Fig. 1 is a kind of solar water heater water-wastewater system of the present utility model, the structural representation of embodiment 1.
Fig. 2 is a kind of solar water heater water-wastewater system of the present utility model, the structural representation of embodiment 2.
The contrast of code name and title is as follows among the figure:
The last water stop valve of 1-, 2-upper hose, 3-relief valve, 4-water pipe, 5-stop valve, 6-downcomer, the 7-mouth of pipe of ventilating, 8-ball float cage, 9-ball float, 10-blow vent, 11-deflector, 12-filling pipe end, the mouth of a river under the 13-, 14-check valve, 15-adiabator layer, 16-breather pipe, 17-storage tank, 18-mixing valve.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described in detail.
Implementation column 1, as shown in Figure 1: the storage tank of solar water heater (17), the bottom connects upper hose (2), storage tank (17) top connects downcomer (6), and the following mouth of a river (13) is to make that the afloat ball float of the water surface has certain come-up apart from directly not blocking blow vent to blow vent storage tank in the position of storage tank (17) upper shed.Downcomer is not installed any stop valve on (6), is the siphunculus of downward water outlet current.Storage tank (17) top connects breather pipe (16).In storage tank (17), ball float cage (8) is installed on the blow vent (10), in cage, be equipped with and can fluctuate less than ball float cage diameter, greater than the ball float (9) of blow vent diameter, ball float can be that the surface has certain flexible ball float.On the upper hose (2) of indoor section, install water stop valve (1).Go up at the upper hose (2) of the storage tank direction of last water stop valve (1) and water pipe (4) to be installed to connect downcomer (6), go up at water pipe (4) stop valve (5) is installed.Be connected with water pipe (4) at downcomer (6) on the downcomer (6) of prescription top storage tank direction, be close to downcomer (6) and with the junction of water pipe (4) check valve (14) be installed, check valve is opening at ordinary times, and check valve ends when running into reverse flow.At downcomer (6) relief valve (18) go up to be installed, when adopting top water law water intaking, the water outlet accident is obstructed under the situation, and when the storage tank internal pressure rose to the pressure that can bear near storage tank, relief valve was opened pressure release, prevented the bad storage tank that rises.Breather pipe (16) is installed in the adiabator layer (15), and the ventilation mouth of pipe (7) of breather pipe is below adiabator layer.Because can stoping the interior hot-air of storage tank to flow, the principle that hot-air upwards flows, the ventilation mouth of pipe reduce thermal loss downwards outside storage tank.Filling pipe end (12) top certain distance mounting guiding board (11) in storage tank (17).When adopting top water law water intaking, the cold water that upper hose (2) upwards ejects flows to the storage tank bottom through the deflector water conservancy diversion, and cold water can once not be flushed among the hot water layer of upper strata and cause water outlet sometimes hot and sometimes cold like this.
The course of work of present embodiment is: when adopting top water water-fetching method, open water stop valve (1) top water in storage tank, the interior water level of storage tank (17) rises and surpasses delivery port (13), the ball float of Shang Shenging is blocked blow vent (10) and is given the delivery port certain pressure simultaneously, hot water passes through check valve (14) through delivery port, with the cold water mix that stop valve (5) is emitted to downcomer (6) by water pipe (4), regulate water temperature, emit hot water.Close when stopping using and close water level decline in water stop valve (1) storage tank, ball float decline blow vent is opened, and when water level was lower than delivery port, storage tank is water outlet no longer, and the water in the downcomer (6) drains only naturally, closes stop valve (5).
During the method for adopt falling into water water intaking, open stop valve (5) and use water stop valve (1) and emit an amount of cold water and regulate water temperature, hot water enters downcomer (6) by water pipe (4), and check valve (14) prevention is returned water to the top of downcomer (6).When stopping using, close and close water stop valve (1) and stop valve (5).During moisturizing, open stop valve (1) and go up water by upper hose (2) in storage tank in storage tank when need, water is full in storage tank, and water level surpasses delivery port (13) water and will overflow by downcomer (6), and the prompting storage tank is filling up water.
The course of work of present embodiment is when adopting top water law water intaking, and to the top water end (W.E.), at this moment upper hose (2) is opened with the handle plate of mixing valve (18), and water pipe (4) ends, water through upper hose (2) to storage tank top water.When adopting the method for falling into water water intaking, the handle wrench of mixing valve (18) is held to falling into water, at this moment, end the mixing valve lower end of upper hose (2), and open the upper end, and water pipe (4) is opened, hot water in the storage tank is through the mixing valve epimere pipe of upper hose (2), water pipe (4), and downcomer (6) is emitted hot water.
