What are the precautions encountered during the opening of the stainless steel tee?

The swelling deformation of stainless steel tee is an elongation type deformation. When ε reaches a certain level, the material shrinks at the edge of the hole and then ruptures. Therefore, preventing the edge of the hole from cracking is the main problem of squeeze forming, and the ultimate deformation degree of one squeeze is mainly limited by the elongation of the stainless steel material. The precautions of the stainless steel three-way opening process are as follows: 1. The stainless steel three-way ball valve is in the blocking position, and the ball is impregnated by the mechanical pressure of the valve stem, and is tightly pressed on the valve seat. 2. When the hand wheel is moved counterclockwise, the valve stem of the stainless steel three-way ball valve acts in the opposite direction, and the angular plane at the bottom causes the ball to separate from the valve seat. 3. The valve stem is continuously drawn and immersed with the guide pin in the spiral groove of the valve stem, so that the ball starts to twist without friction. 4. Until it reaches the fully open position, the valve stem is drawn to the limit position, and the ball is twisted to the fully open position.
