Abstract
The utility model belongs to a water tank for a solar water heater, which comprises a water inlet pipe, a water outlet pipe, and a heat-insulating water tank. The utility model is characterized in that the water inlet pipe is connected with a water inlet on the upper part of the heat-insulating water tank, and a water outlet is positioned on the upper part of the heat-insulating water tank; the water inlet on the heat-insulating water tank is connected with a three-way valve, one way of the three-way valve is connected with a water pipe, and one way of the three-way valve is connected with a pipeline led to the inner lower part of the heat-insulating water tank. When the use of the utility model is finished in winter, water in the water inlet pipe and the water outlet pipe is emptied, and the pipeline can not be frozen; the problem that a solar water heater can not be in normal use is solved thereby.
Description
The utility model belongs to solar water heater.
When the solar water heater water tank of prior art uses in the winter time, because environment temperature is lower, the water yield is less in the pipeline, though water tank and pipeline are all taked the insulation measure, problem still can not well solve but pipeline freezes, and has influenced solar water heater normal use in the winter time.
The purpose of this utility model provides a kind of can normally the use in the winter time, has solar water heater's water tank of resistance to frost.
The utility model comprises water inlet pipe, outlet pipe, attemperater, it is characterized in that water inlet pipe connects the water inlet on attemperater top, outlet pipe is connected with the delivery port that is positioned at attemperater top, the attemperater water inlet connects triple valve, triple valve one tunnel taps into water pipe, one the tunnel with lead to that the pipeline of bottom is connected in the attemperater, another road connection check valve.
Be connected in series ball-cock assembly on the pipeline of water inlet of the present utility model bottom to the attemperater.
Communicate with atmosphere behind the escape pipe serial connection check valve at the utility model attemperater top.
After the utility model used in the winter time, the water in emptying water inlet pipe and the outlet pipe can guarantee that when reusing pipeline is unimpeded, therefore, can reach antifreeze purpose, thereby solved the problem that winter solar can normally be used.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 also is the structural representation of the utility model embodiment.
Among Fig. 1, open the valve 12 of serial connection on the water inlet pipe 11, running water is through the bottom of ball-cock assembly 7, triple valve 9 and pipeline 10 inflow attemperaters 4, and hot water flows out from outlet pipe 3, at this moment opens valve 2 and can use hot water.When without hot water, open valve 13, because siphon destroyed by check valve 8, thus the water of emptying valve 12 in the water inlet pipe 11 between the triple valve 9; Open valve 1, can emptying valve 2 water in the outlet pipe 3 between attemperater 4 delivery ports, can guarantee that like this water inlet pipe 11 and outlet pipe 3 do not freeze, thereby guarantee solar water heater's normal use in the winter time.Ball-cock assembly 8 plays water level in the control attemperater 4.
Among Fig. 2, when the water inlet in the attemperater 4 is not connected in series ball-cock assembly to the downward pipeline 10, can in escape pipe 6, be connected in series check valve 5, its effect also is the water that guarantees in emptying water inlet pipe 11 and the outlet pipe 3, guarantee solar water heater's normal use in the winter time, and this attemperater can bear pressure.
Claims (3)
1, a kind of antifreezing type solar water heater water tank, comprise water inlet pipe (11), outlet pipe (3), attemperater (4), it is characterized in that water inlet pipe (11) connects the water inlet on attemperater (4) top, outlet pipe (3) connects the delivery port that is positioned at attemperater (4) top, and attemperater (4) water inlet connects triple valve (9), and triple valve (9) a tunnel connects water inlet pipe (11), one the tunnel is connected with the pipeline (10) that leads to the interior bottom of attemperater (4), and another road connects check valve (8).
