Technical field
The utility model relates to a kind of water level gauge that is used to measure boiler water level, specifically relates to a kind of differential pressure electrode integral type water level meter that is used to measure boiler water level.
Background technology
Electrode type fluviograph is by measuring tube and the secondary table is supporting forms, and an electrode installation site of measuring tin is corresponding with the light emitting diode on the secondary table, and the secondary table shows water position status in the pulpit, and carries out sound and light alarm and chain control when water level abnormality.This instrument is widely used on the water receptacle of various different pressures such as boiler-steam dome, water tank, temperature.
Differential pressure water level gauge is made up of equalizing reservoir and differential pressure transmitter two parts, the level monitoring such as boiler-steam dome, storage tank, storage tank that is widely used in industries such as power plant, chemical plant, metallurgy, compare with other water level gauge, it is wide to have suitable pressure limit, the operation leakage point is few, the reliability height shows that water level is accurate, characteristics such as remote central station of floating dock supervision.
Differential pressure water level gauge is to adopt differential pressure principle, measures the differential pressure value of the static pressure (following water-level lifting and change) of actual water level in static pressure in the equalizing reservoir and the container.By differential pressure transmitter differential pressure value being transformed into current signal is transferred to and carries out level monitoring on the central station of floating dock computing machine.This instrument adopts pressure transmitter measurement pressure that saturation water, vapour density in the drum are compensated.
The principle of work of electric contact point fluviograph is to utilize the characteristic of the electric conductivity difference of stove water and steam to carry out measuring liquid level.Because the variation of liquid level is immersed in the water partial electrode, partial electrode places steam, electrode pair cylindrical shell impedance in stove water is little, and the impedance of the electrode pair cylindrical shell in steam is big, utilize this characteristic, the water level of non electrical quantity can be converted into electric weight, give secondary instrument, thereby realize functions such as the demonstration of water level, the output of reporting to the police.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can realize boiler water level differential pressure measurement and electrode measurement and the differential pressure electrode integral type water level meter with low cost of manufacture simultaneously.
For solving the problems of the technologies described above, the utility model differential pressure electrode integral type water level meter comprises measures tube and differential pressure transmitter, described the same side of measuring tube is respectively equipped with vapour side stopple coupon and lateral water sampling tube, measure the tube inherence and be provided with equalizing reservoir along this measurement tube central axial direction, this equalizing reservoir lower end is connected with the positive pilot connecting leg of equalizing reservoir, also be provided with the negative pilot connecting leg of equalizing reservoir on this measurement tube barrel, described differential pressure transmitter links to each other with the negative pilot connecting leg of positive pilot connecting leg of described equalizing reservoir and equalizing reservoir respectively by three valve groups, also be provided with electrode on the vapour side stopple coupon of measuring tube and the barrel between the lateral water sampling tube, this electrode links to each other with the secondary instrument that is used for the non electrical quantity water level is converted into the electric weight water level.
The differential pressure electrode integral type water level meter of employing said structure has been realized the combination of differential pressure water level gauge and electric contact type water level gauge, measures tube by shared one and has reduced manufacturing cost.In addition because the thief hole of traditional old-fashioned boiler-steam dome design is few, water level gauge is installed when measuring water level quantitatively has been subjected to restriction to a certain degree, often electric contact point fluviograph and differential pressure water level gauge can not be installed simultaneously, adopt water level gauge of the present utility model because thereby a shared measurement tube has been saved the drum thief hole, be fit to the drum level measurement of traditional old-fashioned boiler more.
