Embodiment
Below in conjunction with accompanying drawing, and other technical characteristic above-mentioned to the utility model and advantage are carried out clearly and completely
Description, it is clear that described embodiment is only section Example of the present utility model, rather than whole embodiments.
Referring to Figures 1 and 2, a kind of gas flowmeter, including housing 1 and the stream on housing 1 are present embodiments provided
Integrating instrument 2 is measured, housing 1 includes the detection section 12 that diversion section 11 connects with diversion section 11, and flow integrator 2 is located at detection section 12；
The junction of diversion section 11 and detection section 12 is provided with the deflector 3 for being used for introducing gas into diversion section 11, detects the side wall of section 12
Provided with the external via 4 connected, flow integrator 2 be provided with end insertion detection section 12 gas flow sensor 5.
By taking above-mentioned technical scheme, due to the presence of deflector 3, can produce the gas importing of diversion section 11
Detect the trend of section 12.Here, the gas of diversion section 11 is mainly imported into detection section 12 or in detection section 12 via 4,
It can make diversion section 11 and the extraneous gas part importing detection section 12 for producing air pressure, making in diversion section 11.Also pass through simultaneously
Deflector 3 stops solid bulky grain, realizes the detection gas of gas flow sensor 5 in detection section 12.
Reference picture 2, present embodiments provide a kind of gas flowmeter, its via 4 relative to gas flow sensor 5 end
Portion is closer to flow integrator 2.
By taking above-mentioned technical scheme, because gas flow sensor 5 needs more fully to contact with gas, because
This, via 4 is arranged on the end rear of gas flow sensor 5.Gas is entering the external world from detection section 12 by via 4
During, gas flow sensor 5 can be made and more fully contacted with gas.
Reference picture 2 and Fig. 3, a kind of gas flowmeter is present embodiments provided, its diversion section 11 includes inlet end 111 and gone out
Gas end 112, deflector 3 include the first plate body 31 and the second plate body 32, and the first plate body 31 is vertical with the length direction of diversion section 11
And connected with the second plate body 32, the length direction of the second plate body 32 and diversion section 11 exist angle and and detection section 12 it is interior
Wall connects, and the junction of the second plate body 32 and detection section 12 is relative to inlet end 111 closer to outlet side 112.
By taking above-mentioned technical scheme, in fact, gas enters diversion section 11 from the inlet end 111 of diversion section 11,
Again diversion section 11 is left from the outlet side 112 of diversion section 11.Here, the first plate body 31 is arranged to the length side with diversion section 11
To vertical, certain drainage can be played a part of and stop solid bulky grain.The connection of second plate body 32 is arranged to and led
There is the flow velocity that angle can increase gas in the length direction of stream section 11, contribute to gas flow sensor 5 to detect.
Reference picture 2, a kind of gas flowmeter is present embodiments provided, the end of its gas flow sensor 5, which is not stretched into, leads
Flow section 11.
By taking above-mentioned technical scheme, diversion section 11 is not stretched into the end of gas flow sensor 5 in figure,
Because the gas in diversion section 11 also has solid bulky grain, stretch into and easily cause gas flow sensor 5 and damage.
Reference picture 2, a kind of gas flowmeter is present embodiments provided, its gas flow sensor 5 and flow integrator 2 are solid
Fixed connection, flow integrator 2 and detection section 12 are detachably connected.
By taking above-mentioned technical scheme, can conveniently it install, because gas flow sensor 5 is integrally fixed at flow product
Calculate on instrument 2, only need to be by flow integrator 2 mounted in the port of detection section 12 during installation.Without pacifying in diversion section 11
Gas flow sensor 5 is filled, it is more convenient.
Reference picture 2 and Fig. 3, a kind of gas flowmeter is present embodiments provided, its flow integrator 2 is provided with display screen 6.
By taking above-mentioned technical scheme, it is possible to achieve digital display, user is more intuitively read data.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
The detailed description of step, it will be appreciated that the foregoing is only specific embodiment of the utility model, be not used to limit this reality
With new protection domain.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it
