Abstract

An automatic water boiler for providing the boiling water is disclosed. After water is boiling in boiler, it is discharged into a thermal insulated water tank via hot water conveying pipe under the action of steam pressure and then a pressure limiting valve release the steam pressure. The cold water is supplemented to the boiler via the said pressure limiting valve, when the level of hot water in water tank reeches a predefined hight, a float ball can open the graviation valve to close the pressure limitng valve, stopping the water supplement of boiler. The water can also flow from the said water tank back to the boiler via the gravitation valve. The heat generated by the boiler can be controlled by the signal of closing float switch.

Description

Automatic water boiler

A kind of equipment of automatic supply boiling water

Prior art the general stove one that adopts of boiler burn; can only regularly supply boiling water; people can not beat and take away water in the process of heating up water; after the boiled truce of one stove water; boiling water temperature in the boiler also can reduce gradually; add that to heat up water and add cold water all be artificial control, people beat the often hot water of getting just, infuse tea or also often need to heat when drinking again.

Though hot water storage box of the usefulness that also has and boiler water are separately, people can beat at any time and take away water, but because hot water storage box water stopping after full burnt and since the heat-insulating property of hot water storage box before inevitably heat radiation and blow-on in second day are heated up water the surplus water of water tank cause the temperature of boiling water also can reduce.

Supply at any time for boiling water, and solve hot water storage box and reach behind the designated water level boiler and continue the thermotropism water storage box and replenish suitable heat, temperature with boiling water in rising or the maintaining heat water storage box, make the user can play the boiling water of getting nearly boiling point at any time, we have designed this automatic supply boiling water equipment, as shown in Figure 1, because the acting in conjunction of weight valve and pressure limiting valve, make water in the boiler reach under the effect of steam pressure, can only to go out pipe behind the boiling point and enter the heat preservation hot water storage box by boiling water, steam pressure in the boiler is also drained by this pipe afterwards, running water adds cold water to boiler automatically by pressure limiting valve again, when the water level of heat preservation hot water storage box reaches setting height, big ball float is with the weight valve pull-up, heat preservation hot water storage box and boiler are communicated with, pressure increases in the boiler, pressure limiting valve stops into water, steam in the boiler behind the boiling point just can enter in the heat preservation hot water storage box by gravity valve and be absorbed liquefaction by water, and then improve and kept water temperature in the hot water storage box, water in the hot water storage box also can enter boiler by gravity valve simultaneously, and the caliber size of communicating pipe and gravity valve should be able to satisfy above-mentioned condition.

In order to reduce the volume of big ball float, available floating ball lever is with the weight valve pull-up, and also available ball-cock assembly or magnetic valve replace weight valve.

Pressure limiting valve utilizes the structure and the principle manufacturing of liquefied gas cooker pressure limiting valve, and as shown in Figure 2, pressure limiting valve should be able to make boiler water reach height h to the pressure P of boiler input water, and h satisfies condition ₁＜h＜h ₂, h ₁Be the height of communicating pipe and boiler interface, h ₂Height for the gravity valve port.Like this, pressure limiting valve can carry certain pressure to guarantee to supply cold water to boiler to boiler, and boiler water overflows into boiler when having prevented artificial pull-up weight valve again, and boiler water backflow pressure limiting valve plays the non-return valve action in the time of preventing that the boiler internal pressure from increasing simultaneously again.

Pressure limiting non-return principle according to pressure limiting valve, the also available float-controlled valve serial connection of pressure limiting valve check valve replaces, as shown in Figure 3, float-controlled valve utilizes the principle of motor vehicle carburetor bowl to manufacture and design, and for attractive in appearance and commercialization, float-controlled valve can satisfy under the situation of adding the cold water needs to boiler, volume should reduce as far as possible, should be complementary with boiler, when float-controlled valve was installed, its liquid level h also should adjust and be installed in h ₁＜h＜h ₂Between, like this, both having guaranteed to supply cold water to boiler, boiler water overflows into boiler in the time of preventing manpower pull-up high pressure weight valve again, the easy also ball-cock assembly water tank replacement float-controlled valve of available toilet of making.

The first manually pull-up weight valve of boiler fills of giving, so that in adding the water process, get rid of the air in the boiler, in use, people can stop to add cold water to boiler by manual at any time as required pull-up weight valve, when people's night's rest, boiler is banked up a fire when operation, but also pull-up weight valve, so that reduce the boiling water amount of holding and keep water temperature, also help the boiling water of supply in second day near boiling point.In addition, when the water temperature in the user feels the heat preservation hot water storage box is not high, but the pull-up weight valve, stopping into water, and the feed-tank additional heat.

The boiler that this equipment is suitable for, can be coal-fired, fuel oil, various forms of boilers such as combustion gas, capacity also can be designed to different specifications, behind big ball float pull-up weight valve, the switch closure, the full indicator lamp of water is bright, at this moment fuel oil, the boiler of combustion gas can be controlled the caloric value of boiler automatically with this signal, for the lower coal-burning boiler of automaticity, available artificial method, according to the difference in season, adjust air door to suitable position, can utilize this signal to control the electromagnetism air door for the higher coal-burning boiler of automaticity, air door is reduced to automatically according to the correct position that pre-sets season, if use the cupola-type efficient briquette stove (application number 00123759.4, publication number CN1316618A) of my design invention, the thermal efficiency and automaticity can be higher.

In order to improve the heat-insulating property of hot water storage box, but the heat-insulation layer filled phenolic foam plastics between water tank and the shell, boiler continues to the certain heat of water tank output after reaching setting height with the hot water storage box of excellent thermal insulation performance and the continuous boiling water output of boiler and cistern water level, make the boiler of the present invention and prior art compare, automatically supplied the difficult problem of boiling water temperature by nearly boiling point in 24 hours except that having solved whole day, also can make the user select the volume of boiler for use, capacity reduces greatly, thereby cost is reduced, the thermal efficiency improves, and uses the boiler of 200 liters of alternative three capacity that burn on the one of port of Φ 120mm honeycomb briquette as a cover.
