定风量阀
定风量阀：在空调系统中，某此场合要求风量恒定不变，我司根据市场需要开发了机械式及电动式两大系列的定风量阀，满足工程中风量精确控制的要求。它由叶片、气囊和弹簧片相连的凸轮等组成，气囊有小孔与阀门的叶片相通，可根据管道内压力的变化而变化，使两者达到动态平衡，从而保持风量恒定不变。材质：镀锌板/镀镁铝锌板
控制方式：分机械式与电动式两种
结构：矩形与圆形
Fixed valve. It is used to fix the blowing rate. Some places require the stable blowing rate in air condition system. We develop fixed valve in two types, mechanical and electrodynamics, which can meet the accuracy control requirement. It is combined by blades, air bag and cam linked by leaf spring. There are holes link the air bag and valve, which can control the blowing rate according to the pressure.
Material: galvanized plate, magnesium aluminum zinc plate.
Control mode: mechanical operation, electrodynamic operation
Construction: rectangle, round
