进口电动调节阀详细描述,用途/原理,报价
【进口电动调节阀】详细说明：
直行程电动执行机构和双座 阀两部分组成，座阀有上、下两个阀芯球，流体作用在上、下阀芯上的推力，其方向相反而大小接近，不平衡力很小，允许压差大，额定流量系数比同口径的单座阀大，但该阀的泄漏较单座阀大。 适用于对***量要求不严格，阀前后压差较大的干净介质场合。电动双座调节阀以单相交流220V电源为动力， 接受4~20mA直流信号，自动地控制阀门的开度，从而达到对 压力、温度、流量、液位等工艺参数的连续调节。是生产过 程自动调节系统中的一个重要环节，广泛应用于电力、冶金 、石油、化工、轻工、食品等工业部门的自动控制系统中。
Direct-stroke electric actuator and double-seat valve are composed of two parts. Seat valve has two spool balls, upper and lower. The thrust of fluid acting on upper and lower spools is opposite in direction and close to each other. The unbalanced force is ***all, the allowable pressure difference is large, the rated flow coefficient is larger than that of single-seat valve with the same caliber, but the leakage of the valve is larger than that of single-seat valve. It is suitable for clean media occasi*** where the leakage requirement is not strict and the pressure difference between front and back of the valve is large. Electric two-seat regulating valve is powered by single-phase AC 220V power supply, receives 4-20mA DC signal, and automatically controls the opening of the valve, so as to achieve continuous adjustment of pressure, temperature, flow rate, liquid level and other process parameters. It is an important link in automatic regulation system of production process, and is widely used in automatic control system of electric power, metallurgy, petroleum, chemical industry, light industry, food and other industrial departments.

【进口电动调节阀】特性：
电动双座调节阀由电动执行机构和双座调节阀体组成，电动双座调节阀适用于压差较大场合。按阀内件密封部分材质分又有金属-金属和非金属-金属密封两种，后者阀关闭时泄漏量可达到Ⅵ级(零泄漏)标准。按填料不同可分为一般填料密封和波纹管密封两种，前者用于一般场合，而后者用于不允许外漏的特殊场合，流量特性为线性或等百分比。
