Title:
GASKET FOR SNAP TAP WITH SADDLE
Document Type and Number:
Japanese Patent JP3694184
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely maintain the water cut-off ability of a gasket long even if it is used for a pipe for soft water.
SOLUTION: This gasket 10 is secured in the gasket containing section 28 of a saddle 16, one of components of a snap tap 14 with saddle. When the snap tap 14 with saddle is fixed to the outer face of a pipe 12, a lip section 44 is pressed against the outer face of the pipe 12, closing a groove 42. Since even in this case, each protruded section 46 formed on the inner face of the groove 42 functions as a spacer, space is always secured in the groove 42. Since a plurality of the protruded section 46 are spacedly formed, an opening port is secured between protruded sections 46. Therefore, during water passing, water enters the deep section of the groove 42 through opening ports, water pressure acts on the top face of the lip section 44. Since through this constitution, force to press the lip section 44 against the outer face of the pipe 12 can be compensated by making water pressure work on the top face of the lip section 44, surface pressure can be reduced by setting the compression margin of the gasket 10 small. Therefore, the deformation of the pipe 12 with the passage of time caused by the restoring force of the gasket 120 can be prevented, and water cut-off ability can be maintained long.
