Technical Field

The utility model relates to a flange technical field especially relates to a quick sealing plugging device of flange mouth.

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.

After the flange and the pipeline in the prior art are installed, a gap exists at the joint of the flange and the pipeline, the sealing performance is poor, and the normal use of equipment is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a quick sealing and plugging device for a flange opening.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a flange opening rapid sealing and plugging device comprises a flange piece and a pipeline, wherein a first annular groove, a sliding hole, a limiting groove hole and a second annular groove which are communicated with each other are sequentially formed in the flange piece;

and the end surface of the pipeline is provided with a taper ring groove corresponding to the taper pressing plate.

Preferably, the outside cover of sealed depression bar is equipped with the spring, the both ends of spring respectively with the spacing face fixed connection of clamping ring and spacing slotted hole.

Preferably, the sealing pressure rod and the taper pressure plate are of an integrally formed structure.

Preferably, the pipeline is provided with the mounting panel of integrated into one piece structure on being close to the outer peripheral face of tip, seted up first mounting hole of assorted and second mounting hole on flange spare and the mounting panel respectively.

The utility model has the advantages that: compared with the prior art, the utility model has the advantages of simple structure and reasonable design, through the setting of clamping ring, tapering clamp plate, tapering annular and sealed pad isotructure, after two flange spare installations, the flange can compress tightly the clamping ring for inside the clamping ring embedding second annular groove, thereby make inside sealed depression bar slide, utilize the tapering clamp plate to compress tightly the part that fills up in being annular tapering annular, thereby close the gap between pipeline and the flange, promote sealing performance.

Drawings

Fig. 1 is a schematic view before installation of a rapid sealing and plugging device for a flange opening according to the present invention;

fig. 2 is a schematic diagram of the installed flange quick-sealing plugging device according to the present invention;

fig. 3 is the utility model provides a quick sealing plugging device's of flange mouth reference numeral A department enlargedly.

In the figure: the pipeline sealing device comprises a flange part 1, a pipeline 2, a taper ring groove 3, a sealing gasket 4, a first ring groove 5, a sealing pressure rod 6, a limiting groove hole 7, a second ring groove 8, a spring 9, a pressure ring 10, a taper pressure plate 11 and a sliding hole 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a quick sealing and plugging device for a flange opening comprises a flange piece 1 and a pipeline 2, wherein a first annular groove 5, a sliding hole 12, a limiting groove hole 7 and a second annular groove 8 which are communicated with each other are sequentially formed in the flange piece 1, a sealing pressure rod 6 is connected to the inside of the sliding hole 12 in a sliding manner, a taper pressure plate 11 is fixedly arranged at one end of the sealing pressure rod 6, a pressing ring 10 is welded at the other end of the sealing pressure rod 6, and a sealing gasket 4 is bonded on the upper surface of the flange piece 1 through an adhesive; the end surface of the pipeline 2 is provided with a taper ring groove 3 corresponding to the taper pressing plate 11.

Wherein, through the setting of clamping ring 10, tapering clamp plate 11, tapering annular 3 and sealed 4 isotructures of filling up, after 1 installations of two flange spare, the flange can compress tightly clamping ring 10 for inside clamping ring 10 embedding second annular 8, thereby make inside sealed depression bar 6 slide, utilize tapering clamp plate 11 to compress tightly the part that fills up 4 with sealed in being annular tapering annular 3, thereby close the gap between pipeline 2 and the flange, promote sealing performance.

The outside cover of sealed depression bar 6 is equipped with spring 9, and the both ends of spring 9 respectively with the spacing face fixed connection of clamping ring 10 and spacing slotted hole 7, sealed depression bar 6 and tapering clamp plate 11 be the integrated into one piece structure, are provided with the mounting panel of integrated into one piece structure on the outer peripheral face that pipeline 2 is close to the tip, have seted up first mounting hole of assorted and second mounting hole on flange spare 1 and the mounting panel respectively.

In this embodiment, during installation, pass through the bolt with flange and pipeline 2, bolt fixed connection, later with two flange spare 1 fixed connection together, flange spare 1 is after fixed, extrude clamping ring 10 that the end set up mutually, thereby make sealing depression bar 6 slide, the annular tapering clamp plate 11 that is of sealing depression bar 6 end fixed connection then can extrude the part of sealed 4 of filling up and imbed in tapering annular groove 3, because sealed 4 have the annular part of being tightly to be pressed down in tapering annular groove 3, so the gap closure between pipeline 2 and the flange spare 1, thereby promote sealing performance, ensure the normal use of equipment.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
