ANTI-FREEZING PIPELINE ATTACHED MECHANISM FOR PREVENTING THE FREEZING WITHOUT DISCHARGING WATER OF PIPELINES IN MIDWINTER

摘要

PURPOSE: An anti-freezing pipeline attached mechanism is provided to prevent the freezing without discharging water from a water pump, a heating pipeline and a pipeline for connecting with a cooling spring cooler, etc. in winter or vacation time, to promote work efficiency by reducing the time required for discharging and filling water and to have the effect on safety by protecting high-priced components, equipment, etc. CONSTITUTION: A pipeline is installed through the steps of perforating many holes(2) on a pipe(1) installed to a part which is exposed to the outside or easy to be frozen, fixing a nut connection(4) having fastening threads(3) to the hole(2) by a welding unit(5) and installing an anti-freezing attached mechanism(6) to the nut connection(4) at regular intervals. The anti-freezing attached mechanism(6) comprises the steps of fastening a case(7) and a cap(11), forming fastening threads(13,14) on the upper and lower ends of the case(7), inserting a lifting stopper(8) fixed with rubber O-rings(10,10') to retreated grooves(9,9') in the case(7), then installing a spring(15) to bear the appointed pressure, fastening a cap(11) having a fastening thread(12) with a fastening thread(13) of the case(7), and fastening a fastening thread(14) of a case(7) to a nut connection(4) of a pipe(1). If the water in the pipe(1) froze, the lifting stopper(8) of the anti-freezing attached mechanism(6) lifts up to form a space which houses and regulates the increased volume caused by frozen pipe to prevent the weak part of the pipe(1) or a water pump from freezing to house and adjust the expanded volume.
