  The extrusion-expansion deformation of stainless steel tee belongs to elongation deformation. When the E is large enough, the material will shrink at the edge of the hole and then crack. Therefore, preventing the hole edge cracking is the main problem of extrusion bulging, and the ultimate deformation degree of one-time bulging is mainly limited by the elongation of stainless steel tee.

  The matters needing attention in the process of stainless steel tee opening are as follows:

  1. Stainless steel tee in the blockade position, the ball by the mechanical pressure of the stem immersion, pressure on the seat.

  2. When the hand wheel is moved counterclockwise, the stem of the stainless steel tee valve acts in the opposite direction, and its bottom angular plane causes the ball to detach from the seat.

  3. The stem is continuously drawn and impregnated with the guide pin in the spiral groove of the stem, so that the ball can be twisted without friction at the beginning.

  4. until the full opening position, the stem is drawn to the limit position and the sphere is turned to the full open position.
