Description
Technical Field
The utility model relates to a flange seal technical field, concretely relates to sealing device is pressed in flange root area.
Background
A flange, also known as a flange collar or flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange. The flanges are used in pairs, the low-pressure pipeline can be screwed with the flanges, and the flanges are welded under the pressure of more than four kilograms. And a sealing gasket is arranged between the two flanges and then is fastened by bolts. The flanges of different pressures have different thicknesses and they use different bolts. When the water pump and the valve are connected with a pipeline, the parts of the equipment and equipment are also made into corresponding flange shapes, which are also called flange connection. The connecting parts which are connected by using bolts at the peripheries of two planes and are closed at the same time are generally called flanges, and for example, the connecting parts of the ventilating duct can be called flange parts. The pipe flanges are classified into the following six basic types according to the connection mode with the pipe: a flat welding flange, a butt welding flange, a socket welding flange, a loose sleeve flange, a threaded flange and an integral flange.
The root of the pipeline flange can leak due to welding, vibration, expansion with heat and contraction with cold and the like, the original sealing method is stopped production, and then repair welding is carried out, so that the loss caused by the method is large, the production stop time is long, a large amount of time can be wasted, the working efficiency is low, and the production cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect with not enough, provide a sealing device is pressed to flange root, it need not stop production, does not need repair welding, can practice thrift a large amount of time, does not have any loss, can not influence production, low in production cost, work efficiency is high.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the leakage-stopping sealing device comprises a pipeline 1, fixtures 2, glue-injecting holes 3, leakage-stopping sealing glue 4 and a flange inner ring 5, wherein the fixtures 2 are arranged on the upper side and the lower side of the pipeline 1, the fixtures 2 on the two sides are of an up-and-down symmetrical structure, the fixtures 2 and the pipeline 1 form a closed structure, the leakage-stopping sealing glue 4 is arranged on the closed structure, the glue-injecting holes 3 are formed in the leakage-stopping sealing glue 4, the fixtures 2 are fixed at the root of the flange, the flange comprises the flange inner ring 5 and the flange outer ring 6, and the flange outer ring 6 is arranged on the outer side.
