Embodiment
Below in conjunction with drawings and the specific embodiments the present invention is described in detail.
To contract than 3: 1 liquid level gauge measuring liquid level of range height is that the example of 3m is embodiment, specify as follows: the profile plate 1 of employing, its width (X-direction) is 116mm, thickness (y direction of principal axis) is 49mm, length (short transverse) is 1650mm, cover plate 5 is installed in the square inserting slot of the horizontal connecting plate 1-3 of profile plate, its width is 50mm, thickness is 3mm, in the slot of horizontal connecting plate, the graduated scale that each installs a width is 40mm, the graduated scale precision is 1mm, the range of graduated scale is 3m, in a part by the straight plate section of profile plate, in in the inner chamber that web joint and back shroud surrounded, install counterweight pulley, the length of counterweight pulley and width and thickness are 150 * 30 * 26mm, the diameter of the stainless steel wire rope of used traction is φ 2mm, in profile plate, respectively be the 40mm place every the two ends up and down of web joint, in on web joint, offer hole, in this hole, be installed as the power wheel of φ 25 * 35mm, the fluorescence colour band is 0.03mm by thickness, width is the stainless steel band of 35mm and the fluorescent film formation that is 3200mm in its surperficial bonding length, fluorescent film is divided into red, white two kinds of colors, this fluorescence colour band is walked around two power wheels, its two ends are connected with the counterweight pulley end, and the fluorescence colour band just becomes a ring body like this, fluorescence colour band red, white separatrix overlaps with graduated scale reading " zero " position.The bonnet width of profile plate is 75mm, thickness is 22mm, thickness of slab is 1.2mm, it is set in the square inserting slot of inclination web joint 1-1 of profile plate, the installation card that is used to place this liquid level gauge by horizontal connecting plate 1-3 and their groove that the outer constituted of inclination web joint 1-1, a travelling block is installed in upper end at counterweight pulley, the diameter of travelling block is 20mm, this travelling block horizontal level is set a wire rope stationary shaft 10mm with it, a fixed pulley is installed on top at profile plate, and the diameter of fixed pulley is 20mm, and the termination of wire rope is fixed on the stationary shaft of wire rope, upwards walk around fixed pulley, and then walk around travelling block upwards.
The contracting ratio range high definition fluorescent chromatape liquid-level meter that adopts said structure with the process that contracts at 3: 1 than range test fluid position is: when liquid level in the tank body is in zero, float in jar is in pot bottom, counterweight pulley in the liquid level gauge is in the upper end position of liquid level gauge at this moment, red, the white separatrix that is colour band is on " zero " location of reading of graduated scale, the indicated value of liquid level is zero, liquid level slowly begins to raise in tank body, and then float also slowly raises, and counterweight pulley then slowly glides.Because configuration travelling block mechanism in the liquid level gauge, when 3 parasangs of the every rising of float, colour band is red, white separatrix indicates 1 parasang that then rises, when float liquid level in jar reaches 3 meters, colour band is red, white separatrix sign reaches 3 meters of liquid level gauge the Highest Directives value, but it is red, the actual stroke of having finished 1 meter in white separatrix, otherwise float descends when liquid level is slowly landed, counterweight pulley rises, colour band is red, white separatrix sign descends, so just formed float measurement, the colour band display synchronization is carried out, and is hot, when white separatrix sign overlaps with a certain scale value of graduated scale, just can indicate the true liquid level in the fluid reservoir.So far, this liquid level gauge has just been finished the overall process of level gauging, demonstration.
