进口电动隔膜调节阀,详细说明,特点/用途,报价
【进口电动隔膜调节阀】详细说明：
电动隔膜调节阀由直行程电动执行机构和隔膜阀组成。电动执行机构为电子式一体化结构，内有伺服放大器,输入控制信号（4-20mADC或1-5VDC）及电源即可控制阀门开度,达到对压力、流量、液位、温度等工参数的调节。具有动作灵敏、连线简单、流量大、体积小、调节精度高等特点。控制精度和性能比有明显提高。隔膜阀体流通平滑、节流元件为弹性隔膜阀，阀盖上无填料函。因而阀流通能力比一般调节阀大且无泄漏，在许用压差范围内可作切断阀用。该阀适用于高粘性流体、悬浮状颗粒、纤维介质和***介质、腐蚀性介质的调节场合。
The electric diaphragm regulating valve is composed of a direct stroke electric actuator and a diaphragm valve. The electric actuator is an electronic integrated structure with servo amplifier. The valve opening can be controlled by input of control signal (4-20mADC or 1-5VDC) and power supply, so as to adjust the working parameters such as pressure, flow, liquid level and temperature. It has the characteristics of sensitive action, simple connection, large flow, ***all volume and high adjustment precision. The control accuracy and performance are ***iously improved. The flow of diaphragm valve body is ***ooth, the throttling element is elastic diaphragm valve, and there is no filling box on the valve cover. Therefore, the flow capacity of the valve is larger than that of the general control valve and there is no leakage. It can be used as a shutoff valve in the allowable pressure difference range. The valve is suitable for regulating high viscous fluids, suspended particles, fiber media, toxic media and corrosive media.
【进口电动隔膜调节阀】特点：
采用轻型执行机构，高度及重量均可减小30%。阀体内表面有多种材料涂复层，避免介质直接接触，承受强阀腐蚀性介质的腐蚀。阀门关闭时，内、外泄漏量为零，特别适合于***介质或不允许污染介质的阀节。流路简单，阻力小，额定流量系数比同口径单座，套筒调节阀大。零配件材料：阀体：HT200、ZG230～450或下述材质衬里隔膜：丁荃胶、天然胶、聚四氟乙烯波纹。薄膜：***橡胶夹增强涤纶织物
