Description
Technical field
This utility model relates to a kind of water treatment facilities, is specifically related to a kind of water treatment facilities water level probe.
Background technology
The water lev el control of water tank be common are following several ways: float-ball type, photo-electric, pressure type and water level probe formula.Due to float-ball type, to there is cost in photo-electric, pressure type high, and structure is complicated, and moving component such as easily breaks down at the defect, and seldom application in water treatment facilities, water level probe formula is modal in water treatment facilities.
Water level probe, detects for cistern water level.In water treatment facilities, water vaporizes when high temperature, water, vapour consume relatively big, to constantly supplement water so that the water in water tank keeps certain height.The purposes of water level probe is the height of sensed water level, understands the water level in water tank at any time.
The control principle of water level probe is: apply the DC voltage of a control signal on water level probe, using water tank as negative electrode, in the middle of water tank, unsettled water level probe is anode, and after the water level of water tank goes up, water touches anode, water is electric conductor, so anode and cathode has just become path, and the voltage on water level probe produces change, and this change in voltage is exactly level control signal, after this signal is processed by controller, the supplementary water of water tank is controlled.
When using the control mode of water level probe, there is anode, catholyte corrosiveness in the electrode owing to using, water level probe is corroded, sensitivity decrease, particularly in boiler, electrolytic etching and the surface scale of water level probe are even more serious, occur that water level phenomenon out of control often occurs, the enterprise producing water treatment facilities adds workload and the cost of maintenance and repair, and the user of water-suppling treatment equipment makes troubles.
Summary of the invention
The purpose of this utility model is to overcome existing water treatment facilities technical deficiency, it is provided that a kind of water treatment facilities water level probe, water level probe surface is less scaling.
The technical scheme of this utility model purpose is: a kind of water treatment facilities water level probe erosion protection system, described water treatment facilities include boiler, electrothermal tube, it is characterized in that being provided with bottom described boiler a water tank inlet, described water tank inlet is provided above a dividing plate, and described electrothermal tube is positioned at above dividing plate, and described boiler is connected with water level detecting pipe by water tank connecting pipe, described water tank connecting pipe is positioned at below dividing plate with the connector of boiler, sets water level probe in water level detecting pipe.
According to preferred embodiment of the present utility model, water level probe includes fixing probe, low-level probe and high-level probe.
According to preferred embodiment of the present utility model, the holding wire of described water level probe is connected with signal transceiver, and described signal transceiver launches pulse signal.
According to preferred embodiment of the present utility model, the caliber of water tank connecting pipe is 5 ~ 8mm.
Effective to boiler and water level detecting water tank connecting pipe is connected together by this utility model, and the height of water level in water level detecting pipe is exactly the height of water level in boiler.During moisturizing, entering in water level detecting pipe is supplementary cold water, the caliber of water tank connecting pipe only has 6mm, it is cooled that a small amount of hot water in boiler flows into water level detecting Guan Shiyi, so the water temperature in water level detecting pipe is typically normal-temperature water, water level probe surface is less scaling, and the sensitivity making water level probe is unaffected.This utility model can delay probe to corrode, and simple in construction is easy for installation.Water treatment facilities and boiled water machine that applicable water tank controls use.This utility model uses common stainless steel material SU304 draw point as detection electrode, and the water level that can be used in water treatment facilities cold water storage cistern and boiler automatically controls, and safeguards very convenient, the advantage such as mechanism is simple, anticorrosion.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Fig. 1 is principle schematic of the present utility model.
In figure: boiler 1, electrothermal tube 2, water tank inlet 3, water tank connecting pipe 4, water level detecting pipe 5, fixing probe 6, low-level probe 7, high-level probe 8, water level probe 9, signal transceiver 10.
Detailed description of the invention
As it can be seen, water treatment facilities water level probe erosion protection system includes boiler 1, water tank inlet 3, having electrothermal tube 2 for heating drinking water in water tank, boiler 1 and water level detecting pipe 5 are connected together by water tank connecting pipe 4；Water level probe 9 loads above water level detecting pipe 5 and is fixed on water level detecting pipe 5；The holding wire of water level probe 9 is connected with signal transceiver 10.
nullWhen using this utility model，Principle by U-shaped communicating pipe，Water level in boiler 1 and water level detecting pipe 5 is equal，From water tank inlet 3 entrance is supplementary cold water，Major part is in boiler 1，Sub-fraction flows in water level detecting pipe 5，So being normal-temperature water in water level detecting pipe 5，When the electrothermal tube 2 in boiler 1 heats，Heat is communicated up，Electrothermal tube 2 water temperature below is not heated，Volumetric expansion after the water heating of boiler 1，Water level slightly raises，Principle by U-shaped communicating pipe，Keep water level equal，In boiler 1, electrothermal tube 2 drinking water that is the most heated or that slightly raise below is pressed in water level detecting pipe 5 by water tank connecting pipe 4，Owing to the caliber of water tank connecting pipe 4 only has 6mm，A small amount of hot water in boiler 1 flows into during water level detecting pipe 5 the most cooled，So the water temperature in water level detecting pipe 5 is typically normal-temperature water，Water level probe 9 surface is less scaling，The sensitivity making water level probe 9 is unaffected.
During water level detecting, the pulse signal controlled by computer controller, differentiate the height of water level to the fixing probe 6 in water level probe 9 and low-level probe 7, fixing signal intensity between probe 6 and high-level probe 8 by signal transceiver 10, high and low water level can be differentiated at different periods by the signal between three pins.The positive inverted burst signal that water level probe uses computer chip to control controls, the height of water level is differentiated by fixing probe and low-level probe, fixing signal intensity between probe and high-level probe, owing to detectable signal is AC signal, there is not fixing anode and negative electrode, resistance to corrosion is greatly improved.Use this utility model, overcome the drawback of average probe, it is achieved that intelligent water level security control, logic decision, prevent as average probe occur make moist wait judge by accident fault.
