Raw material belt is an auxiliary product commonly used in the installation of liquid pipelines, which is used at the connection of pipe fittings to enhance the tightness of pipe connections. Raw material belt is a new and ideal sealing material. Because of its non-toxic, tasteless, excellent sealing, insulation and corrosion resistance, it is widely used in priority areas such as water treatment, natural gas, chemical, plastic and electronic engineering, Remove the foreign matters at the connection part of the raw material belt; Wind inward along the outer edge of the pipe mouth.
Pay attention to the winding 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, so that the angle valve will be tightened more and more without loosening. Pay attention to the flatness of the raw material belt during the winding process to ensure that the silk mouth is completely wrapped by the raw material belt.
When winding, the raw material belt shall be tightened to make the raw material belt closely attach to the thread. Try to tighten the raw material belt as much as possible, and do not loosen it. After winding, it shall be tightened by hand in a circle or at the same time. Wrap for 2-3 turns, and the edge of the silk mouth is slightly thicker than the raw material belt inside the silk mouth.
As for the winding of "several layers", there is no hard and fast regulation, which is subject to screwing and no leakage. However, according to experience, it usually requires more than ten circles of winding to ensure the sealing effect. After winding, pinch it with the finger ring to make it fit with the silk mouth.
When screwing the thread, do not screw it in the way of death. It is not necessary to screw it to the point where it cannot be screwed, as long as it feels strong when screwing. In addition, pay attention to the depth of screwing in, such as the two bending feet of the hot and cold water mixing valve. When screwing, pay attention to maintaining the same distance from the wall, especially when the two inner wire elbows in the wall are not in the same depth. Hold the wrapped connector and screw it in place clockwise.
