Transformer Control Cooling Oil Butterfly Valve



Product Overview

  The butterfly valve is mainly composed of a valve piece, a cast aluminum valve body and a rotating shaft, and is characterized in that the top end of the rotating shaft has a trigger. The butterfly valve body has a blind pit on the front side to reduce the weight. To ensure the strength, the reinforcing rib is placed to ensure the strength and flatness. The trigger sleeve is fixed at the top of the rotating shaft, and can be operated by hand. The trigger is marked with opening and closing marks to avoid the possibility of misoperation; the top of the trigger is provided with the opening and closing position of the pit, and the spring steel ball phase Top, when the operator pulls the trigger, when it reaches the open and closed positions, it will produce a sense of position.

  Figure 1 is a front view of the butterfly valve,

  Figure 2 is a cross-sectional view taken along line A-A of Figure 1.

  Figure 3 is a plan view of Figure 1.

  In the figure: 1 valve body, 2 springs, 3 steel balls, 4 triggers, 5 shafts, 6 riveting pins, 7 blind pits, 8 ribs, 9 sealing rings, 10 sealing rings, 11 valve plates, 12 riveting pins.

  The valve body 1 is formed by die-casting of aluminum alloy, and four blind pits 7 are formed at respective positions on the front and back sides, and an annular reinforcing rib 8 is formed. The valve body 1 is provided with a rotating shaft 5, and the shaft body is fixedly connected to the valve plate 11 by the rivet pin 12. When the rotating shaft rotates, the valve piece 7 can be rotated to form an opening and a closing. The top end of the rotating shaft 5 is fixed to the trigger 4 through the rivet pin 6 to apply a torque to the rotating shaft 4. A flange is formed on the valve body 1 adjacent to the trigger 4, and a coil spring 2 and a steel ball 3 are mounted in the through hole, and the steel ball 3 is overlapped with the end surface of the trigger 4 and is clamped at 90° to the end surface. The two corners of the corner corresponding to the open and closed positions (not shown) are concave-convex, to locate and produce a positioning feel. The upper end of the trigger 4 is marked with "on" and "off" marks, and the operation is clearer and more accurate.
