摘要： A gasket for preventing separation of interconnected pipes including a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes an inner surface having at least one tooth configured for engaging a spigot end of a pipe and an outer surface having an arm with a substantially flat portion arranged adjacent to a forward section of a retainer groove of the gasket, the substantially flat portion being configured for displacing the segment radially and axially upon insertion of the spigot end into a bell end of the other pipe thereby decreasing the spigot insertion force required to seat the spigot end within the bell end and the gasket.

摘要： A pipe gasket including a compressible body having a heel portion and a sealing portion and a plurality of metal segments at least partially embedded in the compressible body and circumferentially spaced therein. Each of the metal segments includes a compression arm extending within the sealing portion and radially outward and away from the heel portion, a rounded nose portion extending within the heel portion and an acutely pointed tooth extending radially inward from a segment portion located between the compression arm and the nose portion. The compression arm extends radially outward within the gasket from a point located proximal to the tip of the tooth to a point within the sealing portion that is distal to the tip of the tooth. This arrangement provides for leveraging of the radial forces created by the compression of the sealing portion between the spigot end and the bell end to increase the radially inward force applied by the tooth on the spigot end.

摘要翻译： 一种管垫，其包括具有跟部和密封部的可压缩主体，以及至少部分地嵌入在所述可压缩主体中并沿周向间隔开的多个金属段。 每个金属段包括在密封部分内径向向外并远离跟部部分延伸的压缩臂，在后跟部分内延伸的圆形鼻部部分和从位于压缩臂之间的段部分径向向内延伸的尖锐的齿 和鼻子部分。 压缩臂在垫圈内径向向外延伸，从位于牙齿尖端附近的点到密封部分内远离牙齿尖端的点。 这种布置提供了通过在插口端部和钟形端部之间的密封部分的压缩产生的径向力来增加由插齿端部上的齿施加的径向向内的力。

摘要： A gasket for preventing separation of interconnected pipes without damaging the pipes. The gasket includes a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes a row of exposed teeth configured for engaging a spigot end of a pipe and a trough configured for pivotably engaging a bead on a bell. The trough is further configured for shearing or deforming the bead and inhibiting over-pivoting of the segment about the bead when the pipes are partially withdrawn away from one another, for example, during over-pressurization of the pipes.

摘要翻译： 用于防止相互连接的管道分离而不损坏管道的垫圈。 垫圈包括具有部分地嵌入其中的多个金属段的可压缩主体。 每个金属段包括一排暴露的齿，其构造成用于接合管的插口端和构造成用于可枢转地接合在钟罩上的胎圈的槽。 槽还被构造成用于剪切或变形胎圈，并且当管道部分地彼此远离时，例如在管道的过度加压期间，阻止节段围绕胎圈的过度枢转。
