A kind of solar water heater multi-sharing individual control device
Technical field the present invention relates to a kind of control system of solar water heating system, particularly a kind ofly can make several separate unit solar water heaters, when being combined into solar water heating system, provides a kind of reliable convenient energy-conservation control mode.
The installation ubiquity of the current solar water heater of background technology does not have normalized phenomenon in a jumble, be placed in the solar water heater main frame of roof, east is put the west and is put and do not have rule, make the limited space of roof can not get reasonable use, the scattered here and there solar water heater main frame of putting of while, seem also very not attractive in appearance, every solar water heater can only provide hot water for a family user, other users can not share this solar water heater, and the solar energy heat collection engineering of installing concentratedly, though every user can both share this system, but all be water-filled all the time in the aqueduct of each household, all to emit a large amount of cold water before each the use, both waste water resource, bring inconvenience in the use to the user again.User's aqueduct will be done heater by service on the other hand, and its aqueduct need add the protection of ribbon heater and insulating sponge, has promptly wasted electric power energy since like this, has influenced the attractive in appearance of building again.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, and is easy and simple to handle, and the separate unit solar water heater is installed concentratedly, gangs up resource-sharing, but the feasible scheme that can independently control mutually.In this scheme, every solar water heater is interconnected into as a whole by section of a pipe, every user can pass through independently aqueduct and gauge tap, enjoy whole hot water of this system, and every user's aqueduct can both be realized the purpose that emptying is freeze proof.
In the solar water heating system of this invention, user's aqueduct is emptying at ordinary times, when certain user need use hot water, open starter gate valve (this valve can be used ordinary ball valve, mechanical delay valve and magnetic valve), the purpose that this starter gate valve is set is in order to inject one section water column in the aqueduct of emptying, after closing starter gate valve, open mixing valve, the previous one section water column that injects was discharged naturally, and because of siphonage with the hot water sucking-off.When the user need stop to use hot water, (deciding on the floor height) starts emptying solenoid valve only to need 1-10 minute in advance, hot water in the aqueduct will drain in the last use of user, as seen in whole use, there is not the hot water waste, and the aqueduct after the emptying is not need to take the electricity insulation to wait measure, so promptly save electric energy, simplified mounting material again, also beautified the installation outward appearance.
Description of drawings Fig. 1 is a system architecture schematic diagram of the present invention
Among the figure: 1-attemperater, 2-intake pipe, 3-emptying solenoid valve, 4-outlet pipe, 5-water-supply-pipe, 6-starter gate valve, 7-mixing valve, 8-running water pipe
The specific embodiment: as shown in Figure 1: intake pipe (2) is made up of a pipe that vertically inserts attemperater (1) inner bottom part, one end of outlet pipe (4) is connected with the upper end of intake pipe (2), the other end of outlet pipe (4) is connected with aqueduct (5), emptying solenoid valve (3) is connected with outlet pipe (4), and water-supply-pipe (5) is connected by starter gate valve (6) with running water pipe (8).The installation requirement of emptying solenoid valve is, valve body will exceed the high-order bit of attemperater all the time, emptying solenoid valve only is used for carrying air to pipeline, stop to contact with water, the air inlet of valve body is communicated with atmosphere, and the gas outlet of valve body is connected with outlet pipe, if place a ventilative foam-rubber cushion in the gas outlet of valve body, can prevent better that then hot water vapor from entering valve body, makes valve not frozen.Can specify by certain family the last water of system's water tank and to finish, longly during the last water drive starter gate valve, can finish the water conservancy project work.Also can adorn the identical user control unit of a cover in addition, be exclusively used in the last water of water tank, wherein if change starter gate valve into automatic valve, then whole system just becomes automatic loading water (this sets of plan does not draw among the figure).A kind of mixing valve with last taps is often arranged on the market now, and during as if this kind of employing mixing valve, last taps has replaced starter gate valve, and then starter gate valve can omit.
It among Fig. 1 a system diagram of forming by two units for four users' uses, the water tank of two separate unit solar water heaters abuts against together in the drawings, and by being connected a communicating pipe, communicating pipe the overcoat heat-preservation cotton, so the cistern water level of two solar water heaters is remained the same from beginning to end, thereby has realized the purpose of four shared these two solar water heaters of user.
As perfection of the present invention, the hot water mouth of mixing valve (7) is connected with water-supply-pipe (5); Cold water outlet is connected with running water pipe (8), and mixing valve cooperates emptying solenoid valve (3) water-supply-pipe (5) to be carried out the effect of emptying except that being used to adjust the coolant-temperature gage in addition.
