Abstract
Disclosed is a dry-damp color change indicting sight glass, comprising a metal tube (3) and a liquid viewing glass (1) in sinter connection. Wherein the liquid viewing glass is arranged on the cross section of the metal tube (3), a screw thread (6) for connecting with other containers is arranged on the metal tube (3), a rivet (2) is in sinter connection with the center of the liquid viewing glass (1), a color change display paper (4) and a gasket (5) are fixedly arranged on the rivet (2) by stamping, and the color change paper (4) is arranged between the liquid viewing glass (1) and the gasket (5). The utility model not only has simple structure and good sealability, but also can display the humidity content of the liquid in a viewed container, particularly applicable to air-conditioning and refrigeration industries.
Description
Technical field
The utility model relates to the visor that industries such as a kind of air-conditioning, refrigeration are used, a kind of especially wet variable color indication visor, situation that is used to observe liquid in container done.
Background technology
The visor of industries observation liquid situations such as air-conditioning, refrigeration often adopts the metallic glass mirror of pin-connected panel at present, promptly with securing members such as bolts glass is cemented on the metal.This bind mode complex structure, it is many to consume material, and glass is easily broken during installation, and especially important disadvantages is that sealing is poor, and leakage phenomenon is serious during as liquid-sighting glass.Chinese patent CN2101853U discloses a kind of metal glass observation mirror, this sight glass adopts metal and glass sintering to form, though this structure has been avoided some shortcomings of assembly unit, still be difficult to determine the wet situation of doing of liquid in container by it, can't know and when should change liquid.
Summary of the invention
The purpose of this utility model provides a kind of wet variable color indication visor of doing, its not only simple in structure, good airproof performance, and can show the humidity content of observed liquid in container.
The technical scheme that realizes above-mentioned purpose is: a kind of variable color indication visor that wets of doing, comprise metal tube and vision-liquid glass that sintering connects, vision-liquid glass is positioned on the xsect of metal tube, have on the metal tube and be used for the screw thread that is connected with other container, vision-liquid glass center sintering is linked with rivet, be installed with variable color display paper and pad by punching press on the rivet, and the variable color display paper is between vision-liquid glass and pad.
After adopting technique scheme, metal tube and vision-liquid glass are coupled to one by sintering, simple, the good airproof performance of the visor structure compared that connects with pin-connected panel.Owing to rivet is arranged at vision-liquid glass center sintering, and on rivet, be fixed with variable color display paper and pad by punching press, can show the wet situation of doing in the container by the variable color display paper, the humidity in the container changes, and the color on the display paper also can be followed and be changed.People can determine the humidity content of liquid in container according to the color of display paper, thereby determine whether will change refrigerating fluid.
Description of drawings
Fig. 1 is first kind of structure cross-sectional schematic of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is second kind of structure cross-sectional schematic of the present utility model;
Fig. 4 is that the B of Fig. 3 is to view.
Embodiment
As shown in Figure 1, 2, a kind of variable color indication visor that wets of doing, comprise metal tube 3 and vision-liquid glass 1 that sintering connects, vision-liquid glass 1 is positioned on the xsect of metal tube 3, have on the metal tube 3 and be used for the screw thread 6 that is connected with other container, vision-liquid glass 1 center sintering is linked with rivet 2, is installed with variable color display paper 4 and pad 5 by punching press on the rivet 2, and variable color display paper 4 is between vision-liquid glass 1 and pad 5.
As shown in Figure 1, 2, the screw thread on the metal tube 36 is an external thread.
Shown in Fig. 3,4, be another kind of version of the present utility model, the screw thread 6 on the metal tube 3 is an internal thread.
It still is that internal thread can determine according to the actual installation needs that screw thread 6 on the metal tube 3 adopts external thread.
Shown in Fig. 1,2,3,4, be distributed with four through holes 7 on the pad 5, adopt through hole 7 to be convenient to the interior moisture of container and in time be penetrated on the variable color display paper 4, in time Show Color has increased the sensitivity of visor.
When the utility model uses, if variable color display paper 4 shows blueness then represents " doing "; Show the water grey, expression " warning " just reminds beginning in your container " to become tide "; Show pink, expression " wetting " just reminds you must change refrigerating fluid.Post the colour code signal on metal tube 3 surfaces of visor, can be user-friendly to.
The utility model is simple in structure, and cost is low, high temperature resistant, withstand voltage, good airproof performance, and the operator can understand the humidity content of internal tank refrigerant liquid and the mobility status of liquid by the utility model.
Claims (4)
1, a kind of variable color indication visor that wets of doing, comprise metal tube (3) and vision-liquid glass (1) that sintering connects, vision-liquid glass (1) is positioned on the xsect of metal tube (3), have on the metal tube (3) and be used for the screw thread (6) that is connected with other container, it is characterized in that: vision-liquid glass (1) center sintering is linked with rivet (2), rivet (2) is gone up and is installed with variable color display paper (4) and pad (5) by punching press, and variable color display paper (4) is positioned between vision-liquid glass (1) and the pad (5).
