Description
Technical field
The utility model belongs to probe technologies field, and in particular to a kind of probe apparatus.
Background technology
Following major defect be present in the PRO2001WHP-BG dilution probes used at present：(1) module is diluted using sealing
Circle is connected with thief rod, is caused gas leakage after sealing ring aging or sealing ring breakage, is influenceed normally to measure；(2) module sound is diluted
The rate of air sucked in required for ringing aperture is only 50-100ml/m3, it is 2 minutes or so to exhaust flue gas required time in feeler lever completely, causes to measure
As a result serious hysteresis；Similarly, after carrying out whole demarcation to instrument using calibrating gas, it is slower to recover normal measurement；(3) it is former dilute
The blowback relay working voltage used of popping one's head in is released as 3-24VDC, is easily interfered and produces malfunction, causes to upload environmental protection
Data exception；(4) for former dilution probe under the operating mode in face of complexity, antijamming capability is poor.
Utility model content
The purpose of this utility model is to provide a kind of probe apparatus, so as to can be efficiently against above-mentioned deficiency.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of probe apparatus, including tetrafluoro material sleeve, tetrafluoro material cartridge exterior are provided with heating insulation layer；Tetrafluoro material
Cartoon three-way connection is connected with the right side of sleeve；Flue gas delivery pipe is connected with the right side of cartoon three-way connection；Cartoon three-way connection bottom
It is connected with pneumatic air extractor；The needle-valve of scale regulation is provided with the left of pneumatic air extractor on pipeline；Cartoon three-way connection
With being provided with heatproof Tetrafluoro spacer and sealing ring at tetrafluoro material sleeve connection；Tetrafluoro material sleeve top position is provided with Venturi tube
Base；Velocity of sound aperture base is provided with Venturi tube base；Velocity of sound aperture is installed in velocity of sound aperture base；Venturi tube base
Centre position is provided with Venturi tube；Venturi tube base top is provided with fastening steel disc, and fastening steel disc top is using fastening spiral shell
Silk is installed fixation.
In the device, velocity of sound aperture is used to produce constant current, produces constant dilution ratio；Using heatproof Tetrafluoro spacer,
On the basis of originally being sealed using sealing ring, Seal Design is added, it is ensured that be not in leakage problem；Sealing ring is used to prevent
Only dilute module and realize sealing with feeler lever junction.
The utility model device has the advantages that：The device major advantage is as follows：(1) leakage of module junction is diluted
Gas problem is resolved；(2) measurement result has obtained quick response, solve because rate of air sucked in required is small and caused by measurement result it is stagnant
Problem afterwards；(3) blowback relay is not present and is disturbed caused malfunction；(4) under the operating mode in face of complexity, antijamming capability
It is remarkably reinforced.
