Further, the guide sleeve comprises a cover plate and a guide rod, the cover plate is positioned in the connecting sleeve and is pressed by a coating cylinder connected with the connecting sleeve, and the cover plate is used for preventing the valve ball from being sucked into the coating cylinder; the guide rods are fixedly connected below the cover plate and uniformly arranged along the circumferential direction of the valve ball and used for guiding the valve ball to move up and down.
Further, the cover plate is in a three-fork shape or a cross shape.
Further, the upper end of disk seat is provided with the valve seat circle, the valve ball place in on the valve seat circle, the valve seat circle is the high strength alloy cover.
Furthermore, a sealing ring I is arranged between the valve seat and the connecting sleeve.
Further, the elbow and the connecting sleeve are arranged between the sealing ring II.
Further, the valve ball is a ceramic ball.
The utility model discloses beneficial effect:
in the utility model, the valve seat ring, the valve ball and the guide sleeve are all positioned inside the connecting sleeve, thereby effectively reducing the size of the material suction valve in the height direction and further reducing the overall height of the spraying machine; in addition, the elbow of the utility model is connected with the connecting sleeve through the quick-connecting chuck, and only the quick-connecting chuck needs to be disassembled without rotating the elbow during disassembly, thereby being convenient to operate; finally, the valve seat can be downwards removed after the elbow is removed, and the valve ball is taken out at the same time, so that the connecting sleeve is not required to be integrally removed, and the operation is simplified.
