| 摘要 |
The invention relates to a two-directional or one-directional valve with a spherical cock more particularly intended for large cross- section pipes transporting fluids at high pressure and characterised in that it comprises a spherical cock 3 traversed by a passage 38 elbowed at a right angle and interacting in the closed position on either side of its opposing walls linked via a channel 43 contiguous with the passage elbowed at a right angle 38 with sealing rings 4, 11 and/or 5, 10 in such a way that the loads directly exerted by the fluid on the spherical cock 3 cancel each other out. <IMAGE>
