Description
Technical field
The utility model belongs to the water appliance technical field, is specifically related to a kind of boiler water-level control apparatus.
Background technology
Along with people to the growing interest of drinking water quality and improving constantly of requirement, boiler has been widely used in the public places such as industrial and mining enterprises, public institution, machine-operated department and even family, it has health, advantage easily, and existing boiler generally is furnished with automatic water supply control device, and this brings great convenience to daily life.
Water-level control apparatus refers to carry out the control of high-low water level by the method for mechanical type or electronic type, can control solenoid valve, water pump etc., becomes automatic controller for water level or water level alarm, thereby realizes semi-automation or full-automation.
The mechanical open water heater water-level control apparatus can be divided into lever water-level control apparatus and vertical direct-drive type water-level control apparatus.The lever water-level control apparatus is by float mechanism activation lever one end, the other end backswing of lever, so that corresponding water supply mechanism stops to supply water, the lateral dimension of this water-level control apparatus is excessive, cause water tank often need be made as wide flat type structure, volume is large and heavy.Vertically the direct-drive type water-level control apparatus is the improvement for the lever water-level control apparatus, it arranges montant above float, there is sealing-plug the montant upper end, float float to drive montant and then so that sealing-plug is blocked corresponding water inlet position, so that stop to supply water, because montant is the upper end that directly is connected to float, causes the longitudinal size of this device excessive.
CN 102323830 A disclose a kind of water dispenser, boiler Superthin water level control device, comprise reserve tank, water inlet support plate and be positioned at float into water support plate below, the water inlet support plate is arranged on the upper end of reserve tank, has the inlet opening that is communicated with reserve tank on the water inlet support plate.Have recessed cavity on the float, be provided with the epirelief guide cylinder in the recessed cavity, be equipped with on the epirelief guide cylinder be used to the sealing-plug that is sealed into the water hole, water inlet support plate bottom is provided with the outer spacing collar that is enclosed within epirelief guide cylinder periphery, the bottom of protruding guide cylinder has directed cavity, and reserve tank is provided with the guidepost that matches with directed cavity.
Although the mechanical type water-level control apparatus is with low cost, control accuracy is relatively poor, and is oversize, and is not durable, and easily affects the normal operation of electrical equipment, causes the water heater fault.
The electronic type water-level control apparatus is controlled the water level height by the water level controller of electronic level switch and collocation, the electronic level switch principle is by electronic probe water level to be detected, by the water level detecting special chip signal that detects is processed again, when fluid to be measured arrives operating point, chip is exported high or low level signal, hydrous water level controller again, thus realize control to water level.
The electronic type water-level control apparatus does not need float mechanism and montant, outside machinery-free action, and resistant is durable, is not afraid of the floating thing impact, and arbitrarily angled installation vertically is equipped with certain anti-wave function, and traditional electronic control device control effect precision is high.But existing electronic type water-level control apparatus cost is higher.
The utility model content
In order to reduce the cost of water level controller, the performance of the controller of flooding the utility model discloses a kind of boiler water-level control apparatus.
A kind of boiler water-level control apparatus as shown in drawings, mainly comprises: probe base flange 1, be equipped with public water level probe 6, the low-level probe 7 of silicon rubber cup and T-shaped silica gel, high-level probe 4.
Water level probe 4,6,7 controls are water level up and down, and wherein public water level probe 6 is common ports, low-level probe 7 control low-water level, the upper water level of high-level probe 4 controls.
At high-level probe 4, public water level probe 6, low-level probe 7 tops probe inserted sheet 83,82,81 is housed, the probe inserted sheet arrives control circuit with the probe base electrical signal transfer.
High-level probe 4, public water level probe 6, low-level probe 7 are fixed on the probe base flange 1 by gland nut 21,23,22 respectively.
In an embodiment of the present utility model, public water level probe 6 and low-level probe 7 control water heaters begin water inlet.
In an embodiment of the present utility model, public water level probe 6 and high-level probe 4 control water heaters stop into water.
Respectively T-shaped isolation silica gel 31,32,33 is fixed on three probes by probe gland nut 21,22,23, avoids each probe and 1 conducting of probe base flange in the boiler use procedure, cause water level control malfunctioning.
In public water level probe 6 and low-level probe 7 protection silicon rubber cup 51,52 is housed, T-shaped silica gel 34,35 is avoided public water level probe 6 to contact under off working state with low-level probe 7 and is caused maloperation, causes burning out boiler.
In probe base flange 1 and boiler fixed connection place silica gel sealing ring 10 is housed, avoids because the boiler high-temperature steam overflows the damage electric wiring.
This water-level control apparatus has improved the water level control accuracy of boiler, with respect to existing electronic type water-level control apparatus, has reduced cost.
Description of drawings
Accompanying drawing is system construction drawing of the present utility model.
Embodiment
Embodiment 1
When the underwater in the water tank is reduced to lower water level, then low-level probe 7 bottoms break away from the water surface, i.e. the cut-off of electric signal between public water level probe 6 and the low-level probe 7 is under the effect of control circuit, control solenoid valve conduction or pump working, water heater begin water inlet.
Embodiment 2
When the rising of the water surface in the water tank is higher than upper water level, then the water surface is immersed in high-level probe 4 bottoms, i.e. electric signal conducting between public water level probe 6 and the high-level probe 4 is under the effect of control circuit, the cut-off of control solenoid valve or water pump stop, and water heater stops into water.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection domain of the present utility model.
