  • Patent number: 12287046
    Abstract: A valve seat, a plug valve, and a fracturing manifold are provided. The valve seat includes a sealing valve seat in an annular shape and a mounting valve seat in an annular shape. The sealing valve seat includes a sealing valve seat inner hole, and the mounting valve seat includes a mounting valve seat inner hole. The sealing valve seat is nested inside the mounting valve seat, and the sealing valve seat inner hole communicates with the mounting valve seat inner hole. In axial and radial directions of the sealing valve seat inner hole, or axial and radial directions of the mounting valve seat inner hole, an outer surface of the sealing valve seat abuts against an inner surface of the mounting valve seat.

  • Publication number: 20120010400
    Abstract: The invention discloses a pharmaceutical composition used in photodynamic therapy for cancer or precancerous lesions. The composition includes four isomers of zinc phthalocyanine. Furthermore, this invention also provides an industrial chromatography preparation process. The composition is synthesized by separating 10 cis-isomers from disulfonic acid diphthaloyl iminomethyl zinc phthalocyanine, and then separating among them 4 isomers with significant amphiphilic property. It is evident that the composition of the invention shows improved performance compared to compositions containing those 10 cis-isomers.
