Description
Technical field
The utility model belongs to flow measurement instrument technical field, and in particular to a kind of electromagnetic flowmeter of resistance to negative pressure.
Background technology
At present, when measuring river, lake and channel when the flow velocity of the water body of open channels, the current meter species of use is more,
Mainly there are ultrasonic flow meter, rotary cup (mechanical) flowmeter, Doppler type flowmeter and electromagnetic type flow meter, wherein super
The precision and durability of sound wave type flowmeter and rotary cup flowmeter are poor, and Doppler type flowmeter is expensive, to test
Environmental requirement is stringent.Electromagnetic type flow meter is a selection well for measuring flow velocity of river.
But traditional electromagnetic flowmeter has the following disadvantages, when termination of pumping, negative pressure can be generated in pipeline, rubber is caused to serve as a contrast
In or tetrafluoro lining from water meter inner wall remove, even come off when serious so that Causing Flowmeter Damages.
Utility model content
The defects of easily being removed the purpose of the utility model is to overcome lining existing in the prior art with water meter, provides
A kind of electromagnetic flowmeter of resistance to negative pressure.
Technical solution is used by the utility model solves its technical problem：
A kind of electromagnetic flowmeter of resistance to negative pressure including water meter, is arranged on the flange at water meter both ends, and feature exists
In：Lining of the lining on the water meter inner wall is further included, the lining includes being fitted on the water meter inner wall
Tubular liner and tubular liner both ends end face lining, the end face lining be mounted on the flange outer surface；The pipe
There is at least one layer of stainless steel cloth in shape lining.
Further, the tubular liner obtains middle part as one layer of stainless steel cloth, and end is two layers of stainless steel cloth.
Further, the outer surface of the tubular liner has multiple reinforcing protrusions, and the inside of the water meter has
It is multiple to reinforce the corresponding grooves of protrusion with described, the tubular liner be pasted onto on the water meter inner wall and groove in.
Further, the lining is rubber lining.
Further, the lining is tetrafluoro lining.
A kind of advantageous effect of the electromagnetic flowmeter of resistance to negative pressure of the utility model is：
1st, stainless steel wire stratum reticulare is added in the inside of lining, as shape support, makes lining that there is certain rigidity, again
It ensure that the flexibility needed for it, when generating negative pressure, stainless steel cloth can bear the pressure of interior receipts, ensure that lining does not allow mutability
Shape, and then lining is just not easy to remove with water meter inner wall.
2nd, reinforcing protrusion is added in the outer surface of lining, on the one hand increases the adhesive surface of lining and water meter inner wall
Product, enhances sticking strength, even if on the other hand there is negative pressure, reinforces protrusion and is also not easy to deviate from from groove, further subtract
The risk that small lining is removed or deviate from water meter.
3rd, since the end of water meter is easier to bear larger negative pressure, so in order to ensure safety, in tubular liner
End set double-layer stainless steel silk screen.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of the electromagnetic flowmeter of 1 resistance to negative pressure of the utility model embodiment；
Fig. 2 is the schematic diagram of the electromagnetic flowmeter of 2 resistance to negative pressure of the utility model embodiment.
In figure：1st, water meter, 2, flange, 3, lining, 31, tubular liner, 32, end face lining, 33, stainless steel cloth,
34th, protrusion is reinforced.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
Embodiment 1
As shown in Figure 1, a kind of electromagnetic flowmeter of resistance to negative pressure of the present embodiment, including water meter 1, is arranged on water meter pipe
Lining 3 of the flange 2 and lining at 1 both ends of road on 1 inner wall of water meter, lining 3 can be rubber lining or tetrafluoro lining, serve as a contrast
In 3 by be adhesive on 1 inner wall of water meter and 2 outer surface of flange on.Wherein, lining 3 includes being fitted in water meter 1
The end face lining 32 at 31 both ends of tubular liner 31 and tubular liner on wall, end face lining 32 are mounted on the outer surface of flange 2；Pipe
There is at least one layer of stainless steel cloth 33 in shape lining 31.In the present embodiment, there is one layer of stainless steel cloth in tubular liner 31
33, because the needs of installation, stainless steel cloth 33 is not provided in end face lining 32.
Embodiment 2
As shown in Fig. 2, it is one layer of stainless steel cloth 33 that the present embodiment tubular liner 31, which obtains middle part, end is stainless for two layers
Steel wire 33.So disclosure satisfy that the end of water meter 1 often has the needs of larger negative pressure.
In order to further reinforce the sticking strength of lining 3 and water meter 1, ensure that lining 3 is not easy to fall off, this reality
It applies in example, the outer surface of tubular liner 31 has multiple reinforcing protrusions 34, and the inside of water meter 1 has multiple and reinforces raised
34 corresponding grooves, tubular liner 31 be pasted onto on 1 inner wall of water meter and groove in.
The utility model, as shape support, works as negative pressure by adding in one or more layers stainless steel cloth 33 in lining 3
During generation, stainless steel cloth 33 undertakes the pressure of interior receipts, remains intact lining 3.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With new.By the obvious changes or variations that the spirit of the utility model is extended out still in the protection of the utility model
Among scope.
