环保蝶阀 Green Butterfly Valve

蝶阀体积小、重量轻、口径越大相对其他阀更经济实惠。蝶阀处于完全开启位置时，蝶板厚度是介质流经阀体的唯一的阻力，因此通过该阀门所产生的压力降很小，当开启度在大约15度至70度之间时，又能进行灵敏的流量控制，因此大口径的流量调节，阀具有较大的优势。Butterfly valve is small in size, liaht in weight, and has biager diameter, and is more economicaland practical than other valves. When butterfly valve is in the fuly open position, the thicknessof butterfly plate is the only resistance of the medium flowing through the body. So the pressuredropped by the valve is small. When it is open in about 15 degrees to 70 degrees, it c
