Abstract
The present invention may be basically described as a gasket for converting a standard mechanical joint into a restrained mechanical joint without the need for altered configuration of the bell, spigot, or gland of the joint, and without the need for additional fittings or devices. in the practice of the present invention, a standard mechanical joint's bell and gland configuration can be employed to connect a spigot end of one pipe length to the bell end of another pipe length in a restrained relationship, with the restraint based on forces superior to rubber-to-pipe friction. In more particular discussion of the embodiments taught, the invention includes forming the gasket to fit within the bell in such a manner that a void, or gutter, exists during rest, into which void the gasket compresses, which in turn influences the rotational motion of the segment. In this manner, the configuration of the gasket influences the timing and extent of rotation throughout the process of securing the gland to the bell.
Claims (11)
1. A method of assembling a restrained mechanical joint, comprising the steps of:
a) urging a portion of a gasket into a sealing relationship between a bell and a spigot;
b) subsequent to step (a), compressing the gasket with a gland to at least partially collapse a gutter in the gasket; and c) subsequent to beginning step (b), rotating a locking segment into resistive contact between the bell and the spigot.
a) urging a portion of a gasket into a sealing relationship between a bell and a spigot;
b) subsequent to step (a), compressing the gasket with a gland to at least partially collapse a gutter in the gasket; and c) subsequent to beginning step (b), rotating a locking segment into resistive contact between the bell and the spigot.
2. The method of assembling as in Claim 1, wherein the gutter is a void below a radially outer surface of the gasket.
3. The method of assembling as in Claim 1, wherein the gutter is an annular depression in a radially outer surface of the gasket.
4. A restraining gasket for use in a stuffing box assembly and comprising a locking member and adapted to change its center of pressure as it deforms in response to compression by a gland, in such a manner that during deformation of the gasket, translation and rotation of the locking member occurs.
5. The gasket as in Claim 4, wherein the change in center of pressure is influenced by a collapsible void or gutter.
6. The gasket as in Claim 4, comprising a locking segment having at least one tooth disposed radially inwardly.
7. The gasket as in Claim 4, wherein said locking segment comprises a plurality of teeth disposed radially inwardly and an area between at least two of said teeth is devoid of gasket material.
8. A combination of a restraining gasket together with a gland for use in a stuffing box assembly when connecting a male pipe portion to a female pipe portion, said restraining gasket comprising:
a compressible body having a spigot-facing surface, a radially outward surface, a gland-facing surface, and a gutter; and a locking member, said member having a tooth portion and an embedded body portion, wherein at least a portion of the tooth portion is positioned to engage the male pipe portion, wherein the gutter is positioned at or radially inward of the radially outward surface between a radially outermost area of the locking member and a surface of the gasket that contacts the female pipe portion when the gland is connected to the female pipe portion with the gasket therein between.
a compressible body having a spigot-facing surface, a radially outward surface, a gland-facing surface, and a gutter; and a locking member, said member having a tooth portion and an embedded body portion, wherein at least a portion of the tooth portion is positioned to engage the male pipe portion, wherein the gutter is positioned at or radially inward of the radially outward surface between a radially outermost area of the locking member and a surface of the gasket that contacts the female pipe portion when the gland is connected to the female pipe portion with the gasket therein between.
9. The combination of a restraining gasket together with a gland as in Claim 8, wherein the gutter forms a portion of the exterior contour of the radially outer surface.
10. The combination of a restraining gasket together with a gland as in Claim 9, wherein the radially outer surface includes a compression seat surface and a distortion control surface, said distortion control surface leading into the gutter and disposed at an angle of between 5 and 20 degrees with reference to a central axis of the gasket.
11. The combination of a restraining gasket together with a gland as in Claim 8, wherein the gutter is a void below the radially outer surface.
