US 2010/0140522 A1 · Separable Ball Valve Apparatus and Ball Valve Assembly

Abstract

A separable ball valve apparatus and ball valve assembly capable of selectively opening/closing a separable flow path are provided. The separable ball valve apparatus comprises a separable pipe member having a flow path through which fluid flows, a ball member having at least two balls disposed in the pipe member, opening and closing the flow path, and adjacent to each other, and an opening/closing member configured to control the ball member to open/close the flow path, wherein the balls have through-holes, respectively, and the opening/closing member includes a gear train configured to control the opening/closing of the at least two balls. Therefore, it is possible to simply open/close pipes having the flow path and detachably attach the pipes, increase space utilization due to removal of a separate coupling space for attachment/detachment of the pipes, and simultaneously open/close the two pipes, which are separated from each other through one operation.

A separable ball valve apparatus, comprising:

a first pipe having a first flow path through which fluid flows;
a second pipe having a second flow path connected to the first flow path and detachably coupled to the first pipe;
a first ball disposed in the first pipe, configured to open/close the first flow path, and having a first through-hole;
a second ball in contact with the first ball, disposed in the second pipe to open/close the second flow path, and having a second through-hole;
and
an opening/closing unit configured to control and arrange the first and second balls to communicate the first flow path, the first through-hole, the second through-hole and the second flow path,
wherein the opening/closing unit includes a gear train configured to sequentially control the opening/closing of the first and second balls through one control operation thereof.
