Abstract

The invention provides a high pressure resistant leakage-proof metal sealing clamp hoop locking type large diameter pipeline connecting device, belongs to the technical field of large diameter fluid-conveying pipeline connecting devices, and aims at solving the problems that an existing large diameter pipeline connecting equipment rubber sealing device is not resistant to high temperature, short in service life, unstable in sealing performance, poor in safety, high in maintenance cost, small in bearing pressure, harsh in installation requirement and not suitable for some occasions such as spacial gas and liquid seal. The high pressure resistant leakage-proof metal sealing clamp hoop locking type large diameter pipeline connecting device comprises a clamp hoop, bolts, two limiting rings and a sealing device composed of a sealing ring, the sealing ring is arranged in the middle of the sealing device, the limiting rings are arranged at the two ends of the sealing ring, and the sealing device is arranged in a groove in the middle of an inner cavity of the clamp hoop. The high pressure resistant leakage-proof metal sealing clamp hoop locking type large diameter pipeline connecting device has the advantages of being good in sealing effect, stable in sealing performance, long in service life, convenient to install and maintain, capable of being applied to the harsh environments such as high temperature, high pressure and special medium and strong in applicability for pipelines with different materials.

Description

technical field [0001] The invention belongs to the technical field of connecting devices for large-diameter fluid delivery pipelines, and in particular relates to a high-pressure-resistant and anti-leakage metal sealing hoop locking type large-diameter pipeline connecting device. Background technique [0002] In the existing special fluid transportation technology, the connection technology of large-diameter pipelines, whether it is high-pressure pipeline fluid transportation, medium-pressure pipeline fluid transportation, or low-pressure pipeline fluid transportation, the traditional welding method or flange connection method used in the old days will be damaged during welding. The outer and inner anti-corrosion layers of steel pipes require secondary anti-corrosion work, flaw detection is required to prevent false welds during the welding process, slag inclusions in the weld seam, and rework is required when welding defects occur, etc., which have high requirements for on-...
