The utility model discloses a zinc alloy deep slagging device, which relates to the technical field of zinc alloy process and comprises a supporting rod, a sleeve is rotatably arranged on the lower surface of the supporting rod, a supporting column is inserted into the lower end of the sleeve, a transverse plate is fixedly arranged at the lower end of the supporting column, and one side of the lower surface of the transverse plate is fixedly connected with a mounting cover. A feeding barrel is detachably arranged on the lower surface of the installation cover, a plurality of exchange holes are formed in the outer surface of the feeding barrel, and a plurality of bolt grooves which are distributed at equal intervals in the vertical direction are formed in the outer surface of the supporting column and the outer surface of the sleeve. A transmission structure design enables an operator to easily control the rotation of the charging barrel by rotating a handle, so that the labor intensity is reduced and the working efficiency is improved; the supporting columns and the sleeves are matched with positioning bolts and other structures, the position of the feeding barrel can be conveniently adjusted according to the depth of the smelting furnace and production requirements, various working conditions are adapted, and diversified slagging requirements are met.

This utility model discloses a fixed forged steel ball valve, relating to the field of ball valve technology. The utility model includes a base plate, on the upper surface of which a force-saving mechanism is fixedly mounted. Multiple fixed mechanisms arranged in a rectangular array are inserted into the upper surface of the base plate. Each force-saving mechanism includes a valve frame, the lower surface of which is fixedly connected to the base plate. A positioning rod is fixedly mounted on the upper surface of the valve frame, a pull rod is sleeved on the outer side of the positioning rod, a rotating ring slides on the outer side of the pull rod, a rotating plate is fixedly mounted on the outer side of the rotating ring, and a rotating rod is fixedly mounted on the lower surface of the rotating plate. This utility model, through its force-saving mechanism, allows for easy control of the ball valve core's rotation via the sliding operation of the pull rod and rotating ring, thereby simplifying the opening and closing operation of the ball valve and improving its convenience and efficiency. Simultaneously, the valve groove inside the valve frame and the sealing rings on both sides ensure the stability and sealing of the ball valve core's rotation.
