我厂锻造加热炉的余热利用系统中,供洗澡、生活用水的循环水箱,以前是靠人工操作闸阀控制进水,这样常因看不见水位或突然停水、停电而时水溢出水箱,既浪费了水,又影响了加热炉的寿命。为此,我们在水箱的进水口安装了一个公称通径为D_g40mm的浮球阀(与之相适用的浮球规格为250mm)。当水箱中水位低于规定位置时,浮球阀即自动打开,让水进入水
I plant forging furnace waste heat utilization system for bathing, domestic water circulation tank, the previous is by manually operated gate valve control of water, so often can not see the water level or a sudden stop water, power outages and sometimes water overflow tank, both waste The water, but also affect the life of the furnace. For this purpose, we installed a float valve (nominal float diameter of 250 mm) with a nominal diameter of D_g40mm at the water inlet of the tank. When the water level in the tank is lower than the specified position, the float valve automatically opens and allows water to enter the water
