Ball valve |
摘要 |
<p>Shut-off member in the form of a ball valve for a liquid or gaseous fluid, particularly for those which contain fine solids - having a housing, a housing flow passage with an inflow section and an outflow section, a shut-off ball, a shut-off ball flow passage and an actuator for the shut-off ball. The inlet of the inflow section (3) of the housing flow passage into the shut-off ball flow passage has a smaller cross-section than the beginning of the shut-off ball flow passage (6). The outlet of the shut-off ball passage into the outflow section (4) of the housing flow passage has a smaller cross-section than the beginning of the outflow section of the housing flow passage. The shut-off ball is pressed against the seat rings by the action of a spring force (10). The differences in cross-section between the inflow section and the shut-off ball flow passage and between the shut-off ball flow passage and the outflow section are greater than the offset between the said components caused by manufacturing tolerances and assembly tolerances. <IMAGE></p> |
