一、概述Outline
QJ(D/S)V、QJ(D/S)VY型精小型气动V型调节球阀由气动活塞式执行机构和带V型切口的部分球面形的整体式球阀组成。属旋转类调节球阀。
气动V型调节球阀以压缩空气为动力源。接受控制系统来的4—20mA DC(0—10mA DC)讯号,通过电气转换或电—气阀门定位器将电信号转化成阀门动作所需要的气信号,对调节球阀进行调节。
气动V型调节球阀,其流道通畅,流量系数大,可调范围大,密封性能好。其带V型切口的阀芯,对阀座具有良好的剪切作用,使该产品适用于石油化工、造纸、污水处理及冶金等行业,对含有纤维和颗粒的悬浊液介质进行流量控制,特别适用于制浆、造纸生产过程中的纸浆、白水、黑液、白液等悬浮颗粒流体及浓浊状流体介质的自动调节。
气动活塞式执行结构可分为单作用和双作用两种。双作用使用在失电或失气时,阀门处于失电或失气时,阀门处于原始极限位置(全开或全闭),以确保生产过程处于**位置。
