Abstract

The utility model relates to an air discharge device of upper and lower water common pipeline of solar energy hot water heater which is an improvement on the basis of the prior art. The utility model comprises an upper and lower common pipeline, the utility model is characterized in that the upper and lower common pipeline enters a water storage box from the top part of the water storage box to the bottom part of the storage box, the upper and lower common pipeline at the top part of the water storage box is connected with a three-way connector in series, the third port of the three-way connector is connected with an air discharge pipe, moreover an air discharge valve is arranged at the end of the air discharge pipe. The utility model has reasonable design, simple structure, low cost and convenient application.

Description

A kind of solar water heater is water common conduit emptier up and down

Technical field: the utility model belongs to the solar water heater technology, relates to a kind of common conduit of water up and down emptier of solar water heater.

Background technology: solar water heater water common conduit emptier up and down can be discharged the water in the common conduit, help preventing and when avoiding winter, freeze in the water common conduit up and down to stop up, even the pipeline spalling is damaged, simultaneously can in time use hot water, and help preventing water resource waste.Solar water heater of the prior art is water common conduit emptier up and down, and its structure is more complicated all, and what have installs magnetic valve additional, and what have installs float-controlled valve additional.Install solenoid control mechanism additional, the one, because magnetic valve must be controlled in electricity consumption, moist because of all comparing usually in the bathroom again, the initiation electric shock accidents is easy to leak electricity; The 2nd, magnetic valve is the principle that adopts electromagnet, and its slideway partly is easy to be stuck, and cause control ineffective, and maintenance is relatively more difficult, needs to be undertaken by the professional, very trouble; The 3rd, the cost height, service life is short.Install the float-controlled valve controlling organization additional, first operation is too frequent, and a lot of people can not accomplish proper operation, behind tube emptying, still have ponding in the float-controlled valve, is easy to bursting by freezing winter and damages, even scrap; It two is that cost is also than higher.

Technology contents: the purpose of this utility model provides solar water heater a kind of simple in structure, cheap water common conduit emptier up and down, in order to overcome the above-mentioned drawback of existing in prior technology effectively.The utility model is to improve realization on the basis of existing technology, it comprises water common conduit up and down, it is characterized in that the water common conduit enters in the storage tank up and down above storage tank, bottom until storage tank, the top of storage tank is serially connected with a threeway on the water common conduit up and down, it is indoor that the 3rd termination of this threeway has an evacuated tube to introduce, and end is equiped with an exhaust-valve.During use, earlier the exhaust-valve of evacuated tube end is closed before the last water, a part of water enters in the evacuated tube by the 3rd end of threeway in the last water process.Behind the filling up water, close water supply valve, open the exhaust-valve of evacuated tube end, open hot water or shower switch then immediately, under siphonage, the water in water common conduit and the evacuated tube promptly flows out from evacuated tube up and down, thereby realizes the emptying of water common conduit up and down.During water, earlier the exhaust-valve of evacuated tube end and hot-water switch and shower switch are closed, open water supply valve, water common conduit bath up and down in short-term earlier, make and store up in the pipeline to close after a small amount of diversion, open hot-water switch or shower switch then, the hot water in the storage tank can be under the diversion gravity effect in the water common conduit up and down, flows out by water common conduit up and down.

The utility model design is more reasonable, relatively simple for structure, and cost is very cheap, and is very easy to use.

Description of drawings: accompanying drawing is a structural representation of the present utility model

The specific embodiment: accompanying drawing has provided a specific embodiment of the present utility model, with reference to the accompanying drawings, 3 is water common conduit up and down among the figure, water common conduit 3 enters in the storage tank 5 above storage tank 5 up and down, bottom until storage tank 5, the top of storage tank 5 is serially connected with a threeway 4 on the water common conduit 3 up and down, and it is indoor that the 3rd termination of this threeway has an evacuated tube 2 to introduce, and end is equiped with an exhaust-valve 1.

Claims

A kind of solar water heater is water common conduit emptier up and down, comprise water common conduit (3) up and down, it is characterized in that water common conduit (3) enters in the storage tank (5) up and down above storage tank (5), bottom until storage tank (5), the top of storage tank (5) is serially connected with a threeway (4) on the water common conduit (3) up and down, it is indoor that the 3rd termination of this threeway has an evacuated tube (2) to introduce, and end is equiped with an exhaust-valve (1).
