Problems solved by technology

The plugging device with this structure is simple in structure and easy to use, but because the two sealing rings and hinges it uses are all hard materials, and there is no corresponding seal at the leakage point (leakage), making the plugging The contact surface between the device and the leakage point does not fit, and the seal is not tight, which has caused secondary leakage

Embodiment Construction

[0019] The present invention will be further explained below in conjunction with specific embodiments and accompanying drawings, but it is not intended to limit the present invention.

[0020] like figure 1 , figure 2 As shown in the figure, a device for quickly plugging a leak point of a pipeline includes an occluder 3 acting on the leak point of the pipeline and a fastener for fixing the occluder 3, and the fastener is specifically a bolt 5 and a connection with the bolt 5. When installing the matching nut 5-1, in order to prevent the friction between the bolt 5 and the nut 5-1 to the pipe 1, a lining can be laid on the contact surface of the bolt 5, the nut 5-1 and the pipe 1. Pad 6.

[0021] like image 3 , Figure 4 As shown, the occluder 3 is mainly composed of a sealing gasket 3-1 and a waterproof diaphragm 3-2 in sequence from the inside to the outside, and a conical plug 7 is provided at the center of the surface of the sealing gasket 3-1. In order to further im...

Abstract

The invention discloses a quick plugging device for pipeline leaking points. The quick plugging device comprises a stopper acting on the pipeline leaking points and fasteners used for fixing the stopper. The stopper is mainly formed by sequentially bonding and compounding a sealing gasket and a waterproof diaphragm form inside to outside. A tapered plug is arranged at the center of the surface of the sealing gasket. The two symmetrical side edges of the stopper are provided with jackets correspondingly, and the jackets and the stopper are integrally formed. Jacket holes are formed in the surface of each jacket. The fasteners are connected with the jacket holes in the stopper through connecting ropes. By the adoption of the stopper, the tapered plug on the stopper, the connecting ropes and the fasteners, the pipeline leaking points can be plugged quickly, the contact surfaces of the stopper and pipelines are tightly attached, and the plugging effect is good. The quick plugging device has the characteristics of being simple in structure, tight in plugging and convenient to operate, thereby being suitable for plugging various sorts of pipeline leaking points.

Description

technical field [0001] The invention relates to a plugging device, in particular to a device for quickly plugging a leak point of a pipeline, and belongs to the technical field of pipeline maintenance equipment. Background technique [0002] Pipeline is a common transmission equipment, and it is an indispensable component in the fields of oil, natural gas, water and other systems. At present, the pipes on the market are generally divided into PE plastic pipes and corrosion-resistant metal pipes, and targeted selections are made according to different transmission substances. But no matter what kind of material the pipeline is, as the use time increases, the pipeline will inevitably crack due to corrosion, aging and other reasons, resulting in pipeline leakage. Especially in the high-pressure pipelines of flammable and explosive substances such as oil and natural gas, once leakage occurs, it is likely to cause safety accidents such as fire and explosion, which will seriously...
