Title:
NOZZLE-TYPE STEAM TRAP
Document Type and Number:
WIPO Patent Application WO/2018/100753
Kind Code:
A1
Abstract:
[Problem] To increase cooling capability for a fluid discharged by a nozzle-type steam trap. [Solution] A high-pressure chamber is communicated with a steam introduction port. A discharge chamber is communicated with a drain discharge port. A low-pressure chamber is provided to the downstream side of the high-pressure chamber and the upstream side of the discharge chamber. A nozzle 7 sprays a fluid inside the high-pressure chamber into the low-pressure chamber on the basis of a pressure difference between the high-pressure chamber and the low-pressure chamber. Of a wall part sectioning off the high-pressure chamber, the periphery of a suction port of the nozzle is gently recessed into a circular shape concentric with the suction port. The turbulent flow of the fluid inside the high-pressure chamber is rectified by the ejector phenomenon and the Coandă phenomenon, and the width and speed of the fluid sucked into the nozzle are increased. The cooling capability for the fluid is thereby increased, and the fluid is therefore reliably converted to a liquid phase and can be effectively discharged as drainage.
