Abstract

A pressure-bearing and sealing pipeline for a pipe connector comprises a connector pipe and a spigot and socket pipe, wherein fastening nuts are sleeved on the spigot and socket pipe, outer threads matched with the fastening nuts are arranged on the connector pipe, a sealing part is arranged between the spigot and socket pipe and the connector pipe and is a conical sealing ring, and an internal groove matched with the conical sealing ring is arranged at the end of an inner hole of the connector pipe. The pressure-bearing and sealing pipeline for the pipe connector leads the connector pipe and the spigot and socket pipe to be integrally connected through the sealing part and the fastening nuts and is simple in structure. Two ends of the spigot and socket pipe are both in movable connection mode, so that the pressure-bearing and sealing pipeline is convenient to mount and demount, and mounting and maintenance are greatly facilitated. The sealing part is good in sealing performance so that the pressure-bearing and sealing pipeline is safe and reliable in use and long in service life, maintenance of the pressure-bearing and sealing pipeline is greatly reduced, and simultaneously the pressure-bearing and sealing pipeline can be widely used in liquid and gas delivery pipeline systems.

Description

A kind of pressure bearing and seal pipe joint pipe fitting
Technical field
The utility model relates to a kind of pipe joint coupling device, particularly a kind of pressure bearing and seal pipe joint pipe fitting.
Background technique
Complicated operation when pipe joint coupling device of the prior art is installed is not easy to dismounting simultaneously again, brings very big inconvenience for installation and repair demolition process, and poor sealing performance brings more seepage, increases the number of times of maintenance and repair again.Not only increase labor intensity of operating personnel, reduced working efficiency simultaneously.
Summary of the invention
The utility model technical problem to be solved is the deficiency to existing technology, and a kind of easy for installation, simple in structure, reliable sealing pressure bearing and seal pipe joint pipe fitting is provided.
The utility model technical problem to be solved is to realize through following technological scheme.The utility model is a kind of pressure bearing and seal pipe joint pipe fitting; Comprise adaptor tube and bell-and-spigot pipe; Be set with locking nut on the bell-and-spigot pipe, adaptor tube is provided with the outside thread that cooperates with locking nut, is characterized in: between bell-and-spigot pipe and adaptor tube, be provided with Sealing; Said Sealing is a conical seal ring, is provided with the internal groove that cooperates with conical seal ring in the interior bore ends of adaptor tube.
The utility model technical problem to be solved can also further realized, is provided with catch between the end of said Sealing and the locking nut through following technological scheme.
The utility model technical problem to be solved can also realize that further the stage casing of bell-and-spigot pipe is provided with bellows through following technological scheme.
The utility model technical problem to be solved can also further realize that the bell-and-spigot pipe outer tube wall is provided with the positioning mark line of sign bell-and-spigot pipe insertion depth through following technological scheme.
Compared with prior art, the utility model links together adaptor tube and bell-and-spigot pipe through Sealing and locking nut, and it is simple in structure; The bell-and-spigot pipe two ends are loose joint, and installation, convenient disassembly bring great convenience to installation and maintenance; Sealing property of sealing component is good, and is safe and reliable, long service life; Greatly reduced the maintenance of pipe fitting, simultaneously can extensive use and the pipeline system of liquid, gas in.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
A kind of pressure bearing and seal pipe joint pipe fitting; Comprise adaptor tube 1 and bell-and-spigot pipe 4; Be set with locking nut 2 on the bell-and-spigot pipe 4, adaptor tube 1 is provided with the outside thread that cooperates with locking nut 2, it is characterized in that: between bell-and-spigot pipe 4 and adaptor tube 1, be provided with Sealing 6; Said Sealing 6 is a conical seal ring, is provided with the internal groove that cooperates with conical seal ring in the interior bore ends of adaptor tube 1.
During use, locking nut 2 is enclosed within on the bell-and-spigot pipe 4, again Sealing 6 is installed on the bell-and-spigot pipe 4; Bell-and-spigot pipe 4 one ends are inserted in the adaptor tube 1; Make conical seal ring between bell-and-spigot pipe 4 and adaptor tube 1, twist locking nut 2, the end of locking nut 2 squeeze sealing members 6; The conical surface of Sealing 6 is wedged between the internal groove and bell-and-spigot pipe 4 of adaptor tube 1, plays seal action.The other end of bell-and-spigot pipe 4 is installed by same method, can use after installing.
Be provided with catch 5 between the end of said Sealing 6 and the locking nut 2.Catch 5 can play the effect of protection Sealing 6, prevents that Sealing 6 is impaired in disassembly process.
The stage casing of bell-and-spigot pipe 4 is provided with bellows 3, makes bell-and-spigot pipe 4 have telescopic resilience, has made things convenient for installation.
Bell-and-spigot pipe 4 outer tube walls are provided with the positioning mark line of sign bell-and-spigot pipe 4 insertion depths, can be used for identifying the position of judging that bell-and-spigot pipe 4 inserts in the adaptor tube 1.
