产品介绍
一、进口电动套筒调节阀概述
进口电动套筒调节阀(美国威盾VTON,Electric sleeve control valve)由VTRD型系列直行程电动执行机构和套筒阀两部分组成。以单相交流220V电源为动力,接受0~10mA或4~20mA直流信号,自动地控制调节阀开度,从而达到对管道流体介质的压力、温度、流量、液位等工艺参数的连续调节。进口电动套筒调节阀具有比双座阀大的流量系数,且允许压差大,稳定性好,工作时不易产生振动,适用性强等优点,广泛地应用于电力、冶金、石油、化工、轻工等工业部门的自动控制系统。
The imported electric sleeve control valve (VTON, Electric sleeve control valve) is composed of two parts: a VTRD series linear electric actuator and a sleeve valve. Powered by a single-phase AC 220V power supply, it receives 0-10mA or 4-20mA DC signals and automatically controls the opening of the regulating valve, thereby achieving continuous adjustment of process parameters such as pressure, temperature, flow rate, and liquid level of the pipeline fluid medium. The imported electric sleeve regulating valve has the advantages of a larger flow coefficient than the double seat valve, a larger allowable pressure difference, good stability, less vibration during operation, and strong applicability. It is widely used in automatic control systems in industrial sectors such as power, metallurgy, petroleum, chemical, and light industry.
二、进口电动套筒调节阀产品特点
阀体按流体力学原理设计的等截面低流阻流道,额定流量系数增大30%。
可调节范围大,固有可调比为50,流量特性有直线和等百分比。
电动套筒调节阀阀塞设有上、下方的均压孔,不平衡力小,阀稳定性好,套筒互换性强,使用压差大。
调节切断型采用软密封结构阀芯,达VI级泄漏标准(零泄漏)。
伺服放大器采用深度动态负反馈,可提高自动调节精度。
电动操作器有多种形式,可适用于4~20mA.DC或0~10mA.DC。
电子型电动调节阀可直接由电流信号控制阀门开度,无需伺服放大器。
波纹管密封型调节阀对移动的阀杆形成完全的密封,堵绝流体外漏。
