AI Technical Summary

Technical Problem

During boiler peak shaving, existing technology requires shutdown to replace damaged flow meters, which affects production continuity. Furthermore, shutdowns when flow meters are installed on the main circuit can lead to production interruptions.

Method used

A sleeve structure was designed, including a baffle, a fixing rod, and a fixing seat. The flow meter can be replaced by rotating the baffle to seal and open. The flow meter is installed on the fixing seat and can slide inside the sleeve. The baffle and retaining ring provide sealing and limiting to prevent damage to the flow meter.

Benefits of technology

This allows for the replacement or inspection of flow meters without shutting down the boiler, improving maintenance efficiency, preventing flow meter damage due to compression, and ensuring continuous boiler operation.

Abstract

This utility model relates to the field of flow measurement technology, specifically to an annular independent three-out-of-two flow measurement device for boiler peak shaving. It includes a sleeve, a baffle plate installed in the middle of the sleeve, a fixing rod welded to the top of the baffle plate, the top of the fixing rod extending through the sleeve to the top of the sleeve, flanges welded to both ends of the sleeve, a fixing plate installed on the flange at one end of the sleeve, a through hole on the fixing plate, a sleeve welded to the side of the fixing plate outside the through hole, a fixing seat sliding along the sleeve installed inside the sleeve, an installation hole in the middle of the fixing seat, and a flow meter installed on the side of the fixing seat away from the sleeve. The detection end of the flow meter passes through the sleeve and the sleeve. This utility model, with its sleeve and baffle plate, allows for easy replacement of the flow meter. When the flow meter needs to be replaced, the baffle plate can be rotated to open and seal it, allowing the damaged flow meter to be replaced. After replacement, the baffle plate can be rotated to open and the flow meter pushed in for installation, without requiring the machine to be stopped.
