Working principle of forged steel globe valve:
The middle chamber of the forged steel socket welding globe valve adopts a self tightening sealing structure, which has good sealing performance. The two ends of the branch pipe are welded structures. The sealing surfaces of the valve disc and valve seat are made of Stellite cobalt based hard alloy overlay welding, which is wear-resistant, high-temperature resistant, and has good scratch resistance. The valve stem has undergone quenching and surface nitriding treatment. The depth of the valve cover packing box is reasonable, and the packing with corrosion inhibitor is reliable for sealing. The valve has an inverted sealing structure to ensure that there is no leakage from the valve stem during valve opening and operation. Widely used in fields such as petroleum, chemical, natural gas, metallurgy, chemical fiber, papermaking, urban construction, etc.
Features of forged steel globe valves:
1. The product design and manufacturing are in accordance with the ANSIB16.34 and E101 standards, and can be equipped with imported equipment for use.
2. The inner chamber of the valve adopts a pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance.
3. The sealing surfaces of the valve disc and valve seat are made of Stellite cobalt based hard alloy overlay welding.
4. The depth of the valve cover packing box is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable, and the switch is stable.
5. The valve has an upper sealing structure to ensure that there is no leakage from the valve stem during valve opening and operation.
