Description

Solar water heater emptying control device

Affiliated technical field

The utility model relates to a kind of control device, relates to the solar water heater emptying control device of a kind of pipeline control that is used for solar water heater, draining, emptying specifically.

Background technology

Because solar water heater is saved the energy, does not have any pollution, and is economical and practical, safe and reliable, so be widely used, electric power resource is comparatively nervous now, so, promote the use of solar water heater and not only have certain economic benefits, and have the certain social benefit.But solar water heater in use exists some problems, water and emptier are to adopt manually-operated gate basically on the solar water heater at present, water tank water completely adopts alarm equipment alarm, use the manual-lock valve after the warning again, the poor reliability of a lot of alarms, so just cause easily report to the police untimely, thereby cause solar water heater can not stop automatically on water and the phenomenon that occurs metalling run out, can forget valve-off because of carelessness after sometimes going up water, the serious phenomenon of metalling run out occur; When needs use hot water, must get rid of the cold water in the pipeline earlier, just can emit hot water, this promptly wastes water and loses time; Because north of china in winter is colder, the outdoor pipeline of solar water heater freezes easily, improper use can cause water heater to damage, for solving the pipeline frozen problem, main method has thickening pipeline heat-insulation layer, or on pipeline, twining method such as heat tape, these class methods can not fundamentally solve the pipeline frozen problem, and use inconvenient, the cost height, the life-span is low.On the market pipeline exhaust-valve is arranged also now, but great majority exist complicated operation, the shortcoming of poor stability.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of solar water heater emptying control device, and this apparatus structure is simple, and serviceability is reliable, easy operating, and the water saving power saving, long service life, with low cost.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar water heater emptying control device, comprise a direct current slow speed motor and the ceramic core valve that is installed on the water heater pipeline, its structural feature is: on this direct current slow speed motor pinion is installed, Valve with ceramic core gate control end connects the gear wheel with pinion, the fixing rod that is communicated with in this gear wheel upper surface, be provided with by the inboard of normally-closed contact I that is communicated with rod control and normally-closed contact II and be connected lead, this connection lead connects motor one end, and the positive and negative electrode of power supply meets O and O respectively ₁, the opposite side of normally-closed contact I and normally-closed contact II meets B and A respectively ₁, A that the other end of motor is connected together in succession and B ₁Two ends, OAB and O ₁A ₁B ₁Form bidirectional relay with control end.Connect power supply during work, the relay control end disconnects, at this moment OA and O ₁A ₁Connect, relay A end is positive polarity, A ₁End is negative polarity, the positive polarity power supply is added to an end of motor, the negative polarity power supply is added to the other end of motor by normally-closed contact II, at this moment, gears engaged is passed through in the motor counter-rotating, driving gear wheel and the connection rod above the gear wheel just changes, forward to when this normally-closed contact is disconnected when being communicated with rod, motor stops operating, valve closing; When the relay control end is connected circuit, OB and O ₁B ₁Connect, this moment, the B point was anodal, B ₁Point is for negative pole, and by normally-closed contact I positive and negative power supply is added on the motor, and motor is just being changeed, and makes gear wheel and is communicated with the rod counter-rotating by gears engaged, forwards to when this contact is disconnected when being communicated with rod, and motor stops operating, valve open.Relative position by two normally-closed contacts has determined the angle that motor rotates, and the ceramic core valve rotates 90 degree and gets final product.

Be installed in by the valve of motor, gear wheel, pinion and control circuit control on the outlet pipeline in the heat-insulation layer of warming solar energy bucket outside.

Said heat-preserving container both upper ends thereof is respectively equipped with passage and water inlet pipe, and water inlet pipe and outlet pipe are communicated with water-supply-pipe, connects the auxiliary exhaust pipe on the water-supply-pipe on water inlet pipe, and the other end of this blast pipe is connected to the water-supply-pipe bottom.When adding water,,, after the topped up with water, can drain the water in water-supply-pipe and the blast pipe, prevent from winter to freeze stifled so water enters heat-preserving container from water-supply-pipe and blast pipe through water inlet pipe because control valve is not opened.During use, power up the relay control end, at this moment valve open, hot water is flow in the water-supply-pipe by outlet pipe, this moment, the effect of blast pipe was exactly that the air in the water-supply-pipe is upwards discharged, air enters heat-preserving container through drainpipe, water inlet pipe, discharge through steam vent again, it is indoor that water in the heat-preserving container flows to the user soon like this, if disconnect the relay control end, this moment, control valve was closed, and the hot water in the water-supply-pipe drops to the user naturally under the help of water inlet pipe and steam vent indoor, making does not have the existence of water in water-supply-pipe and the blast pipe, prevents from winter to freeze stifled.

The beneficial effects of the utility model are, use the utility model, the user only need when the needs water, press switch by switch, motor is opened valve automatically, hot water is directly discharged from solar water container, and the water that the user receives is directly for hot water, efficiently solves present user and uses and need problem that the cold water in the pipeline is discharged before the hot water, easy to use, water-saving result is obvious; When without hot water, by closing switch, the motor automatic-closing valve, the automatic emptying of the water in the pipeline reaches the purpose of evacuation and anti-freezing, uses simple and convenient; Owing to use electronic ceramic core valve, be difficult for blocking up, anti-90 ℃ hot water, wearability is good, can use at least more than ten thousand times; Because auxiliary evacuated tube has been installed, so when discharging water, if air is arranged in the hydraulic pipeline, air can be discharged by auxiliary evacuated tube, the phenomenon that avoid putting not water outlet takes place, and has further improved the serviceability of water heater; The utility model is simple in structure, and is with low cost, easy to use, and power consumption is little.
