Water pipe with synchronously retractable multi-layer
Abstract:
Disclosed is a water pipe with synchronously retractable multi-layer, comprising: a retractable inner pipe; a fabric sleeve sleeved outside the inner pipe, which is configured as a retractable cylindrical or corrugated one- or multi-layer fabric sleeve formed by interweaving retractable elastic yarns arranged at intervals in the axial direction and non-retractable reinforcing yarns arranged at intervals in the circumferential direction; and a retractable plastic film layer interposed between the inner pipe and the fabric sleeve. According to the present disclosure, the inner pipe, the plastic film layer and the fabric sleeve can be synchronously retracted under the effect of water pressure change, so that the frictional damage among multiple layers is effectively reduced, and the service life of the entire retractable water pipe is prolonged.
