Abstract
The utility model relates to solar equipment, in particular to an improved solar water heater water tank. The mouth of an exhaust pipe of the water heater water tank is higher than the mouth of a hot water outlet pipe; the lower edge of the mouth of the exhaust pipe in the water tank is provided with a water level sensor; the outer end of the exhaust pipe is respectively connected with a blowdown pipe and a bleeder pipe through a three-way pipe; the blowdown pipe and the bleeder pipe are respectively provided with a one-way valve; a cold water pipe is provided with an electromagnetic valve connected with the output end of an electronic switch; and the water level sensor is connected with the input end of the electronic switch through a signal line. The water tank provided by the utility model has a simple structure and less investment and is convenient to operate; water resources are not wasted; and a heat preservation effect can be enhanced and the water tank is prevented from being flattened when being frozen in winter.
Description
Technical field
The utility model relates to a kind of solar facilities, particularly improved solar water heater water tank.
Background technology
Traditional solar water heater water tank structure is, the cold water pipe inlet is arranged at the bottom of the water tank, and the hot-water line outlet is located at water tank upper, blast pipe also is located at top, and has been equipped with water supply tank and comes how many amount of makeup water of going out according to hot water.It is found that in long-term use if the water in the better water-heater water tank of sunlight often is in fluidized state, a large amount of vapours can be discharged from exhaust pipe mouth, evening, the water temperature in the water tank descended much during with hot water, had caused heat-energy losses.In addition, temperature is in 0 ℃ area in the winter time, and the ponding section of blast pipe can be frozen, and gets lodged in exhaust pipe mouth when people use the ice that hot water fashion is not melted, and causes water-heater water tank to be in negative pressure state, causes water tank to be flattened by atmosphere.In order to solve the problem that water tank is crushed, the method that people adopt is to be equipped with special-purpose low temperature jettison gear on water tank, perhaps manually discharges water, and all there is waste water resource in these methods, and it is more to increase cost of investment, and operation is the problem of trouble.
Summary of the invention
The purpose of this utility model provides a kind of high-efficiency insulated anti-freezing solar water heater water tank, and it is simple in structure, and small investment is easy to operate, and waste water resource is not crushed in the time of can improving heat insulation effect and prevent the water tank ice up in winter.
The purpose of this utility model is achieved in that exhaust pipe mouth is higher than hot water effluent's mouth of pipe, water tank inside exhaust pipe mouth lower edge is equipped with level sensor, the outer end of blast pipe is connected to blowdown pipe and bleeder pipe respectively by three-way pipe, check valve is housed respectively on blowdown pipe and bleeder pipe, the magnetic valve that is connected with the electronic switch output is housed on the cold water pipe, and level sensor connects the input of electronic switch by holding wire.When the water in the water tank was heated, the check valve on the bleeder pipe was in closed condition, had avoided the heat-energy losses of a large amount of hot water vaporizations, simultaneously when have in the water tank certain pressure when existing heat insulation effect can improve, and water temperature also can be more even; And the exhaust pipe mouth lower edge is equipped with level sensor, can prevent that the water in the water tank from entering blast pipe, and has solved blast pipe at lower cost by the technical problem of freezing shutoff.
Of the present utility modelly also comprise following concrete technical scheme.
The check valve of being adorned on the bleeder pipe is a spring closing type check valve, rely on the elastic force of spring to come valve-off, and the closing presure of valve is less than the safe design pressure of water tank.The closing presure of this spring closing type check valve is arranged to the little 30～60kPa of safe design pressure than water tank, can guarantee that like this result of use is good, uses simultaneously and safety.
The magnetic valve that cold water pipe is adorned is arranged on the indoor cold water pipe of user, can reach convenient for maintaining, purpose safe in utilization.
The beneficial effects of the utility model are: the outlet of blast pipe is provided with the mode of check valve, can make to keep certain pressure in the water tank, helps energy-saving heat preserving, and safety effect is played in exhaust when spring closing type check valve can guarantee pressure arrival predetermined value again simultaneously; Being provided with of level sensor guaranteed that exhaust pipe mouth can be by freezing shutoff, and cost is lower, also do not need to discharge water to solve the problem that winter, water tank damaged; It is indoor by electronic switch control that magnetic valve is arranged on the user, reached the purpose that strong and weak electricity separates, the better and safety of environment for use, and be convenient to daily maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: cold water pipe 1, hot-water line 2, water tank 3, level sensor 4, spring closing type check valve 5, check valve 6, blast pipe 7, holding wire 8, user are indoor 9, electronic switch 10, magnetic valve 11, bleeder pipe 12, blowdown pipe 13.
The specific embodiment
Referring to Fig. 1, the mouth of pipe of blast pipe 7 is higher than the delivery port of hot-water line 2, at water tank 3 inside exhaust pipe mouth lower edges level sensor 4 is housed, and the top of blast pipe is connected to blowdown pipe 13 and bleeder pipe 12 respectively by three-way pipe.One common check valve is installed on blowdown pipe, can be prevented that at ordinary times water vapour from leaking, and cold water pipe 1 when cutting off the water water can in time open tonifying Qi, prevent that water tank 3 from flattening; Spring closing type check valve 5 is housed on the bleeder pipe 12, usually rely on the elastic force valve-off, keep the steam pressure in the water tank 3, and when steam pressure in the water tank 3 surpasses safe design pressure, because the closing presure of spring sets value less than this, so valve is opened automatically, guarantee the safe in utilization of water tank, the closing presure of this spring closing type check valve 5 is arranged to the little 30～60kPa of safe design pressure than water tank in actual use.The magnetic valve 11 that is connected with the output of electronic switch 10 is housed on the cold water pipe 1, this magnetic valve 11 is arranged on user indoor 9 the cold water pipe 1, level sensor 4 in the water tank 3 is connected in the input of electronic switch 10 by holding wire 8, when water tank 3 middle water levels arrive the position of level sensor 4, magnetic valve 11 can obtain the shutdown signal through amplifying, thereby never can water in the assurance blast pipe, also just prevented the phenomenon of ice up in winter shutoff.
