QJ(D/S)DX型气动橡胶调节蝶阀  的详细介绍

一、概述Outline

QJ(D/S)DX型精小型气动橡胶蝶阀是由气动活塞式执行机构和衬里蝶阀组成,属旋转类控制阀。
该产品以压缩空气为动力源,接受控制仪表的4-20mA信号(或开关信号),通过电-气阀门定位器(或电磁阀)实现对阀门的连续调节(或位式控制)。
橡胶衬里蝶阀是一种阀体内腔衬有橡胶的防腐蚀蝶阀。控制腐蚀性流体不与阀体接触,阀体可用普通铸铁或碳钢,由此降低蝶阀的成本。衬里材料有各种橡胶可供选择,还可更换。
该产品结构简单,输出力矩大,性能优越。蝶阀通常适用于控制密封要求比较高的腐蚀性流体。

QJ (D / S) DX-type fine small pneumatic rubber valve is pneumatic piston actuator and lining butterfly valve, is a rotary type control valve.
The product is compressed air as power source, to accept 4-20mA control signal meter (or switch signals), through the electric - gas valve locator (or solenoid valve) to achieve the continuous adjustment of the valve (or bit control).
Rubber lined butterfly valve is a body cavity lined with rubber anti-corrosion butterfly. Corrosion control and body fluid does not contact the valve body can be an ordinary cast iron or steel, thus reducing the cost of butterfly. There are a variety of rubber lining materials available, can be replaced.
The product is simple, the output torque, and superior performance. Control valve normally sealing requirements for high corrosive fluids.
