Embodiment 1

[0048] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment proposes a non-stationary fluid pressure measurement device, which includes a hard shell 1, and the inside of the hard shell 1 is provided with a pressure detection structure 2 and a driving mechanism 3, and the driving mechanism 3 is located on one side of the pressure detection structure 2 , the pressure detection structure 2 reflects the sensed fluid pressure through the movement of the light irradiation point, and the driving mechanism 3 operates according to the movement of the light irradiation point. One side of the hard shell 1 is provided with an observation part casing 5, and the observation part casing 5 The internal medium can be replaced according to actual needs. There is a disassembly sealing mechanism 4 between the hard casing 1 and the observation part casing 5. The disassembly sealing mechanism 4 is convenient for disassembling the h...

Embodiment 2

[0050] The scheme in embodiment 1 is further introduced below in conjunction with specific working methods, see the following description for details:

[0051] As a preferred embodiment, on the basis of the above method, further, the pressure detection structure 2 includes a thin film 21 fixedly connected to the inside of the hard shell 1 and away from the side of the drive mechanism 3, when the external pressure is greater than the internal pressure of the hard shell 1 , the thin film 21 is deformed, and the surface of the thin film 21 close to the driving mechanism 3 is coated with a reflective layer 22. When the thin film 21 is deformed, the path of the light reflected by the reflective layer 22 changes, and the inner wall of one side of the hard shell 1 is embedded with a The reflective mirror 24 reflects the light reflected by the reflective layer 22 again, and enlarges the moving distance of the light point. The other side of the hard shell 1 is embedded with a light sour...

Abstract

The application provides a non-stationary fluid pressure measuring device and its use method, which are used in the field of measuring force, stress, torque, work, mechanical power, mechanical efficiency or fluid pressure, including a hard shell, and the internal device of the hard shell is There is a pressure detection structure and a driving mechanism, the driving mechanism is located on one side of the pressure detection structure, an observation part casing is provided on one side of the hard casing, and a disassembly and sealing mechanism is arranged between the hard casing and the observation part casing An assembling mechanism is provided inside the side of the hard shell and the observation part shell facing each other. In this application, through the combined use of the set drive mechanism and the data observation mechanism, the pressure received by the membrane is expressed through the deformation of the spring, and the membrane remains undeformed when the fluid pressure is measured, which solves the problem of the membrane in the prior art. After being deformed by pressure, when the fluid passes through the deformed film, the flow velocity changes, resulting in inaccurate data of fluid pressure measurement.

Description

technical field [0001] The present invention relates to the field of measuring force, stress, torque, work, mechanical power, mechanical efficiency or fluid pressure, in particular to a fluid pressure measuring device, in particular to a non-static fluid pressure measuring device and its usage method. Background technique [0002] Fluid pressure can be defined as: Considering a certain plane inside the fluid, when there is no relative motion of the fluid on both sides of the plane, the force on any unit area on the surface; from a microscopic point of view, pressure is the result of molecular motion colliding with the container wall The performance of the average force, now the fluid pressure measurement usually measures the static pressure of the fluid. [0003] The working principle of the thin-film pressure sensor is to use the deformation of the film to measure the fluid pressure. When the fluid is flowing, the fluid will be affected by the deformed film when it passes t...
