Abstract
The utility model discloses an empty-draining device for pipeline of pressurized water heater, comprising a water inlet pipe and a water outlet pipe, the top end of the water inlet pipe is a water inlet bending pipe higher than water level on water tank, the top end of the water outlet pipe is a water outlet bending pipe higher than water level on water tank, the other end of the water outlet bending pipe is connected with the water outlet of the water tank, the other end of the water inlet bending pipe is connected with the water inlet of the water tank, the top ends of the water inlet bending pipe and the water outlet bending pipe is provided with a check valve. In the utility model, as the top ends of the water inlet bending pipe and the water outlet bending pipe are higher than water level on the water tank, water can be stopped rapidly when stopping hot water or draining empty, a check valve for drain is arranged to make water in the pipeline be rapidly drained empty, therefore temperature-retaining measure is not necessary to be taken, the utility model can operate normally in winter and can effectively prevent the pipeline from being frozen. Moreover as cold water is not to be stored in the pipeline, the discharge water is hot water actually, the utility model has convenient application and can avoid waste. The utility model has convenient application and no operation malfunction, and is a high performance low-cost novel empty-draining device.
Description
Technical field the utility model relates to a kind of solar water heater emptier, relates to a kind of pressure-bearing type solar water heater pipeline exhausting device specifically.
Advantages such as the background technology pressure-bearing type solar water heater is because sturdy and durable, and is easy to use are very popular.But use pressure-bearing type solar water heater to exist the problem that winter, pipeline freezed at north cold area.The method of head it off is mainly used technology such as ribbon heater, zero degree intelligent switch in the prior art, though these technology can solve the pipeline frozen problem, all has drawback.As: when temperature was low especially, the ribbon heater was ineffective sometimes, if run into power failure then can't use, and the ribbon heater is caused solar pipe well fire easily; The intelligent switch performance is understable, as runs into power failure and then can bring a lot of troubles; No matter be technology such as ribbon heater or intelligent switch, all need the electrification resource, increase use cost.In addition, these methods all exist pipeline to have the problem of cold water at present, when using hot water, need bleed off the cold water in the pipeline earlier, promptly waste water, and lose time again.
It is a kind of simple in structure, with low cost that the summary of the invention the purpose of this utility model is to provide, and without electric energy, no pipeline cold water can effectively prevent the pressure-bearing type solar water heater pipeline exhausting device that pipeline freezes.
The purpose of this utility model is to realize by following technical scheme:
A kind of pressure-bearing water heater pipeline exhausting device, comprise water inlet pipe and outlet pipe, its structural feature is: said water inlet pipe top is the water inlet bend pipe that is higher than water level on the water tank, said outlet pipe top is the Discharging bent-tube that is higher than water level on the water tank, the other end water receiving case delivery port of this Discharging bent-tube, the other end water receiving case water inlet pipe of this water inlet pipe, the top of said water inlet bend pipe and Discharging bent-tube all is equipped with check valve.Because the top of water inlet bend pipe and Discharging bent-tube all is higher than water level on the water tank, purpose is that sealing is rapid when stopping hot water or emptying, and the effect that check valve is installed is when stopping into water, the water emptying rapidly that water inlet pipe epimere and outlet pipe are interior.
The horizontal mozzle to the water tank other end of packing in the said tank inlet pipe, the water outlet port of this horizontal mozzle is the inclined-plane port.Can the slow down mixed water speed of hot and cold water of mozzle is installed, and the inclined-plane port can prevent effectively that the water outlet port from withstanding on the water heater end face, reduces into water resistance.
Between water inlet pipe and outlet pipe, connect pipe, go up this communicating pipe magnetic valve is installed.When tap water cut-off, open magnetic valve, the water in the water tank can be emitted use.
Triple valve is installed on interior conduit, and this triple valve connects running water pipe, solar energy water inlet pipe and emptied of water respectively and chews.When running water and water inlet pipe connection, emptied of water is chewed end and is closed, when running water and water inlet pipe were closed, it is logical that triple valve epimere water inlet pipe and emptied of water are chewed termination, and indoor hot water nozzle is in the normally open position, connect the running water instant-heating and outlet hot, close running water, the emptying of hot-water line nature, winter is when using, emptied of water chewed open, but the water emptying in the water inlet pipe triple valve epimere.
Water tank end face at water heater is installed insulation cover, and said water inlet pipe and outlet pipe are installed in this insulation cover.
Advantage of the present utility model is: the utility model is because the top of water inlet bend pipe and Discharging bent-tube all is higher than water level on the water tank, sealing is rapid when stopping hot water or emptying, the check valve that emptying is used is all installed in extreme higher position at water inlet bend pipe and Discharging bent-tube, makes the rapid emptying of water in the pipeline.So need not take the insulation measure, pressure-bearing type solar water heater is normally moved winter, prevent that effectively pipeline from freezing.And owing to do not deposit cold water in the pipeline,, outlet pipe is hot water so emitting, easy to use, avoid waste.And the utility model need not be installed safe stopping means, and solar water heater does not have the harm that the high temperature superpressure is damaged.The utility model during without hot water water heater be passive state.The utility model is easy and simple to handle, and is easy to use, and no operation troubles is a kind of novel emptier of high-performance and low-cost.
The further advantage of the utility model is: can the slow down mixed water speed of hot and cold water of mozzle is installed, and leaving water temperature is stable.When tap water cut-off, or during insufficient pressure, open magnetic valve, the water in the water tank can be emitted use.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of insulation cover among Fig. 1.
The specific embodiment such as Fig. 1, shown in Figure 2, a kind of pressure-bearing type solar water heater pipeline exhausting device, comprise water inlet pipe 8 and outlet pipe 5, water tank 1 end face at water heater is installed insulation cover 9, be insulation material in water tank wall and the insulation cover, said water inlet pipe and outlet pipe are installed in the insulation cover, the water inlet pipe top is the water inlet bend pipe 7 that is higher than water level on the water tank, the outlet pipe top is the Discharging bent-tube 3 that is higher than water level on the water tank, the other end water receiving case delivery port 2 of this Discharging bent-tube, the other end water receiving case water inlet pipe 6 of this water inlet bend pipe, check valve 4 all is equipped with on the top of said water inlet bend pipe and Discharging bent-tube, the horizontal mozzle 12 of packing in the said tank inlet pipe to the water tank other end, laterally the water outlet port of mozzle is an inclined-plane port 13, connects pipe 11 between water inlet pipe and outlet pipe, goes up this communicating pipe magnetic valve 10 is installed, triple valve is installed on interior conduit, and this triple valve connects running water pipe respectively, solar energy water inlet pipe and emptied of water are chewed.
