谈《压差积分式微流计量补偿表前阀》检测方法的应用

Application of “Pressure Differential Integral Micro Flow Metering Compensation Meter Front Valve” Detection Method

压差积分式微流计量补偿表前阀与冷水水表(简称水表)配合使用,并安装在水表前端(即上游端)。在不影响水表正常计量的情况下,能够保证水表进行滴水计量。其原理是利用压差积分技术对水表进行脉冲式供水使其产生转动,解决了水表在微小流量下不能计量或计量不准确的难题,并具有防【水表】潜动功能。

The pressure differential integral micro flow metering compensation table front valve is used in conjunc- tion with the eold water meter （ short water meter）, and is installed at the front end of the water meter （ that is the upper reaehes）. In the case of not affecting the normal measurement of the water meter, the meter can be ensured to measure the drip water. The principle is the use of differential pressure integral technique of water meters pulse wa- ter to produce rotation, solve the problem of the water meter can not measure or inaccurate measurement in micro flow, and can prevent the [ meter] creep function.
