描述--
气动蝶阀由气动活塞式执行机构和O型蝶阀组成,以压缩空气为动力源,通过电磁阀可实现对阀门开关控制,它可以准确地按指令动作,是对阀门实现远控、集控和自控必不可少的驱动装置。
Pneumatic butterfly valve consists of pneumatic piston actuator and O butterfly valve, with compressed air as a power source, through the electromagnetic valve to realize the valve switch control, it can accurately press the instruction action, is the valve to achieve remote control, centralized control and automatic control of the driving device.
控制原理--
双作用气缸--在失电或失气时,阀门处于失电或失气时的位置,以确保继续生产;
单作用气缸--在失电或失气时,阀门处于 原始极限位置(全开或全闭)。
Double acting cylinder - when the power is lost or the gas is lost, the valve is in the position of power failure or loss of gas to ensure continuous production.
Single acting cylinder - the valve is in the original limit position (full or full closed) when the power is lost or the gas is lost.
带配附件--
回讯器:也叫限位开关,远程反馈开关信号 (普通型、防爆型可选);
电磁阀:双作用选二位五通、单作用选二位三通(普通、防爆;多种电压可选);
三联件:可对气源起稳压、过滤作用;
手轮机构:在气源故障情况下,转动手轮机构,可实现手动开、关阀;
电-气定位器:输入4~20mA信号,实现阀门调节功能(普通、防爆可选);
