　　真空旋转阀是真空系统里用于‌连续卸料并锁气保压‌的关键阀门，靠转子在阀体内旋转，把物料送入或送出真空容器，同时尽量减少外界空气漏进来。

　　真空旋转阀作用：

　　‌在真空下连续加料或排料‌：适合粉状、颗粒状物料在真空气力输送、除尘系统、反应釜加料等流程中使用。

　　保持系统真空稳定‌：通过阀内物料形成料封，减少空气从进料口进入真空腔，起到锁风、锁气作用。

　　常见场景‌：石化反应釜真空密闭加料、粉粒料输送、除尘与工艺配料系统。

　　真空旋转阀工作原理：

　　转子旋转送料‌：电机带动阀内转子连续旋转，物料从进料口落入转子格室，再被带出到排料口。

　　‌料封减少漏气‌：转子格室始终有部分被物料填满，形成物料密封层，降低真空侧与大气侧之间的空气泄漏。

　　‌特殊工况会加强密封‌：高真空或易积粉场合，阀体会设计通气接口、气体吹扫或双层耐压结构，防止物料卡滞和漏气增大。

　　通径和压力匹配‌：根据物料流量、系统真空度及压力波动选择合适通径和耐压等级。

　　Vacuum rotary valve is a key valve used in vacuum systems for continuous unloading and air locking and pressure maintenance. It relies on the rotor to rotate inside the valve body, sending materials into or out of the vacuum container while minimizing the leakage of external air.

　　Function of vacuum rotary valve:

　　Continuous feeding or discharging under vacuum: suitable for powder and granular materials in processes such as vacuum pneumatic conveying, dust removal systems, and reactor feeding.

　　Maintain system vacuum stability: By forming a material seal inside the valve, air is reduced from entering the vacuum chamber through the feed port, which plays a role in air locking.

　　Common scenarios: Vacuum sealed feeding of petrochemical reaction vessels, transportation of powder and granular materials, dust removal and process batching systems.

　　Working principle of vacuum rotary valve:

　　Rotating rotor feeding: The motor drives the rotor inside the valve to rotate continuously, and the material falls into the rotor compartment from the feeding port and is then carried out to the discharge port.

　　Material sealing reduces air leakage: The rotor compartment is always partially filled with material, forming a material sealing layer to reduce air leakage between the vacuum side and the atmospheric side.

　　Special working conditions will enhance sealing: in high vacuum or powder prone situations, the valve body is designed with ventilation interfaces, gas blowing, or double-layer pressure resistant structures to prevent material jamming and increased gas leakage.

　　Diameter and pressure matching: Select the appropriate diameter and pressure resistance level based on material flow rate, system vacuum degree, and pressure fluctuations.
