Abstract
The utility model belongs to a measuring instrument for physical laboratories, in particular to a fluid velometer, which comprises a disk surface 1 and a pointer 6, one side of a central shaft 3 is connected with a fan-shaped velocity measurement plate 2 which is equipped with a velocity measurement opening 5 corresponding to the pointer 6. The pointer 6 is connected with a friction ring 4. Friction force generated during sliding of the pointer 6 and the friction ring 4 can be adjusted, and the parameter thereof directly decides the scale of the velocity measurement plate 2. Because the velocity measurement plate 2 and the disk surface are combined, the direction of fluid can be viewed through the disk surface, and the speed of fluid can be viewed through the velocity measurement plate. Therefore, the utility model can achieve fine fluid velocity measurement effect.
Description
Technical field
The utility model belongs to the surveying instrument that the physics laboratory uses, particularly a kind of fluid knotmeter.
Background technology
In the actual life, the instrument of measuring fluid is various, and some is measured by pressure differential, and some realizes the purpose measured by sensor installation.And in daily life, the windmill that child plays is met wind and just can be rotated rapidly, can judge the size of wind speed to a certain extent, and in the laboratory, use the windmill principle, simplicity of design, economical and practical fluid measurement instrument are used to explain that physical phenomenon is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of fluid knotmeter.
The utility model is achieved in that it comprises card, pointer, and described central shaft one side connects velocity measurement plate, and described velocity measurement plate is fan-shaped, and velocity measurement plate is provided with the mouth that tests the speed corresponding with pointer.
Described pointer is connected with friction ring.
The friction force that produces when described pointer and friction ring slide can be adjusted, and its parameter directly determines the scale of velocity measurement plate.
Described card have indicate fluid to scale, the direction that velocity measurement plate is corresponding with card is a flow direction.
The utility model can be seen flow direction because velocity measurement plate and card are combined by card, can see fluid velocity by velocity measurement plate.So can reach the effect that good fluid tests the speed.
Description of drawings
The vertical view of Fig. 1, the utility model Fig. 2.
Fig. 2: the utility model embodiment 1 structural representation.
Embodiment
Embodiment 1: in the present embodiment, it comprises card 1, pointer 6, and described central shaft 3 one sides connect velocity measurement plate 2, and described velocity measurement plate 2 be fan-shaped, and velocity measurement plate 2 is provided with the mouth 5 that tests the speed corresponding with pointer 6.
Described pointer 6 is connected with friction ring 4.
The friction force that described pointer 6 produces when sliding with friction ring 4 can be adjusted, and its parameter directly determines the scale of velocity measurement plate 2.
Described card 1 has the scale of indicating wind direction, and the direction that velocity measurement plate is corresponding with card is a flow direction.
The utility model is used for measuring wind or water flow velocity, when fluid tests the speed mouthfuls 5 during by measuring instrument, and pointer, when velocity measurement plate rotation back stops, the scale on the pointed velocity measurement plate is a fluid velocity, the direction that velocity measurement plate points to card is a flow direction.The fluid velocity power differs, and corresponding scale also differs, thereby can select data analysis, reaches the purpose of experiment.
