Description
Technical field
The present invention relates to a kind of air flume revolution shutoff valve, belong to shutoff valve class field.
Background technology
Air conveyer flume is the continous way pneumatic transport equipment for being tilted to lower conveying dry powdery material.During convey materials, material, by high-end feeding upper shell, is blown into air by blowing engine to lower house simultaneously.The chien shih material that air is distributed in material particles by the air-permeable layer of the hole that gathers is fluidized.Because cell body has downward gradient, the material of fluidization under gravity just along cell body forward slip, reaches conveying object.Air flume conveying often forms a lot of branch road, and this just needs the groove for turning to and the shutoff valve for opening and closing.Traditional shutoff valve is paddle type structure, pull flashboard to control the open and close of air flume up and down, but this structure is for the due effect of large-scale air skewed slot (more than 800 types) out of reach primarily of cylinder.Large-scale skewed slot due to sectional area large, it is very large that this just requires flashboard also to do, and flashboard is too large, is easily out of shape on the one hand, increases deadweight on the other hand, needs larger hoisting force.Large-scale skewed slot height increases, and flow is also comparatively large, and flashboard type structure often leak tightness is not fine, and open and close is also dumb.
Summary of the invention
The object of this invention is to provide a kind of air flume revolution shutoff valve, solve large-scale air skewed slot (more than 800 types) flashboard type shutoff valve flashboard too large, impact resistance is little, holds yielding problem.
For achieving the above object, the technical solution adopted in the utility model is:
Air flume revolution shutoff valve, comprise the housing of access air flume, described enclosure interior is divided into the sprue on top and the air flue of bottom, and be air-permeable layer between sprue and air flue, the two ends of air flue are airtight, gives a dinner for a visitor from afar machine air extractor duct in the lower end of air flue;
Fan-shaped cylindrical spool is established in sprue, the protrusion direction of the arc of spool is feed end, the arc center shaft horizontal positioned of spool also arranges axis of revolution at cental axial position, axis of revolution is fixed on valve housing two side by support sleeve and housing is stretched out in one end, axis of revolution exposes housing parts and connects rotary motive power system, sealing band is established in both sides and the top of spool arc, and the arc motion path end of spool is baffled near air-permeable layer place.
As preferably, described rotary motive power system comprises fork and cylinder, and the fixed end of axis of revolution and fork is fixed, and the fork other end connects the axis of the piston of cylinder, and cylinder connects source of the gas.
As preferably, described air-permeable layer is that syntheticfibres forms through integral weaving.
As preferably, described spool is that arc and multiple quadrant combine, and the arc-shaped side of quadrant and the inner concave of arc fix, and axis of revolution establishes support sleeve to be fixedly connected with the cental axial position of described quadrant.
The advantage of this patent: 1, open and close flexibly, rotary structure rotates flexibly, and required drive is little; 2, curved-surface structure impact resistance is strong, not yielding; 3, compact conformation, is convenient to install, good airproof performance; 4, air operated control opens and closes, and can realize Long-distance Control by electromagnetic valve.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described
The present invention as Fig. 1-4, shown in, air flume revolution cut-off valve housing is rectangular structure, and inside is divided into sprue 1 and air flue 2, is Flow of Goods and Materials in sprue 1; Pass into air by blower fan in air flue 2, air flue 2 two ends seal; Split by the air-permeable layer 3 of the hole that gathers between sprue 1 and air flue 2, air-permeable layer 3 adopts high-quality synthetic fiber material to become through integral weaving.
Air flue 2 is provided with the ventilation inlet 4 communicated with blower conduits, and the flange at housing 14 two ends is connected with the casing flange of air flume.Spool 5 is in sprue 1, and spool 5 is made up of arc 6 and multiple quadrant, support sleeve 7, axis of revolution 8.
Arc 6 is the curved-surface structure of high-strength abrasion-proof plate use new process bending.Quadrant 15 is the fan-shaped high-strength abrasion-proof plates become according to the surface incising of arc 6.Quadrant 15 and arc 6 are fixed on axis of revolution 8 by support sleeve 7, and axis of revolution two ends are supported by bearing seat 9, and the engine installation that spool 5 rotates is cylinder 10, and axis of revolution 8 one end connects cylinder by fork 11, and cylinder piston shaft extension goes out, and spool 5 is closed; Cylinder piston is retracted, and spool 5 is opened.Upper, left and right three faces of spool 5 have sealing band 12 to seal, and when spool 5 is closed, arc 6 edge of spool 5 contacts with the baffle plate 14 of air-permeable layer 3, are sealed completely by sprue under ensureing spool 5 closed condition.
When cylinder piston is retracted, spool 5 rotates to be opened, and the sprue entering housing as Fig. 2 material is inner, air flue 2 passes into air by blower fan, air flue two ends seal, and can ensure that material blows afloat by air permeable air-permeable layer 3, enter next joint equipment in fluidised material by Action of Gravity Field.Cylinder piston stretches out, spool 5 rotary closing, and as Fig. 3, material can effectively end by spool 5 structure, and the spool of curved surface can bear larger material impact, and wear plate is particularly suitable for being applied in chiseling property of mill material.
Quadrant 2-3 supporting arc 6.The cylinder of engine installation is furnished with solenoid control.
