放料阀主要用于反应釜、储罐、和其他容器的底部排料、放料、取料和无死区关断操作。借助于阀门底部法兰焊接于储罐或其他容器的底部，因此消除工艺介质通常在容器出口的残留现象，放料阀根据实际需求，阀底结构设计为平底型，阀体结构为Y型，并提供提升或下降两种工作方式阀瓣。

密封副采用线密封，阀瓣密封根据需要可堆焊硬质合金，使表面硬度达到HRC56-62，具有高耐磨、耐腐蚀的功能，保证密封的可靠性。

The discharge valve is mainly used for bottom discharge, discharge, retrieval, and dead zone free shutdown operations of reactors, storage tanks, and other containers. By welding the bottom flange of the valve to the bottom of the storage tank or other containers, the residual phenomenon of process medium at the outlet of the container is eliminated. The discharge valve is designed with a flat bottom structure and a Y-shaped valve body structure according to actual needs, and provides two working modes of lifting or lowering the valve disc.
The sealing pair adopts a line seal, and the valve disc seal can be welded with hard alloy as needed to achieve a surface hardness of HRC56-62. It has high wear resistance and corrosion resistance, ensuring the reliability of the seal.
