Ptfe tape is an auxiliary product commonly used in the installation of liquid pipelines, which is used at the joints of pipe fittings to enhance the closeness of the joints of pipelines. Raw material belt is a novel and ideal sealing material. Due to its non-toxic, tasteless, excellent sealing, insulation and corrosion resistance, it is widely used in water treatment, natural gas, chemical industry, plastics, electronic engineering and other fields. First of all, clean up the foreign matter in the connection part of the raw material belt; Twine inward along the outer edge of the pipe wire.
Pay attention to the winding direction. Take the angle valve as an example. When the angle valve is screwed into the inner thread of the wall, it rotates clockwise to the right. Then we wrap the leftover material belt on the angle valve in the direction of counterclockwise to the left, in this way, the angle valve will be tighter and tighter when screwed, and will not loosen. During the winding process, pay attention to the smoothness of the raw material belt to ensure that the screw opening is completely wrapped by the raw material belt.
When wrapping, tighten the raw material belt, and make the raw material belt tightly attached to the thread. Try to tighten it as much as possible. Don't wrap it loose. After wrapping, press it with a hand circle, or wrap it while pressing. Winding for 2-3 times, after completion, the edge of the wire mouth is slightly thicker than the raw material belt inside the wire mouth.
As for the winding "several layers", there is no hard regulation, which is subject to the tightness and no leakage. However, according to experience, it usually needs to be wound for more than ten times to ensure the sealing effect. After the winding is completed, pinch it with a finger ring to make it fit perfectly with the screw opening.
