Connect the top in the flue gas sampling hole 5 in section 2；As shown in fig. 7, pushing down on sampling port lid 6 so that sliding block 63 slides down to horizontal stroke
To chute 22 and the connectivity part of vertical chute 23, sampling port lid 6 is then rotated so that two sliding blocks 63 are respectively in two horizontal concrete chutes 22
Horizontally rotate, connect flue gas sampling hole 5 and required circular hole 611；As shown in figure 8, horizontally rotating sampling port lid 6 so that sliding block 63
The connectivity part of horizontal concrete chute 22 and vertical chute 23 is turned to, sampling port lid 6 to the bottom of vertical chute 23 is pushed down on so that
The top 62 of sampling port lid 6 covers flue gas sampling hole 5.Moving up and down and horizontally rotate by port lid 6 of sampling so that bottom 61
On the circular hole 611 of different-diameter connected with flue gas sampling hole 5 respectively, to reach the purpose of the size for changing flue gas sampling hole 5；
In the presence of outside pumping power, flue gas is inhaled into smoke sampling rifle from flue gas sampling hole 5, but due to flue gas sampling hole 5
Negative pressure in the top of gas sampling gun, flue gas sampling hole 5 is smaller, and the pressure difference inside and outside flue gas sampling hole 5 is smaller, flue gas
Flow is also just smaller, therefore by changing the size in the flue gas sampling hole 5 in different middle splice sections 2, can make to enter flue gas
The flow of the flue gas of thieff hatch 5 is identical, it is ensured that the accuracy of measurement result.
One end of the sampling gun rear 3 is threadedly coupled with middle spelling joint 21, and the other end is provided with sampling gun interface 9；
As shown in figure 9, the sampling gun rear 3 is provided with anti-scalding handle 8 near one end of sampling gun interface 9, it is convenient in flue gas sampling
Grasped during plug, it is to avoid scald one's hand, reduce unsafe factor；The sampling gun rear 3 covers away from one end of sampling gun interface 9
Be provided with for flue gaging hole seal and rise fixation rubber stopper 7, the rubber stopper 7 for ease of plug reverse frustoconic,
In the present embodiment, the rubber stopper 7 is high-temperature resistant rubber plug 7；As shown in Figure 10, rubber stopper 7 is uniformly arranged along its circle center
There is the thermal resistance that different length is plugged with the aperture 71 that heat supply resistance is passed through, aperture 71（Not shown in figure）.
As shown in Fig. 1 and Figure 11, the periphery of the sampling gun top section 1 and middle splice sections 2 is provided with blocks thermal resistance
Buckle 4；During measurement flue-gas temperature, thermal resistance is inserted by the aperture 71 on rubber stopper 7, is fastened on the length of gas sampling gun
On buckle 4 on direction.Preferably, the quantity and rubber of the buckle 4 of the periphery of the sampling gun top section 1 and middle splice sections 2
The quantity of the aperture 71 on plug 7 is consistent and position is mutually correspondingly arranged so that in the middle of sampling gun top section 1 and more piece in splice sections 2
Multiple buckles 4 and aperture 71 be in same straight line on.
In the present embodiment, as shown in figure 12, the buckle 4 includes being connected to sampling gun top section 1 and the middle outside of splice sections 2
The chamber portion 41 of the circular arc in face is integrally formed with the tip 42 for being connected to the opening of chamber portion 41 both sides, tip 42 with chamber portion 41, thermoelectricity
Resistance snaps in chamber portion 41 and is fixed in chamber portion 41 from tip 42, so facilitates blocking and extracting for thermal resistance, and simple structure is convenient
It is practical.The buckle 4 that gas sampling gun is set, not only facilitates the dismounting of thermal resistance, and buckle 4 to divide the thermal resistance of different length
Separate and, reduce thermal resistance influences each other, while influence of the high temperature and high pressure flue gas to thermal resistance can be reduced, prevents thermoelectricity
The deformation of resistance, when gas sampling gun is useful in horizontal flue, can be prevented effectively from thermal resistance and occur to break under fluid matasomatism
Split.
Preferably, as shown in fig. 6, the inner side of the buckle 4 is laid with heat-insulating material 10, in the present embodiment, the thermal insulation
Material 10 is laid on the inside of chamber portion 41, to reduce the heat transfer between thermal resistance and sampling gun, further improves temperature survey
Accuracy.
Preferably, the top of correspondence thermal resistance is provided with thermal shroud on the gas sampling gun, to solve in smoke sampling
