Referring to fig. 1-3, an embodiment of the present utility model is provided: a pneumatic inclined kettle bottom valve comprises a valve body 1 and a ball 9 arranged in the valve body 1; a cover plate 3 is further arranged outside the valve body 1, and a connecting part 13 is further arranged between the cover plate 3 and the valve body 1; the connecting part 13 is clamped between the valve body 1 and the cover plate 3 by the fastener 2 penetrating through the valve body 1 and then being connected with the cover plate 3; the valve body 1 is also provided with a packing gland 6 and a valve rod 11, and the valve rod 11 is connected with the ball 9 through a connecting end 8; the valve body 1 is also provided with a driving piece 4, and the driving piece 4 is connected with the valve rod 11 through a connecting piece 5.

In summary, since the driving member 4 is directly arranged on the valve body 1 in an inclined manner, and the central axis of the connecting position of the driving member 4 is inclined with the central axis of the medium inlet and outlet on the valve body, the whole volume of the device is reduced, the installation and the disassembly of the driving member 4 are convenient, the structure of the valve body is simplified, and the production and the manufacturing cost of the device are reduced;

further, the fastening piece 2 penetrates through the valve body 1 and then is connected with the cover plate 3 so as to clamp the connecting part 13 between the valve body 1 and the cover plate 3, so that the sealing performance between the ball 9 and the connecting part 13 is better; meanwhile, when the driving piece 4 is electric or pneumatic equipment, the valve can be automatically opened and closed, the connecting piece 5 is connected with the valve rod 11, and the driving piece 4 and the valve rod 11 are convenient to assemble and disassemble, so that the equipment is simple and convenient to maintain, and the packing gland 6 is convenient to separate from the valve body 1 after the connecting piece is disassembled, so that the packing is convenient to replace.

Since the valve rod 11 is further provided with the annular groove 7 for installing the sealing ring, the joint of the valve rod 11 and the valve body 1 can be sealed by the sealing ring in the annular groove 7.

Further, since the connecting member 5 is a screw, and the connecting member 5 is connected to the nut 10 disposed inside the valve rod 11 after passing through the valve rod 11, the connection cost between the valve rod 11 and the connecting member 5 and the connection process between the valve rod 11 and the connecting member 5 can be further simplified.
