进口电动高温套筒调节阀
进口电动高温套筒调节阀产品叙述:
美国《LAINE》莱恩-进口电动高温套筒调节阀采用顶部导向结构,由电动执行器和精小型调节阀体组成,内含饲服功能,接受统一的4-20mA或1-5V·DC的标准信号,将电流信号转变成相对应的直线位移,自动地控制调节阀开度,达到对管道内流体的压力、流量、温度、液位等工艺参数的连续调节。广范应用于静确控制气体、液体、蒸汽等介质,工艺参数加如压力、流量、温度、液位保持在给定值。 电动单座调节阀特别适用于允许压差小,而允许泄漏量也较小压差不大的工作场合。
Laine imported electric high temperature sleeve control valve adopts top guide structure, which is composed of electric actuator and fine small control valve body. It has feeding function, receives unified standard signal of 4-20mA or 1-5V · DC, converts current signal into corresponding linear displacement, and automatically controls the opening of control valve, so as to achieve the control of fluid pressure, flow, temperature and pressure in pipeline Continuous adjustment of process parameters such as liquid level. Widely used in accurate control of gas, liquid, steam and other media, process parameters such as pressure, flow, temperature, liquid level to maintain a given value. The electric single seat control valve is especially suitable for working occasions with small allowable pressure difference and small allowable leakage.

进口电动高温套筒调节阀产品优点:
1)流体对阀芯作用方向都处于流开状态,故工作稳定性好。
2)除了阀盖处衬套导向外,阀芯侧面与阀座内表面也有导向作用,导向面积大,工作可靠。
3)伺服放大器采用深度动态负反馈,可提高调节精度。
4)电动操作器有多种形式,可适用于4~20mA.DC或0~10mA.DC。
5)电动高温套筒调节阀可直接由电流信号控制阀门开度,无需伺服放大器。
6)节省自动化投资,与单座、双座或套筒调节阀相比,组成同样的系统可省掉一个阀,简化系统。
7)波纹管密封型对移动的阀杆形成完全的密封,堵绝流体外漏。
