Description
Technical Field
The utility model belongs to the technical field of the engine, concretely relates to high temperature pipeline viewing device.
Background
At present, due to the fact that dew point calibration and the like need to observe the water vapor evaporation condition of a sensor at a specific position of an exhaust pipe, the temperature of an engine tail gas pipe reaches 700 ℃ at most, and the engine tail gas pipe also contains different compounds, wherein pollutants comprise solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, water vapor, sulfur oxides and the like, and ultrahigh-temperature endoscope equipment is widely used in an observation pipeline.
The hot end endoscope has large volume and cannot be arranged in a compact space, and is not favorable for arrangement on a road test vehicle; the common endoscope can resist the temperature of 60 ℃ and the common high-temperature endoscope can resist the temperature of about 400 ℃, and the tail gas of the pipeline reaches 700 ℃, so that the requirement can be met only by the ultra-high-temperature endoscope; the tail gas is corrosive, so that the endoscope equipment is easily damaged; the water vapor is condensed in front of the lens, so that the observation is easy and unclear.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that exists among the prior art, the utility model provides a high temperature pipeline viewing device.
The utility model discloses a following technical scheme realizes:
a high-temperature pipeline observation device comprises an observation tube 1, a fixing screw nut 2, quartz glass 3 and a fixing flange 4, wherein a round hole is formed in the tube wall of the observation tube 1, the quartz glass 3 is matched with the round hole, the quartz glass 3 is fixed by the fixing screw nut 2 and the fixing flange 4, and a temperature sensor is arranged on the inner wall of the observation tube 1 opposite to the quartz glass 3; still be provided with a aperture on the observation tube 1, the aperture is used for passing the honeycomb duct, and the honeycomb duct is used for avoiding forming steam in the observation tube when low temperature, observation tube 1 is connected with the blast pipe of car through the flange.
Compared with the prior art, the utility model has the advantages as follows:
the high-temperature pipeline observation device of the utility model is installed and connected in series on the exhaust pipe, thereby saving the installation space; the observing tube, the fixed flange and the screw are made of metal materials which are resistant to high temperature, the quartz glass is resistant to the temperature of more than 1000 ℃, the device is resistant to the temperature of 1000 ℃, and the quartz glass and the pipeline metal are resistant to corrosion.

Fig. 1 is a schematic structural view of a high-temperature pipeline observation device of the present invention;
fig. 2 is a top view of a high temperature pipeline observation device of the present invention;
in the figure: observation tube 1, set screw nut 2, quartz glass 3, mounting flange 4.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1
A high-temperature pipeline observation device comprises an observation tube 1, a fixing screw nut 2, quartz glass 3 and a fixing flange 4, wherein a round hole is formed in the tube wall of the observation tube 1, the quartz glass 3 is matched with the round hole, the quartz glass 3 is fixed by the fixing screw nut 2 and the fixing flange 4, and a temperature sensor is arranged on the inner wall of the observation tube 1 opposite to the quartz glass 3; still be provided with a aperture on the observation tube 1, the aperture is used for passing the honeycomb duct, and the honeycomb duct is used for avoiding forming steam in the observation tube when low temperature, observation tube 1 is connected with the blast pipe of car through the flange.
In order to avoid the phenomenon that water vapor in the pipeline is attached to the quartz glass 2 to influence the observation at low temperature, a flow guide pipe of compressed air is arranged on the observation pipe 1, and the shape of the flow guide pipe is calculated through CFD fluid, so that the tail gas composition and the temperature at the observation position cannot be influenced. The observation pipe 1 is connected with the exhaust pipe through a flange, and when the engine runs, the running condition of the sensor is observed through the observation window.
