Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 5 As shown, the explosion-proof membrane valve assembly for the powder-making pipeline includes a main powder-air pipeline 1 and a branch powder-air pipeline 2 on the surface of the main powder-air pipeline 1. A slide gate valve 3 is fixedly installed on the end face of the branch powder-air pipeline 2, and a connecting pipe 4 is fixedly installed on the end face of the slide gate valve 3. An explosion-proof membrane 5 is fixedly installed on the end face of the connecting pipe 4. More specifically, the slide gate valve 3 is fixedly installed at the end of the branch powder-air pipeline 2 by bolts, and the connecting pipe 4 is fixedly installed to the other end of the slide gate valve 3 by bolts. The explosion-proof membrane 5 is fixed to the end face of the connecting pipe 4. When the powder is conveyed in the main powder-air pipeline 1, the slide gate valve 3 is in an open state. When it is necessary to replace or remove the explosion-proof membrane 5 at the end of the connecting pipe 4, the slide gate valve 3 seals the end of the branch powder-air pipeline 2, thereby ensuring that the powder conveying in the main powder-air pipeline 1 is not stopped, and the explosion-proof membrane 5 at the end of the connecting pipe 4 can be replaced.

[0024] The slide gate valve 3 includes a valve body 301 fixedly installed on the end face of the air-powder branch pipe 2. A housing 302 is fixedly installed on the surface of the valve body 301, and grooves 303 are formed on the inner walls of the valve body 301 and the housing 302. A U-shaped frame 304 is fixedly installed on the surface of the housing 302, and an adjusting nut 305 is rotatably installed on the bottom inner side of the U-shaped frame 304. A threaded rod 306 is threadedly inserted into the surface of the adjusting nut 305, and the threaded rod 306 and the U-shaped frame 304 are movably inserted into each other. A connecting frame 307 is rotatably installed at the end of the threaded rod 306, and a slide plate 308 is fixedly installed at the end of the connecting frame 307. More specifically, by rotating the adjusting nut 305, the threaded rod 306 and the adjusting nut 305 are threadedly connected, thereby enabling the slide plate 308 to move vertically within the groove 303 on the inner wall of the valve body 301 and the housing 302. The slide plate 308 moves vertically downward, thereby opening the interior of the valve body 301. The slide plate 308 moves vertically upward, thereby sealing the interior of the valve body 301, making it convenient to disassemble and replace the explosion-proof membrane 5.

[0025] The end of the plug-in plate 308 is arc-shaped, and the plug-in plate 308 is movably inserted into the groove 303. More specifically, the end of the plug-in plate 308 is arc-shaped, so that after being inserted into the groove 303 of the inner wall of the valve body 301, leakage of the powder flowing in the main powder pipeline 1 is avoided.

[0026] A threaded column is arranged at the top end of the plug-in plate 308, and the threaded column at the top end of the plug-in plate 308 is inserted into the connecting frame 307, and the connecting frame 307 and the plug-in plate 308 are fixedly connected through a fixing nut. More specifically, the threaded column at the top end of the plug-in plate 308 is screwed with a threaded sleeve through a fixing bolt, so as to realize the fixed connection of the plug-in plate 308 and the connecting frame 307.

[0027] The width of the groove 303 is equal to the thickness of the plug-in plate 308, and the plug-in plate 308 is inserted into the groove 303 to block the end of the branch powder pipeline 2. More specifically, the width of the groove 303 is equal to the thickness of the plug-in plate 308, so that the inside of the valve body 301 can be sealed and blocked after the plug-in plate 308 is inserted.

[0028] In summary, the plug-in valve 3 is fixedly installed at the end of the branch powder pipeline 2 through a bolt, and the connecting pipeline 4 is fixedly installed at the other end of the plug-in valve 3 through a bolt, wherein the explosion-proof membrane 5 is fixed at the end face of the connecting pipeline 4. When the explosion-proof membrane 5 at the end of the connecting pipeline 4 needs to be replaced and disassembled, the end of the branch powder pipeline 2 is sealed through the plug-in valve 3, so that the powder conveying in the main powder pipeline 1 is not stopped, and the explosion-proof membrane 5 at the end of the connecting pipeline 4 is replaced.
