Abstract

The invention discloses a pipe joint device. The pipe joint device comprises a pipe connection body, sealing rings, a locking compression sleeve and a gland. A pipe connection body thread is arranged at one end of the pipe connection body. A sealing face is arranged inside the pipe connection body. The sealing rings are placed on the sealing face inside the pipe connection body. The other end face of each sealing ring abuts against the inner end face of the locking compression sleeve. The locking compression sleeve comprises an annular sleeve body, annular steps which are arranged at the periphery of the annular sleeve body in a sleeving manner and claw teeth. The inner end of the locking compression sleeve is inserted into the pipe connection body, and the outer end of the locking compression sleeve is provided with an annular body with the taper degree. The claw teeth are arranged on the annular body. The inner side of each claw tooth is provided with a claw tooth thread. A gland thread is arranged at the inner side of the gland, and the gland is connected with the pipe connection body through the thread of the gland and the thread of the pipe connection body. According to the pipe joint device, the structure of an existing pipe joint is simplified, and the sealing effect is improved; and the pipe joint device has the beneficial effects of being simple in structure, convenient to implement, firm in connection, good in sealing effect and long in service life.

Description

technical field [0001] The invention relates to a pipeline connection device. Background technique [0002] The small pipe joints currently used generally adopt threaded connection, and can be quickly installed through multiple components such as snap rings, sealing rings, elastic snap rings, pushers, glands, etc. The sealing effect has problems such as complex structure and cumbersome installation, and its sealing effect and firmness are not ideal.
