Abstract

A siphon-type emptying device for the water up and down pipeline of a solar water heater relates to an emptying and anti-freezing device for a water heating pipeline. The device mainly comprises a solar water tank; a siphon pipe for pumping out hot water is arranged in the water tank; after hot water is pumped out, the siphon pipe is divided into two sections, namely, an water up and down pipe and an emptying pipe; the water up and down pipe is connected with a water mixing valve and communicated with a cold water pipe, and then is connected with a shower via a pipeline; and an emptying valve is mounted at the end of the emptying pipe. The device is characterized in that an air pump is connected on the pipeline of the water up and down pipe of the emptying device; and the air pump can only pump out air in the water up and down pipe, but cannot fill air in the water pipe. When the water up and down pipe is empty, and hot water is required, part of the air is pumped out via the air pump; the air pressure in the water pipe is reduced; according to siphon principle, hot water in the water tank enters the water up and down pipeline through the siphon pipe under the action of atmospheric pressure; and at this time, hot water can flow out from the shower through opening the water mixing valve, thereby realizing the purpose that hot water flows out as soon as the valve is opened.

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.
O type cushion rubber 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.
