Description

Technical Field

[0001] The utility model specifically relates to an integrated heat metering box for heat metering and status monitoring, belonging to the technical field of heat metering boxes. Background Technique

[0002] During the installation of the heat energy meter, a box body is usually arranged outside the heat energy meter, and the heat energy meter and other instruments are placed in the box body. At the same time, both the water inlet pipe and the return water pipe pass through the box body. However, the assembly process and technology of the common box bodies on the market are complex. Especially when the heat energy meter or other instruments malfunction, the heat energy meter and other instruments need to be disassembled together with the water inlet pipe and the return water pipe, and the disassembly and assembly work is rather cumbersome. For this reason, the Chinese patent authorization publication number: CN218994535U discloses a household heating metering box, which forms a clamping connection for the water inlet pipe by using the water inlet pipe receiving groove on the fixing plate and the water inlet pipe placement groove on the box body, and forms a clamping connection for the return water pipe by using the return water pipe receiving groove on the fixing plate and the return water pipe placement groove on the box body. Another example is the Chinese patent authorization publication number: CN219178775U, which discloses an integrated heat metering box for heat metering and status monitoring, aiming at abnormal opening of the box door alarm and remotely adjusting the opening of the electric regulating valve by the remote control center. However, the above heat metering boxes only have the heat metering function and cannot monitor the status of the household heating pipe network and perform balance adjustment.
