Description
Technical field
The present invention relates to fluid measurement technical field of tools, particularly a kind of flow sensor.
Background technology
Equipment of the flow sensor as measurement water velocity, can be divided into several major classes such as mechanical, optical profile type, sound wave type,
Higher measuring accuracy is can reach, but electronic circuit is generally set, it is complicated, especially in rate of flow of fluid stabilization or flow
Under the operating mode of fast change interval time length, seem that cost is higher using common current meter.
The content of the invention
The purpose of the present invention is improved and innovated for shortcoming present in background technology and problem, there is provided Yi Zhongjie
The flow sensor that structure is simple, cost is cheap.
The technical scheme is that a kind of flow sensor is constructed, including body, measurement part, described measurement part
The side of body, including elastic plate, vacuole and instruction pipe are arranged on, the vacuole sets the first opening and the second opening, described
First opening connection instruction pipe, the second opening connection elastic plate so that vacuole inside instruction pipe with communicating, and the two of the elastic plate
Face corresponds to respectively inside vacuole and tubular body, and filling indicating liquid and part overflow into instruction pipe in the vacuole, described
Slidable instruction disk is provided with instruction pipe, at the liquid level in instruction pipe, scale is provided with outside the instruction pipe.
In one of the embodiments, the instruction pipe is L-shaped, and one section therein parallel with body direction.
The advantages of the present invention：The present invention is simple in construction, when liquid flows in body, different in flow rate
Under, fluid is different to the pressure of tube wall, is reflected in the extruding to elastic plate, the indicator solution in vacuole is acted so that
Indicating liquid disengaging instruction pipe, promotes the movement of instruction disk, and flow velocity, structure letter can be read according to scale corresponding to instruction disk
Single, cost is cheap, more stable especially suitable for rate of flow of fluid, and the operating mode of change in flow interval time length.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment.
Fig. 2 is the structural representation of one embodiment.
Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing
Give the preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to this paper institutes
The embodiment of description.On the contrary, the purpose for providing these embodiments is made to the disclosure more thorough and comprehensive.
It should be noted that when element be considered as " setting " on another element, it can be direct sets or even
It is connected on another element or may be simultaneously present centering elements.
Unless otherwise defined, all technologies used herein and scientific terminology and the skill of the technical field of the present invention
The implication that art personnel are generally understood that is identical.Term used in the description is intended merely to describe specifically to implement purpose, is not
It is intended to the limitation present invention.
Embodiment 1
As shown in figure 1, a kind of flow sensor, including body 1, measurement part, described measurement portion point are arranged on body
Side, including elastic plate 2, vacuole 3 and instruction pipe 4, the vacuole 3 set the first opening and the second opening, and described first opens
Mouth connection instruction pipe 4, the second opening connection elastic plate 2 so that vacuole 3 communicates with indicating inside pipe 4, and the two of the elastic plate 2
Face corresponds to inside the inside of vacuole 3 and body 1 respectively, and filling indicating liquid 5 and part overflow into instruction pipe 4 in the vacuole 3,
Slidable instruction disk 6 is provided with the instruction pipe 4, the volatilization of indicating liquid 5 can be prevented again, the liquid in instruction pipe 4
At face, scale 7 is provided with outside the instruction pipe 4, instruction disk 6 is both used to refer to scale.
In the above-described embodiments, the instruction pipe can also be L-shaped structure, wherein one section be arranged in parallel with body, make
It is compact-sized to obtain flow sensor, accidental injury can be prevented, as shown in Figure 2.
The present invention is simple in construction, when liquid flows in body, under different in flow rate, fluid to the pressure of tube wall not
Together, it is reflected in the extruding to elastic plate, the indicator solution in vacuole is acted so that indicating liquid disengaging instruction pipe, pushes away
The movement of dynamic instruction disk, flow velocity can be read according to scale corresponding to instruction disk, simple in construction, cost is cheap, especially suitable for
Rate of flow of fluid is more stable, and the operating mode of change in flow interval time length.
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to the present invention
Spirit and scope are defined, and on the premise of design philosophy of the present invention is not departed from, engineers and technicians are to this hair in this area
The all variations and modifications that bright technical scheme is made, protection scope of the present invention, the claimed skill of the present invention all should be fallen into
Art content, all record in detail in the claims.
