Sealing device for one-section type high-pressure rubber membrane sealing type gas holder

Abstract

The invention discloses a sealing device for a one-section type high-pressure rubber membrane sealing type gas holder, and the sealing device is designed mainly for providing a one-section type gas holder sealing device which is high in safety and bearing capacity. The sealing device for one-section type high-pressure rubber membrane sealing type gas holder comprises a sealing rubber membrane, sealing angle iron, sealing box iron and a corrugated plate device; the corrugated plate device comprises corrugated plates, connecting pieces with clamping grooves, fastening pieces and connecting bolts; the sealing angle iron is connected to the a gas holder side plate, the sealing box iron is connected to a piston base plate, and the sealing rubber membrane is connected to the sealing angle iron and the sealing box iron; the corrugated plates are connected through the connecting bolts; the corrugated plates are connected through the connecting pieces and the fastening piece to form a barrel-shaped integral structure which is hung on multiple layers of angle iron rings located on the outer edge of a piston baffle through the clamping grooves in the connecting pieces, and the sealing rubber membrane is closely attached to the corrugated plates due to the pressure in work. The sealing device for one-section type high-pressure rubber membrane sealing type gas holder is high in bearing capacity and little in material consumption and repair and maintenance workload.

Description

technical field [0001] The invention relates to a one-stage high-pressure rubber membrane sealing type gas cabinet sealing device. Background technique [0002] One-stage rubber membrane sealed gas cabinet is a new type of gas cabinet that has appeared in China in the past two years. Its advantages such as low cost, stable pressure, stable operation, simple maintenance and neat and beautiful form are widely welcomed by users. The storage of blast furnace gas in one-stage rubber-membrane-sealed gas holders has also been gradually studied and implemented. Therefore, it is necessary to develop a sealing device for one-stage high-pressure rubber-membrane-sealed gas holders. [0003] The sealing of the traditional two-stage rubber membrane sealed gas cabinet is two sealing rubber membranes, two corrugated plates, the side plate of the cabinet body is connected with the sealing angle steel, and the sealing angle steel is connected with the T baffle bottom plate through the sealing...

AI Technical Summary

Problems solved by technology

This will cause the gap between the local corrugated plates to become larger, and the rubber film will be trapped in the gap between the corrugated plates by the gas pressure, which will damage the rubber film and cause gas leakage.

[0008] (2) In the traditional corrugated plate device, the corrugated plate is made of bent steel plate (such as figure 2 shown)

With the development of technology, the gas storage pressure of the rubber-membrane-sealed gas tank is increasing, and the moment of inertia and resistance moment of the bent steel plate are relatively small, so the span is small, and the number of layers of the angle steel ring needs to be set. There are also many connecting parts and fasteners, which will increase the material consumption and the workload of overhaul and maintenance

[0009] (3) The traditional corrugated plate device, because of its wide plate and thin corrugated plate, cannot weld stiffeners, and its bearing capacity is low. For high-pressure gas tanks, the method of increasing the thickness of the plate is generally adopted. To increase the bearing capacity, this method has low efficiency, high operating risk, and poor economic effect, and additionally increases the load of the angle steel ring on the outer edge of the piston baffle
