QJ(D/S)V、QJ(D/S)VY型精小型气动V型调节球阀
【简单介绍】
【详细说明】
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安全位置。
QJ (D / S) V, QJ (D / S) VY fine small pneumatic V-type ball valve by the pneumatic piston actuator and with a V-notch portion of the overall spherical shape of ball valve components. Is a rotating type ball valve.
V-ball valve pneumatic compressed air as power source. Accept the control system to the 4-20mA DC (0-10mA DC) signal through the electrical conversion or electric - gas valve positioner to the valve movement into electrical signals needed gas signal, the ball valve to adjust.
Pneumatic V-ball valve, the flow smooth, flow coefficient, adjustable range, good sealing performance. The V-shaped incision with the spool of the valve seat has a good shearing, so that the product is suitable for petrochemical, paper, sewage treatment and metallurgical industries, containing fibers and particles in suspension media flow control , especially for pulp and paper production process of paper pulp, white water, black liquor, white liquor and other suspended particles in the fluid and the fluid medium Nongzhuo like the automatic adjustment.
Pneumatic piston implementation structure can be divided into single and double acting two. Dual role in the loss of power or loss of use of gas when the valve is out of power or loss of gas when the valve is in the original extreme position (open or closed) to ensure that the production process in a secure location.
