Claims

[Scope of utility model registration request]

(1) A drain pot that opens into a steam pipe and temporarily stores drain generated in this steam pipe, a drain pipe that connects this drain pot and a condenser, and a water level in the drain pot that is provided in this drain pipe. In a steam pipe drain discharge device comprising a drain discharge regulating valve that is opened when the drain discharge regulating valve is opened when the drain discharge regulating valve of the drain pipe is branched from the upstream side of the drain discharge regulating valve of the drain pipe, a bypass pipe connected downstream of the regulating valve; a gate valve provided in the bypass pipe and opened when the water level in the drain pot exceeds the predetermined value and further rises above this value; and the bypass pipe. A drain discharge device for a steam pipe, comprising: a throttle mechanism provided upstream or downstream of the gate valve in the pipe.

(2) The steam pipe drain discharge device according to claim 1, wherein the steam pipe is a main steam pipe.

(3) The steam pipe drain discharge device according to claim 1, wherein the steam pipe is a bleed pipe.

(4) The steam pipe according to any one of claims 1 to 3 of the utility model registration claim, wherein an on-off valve is provided between the drain discharge regulating valve upstream of the drain pipe and the bypass pipe branch part. Drain discharge device.

(5) The utility model according to any one of claims 1 to 4, wherein an on-off valve is provided between the drain discharge regulating valve downstream of the drain pipe and the bypass pipe connection part. Steam pipe drain discharge device.

(6) A drain discharge device for a steam pipe according to any one of claims 1 to 5, wherein the throttle mechanism is an orifice.
