The raw material belt shall be wound along the thread direction without reverse direction. Take the angle valve as an example. When the angle valve is screwed into the internal thread of the wall, it rotates clockwise to the right. Then we wind the residual tape on the angle valve counterclockwise to the left. In this way, the angle valve will be tightened more and more without loosening.
Strong and close
When winding, we should tighten the raw material belt, so that the raw material belt is closely attached to the thread. Try to tighten it as much as possible, and do not loosen it to prevent it from loosening. In order to maintain a certain degree of tightness, it is necessary to press it by hand in a circle after winding, or it can be pressed and wound at the same time. After winding for several circles, pinch it with a finger ring to make it fit with the silk mouth, so as to achieve effective sealing.
