Pipe valve for distributing fluids in e.g. submarine, has spherical casing with pair of flat sections and junction parts to define successive distinct zones that permit assembling and disassembling of casing in body of valve

摘要

The valve has a spherical casing (2) comprising a pair of parallel flat sections (2a, 2b) and junction parts (2c, 2d) for defining four successive distinct zones (Z1-Z4) that permit assembling and disassembling of the casing in a body of the valve for ensuring successive functions. The junction parts have a same curvilinear profile and have different in size by forming a truncation (2e) established between the flat section (2a) and the junction part (2c).
