A pressurized plugging fixture

Abstract

The invention discloses a leaking stoppage clamp under pressure. The leaking stoppage clamp under pressure is used for stopping a leaking point at the joint of two pipelines. The leaking stoppage clamp under pressure comprises four clamp blocks. Each clamp block is provided with a semicircular hook face and a semicircular sealing face. The hook face of the first clamp block and the hook face of the second clamp block form a first circular hook face capable of surrounding the outer wall of the first pipeline, the sealing face of the first clamp block and the sealing face of the second clamp block form a first circular sealing face, the hook face of the third clamp block and the hook face of the fourth clamp block form a second circular hook face capable of surrounding the outer wall of the second pipeline, the sealing face of the third clamp block and the sealing face of the fourth clamp block can form a second circular sealing face, a glue injection cavity is jointly defined by the first circular hook face and the second circular hook face, and the four clamp blocks are each provided with a glue injection through hole communicating with the glue injection cavity. The leaking stoppage clamp is applicable to carrying out leaking stoppage on the joint of the pipelines or the position nearby the joint.

Description

technical field [0001] The invention relates to the field of pressure pipelines. Specifically, it is a leak plugging clamp under pressure. Background technique [0002] The use of pipelines to transport gas or liquid has been widely used in various industries. The gas or liquid in the pipeline has a high pressure. When there is a leak in the pipeline, the gas and liquid will leak under the action of pressure, especially in Where two pipes connect, leakage is more likely to occur. If the medium is dangerous liquid or gas, it will not only cause environmental pollution, but also bring great safety hazards to production, and enterprises are often forced to stop production, resulting in economic losses. In order not to affect the transmission of the medium, it is necessary to carry out plugging under pressure. For pipelines with relatively high pressure, it is necessary to use clamps to form a sealed cavity at the leak point, and fill the cavity with sealant to block the leak...
