Abstract
The utility model discloses a kind of Collapsible pipeline connecting device, it comprises adpting flange I, adpting flange II, adpting flange I and adpting flange II medium transport pipeline in mating connection and adapter, described adapter is set in outside internal duct, it also comprises hold down gag, described hold down gag is sleeved in internal duct, is installed between adpting flange I and adpting flange II, hold down gag place is also provided with flexible graphite packing, and described flexible graphite packing is packed between internal duct and adpting flange.The Collapsible pipeline connecting device that the utility model provides, well solve the connectivity problem between the larger pipeline of two temperature, pressure difference, decrease because of the temperature difference, pressure difference is excessive and the problem that the joint stress caused is excessive, and, convenient disassembly, structure is simple, with low cost.
Description
Technical field
The utility model belongs to interconnection technique field, is specifically related to a kind of pipeline connecting device.
Background technique
Usually need in the industries such as electric power, chemical industry, oil, medicine to adopt different media to heat or the internals of cooling equipment, and the delivery line of these media often with need to be heated or the internal duct pressure of cooled equipment, temperature difference larger, direct connection can cause localized stress larger, cause joint ftracture and lost efficacy, severe one directly causes equipment to burst.
Model utility content
In order to solve the problem, the purpose of this utility model is, there is provided a kind of detachable pipeline connecting device, the internal duct of medium transport pipeline and equipment, without the need to direct connection, reduces because of the temperature difference, pressure difference is excessive and the problem that the joint stress caused is excessive.
Described Collapsible pipeline connecting device, it comprises adpting flange I, adpting flange II, adpting flange I and adpting flange II medium transport pipeline in mating connection and adapter, described adapter is set in outside internal duct, it also comprises hold down gag, described hold down gag is metal pressure ring, is sleeved in internal duct, is installed between adpting flange I and adpting flange II, hold down gag place is also provided with flexible graphite packing, and described flexible graphite packing is packed between internal duct and adpting flange.Adopt Flange joint, convenient disassembly, is convenient to overhaul of the equipments; The position that the good fixing internal pipeline of energy and flange are set of hold down gag, the destruction that simultaneously can also effectively prevent vibration equipment from bringing; Flexible graphite packing well solves the sealing problem between pipeline; Medium transport pipeline is not directly connected with internal duct, avoids the joint stress problem of cracking comparatively greatly.
The detachable pipeline connecting device that the utility model provides, its beneficial effect is, well solve the connectivity problem between the larger pipeline of two temperature, pressure difference, decrease because of the temperature difference, pressure difference is excessive and the problem that the joint stress caused is excessive, and, convenient disassembly, structure is simple, with low cost.
