Novel clamping jaw type mechanical connector seal

Abstract

A new jaw type mechanical connector seal, consisting of a pressure ring, etc. Under the action of the interference, the four sealing rings inside the matrix shrink radially and contact the outer surface of the oil pipeline, and with the increase of the interference, the contact static pressure between the two contact surfaces gradually increases Large; in order to make the sealing pressure ring produce a reliable sealing performance under high pressure, according to the sealing characteristics of the rubber sealing ring, the rubber sealing surface is soft and has a large amount of elastic deformation as a whole; set the loading tool on one end of the joint, so that The claw of the loading tool falls into the slot in the middle of the base body of the joint, and the other end surface of the loading tool is attached to the outer end surface of the pressure ring, and high-pressure oil is passed into the loading tool; a limiter is set on the valve stem; the threaded section Under the effect of interference, the thread is embedded in the pipe, and tightly hugged with the pipe to withstand various external loads.

Description

Technical field [0001] The invention relates to a novel claw-type mechanical connector seal, which is especially used in petroleum development. Background technique [0002] Petroleum is the source of power for national economic development and the reliable basis for human survival. With the integration of the global economy, the dependence on energy is increasing rapidly, especially a large amount of oil is needed. Petroleum is a non-renewable resource, and the storage of petroleum on the earth is limited. In recent years, due to the excessive exploitation of petroleum resources on land, some areas have been short of resources. Offshore oil extraction technology is more difficult than on-shore oil extraction technology. On-site workers can work on site, and the construction is more convenient; the seabed environment is more complicated, and the water pressure gradually increases with the increase of water depth, which increases the difficulty of maintenance; With the incr...
