Embodiment Construction
[0015] Such as figure 1 As shown, a ferrule-type pipe joint is composed of four parts: a lock nut 1, a ferrule, and a pipe joint body 4. The joints at both ends of the pipe joint body 4 are provided with threads that are threadedly connected with the lock nut 1. A ferrule is arranged between the joint at each end of the joint body 4 and the lock nut 1. The ferrule is composed of a sealing ring 3 and a compression ring 2. One end of the sealing ring 3 has a joint cone extending into each end of the pipe joint body 4. The other end of the sealing ring 3 has an annular end surface in sealing contact with the compression ring 2 of the cone body fitted in the body cavity.
[0016] The working method of the sleeve type pipe joint:
[0017] a. The basic structure is relatively simple, including the three basic parts of the joint body, the ferrule and the nut, which are stainless steel structures. The main part is the ferrule, which is a metal ring with a cutting edge at the front e...

The invention relates to the technical field of tube fittings and discloses a ferrule tube fitting, which is formed by lock nuts 1, cutting ferrules and a tube fitting body 4, wherein screw threads, which are in threaded connection with the lock nuts 1, are arranged on fittings on two ends of the tube fitting body 4, each cutting ferrule is arranged between the fitting on each end of the tube fitting body 4 and the corresponding lock nut 1, each cutting ferrule is formed by a sealing ring 3 and a clamp ring 2, a cone, which extends into a cone cavity of the fitting at each end of the tube fitting body 4 in a matching manner, is arranged on one end of each sealing ring 3, and an annular end face, which is in sealed contact with the clamp ring 2, is arranged on the other end of each sealing ring 3. The ferrule tube fitting has the advantages of good repeated assembly and disassembly performance, simple structure, reliable sealing property and convenience for use, and is particularly suitable for pipelines of hydraulic pneumatic equipment with oil and gas as mediums, and occasions with combustion danger, aloft work and frequent assembly and disassembly. The ferrule tube fitting is suitable for wide popularization and use.
Description
technical field [0001] The invention relates to the technical field of pipe joints, in particular to a ferrule type pipe joint. Background technique [0002] At present, the existing pipe joints are generally suitable for the threaded connection of pipes and pipes, and are used in the pipelines of hydraulic and pneumatic equipment with oil, gas, etc. as the medium. The pipelines are prone to impurities, which will affect the performance of the system. And it is not suitable for occasions where there is a danger of burning, high-altitude operations and frequent assembly and disassembly, and the performance of repeated assembly and disassembly. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a ferrule-type pipe joint. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts following technical scheme: [0005] A ferrule-type pipe joint is composed of a lock nut ...
