Description
Technical field
The utility model relates to a kind of water supply and drainage mechanism in the water heater production field, particularly a kind of water supply and drainage mechanism of solar water heater.
Background technology
Because the upper and lower water pipe of existing solar water heater all is contained in bottom or the sidepiece of water tank, causes following two defectives: at first, open valve and can not emit immediately hot water; Secondly, in the winter of cold, the frozen pipe phenomenon is often arranged, in case frozen pipe so that whole winter water heater just ineffective, even pipeline breaking causes serious consequence.
The utility model content
For the defective that existing solar water heater upper and lower conduit arranges, the utility model provides a kind of water supply and drainage mechanism of solar water heater.
To achieve these goals, the utility model institute Adopts measure is:
A kind of water supply and drainage mechanism of solar water heater, comprise water tank and the upper hose and the downcomer that are connected on the water tank, the water inlet of upper hose links to each other with running water, the water inlet is provided with the first control valve, the end of downcomer is provided with the mouth of a river first time, upper hose and downcomer are installed the top that is connected to water tank, upper hose is entered the bottom of straight-through water tank by tank top, the tight-lipped top of suffering water tank of sewer pipe, be connected with the first auxiliary tube on the upper hose, be provided with the 3rd control valve on the first auxiliary tube, be connected with the second auxiliary tube on the downcomer, the mouth of pipe of the first auxiliary tube and the second auxiliary tube directly communicates with air, and the water inlet of upper hose is provided with the second delivery port, and the second water outlet is provided with the second control valve;
The junction of described the first auxiliary tube and upper hose is lower than the top of water tank;
Described the second auxiliary tube is concordant with the top of water tank with the junction of downcomer;
The top 40cm-60cm of the high water tank of the mouth of pipe that communicates with air in described the first auxiliary tube and the second auxiliary tube.
The beneficial effects of the utility model: overcome the defective of existing solar water heater, accomplished to open valve and can emit hot water; Can put water in the pure water pipe fully in the winter of cold, accomplish antifreeze effect, the frozen pipe phenomenon can not occur.
Description of drawings
Fig. 1, structural principle block diagram of the present utility model.
The specific embodiment
A kind of water supply and drainage mechanism of solar water heater, comprise water tank 1 and the upper hose 2 and the downcomer 3 that are connected on the water tank 1, the water inlet 4 of upper hose 2 links to each other with running water, water inlet 4 places are provided with the first control valve K1, the end of downcomer 3 is provided with the mouth of a river 5 first time, upper hose 2 and downcomer 3 are installed the top that is connected to water tank 1, upper hose 2 is entered the bottom of straight-through water tank 1 by water tank 1 top, the top of the adjacent water tank 1 of downcomer 3 mouths of pipe, be connected with the first auxiliary tube 7 on the upper hose 2, be provided with the 3rd control valve K3 on the first auxiliary tube 7, be connected with the second auxiliary tube 8 on the downcomer 3, the mouth of pipe of the first auxiliary tube 7 and the second auxiliary tube 8 directly communicates with air, and water inlet 4 places of upper hose 2 are provided with the second delivery port 6, the second delivery ports 6 places and are provided with the second control valve K2; The junction of described the first auxiliary tube 7 and upper hose 2 is lower than the top of water tank 1; Described the second auxiliary tube 8 is concordant with the top of water tank 1 with the junction of downcomer 3; The top 40cm-60cm of the high water tank 1 of the mouth of pipe that communicates with air in described the first auxiliary tube 7 and the second auxiliary tube 8.
Operation principle of the present utility model: upper hose 2 links to each other with running water, downcomer 3 is often opened, and all the time for hollow, under the state of the full hot water of water tank 1 storage, open the first control valve K1, close the second control valve K2, running water by upper hose 2 water fillings in the bottom of water tank 1, hot water is just flowed out by downcomer 3, reaches and opens the first control valve K1 instant-heating and outlet hot purpose.At the first auxiliary tube 7 the 3rd control valve K3 is housed, closes the 3rd control valve K3 summer, open the second control valve K2 and just can emit whole hot water in the water tank by the second delivery port 6 places; Open valve K3 winter, close the first control valve K1, and open the second control valve K2, can emit cold water in the upper hose 2, at this moment, first, second water pipe plays antifreeze effect all for hollow state.The first auxiliary tube 7 and the second auxiliary tube 8 communicate with air, about half meter of the high water tank of the mouth of pipe, and the first auxiliary tube 7 is contained in the place of low flush tank under at least, can accomplish to put fully winter the water in the pure water pipe.
The beneficial effects of the utility model: overcome the defective of existing solar water heater, accomplished to open valve and can emit hot water; Can put water in the pure water pipe fully in the winter of cold, accomplish antifreeze effect, the frozen pipe phenomenon can not occur.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
