Description

Technical Field

[0001] The utility model belongs to the field of regulating baffles, and in particular relates to an regulating baffle for petrochemical industry. Background Art

[0002] Petrochemical industry, referred to as petrochemical industry, generally refers to the chemical industry that uses petroleum and natural gas as raw materials. It has a wide range and many products. Crude oil is cracked, reformed and separated to provide basic raw materials such as ethylene, propylene, butylene, butadiene, benzene, toluene, xylene, naphthalene, etc. Various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced from these basic raw materials.

[0003] Heating furnaces are widely used in petroleum, chemical, electric power, metallurgy and other industries. The regulating damper valve in the flue of the heating furnace plays a role in regulating the flow in the chimney or flue. By changing the opening degree of the valve plate blades, the oxygen content, negative pressure and flue gas flow in the furnace can be controlled to avoid the heating furnace from stalling.

[0004] The authorization publication number "CN219282445U" records "an electric baffle valve, including a valve body, flanges are provided on both sides of the valve body, through holes are provided on both ends of the valve body, a rotating rod is inserted in the through hole, baffles are provided on both sides of the rotating rod, a sealing iron ring is provided in the valve body, a first stuffing seat is provided at one end of the rotating rod passing through the valve body, a second stuffing seat is provided at the other end of the rotating rod passing through the valve body, a vertical plate is connected to one side of the first stuffing seat, a bracket is provided on one side of the vertical plate, a reducer is provided on the mounting plate, and a holder is provided on one side of the reducer. The rotor shaft of the holder drives the input shaft of the reducer to rotate to open and close the device. The reducer provides a large torque for the rotating rod. When the baffle is opened, it is not easy to move when it is subjected to high-pressure impact, and the flow rate when it is opened can be stably maintained. When closed, the baffle presses against the sealing iron ring, and acts together with the torque of the reducer to keep the baffle stable in the valve body, and acts together with the sealing iron ring to make the device not easy to leak".

[0005] The baffle of the above patent remains stable in the valve body, and works together with the sealing iron ring to make the device less likely to leak. However, the baffle in the above patent is a whole piece, which makes it more difficult to adjust. At the same time, when the smoke flow is too large, the resistance to the rotation of the baffle will increase. Utility Model Content
