Embodiment 1

[0019] Such as figure 1 Described in: the pipe plugging device has a pipe plugging through cover 7 with a rectangular thread, and a valve 10 with the function of guiding water is connected to the outer end of the pipe plugging through cover 7. Open it for pressure relief; when blocking, screw the plug-through cover 7 with the diversion valve and the rubber sealing connection sleeve 3 together through a rectangular thread, and then cover the end of the leaking pipeline as a whole. The outlet pipe hoop is locked on the rubber sealing connecting sleeve 3, and the pipe hoop is locked with a special tool. The contact surface between the rubber sealing connecting sleeve 3 and the leaking pipe is a zigzag ring seal, and it can generate greater friction with the pipe wall If the leakage pressure of the pipeline is high, the internal fastening screw 6 can be used to connect the pull plate 1 and the pipe plugging cover 7 after the pipe clamp is locked; finally, the diversion valve 10 is...

Embodiment 2

[0021] The quick pipe plugging device can be directly applied to the leakage of the pipe port. When the leak occurs at the broken port of the pipe, it can be quickly blocked by putting it on the port of the pipe according to the above steps; After the pipe is cut, the device is set on the fracture and locked with a pipe clamp to quickly block and divert the flow.

Abstract

The invention discloses a device for emergently plugging a risk source pipe orifice and a rapid plugging method thereof. In the device, a serrate sealed pipe clamp is arranged at one end of a reducing rubber seal connection sleeve, the other end is provided with external threads which correspond to a pipe-plug transparent cover with inner threads; the end head of the pipe-plug transparent cover is provided with a diverter valve and communicated with the reducing rubber seal connection sleeve, and the other end head is an outer edge; a threaded hole is formed on the outer edge; and the end head of the serrate sealed pipe clamp is provided with a connection pulling board connected with the threaded hole on the outer edge of the pipe-plug transparent cover. The method comprises the followingsteps: the pipe-plug transparent cover is screwed together with the rubber connection sleeve; the rubber seal connection sleeve is locked on a pipeline by using a pipe clamp after the diverter valve is opened for decompression, and the connection pulling board and the pipe-plug transparent cover are tightened by bolts; and then the diverter valve is closed to achieve the emergent plugging of the risk source pipe orifice. The invention has simple structure, convenient operation, rapid plugging speed and low cost, is suitable for production and transportation of petrochemical industry and coal chemical industry, and is also used for the rapid plugging of gas, heat and water supply and wrecking pipelines.

Description

technical field [0001] The invention relates to a pipeline port sealing device and its sealing method, in particular to an emergency sealing device and its rapid sealing method for the fracture of a risk source pipeline, such as petrochemical, coal chemical production and toxic gas-liquid storage. Transportation equipment pipelines and emergency sealing devices and quick sealing methods for gas, heat and water supply emergency pipelines. Background technique [0002] According to statistics, there are about 4 billion tons of dangerous substances in the production of chemicals every year. These substances have huge potential dangers in the process of production and transportation. Once an accident occurs, it will cause serious consequences. [0003] In recent years, there have been many leakage accidents in my country. On July 7, 2000, a major poisonous gas leakage accident occurred in Chengdu-Chongqing Expressway. Due to the failure to use a suitable sealing method, a large ...
