Abstract
The utility model provides a pressure -bearing formula solar water heater system of pipeline evacuation. Be equipped with a check valve at the top of water tank, position that the sail pipeline is close to the water tank is equipped with a check valve, and there is a check valve on the upper portion of sail pipeline through tee junction, is equipped with valve that a control intake and a control drainage's valve in sail pipeline lower part, is equipped with one in offal pipeline lower part and controls out the valve of water and a control drainage's valve. The method of this kind of evacuation realizes by water pressure and self gravity, useless electric device on the water tank, and safe and reliable, the water tank overwhelming majority times are in not artesian condition, can prolong the life of water tank greatly. The pipeline outside need not extra heat preservation or other freeze protection measures, practices thrift the cost. The use three -way valve is adjusted, and easily control is more convenient.
Description
Technical field
The present invention relates to a kind of solar water heater system, particularly relate to a kind of pressure-bearing type solar water heater system with air emptying function.
Background technology
Pressure-bearing type solar water heater water outlet is powerful, bath comfort, more and more welcomed by the people, but in northern area uses, there will be the problem of frozen block in winter, what current pressure-bearing type solar water heater thermal-arrest heat-exchange system was more employs antifreeze medium indirect heat exchange mode, water tank and heat collector anti-freezing property relatively good, but upper and lower conduit road is its weakest link.Solve in prior art winter frozen block except thicken pipe insulating layer, also have the method such as heating tape, emptying pipe.Heating tape method needs to consume a certain amount of electric energy, there is potential safety hazard, has cold water in addition in pipeline, and first will bleed off cold water during use, water wasting is time-consuming; Mostly exhaust method is to be used on unpressurized water heater, generally installs emptying magnetic valve or motor-driven valve in the bottom near water tank, and indoor to outdoor laying holding wire, cannot use if had a power failure.These problems constrain popularization and the use of pressure-bearing type solar water heater.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provides a kind of easy to operate, the pressure-bearing type solar water heater system of the pipeline evacuation of dependable performance.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of pressure-bearing type solar water heater system of pipeline evacuation, comprise water tank, heat collector, watering pipeline and drainage pipeline, it is characterized in that: be provided with a check valve at the top of water tank, watering pipeline is provided with a check valve near the position of water tank, the top of watering pipeline is connected with a check valve by threeway, be equipped with one in watering pipeline bottom and control the valve of water inlet and the valve of a control draining, be equipped with one in drainage pipeline bottom and control the valve of water outlet and the valve of a control draining.
When using water, opening water supply valve door and flowing water Valve, closing two water discharging valves simultaneously, water is full of all pipelines gradually, and the check valve on water tank and the check valve on watering pipeline, by the effect of hydraulic pressure, are in closed condition, now, water tank pressure-bearing, realizes pressure-bearing water outlet.During without water, close water supply valve door and flowing water Valve, open two water discharging valves, by the impact of gravity, the water in pipeline can be discharged gradually simultaneously, by the impact of negative pressure, one-way valve opens air inlet, the pressure in balanced reservoir and pipeline, the check valve of water tank bottom can ensure that water can not flow out, until water tank level is suitable for reading equal with outlet pipe, now water tank is in not artesian condition.
As a modification of the present invention, upper and lower conduit road arranges two two position three-way valves respectively to replace water supply valve door, flowing water Valve and two water discharging valves, synchronously be transferred to two two position three-way valves during water and 1. and 2. lead to, hydraulic water is held in realization, time emptying, two two position three-way valves are synchronously transferred to and 2. and are 3. led to, and realize the emptying of pipeline.
This emptying method realizes by hydraulic pressure and self gravitation, and on water tank, useless electric device, safe and reliable, and the water tank overwhelming majority time is in not artesian condition, greatly can extend the service life of water tank.Pipeline is outside without the need to extra insulation or other antifreezing measures, cost-saving.Use triple valve regulates, and is easy to control, more convenient.

Fig. 1 is the schematic diagram of the first embodiment of the utility model.
Fig. 2 is the schematic diagram of the utility model the second embodiment.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further elaborated.
As shown in Figure 1, the pressure-bearing type solar water heater system of a kind of pipeline evacuation of the present invention, comprise water tank 1, heat collector, watering pipeline and drainage pipeline, a check valve 2 is provided with at the top of water tank 1, watering pipeline is provided with a check valve 4 near the position of water tank, the top of watering pipeline is connected with a check valve 3 by threeway, be equipped with one in watering pipeline bottom and control the valve 8 of water inlet and the valve 7 of a control draining, be equipped with one in drainage pipeline bottom and control the valve 5 of water outlet and the valve 6 of a control draining.When using water, opening water supply valve door 8 and flowing water Valve 5, closing water discharging valve 7 and 6 simultaneously, water is full of all pipelines gradually, and the check valve 2 on water tank and the check valve on watering pipeline 3, by the effect of hydraulic pressure, are in closed condition, now, water tank pressure-bearing, realizes pressure-bearing water outlet.During without water, close water supply valve door 8 and flowing water Valve 5, open water discharging valve 7 and 6, by the impact of gravity, the water in pipeline can be discharged gradually simultaneously, by the impact of negative pressure, air inlet opened by check valve 2 and 3, the pressure in balanced reservoir and pipeline, and the check valve 4 of water tank bottom can ensure that water can not flow out, until water tank level is suitable for reading equal with outlet pipe, now water tank is in not artesian condition.
As shown in Figure 2, upper and lower conduit road arranges two two position three-way valves 10 and 9 respectively to replace water supply valve door 8, flowing water Valve 5 and two water discharging valves 7 and 6, synchronously be transferred to two two position three-way valves during water and 1. and 2. lead to, hydraulic water is held in realization, time emptying, two two position three-way valves are synchronously transferred to and 2. and are 3. led to, and realize the emptying of pipeline.
