I. Overview of Upward Discharging Valve
 
      主要用于反应器,储罐和其它容器的底部排料,借助于阀门底部法兰焊接于储罐和其它容器的底部,因此消除工艺介质通常在容器出口的残留现象 The up-spray discharge valve is mainly used for the bottom discharge of reactors, storage tanks and other containers. The bottom flange of the valve is welded to the bottom of storage tanks and other containers, so the residual phenomenon of process media usually at the outlet of the container is eliminated . 阀根据实际情况的需要,放底结构设计为平底型,阀体为V型,并提供提升和下降两种工作方式阀瓣。 The push-down discharge valve is designed with a flat bottom type and a V-shaped valve body according to the needs of the actual situation. The valve disc is provided in two working modes: lifting and lowering. The inner cavity of the valve is equipped with a erosion-resistant and corrosion-resistant seal ring. When the valve is opened, it can protect the valve body from being washed away and corroded by the medium. The seal ring is specially treated to make the surface hardness reach HRC56 ~ 62, which has high wear resistance. , Corrosion resistance. The valve flap seal is hard alloy welded on the cover as required, and the sealing pair adopts wire seal to ensure the reliability of the seal and prevent scarring. At the same time, a short-stroke disc design is adopted. Widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dye, food processing and other industries. Various operation modes, such as manual, pneumatic (spring return, double acting, with and without handwheel), electric, hydraulic, gear, etc.
