Which brand of imported pressure reducing valve is better?
Whether the imported pressure reducing valve is good or not mainly depends on the accuracy of the pressure reduction balance and the performance of the voltage stabilization.; Pressure reducing valve is a type of valve product with relatively high requirements; If it is a domestically produced pressure reducing valve for water use, it can also be used, such as the DeTaiKe brand in Beijing; If it is a steam pressure reducing valve and a gas pressure reducing valve, they are generally imported; For example, which brand of imported pressure reducing valve is better between the UKs Speisak and the USs Weidun VTON depends mainly on the product type. For example, for water pressure reducing valves, the better brands include the USs Tyco, the USs Yuanlan Weidun VTON, and the German Lite; If it is a steam pressure reducing valve, the main ones are Speisak from the UK, VTON from the US, and Armstrong from the US; If it is a gas pressure reducing valve, there are mainly American Weidun VTON, American Jierui, and Japanese Yaoxi Dakai;
2. Working principle of heat meter
The heat meter calculates the actual heat consumption value by measuring the flow rate of the heating pipeline and the temperature difference between the inlet and outlet water.
1. Core working principle: The heat meter uses the heat calculation formula Q=∫ c × ρ × Δ T × qv × dt, where - Q is the cumulative heat value (unit: kWh or MJ) - c is the specific heat capacity of water (4.1868 kJ/kg ·℃) - ρ is the density of water (changes with temperature) - Δ T is the temperature difference between the inlet and outlet water (℃) - qv is the instantaneous flow rate (m ³/h) - dt
III. Installation and use specifications for missing pants and hands 1 Requirements for front and rear straight pipe sections: flow meter front 10DN and rear 5DN. 2. Installation position of temperature sensor: symmetrically arranged supply and return pipes. 3 Regular calibration cycle: 2 years/time (according to JJG 225-2001 standard) 4 Working pressure range: ≤ 1.6MPa (common specifications for civil buildings)
IV. Technical standard requirements comply with EN 1434-2015 standard requirements: - Overall accuracy level: 2-4 levels - Maximum allowable error: ± (2+4 Δ Tmin/Δ T) - Pressure loss:<25kPa (at rated flow) Note: The current data is based on the "Technical Regulations for Heating Metering" (T/CECS 1367-2023) released in 2023 and the latest technical manuals of mainstream manufacturers such as Kamstrup and Itron. The actual selection of Hu Bian needs to be calculated based on parameters such as pipeline diameter and medium temperature.
