Compound rubber sealing ring of ultra-large water supply spigot and socket pipe

Abstract

The invention discloses a compound rubber sealing ring of an ultra-large water supply spigot and socket pipe. The compound rubber sealing ring comprises anti-falling annular grooves formed close to the end in a socket of the spigot and socket pipe, wherein an anti-falling rubber ring is arranged in each anti-falling annular groove; a cavity annular groove is formed in each anti-falling rubber ringin an annular direction; a plurality of fixing tongues are arranged on each anti-falling rubber ring; the plurality of fixing tongues are sleeved with arc-shaped anti-falling strips; an anti-fallingconvex ring is integrally arranged on the outer wall of the spigot of the spigot and socket pipe; a rubber ring groove is formed in one side of each anti-falling annular groove in the socket; and a rubber sealing ring is arranged in each rubber ring groove. The compound rubber sealing ring of the ultra-large water supply spigot and socket pipe is convenient to mount, good in connecting effect andnot easy to slip; the construction period is shortened; the construction cost is reduced; and the sealing effect is good.

Description

technical field [0001] The present disclosure generally relates to the technical field of rubber fittings, and in particular relates to a composite rubber sealing ring for a super-large water supply bearing intubation pipe. Background technique [0002] A large number of socket pipes are used in the urban water supply network. Some of the main pipes have very large diameters. The socket and the socket of the socket pipes are sealed waterproofly by rubber sealing rings. The sealing effect of ordinary rubber sealing rings is average. Moreover, in order to prevent slipping of the joints of the socket pipes, complicated reinforcement treatment is required, the construction time for pipe network laying is long, and the construction cost is relatively high. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is expected to provide a composite rubber sealing ring for super large water supply socket intubation pipes that i...
