LX-4 large-caliber intelligent wireless heating valve adopts NB-IOT Internet of Things technology. It is a high-tech toll management product independently developed by our company for the heating charge of domestic heating majors. It is suitable for large-diameter plumbing of independent heating pipes. Heating system. The working principle is to install intelligent heating valve in the heating inlet or the return water pipe. After the user pays the fee, the user can remotely open the valve for heating through the “heating information service platform” software, without paying the fee and heating, and realize the intelligent management of prepaid heating. This smart wireless heating valve adopts NB-IOT narrow-band Internet of Things, and the remote transmission network is stable and reliable. The built-in temperature sensor in the watch body can automatically upload the heating temperature of the pipe, which is convenient for the administrator to adjust the built-in valve switch angle of the intelligent wireless heating valve according to actual needs, and achieve the energy saving and emission reduction target by adjusting the heating temperature. It is an ideal scientific management heating valve tool for heating and charging departments, intelligent wireless heating valve tool, NB Internet of Things heating valve management tool。
