Abstract
The utility model discloses a kind of gas sampling gun provided with combined moving static pressure Pitot tube, including the waste gas sampling pipe and dynamic and static pressure Pitot tube on handle, the front end of the waste gas sampling pipe connects sampling mouth through Particulate Filter, the dynamic and static pressure Pitot tube is made up of the back segment and leading portion being connected by detachable attachment mechanism, and the back segment is arranged on handle.When the leading portion of dynamic and static pressure Pitot tube is by collision deformation, the new leading portion changed and crossed in advance through Pitot tube factor check is pulled down, effectively reduces use cost, and need to only carry the several leading portions crossed in advance through Pitot tube factor check, it is easy to carry.
Description
Technical field
It the utility model is related to gas sampling gun field, and in particular to a kind of flue gas provided with combined moving static pressure Pitot tube
Sampling gun.
Background technology
Gas sampling gun is to used sample devices during waste gas monitoring, and its structure includes being arranged on handle
Waste gas sampling pipe and dynamic and static pressure Pitot tube, the front end of the waste gas sampling pipe connect sampling mouth through Particulate Filter；It is wherein dynamic
Static pressure Pitot tube is to measure dynamic pressure and static pressure in flue simultaneously, once the front end of dynamic and static pressure Pitot tube deforms, will be caused
Error of measured data is larger, but measure field is ill-conditioned, and has many uncertain factors, such as：Flue diameter, wall thickness
It is unknown etc. real data, it is difficult to determine insertion depth；It has been easy to reel during sampling gun inserts flue, also
The front end deformation of dynamic and static pressure Pitot tube is easily caused, also has no idea to repair, whole branch sampling gun can only be changed, on the one hand used
Cost is too high, on the other hand carries several sampling guns and goes measure field to be inconvenient.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of gas sampling gun for having combined moving static pressure Pitot tube,
Can solve existing gas sampling gun can not repair when dynamic and static pressure Pitot tube deforms, cause can only whole Zhi Genghuan the problem of.
The utility model is achieved through the following technical solutions：
A kind of gas sampling gun provided with combined moving static pressure Pitot tube, including waste gas sampling pipe on handle and
Dynamic and static pressure Pitot tube, the front end of the waste gas sampling pipe connect sampling mouth through Particulate Filter, the dynamic and static pressure Pitot tube by
The back segment and leading portion being connected by detachable attachment mechanism are formed, and the back segment is arranged on handle.
Further scheme of the present utility model is that the detachable attachment mechanism sets threaded connecting cylinder including outer wall,
And the gland for being fitted and connected the connecting plate of an opening end, being threadedly coupled with connecting cylinder, hollow-out parts, dew are provided with the gland
Go out part connecting plate；The end of the back segment and leading portion is each passed through connecting cylinder blind end and connecting plate, in connection tube inner chamber pair
Connect.
Further scheme of the present utility model is that the front end of the leading portion is connected with protective case.
Further scheme of the present utility model is that back segment and the waste gas sampling pipe passes through from sleeve pipe.
Further scheme of the present utility model is that described sleeve pipe outer wall is provided with scale.
The utility model compared with prior art the advantages of be：
First, when the leading portion of dynamic and static pressure Pitot tube is by collision deformation, pull down and change what is crossed in advance through Pitot tube factor check
New leading portion, use cost is effectively reduced, and need to only carry the several leading portions crossed in advance through Pitot tube factor check i.e.
Can, it is easy to carry；
2nd, protective case is protected to the leading portion of dynamic and static pressure Pitot tube, is reduced by collision-deformed probability；
3rd, sleeve pipe is positioned to back segment and waste gas sampling pipe, protected；
4th, scale is easy to grasp the insertion depth of sampling gun, and the leading portion for further reducing dynamic and static pressure Pitot tube is become by collision
The probability of shape.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Gland 9, hollow-out parts, the exposed portion connecting plate of circle are provided with the gland 9；The end difference of the back segment 5 and leading portion 7
Through the blind end of connecting cylinder 10 and connecting plate, docked in the inner chamber of connecting cylinder 10, between back segment 5 and connecting cylinder 10 blind end,
And it is sealedly and fixedly connected respectively by welding or being bonded realization between leading portion 7 and connecting plate；The front end of the leading portion 7 is connected with
Protective case 8, the back segment 5 are arranged on handle 6, and the back segment 5 and waste gas sampling pipe 2 pass through from sleeve pipe 1, described sleeve pipe 1
Outer wall is provided with scale.
Tubaeform enlarging or hose adapter are set in the butt end of back segment 5 and leading portion 7, are easy to pair of back segment 5 and leading portion 7
Connect.
During assembling, the end of back segment 5 and leading portion 7 is docked, and then connecting plate is pressed on the spacious of connecting cylinder 10 by rotary gland 9
Mouth end.
