Abstract
A large angle broad surface tubular two color tank gage displays two colors by using the principle that when the quartz glass cell is filled up with liquid and gas, the refractivity of light in liquid phase and gas phase are different. By enlarging the inner square hole side length of the quartz glass cell and broadening the viewing aperture of the body and the guard, the red and the green display surfaces of the quartz glass cell are broadened, and the viewing angles are enlarged too, which is very convenient for viewing the liquid level.
Description
The utility model is improved on the basis of quartz glass tubular type bi-colour water gauge, and its liquid level that is widely used in aspects such as oil, chemical industry is shown.
Quartz glass tubular type bi-colour water gauge, owing to be to show boiler steam bubble water level, pressure medium is big, and the temperature height requires quartzy tube wall thicker, and endoporus is less, and the square hole length of side has only 8mm, makes that the sightingpiston of gauge glass is narrower.Therefore, this gauge glass is not suitable for the liquid level demonstration of aspects such as oil, chemical industry.
The purpose of this utility model is according to aspect containers such as general oil, chemical industry, pressure is less, temperature is lower, characteristics such as viscosity is bigger have suitably reduced the wall thickness of quartz glass tube, have strengthened the size of endoporus, the sightingpiston and the angle of liquid level gauge are improved, simultaneously, can also make liquid level gauge under the situation of no electric light source, the brightness and the liquid level that increase natural light are observed sharpness.
Below in conjunction with Fig. 1, Fig. 2, illustrate how the purpose of this utility model realizes.
Fig. 1 is the general assembly drawing of the utility model wide-angle broad surface tubular liquid level gauge.This liquid level gauge mainly is made up of table body [1], last valve [2], lower valve [3], bi-color device [5], frequency modulated light plate [8], protective cover [7] and blowoff valve [4].Liquid enters quartz glass tube [6] by lower valve [3], gas by last valve [2], by the principle demonstration liquid level of linker.
Two red glass sheets [9] and a green glass sheet [10] are arranged above the bi-color device [5].Green glass sheet [10] is pieced together the centre that is clipped in two red glass sheets [9], and symmetry is placed on the back of quartz glass tube [6].The width of green glass sheet [10] is 12-24mm, and the width of red glass sheet [9] is 18-30mm.The external diameter of quartz glass tube [6] is a garden shape.Endoporus is shaped as square, and outside dimension is Φ 224-32mm.The interior square hole length of side is 11-16mm, thereby makes the width widen of the double-colored display surface of quartz glass tube.The length of green glass sheet [10], red glass sheet [9] and quartz glass tube [6] is determined by the observation length of liquid level gauge.Protective cover [7] places the front of table body [1], and the width of both viewports is 28-40mm, and viewing angle is 25 °-40 °, makes the viewing angle of liquid level gauge increase, and the length of viewport is determined according to customer requirements.
When available light or light-illuminating behind green glass sheet [10], green light sees through quartz glass tube [6] and is green at liquid phase, presents the wide green lines of about 1mm in vapour phase; Simultaneously, available light or light-illuminating be to red glass sheet [9], at liquid phase, red light in quartz glass tube [6], reflect make top view less than, then show redness in vapour phase.Because red display face and green display surface are widened, and the viewing angle increase, therefore very be convenient to observe liquid position.
Claims (3)
1, wide-angle broad surface tubular double colored indicator is that bi-color device [5], quartz glass tube [6], green glass sheet [10], red glass sheet [9] and protective cover [7] are formed by table body [1].It is characterized in that green glass sheet [10] assembly is clipped in the centre of two red glass sheets [9], and symmetry is placed on the back of quartz glass tube [6].Protective cover [7] places the front of table body [1], and the width of both viewports is 28-40mm, and viewing angle is 25 °-40 °, and the length of viewport is determined according to customer requirements.
2, wide double colored indicator of wide-angle according to claim 1, the width that it is characterized in that described green glass sheet [10] is 12-24mm, the width of red glass sheet [9] is 18-30mm, and the length of green glass sheet [10] and red glass sheet [9] is determined according to the observation length of liquid level gauge.
3, wide double colored indicator of wide-angle according to claim 1, the external diameter that it is characterized in that described quartz glass tube [6] is a garden shape, and endoporus is a square, and its specification is: outside dimension Φ 24-32, the interior square hole length of side 11-16mm, length is determined according to the observation length of liquid level gauge.
