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.

Embodiment 1

[0016]Embodiment 1 is made with reference to FIG. 1 . An upper water pipe emptying device is characterized in that the device is composed of a box body 1, an upper water pipe joint 2 on the upper side of the box body 1, and an upper water pipe joint 3 on the lower side of the box body 1, and the upper water pipe joint on the upper side of the box body 1 The joint 2 is provided with an air-water exchange switch 4 and an air intake valve 7, and a cut-off switch 5 and a drain valve 6 are arranged on the upper water pipe joint 3 on the lower side of the box body 1. When in use, the upper water pipe joint on the upper side of the box body 1 2. Connect with the lower port of the upper water pipe 2' on the upper side of the box body 1, the upper water pipe joint 3 on the lower side of the box body 1 is connected with the tap water pipe 3' or the water inlet equipment, and the outer nozzle of the drain valve 6 is connected with the drain pipe to drain water. The pipe is externally con...

Embodiment 2

[0018] Referring to Figure 2, Figure 2A, Figure 2B, and Figure 2C, Example 2 is produced. Figure 2 shows an embodiment of integrating valves or switches on the device. The anti-freezing device for emptying the upper water pipe is composed of a rotating core shell 8, a rotating core 9 and a box body 1. The box body 1 is fixed on the rear end of the rotating core shell 8, and the rotating core 9 is installed in the rotating core shell 8 and tightly fitted. Tight, will not produce water leakage, can be made of ceramic materials or plastics, four through holes are arranged along the same cross section on the rotating core shell 8, and the position corresponding to the upper water pipe joint directly above is the upper water pipe through hole 10 , marked as the upper water level A, starting from the marked upper water level A, turn 45 degrees clockwise to set the air intake through hole 11, the position directly below and corresponding to the drain pipe joint is the drainage throug...

Embodiment 3

[0020] Embodiment 3 is made with reference to FIG. 3 . The described upper water pipe emptying antifreeze device can also be connected to the side of the main pipe 2 "of the upper water pipe 2' in parallel as shown in Figure 3. The structure of the device is as shown in Figure 1. This connection method can Two valves 15, 16 need to be established on the pipeline 2 ".

[0021] The upper water pipe 2' may include a vertical upper water pipe and an inclined upper water pipe. During installation, care should be taken that the upper water pipe in the inclined section must not have a large bend.

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 proble...
