It counts.
Utility model content
One, technical problems to be solved
The utility model for drawbacks described above present in the prior art, solve prior art interval dirt flowmeter every
Dirty effect is poor, counts the problem of inaccuracy.
Two, technical solution
In order to solve the above technical problems, the utility model provide it is a kind of novel every dirty flowmeter, it is novel every dirty flowmeter packet
It includes: number chamber shell and fluid cavity shell；
Be provided with impeller in fluid cavity shell, impeller can by fluid driving and rotate；
Fluid cavity shell and count and be formed with antifouling chamber between chamber shell, it is antifouling it is intracavitary be provided with lower magnetic and pass circle, lower magnetic passes circle packet
Include magnetic biography portion and driving section；One end of the transmission shaft of impeller is protruded into antifouling intracavitary, and cooperates with driving section, to drive lower magnetic to pass circle
Rotation；
It counts to be provided in chamber shell and passes circle for the counting mechanism of counting and upper magnetic, upper magnetic passes the drive that circle passes circle in lower magnetic
Lower rotation, upper magnetic pass circle for driving counting mechanism to count；
The side of fluid cavity shell is provided with water inlet, is provided with water outlet above water inlet.
Wherein, the water inlet exterior circumferential of fluid cavity shell is provided with filter screen.
Wherein, the diameter of filter screen upper end is 0.5mm smaller than the diameter every the lower end of dirty flowmeter, filter screen upper end
Interference clamping is formed with every the lower end of dirty flowmeter by the deformability of itself.
Wherein, filter screen is made of polytetrafluoroethylplastic plastic.
Three, beneficial effect
Compared with prior art, one kind provided by the utility model is novel every dirty flowmeter, independent antifouling by being arranged
Chamber not will receive the influence of pollution in fluid so that being located at antifouling intracavitary lower magnetic and passing circle, and at the same time, this setup can
The transmission ratio between enclosing is passed to reduce impeller and lower magnetic, to effectively raise count accuracy；By installing filter screen 7 additional,
The fluid for entering fluid cavity shell can be filtered, to reduce pollution to the influence every dirty flowmeter, be improved every dirty flowmeter
Service life.
Detailed description of the invention
Fig. 1 is the novel cross-sectional view every dirty flowmeter of the utility model；
In figure: 1 for upper magnetic pass circle, 2 be lower magnetic pass circle, 3 be antifouling chamber, 4 be water outlet, 5 be impeller, 6 be water inlet, 7
It is magnetic biography portion for filter screen, 21,22 is driving section.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment cannot be used to limit the scope of the utility model for illustrating the utility model.
Embodiment 1:
As shown in Figure 1, comprising: upper magnetic passes circle 1, lower magnetic passes circle 2, magnetic biography portion 21, driving section 22, antifouling chamber 3, water outlet 4,
Impeller 5, water inlet 6 and filter screen 7；
Be provided with impeller 5 in fluid cavity shell, impeller 5 can by fluid driving and rotate；
It is formed with antifouling chamber 3 between fluid cavity shell and counting chamber shell, lower magnetic is provided in antifouling chamber 3 and passes circle 2, lower magnetic passes circle
2 include magnetic biography portion 21 and driving section 22；One end of the transmission shaft of impeller 5 is protruded into antifouling chamber 3, and is cooperated with driving section 22, with
Lower magnetic is driven to pass 2 rotation of circle；
It counts to be provided in chamber shell and passes circle 1 for the counting mechanism of counting and upper magnetic, upper magnetic passes circle 1 and passes circle 2 in lower magnetic
Lower rotation is driven, upper magnetic passes circle 1 for driving counting mechanism to count；
The side of fluid cavity shell is provided with water inlet 6, and water outlet 4 is provided with above water inlet 6；It is independent anti-by being arranged
Dirty chamber not will receive the influence of pollution in fluid, at the same time, this setup so that being located at antifouling intracavitary lower magnetic and passing circle
Impeller 5 can be reduced and lower magnetic passes the transmission ratio enclosed between 2, it is 125/160 that impeller 5 and lower magnetic, which pass the transmission ratio between circle 2, from
And effectively raise count accuracy.
When work, for fluid along 6 incoming fluid chamber housing chamber of water inlet, fluid driven impeller 5 makes impeller 5 rotate, leaf
The driving section 22 that wheel 5 then drives lower magnetic to pass circle 2 rotates, and drives magnetic biography portion 21 to rotate together while driving section 22 rotates, under
Magnetic passes circle 2 and passes circle 1 because of magnetic interaction with upper magnetic, and final upper magnetic passes circle 1 and rotates under the drive that lower magnetic passes circle 2, thus band
Dynamic counting mechanism counts, and fluid is finally flowed out through water outlet 4.
Embodiment 2:
Compared to embodiment 1, embodiment 2 is arranged in 6 exterior circumferential of water inlet of fluid cavity shell on the basis of embodiment 1
There is filter screen 7,7 upper end of filter screen forms interference clamping with every the lower end of dirty flowmeter by the deformability of itself；It crosses
Strainer 7 is made of polytetrafluoroethylplastic plastic；By installing filter screen 7 additional, the fluid for entering fluid cavity shell can be filtered, be subtracted
Enter the pollution in fluid cavity shell less, to reduce pollution to the influence every dirty flowmeter, improves the service life every dirty flowmeter.
Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill people of the art
Member for, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
