摘要
PURPOSE: A split valve seat and a rising stem ball valve using the same are provided to improve sealing performance because a contact part between an inner seat and an outer seat is elastically deformed to be closely attached when a ball is tilted.;CONSTITUTION: A split valve seat(100) comprises an inner seat(110) and an outer seat(120). The inner seat comprises a ring shaped inner seat body(111) and an inner protrusion piece(112) protruded from one side of the inner seat body. The outer seat comprises an outer seat body(121) and an outer protrusion piece(122). The diameter of the outer seat body is larger than the diameter of the inner seat body. The outer protrusion piece is protruded from one side of the outer seat body. The inner and outer protrusion pieces face each other at a separated state, and are closely attached each other because both are elastically deformed when a ball is connected.;COPYRIGHT KIPO 2013
