Description of electric ash discharge ball valve in temperature control system
Ash ball valve is mainly used in blast furnace dust removal system, mainly to control the dust containing gas, containing particles of liquid, powder and other media, is an important executive body in industrial automation control system. According to the transmission mode, the ash unloading ball valve is mainly divided into manual ash unloading ball valve, pneumatic unloading ball valve, hydraulic ash unloading ball valve, electric ash unloading ball valve, etc.
The calibration temperature of the electric ash unloading ball valve can be set on the panel of the electric ash unloading ball valve, and the data can also be set under the upper computer. P, I, D parameters can be modified in the electric ash discharge ball valve panel. If in the "manual state", the upper and lower keys can be used to open and close the valve locally, and the measured temperature is displayed on the LCD screen in real time and transmitted to the upper computer in real time. In case of unexpected phenomena such as power failure, the electric ash unloading ball valve can be closed on site with a manual crank.
The basic situation of the electric ash unloading ball valve project: after the static air is heated by the heat exchanger, the relatively constant air volume is sent to the incubation room, and the temperature of the air supply is required to be relatively constant. The heating source is steam, and the distributed control mode is adopted. The control work is independently completed by the temperature control unit, and the control process is monitored in real time by the central control system.
The electric ash unloading ball valve has simple structure, small size, light weight, compact and reliable, low fluid resistance, and convenient disassembly and replacement of the sealing ring. and other advantages,
Ash ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Cemented carbide between the metal valve seat has a strong shear force, especially suitable for containing fiber, small solid particles and other media, is an important actuator in industrial automation control system.
