 is to anticlockwise, sliding sleeve 2 moves to fluid inlet direction,
Sliding sleeve 2 one aspect of movement makes circular round platform in the sliding sleeve 2 cylindrical ring-type limit being squeezed on the interior circular round platform of valve body 1 and the sliding sleeve 2 being squeezed on valve plate 3 round edge depart from simultaneously: on the other hand, sliding sleeve 2 makes the valve plate 3 got lodged in sliding sleeve 2 pore overturn by the axle 6 that drives of fixed thereon, and fluid starts flowing with the upset of valve plate 3.When sliding sleeve 2 moves to the direction that fluid flows, the driving axle 6 on sliding sleeve 2 makes valve plate 3 overturn, and ring-type limit and ring-type round platform on sliding sleeve 2 are squeezed in again in valve body 1 on the round edge of circular round platform and valve plate 3 with the movement of sliding sleeve 2 simultaneously, prevent the flowing of fluid.So far, butterfly valve completes overall process that is through-flow and that dam.
Claims (1)
