Description
Technical field
It the utility model is related to gas detection technology field, more particularly to automobile emission gas analyzer technical field.
Background technology
Increasingly improved with the attention rate of public's environmental pollution, State Bureau of Environmental Protection also increases the factor to influenceing environment
The dynamics that legislation is administered.Wherein just include the improvement requirement to the exhaust emissions of automobile.Each engine production factory, automobile factory, inspection
Survey the development and research that mechanism also adds input to carry out low emission level engine.But existing discharge detection device is deposited in configuration aspects
In defect, analyzer demarcation pipeline is all directly to draw marked gas from calibrating cylinder, is directly connected to analyzer test gas
Arrival end, by solenoid valve control, analyzer selection demarcation or test, this structure is set to check that analyzer is in itself
It is no problematic, but the problem of can not detect between sampling probe to analyzer, particularly leakage problem, and leakage problem exists
It is recurrent in actually detected, when sample lines to any one joint, pipeline, valve etc. between analyzer have leakage part
Analyzer will be caused to the measurement result to make mistake.
Utility model content
In order to solve above mentioned problem present in existing gas detection, the utility model provides a kind of gas analyzer and surveyed
Try check device.
Used technical scheme is the utility model to achieve the above object：Gas analyzer test-based examination device, mark
Determine the gas joint 10 that gas cylinder 14 connects voltage stabilizing casing 13 by gas pipeline 9, be located in voltage stabilizing casing 13 under gas joint 10
Portion's connection gas probe 12, gas pipeline 9 is provided with pressure-regulating valve 8, and the demarcation pipeline 9 in the exit of calibrating cylinder 14 is provided with
Pressure-reducing valve 11；Floating ball flow indicator 6 is installed on the top of voltage stabilizing casing 13, and floating ball flow indicator 6 is connected by gas exhaust piping 2 and arranged
Put gathering tube 1；The gas analyzer 4 of voltage stabilizing casing 13 connects the sampling joint 16 of voltage stabilizing casing 13 by analyzer sampling pipe 5, surely
Press in casing 13 positioned at the bottom of sampling joint 16 connection sampling probe 3.
The gas joint 10 and sampling joint 16 are provided with quick-release connector 7.
Gas analyzer test-based examination device of the present utility model, can be with by the way that marked gas is introduced directly into sampling pipe
There is any problem, or sampling with the presence or absence of problem either analyzer in the quick whole system for judging emission test equipment
Any one link such as probe, sampling pipe is problematic to be can be transferred through comparing measured value and actual value is directly found.Avoid because of pipe
Road, valve etc., which go wrong, causes the measurement of mistake, ensures measurement accuracy.

Embodiment
Gas analyzer test-based examination apparatus structure of the present utility model is as shown in figure 1, calibrating cylinder 14 passes through gas pipe
Road 9 connects the gas joint 10 of voltage stabilizing casing 13, and the bottom of gas joint 10 connection gas probe 12, mark are located in voltage stabilizing casing 13
Air pipe 9 is provided with pressure-regulating valve 8, and the demarcation pipeline 9 in the exit of calibrating cylinder 14 is provided with pressure-reducing valve 11；Voltage stabilizing casing 13
Floating ball flow indicator 6 is installed on top, and floating ball flow indicator 6 connects discharge gathering tube 1 by gas exhaust piping 2；Voltage stabilizing casing
13 gas analyzers 4 connect the sampling joint 16 of voltage stabilizing casing 13 by analyzer sampling pipe 5, are located at sampling in voltage stabilizing casing 13
The bottom of joint 16 connects sampling probe 3, and gas joint 10 and sampling joint 16 are provided with quick-release connector 7.
Concrete operation step is as follows：The pressure loading valve 11 of calibrating cylinder 14 is opened, marked gas passes through pressure-reducing valve 11, gas
Pipeline 9 and gas probe 12 enter 13 in present apparatus pressurizer tank, by adjusting the pressure-regulating valve 8 of the present apparatus in gas point
Analyzer 4 sample when floating ball flow indicator 6 have a little gas overflowing present apparatus, with ensure analyzer sampling when sampling pipe pressure
Meet equipment requirement, the sampling probe 3 of analyzer the interior collection gas out of voltage stabilizing casing 13, leads to being placed in voltage stabilizing casing 13
Cross analyzer sampling pipe 5 and carry out the progress analysis measurement of gas analyzer 4, and unnecessary a small amount of marked gas is referred to by ball float flow
Show that device 6 and gas exhaust piping 2 enter the discharge gathering tube 1 of equipment, the nominal value of the measured value of analyzer and demarcation gas is compared
Compared with can directly judge that measuring system whether there is problem.Marked gas can be made to enter analyzer from sample lines, rather than
Avoid sample lines.
