Abstract
The utility model discloses a device for evacuation and freeze prevention of a solar water heater pipeline, belongs to solar water heaters, and particularly relates to a solar water heater with a freeze-prevention device. The device for the evacuation and the freeze prevention of the solar water heater pipeline comprises a water diversion inserting pipe inserted into the bottom portion of a heat preservation water storage barrel, the upper end of the water diversion inserting pipe is connected to a main pipe of a T-shaped three-way pipe fitting, the other end of the main pipe is connected with a ventilating pipeline with the tail end being provided with a ventilating valve, a water supply and drainage sharing pipeline is connected on a branch pipe of the three-way pipe fitting, the lower end of the pipeline is respectively connected with a tap water pipeline and a shower nozzle through a water distribution three-way valve, and an air pump is arranged on the water supply and drainage sharing pipeline above the water distribution three-way valve through the three-way pipe fitting. The evacuation of the water supply and drainage sharing pipeline can be achieved to prevent a freeze injury simply by changing the length of the water diversion inserting pipe, adding the three-way pipe fitting and the ventilating pipeline equipped with the valve and mounting the hand-operated air pump on the water supply and drainage sharing pipeline, and hot water can be directly used. The device has the advantages that the structure is simple, energy is saved, and safety and reliability are achieved.
Description
Technical field
The utility model belongs to solar water heater, particularly use ventilative pipeline and hand aspiration pump as defroster solar water heater.
Background technology
Conventionally solar water heater can not be used winter, there is frozen pipe phenomenon in low temperature, make Pipeline damage, in the market the large class of device main two of existing solution low temperature frozen pipe: a class adopts can heated type Anti-freezing pipeline, and after during use, its electrical heating being thawed, draining is used.Because of the whole pipeline of heating wire layout, phenomenon, the very rapid wear such as often occur electric leakage or short circuit, open circuit.Two classes adopt magnetic valve, with it, realize tube emptying, and fault is more frequent, need do diversion to pipeline and process while using water heater, very loaded down with trivial details; Cut two kinds and all need power supply, often occur leaky in use procedure, danger coefficient is very high.Also have sub-fraction manually to solve the device of tube emptying, but more loaded down with trivial details because of diversion processing, use is inconvenient, does not all obtain large-scale promotion and uses.
Utility model content
In order to overcome the deficiency of existing solar energy water heater pipe evacuation and anti-freezing technology, the utility model provides a kind of device of solar energy water heater pipe evacuation and anti-freezing, the device of this solar energy water heater pipe evacuation and anti-freezing is not only realized tube emptying by controlling the closure of ventilative pipeline, can be under the state of tube emptying, manually diversion is flowed out hot water.
The utility model solves the technical scheme that its technical problem adopts: a kind of device of solar energy water heater pipe evacuation and anti-freezing, comprise the insulation water butt being arranged on solar thermal collector, insulation water butt is provided with passage, the water supply pipeline being communicated with water supply pipe and the sewer pipe being connected with shower nozzle, control the valve of upper and lower water, it is characterized in that: described insulation water butt is provided with the diversion intubate that is inserted into bottom of the barrel, diversion intubate upper end is connected on the supervisor of T-shaped tee pipe fitting, supervisor's the other end is connecting the ventilative pipeline that end is equipped with ventilative valve, on the arm of tee pipe fitting, connecting upper and lower water common conduit, this lower end of duct is connected with shower nozzle with water supply pipe respectively by water distribution triple valve, the common conduit of water up and down of water distribution triple valve top is used tee pipe fitting that aspiration pump is installed.
In the pump case of described aspiration pump, spring air bag is housed, the base of air bag bottom is provided with the air admission hole that leads to upper and lower water common conduit, and breather cheek valve is housed in hole, and the unidirectional air outlet valve communicating with atmosphere is also housed on base, and depression bar is equipped with on spring air bag top.
Described aspiration pump is elastic sphere, and the breather cheek valve that connects upper and lower water common conduit is equipped with in spheroid one end, and the other end is provided with unidirectional air outlet valve.
Using method of the present utility model is when needing emptying upper and lower conduit road, to close under the state of water distribution triple valve to open the tee pipe fitting that ventilative valve air enters ventilative pipeline and arrives diversion intubate top, water level in diversion intubate drops to the water level in insulation water butt, open water distribution triple valve, water in upper and lower conduit road is emptying through shower nozzle, can avoid freezing in upper and lower conduit road freezing, when the bathing of needs water, close ventilative valve, hand aspiration pump makes in upper and lower conduit road to form hot water in negative pressure insulation water butt and under suction function, through diversion intubate tee pipe fitting, enters upper and lower conduit road and open water distribution triple valve, hot water is because siphonage can continuously flow out from shower nozzle.
The beneficial effects of the utility model be only on the basis of regular solar water heater, by changing the length of diversion intubate, increase tee pipe fitting, fill valvular ventilative pipeline, on upper and lower conduit road, install that manual suction pump can realize upper and lower conduit road emptyingly prevent freeze injury, and can directly use hot water, there is simple in structure, the saving energy, safe and reliable.
