IMPROVEMENT TO DOUBLE-WALLED VALVE BODIES

摘要

The invention relates to a valve (19) comprising a body and a shutter (18) mounted such that it can move inside the body, the body comprising a first shell (20) and a first liner (21) made of plastic covering the internal face of the first shell and delimiting a first cavity (38). The body further comprises a second shell (64) and a second liner (51) made of plastic covering the internal face of the second shell and delimiting a second cavity (66) which communicates with the first cavity via an opening (56). The cavities extend along two respective oblique longitudinal axes (26, 39), the liners are connected by a sealed connection, and the shutter is mounted such that it is translationally mobile in the first cavity between a position in which the valve is closed and a position in which the valve is open.
