Detailed Description
Referring to the attached drawings, the anti-lock structure for the valve seat of the ore pulp valve in the embodiment comprises the ore pulp valve and a framework pipeline, and the ore pulp valve is connected with the framework pipeline. The ore pulp valve has the valve body, the flashboard, the filler, gland and rubber seal disk seat, filler and flashboard cooperation, the gland is pressed and is established on the filler, be furnished with first fastener (for example bolt and nut) between gland and the valve body and be connected, the disk seat sets up on the runner hole of valve body, the whole circular pore that is in runner hole, rubber seal disk seat includes left seat and right seat, left seat and right seat support the cooperation mutually, the flashboard corresponds the lift activity between left seat and the right seat, flashboard and left seat and right seat seal cooperation, when the flashboard is closed, will descend and insert between left seat and the right seat, open then from ascending shifting out between left seat and the right seat.
The framework pipeline comprises a left pipe and a right pipe, and the left pipe and the right pipe are respectively in a circular pipe shape. The right end of the left pipe abuts against the left side of the valve body and forms a left limiting end face, namely the outer ring part of the right end of the left pipe abuts against the left side of the valve body, and the inner ring part of the right end of the left pipe blocks against the left side of the flow passage hole to form the left limiting end face; the left end of the right pipe abuts against the right side of the valve body and forms a right limit end face, namely the outer ring part of the left end of the right pipe abuts against the right side of the valve body, and the inner ring part of the left end of the right pipe abuts against the right side of the flow passage hole and forms the right limit end face; the left limit end face and the right limit end face are matched with the flow channel hole to form the mounting position of the rubber sealing valve seat, and the left seat and the right seat are located between the left limit end face and the right limit end face in the embodiment. The left seat and the right seat are in sealing fit between the left limit end face and the right limit end face.
