Title:
PIPING AUTOMATIC CONNECTION CHANGE-OVER DEVICE
Document Type and Number:
Japanese Patent JP3429916
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a piping automatic connection change-over device which does not furnish numerous expensive flow meters, does not have an excessive redundancy as the machine, and of a low cost as a whole.
SOLUTION: To a unit A1, connecting couplings a1 to a5 are arranged on a straight line, and the connecting couplings a1 to a5 are connected to raw material lines or the like. To a unit B2, connecting couplings b1 to b3 are arranged on a straight line same as the connecting couplings of the unit A1, and the connecting couplings b1 to b3 are connected to tank lines or the like. Between the unit A1 and unit B2, a unit C3 is positioned, and the unit C3 has a connecting coupling c1 connected to the connecting couplings of the unit A1, and a connecting coupling c2 connected to the connecting couplings of the unit B2. And the connecting couplings c1 and c2 connected by a single flexible hose 10 furnishing a mass flow meter 9 are assembled to moving bodies respectively, and they move only in the lateral direction.
