Clutch type plugging valve

The invention discloses a clutch type plugging valve. The clutch type plugging valve comprises end pipes, the inner ends of the end pipes are symmetrically connected to the two ends of a pipe sleeve in a sleeved mode, inner pipes are sleeved with inner end holes of the end pipes through sliding ways, the inner ends of the inner pipes are integrally connected with one ends of guide rods, the otherends of the inner pipes are inserted into guide holes formed in the pipe sleeve, the guide holes are further filled with springs, the outer ends of the guide holes are blocked and connected through countersunk bolts, baffle rings are connected to the inner walls of the inner pipes, sealing gaskets are clamped to inner holes of the baffle rings, hemispheres are symmetrically arranged in the pipe sleeve, the hemispheres are connected through a piston structure, elliptic cylinders are symmetrically arranged between the hemispheres, and the outer ends of the elliptic cylinders are connected with arotating rod in a penetra
