Pipeline pigging receiving and dispatching ball wound packages is put with acousto -optic warning

The utility model relates to a pipeline pigging receiving and dispatching ball wound packages is put with acousto -optic warning, including the base support with install the receiving and dispatching ball barrel on the base support, be equipped with logical ball indicator, on -the -spot manometer, emergent blowdown piping, relief valve and torch blowdown piping on receiving and dispatching ball barrel upper portion, be connected with the drain in receiving and dispatching ball barrel bottom, receiving and dispatching ball barrel one end is equipped with service mouthful, another tip is equipped with fast open -blind board, characterized in that: still install on receiving and dispatching ball barrel upper portion can accurate monitoring receiving and dispatching ball section of thick bamboo internal pressure, improve operation personnel alertness, effectively reduce the acousto -optic warning system of maloperation. The advantage is: single on -the -spot manometer unsafe drawback of pressure monitoring possibility when receiving and dispatching ball operation later stage low pressure can be effectively avoided, the interior pressure monitoring's of a receiving and dispatching ball section of thick bamboo reliability has been increased substantially, still accessible acousto -optic warning system warns dangerous existence in real time, improves operation personnel's awareness of safety and alertness to reduce the maloperation, reduce receiving and dispatching ball operation accident.
