Double-ferrule type pipe connector for nuclear power unit

Abstract

The invention discloses a double-ferrule type pipe connector for a nuclear power unit. A connecting block, a clamping connection unit and fastening units are included. According to the connecting block, the front side and the rear side of the connecting block are provided with the fastening units. According to the clamping connection unit, the clamping connection unit comprises ferrules, inner threads, outer threads and connecting pipes, the two connecting pipes are arranged, the inner side ends are connected with the left end and the right end of the connecting block correspondingly, the inner threads are arranged on the surfaces of the outer side ends of the two connecting pipes, the two ferrules are arranged, the inner threads are arranged in the inner side ends, the inner side ends ofthe ferrules are matched with the outer side ends of the connecting pipes, the diameter of the interiors of the ferrules is larger than the diameter of the exteriors of the connecting pipes, and the inner threads are matched with the outer threads. Pipe bodies are further included, and the two pipe bodies are arranged and matched with the interiors of the outer side ends of the two connecting pipes correspondingly. The double-ferrule type pipe connector for the nuclear power unit is convenient to use, firm in fixing, good in seal effect and long in service life.

Description

technical field

[0001] The invention relates to the technical field of pipe joints, in particular to a double ferrule type pipe joint for nuclear power units. Background technique

[0002] At present, the widely used metal pipe connection methods include threaded, welded, flared, ferrule and other pipe joints, and different connection forms and joints are used according to different working conditions and conditions. However, in today's industrialization and intensive development, due to the ferrule-type pipe joints have the advantages of good connection and sealing, convenient installation and operation, etc., its application range and number of uses are constantly increasing. Most of the pipe joints are clamped in a single way, which will cause the vibration generated by the equipment to affect the connection. After a long time, the connection will not be firm, and problems such as leakage will occur at the same time. Too smooth inside will cause the tube to slip inside t...
