Abstract
The utility model provides an electric contact water level measuring tube which can make an electric contact water level gauge correctly display the water level in a pressure vessel. The utility model is characterized in that the water side of a water level measuring tube is provided with a saturated steam heating device. When the utility model is used for a station boiler, the higher the rated working pressure is, the better superiority the utility model has.
Description
The utility model relates to the electric contact point fluviograph that is used for thermal measurement.
Electric contact point fluviograph is the difference with electric contact water level measuring cylinder (hereinafter to be referred as water level measuring cylinder) vapour, water side electric contact resistance value, by the water level display indicated water level.When being connected with pressure vessel, the vapour side of water level measuring cylinder is a saturation temperature, vapour, below the water termination, because radiation loss, water temperature descends gradually, and the corresponding increase of the severe of water, this is lower than the water level in the pressure vessel and causes negative error with regard to the water level that makes water level measuring cylinder.Pressure in the pressure vessel is high more, and negative error is big more; Under rated pressure, the water level in the pressure vessel is high more, and negative error is big more.So exist this possibility: for keeping " normally " water level, when normal operation, pressure vessel often is in higher level; What is more, and when the full water accident took place, the table meter was shown as not full water.This is a big hidden danger of safety in production.
The purpose of this utility model provides a kind of water level measuring cylinder, makes electric contact point fluviograph at the following water level that can both correctly show in the pressure vessel of any operating mode (being any pressure and any water level).
Design of the present utility model is with the saturated vapor heating, makes the following water maintenance saturation temperature in carbonated drink interface in the water level measuring cylinder, thereby reaches the purpose that can both correctly show the pressure vessel water level under any operating mode.For this reason, the utility model is the electric contact water level measuring cylinder that a kind of water that makes the water side that is used for thermal measurement keeps saturation temperature, it is characterized in that being provided with the saturated vapor heater in the water side of water level measuring cylinder.
Compared with prior art, the utility model has solved electric contact point fluviograph always can not correctly not show the pressure vessel water level under any operating mode problem, has eliminated the hidden danger that the water level accident takes place owing to electric contact point fluviograph is incorrect.
Accompanying drawing is the structure chart of the utility model embodiment.
In structure shown in the drawings, water level measuring cylinder (1) imports saturated vapor by vapour side tube connector (2) and water side tube connector (3) and drum (4) connection-core pipe (5) bottom of water level measuring cylinder, the upper end that the bottom of core pipe and dividing plate (6) become the heat-exchange surface core pipe between water and the saturated vapor flushes with vapour side tube connector, the condensate water that forms after the saturated vapor heat release that the core pipe imports flows in the down-comer (8) of drum by drain pipe (7), the discrepancy in elevation of this contact and water side tube connector is not less than 10m, because drain pipe is not incubated, mean temperature hydrophobic in the drain pipe is lower than saturation temperature, under the condition of the above-mentioned discrepancy in elevation, water level in the drain pipe can remain on below the water level measuring cylinder, heat exchange can be affected, this has just satisfied the condition of the utility model design thereby guarantee under any operating mode water temperature in the water level measuring cylinder to remain on saturation temperature, just can correctly show steam water-level under any operating mode.(9) are that electric contact (10) is a blow-off pipe in the accompanying drawing.When the utility model was used for station boiler, rated operating pressure was high more, can show its excellent structure property more more.
