Description

A kind of solar water heater jettison gear

Technical field

The utility model relates to a kind of solar water heater jettison gear, belongs to the solar energy water heater pipe technical field that discharges water.

Background technology

The solar water heater use amount is huge at present, when the great convenience user is to the hot water demand, also effectively saved a large amount of electric energy, safety and environmental protection, but in use, because current solar water heater jettison gear is arranged in the water room, thereby cause after using end, still retained a large amount of surplus hot waters in upper water and downcomer, because hot water in long-time pipe can not get using and heating, therefore very easily cooling, thereby cause when using hot water next time, after need at first the pipeline inner cold water being discharged, can there is hot water to flow out, so not only affected solar water heater hot water utilization rate, very large water resource and solar energy resources waste have also been caused, more seriously, the water that retain in Chang Yinguan winter and cause water and downcomer by bursting by freezing, having a strong impact on solar water heater normally uses.

Summary of the invention

The utility model purpose just is to overcome above-mentioned deficiency, and a kind of solar water heater jettison gear is provided.

For achieving the above object, the utility model is to be achieved through the following technical solutions:

A kind of solar water heater jettison gear, described solar water heater jettison gear is by upper bush, lower sleeve, water fender, location-plate, connecting rod, push rod, inlet duct, elastic bellows, discharge sump and driving mechanism form, described upper bush and lower sleeve are threaded connection, described location-plate lays respectively at upper bush and lower sleeve inside, location-plate is separately established drainage hole and locating hole, described locating hole and upper bush, lower sleeve is coaxial, described water fender is in upper bush by connecting rod, between lower sleeve, and side is separately established sealing ring, described connecting rod is located and can be slided up and down by locating hole, described connecting rod lower end separately arranges stage clip, in described stage clip upper end and lower sleeve, the location-plate lower surface offsets, lower end is fixed on connecting rod by the nut gear, the dash platform is separately established at described lower sleeve top, described inlet duct is arranged on the lower sleeve side, and with lower sleeve side angle be 30 °～60 °, by wireway, the air inlet nut, ball sealer and air inlet pipe form, wherein the wireway front end is connected with the air inlet nut by screw thread, and separately establish cross bar in wireway inside, described cross bar is by the wireway cross section center of circle one-body molded with wireway, described air inlet nut top arranges circular air inlet, described ball sealer is positioned at wireway and is placed in the cross bar top, its diameter is less than at least 2 millimeters of wireway internal diameters, be greater than 2 millimeters of air inlet diameters, described air inlet pipe one end is coated on the air inlet nut outside, the other end is higher than the solar water heater water tank top, described discharge sump is connected with the lower sleeve end by elastic bellows, the discharge sump bottom arranges the upper and lower mouth of a river, the inner setting push rod coaxial with locating hole, the push rod front end arranges top flat, described top flat and lower sleeve inside connecting rod end offset, described push rod is fixed in the discharge sump bottom and is connected with the driving mechanism of discharge sump outside by sealing mechanism.

Driving mechanism is that stay cord drives, air pressure drives or solenoid actuated.

This new structure is simple, easy and simple to handle, can effectively avoid after traditional solar energy water the problem of water in pipeline, save greatly the solar water use amount, also get rid of on the other hand the row of conduits cold water time, improve the hot water utilization rate, save water resource, and can effectively avoid winter because of the water pipe from freezing crack phenomenon that water in pipeline causes, extended solar water heater service life, simultaneously, meet the requirement that automatic solar water heater is automatically gone up water fully.
