Description

The water-feeding controller of solar water heater

One, technical field

The utility model relates to a kind of water-feeding controller of solar water heater, especially has the water-feeding controller of the solar water heater of overflow pipe.

Two, background technology

The photo-thermal that solar water heater makes full use of sunlight is heated up by collection feedwater such as heat pipes, has obtained using widely.China is the most popular country of solar water heater, and wherein a large amount of uses is non-pressure-bearing type solar water heater.During water, after water tank completely holds, flow out by overflow pipe on this solar water heater, overflow pipe also is contained near the water water valve, and during last water overflow, manually the stop valve of water management is closed in the pass again.The relatively more low-grade solar water heater of this generic has utmost point vast market, and ten million family has supplied hot water.But regrettably water management needs the people to have an optimistic view of overflow pipe on it, and is a lot of because the boiling water carelessness causes valuable water source to run off in vain.

The automatic control of last water has had some costs to occur than higher scheme, as adopt the structure of the level sensor of magnetic valve, open water on the magnetic valve during last water, magnetic valve automatically shuts down water when water-level alarm, and this series products generally is not suitable for using the repacking of existing non-bearing type solar water heater.Also relatively more professional in the control, cost is higher.

Three, utility model content

The purpose of this utility model is: the water-feeding controller that a kind of non-bearing type solar water heater is provided, especially the water-feeding controller that has the solar water heater of overflow pipe, satisfy existing user's request, satisfy existing solar water heater user's repacking, and cost price is low, promotes to have very much meaning.

The utility model purpose is achieved in that the water-feeding controller of solar water heater, by the axle sleeve of assembling by spool, adhesive iron, pull-in winding, spring, installing plate, the switch of power supply and series connection constitutes, axle sleeve by fit on water stop valve spool, adhesive iron, pull-in winding, torsion spring, installing plate, the switch of power supply and series connection constitutes, axle sleeve is installed on the stop valve spool, one end and the axle sleeve of adhesive iron are fixed, the other end of adhesive iron drives stop valve switching spool water valve, and the other end of adhesive iron is pressed close at the position and the pull-in winding of heat water valve, spring is provided with fixing point on adhesive iron, the other end of spring is fixed; The pull-in winding and the switch of power supply series connection; Switch is a contact switch, is installed in the overflow pipe position; Adhesive iron, pull-in winding, spring are installed on the installing plate.

Torsion spring is provided with fixing point on adhesive iron, the installation site of torsion spring is to make moment make adhesive iron to closing the valve position rotation, the pull-in winding and the switch of power supply series connection; Can be provided with two switches, generally be made of contact switch, another switch is contained in the pass valve position of adhesive iron, generally also is provided with soft iron core in the pull-in winding, and is suitable in the hope of the suction of adhesive iron, is enough to overcome the moment of torsion spring (spring).

The course of work of the present utility model such as following: assembling is a long rod type structure by axle sleeve, the adhesive iron of spool, fix with axle sleeve, drive valve when adhesive iron sways or close valve, when driving valve, adhesive iron sway to drive valve position, spring is turned round, pull-in winding is lived the adhesive of adhesive iron, this adhesive moment is larger than spring torsion, after water tank is full, overflow pipe has water to overflow, and the switch that is contained in the overflow pipe place disconnects, and adhesive iron also disconnects, spring returns to original pass valve position, cuts off the water supply and power supply.Two equal adhesives of tandem tap make the coil electricity work of adhesive iron when driving valve.

Power supply generally is a dc source, adopt battery or supply convertor all can,

Characteristics of the present utility model are: simple in structure, during use power consumption low, adopt the 6-12V dc source get final product, electric current only needs tens milliamperes, the big better effects if of electric current provides a kind of switch that automatically shuts down water well certainly.Promptly be applicable to the supporting existing water heater of repacking that also is applicable to.

Four, description of drawings

Fig. 1 is the utility model structural representation

Installing plate 1, adhesive iron 2, pull-in winding 3, by axle sleeve 4, spring 5, power supply 6, switch 7,8, the lead 9 of spool, overflow pipe 10.

Five, the specific embodiment

As shown in the figure, the water-feeding controller of solar water heater, an end that is slightly larger than the pass valve moment of stop valve, torsion spring by the torsion moment of the axle sleeve of spool, adhesive iron, pull-in winding, spring (torsion spring) by assembling is limited to the gap position by the axle sleeve of spool, and a certain hole is fixed on the other end and the installing plate.Fixed position by regulating spring can regulating spring moment of torsion, power supply adopts AC converter (6-24V output, 150mA gets final product with interior) or battery all can.Embodiment chooses 6V and 60mA can hold adhesive iron 2 when driving valve.Especially two switches of connecting, remove one and be installed in overflow pipe position (also can be installed in the overflow water outlet on the water tank), the another switch is installed in the position after spring is replied, this switch supports the contact after adhesive iron 2 is opened the valve return and opens (disconnections), like this behind overflow place switch joint, this switch disconnection does not produce power supply.

The axle sleeve that is assemblied in water stop valve spool is used for turning on and close valve under the adhesive sheet iron strip is moving, and adhesive iron is the iron plate (iron) of 6-10cm, and pull-in winding adopts the enamel-covered wire coiling (diameter 0.1-0.2) of 1000-3000 circle, is built-in with soft iron core.The switch of pull-in winding, spring (torsion spring), series connection is installed on the installing plate.The axle sleeve that is assemblied in by spool passes installing plate, and adhesive iron is installed again, the position of the pass valve of the dotted line of adhesive iron, and solid line is out the position of valve.

The construction of switch that overflow pipe (return pipe) is located has multiple mode, as utilize the gravity switch or the buoyancy switch of backwater outflow effect, be provided with on the contact that a little water container is connected in switch, leaking hole is arranged at the water container bottom, also can be travel switch, the button of travel switch be backed down by current.Promptly switch cuts off and all can cut off pull-in winding when overflow, finishes the utility model function.

Axle sleeve is installed and is wanted on the stop valve spool, one end and the axle sleeve of an adhesive iron are fixed, the other end of adhesive iron drives stop valve switching spool water valve, the other end of adhesive iron is at the fixed-site pull-in winding of heat water valve, torsion spring is provided with fixing point on adhesive iron, the installation site of torsion spring is to make moment make adhesive iron to closing the valve position rotation, pull-in winding and two switches of power supply series connection; Two switches generally are made of contact switch, generally also are provided with soft iron core in the pull-in winding, and are suitable in the hope of the suction of adhesive iron, are enough to overcome the moment of torsion spring.
