Abstract
The utility model belongs to the universal two colour level meter and mainly solves the problem that the universal float gage does not have a sound and light alarm device. The utility model is characterized in that a capacitive sensor is arranged in a float gage or a universal float gage and a sound and light alarm device is composed of a square wave generator circuit, a bridge type detecting circuit, a high water display circuit, a low water display circuit, a normal water display circuit, a super high water level alarm circuit, a super low water level alarm circuit. The utility model has the characteristic that the float can accurately reflect the states of water lacking or full water, and slight or serious water lacking or full water and also has the characteristics of electronically displaying high and low water level, displaying normal water level by two colors and water level alarming.
Description
The utility model relates to a kind of instrument element of monitoring liquid level, particularly a kind of universal two-color level meter that can be used for level monitorings such as boiler, pressure vessel and petrochemical complex.
China's utility model patent " float gauge " (90225326.3) and " omnipotent floating float gauge " (91225869.1) disclose a kind of float gauge that can be used for level monitorings such as boiler, pressure vessel and petrochemical complex, though can do accurately to show to lack of water, slight lack of water, serious water shortage, full water, slight full water, serious full water, electronics shows, warning device but be not provided with, do not possess the separate safety feature of two covers, thereby, do not meet the request for utilization of boiler equal pressure container.Sensing element metal tube (rod) in the electronic alarm device is because of contacting with high-temperature water or high-temperature steam for a long time, and its surface meeting fouling after the incrustation scale knot is full, just causes the malfunctioning of electronic alarm device.
The purpose of this utility model is exactly that a kind of that incrustation scale influences, as to have electronics demonstration, warning and float liquid level demonstration universal two-color level meter that is not subjected to is provided at above-mentioned weak point.
Technical solution of the present utility model is: a kind of universal two-color level meter, comprise float gauge or universal float-type fluviograph, it is characterized in that: in this float gauge or universal float-type fluviograph, be provided with a capacitive transducer, also comprise the square-wave generator circuit that links to each other with this capacitive transducer, the bridge-type detecting circuit, be subjected to the control of this detecting circuit by comparer, power door, the high water stage display circuit that charactron is formed, by comparer device power door, the low-water level display circuit that charactron is formed, by comparer, triode, the double-colored display circuit of ordinary water level that dichromatic LED is formed, and superelevation, the low-water level warning circuit.
The described capacitive transducer of the utility model technical solution can be to comprise the outer insulation course that is provided with of column type electrode and its, is arranged in the water, vapour chamber of float gauge or universal float-type fluviograph main body flat board.
Capacitive transducer described in the utility model technical solution can also be two parallel metal plate electrodes that comprise in the flute profile gland groove that is arranged on float gauge or universal float-type fluviograph, and this electrode is provided with insulation course outward.
The utility model is because at the water of the main body flat board of " float gauge " and " universal float-type fluviograph ", in the vapour chamber or the flute profile gland by water, be provided with capacitive transducer in the groove of vapour chamber one side, and the water level detecting circuit that cooperates with it, water level shows, warning circuit, both kept the float of float gauge or universal float-type fluviograph can accurately reflect scarce, full water, slight or serious lacking, the characteristics of full water, have electronics again and show the water level situation, the characteristics of water-level alarm, and, the pole plate of capacitive transducer (pipe) needs to use teflon insulation, thereby be not subjected to the influence of incrustation scale, eliminate incrustation scale at the bottom of the torr and caused electronics to show, the factor that warning device is malfunctioning.Metal plate type or column type capacitive transducer can design according to the body shape of water level gauge.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view (FV) of the utility model embodiment 1; And as Figure of abstract;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the front view (FV) of the utility model embodiment 2;
Fig. 4 is the sectional view of Fig. 3;
Fig. 5 is that electronics of the present utility model shows, warning circuit figure.
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment 2 is shown in Fig. 3,4, as different from Example 1: two parallel metal plate electrodes 6 are installed in the groove of float gauge or universal float-type fluviograph flute profile gland 5, are provided with polytetrafluorethylecoatings coatings 7 outside the sheet metal electrode 6, and this coating is an insulation course.Two metal sheets 6 is that medium forms electric capacity with the water of its outer insulation course 7 and its mezzanine space.
