Zusammenfassung:	The utility model relates to a modified PEEK valve seat, and relates to the technical field of valve seats. The valve seat comprises a valve seat body, and the valve seat body is of an annular structure made of PEEK materials. A common gasket is replaced by the fireproof gasket made of the PEEK material, and compared with common materials, the fireproof gasket made of the PEEK material can meet the characteristic requirements of sealing, high temperature resistance and long service life more easily, and is suitable for being used in environments with high requirements for high temperature and fireproof grades. The PEEK material is formed by mould pressing of graphite, glass fibers, carbon fibers and PTFE, has the advantages of being not prone to deformation, good in abrasion resistance, resistant to high temperature and the like, and can meet the characteristic requirements of sealing, high temperature resistance and long service life more easily compared with common materials. 本申请涉及一种改性PEEK阀座，涉及阀座技术领域。其包括阀座本
