Abstract
The invention discloses a water boiler liquid level detection device with high reliability, in order to solve the problem that the conventional liquid level detection device breaks down frequently. The device comprises a cylindrical outer shell which is vertically installed at one side outside a water tank of a water boiler, and the lower end of the cylindrical outer shell is communicated with a liquid level detection opening at the bottom of the water tank of the water boiler through a U-shaped tube; and the cylindrical outer shell is internally provided with a liquid level sensor. According to the invention, the cylindrical outer shell is communicated with the liquid level detection opening at the bottom of the water tank of the water boiler through the U-shaped tube, because the U-shaped tube is lower than the water tank of the water boiler, the density of the water in the water tank is lowered after the water is heated and the water can not be mixed and exchanged with cold water in the U-shaped tube, the water in the cylindrical outer shell is always cold and the liquid level sensor installed in the cylindrical outer shell can not be scaled; therefore, the reliability of the liquid level sensor is improved, the normal operation of the water boiler is ensured and the accident hazard is eliminated.
Description
Technical field
The present invention relates to a kind of interior water level of water tank device just that is used to detect boiler, belong to the detection technique field.
Background technology
Boiler is a device of supplying drinking hot water for people; Cross dry combustion method when low for preventing the heater in the boiler at anhydrous or water level; Cause boiler to damage even initiation fire; Boiler generally all is provided with liquid level detection device, has only when liquid level detection device detects water level and is higher than setting value, and heater could heat water.Existing liquid level detection device has multiple, but its liquid level sensor all will contact with the hot water in the boiler, because running water contains a large amount of calcium ions and magnesium ions, silt and various bacterium; Calcium ions and magnesium ions is separated out from water when being heated to more than 50 ℃; Mix with the silt in the water, various bacterium, generate a kind of sediment of white, thereby heater can be born stone incrustation scale on the liquid level sensor after use a period of time; And the high more incrustation scale of temperature is many more; This layer incrustation scale can reduce the accuracy of detection of liquid level sensor, also possibly cause faulty sensor when serious, causes safe and healthy hidden danger.Therefore, design a kind of boiler liquid level detection device of high reliability,, guarantee that user's property and personal safety is significant for the service life that prolongs boiler.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of boiler liquid level detection device of high reliability is provided, guarantee the safe operation of boiler.
Problem according to the invention realizes with following technical scheme:
A kind of boiler liquid level detection device of high reliability; Comprise a cylindrical case in the formation; Said cylindrical case vertically is installed in the outside side of boiler water tank, and its lower end is communicated with the Level Detection mouth of boiler water tank bottom through U type pipe, in the cylindrical case set inside liquid level sensor is arranged.
The boiler liquid level detection device of above-mentioned high reliability, said liquid level sensor is provided with a plurality of, and they are along the cylindrical case axial distribution.
The boiler liquid level detection device of above-mentioned high reliability, said liquid level sensor are dry-reed, Huo Ershi or electric pole type.
Cylindrical case of the present invention is communicated with the Level Detection mouth of boiler water tank bottom through U type pipe, because U type pipe is lower than the boiler water tank, the water in the water tank is heated back density to be reduced; Can not exchange with the cold water mix in the U type pipe; Thereby the water temperature in the cylindrical case is always lower, and just being installed in like this on the liquid level sensor in the cylindrical case not can scaling, thereby has improved the reliability of liquid level sensor; Guarantee the operate as normal of boiler, eliminated accident potential.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a structural representation of the present invention.
Each label is among the figure: 1, water tank; 2, cylindrical case; 3, liquid level sensor; 4, U type pipe; 5, water inlet pipe; 6, heater; 7, water.
The specific embodiment
The present invention improves reliability through the generation that suppresses incrustation scale, realizes through following several kinds of key measures; The one, the temperature of water can not be too high in the checkout gear, preferably normal-temperature water or cold water.The 2nd, water must flow in the checkout gear, can not be stagnant water.The 3rd, checkout gear must be connected with tested container.For this reason, below water tank 1 and cylindrical case 2, U type pipe 4 is set, water tank 1 is communicated with cylindrical case 2 by U type pipe 4.
The peak level of the bottom transverse of the cylindrical case 2 among the present invention should be also lower than the lowest water level of the Level Detection mouth of boiler water tank 1 bottom, so just can reach reasonable effect.
Referring to Fig. 1, the operation principle of this device is following:
1, when in the water tank 1 when anhydrous, inlet valve is opened, and water gets into water tanks 1 through 1 bottom water inlet pipe 5 in the water tank, and liquid level constantly rises.Because cylindrical case 2 is connected through U type pipe 4 with water tank 1, is equivalent to linker, so the water level in the cylindrical case 2 also rises steadily, reaches the purpose of water level detecting.Therefore also not heating of heater 6 time is so be normal-temperature water this moment in the cylindrical case 2.
2, after the level sensor in the cylindrical case 2 detects certain water level, heater 6 begins heating, the light specific gravity of hot water; Slowly rise to the top of water tank; And the low water of temperature still is in the bottom of water tank, because U type pipe 4 positions are lower than water tank 1, its inner cold water density is big; Can not mix exchange with the hot water in the water tank 1, realize the hot and cold water isolation.After the water in the water tank 1 is heated to uniform temperature, in the time of need adding cold water, because cold water is to add in the bottom of water tank; And its density is bigger, the hot and cold water meeting AUTOMATIC ZONING in water tank 1, and cold water is following; The water that gets in the cylindrical case 2 remains cold water, and hot water can not advance in the cylindrical case 2.Owing to after cold water additional be reduced to uniform temperature, stop moisturizing, begin the heating of next circulation when water tank temperature.
3, after water in the water tank is full, get into the insulation program, though the temperature of the interior water of heater water tank this moment can raise, the proportion of water is bigger in the U type pipe 4, and hot water still can not be with the exchange of the water in the U type pipe 4, and U type pipe 4 interior water temperatures can not rise.
4, when water tank 1 discharges water, the water in the cylindrical case 2 also can get into water tank 1 through U type pipe 4, and the interior water level of water level and water tank reduces synchronously in the cylindrical case 2, realizes the normal detection of water level.Mend fresh water cylindrical case 2 in again when intaking next time.
