一、概述/ Summary：

氣動偏心旋轉調節閥（也稱“凸輪撓曲閥”），由氣動執行機構和偏心旋轉閥及定位器等附件組配而成。它充分利用了閥內件的偏心旋轉之特點，讓流道更通暢，且自清潔能力大幅提升。對閥座、旋轉閥芯或閥內腔的特殊硬化處理，提升了其抗腐蝕和顆粒高速沖刷的性能，非常適合煤氣化等工藝系統中，用于控制水煤漿、黑灰水、渣水及油漿等含顆粒狀介質的調節和控制。

Pneumatic eccentric rotary control valve (also called "cam deflection valve") is composed of pneumatic actuator, eccentric rotary valve, positioner and other accessories. It makes full use of the eccentric rotation of the valve trim, which makes the flow channel smoother and greatly improves the self-cleaning ability. The special hardening treatment of the valve seat, rotary valve core or valve cavity improves its corrosion resistance and high-speed particle erosion performance. It is very suitable for coal gasification and other process systems to control coal water slurry, black ash water, and slag water. Adjustment and control of granular media such as oil slurry.

二、結構和材質/ Structure And Material：

三、特點/ Characteristic：

1、閥體流道近似管道，流阻小，流通能力強，可調節范圍廣；

2、閥芯偏心旋轉設計，閥芯開啟時能夠迅速脫離閥座，從而減少對密封面的摩擦。開啟后

閥芯隱藏在流道后側，較好避免了介質對密封面的沖刷；

3、閥芯與閥座有相對剪切作用，自清潔能力強。

4、閥門長頸設計，適用于溫度范圍廣泛；

5、結構簡單，重量輕，安裝維護方便。

1. The flow path of the valve body is similar to the pipeline, with small flow resistance, strong flow capacity and wide adjustable range;

2. The valve core is designed with eccentric rotation, and the valve core can be quickly separated from the valve seat after opening, thereby reducing the friction on the sealing surface. After opening, the valve core is hidden behind the flow channel, which better avoids the erosion of the sealing surface by the medium;

3. The valve core and the valve seat have a relative shearing effect, and the self-cleaning function is strong.

4. The valve has a long neck design, which is suitable for a wide temperature range;

5. Simple structure, light weight, convenient installation and maintenance.
