Description
Technical field
The present invention relates to a kind of Pressure Container, relate in particular to a kind of quick-opening device for withstanding pressure container.
Background technique
The object of handling in the Pressure Container is solid in this way, and volume is bigger, and the aperture of door of large-size must be arranged on this container, so that the solid of these large volumes can freely be put into or take out, the aperture of door of large-size must definitely compress, so that container inner pressure can keep for a long time during the Pressure Container pressurized.The most ancient the most conservative method, the flange of aperture of door tightens up with the inspection of the manual spiral shell of some, as long as the pressurized container requirement is satisfied in flange arrangement, material, size and bolt quantity, material, size strictness, this aperture of door must be safe and reliable just.Though the aperture of door of this manual mounting or dismounting is reliable, as frequent operation, then very trouble and fatigue, then various quick-opening devices appear on the industrial production, so that mounting or dismounting can be quick and convenient.
On the industrial production several quick opening structures have appearred both at home and abroad.Be " the cap-rotating type quick operating valve " that compresses in the middle of a kind of door closure the earliest.This quick operating valve is applicable to the container that aperture of door is less.Occurred the application of force in the middle of a kind of door closure afterwards, adopted self-styled " C " shape flange seal circle, adopted the quick operating valve of cylinder and single gib head keying, and can be used for diameter and reach door closure about 1 meter.This quick operating valve only compresses hook with one, and compressing hook has to compress an inclined-plane, and as misoperation, it is often automatically-unhooked to compress hook, and this kind quick operating valve is very unreliable.The a plurality of hook quick operating valves that compress of development on this single quick operating valve basis that compresses hook, this many hooks quick operating valve obviously increases than single hook reliability, and the quick operating valve diameter can be above 1 meter, reached about 1.5 meters, but structure is quite complicated, as misoperation, the automatically-unhooked phenomenon of gib head can take place still.Also having has up and down two semicircle compaction hoops on inclined-plane will go up the quick operating valve that lower flange compresses in a kind of the utilization.This quick operating valve is difficult for opening voluntarily, and is more reliable than single hook, but this quick operating valve size is difficult to do greatly, if the aperture of door diameter above 1 meter, the semicircle compaction hoop is difficult to make lower flange to reach reliable sealing.Use the most generally " side set shape quick operating valve " on the industrial production both at home and abroad at present." side set shape quick operating valve " has two classes, and a class does not have the rotating clamp lock ring, relies on quick operating valve self rotation; Another kind of is that container upper flange and door closure upper flange do not change, and only relies on rotating clamp lock ring supported flange.The sealing reliability of " side set shape quick operating valve " is all higher than other various quick operating valves, and therefore domestic and international many pressurized containers (as disinfection tank, sulfurizing pot, extractor, filter equal pressure container) are used a lot.It is very accurate that the matching requirements of " but side set shape quick operating valve " cooperates, and machining requires very high.The aperture of door maximum diameter can only be accomplished 1.2 meters at present, and bigger diameter is just quite difficult.All seal faces of this device are very near from the aperture of door edge on the other hand, if solid is corrosive in the container, when opening quick operating valve, take out solid objects, because seal face is very near apart from the aperture of door edge, solid in the container, especially the sizable powdery solid of volume manually takes out from container or takes out automatically, the corrosivity material is easy to corrode the Sealing of side set, makes the very fast inefficacy of these crucial parts and can't use the sealed member that must more renew immediately.Because compaction hoop is a single piece, changes this parts, bother very much, cost is very high, and this problem has also limited side set shape structure and has been extensive use of.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the quick-opening device for withstanding pressure container of a kind of simple in structure, reliable performance, convenient operating maintenance, long service life is provided.
To achieve these goals, technical solution of the present invention is such: quick-opening device for withstanding pressure container, the fixing bolt positioning block of some on the circumferential surface of vessel flange, the vessel flange axial restraint is provided with bolt in bolt positioning block upper edge, be provided with in the bolt bottom movable cooperate rotatably compress piece and setscrew nut, the inner end that rotatably compresses piece compresses the quick operating valve flange, fixedly connected with the rotation support arm in the outer end that rotatably compresses piece, the seal face of described inner end that rotatably compresses piece and quick operating valve flange along the quick operating valve flange circumferentially be on the rotation support arm, be provided with the power opening and closing device that the rotary driving compact heap rotates in the inclined-plane.
The invention has the beneficial effects as follows: because the present invention has adopted a plurality of pieces that rotatably compress that the flange of quick operating valve is compressed, and operate on it with the power opening and closing device, thereby have that boundary dimension simple in structure, quick operating valve is unrestricted, the advantage of reliable performance, convenient operating maintenance, long service life.
