FIELD: pipeline reinforcement.
SUBSTANCE: device for quick switch of a plug comprises a sealing structure, a clamping structure, a supporting structure, and an actuating mechanism. The plug has an open state and a closed state. The supporting structure is made with the possibility of connecting pipelines on both sides and ensuring the support of the entire device. The clamping structure and the sealing structure are located inside the supporting structure. The clamping structure is actuated by means of an actuating mechanism, and when actuated, the clamping structure clamps the plug to eliminate the gap between the two sides of the plug, ensuring the formation of a seal by means of the sealing structure. When the gap is formed at a distance from the plug, it switches between the open state and the closed state.
EFFECT: invention is aimed at accelerating the switching of the plug and increasing the reliability of its insulation.
