Integral conical coupling band and rotary valve

The utility model relates to the technical field of valve devices, in particular to an integral conical coupling sleeve and a rotary valve, which comprise a coupling sleeve body and a clamping mechanism, and the coupling sleeve body is arranged in the clamping mechanism by arranging the clamping mechanism. A power medium is introduced into the clamping mechanism to enable the piston clamping seat to move downwards in the clamping seat mounting cavity, so that the outer wall of the upper middle part of the coupling sleeve body and the inner wall of the second clamping hole are matched, attached and connected together, and the coupling sleeve body is clamped, so that the clamping mechanism can provide larger and firmer clamping force; the possibility of fracture and looseness is reduced, the service life of the integral conical coupling sleeve and the 90-degree rotary valve is prolonged, and meanwhile the integral conical coupling sleeve is more convenient to install in a narrow space. 本实用新型涉及阀门装置技术领域，尤其涉及一种整体式
