Problems solved by technology

But it still has the following disadvantages: 1. The water in the pipe body between the tee and the water tank cannot be completely discharged, and it is still possible to freeze in the pipe in the severe winter
2. The lifting of the tee will drive the connected pipelines to move together, and the lifting and lowering parts of the upper and lower water pipes are prone to "U" bends, which will cause water to freeze and block when emptying
3. The sewer pipe connected to the tee will move down under the action of gravity and temperature difference after long-term use, so the lifting device will not be able to lift the tee to the preset position due to limited power
4. The air supply pipe of the elastic plastic coil is not easy to protect the insulation layer. In colder weather, it is easy to freeze and block the air supply pipe in a short time, so that the sewer pipe cannot be emptied.

Abstract

A solar evacuating and anti-freezing device comprises a lifting mechanism and an evacuating hose assembly. The evacuating hose assembly comprises a special-shaped tee joint, a lifting hose, a two-way joint and an air compensating pipe, wherein the lifting hose consists of a thick lifting hose and a thin lifting hose, the special-shaped tee joint is of a water jacket structure, a water pipe joint of a water tank is connected with a water pipe of the water tank, a thick hose joint is connected with the thick lifting hose, a thin hose joint is connected with the thin lifting hose, the thin lifting hose is sleeved in the thick lifting hose and shorter than the thick lifting hose, upper and lower water pipe joints are connected with upper and lower water pipes, the other end of the thick lifting hose is connected with the air compensation pipe through the two-way joint, and the air compensation pipe is vertical and tilted leftwards relative to the two-way joint. The lifting hose of a sleeve structure, the temperature of remained water of an inner pipe is favorably kept after the outer pipe is evacuated, and the inner pipe is guaranteed not to freeze.

Description

technical field [0001] The invention relates to a matching equipment of a solar water heater, in particular to a solar drain pipe antifreeze device. Background technique [0002] In the prior art, after the indoor valve of the general solar water heater is closed, there is some water in the pipeline between the solar water heater and the indoor valve, and the water will gradually cool down if it stays in the pipeline for a long time, and the cold water must be drained when the water is used next time. cause waste. In addition, when the weather temperature is low in winter, the water stored in the pipes will freeze, causing freezing blockage or bursting of water pipes, resulting in users being unable to use hot water normally. Therefore, in order to solve this problem, many manufacturers have developed solar water heaters with electric heating function or antifreezing devices of electric emptying valve type, but these devices are not very good in terms of convenience of use,...
