Pipe Assembly Unit With Built-In Flow Sensors
First Claim
1. A pipe assembly unit with built-in flow sensors in which a pipe assembly of manifold construction is integrally formed with a main pipe and multiple branch pipes, the main pipe having an opening with a square flange at each end thereof and the multiple branch pipes branching from the periphery of the main pipe, the square flange having a bolt-joint hole at each square corner thereof, and each of the multiple branch pipes being provided with a flow sensor which detects the flow rate of a fluid flowing therethrough, the pipe assembly unit further provides with a pipe adapter which is detachably attached face to face to the square flange of the main pipe, the pipe adapter comprising a female threaded portion to communicate with the main pipe, an adapter square flange around the female threaded portion, the adapter square flange having an adapter bolt-joint hole at each square corner thereof, the adapter bolt-joint holes respectively confront the bolt-joint holes of the square flange of the main pipe, and a pair of legs protruding horizontal from a pair of the square corners of the adapter square flange, wherein the adapter square flange is selectively turnable by a 90-degree around an axis of the main pipe so as to connect the pipe adapter to the manifold with four bolts respectively inserting through the adapter bolt-joint holes and the selected corresponding bolt-joint holes to fasten the pipe adapter to the manifold.

Abstract
Cost is reduced by simplifying piping work and reducing the number of parts. At the same time, the degree of freedom in the arrangement of piping is raised by making the mounting posture of the piping variable. A pipe assembly unit with built-in sensors 1 is fabricated by integrating a main pipe 2 and multiple branch pipes 3, 3, . . . which branch from the main pipe 2 and by building, in the multiple branch pipes 3, 3, . . . , a flow sensor 4 which detects the flow rate of a fluid flowing through a conduit 31 of each of the branch pipes 3, and the use of a conventional seal construction using a nipple in connections between the main pipe 2 and the branch pipes 3 is abolished. A pipe adapter 73 having legs 734 is detachably attached to opening ends of the main pipe 2 and the legs 734 are fixed to an installation surface A by changing the orientation of the pipe adapter 73, whereby the mounting posture of the pipe assembly unit 1 is made variable.

2. A pipe assembly unit with built-in flow sensors having a plurality of pipe assembly manifolds, in which each pipe assembly of manifold construction is integrally formed with a main pipe and multiple branch pipes, the main pipe having an opening with a square flange at each end thereof and the multiple branch pipes branching from the periphery of the main pipe, the square flange having a bolt-joint hole at each square corner thereof, and each of the multiple branch pipes being provided with a flow sensor which detects the flow rate of a fluid flowing therethrough,
wherein the square flange of one manifold is selectively turnable by a 90-degree around an axis of the main pipe so as to connect the manifold to another manifold with four bolts respectively inserting through the bolt-joint holes of the former manifold and the selected corresponding bolt-joint holes of the latter to fasten both the manifolds.
