Water intake pipes emptying and antifreeze method and apparatus

Abstract

The invention discloses a method and fixture of up-hose emptier. It mainly makes use of the theory that two medium of different gravity, which the lighter is always on the top in the same container. A sealed trunk for exchange of water and stream is fixed on the bottom of up-hose. The water is discharged from hose by exchange. According to the method ,the device is composed of trunk 1,tie-in 2 in the upside of trunk 1,tie-in 3 in the downside of trunk1,switch 4 and valve 7 n the tie-in 2,switch 5 and valve 6 on the tie-in 3.The kind of device is of preventing frostbite well, good effect, applying widely, convenience in the constriction ,maintain and using, low cost, small equipment, long use, without pollution ,especially using in solar water heater .

Description

technical field [0001] The invention belongs to a water pipe antifreeze method and an antifreeze device, in particular to an upper water pipe emptying antifreeze method and an upper water pipe emptying antifreeze device. Background technique [0002] In daily life, the upper and lower water pipes are commonly used to raise the water level, such as solar water heaters. Most solar water heaters need to be placed on the roof or roof, connected to the water pipes with the upper water pipes, and the water pipes must be installed at the same time, or use a The water pipe is used as the upper and lower water pipe (that is, the same pipe is used for lifting water and lowering the water), and another example is a water tower or a water storage tank installed on the roof or roof, and it is also connected to the tap water pipe or water lifting equipment through the upper and lower water pipes , The upper and lower water pipes exposed to the outside have the problem...

AI Technical Summary

Problems solved by technology

At present, the antifreeze measures adopted are divided into four types: one is heat preservation measures, and the upper and lower water pipes are wrapped with heat preservation materials. ℃, it often cannot prevent the upper and lower water pipes from freezing and cracking; the second is the heating measure, by binding the heating material on the upper and lower water pipes to heat up the temperature of the pipe body, so as to avoid the freezing of the water in the pipe body. This kind of measure requires special equipment for heating, so it increases the use fee, so it is generally not used; the third is the measure of combining heat preservation and heating, although it has a better effect, but the use cost is high; The method of discharge, this method is naturally very effective, because there is no water to freeze, but it is limited to the water storage equipment with low water level at present, and the effective measures for discharging water to prevent freezing for the upper and lower water pipes of the high water level water tank have not yet been reported.
