Description
Technical field
It the utility model is related to a kind of sampler, and in particular to a kind of portable No leakage micro-positive pressure pipeline sampling dress
Put, belong to the dustiness detection sampling equipment technical field after gas purification.
Background technology
Gas dust content is related to environmental protection or subsequent user gas safety, such as：Various exhaust gas dustiness discharge beyond standards will
Seriously affect environment；Gaseous fuel dustiness is exceeded will to cause subsequent user preheater, burner to block.How gas is monitored in real time
Dustiness situation, current many manufacturers have had been equipped with automatic on-line detection dustiness equipment, but since application environment is different,
Often there is fluctuation situation in online detection instrument measured value, is that dustiness is exceeded or equipment fault, in many cases without
Method judges, calibration had no alternative but to be measured by manual sampling.Sampled on this micro-positive pressure gas pipeline, it is necessary to avoid
Gas leaks during sampling, also to prevent that particulate matter settles in sampling process gas, while also to prevent gas pipeline inner wall dust stratification
Influence, sampler species of the prior art is various, but mostly there is the technical problems such as leakage, therefore, urgent need
A kind of new scheme solves the technical problem.
The content of the invention
The utility model is exactly to be directed to technical problem existing in the prior art, there is provided a kind of portable No leakage micro-positive pressure
Pipeline sampler, the technical solution is compact-sized, convenient for disassembly and assembly, safe and reliable, ensures that each sealing station is good, Jin Ershi
Existing No leakage, scientific sampling design.
To achieve these goals, the technical solution of the utility model is as follows, a kind of portable No leakage micro-positive pressure pipeline
Sampler, it is characterised in that the sampler includes probe tube, sampling gun, gas conduit and collection device, described to take
One end connection probe tube of sample rifle, other end connection gas conduit, the bottom connection collection device of the gas conduit.The program
It is compact-sized ingenious, copper sealing sliding block is devised in the program, self sealss are carried out by micro-positive pressure in gas pipeline.
One kind as the utility model is improved, and the sampling gun includes sampling gun body and is arranged on sampling gun body
On self sealss sliding block, sealing nut, flow control valve and guide coupling, the guide coupling is arranged on sampling gun sheet
The end of body is used to connect gas conduit.
One kind as the utility model is improved, and the sealing nut is arranged to the sealing nut with chamfered bore.
One kind as the utility model is improved, and the probe tube includes sampling tube body and is arranged on sampling tube body
Upper ball valve.
The mounting ball valve on the horizontal level setting probe tube of gas pipeline, probe tube, in ball valve outer end, installation carries two
The metal tube of captacula tooth；Sampling gun front end sets section, and direction is vertical with airflow direction, and copper sealing is set among sampling gun
Sliding block and the slidably band copper sealing nut of chamfered bore, set flow control valve behind sampling gun, easy to control gas flow rate, after
Portion connects collection device.
Relative to the prior art, the utility model has the following advantages that, 1）It is the technical solution compact overall structure, ingenious,
It is convenient for disassembly and assembly, safe and reliable, ensure that each sealing station is good, and then realize No leakage, scientific sampling design；2）The technical side
Case cost is relatively low, easy for installation, easy to promote and apply on a large scale.

Embodiment：
In order to deepen the understanding to the utility model, the present embodiment is described in detail below in conjunction with the accompanying drawings.
Embodiment 1：Referring to Fig. 1-Fig. 4, a kind of portable No leakage micro-positive pressure pipeline sampler, the sampler bag
Probe tube 2, sampling gun 3, gas conduit 4 and collection device 5, one end connection probe tube of the sampling gun are included, the other end connects
Connect gas conduit, the bottom connection collection device of the gas conduit.The program is compact-sized ingenious, and copper is devised in the program
Matter seals sliding block, carries out self sealss by micro-positive pressure in gas pipeline, the sampling gun includes sampling gun body 12 and sets
Self sealss sliding block 6, sealing nut 7, flow control valve 8 and guide coupling 9 on sampling gun body, the conduit connection
The end that device is arranged on sampling gun body is used to connect gas conduit, and the sealing nut is arranged to the sealing spiral shell with chamfered bore
Cap.The probe tube 2 includes sampling tube body 10 and is arranged on sampling tube body upper ball valve 11.In the horizontal position of gas pipeline
Install probe tube, mounting ball valve on probe tube, in metal tube of the ball valve outer end installation with two captacula teeth；Sampling gun front end is set
Section is put, direction is vertical with airflow direction, sets copper sealing sliding block and slidably band chamfered bore copper close among sampling gun
Nut is sealed, flow control valve is set behind sampling gun, easy to control gas flow rate, rear portion connection collection device.
Operation principle：Referring to Fig. 1-Fig. 4, a kind of portable No leakage micro-positive pressure pipeline sampler, needs before implementation process
To needing gas sampled pipeline 1 to carry out perforate and be welded on probe tube 2 to need on 1 horizontal level of gas sampled pipeline, sampling is closed
Ball valve 11 on pipeline.
1）Plug in rifle process
The flow control valve 8 on sampling gun is closed, sampling gun 3, is inserted into probe tube by moving parts 6,7 to sampling gun front end
To 11 position of ball valve, band chamfered bore sealing nut 7 is tightened on probe tube 2, opens ball valve 11, further rifle is inserted into straight
Preceding section to sampling gun 3 plugs in rifle process from 1 inner wall a certain distance of gas pipeline, completion.
2）Sampling process
Connection gas conduit 4 and collection device 5 open flow control valve 8, collection device are carried out to take gas to air gun 3 is taken,
Flow control valve 8, which is closed, after taking gas completes sampling process.During if necessary to carry out dustiness detection to gas, solid gaseous mixture,
Only collection device need to be changed to filtration apparatus adds flowermeter, and can calculate gas with gas volume by solid masses contains
Dust quantity.
3）Unpile arms process
After completing sampling operation, gas conduit 4 and collection device 5 are removed, sampling gun 3 is slightly promoted, then slowly exits and take
Sample rifle 3 closes ball valve 3, back-outs band chamfered bore sealing nut 7, take out sampling gun 3, complete to unpile arms to 11 outer end of probe tube ball valve
