AI Technical Summary

Technical Problem

The existing stainless steel oil exhaust pipes have oil seepage problems due to rust, corrosion and aging of the flange connections, and the simple pipe components of the flue cause poor exhaust effect, which poses a fire safety hazard.

Method used

The pipe unit adopts a circular tube structure, with a support boss, a flow guide ring plate and a socket at the end. Combined with a detachable flow-guided fire-proof check valve, the flow guides the gas flowing in the open valve disc, improves the exhaust effect and reduces the installation difficulty.

Benefits of technology

Under the same ventilation volume, the cross-sectional size of the pipeline unit is reduced, the strength and sealing of the connection structure are improved, the installation difficulty is reduced, and good exhaust effect is achieved, avoiding oil seepage and fire safety hazards.

Abstract

The utility model provides a pipeline unit for an oil smoke exhaust pipeline system and the oil smoke exhaust pipeline system. The pipeline unit is of a circular pipe structure with a circular cross section. A bearing boss is arranged at one end of the pipeline unit, the bearing boss is of an annular structure, and a flow guide annular plate is arranged in the axis direction of the pipeline unit and extends outwards relative to the bearing boss; the other end of the pipeline unit is provided with a bell and spigot used for being matched with the flow guide ring plate in an inserted mode, and the outer edge of the bell and spigot is provided with a butt joint wing plate capable of abutting against the side face of the bearing boss; the flow guide type fireproof check valves are arranged corresponding to all floors and detachably connected with the side wall of the pipeline unit, valve bodies of the flow guide type fireproof check valves are located in the pipeline unit, and air inlets of the flow guide type fireproof check valves are communicated with the pipeline unit. Gas flowing in after the valve clack is opened is guided to be discharged to the pipeline unit, and the exhaust effect is good.
