Description
Technical field
The utility model is related to metering field, more precisely, the utility model is related to a kind of based on ultrasonic measurement
Flowmeter or calorimeter.
Background technology
Flowmeter or calorimeter are the instruments for measuring fluid flow, and operation principle is：When ultrasonic beam passes in a liquid
Sowing time, the flowing of liquid will make the propagation time generate small variation, and the variation in propagation time is proportional to the flow velocity of liquid.Zero
During flow, two sensor emissions are identical with the time needed for reception sound wave (uniquely can actually to measure the skill of zero delivery
Art).When liquid flows, the acoustic transit time of countercurrent direction is more than the acoustic transit time of downbeam.
The flowmeter of this ultrasonic type is when installation, it is necessary to which ultrasonic probe is inserted into pipeline, that is to say, that
It needs to punch on pipe laying, so as to the insertion of ultrasonic probe.

It states position opposite with the first detecting head, the second detecting head on the inner wall of ring flange and is provided with reflecting surface；The probe rod is located at
One end on the outside of ring flange is provided with dial plate.
Optionally, the distribution arrangement of the first detecting head in the main body, the second detecting head is vertical with the end face of ring flange.
Optionally, it is provided with to be caught in the card slot of main body on the ring flange inner wall；It is also set up on the probe rod
Be useful for locking nut probe rod being locked on ring flange.
The ultrasonic flowmeter or calorimeter of the utility model, ring flange may be mounted between two pipelines, that is,
One of end face of ring flange is connected with one of connecting pipe, another end face is connected with another connecting pipe,
So as to which the ultrasonic flowmeter of the utility model or calorimeter are mounted between two connecting pipes.When liquid is in connecting pipe
, can be by the inner cavity of ring flange during middle flowing, and formed between the first detecting head, the second detecting head and reflecting surface
Detected by sound wave circuit, the calculating of flow is realized.
Description of the drawings
Fig. 1 shows the structure diagram of the utility model ultrasonic flowmeter or calorimeter.
Specific embodiment
The technical issues of in order to solve the utility model, use technical solution, obtain technique effect it can be readily appreciated that
With reference to specific attached drawing, specific embodiment of the present utility model is described further.
With reference to figure 1, the utility model provides a kind of ultrasonic flowmeter or calorimeter, including the flange with inner cavity
Disk 3 and the probe rod 2 being extend into from 3 side wall of ring flange in its inner cavity.
The ring flange 3 of the utility model is in the circular dish structure with inner cavity, and one end of probe rod 2 is outside ring flange 3
Side is penetrated into the inner cavity of ring flange 3.Wherein, probe rod 2 is located at the one end in the outside of ring flange 3 and is provided with dial plate 1, on dial plate 1
Display screen is provided with, can be used to show the data message of the flowmeter.
The one end of the probe rod 2 in 3 inner cavity of ring flange is provided with main body 40, is set in the main body 40 oriented opposite
The first detecting head 41, the second detecting head 42 of both sides extension.That is, the first detecting head 41, the second detecting head 42 are from main body
It extends out on 40, and the first detecting head 41 and the second detecting head 42 extend to the opposite both sides of main body 40 so that main body 40, the
Approximate one detecting head 41, the second detecting head 42 are in " people " font.
The position opposite with the first detecting head 41, the second detecting head 42 is provided with reflecting surface on the inner wall of the ring flange 3
5.The reflecting surface 5 is arranged on the inner wall of ring flange 3, and opposite with the first detecting head 41, the second detecting head 42.This allows for
The sound wave that one detecting head 41 is launched can be detected after the reflection of reflecting surface 5 by the second detecting head 42.Second detecting head
42 sound waves launched can be detected after the reflection of reflecting surface 5 by the first detecting head 41.
The ultrasonic flowmeter or calorimeter of the utility model, ring flange may be mounted between two pipelines, that is,
One of end face of ring flange is connected with one of connecting pipe, another end face is connected with another connecting pipe,
So as to which the ultrasonic flowmeter of the utility model or calorimeter are mounted between two connecting pipes.When liquid is in connecting pipe
It, can be by the inner cavity of ring flange, and by between the first detecting head 41, the second detecting head 42 and reflecting surface 5 during middle flowing
Detected by the sound wave circuit of formation, the calculating of flow is realized.
In one preferred embodiment of the utility model, the first detecting head 41, second detection in the main body 40
First 42 distribution arrangement is vertical with the end face of ring flange 2 so that liquid can flow to another detecting head from a detecting head
Position, this is beneficial to measurement.
It may further be preferable that it is provided with to be caught in the card slot 6 of main body 40 on 3 inner wall of ring flange；In the spy
It is additionally provided with for probe rod 2 to be locked at the locking nut on ring flange 3 on head rod 2.Card slot 6 is formed in the interior of ring flange 3
The position of probe rod 2 being pierced by wall so that main body 40 can be caught in the card slot 6, and can be by locking nut by probe rod 2
Locking.Using such structure design so that when in use, it is ensured that the distribution of the first detecting head 41, the second detecting head 42
Direction is vertical with the end face of ring flange 3.
When transport, main body 40 from card slot 6 can be deviate from, and rotate probe rod 2 so that the first detecting head 41, second
Detecting head 42 is in the inner cavity of ring flange 3, and to protect the first detecting head 41, the second detecting head 42 without damage, this is beneficial to
Transport.
The utility model has carried out detailed explanation by preferred embodiment.However, by studying carefully above,
Variation and increase to each embodiment are obvious for those of ordinary skill in the art.The intention of applicant
It is that all these variations and increase all fall in the scope protected in the utility model claims.
