Title:
中心脚部を後退させることを伴うシールを有する結合具
Document Type and Number:
Japanese Patent JP6951475
Kind Code:
B2
Abstract:
A coupling for joining pipe elements has segments surrounding a central space with cusps which engage lobes of a seal to maintain the segments in spaced apart relation in a preassembled state. While the coupling is in the preassembled state the pipe elements may be inserted into the central space without disassembling the coupling, and portions of the seal adjacent to attachment members on the segments seat within a channel defined by the segments between the cusps. When the seal is compressed between the segments and the pipe elements to form a joint the seal deforms so as to withdraw a center leg of the seal from the flow path defined within the pipe elements.
