TJP65FH DC Gear Motor for Valve Flowmeters: High-Precision Torque Core, Driving Accurate Measurement & Intelligent Regulation

The TJP65FH DC gear motor is an industrial-grade precision drive component customized for valve flowmeters, integrating constant torque stable output, high-precision stroke control, anti-corrosion sealed structure and low-speed reliable transmission. Powered by 24V/48V industrial low-voltage DC power supply (compliant with industrial automation equipment electrical specifications), it achieves precise angular rotation, stepless speed regulation and self-locking positioning of the valve core, supporting core functions of intelligent valve flowmeters such as medium flow accurate measurement, real-time valve opening adjustment, closed-loop flow control and remote intelligent regulation for water supply and drainage, petroleum chemical, industrial fluid, HVAC pipeline and municipal water conservancy scenarios. It meets the stringent industrial-grade requirements of valve flowmeters for drive precision, measurement accuracy, structural durability and environmental adaptability in complex industrial pipeline working conditions (medium corrosion, pressure fluctuation, temperature change), and matches the intelligent automation needs of industrial fluid flow control systems.

Working Principle

Valve flowmeters rely on the TJP65FH motor as the core power drive for valve core regulation + flow measurement linkage—the key to realizing accurate flow measurement and closed-loop intelligent control of pipeline media. The motor converts industrial 24V/48V DC power into uniform, low-speed mechanical rotation via its optimized reinforced precision gear reduction system and high-efficiency electromagnetic structure, and cooperates with the valve flowmeter’s worm gear, lead screw or crankshaft transmission mechanism to convert rotary motion into precise angular adjustment of the valve core (0-90° stepless opening), with a customizable output torque of 5-25N·m and rotation speed of 2-10°/s, perfectly matching the drive load of industrial pipeline valves of different calibers (DN25-DN100). The motor is seamlessly integrated with the flowmeter’s sensor and intelligent control module: the flow sensor real-time collects the medium flow data in the pipeline and transmits it to the control system; when the actual flow deviates from the set value, the control system issues a regulation command to the motor, which drives the valve core to fine-tune the opening in real time—increasing the opening to boost flow, reducing the opening to reduce flow, realizing closed-loop dynamic control of pipeline flow with measurement accuracy up to ±1%. Its self-locking performance of the gear transmission mechanism ensures the valve core is firmly positioned at the set opening, without displacement due to pipeline medium pressure fluctuation or water hammer impact, maintaining stable flow measurement and regulation accuracy. For abnormal working conditions (such as pipeline overpressure, medium blockage), the motor receives the control system’s signal to drive the valve core to quickly open/close for emergency protection, avoiding pipeline safety hazards.

Core Advantages

Adapted to the industrial pipeline application characteristics of valve flowmeters such as precision drive, measurement accuracy and complex working condition adaptation, the TJP65FH motor features a perfect balance of industrial-grade precision, stable torque drive and intelligent linkage, with outstanding scenario adaptability:

1. High-precision angular drive & valve core positioning: Industrial-grade high-precision gear transmission with a rotation accuracy of ±0.2°, realizing fine-tuning of the valve core opening with minimal step size (0.5°), matching the flowmeter’s high-precision measurement demand; the precise positioning of the valve core ensures the flow regulation error is controlled within ±1%, meeting the accuracy requirements of industrial fluid quantitative transmission and process control.

2. Constant torque stable output, adapt to pipeline pressure fluctuation: Customizable constant torque output (5-25N·m) with no torque attenuation during long-term operation, able to drive the valve core to stably adjust the opening even under pipeline medium pressure fluctuation (0.1-1.6MPa) and water hammer impact; effectively overcoming the resistance of the valve core and pipeline medium, avoiding motor stalling or valve core jamming, and ensuring continuous stable flow control.

4. Self-locking structural design, maintain stable valve opening: The integrated worm gear transmission self-locking structure of the motor realizes mechanical self-locking after the valve core is positioned, without additional braking components; effectively resisting the thrust of pipeline medium on the valve core, avoiding valve core displacement and flow measurement deviation caused by pressure change, and maintaining long-term stable flow regulation effect.
