Abstract
The utility model discloses a liquid viewing glass which comprises a shell body, and a bracket and an eyeglass that are arranged on the middle part of the shell body; a bimetallic thermometer is arranged surrounding the bracket in the shell body; one end of the bimetallic thermometer is provided with a pointer. The thermometer which can measure the temperature of a cool medium is designed in the liquid viewing glass, and the material of the thermometer is metal with indicated temperature from-40 DEG C to +500 DEG C, so that a new function is added to the liquid viewing glass with the cool medium, with reasonable structure and convenient operation.
Description
Technical Field
The utility model relates to a liquid mirroris looked to refrigerant that is used for the water condition in the observation system pipeline in the refrigeration plant, especially a can instruct medium temperature.
Background
An important parameter in the use of the liquid viewing mirror is the temperature of a medium, and the currently used refrigerant liquid viewing mirror, whether imported or made in China, is not provided with a thermometer, so that a user cannot master the temperature of the medium, inconvenience is brought to the use of the user, and the use efficiency of the liquid viewing mirror is greatly reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a use more convenient, can survey sight glass of cold medium matter temperature.
The purpose of the utility model is realized like this:
a liquid viewing mirror comprises a shell, a bracket and a lens, wherein the bracket and the lens are positioned in the middle of the shell, a bimetal thermometer is arranged in the shell around the bracket, and one end of the bimetal thermometer is provided with a pointer.
The utility model discloses designed the thermometer in looking the liquid mirror, the material of this kind of thermometer is the metal moreover, and the instruction temperature can be followed-40- +500 ℃, for the refrigerant looks the liquid mirror and has increased new function, rational in infrastructure, convenient to use.

FIG. 2 is a sectional view taken along line A-A of FIG. 1
Detailed Description
The utility model discloses a look liquid mirror, including casing 2, a support 5 is established at 2 middle parts of casing, centers on support 5 welding bimetal thermometer 4, and a pointer 3 is established to bimetal thermometer 4's one end, indicates the temperature of flowing through liquid. A humidity indication color changing sheet 7 is terminated on the upper end of the bracket 5. The outer layer of the shell 2 is provided with a lens 8.
The humidity indication color-changing agent of the utility model adopts a self-developed formula:
after repeated tests, the reaction is sensitive, and the reaction does not have chemical combination reaction with cold medium, and the liquid crystal display is arranged in a liquid lens, can detect one ten-thousandth of water, and has the service life of three years.
The utility model discloses a look liquid mirror dress in leading to liquid pipe 1, when the medium flows through or has moisture content to produce, look the calibrated scale on the liquid mirror face and just have corresponding parameter display. The humidity indicator color changing sheet 7 is blue in the absence of moisture and pink in the presence of moisture, and may be made green in the absence of moisture and yellow in the presence of moisture.
