Title:
ANTIFREEZE LIQUID CHANGEOVER VALVE
Document Type and Number:
Japanese Patent JP2022172712
Kind Code:
A
Abstract:
To provide an antifreeze liquid changeover valve which can automatically switch flow of an antifreeze liquid to be supplied to a snow melting roof panel assembly by sensing heat and achieves excellent maintainability.SOLUTION: An antifreeze liquid changeover valve 10 is installed at an antifreeze liquid outlet side of a snow melting roof panel while connecting a panel body of the snow melting roof panel with a bypass and includes a function for automatically switching flow of the antifreeze liquid. The antifreeze liquid changeover valve 10 is a roof panel fixture with a steam switching function including: a shielding open member 20 which repeats expansion and contraction according to a sensed temperature; a panel body side steam passing port; a bypass side steam inlet 50 including a bypass side steam introduction member 40; and a steam discharge port 70 including steam discharge members 60 for discharging steam entering from the panel body side and steam entering from the bypass side.SELECTED DRAWING: Figure 2
