Forward flange, restricting orifice and rear flange and fixation are passed through with bolt.A kind of existing orifice flowmeter spiracular plate heavier mass, needs
Two people, which lift, gets to infield, inconvenient to use；A kind of orifice flow timing is installed to need a kind of orifice flowmeter
It is fixedly mounted on bracket, part is more, structure is complicated, manufacturing cost is high, installation cost is high；Structure is complicated, and installation difficulty is big.
Utility model content
To solve the shortcomings of the prior art, the utility model discloses a kind of orifice flowmeter, a kind of holes
Flowmeter design is reasonable, easy to use, can effectively improve the extraction efficiency of gas.
A kind of orifice flowmeter of the utility model, including flowmeter straight tube, the flowmeter length of straight pipe are greater than 10 times of pipes
Diameter；The flowmeter straight tube right end is provided with air inlet, and left end is provided with gas outlet；It turns left on tube body from the right side and is disposed with skin
Trustship pressure port, the first concentration take stomata and the second concentration to take stomata；
The Pitot tube pressure port and air inlet distance are 5-6 times of caliber, the Pitot tube pressure port and the first concentration
Taking stomata distance is 3-4 times of caliber；
A sealing cover is provided with outside the Pitot tube pressure port；First concentration takes stomata and the second concentration to take stomata equal
It is provided with gas nozzle, the first concentration takes stomata and the second concentration to take detachable outside the tube body between stomata to cover a sealed rubber pipe, institute
It states sebific duct both ends and takes stomata and the second concentration that stomata is taken to cover the first concentration.
It is 1-2cm that first concentration, which takes stomata and the second concentration to take air vent aperture,.
Pitot tube pressure port aperture is 1-2cm.
The sealing cover is the rubber ring being located on flowmeter straight tube, and the rubber ring width is greater than Pitot tube pressure port
Aperture.
The flowmeter straight tube is PVC material.
The utility model has the following beneficial effects:
A kind of orifice flowmeter, good seal performance, structure is simple, easy to process, at low cost, can use common pvc pipe
Production；Stomata and Pitot tube pressure port is taken directly to design on tube wall, it is not necessary to which redesign production fixing piece reduces volume and improves
Assembly work efficiency, and reduce assembling manufacturing cost；The device can be direct with the analyzer of existing test tube road Gas explosion burns
It is used in conjunction, instead of a kind of common orifice flowmeter of KLG-3 type.The utility model is light and handy, conveniently, save the cost, compared with routine
A kind of orifice flowmeter for being coupled of the more people of needs, the step of a kind of orifice flowmeter of the utility model simplifies installation and work
Sequence brings great convenience to actual use, effectively reduces manufacturing cost, reduces human resources required for assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1 is flowmeter straight tube, and 2 be air inlet, and 3 be Pitot tube pressure port, and 4 take stomata for the first concentration, and 5 be the
Two concentration take stomata, and 6 be gas outlet, and 7 be sealing cover, and 8 be sealed rubber pipe.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below, but the utility model
Protection scope be not limited to these examples, it is all without departing substantially from the utility model design change or equivalent substitute be included in
Within the protection scope of the utility model.
As shown in Figure 1, a kind of orifice flowmeter of the utility model, including flowmeter straight tube 1, the flowmeter straight tube 1 are long
Degree is greater than 10 times of calibers；1 right end of flowmeter straight tube is provided with air inlet 2, and left end is provided with gas outlet 6；From the right side on tube body
It turns left and is disposed with Pitot tube pressure port 3, the first concentration takes stomata 4 and the second concentration takes stomata 5；
