一.Product Introduction
The PZ941H electric slag discharge gate valve is suitable for the slurry discharge system pipelines of thermal power station water conservancy systems and water conservancy projects with a working pressure of 1.6 to 6.4MPa and a working temperature of 0 to 100℃, to cut off or connect the ash-water mixture and slag-water mixture in the pipeline
二.Product Features
- Middle flange bolt connection is adopted, and the two ends of the branch pipe are flange connection or butt welding connection.
- The opening and closing parts adopt a semi-sealed pair for forced sealing, which has excellent performance.
- The sealing pair material is wear-resistant ceramic or wear-resistant alloy, which has strong wear resistance, is durable against erosion and scratches, has low friction, and ensures reliable sealing.
- The flow channel structure at the valve body outlet is reasonable, with no slag accumulation, flexible opening and closing, and no jamming.
- The valve stem has undergone quenching and tempering as well as surface nitriding treatment, which endowing it with excellent corrosion resistance, scratch resistance and wear resistance.
- Rolling bearings are set for medium and large diameters, making opening and closing easy.
