DIRECT ACTING HYDRAULIC TRIP BLOCK WITH MAJORITY VOTING |
摘要 |
<p>A direct acting hydraulic voting trip block defines three separate paths between an inlet and an outlet port. Each path is intersected by a valve cylinder. Valve pistons in each valve cylinder are configured, in the activated position, to block two of thee different paths. As long as at least two of the pistons are in the activated position, communication between the inlet and outlet ports is prevented, thus providing a hydraulic majority voting logic valve system.</p> |
