| 摘要 |
The invention concerns a valve operator assembly (1) for valve (2). The valve (2) comprises a valve body (3) and a valve translating member (4) axially moveable. The valve operator assembly (1) comprises a housing (5) adapted to be mounted on the said valve (2), an input member (6) rotatably mounted with respect to said housing (5), and a transmission mechanism (7). Said transmission mechanism (7) comprises a translating element (8) adapted to be connected to the valve translating member (4) and a rotating element (9) connected to the input member (6), said transmission mechanism (7) being adapted to convert applied rotation of the input member (6) into axial translation of said translating element (8). The valve operator assembly (1) further comprises a spacing element (17) adapted to be connected on the valve body (3) on one end and on the housing (5) on the other end, the said spacing element (17) having an almost tubular shape defining an axial bore through which passes at least partly the valve translating member (4) and the translating element (8) of the transmission mechanism (7). |
