QJ(N/T)Z型气动偏心旋转调节阀(或称凸轮绕曲调节阀)由偏心旋转阀，气动执行机构、阀门定位器、手轮机构组成。

气动偏心旋转调节阀产品信息

一、概述Outline

QJ（N/T）Z型气动偏心旋转调节阀（或称凸轮绕曲调节阀）由偏心旋转阀，气动执行机构、阀门定位器、手轮机构组成。
产品特点如下：

1.阀座磨损小，使用寿命长：球面阀芯回旋中心不与阀杆旋转轴同心，可减少阀座磨损，延长控制阀寿命；

2.泄漏量小：阀芯和阀座关闭时，阀芯绕臂在执行机构推力作用下产生微小弹性变形及弹性涨紧力，使阀芯与阀座更加紧密牢固，大大地减小泄漏量；

3.执行机构所需扭矩比球阀，蝶阀的小：该产品综合了单座阀、球阀、蝶阀等控制阀的优点，具有阀体流路简单，流阻小、额定流量系数大，可调比大、泄漏量小，密封性能好及体积小，重量轻等特点，可广泛应用于石油石化，冶金，医药等行业的控制系统中。

QJ （N / T） Z-type pneumatic rotary valve eccentric （or cam flexing valve） by the eccentric rotary valve, pneumatic actuator, positioner, handwheel agencies.
Product features are as follows:

1 seat wear, long life: the spherical valve swing center is not concentric with the stem axis of rotation, can reduce seat wear and extend the life of the control valve;

（2） a small amount of leakage: the valve core and valve seat is closed, the actuator arm around the spool under the action of small thrust elastic deformation and elastic tensioning force, the valve core and valve seat even more tightly and securely, greatly reducing the amount of leakage ;

3 more than the required torque actuator ball valve, butterfly small: The product combines the single-seat valves, ball valves, butterfly valves and other control benefits, with the valve flow path is simple, small flow resistance, nominal flow coefficient large, adjustable ratio, a small amount of leakage, sealing performance and small size, light weight, can be widely used in petrochemical, metallurgical, pharmaceutical and other industry control systems.

二、结构原理Structure principle

气动偏心旋转阀阀芯，阀杆作旋转运动，所以调节阀在工作过程中所受摩擦力很小，当阀芯和阀座相接触关闭时，阀芯绕臂在执行机构推力作用下产生微小弹性变形及弹性涨紧力，使阀芯与阀座接触更加紧密牢固，因此偏心旋转阀泄漏量很小。同时关闭阀门所需的执行机构推力与球阀、蝶阀相比要小。另外在阀芯与上，下导向之间留有一定的间隙以确保阀芯能自动对中。
在偏心旋转阀产品中，省去了阀盖这一单独零件，阀盖与阀体铸成一体，由于阀盖较长，有足够的散热面积，故偏心旋转阀的使用温度为-40~+350℃。

Eccentric rotary valve pneumatic valve, valve stem for rotation, so valve suffered in the course of friction is very small, when the spool and the valve seat in contact is closed, the actuator arm around the spool under the action of small thrust elastic deformation and elastic tensioning force, the valve with the valve seat even more tightly and securely, so the eccentric rotary valve leakage is very small. At the same time required to close the valve actuator thrust and ball valves, butterfly small compared to. Also in the spool and the upper and lower guide leave enough space between to ensure that the valve can automatically.
In the eccentric rotary valve products, eliminating the need for separate parts of the valve cover, valve cover and valve body cast one, as long bonnet, there is sufficient cooling area, so the eccentric rotary valve operating temperature of -40 ~ + 350 ℃.
