背景技术 Background technique
溜槽闸阀具有结构简单、开启灵活的特点，其在氧化铝生产工艺过程中的分解、沉降等工序中大量的使用。而目前常用的溜槽闸阀多采用焊接结构，其将密封套直接固定在闸板上，从而使闸板与框体间形成软密封。此种结构使密封条固定在闸板上，在阀门开关过程中，密封条一直与框体接触，开启关闭阀门力矩较大，操作费力，且密封条易磨损拉伤，其次在焊接外框变形的情况下，极易导致密封不严而产生流料，并且固定密封条的螺栓在闸板开关过程中易出现与导向槽接触卡死的现象，影响整个生产的正常运行。 The chute gate valve has the characteristics of simple structure and flexible opening. It is widely used in the decomposition and settlement of alumina production process. At present, the commonly used chute gate valves mostly adopt welding structure, which directly fixes the sealing sleeve on the gate plate, so that a soft seal is formed between the gate plate and the frame. With this structure, the sealing strip is fixed on the gate plate. During the process of valve opening and closing, the sealing strip is always in contact with the frame body. The torque to open and close the valve is large, and the operation is laborious, and the sealing strip is easy to wear and tear. Secondly, the welding outer frame is deformed. Under the circumstances, it is very easy to cause leakage due to lax sealing, and the bolts fixing the sealing strip are prone to be stuck in contact with the guide groove during the gate opening and closing process, which affects the normal operation of the entire production.
