Socket joint type pipe head

Abstract

This invention relates to a spigot and faucet pipe connector applying metal ring for lock, rubber liner sealing and screw bolt to lock at the side which can adjust freely it terms of the assembly conditions round the pipe center by 360 deg. with very compact structure, conveneint for maintenance and operation.

Description

technical field [0001] The present invention relates to machinery, in particular to a socket-type pipe joint, especially one that adopts metal ring locking, rubber bushing sealing, side bolt locking, compact structure, minimal installation work space, and random installation work angle. Socket fittings. Background technique [0002] With the advancement of science and technology, the application of pipeline systems is wider and the connection requirements are more stringent, especially on ships, where the pipelines are dense and require continuous sealing to prevent oil leakage, water leakage, and air leakage, and to control weight and size. Realize vibration reduction and noise reduction, easy installation and maintenance; traditional pipeline connection methods such as threaded connection, socket connection, welding and flange connection, etc., have their own characteristics, but there are also many disadvantages; End sleeve wire, long construction preparation time, requi...

Problems solved by technology

[0002] With the advancement of science and technology, the application of pipeline systems is wider and the connection requirements are more stringent, especially on ships, where the pipelines are dense and require continuous sealing to prevent oil leakage, water leakage, and air leakage, and to control weight and size. Realize vibration reduction and noise reduction, easy installation and maintenance; traditional pipeline connection methods such as threaded connection, socket connection, welding and flange connection, etc., have their own characteristics, but there are also many disadvantages; End sleeve wire, long construction preparation time, requires strict installation accuracy, and the threaded connection in use has poor sealing performance, is easy to rust and leak, and is not widely used. It is generally only used on small-diameter domestic water pipelines; socket connection method The connected pipe ends need to be processed in advance, generally suitable for sewage pipelines made of cast iron and with low working conditions; the welding connection method requires high weldability of the pipes, and residual stress is easily generated during the welding process. It forms a rigid connection and has low compensation for temperature difference. On-site welding and testing are limited by the working space. It is generally used for pipelines with high sealing requirements, high temperature and pressure; the flange connection method requires prefabricated flanges at the pipe ends. , the precision of the butt joint assembly is high, the flange itself and the large space occupied by the wrench must be reserved for work, and the distance between the pipes and the space occupied by the pipe system have to be increased. It is not easy to keep the seal in the environment, which may lead to air leakage, oil leakage and water leakage. Although this flange connection method is widely used at present, it is also very troublesome for the above problems; for this reason, many people are exploring new technologies. , to improve the shortcomings of the above-mentioned pipeline connections
