Embodiment 1

[0018] See figure 1 and 2 , a hollow glass dew point meter, comprising an L-shaped measuring tube 1 with openings at both ends, a cooling tank 2 and a temperature sensing device 3 plugged in at one end of the measuring tube 1, the cooling tank 2 and the measuring tube 1 are connected to form a container for holding In the accommodating space of the refrigerant liquid 4, the probe 3a of the temperature sensing device 3 extends into the refrigerant liquid 4, and the outer surface of the bottom of the refrigeration tank 2 forms a condensation mirror 2a, which is perpendicular to the liquid surface of the refrigerant liquid 4. Among them, the measuring tube 1 can also be set to other forms with a certain bending angle, which can be made of quartz glass. The measuring tube 1 made of quartz glass is resistant to low temperature, easy to clean, and high in definition. When observing, the window of the measuring tube 1 is good to reduce the measurement error, and it can also be made ...

Embodiment 2

[0021] See image 3 and 4 Compared with Embodiment 1, the difference of this embodiment is that a hollow glass dew point meter includes a straight measuring tube 1 with openings at both ends, a cooling tank 2 and a temperature sensing device 3 plugged in at one end of the measuring tube 1, and the cooling tank 2 is connected with the measuring tube 1 to form an accommodating space for containing the refrigerant liquid 4. The probe 3a of the temperature sensing device 3 extends into the refrigerant liquid 4. The refrigeration tank 2 includes multiple planes, one of which is a condensation mirror 2a, and the condensation mirror 2a is perpendicular to the liquid surface of the refrigerant liquid 4 . The cooling tank 2 can be set in an L shape, and its side protrudes to form a condensation mirror 2a, and the bottom of the cooling tank 2 can also be set as a condensation mirror 2b, so that the cooling tank 2 has two detection surfaces, which can be erected on the glass The dew po...

Abstract

The invention relates to the technical field of hollow glass detection, in particular to a hollow glass dew-point instrument. The hollow glass dew-point instrument comprises a measuring tube with two openings in two ends, a temperature sensing device and a refrigeration slot in plug-in connection with one end of the measuring tube, wherein an accommodating space for holding refrigeration liquid is formed by the connection of the refrigeration slot and the measuring tube; a probe of the temperature sensing device stretches into the refrigeration liquid; the refrigeration slot comprises at least one condensation mirror plane perpendicular to the liquid level of the refrigeration liquid. Compared with the prior art, the instrument has the advantage that during a dew point test of oversized or super-thick hollow glass, the operation can be completed only by leaning the condensation mirror plane of the dew-point instrument against the glass, without horizontally placing the glass, so that time, space and manpower for horizontally placing the glass are saved, and direct dew point testing of hollow glass on a glass curtain wall can be realized.

Description

technical field [0001] The invention relates to the technical field of detection of hollow glass, in particular to a dew point meter for hollow glass. Background technique [0002] The traditional hollow glass dew point meter consists of a straight cylindrical measuring tube with openings at both ends, a cooling tank and a temperature sensing device inserted at one end of the measuring tube. The bottom of the cooling tank is a condensing mirror. Add refrigerating liquid into the refrigerating tank to cool it down to minus 40°C. The refrigerating tank cools the part attached to it through the condensing mirror. The temperature of the liquid is the dew point, and the dew point of the insulating glass is determined by the temperature sensing device. When performing dew point test on insulating glass, it is necessary to lay the insulating glass flat for measurement, which leads to a waste of space for placing the glass flat and requiring many It is a waste of manpower and easy...
