Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, and specifically relates to a simple circuit high-frequency flow meter. Background Technique

[0002] Measurement is the eye of industrial production. Flow measurement is one of the components of measurement science and technology. It has a close relationship with the national economy, national defense construction, and scientific research. Its principle is that when a liquid passes through a flow meter, it drives the internal gear of the flow meter to rotate. Two magnetic steels on the gear intermittently give magnetic signals, and the circuit Hall captures the signals and feeds back through the M3 signal to emit light. However, the original high frequency was through the flywheel and the capillary corresponding to the magnetic steel on the gear. When the frequency was too high, the circuit Hall was overwhelmed and could not accurately capture each signal.

[0003] To solve the above problems, we urgently need a simple circuit high-frequency flow meter. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a simple circuit high-frequency flow meter to solve the problem that in the above-mentioned background technique, the original high frequency was through the flywheel and the capillary corresponding to the magnetic steel on the gear. When the frequency was too high, the circuit Hall was overwhelmed and could not accurately capture each signal.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A simple circuit high-frequency flow meter includes a housing. A wheel shaft is arranged inside the housing. A gear is sleeved on the outer surface of the wheel shaft. A magnetic steel is fixedly installed at the top of the gear. A sealing ring is movably attached to the outer surface of the upper side of the housing. A lid is movably attached to the outer surface of the upper side of the sealing ring. Four first fixing nuts are inserted into the lid. A circuit cover is movably attached to the outer surface of the upper side of the lid. A capillary is fixedly installed at the bottom of the circuit cover. A circuit Hall is fixedly installed at the bottom end of the capillary. Two second fixing nuts are inserted into the circuit cover. An M3 signal is arranged on the outer surface of the upper side of the circuit cover.

[0006] Preferably, a circuit hole is opened in the lid, and the capillary is inserted into the circuit hole.

[0007] Preferably, the circuit Hall is located at the lower end of the circuit hole, and the magnetic steel is located directly below the circuit Hall.

[0008] Preferably, the lower end of the M3 signal penetrates through the capillary and is electrically connected to the circuit Hall.

[0009] Preferably, the first fixing nut is threadedly connected to the inside of the housing.

[0010] Preferably, the second fixing nut is threadedly connected to the inside of the lid.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In this simple circuit high-frequency flowmeter, a wheel axle is arranged inside the housing. A gear is sleeved on the outer surface of the wheel axle. A magnetic steel is fixedly installed at the top of the gear. A sealing ring is movably attached to the outer surface of the upper side of the housing. A lid is movably attached to the outer surface of the upper side of the sealing ring. Four first fixing nuts are inserted into the lid. A circuit cover is movably attached to the outer surface of the upper side of the lid. A capillary tube is fixedly installed at the lower side of the circuit cover. A circuit Hall is fixedly installed at the bottom end of the capillary tube. Two second fixing nuts are inserted into the circuit cover. An M3 signal is arranged on the outer surface of the upper side of the circuit cover. The flowmeter is installed on the pipeline, and the liquid is allowed to flow through the inside of the housing, driving the gear inside the housing to rotate. The magnetic steel at the top of the gear generates a magnetic field signal, and the circuit Hall below the capillary tube captures the signal and gives a light feedback through the connected M3 signal. Since when the gear rotates, both the magnetic steel and the circuit Hall are limited inside the circuit hole without displacement, it can well avoid inaccurate signal capture caused by interval or displacement.
