Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
It refer to accompanying drawing 1-3, a kind of flowmeter for reducing measurement error, including the first pipeline 1 and be fixedly connected on institute
The second pipe 2 of the both sides of the first pipeline 1 is stated, is respectively fixed with ring flange 3 on the second pipe 2 of the both sides, described in both sides
In two pipelines 2, it is fixed with connecting rod 31 in the horizontal direction respectively, axle sleeve 32 is rotatably installed in the connecting rod 31,
Circumference is fixed with turnover panel 33 on the axle sleeve 32.
In the present embodiment, by being provided with turnover turnover panel 33 in the second pipe 2 described, when entering the second pipe
When on turnover panel 33, current can slow down flow action in road 2, so as to realize the purpose for reducing flow rate of liquid, so as to enter one
The error for reducing flow rate of liquid measurement of step.
Emphatically referring to the drawings 1 bearing, and the axle please be fixed between the inwall and the connecting rod 31 of the axle sleeve 32
It is sealing state between set 32 and the connecting rod 31.
By the effect of axle axle, the purpose that axle sleeve 32 rotates in connecting rod 31 can be achieved；Further, by by axle sleeve
Sealing state between 32 and connecting rod 31, so as to can ensure that bearing waterproof, avoid bearing damage.
Please be emphatically referring to the drawings 2, the even circumferential of turnover panel 33 is provided with four pieces altogether, and the turnover panel 33 described in four pieces is in
" ten " cross-fixing is on the outer wall of axle sleeve 32.
Four guiding gutters 34 have been respectively uniformly distributed respectively on the outer wall of every piece of clockwise direction side of turnover panel 33, and
