Abstract
A kind of transmission bicolor liquid level indicator that is used for the liquid level demonstration is to be equipped with a reflector and an illuminator on the rear meter body of liquid level gauge, and each one of red, green colored filter is arranged on the front meter body of band peep-hole, and a gas-liquid pipe is arranged therebetween.This liquid level gauge is simple in structure, and the seal element of saved that prism is gentle, liquid, optical channel being used is made simple, convenient for installation and maintenance.This liquid level gauge simplifies its structure under the prerequisite that guarantees clear display greatly.
Description
The present invention relates to a kind of device that shows liquid level change.
No matter existing double colored indicator is reflective or reflective/transmissible, and its structure is all complicated.Generally there be at least one to play reflection or prism of transmission effect, the sight glass body that has groove, gas-liquid optical channel seal element or the like.
The objective of the invention is to provide a kind of clear display and structure foolproof again transmission bicolor liquid level indicator.
The object of the present invention is achieved like this: be equipped with a reflector and an illuminator on the rear meter body of liquid level gauge, each one of red, green colored filter is arranged on the front meter body of band viewport, a gas-liquid pipe is arranged therebetween.The present invention is in carrying out the liquid level procedure for displaying, when showing the gas part, the light that is sent by illuminator is mapped on red, the green optical filter after the reflector reflection, and light (can think that also light directly sees through optical filter, because optical filter is thinner) after the optical filter refraction, be mapped on the gas-liquid pipe, because the gas-liquid tube wall is thinner, the direct transmission of visible rays, at this moment, peep-hole visible red, green glow then are transmitted on the front meter body sidewall; When showing the liquid part.Because liquid and gas two medium difference in the gas-liquid pipe are bigger, the light that is mapped on the gas-liquid pipe reflects, at this moment, peep-hole is the green glow through reflecting as seen, and ruddiness is refracted on the sidewall of front meter body, and thus, what see in peep-hole is gas, liquid two parts that the clearly demarcated light of two kinds of colors shows.
The present invention has saved optical material and machining period owing to saved prism.Owing to adopt gas-liquid pipe as gas, liquid, optical channel, make simply and saved seal element.The liquid level gauge structure is simplified greatly, made simply, convenient for installation and maintenance, simultaneously, because main what utilize is the refraction principle of light, light path is simple and direct, clear display.That is to say that the present invention also makes its structure simplify greatly under the prerequisite that guarantees display effect.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the longitudinal sectional drawing according to the simple transmission type liquid level meter that the utility model proposes.
Fig. 2 is the transverse cross-sectional view of simple transmission type liquid level meter.Express the index path when showing the gas part among the figure.
Fig. 3 is the transverse cross-sectional view of simple transmission type liquid level meter.Express the index path when showing the liquid part among the figure.
(1) is for having the front meter body of peep-hole among the figure, peep-hole length is narrow at a distance nearby apart from illuminator, and peep-hole at Red lightscreening plate on one side, (2) be gas, liquid, the optical channel of gas-liquid pipe-promptly, (3) be Red lightscreening plate, (4) are reflector, and (5) are illuminator, (6) be rear meter body, (7) are green color filter
During this liquid level gauge work, be the part of gas in gas, liquid, the optical channel (2).As Fig. 2, the light that illuminator (5) sends is mapped on red, green optical filter (3), (7) after reflector (4) reflection, light is mapped on the gas-liquid pipe (2) after the optical filter refraction, the direct transmission of light, at this moment, peep-hole (1) visible red, green glow then is transmitted on the sidewall of front meter body (1).
In gas, liquid, the optical channel is the part of liquid, as Fig. 3.
The light that illuminator (5) sends is mapped on red, green optical filter (3), (7) after reflector (4) reflection, light is mapped on the gas-liquid pipe (2) after the optical filter refraction, and light reflects, at this moment, peep-hole (1) visible green, ruddiness then is refracted on the sidewall of front meter body (1).
Claims (2)
1, a kind of transmission bicolor liquid level indicator that is used for the liquid level demonstration, it is characterized in that: on the rear meter body of liquid level gauge, be equipped with a reflector and an illuminator, each one of red, green colored filter is arranged on the front meter body of band peep-hole, one gas-liquid pipe is arranged therebetween, peep-hole is on Red lightscreening plate one side, and peep-hole length is narrow at a distance nearby apart from illuminator.
2, transmission bicolor liquid level indicator according to claim 1 is characterized in that: 90 ° of Red lightscreening plate and green color filter angles.
