In order to achieve the aim, the utility model provides an automatic discharging butterfly valve which comprises a valve body, a butterfly plate and a valve rod, wherein the butterfly plate is rotatably arranged on the valve body, the valve rod is connected with the butterfly plate, one side of the valve body is fixedly provided with a connecting pipe, the valve rod is rotatably arranged in an inner hole of the connecting pipe, one end of the valve rod penetrates through the inner hole of the connecting pipe and is fixed with a transmission connecting block, a limiting groove is arranged on the transmission connecting block, a mounting seat is fixed at one end of the connecting pipe, a limiting block is rotatably arranged on the mounting seat and can be inserted into or separated from the limiting groove through rotation, so as to cooperate with limiting or releasing the rotation of the transmission connecting block, an elastic component for the limiting block to move towards the direction of inserting into the limiting groove is arranged between the limiting block and the mounting seat, when the butterfly valve is in a closed state, the limiting groove of the transmission connecting block is in a position corresponding to the limiting block.
Furthermore, the end of the transmission connecting block is flat and at least comprises two opposite, parallel and flat end faces.
Furthermore, the elastic component is a tension spring, one side of the limiting block corresponding to one side of the mounting seat is provided with a pin, and the tension spring is respectively hooked on the pin of the limiting block and the pin of the mounting seat.
Furthermore, the transmission connecting block is inserted into one end of the valve rod and fixed through a pin axially penetrating through the transmission connecting block.
Furthermore, one side of the limiting block corresponding to the limiting groove comprises a first guiding inclined plane and a second guiding inclined plane respectively.
The utility model has the beneficial effects that: the transmission connecting block can be conveniently connected with an external power source (such as a motor) in a transmission way, so that the material discharging butterfly valve can be ensured to have lower weight; in addition, the self-locking of the butterfly valve can be realized through the matching among the limiting blocks, the limiting grooves and the limiting members, so that the valve rod can be locked when the butterfly valve is in a closed state, the butterfly valve is prevented from being opened by self, and the butterfly valve is more reliable to use.
