Problems solved by technology

[0002] The lower valve head of the existing crushed coal pressurized gasifier, the valve stem, the valve head and the ash cover are welded and fixed in one piece, and the positional relationship between the three parts cannot be adjusted relative to each other. When the valve head falls and is in sealing contact with the valve seat, If the valve head or the valve stem is slightly deviated, it will cause the valve head and the valve seat to fail to fit and seal. At the same time, the heavy pressure of the lower valve head will damage the contact surface of the lower valve seat, which will cause the lower valve seat to be easily damaged, which will greatly affect the The working effect and working efficiency of the crushed coal pressurized gasifier
