Abstract
The utility model flue gas field of measuring technique, specially a kind of smoke sampling pipeline structure, it can easily realize that deashing operates, ensure measurement result, it includes pressure transmitter, and the pressure transmitter connects anti-blocking sampler by sampling line and a valve, it is characterised in that, the sampling line is made of at least two connecting tubes and straight coupling, and the straight coupling includes the junction block of two threaded connections.
Description
Technical field
The utility model flue gas field of measuring technique, specially a kind of smoke sampling pipeline structure.
Background technology
In pulverized-coal fired boiler, since dust content is larger in boiler furnace and flue, in flue gas pressures flow probe tube
Certain dust stratification can be had by accumulating over a long period in road, and sampling line is generally all longer, deashing operating difficulties, the presence meeting of dust stratification
Influence measurement effect.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of smoke sampling pipeline structure, can be easily real
Existing deashing operation, ensures measurement result.
Its technical solution is such：A kind of smoke sampling pipeline structure comprising pressure transmitter, the pressure inverting
Device connects anti-blocking sampler by sampling line and a valve, which is characterized in that the sampling line is by least two connecting tubes
It is constituted with straight coupling, the straight coupling includes the junction block of two threaded connections.
It is further characterized by the junction block one end is light bar segment, the other end is installed with internal thread hole, separately
One described junction block one end is light bar segment, the other end is provided with the external screw thread coordinated with the internal thread hole, the connecting tube
It is set in the light bar segment of the junction block.
After the utility model, when dust stratification is more in sampling line, can by sampling line be segmented dismounting check into
The processing of row deashing, ensure that measurement result.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is straight coupling structural schematic diagram.
Specific implementation mode
See Fig. 1, shown in Fig. 2, a kind of smoke sampling pipeline structure comprising pressure transmitter 1, pressure transmitter 1 pass through
Sampling line 2 and a valve 3 connect anti-blocking sampler 4, and sampling line 2 is made of multiple connecting tubes 5 and three straight couplings 6,
Straight coupling 6 includes junction block 6-1,6-2 of two threaded connections, and the one end junction block 6-1 is light bar segment, the other end opens up
It is equipped with internal thread hole, the one end another junction block 6-2 is light bar segment, the other end is provided with the external screw thread coordinated with internal thread hole,
Connecting tube 5 is set in the light bar segment of junction block 6-1 and junction block 6-2.It when disassembly is desired, can be with by dismantling straight coupling
Two intermediate connecting tubes 5 are removed and carry out deashing processing, other two fixed connecting tube 5 can also easily realize deashing
Processing.7 be flue or burner hearth in figure.
