摘要 |
Apparatus for radiator valve servicing has a main body 1 including a valve 5 and an adaptor 2 connecting the main body to a valve assembly support body 102. Mounted for movement within the main body is an extractor 3 comprising a shaft 30 and coupler 31 which is connected by a bayonet fitting 39,40 to the shaft and mechanically connected by a screw 37 to the valve assembly spindle 103. The coupler includes a socket 33 which fits on and facilitates unscrewing of the spindle and valve assembly from the support body. After being unscrewed, the valve assembly can be lifted past the valve 5 and, after closing the valve, withdrawn reliably from the main body because of the screw connection for servicing. A selection of adaptors and couplers enable a range of different valve systems to be serviced without draindown. <IMAGE> |
