Pipeline interception device and auxiliary construction equipment thereof
This invention discloses a pipeline shut-off device and its auxiliary construction equipment, relating to the field of pipeline shut-off technology. It includes a steel ring and a sealing ring installed on the inner circumference of the steel ring. The outer circumference of the steel ring is used to contact the inner wall of the pipeline. Multiple sealing strips are arranged in a circular array on the inner circumference of the sealing ring, with baffles between adjacent sealing strips. Multiple baffles and sealing strips are spliced together to form an insertion hole coaxial with the steel ring. It also includes a clamping rod. The steel ring and sealing ring combine to form a rigid structure. After the clamping rod is inserted, it expands the multiple baffles and sealing strips, achieving a tight fit between the sealing strips and the steel ring through mechanical expansion. The steel ring also deforms slightly to press against the inner wall of the pipeline. This replaces the traditional airbag-based sealing method that relies on air pressure, fundamentally avoiding the sealing failure problem caused by pressure fluctuations, punctures by sharp objects on the pipe wall, or air leakage. Furthermore, it eliminates the need for auxiliary equipment such as air compressors, making operation simpler.
