Abstract
The utility model discloses a fluid flow measuring device. A rotor (3) with a magnetic steel (4) is arranged in the inner cavity of an outer shell (1), and a sensing element (5) is fixed on the position of the outer shell (1) corresponding to the magnetic steel (4). When the fluid flows into the device from a pipe joint and passes through a flow-guiding rack, because of the guiding action of a helical blade, the fluid forms a helical flow so as to push the rotor to rotate. The sensing element arranged on the outer shell detects the signals of the magnetic steel on the rotor so as to output the electrical signals of flow. The utility model solves the insufficiencies of complicated structure, too large volume, inconvenient installation, etc. of the existing measuring device, and has the characteristics of compact structure and convenient installation.
Description
Technical field
The utility model relates to a kind of device that is used to measure fluid flow, and particularly a kind of being applicable to measured little caliber, the mesolow gas of low-viscosity, the measurement mechanism of fluid flow.
Background technology
Existing in the market all kinds flowmeter ubiquity volume is excessive, complex structure, and manufacturing cost is higher, and shortcomings such as inconvenience are installed.
The utility model content
Technical problem to be solved in the utility model provides a kind of fluid flow rate measurement apparatus simple in structure, easy to install, in order to overcome the deficiency of above-mentioned existing procucts.
The technical scheme that its technical matters that solves the utility model adopts is as follows:
A kind of fluid flow rate measurement apparatus comprises shell and the pipe adapter that is installed in shell one end, and the rotor of band magnet steel is installed in the inner chamber of shell (1), is fixed with sensing element on shell and the corresponding position of described magnet steel.
End at described rotor also is equipped with the water conservancy diversion frame of being with helical blade, and rotor and water conservancy diversion frame are installed in the casing.
Between described casing and pipe adapter, holddown spring is installed.
When pipe adapter flowed into this device through the water conservancy diversion frame, because the guide effect of helical blade, fluid formed helical flow, thereby promotes the rotor rotation at fluid.Thereby be contained in the electric signal that sensing element on the shell detects the signal delivery rate of rotor upper magnetic steel.The utility model has solved measurement mechanism complex structure in the past, and volume is excessive, and deficiencies such as inconvenience are installed, and has characteristics simple for structure, easy for installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model rotor.
Fig. 3 is the structural representation of water conservancy diversion frame in the utility model.
Embodiment
As shown in Figure 1, 2, magnet steel 4 is installed on two blades of rotor 3, plays the effect of transmitting the rotor rotation signal in this device.The rotating shaft of rotor 3 is inserted in the axis hole of water conservancy diversion frame 6, then rotor 3 and water conservancy diversion frame 6 is encased in the casing 2 together, forms movement.
Movement, holddown spring 7, pipe adapter 8 are encased in the shell 1 successively, tighten pipe adapter 8, can fix each element.Sensing element 5 is installed in the magnet steel 4 corresponding positions on shell 1 and the rotor 3.
As shown in Figure 3, have helical blade 9 on the water conservancy diversion frame 6.When fluid was flowed through water conservancy diversion frame 6 from pipe adapter 8, because the guide effect of helical blade 9 on the water conservancy diversion frame 6, fluid formed helical flow, rotated thereby promote rotor 3.Thereby be contained in the electric signal that sensing element 5 on the shell 1 detects the magnetic signal delivery rate of rotor 3 upper magnetic steels 4.
Claims (3)
1. fluid flow rate measurement apparatus, comprise shell (1) and be installed in the pipe adapter (8) of shell (1) one end, it is characterized in that: the rotor (3) of band magnet steel (4) is installed in the inner chamber of shell (1), on shell (1) and the corresponding position of described magnet steel (4), is fixed with sensing element (5).
2, fluid flow rate measurement apparatus as claimed in claim 1 is characterized in that: the end at described rotor (3) also is equipped with the water conservancy diversion frame (6) of being with helical blade (9), and rotor (3) is installed in the casing (2) with water conservancy diversion frame (6).
