Description

High-temperature feeding Wear-resisting rotating valve
Technical field
This utility model one high-temperature feeding Wear-resisting rotating valve, for controlling the rotary valve of solid material stream switching, is widely used in conveying quartz sand, pulverized limestone, cement, flyash, aluminium oxide etc..Belong to the technical field of valve manufacture.
Background technology
The most conventional rotary valve mainly has ball valve and spherical valve, ball valve is mainly made up of the axle being sealed in cast iron or steel shell with material flow passage, charging aperture is arranged at the top of shell, discharging opening is arranged at bottom, and axle rotates under the effect of drive mechanism in certain angle the break-make control realizing stream.Spherical valve is mainly made up of cast iron or steel shell, spool and drive mechanism, and spool is made up of the ribs of spherical seal surface, axle and connecting shaft with spherical seal surface.Spool rotates the break-make control realizing stream under the effect of drive mechanism in certain angle.These two kinds of valves are easily stuck by material when controlling the solid material of hardness chiseling property of mill bigger, medium, and fault rate is high;When being particularly full of solid material in valve body, valve is opened, closing process, and sealing surface wear is serious, and in closing process, valve sealing surface is during housing, and shearing force is gradually increased, and for overcoming shearing force, the power consumption of drive mechanism is big;Longtime running sealing surface wear is serious, and air-tightness can not be guaranteed, and service life is short;If sealing surface takes wear-resistant process, then cost is high.
Utility model content
Technical problem to be solved in the utility model is to provide for above-mentioned prior art that a kind of air-tightness is good, power consumption is few, the high-temperature feeding Wear-resisting rotating valve of not shearing-crushing material, length in service life.
The technical scheme in the invention for solving the above technical problem is: a kind of high-temperature feeding Wear-resisting rotating valve, it mainly includes valve body and cylinder, the cylinder body of described cylinder is fixed on valve body, described valve body offers charging aperture and discharging opening, described valve body is provided with rotary shaft, it is connected by bearing between rotary shaft with valve body, and the axial line of rotary shaft and charging aperture is parallel to each other, one end that described rotary shaft is positioned at outside valve body is connected with the outfan of cylinder by the first connector, it is positioned on one end of valve body and is provided with the second connector, described second connector is provided with rotary valve plate.
Preferably, sealed by wolfram steel circle between described rotary valve plate and charging aperture.
Compared with prior art, the utility model has the advantage of:
This utility model drives valve plate to move by rotary shaft so that motion during valve switch action is rotary motion.The piston rod of pneumatic actuator not with physical contact between media, extend the service life of actuator.Sealing pair uses the high-abrasive materials such as hard wolfram steel, pottery, has longer service life.Using temperature 250-600, performing cylinder nominal pressure pressure is 0.4-0.6Mpa.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Valve body 1, discharging opening 1.1, charging aperture 1.2, discharge chamber 1.3, cylinder 2, rotary shaft the 3, first connector the 4, second connector 5, rotary valve plate 6, wolfram steel circle 7.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
nullAs shown in Figure 1,A kind of high-temperature feeding Wear-resisting rotating valve in the present embodiment,Mainly include valve body 1 and cylinder 2,The cylinder body of described cylinder 2 is fixed on valve body 1,Described valve body 1 offers charging aperture 1.1 and discharging opening 1.2,It is discharge chamber 1.3 between described discharging opening 1.1 and charging aperture 1.2,Described valve body 1 is provided with rotary shaft 3,It is connected by bearing between rotary shaft 3 with valve body 1,And the axial line of rotary shaft 3 and charging aperture 1.1 is parallel to each other,One end of described rotary shaft 3 is positioned at outside valve body 1,The other end is positioned at valve body 1,The one end being positioned at outside valve body 1 is connected with the outfan of cylinder 2 by the first connector 4,It is positioned on one end of valve body 1 and is provided with the second connector 5,Described second connector 5 is provided with rotary valve plate 6,Sealed by wolfram steel circle 7 between described rotary valve plate 6 and charging aperture 1.1.
During work, cylinder is rotated axle by the first connector and rotates, and rotary shaft acts on the second connector, and the second connector is rotated valve plate and rotates so that motion during valve switch action is rotary motion.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
