INTEGRAL TYPE BALL VALVE, AND THREADLESS FITTING COUPLING BODY

摘要

PROBLEM TO BE SOLVED: To provide a ball valve provided with a threadless fitting to be connected to a pipe. SOLUTION: This integral type ball valve and a threadless fitting coupling body 10 are provided with a threadless fitting 18 in which both a male part and a female part formed as an integral structure coupled with the ball valve 30, and extended from at least one end wall 14 of a valve housing part 12 are assembled. The fitting includes a sleeve part 16 having a female type inner surface to receive a pipe 28, and a male type outer surface having at least two separate cylindrical parts. A driver member 38 having at least two separate cylindrical parts is also included. As the driver member is pushed lengthwise along the male type outer surface of the sleeve part, the cylindrical parts of the driver member are engaged with the male type outer surface of the sleeve part to deform the sleeve part. One pipe engaged in the sleeve part is also deformed this time. Gas-tight seal can thus be formed between the pipe and the female type inner surface of the fitting.
