QJ(N/T)Z型氣動(dòng)偏心旋轉(zhuǎn)調(diào)節(jié)閥(或稱凸輪繞曲調(diào)節(jié)閥)由偏心旋轉(zhuǎn)閥，氣動(dòng)執(zhí)行機(jī)構(gòu)、閥門定位器、手輪機(jī)構(gòu)組成。

氣動(dòng)偏心旋轉(zhuǎn)調(diào)節(jié)閥產(chǎn)品信息

一、概述Outline

QJ（N/T）Z型氣動(dòng)偏心旋轉(zhuǎn)調(diào)節(jié)閥（或稱凸輪繞曲調(diào)節(jié)閥）由偏心旋轉(zhuǎn)閥，氣動(dòng)執(zhí)行機(jī)構(gòu)、閥門定位器、手輪機(jī)構(gòu)組成。
產(chǎn)品特點(diǎn)如下：

1.閥座磨損小，使用壽命長(zhǎng)：球面閥芯回旋中心不與閥桿旋轉(zhuǎn)軸同心，可減少閥座磨損，延長(zhǎng)控制閥壽命；

2.泄漏量?。洪y芯和閥座關(guān)閉時(shí)，閥芯繞臂在執(zhí)行機(jī)構(gòu)推力作用下產(chǎn)生微小彈性變形及彈性漲緊力，使閥芯與閥座更加緊密牢固，大大地減小泄漏量；

3.執(zhí)行機(jī)構(gòu)所需扭矩比球閥，蝶閥的?。涸摦a(chǎn)品綜合了單座閥、球閥、蝶閥等控制閥的優(yōu)點(diǎn)，具有閥體流路簡(jiǎn)單，流阻小、額定流量系數(shù)大，可調(diào)比大、泄漏量小，密封性能好及體積小，重量輕等特點(diǎn)，可廣泛應(yīng)用于石油石化，冶金，醫(yī)藥等行業(yè)的控制系統(tǒng)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、結(jié)構(gòu)原理Structure principle

氣動(dòng)偏心旋轉(zhuǎn)閥閥芯，閥桿作旋轉(zhuǎn)運(yùn)動(dòng)，所以調(diào)節(jié)閥在工作過程中所受摩擦力很小，當(dāng)閥芯和閥座相接觸關(guān)閉時(shí)，閥芯繞臂在執(zhí)行機(jī)構(gòu)推力作用下產(chǎn)生微小彈性變形及彈性漲緊力，使閥芯與閥座接觸更加緊密牢固，因此偏心旋轉(zhuǎn)閥泄漏量很小。同時(shí)關(guān)閉閥門所需的執(zhí)行機(jī)構(gòu)推力與球閥、蝶閥相比要小。另外在閥芯與上，下導(dǎo)向之間留有一定的間隙以確保閥芯能自動(dòng)對(duì)中。
在偏心旋轉(zhuǎn)閥產(chǎn)品中，省去了閥蓋這一單獨(dú)零件，閥蓋與閥體鑄成一體，由于閥蓋較長(zhǎng)，有足夠的散熱面積，故偏心旋轉(zhuǎn)閥的使用溫度為-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 ℃.
