The electric control valve supporting the actuator is my company independent design, research and development, production. The actuator is composed of motor, gear reducer, connecting sleeve, limit switch, torque (thrust) limiting device, hand wheel, automatic disengagement device of hand wheel, mechanical valve position display, LCD display, control circuit board and other devices necessary for safe and stable operation. The whole device is completely sealed, suitable for outdoor operation, and has the function of debugging without opening the cover. Any adjustment, debugging, fault diagnosis and modification of the setting value of the actuator can be carried out by manual operation or panel operation, without the need to disassemble the sealing end cover of the actuator and without any special tools.
Intelligent flow measurement and control instrument
The WZF-0808A type intelligent flow measuring and controlling instrument designed, developed and produced by our company is used for the terminal intelligent control device of industrial engineering measurement and control system. It has low power consumption, supports solar power supply, adopts DC24V power supply, and works continuously for more than 120 hours without lighting. In line with PetroChina A11 standard, it supports local display and remote setting of parameters such as instantaneous flow rate and injection. Control accuracy of 0.5%, with patent protection. The measurement accuracy of vortex flowmeter can reach 0.5%.
The WZL electromagnetic flowmeter independently designed, developed and produced by our company has the characteristics of simple structure, high measurement accuracy, long service life, simple operation and easy maintenance. The product is widely used in metallurgy, chemical industry, petroleum, urban construction, environmental protection, food and other fields, reliable measurement of water, tap water, sewage, diesel, gasoline and low viscosity crude oil and other liquid volume flow.
