Sampler valve for use with gases

摘要

The valve has a tubular housing (1) with sample extraction socket (2), gas intake (3) with valve (4) and gas discharge (5) with valve (6). It has a central bore with piston (7), which has a head (10) facing container or tube (14). When the sampler valve is closed, a conical sealing face presses against an edge (11) of the housing bore to form a line seal.The piston has a transverse bore (9) which is in contact with its longitudinal bore (8), and permits medium flow to the socket on the other side of the seal (28). The longitudinal bore is connected to the gas intake, so that this is constantly in connection with the gas discharge and the socket on the other side of the seal.
