Title:
SLIDING CONNECTOR FOR BOILER
Document Type and Number:
WIPO Patent Application WO/2017/057814
Kind Code:
A1
Abstract:
The present invention relates to a sliding connector for a boiler. To this end, the sliding connector of the present invention comprises: a male connector coupled to a tube on one side such that the outside of the male connector makes contact with the tube; and a female connector coupled to a tube on an opposite side such that the outside of the female connector makes contact with the tube on the opposite side, wherein the male connector is slidably coupled to the female connector by a sliding insertion coupling part. Accordingly, the present invention can: prevent a change in the positions of the tubes despite a variation in the lengths of the tubes caused by thermal expansion or contraction generated in the process of starting and stopping a boiler and increasing and deceasing the output of the boiler; facilitate welding in the narrow space between the tubes; reduce the amount of used materials by minimizing welded joint portions; and prevent thermal deformation generated in the process of welding the tube and the male or female connector.
