Description
Technical Field
The utility model belongs to the technical field of the pipeline shutoff technique and specifically relates to an elasticity skeleton type pipeline plugging device.
Background
In the prior art, the pipeline plugging device basically adopts the compression of the distance between an upper pressure plate and a lower pressure plate to deform a sealing rubber sleeve positioned between the upper pressure plate and the lower pressure plate, so that the middle part of the sealing rubber sleeve protrudes outwards, thereby plugging the pipeline. And in order to ensure that certain pressure is required between the deformed sealing rubber sleeve and the inner wall of the pipeline, the thickness of the sealing rubber sleeve is larger, so that the force generated by deformation is larger, and the sealing property can be better maintained. But this increases the cost of the product.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned technique not enough and provide an elasticity skeleton type pipeline plugging device, can utilize the elastic support board to produce bearing pressure to the sealing rubber cover, ensure sealing performance.
The utility model discloses an elastic skeleton type pipeline plugging device, including top board, holding down plate and sealing rubber sleeve, be provided with a through-hole in top board center department, be provided with a bolt in the through-hole, be provided with a connecting cylinder in holding down plate center department, and the inside internal thread that is provided with of connecting cylinder, the bolt passes behind the through-hole and is connected with the interior screw-thread fit of connecting cylinder, is provided with the elastic support board of loop configuration between top board and holding down plate, sets up at the outside cladding of elastic support board sealing rubber sleeve.
Above-mentioned technical scheme is provided with the elastic support board between top board, the holding down plate, and the sealing rubber cover cladding is outside at the elastic support board, so rotate through the bolt and make the top board, the interval between the holding down plate reduces and extrudees elastic support board and sealing rubber cover, makes it outside protruding, protruding in-process, elastic support board has good holding power, so at the sealed in-process of pipeline, the sealing rubber cover is used in the pressure stability of pipeline inner wall, and its long-time back pressure that uses can not decline, and sealing stability is high. In addition, the pressure required by the pipeline sealing can be provided by the elastic supporting plate, so that the thickness of the sealing rubber sleeve can be obviously reduced, and the production cost is greatly reduced.
The upper pressing plate and the lower pressing plate which correspond to the two ends of the elastic supporting plate are respectively provided with an annular groove, the upper end and the lower end of the sealing rubber sleeve are folded inwards and then wrapped at the two ends of the elastic supporting plate, and the end parts of the elastic supporting plate and the sealing rubber sleeve are clamped in the annular grooves. The design of this structure, the equipment and the connection to pipeline plugging device that can be more quick, further reduce cost.
A plurality of hollow structures are arranged on the circumferential side wall of the elastic supporting plate at intervals, and the hollow structures are in the shapes of: the width of the strip-shaped structure is gradually reduced from two ends to the middle. The design of this structure, when the extrusion is received at its both ends, can be outside protruding to change the external diameter of elastic support board, realize the support to the sealing rubber cover, ensure its outside protruding back and pipeline's sealing performance's stability.
The outer surface of the sealing rubber sleeve is provided with a plurality of annular bulges along the circumferential direction. The design of the annular bulge can further improve the sealing of the pipeline plugging device to the pipeline in the using process.
The utility model provides an elasticity skeleton type pipeline plugging device, its design through elasticity skeleton utilizes the deformation of elastic support board to make the sealing rubber cover enlarge, realizes sealed to the shutoff of pipeline, and the leakproofness is good, and is with low costs.
