FIELD: machine building. ^ SUBSTANCE: pipelines joint comprises two cases with interacting valves to be jointed together. One of said valves is fixed relative to said case and is embraced by moving spring-loaded sleeve. Said split sleeve consists of outer part and inner part coaxial therewith. Note here that inner structural part is made from metal while outer part is made from material that features recoverable strain in wide temperature range, resistant to aggressive media, and with low friction factor. ^ EFFECT: ease of jointing. ^ 2 dwg |
