Claims

[Scope of utility model registration request]

The main valve body is placed between the primary and secondary chambers of the flash valve body, and the pressure is located behind the main valve body and communicates with the primary chamber through a small hole and the secondary chamber through a relief valve. an antifreeze valve chamber provided outside the main body and communicated with the primary side chamber and the secondary side chamber through first and second communication holes, respectively, and an antifreeze valve disposed within the valve chamber, and In the antifreeze flush valve, the antifreeze valve is configured to open or close either the first or second communication hole in response to the temperature of the water supply, wherein the water supply between the primary side chamber and the inlet of the first communication hole is provided. An antifreeze flush valve characterized by a strainer placed in the flow path.
