Description

External solar water heater water controller

Technical field

The utility model relates to a kind of solar water heater, relates in particular to a kind of external solar water heater water controller that can realize water and pipe evacuation in the automatic control.

Background technique

Domestic solar water heater's water tank is provided with water injecting pipe and overflow pipe, and when water level reached the spilling water mouth of pipe, overflow pipe was toward the user side spilling water, and the user closes Water injection tap.The people can not leave during water filling, otherwise may cause the waste of water.The solar water heater manufacturer is arranged now, produce the secondary water tank of a kind of employing, secondary water tank directly is communicated with water pipe, establishes water-level control apparatus in secondary water tank, can realize a kind of solar water heater of automatic water supplement; The advantage of this solar water heater is to realize water level control, makes cistern water level be in setting height all the time; Shortcoming is that volume is big, and complex structure needs a multi-link water inlet, needs several jointings, and secondary water tank needs insulation.Be reduced to when subzero at temperature, great majority are to take the mode of the surplus water of emptying to protect the water pipe of solar water heater not to be damaged by frost.Present domestic solar water heater is that water pipe is freezing than the fault that is easier to occur, and some producer takes auxilliary heat of electricity or the empty device of solenoid valve control to solve the problem that water pipe is endured cold when design.Take this antifreezing measure user cost higher, the product price height, the life-span is short, the installation and maintenance trouble, it is few to accept equipped user.

The patent application of number of patent application 200610039790.x is at the problems referred to above for this reason, a kind of solution is provided, can realize water in the pipe evacuation of solar water heater and the automatic control preferably, but there is following defective, its pipeline exhausting device normality is an opening state, if make it closed, just need to use the control device of air to airbag aeration, closed water outlet makes it to expand, but because general closed time requirement is longer, the long-term rear gasbag that uses is aging, has phenomenons such as gas leakage, is difficult to guarantee the closed performance of air bag to water outlet, cause the water outlet of water, make turnover water pipe be full of water, be difficult to realize the real emptying of turnover water pipe, so await further improvement.

The model utility content

The utility model is at above-mentioned defective, and purpose is to provide a kind of external solar water heater water controller that can reliably realize water in pipe evacuation and the automatic control.

The technical solution of the utility model is: the utility model comprises water automatic control device and pipeline exhausting device, user side is provided with the control device of air that is connected with water controller, pipeline exhausting device comprises the air bag enclosing cover that is connected in valve body and the closure on the valve body, the valve body of pipeline exhausting device and turnover water pipe are communicated with, the water outlet of air bag enclosing cover and water tank is communicated with, be provided with in the air bag enclosing cover and control the air bag that device of air is connected, the air bag mouth contains a movable axis, movable axis is provided with valve, valve is arranged between water outlet of water tank and the turnover water pipe, the size of valve is between air bag enclosing cover and valve body, the square plate of perforate during valve body is provided with, square plate is arranged between valve and the turnover water pipe, and movable axis is arranged with spring outward, and spring is arranged between valve and the square plate.

The utility model has changed the working method of water controller, make the normality of pipeline exhausting device be in closed state, water controller is opened, can make no ponding in the turnover water pipe when so just having guaranteed not use, the real pipe evacuation of realizing, the working life of improving solar water heater.

Embodiment

The utility model comprises water automatic control device and pipeline exhausting device, user side is provided with the control device of air that is connected with water controller, pipeline exhausting device comprises the air bag enclosing cover 3 that is connected in valve body 8 and the closure on the valve body 8, the valve body 8 of pipeline exhausting device and turnover water pipe 18 are communicated with, the water outlet 6 of air bag enclosing cover 3 and water tank 1 is communicated with, be provided with the air bag 5 that is connected with the control device of air by tracheae 2 in the air bag enclosing cover 3, tracheae 2 is connected on the air bag enclosing cover 3 by capping 4, the air bag mouth contains a movable axis 11, movable axis 11 is provided with valve 7, valve 7 is arranged between water tank 1 water outlet 6 and the turnover water pipe 18, the size of valve 7 is between air bag enclosing cover 3 and valve body 8, the square plate 10 of perforate during valve body 8 is provided with, square plate 10 is arranged between valve 7 and the turnover water pipe 18, be arranged with spring 9 outside the movable axis 11, spring 9 is arranged between valve 7 and the square plate 10.

The water of going up of the present utility model is that the 200610039790.x or the patent No. are 200620072572.1 last water automatic control device from controlling device employing number of patent application, it comprises water supply valve body 12, ball float 13, valve piece 14, water supply valve bucket 15, Rectifier plate 16, water inlet 17, and concrete annexation is just no longer narrated.

During the utility model work, at first go up water, because under the effect of spring 9 elastic force, valve 7 is closed, water water from the last water automatic control device, when water level reached predetermined water level, float valve was closed, and last water is finished, when making water, give air bag 5 inflations, the size of air bag enclosing cover 3 of the present utility model is more bigger than air bag 5 sizes, when air bag 5 expands like this, it mainly expands to the axial direction of air bag enclosing cover 3, can better promote the motion of movable axis 11 like this, thereby open valve 7, realize water down, when water not, close the control device of air, valve 7 is closed under the elastic force effect of spring 9, offers closeable aperture on last water automatic control device, when not making water like this, open aperture, air is fed, realize emptying.

The relative patent application 200610039790.x of the utility model has following advantage; It has changed the working method of air bag 5, promptly by air bag 5 under normal conditions the time water controller be in opening state and become closed state, be fit to the actual needs that use so more, because solar water heater does not descend water when normality, just descend water during use, the problem that has caused with regard to having solved air bag 5 gas leakage like this, what make the utlity model has service behaviour more reliably.
