Abstract
The utility model relates to an antiscale solid-core detecting rod for a water level and water temperature, which is a device for detecting the water level and simultaneously for detecting the water temperature by an electrode type. Because a conductive rubber sleeve is arranged on a position detecting electrode and seal gum is poured in the detecting rod, the problems that the scale is formed on the electrode and dew is formed in the detecting rod are effectively solved. Thereby, the continuous service time of the detecting rod is extended. Especially, use effects are more obvious in a water heater with the big change of the water temperature.
Description
The utility model relates to a kind of electric pole type and measures water level, can survey the device of water temperature simultaneously.
Test bar in the bar type liquid level liquid temperature transmitter that known Chinese patent instructions ZL94235554.7 proposes, when in water temperature variation water heater greatly, using, because the inner chamber of its test bar is communicated with atmosphere, along with airborne moisture in the variation chamber of water temperature is separated out, on the wall of chamber, produce dewfall.So long-time the use can be gathered the electrical property that has destroyed test bar because of dewdrop, detects error and cause.Moreover, owing to adopt electrode mode sensed water level, can increase contact resistance because of the incrustation scale of tying one deck densification slowly on the metal electrode, particularly under the harder situation of water quality, can shorten the continuous service time of test bar.
The purpose of this utility model is that a kind of water-level and water-temperature test bar that can prevent to tie fine and close incrustation scale on the electrode and not produce dewfall will be provided.
The purpose of this utility model is achieved in that in the test bar chamber injects macromolecule polymeric material, as silica gel, polyurethane glue etc., forms real core test bar, avoids producing the dewfall phenomenon.On electrode, add the conductive rubber cover, utilize rubber and incrustation scale thermal expansivity than big-difference, thereby preventing that incrustation scale from putting at conductive rubber forms fine and close scale crust.
The utility model has solved the problem that bar type liquid level liquid temperature transmitter that ZL94235554.7 proposes in use exists, simple in structure, easy for installation, the characteristics that can survey water-level and water-temperature simultaneously that the while has kept also that it has.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural drawing of the real core water-level and water-temperature test bar of the antiscale that the utility model proposes.
Know that by Fig. 1 location electrode (8) is provided with conductive rubber cover (2), driving source electrode (4) is provided with conductive rubber cover (5).In the conductive rubber cover, cavity (3), (6) are arranged all.Variation conductive rubber with water temperature is enclosed within the breathing of cavity place and since rubber and incrustation scale thermal expansivity than big-difference, make incrustation scale not put the scale crust that forms densification at conductive rubber.Insulation tube (1) is isolated multistage location electrode (8) and driving source electrode (4) and is concatenated into test bar.Be full of casting glue (7) in the rod, make test bar become real plug.Because of being provided with temperature element (9) in the rod, so can survey water temperature simultaneously.Each electrode all send parts to be connected (not drawing among the figure) by the lead in the rod with change.
Claims (2)
1. the real core water-level and water-temperature test bar of antiscale is characterized in that location electrode (8) is provided with conductive rubber cover (2), and driving source electrode (4) is provided with conductive rubber cover (5), is full of casting glue (7) in the test bar.
2. the real core water-level and water-temperature test bar of antiscale according to claim 1 is characterized in that in the conductive rubber cover cavity (3), (6) being arranged all.
