Raw material tape (chemical name is polytetrafluoroethylene) is a commonly used auxiliary equipment in water heating installation, used for pipe fittings connection, to enhance the sealing of pipe joints. Raw meal belt is a novel and ideal sealing material. Because of its non-toxic, tasteless, excellent sealing, insulation, corrosion resistance, it is widely used in water treatment, natural gas, chemical, plastic, Electronic Engineering and other fields.
In our daily life, we sometimes install angle valves, taps, pipes, etc. by ourselves. When we wrap the raw material tape, it always doesn't wrap well. The tap always leaks and seeps. What's the matter? How can we wrap the raw material tape?
1. Clean up the foreign body in the connecting part of the raw material belt first, and then wind it inward along the outer edge of the pipe opening.
2. Pay attention to the direction of winding. Take the angle valve as an example. When the angle valve is screwed into the wall, it rotates clockwise to the right. Then we wrap the raw material belt on the angle valve in the direction of counterclockwise to the left. In this way, the tighter the angle valve is, and it will not loose. Attention should be paid to the raw material strip formation during the winding process to ensure that the silk thread is completely wrapped by the raw material belt.
3. When wrapping, tighten the raw material belt, so that the raw material belt tightly attached to the thread, as tight as possible, do not loosen the wrapping, wrapped with a hand to tighten the circle, you can also tighten while wrapping. Wrap around 2-3 circles. After finishing, the edge of the wire edge is slightly thicker than that of the inner side of the silk mouth.
4. As for winding "several layers" without rigid provisions, to be able to tighten, no leakage as the standard, but according to experience, usually need to winding more than a dozen circles to ensure sealing effect. When the winding is finished, use the finger ring to pinch it, so that it fits perfectly with the silk thread.
5. When screwing a thread, do not screw it to death. It does not necessarily have to be screwed to the point where it can't be screwed. In addition, attention should be paid to the depth of the screw in, such as hot and cold water mixing valve two bending feet against the wire, when screwing, attention should be paid to maintaining the same distance from the wall, especially in the wall of the two internal wire bend depth is not consistent. Hold the wrapped connector and turn it in clockwise direction.
In order to avoid leakage and seepage at the pipe interface, besides mastering the correct winding method of raw material belt, and using the reliable raw material belt, the raw material belt of Beibei whale is worth purchasing and using safely.
