Middle flange bolt connection slag discharge gate valve
Slag gate valve
Product usage
Slag gate valve is suitable for the working pressure of 1.6~6.4MPa, working temperature of 0~100℃ thermal power station water conservancy system and mortar discharge system pipeline of water conservancy project, cut off or connect the ash water mixture, slag water mixture in the pipeline.
Structural features
1.Middle flange bolt connection is adopted, and both ends of the branch pipe are flange connection or butt welding connection.
2.The opening and closing parts are forced sealed by semi-sealing pair, with excellent performance.
3.The sealing accessory material is wear-resistant ceramic or wear-resistant alloy, with strong wear resistance, strong wear resistance, durable erosion resistance, abrasion resistance, low friction and reliable sealing.
4.Valve body outlet channel junction is reasonable, no slag, flexible opening and closing, not stuck.
5.The valve stem has good corrosion resistance, abrasion resistance and wear resistance after tempering and surface nitriding treatment.
- Medium and large caliber rolling bearings, easy to open and close
