Description
Technical field
The utility model relates to a kind of checkout equipment, relates in particular to a kind of compressed natural gas water dew point and detects special-purpose refrigeration camera lens.
Background technology
Compressed natural gas (CNG) belongs to clean energy resource, and for the needs of energy-saving and emission-reduction, protection of the environment, country advocates exploitation, promotes and use the CNG automobile energetically.In the quality testing of CNG makings, moisture and sulfur content are national quality technical supervision department compulsory test index subjets.
Traditional detection method is that electrolytic process water content detection and dew point transmitter detect, the electrolytic process water content detection in actual use, there is again its singularity in the CNG gas station, rock gas is in compression process, can be mixed into a large amount of gaseous state lubricating oil, though still contain after filtration part gaseous state lubricating oil.Lubricating oil can progressively cover on the phosphorus pentoxide coating, makes phosphorus pentoxide coating and to be detected gas-insulated, pollutes, and later maintenance cost is high.Dew point transmitter can be by testing the resistance between two plate electrodes, the moisture that capacitance difference correspondence in different in moisture content in gas calculates rock gas, and electronic circuit is in service for a long time, electron device inevitably can decay, aging, therefore long-time usage data has drift, needs periodic calibration.
The utility model content
The purpose of this utility model detects special-purpose refrigeration camera lens with regard to the compressed natural gas water dew point that is to provide a kind of simple in structure, for convenience detach in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises leads warm bar, a described end of leading warm bar is the detection minute surface that polishes smooth, the other end is for connecting the cold junction face of refrigeration plant, be provided with Gold plated Layer on described detection minute surface, the described close side that detects minute surface of warm bar of leading is provided with the screw thread that is tightly connected, and a described side of leading the close cold junction face of warm bar is provided with and is fixedly connected with screw thread.
Particularly, the periphery of described detection minute surface is provided with groove, is provided with sealing O type ring in described groove.
Further, described detection minute surface is diameter 6-15 millimeter.
The most preferential, the diameter of described detection minute surface is 8 millimeters.
Particularly, describedly lead warm bar for leading warm copper bar.
Further, described sealing O type ring is sealing O type rubber ring.
The beneficial effects of the utility model are:
The utility model can adopt the global design integral material to adopt copper, leads temp effect good, detects minute surface and adopts gold-plated processing, effectively prevents equipment corrosion, and is simple in structure the serviceable life of extension device, is easy to install, and is convenient to cleaning.
Description of drawings
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is diagrammatic cross-section of the present utility model.
In figure: 1-cold junction face, 2-is fixedly connected with screw thread, and 3-leads warm bar, the 4-screw thread that is tightly connected, the 5-groove, 6-sealing O type ring, 7-detects minute surface, 8-Gold plated Layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As illustrated in fig. 1 and 2, the utility model comprises leads warm bar 3, a described end of leading warm bar 3 is the detection minute surface 7 that polishes smooth, the other end is for connecting the cold junction face 1 of refrigeration plant, detect on minute surface 7 and be provided with Gold plated Layer 8, lead warm bar 3 and be provided with near a side that detects minute surface 7 screw thread 4 that is tightly connected, a side of leading warm bar 3 close cold junction faces 1 is provided with and is fixedly connected with screw thread 2.
As shown in Figure 1, the periphery of detecting minute surface 7 is provided with groove 5, is provided with sealing O type ring 6 in groove 5, detecting minute surface 7 is diameter 6-15 millimeter, and in the present embodiment, the diameter that detects minute surface 7 is 8 millimeters, lead warm bar 3 for leading warm copper bar, sealing O type ring 6 is sealing O type rubber ring.
Detection principle of the present utility model is: will detect minute surface 7 and be cooled to uniform temperature, in gas, contained humidity is when detecting minute surface 7 generation condensation, and this temperature is the water dew point value of this gas.In practical operation, detect the cooling of minute surface 7 and adopt the methods such as liquid nitrogen, carbon dioxide decompression gasification, propane decompression gasification, operating personnel determine whether the generation condensation by observing minute surface, determine dew point value.
As shown in Figure 1, workflow of the present utility model is as follows: an end of leading warm bar 3 is connected with refrigerator by being fixedly connected with screw thread 2, after the other end of leading warm bar 3 is connected refrigerator with testee and starts working by the screw thread 4 that is tightly connected, make 1 cooling of cold junction face, by leading warm bar 3, the temperature that detects minute surface 6 is reduced, detect minute surface 6 contact compressed natural gass, sealing O type rubber ring 5 separates compressed natural gas with the part that does not need to contact compressed natural gas.
