Abstract

A sensor connection structure is disposed in a manifold including a main pipe, a plurality of branch pipes connected to each of left and right of the main pipe, and a plurality of steam traps (valves) disposed in the branch pipes. The sensor connection structure includes: a plurality of sensors respectively disposed on the steam traps; a plurality of connection boxes arranged along an axis of the main pipe, connected to each other in series through electric wire pipes, and connected to the plurality of sensors through electric wire pipes; and a terminal unit connected to one of the plurality of connection boxes through an electric wire pipe.

First claim

What is claimed is:

1. A sensor connection structure configured to be disposed in a pipe unit, the pipe unit including a main pipe, a plurality of branch pipes connected to each of left and right of the main pipe, and a plurality of valves disposed in the branch pipes, the pipe unit being configured to allow fluid to flow in the pipe unit, the main pipe extending vertically being attached to, and supported by, a strut extending vertically, the sensor connection structure comprising:
a plurality of sensors that are respectively disposed on the plurality of valves and detect operating states of the valves;
a plurality of connection boxes arranged along an axis of the main pipe, directly connected to each other in series through electric wire pipes, directly attached to the main pipe through a plate-shaped attachment base, and directly connected to the plurality of sensors through electric wire pipes; and
a terminal unit connected to one of the plurality of connection boxes through an electric wire pipe.

2. The sensor connection structure of claim 1 , wherein the main pipe is attached to, and supported by, a front side of the strut.

3. The sensor connection structure of claim 1 , wherein each of the plurality of connection boxes is connected to one of the sensors located at the left of the main pipe and one of the sensors located at the right of the main pipe.

4. The sensor connection structure of claim 1 , wherein the terminal unit is disposed on the main pipe.
