Abstract

The utility model relates to a siphon type emptying device for water feeding/discharging pipes of a solar water heater, which belongs to an emptying and freezing prevention device for water heating pipelines. The siphon type emptying device mainly comprises a solar water tank, a siphon pipe is arranged in the water tank to lead out hot water, the extended part of the siphon pipe is divided into two sections, a water feeding/discharging pipe and an emptying pipe, the water feeding/discharging pipe is communicated with a mixed water valve and a cold water pipe and is then connected with a shower through a pipeline, and the end of the emptying pipe is provided with an emptying valve. The siphon type emptying device is characterized in that the pipeline of a water feeding/discharging pipe of the emptying pipe is connected with a pumping cylinder, and the pumping cylinder can only pump air in the water feeding/discharging pipe but can not charge air into the water pipe. When the water feeding/discharging pipe is emptied and hot water is needed, a user can pump part of air in the water pipe with the pumping cylinder to reduce air pressure in the water pipe, hot water in the water tank can flow into the water feeding/discharging pipe through the siphon pipe under the atmospheric pressure according to the siphon principle, and then when the user opens the mixed water valve, hot water can flow out of the shower, thereby realizing the purpose of discharging hot water once the shower is turned on.

Description

Solar water heater is used sewer pipe hydrocone type emptier

Technical field

The utility model relates to the evacuation and anti-freezing device of hot-water heating pipeline, specifically is solar water heater upper and lower conduit hydrocone type emptier.

Background technology

At present, all existing in the existing solar energy water heater device utilizes siphon principle to carry out the method for tube emptying, as shown in Figure 1, one pipe is set as siphon pipe in the water tank of solar water heater, siphon pipe the higher authorities connect two tubes by a threeway, the pipe of lower is connected with indoor water route valve as upper and lower conduit, and the pipe of eminence reaches indoor as evacuated tube, valve of the terminal connection of evacuated tube.When having the water existence water in the pipe need be discharged in the upper and lower conduit, open the evacuated tube valve, open the water route valve again, the water of upper and lower conduit will divide two parts toward dirty from peak, a part flows into water tank along siphon pipe, another part flows out along pipeline from indoor water route valve, and the water in the water pipe just is drained like this.But first problem that such structure exists is after emptying, when needing to use the hot water in the solar water container, at first to close the emptying valve, at this moment have only air in the upper and lower conduit, will mix water valve and open supreme water level and put, after needing the preceding paragraph cold water post, and then will mix water valve and open to going out the hot water position cold water is emitted, the cold water air pressure of emitting in the water pipe can reduce rapidly like this, is lower than atmospheric pressure, hot water in the water tank enters the upper and lower conduit road and flows out under the atmospheric pressure effect, just can use.Second problem is particularly in the vast rural area that does not have heating equipment, and cool water pipe is easy to be frozen winter, and existing hydrocone type emptying does not have cold water and just can't draw solar water, has caused hot water can't use yet.If the 3rd problem has U type pipeline to exist exactly, the part of U type pipeline will have certain water, and existing hydrocone type emptying can't be discharged water.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of cold water post that need not add just can draw hot water, and the solar water heater that is adapted at using in the various adverse circumstances is used sewer pipe hydrocone type emptier.

The technical scheme that the utility model technical solution problem adopts is, a kind of solar water heater is used sewer pipe hydrocone type emptier and is mainly comprised solar water container, siphon pipe is set in water tank draws hot water, siphon pipe after drawing is divided into two sections, upper and lower conduit and evacuated tube, upper and lower conduit connects mixed water valve and cool water pipe is communicated with, being communicated with the back links to each other with shower by pipeline, the emptying valve is installed in the termination of evacuated tube, it is characterized in that: connecting a pump bowl on the pipeline of described emptier upper and lower conduit, pump bowl can only be extracted the air in the upper and lower conduit out and can not charge into air in water pipe.

Described pump bowl is made up of barrel shell, valve, valve, piston, piston rod, piston handle etc., be pulled outwardly out the air in the piston extraction water pipe, propelling piston inwards, air in the inflator is compressed, valve blocks the valve mouth under gas pressure makes air can't enter water pipe, compressed air is extruded inflator from the piston periphery, draws to push away a piston and can finish once and bleed.

The O RunddichtringO is set on the described piston, is used to reduce the friction of piston and barrel shell, prolong the pump bowl life-span.

On described barrel shell, also be provided with discharge outlet, be used to get rid of the water that enters pump bowl.

The utility model is in emptying state and when need using hot water at upper and lower conduit, extract the air in the water pipe out a part with pump bowl, air pressure reduces in the water pipe, according to siphon principle, hot water in the water tank will enter the upper and lower conduit road by siphon pipe under atmospheric pressure, at this moment open mixed water valve, hot water just can flow out from shower, realizes once opening out hot water.

The beneficial effects of the utility model are not only to have solved the problem that solar energy upper and lower conduit road water causes the frozen pipe in winter after connecting a pump bowl on the pipeline of upper and lower conduit, thereby and solved simultaneously and must emit ducted a large amount of cold water waste water resource and the problem of time before solar water heater uses hot water, accomplish not freeze winter water pipe and once the effect of the hot water of turning on the tap out.
