Title: Method of draining a number of steam equipment whose load varies frequently
Inventor: HONDA NORIYUKI
IPC: F16T1/00
Filed: 1992-04-13
Abstract: PURPOSE:To reduce the total cost for draining a number of steam equipment whose load varies frequently. CONSTITUTION:Each drain pipe 4 of a number of steam equipment 1 whose load varies frequently is connected in lump to a drain collecting pipe 6, allowing each orifice 5 to be interposed. Further, a flow rate adjusting valve 7 is installed on the discharge port side of the drain collecting pipe 6, and the flow rate of the discharged fluid is adjusted, and balanced with the drain discharge quantity supplied from each steam equipment 1. The orifice can be obtained with the considerably less initial cost and renewal cost in comparison with the conventional valve opening/closing type drain trap. Further, even if steam leaks from the steam equipment in the light loaded state, a back pressure acts on the orifice outlet side, accompanied with the adjustment of the flow rate adjusting valve, and the leak quantity is regulated to the less value, and the supplement cost for steam is hardly varied in the case of the variation through the lapse of time of the conventional valve opening/closing type drain trap.
