Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 As shown, the pipeline pressure sealing device of the present invention includes a rubber plate 2, an outer steel clamp 3, and a valve 4; the outer steel clamp 3 includes two semicircular steel clamps on the left and right, and the middle part of the right steel clamp is drilled with a hole. The outer diameter of the right steel clamp is welded with a common wire head to install the valve 4 at the corresponding hole. When the outer steel clamp 3 is connected and fastened, a rubber plate 2 is lined on its inner wall.

[0013] When sealing the leak point of pipeline 1, first open the valve 4 on the right steel clamp, then align the holes on the right steel clamp and rubber plate 2 with the leak point of pipeline 1, and then press the left steel clamp on the pipeline 1, use bolts 5 to connect and fix the two halves of th...

Abstract

The invention belongs to the technical field of pressure plugging of pipelines, in particular to a pressure plugging device for a pipeline. The pressure plugging device comprises a rubber plate, an outer steel clip and a valve; the outer steel clip comprises a left semicircular steel clip and a right semicircular steel clip; a hole is drilled in the middle part of the right steel clip; a wire endis welded to a position, corresponding to the hole, on the external diameter of the right steel clip, and is provided with the valve; when the outer steel clip is connected to perform fastening, the inner wall of the outer steel clip is lined with a ring of rubber plate; a hole is formed in the middle part of the rubber plate; and the rubber plate wraps the pipeline. When the leakage point of thepipeline is plugged, the valve on the right steel clip is opened firstly; then, the hole in the right steel clip and the hole in the rubber plate are aligned with the position of the leakage point ofthe pipeline; then, the left steel clip is pressed on the pipeline; the outer steel clip in half is connected and fixed firmly with bolts; and the valve is closed, so that the leakage point of the pipeline is rapidly plugged. The pressure plugging device is capable of rapidly handling the leakage problem of the pipeline, and is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of pipeline pressure sealing, and in particular relates to a pipeline pressure sealing device. Background technique [0002] When dealing with pipeline leaks, ordinary rubber sheets are used to wrap the pipeline, and then ordinary iron wires are used to bind the pipeline. This method can only solve the problem of temporary pipeline leakage, has poor reliability, and is prone to the risk of secondary leakage. Contents of the invention [0003] The purpose of the present invention is to provide a pipeline pressure sealing device with simple operation, which can quickly deal with the pipeline leakage problem, and is safe and reliable. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A pipeline sealing device under pressure, including a rubber plate, an outer steel clamp and a valve; the outer steel clamp includes two semicircular steel clamps o...
