Description

A kind of solar pipe defroster and method
Technical field
The invention belongs to technical field of solar, relate in particular to a kind of solar pipe defroster and method.
Background technology
Traditional solar water heater inlet and outlet pipe lines, although at its lateral wall, be provided with protective material, due to severe winter excessive temperature low, freeze even to cause water pipe explosion toward contact meeting, hot water can not normally be used.
In prior art, part user, in order also normally to use solar water heater in severe winter, can only transform again to solar water heater, and solar pipe defroster is installed.
Common solar pipe defroster has following three kinds: the antifreeze EGR of two-tube siphon, heating tape device and exhaust-valve device.All there is many deficiencies in above-mentioned three kinds of devices: one, the antifreeze EGR of two-tube hydrocone type is installed on solar energy water heater pipe, although can solve the antifreeze problem of solar pipe in winter, but in siphonic process, can consume the partial heat energy of solar water heater absorption on daytime, solar storage water tank water temperature is declined.If encounter continuous situation of cloudy day, this pipeline still may freeze.And for old-fashioned solar water heater transformation, not only need pipe laying again, damage renovated house, and effect is bad.Two, on solar energy water heater pipe, be arranged on heating wire (heating tape) device, in winter, by heating, prevent from freezing, but in real process, consumed a large amount of electric energy.And for old-fashioned single tube solar energy, need to tear pipe wiring open, even damage renovated house.Three, exhaust-valve device is installed on solar energy water heater pipe, by add pipe line evacuation valve in pipeline, the water of pipeline is pumped.This scheme can solve ice formation issues, and also can solve water outlet is heat problem, but need to carry out rewiring, installs very inconveniently, and installation cost is higher.
Moreover above-mentioned three kinds of methods are to have utilized manually carries out the method for pipeline exhausting device, if user forgets emptying pipe, this solar energy water heater pipe still can freeze.
Summary of the invention
The object of this invention is to provide a kind of solar pipe defroster and method, can avoid damaging renovated house, installation is simple, convenient and cost is lower, and without manually emptying, antifreezing effect is good.
In order to realize foregoing invention object, technical solution of the present invention is as follows:
A solar pipe defroster, for comprising the aqueduct of the solar water heater of aqueduct and storage tank, is provided with water flow meter, triple valve, hydraulic gage and two-port valve on described aqueduct, described solar pipe defroster comprises:
Be used for gathering water flow meter signal, consult emptying needs with secondary signal control cabinet, and control the first signal control cabinet of triple valve closure or openness;
Be used for gathering hydraulic gage signal, consult emptying needs with first signal control cabinet, and control the secondary signal control cabinet of two-port valve closure or openness;
Further, described triple valve one end is connected with storage tank, and one end is connected with air, and the other end is connected with aqueduct.Any two ends of triple valve can be used in conjunction with, and is reached for storage tank water inlet or makes the effect that in aqueduct, current reflux.
Further, described solar pipe defroster also comprises that described two-port valve one end is connected with return tank for collecting the return tank of aqueduct recirculation water, and the other end is connected with aqueduct.Can collect the water that aqueduct refluxes, carry out secondary utilization.
Further, in described return tank vertical direction lower than aqueduct setting.When air end and aqueduct perforation, the water in aqueduct can be because gravity automatic back flow be in return tank.
Further, on described aqueduct, be also provided with helix tube.In emptying rear aqueduct, it is air, because storage tank has pressure to the air of aqueduct, the volume of air of aqueduct can reduce by pressurized, on aqueduct top, there will be a small amount of ponding, described helix tube is used for storing a small amount of ponding, because helix tube You Gu district, even if freeze, also can not affect the circulation of whole aqueduct.
The invention allows for the solar pipe means to prevent freezing that adopts above-mentioned solar pipe defroster: a kind of solar pipe means to prevent freezing, for comprising the aqueduct of the solar water heater of aqueduct and storage tank, on described aqueduct, be provided with water flow meter, triple valve, hydraulic gage and two-port valve, the method comprises the following steps: gather water flow meter signal, consult emptying needs with secondary signal control cabinet, and control triple valve closure or openness; Gather hydraulic gage signal, consult emptying needs with first signal control cabinet, and control two-port valve closure or openness.
The solar pipe defroster that the present invention proposes and the solar pipe means to prevent freezing that has used this solar pipe defroster, gather water flow meter with the first control cabinet and have or not water-flow signal, and the second control cabinet gathers hydraulic gage and has or not hydraulic signal; Only have non-water flow in aqueduct detected simultaneously, while having two signals of hydraulic pressure, the first control cabinet is just controlled triple valve makes aqueduct communicate with air, and the second control cabinet is controlled two-port valve and opened, and aqueduct is communicated with return tank, realize aqueduct gas is utilized to replace water, water is drained in return tank; After tube emptying completes, extend a period of time, two control cabinet automatic control tee valves make aqueduct communicate, close two-port valve with storage tank, guarantee that user normally uses solar water heater; In sensing chamber's Outer Tube non-water flow, without hydraulic pressure (yard piping is emptying) or to have current, have hydraulic pressure (hot water of user in using solar water heater storage water tank or water on to solar water heater storage water tank) situation can not carry out gas is utilized to replace water to yard piping emptying.Realizing the emptying technology of fully-automatic intelligent, avoid manually emptyingly occurring that pipeline freezes because user forgets, is thermal effect thereby reach antifreeze, water outlet; Signal wireless transmission, without tearing pipe, wiring open, installs simply, does not damage body of wall attractive in appearance, is applicable to the transformation of new and old solar energy.
