Description

Point storehouse coiled pressure-bearing solar water heater that can Double-evacuation
Technical field
The utility model relates to a kind of solar water heater, especially can emptying upper hose and the coiled pressure-bearing solar water heater of downcomer.
Background technology
Although existing coiled pressure-bearing solar water heater has solved thermal-collecting tube fouling, the problem that supplying hot water hydraulic pressure is low, owing to also existing rate of thermal water utilization low, the problem that while stopping water, upper hose and downcomer cannot be emptying.Existing coiled pressure-bearing solar water heater attemperater is all a storehouse, when its water temperature inside is during slightly lower than bathing temperature, although the water in water tank can also continue, to through coil pipe tap water heating, cannot utilize because leaving water temperature does not reach bathing temperature.Emptying is that the difficult problem overcoming is all badly in need of in all solar water heaters producer, and especially in northern China, emptying technology has determined that can this solar water heater use in the winter time.Existing emptying technology is the way that relies on magnetic valve, motor-driven valve or adopt top water, siphon substantially, but these technology have been brought again how new problem in having solved emptying problem, as do not have electricity cannot be emptying, add cold water whole box water very rapid cooling, story height cannot suck water etc. completely.Therefore hindered the universal of coiled pressure-bearing solar water heater.
Summary of the invention
In order to overcome, existing coiled pressure-bearing solar water heater rate of thermal water utilization is low, stopping after water cannot emptying upper hose and the problem of downcomer, the utility model provides a kind of point storehouse coiled pressure-bearing solar water heater that can Double-evacuation, this solar water heater can not only improve the rate of thermal water utilization of coiled solar water heater, can also stop automatic-discharging upper hose and downcomer after water.
The utility model solves the technical scheme that its technical problem adopts: from inner, warming solar energy water tank is divided into three independently heating cabinets, its volume is followed successively by one-level heating cabinet, secondary heating cabinet and three grades of heating cabinets from big to small, and the heating cabinet of every two-stage neighboring all uses U-shaped pipe to be communicated with from bottom.Coil pipe passes through one-level heating cabinet, secondary heating cabinet and three grades of heating cabinets successively, and the closeness of this process coil pipe is successively decreased step by step, and coil pipe two ends connect respectively inlet triplet for water and outlet three way.Inlet triplet for water position is fixed on one-level heating cabinet inner top, and its lower end is connected with cold water inlet, and its upper end is communicated with air inlet A, and outlet three way position is fixed on three grades of heating cabinet inner tops, and its lower end is connected with hot water outlet, and its upper end is communicated with air inlet B.Check valve A and check valve B are installed at air inlet A and air inlet B place respectively, check valve A toward air inlet A direction for closing, check valve B toward air inlet B direction for closing, thereby prevented that running water from overflowing from air inlet A or air inlet B, avoided waste and pressure release.Establish an automatic water supply tank in one-level heating cabinet side, establish exhaust outlet on top, three grades of heating cabinet sides, automatic water supply tank full water water level is set lower than exhaust outlet.
Automatic water supply tank carries out uninterrupted automatic water supplement to one-level heating cabinet, and one-level heating cabinet is communicated with from bottom with U-shaped pipe with three grades of heating cabinets with secondary heating cabinet, secondary heating cabinet, has reached the effect of common moisturizing.
In the time of needs water, open copper ball valve and mixed water valve, running water enters one-level heating cabinet from upper hose, enter coil pipe by inlet triplet for water, through one-level heating cabinet, secondary heating cabinet, three grades of heating cabinet heating, check valve A and check valve B close automatically simultaneously, thereby form the pipeline of sealing successively, water in coil pipe reaches bathing temperature and enters downcomer by outlet three way again, finally by mixed water valve from gondola water faucet out.。Along with constantly passing through of running water, the water temperature of three heating cabinets all can decline, and one-level heating cabinet water temperature declines maximum, and three grades of heating cabinet water temperatures decline minimum.Reason is: the first, and the coil pipe closeness in one-level heating cabinet, secondary heating cabinet, three grades of heating cabinets is successively decreased step by step; Second, running water is introduced into the coil pipe in one-level heating cabinet, after the heating of one-level heating cabinet, enter again the coil pipe of secondary heating cabinet, after the heating of secondary heating cabinet, enter again the coil pipe of three grades of heating cabinets, hence one can see that, and to enter the water of secondary heating cabinet coil pipe higher than the temperature that enters one-level heating cabinet coil pipe, and the water that enters rear three grades of heating cabinet coil pipes is higher than the temperature that enters secondary heating cabinet coil pipe again.Therefore in the time of water, three heating cabinet water temperatures declines are followed successively by little greatly: one-level heating cabinet, secondary heating cabinet, three grades of heating cabinets.When water temperature in one-level heating cabinet drops to lower than can bathing temperature time, the water temperature in secondary heating cabinet and three grades of heating cabinets, still higher than bathing temperature, now can continue to use; When water temperature in one-level heating cabinet, secondary heating cabinet all drops to lower than can bathing temperature time, as long as the water temperature in three grades of heating cabinets higher than bathing temperature, still can continue to use; Until the water temperature in three grades of heating cabinets during also lower than bathing temperature, just cannot be used.Now the water temperature in one-level heating cabinet, secondary heating cabinet is far below bathing temperature, and particularly the water temperature in one-level heating cabinet has approached running water temperature.The volume that adds upper level heating cabinet and secondary heating cabinet is larger, has therefore greatly improved the rate of thermal water utilization of coil pipe solar water heater.
In the time stopping water, first close copper ball valve, continue to keep mixed water valve in mixed water washing bath state.Now check valve A and check valve B open automatically, water in downcomer and upper hose is because be subject to the effect of gravity, to dirty finally by mixed water valve place according to each 50 percent ratio mixing after from gondola water faucet out, gondola water faucet now out be not cold water, still can use, thereby not cause waste.Again emptying the water in upper hose and downcomer, avoided cannot normally using because the water freezing in pipeline stops up the solar water heater causing simultaneously.
The beneficial effects of the utility model are to solve the easy fouling of thermal-collecting tube of solar water heater, when hydraulic pressure is little.Improved greatly the rate of thermal water utilization of coiled solar energy, realized automatic-discharging upper hose and downcomer, and without installing electronic equipment, failure rate is low, safeguards letter, easy to use.
