    簡單介紹:
    QJ(N/T)Z型氣動調節閥,氣動偏心旋轉調節閥(或稱凸輪繞曲調節閥)由偏心旋轉閥,氣動執行機構、閥門定位器、手輪機構組成。
    詳情介紹:

    一、氣動調節閥,氣動偏心旋轉調節閥概述Outline

    QJ(N/T)Z型氣動偏心旋轉調節閥(或稱凸輪繞曲調節閥)由偏心旋轉閥,氣動執行機構、閥門定位器、手輪機構組成。
    產品特點如下:

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

    2.泄漏量?。洪y芯和閥座關閉時,閥芯繞臂在執行機構推力作用下產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.執行機構所需扭矩比球閥,蝶閥的?。涸摦a品綜合了單座閥、球閥、蝶閥等控制閥的優點,具有閥體流路簡單,流阻小、額定流量系數大,可調比大、泄漏量小,密封性能好及體積小,重量輕等特點,可廣泛應用于石油石化,冶金,醫藥等行業的控制系統中。

    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、氣動調節閥,氣動偏心旋轉調節閥結構原理Structure principle

    氣動偏心旋轉閥閥芯,閥桿作旋轉運動,所以調節閥在工作過程中所受摩擦力很小,當閥芯和閥座相接觸關閉時,閥芯繞臂在執行機構推力作用下產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,因此偏心旋轉閥泄漏量很小。同時關閉閥門所需的執行機構推力與球閥、蝶閥相比要小。另外在閥芯與上,下導向之間留有一定的間隙以確保閥芯能自動對中。
    在偏心旋轉閥產品中,省去了閥蓋這一單獨零件,閥蓋與閥體鑄成一體,由于閥蓋較長,有足夠的散熱面積,故偏心旋轉閥的使用溫度為-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 ℃.
