Zusammenfassung:	The utility model discloses a valve feedback connecting device. The motor comprises a movable iron core and a coil. The iron core freely slides in the coil; wherein the coil is fixed in a fixed shell;the displacement of the valve is measured through up-and-down sliding of the iron core; one end of the movable iron core is connected with one end of the flexible connecting device through a bolt, the other end of the flexible connecting device is in rigid connection with the valve feedback plate, the flexible connecting device is composed of an inner-layer structure and an outer-layer structure,the inner-layer structure is made of high-temperature-resistant rubber materials, and the outer-layer structure is a stainless steel corrugated hose. The linear variable differential transformer hasthe advantages that after the flexible connecting device is additionally arranged on the movable coil, friction between the movable coil and the static coil of the linear variable differential transformer is effectively avoided
