Abstract

The invention discloses a clamp type reducing pipe connection device. The clamp type reducing pipe connection device comprises an outer casing and a seal device, wherein the outer casing comprises a first ring and a second ring, the first ring comprises a first semi-ring body and a second semi-ring body, and the second ring comprises a third semi-ring body and a fourth semi-ring body; the seal device comprises a reducing threaded frame, two threaded locking rings and at least two seal rings; the two threaded locking rings and the reducing threaded frame are connected through non-standard coarse threads; and two side surfaces of each seal ring abut against the inner end surface of the corresponding threaded locking ring and the seal surface of the reducing threaded frame respectively. The clamp type reducing pipe connection device is simple in structure, convenient to mount, good in seal performance and stable in firmness, can be mounted at different time in a split and segmented manner as required, and can connect pipe joints with different pipe diameters.

Description

technical field [0001] The invention relates to a pipeline conveying system, in particular to a clamp-type variable-diameter pipeline connection device. Background technique [0002] In large-scale compressed air or fluid pipeline systems, it is usually necessary to use larger diameter delivery pipelines in conjunction with small diameter delivery pipelines. Small pipe joints can be used for small diameter pipes, but this type of pipe joint is not suitable For pipelines with larger diameters, the connection strength cannot meet the requirements of pipelines with larger diameters. [0003] For the connection devices of larger diameter pipelines, the flange connection is generally used at present, which needs to be welded on site and then leak tested. If the weld has welding defects such as slag inclusion, it needs to be reworked, which has higher requirements for the on-site installation workers. The installation efficiency is low, and it is not easy to disassemble; in the p...
