A pipe member is installed between the reservoir 20 and the pump member 34 and between the pump member 34 and the boiler member 36 to transfer water as a fluid.

The reservoir 20 is connected to the conduit member by the connecting portion 14, the conduit member is divided into the first conduit member 30 and the second conduit member (32).

The first conduit member 30 connects the connecting portion 14 and the pump member 34, and the second conduit member 32 connects the pump member 34 and the boiler member 36. do.

Pressurization portion 50 is connected to the conduit member to increase the pressure of the fluid flowing inside the conduit member.

The fluid may be composed only of water, which is a liquid, and steam including water may also constitute a fluid according to an embodiment of the present invention.

The pressing unit 50 may be used in the technical idea of applying a constant pressure to the water flowing inside the pipe member, in the present invention, in one embodiment of the present invention, the pressing unit 50 provided with an orifice using Bernoulli's theorem. Will be used.

The orifice is used for adjusting and measuring the flow rate and is produced in a circular shape that is easy to process. If an orifice with a diameter d (D> d) is inserted in the middle of a flow pipe having a diameter D, immediately after that, the flow velocity changes and the pressure of the fluid is measured using Bernoulli's theorem in which the pressure drops.

The pressing unit 50 is provided with an inner passage 55 narrower than the inner diameter of the conduit member. In detail, the inner passage 55 of the pressing portion 50 has a shape that gradually narrows the hole toward the central portion 54 from the inlet portion 52 and then widens again through the central portion 54. .

On the other hand, both sides of the pressing portion 50 is provided with a coupling groove 59 for inserting the conduit member, the side surface of the coupling groove 59 is sawtooth-shaped fixing projection 60 is formed protruding.
