特徴とする自動ドレン弁。 A float that is stored inside a valve box and floats when room-temperature liquid is stored; and a main valve body that is connected to the float and opens a main valve seat when the float floats to connect an upper flow path and a drain discharge channel. , has a low-temperature thermal actuation part that is installed near the main valve body and undergoes thermal displacement when low-temperature liquid flows into the valve body, and when the low-temperature liquid is thermally displaced, the lower valve seat is opened and the inflowing room-temperature liquid is directed to the drain discharge path. It has a lower valve body that is caused to flow down, and a low-temperature thermal actuation part that is attached near the top of the float and undergoes thermal displacement when the low-temperature liquid flows into the valve box, and when the low-temperature liquid is thermally displaced, the upper valve seat is opened and the low-temperature liquid flows in. An automatic drain valve characterized by comprising: an upper valve body for causing water to flow down into a drain discharge path.
