Abstract
The invention relates to a pipe joint, in particular to a pipe joint suitable for a pipeline system for transporting water and steam. The pipe joint comprises a joint and a pipeline and is characterized in that the joint is in a pipe shape, and the inner walls of both end parts of the joint are provided with a sealing groove; the pipeline is inserted in the joint, and the inner end of the pipeline passes through the sealing grooves; the sealing grooves are internally provided with sealing rings; the joints at both sides of the sealing grooves are inwards extruded to form a first annular pressing groove and a second annular pressing groove so as to seal and fasten the joints and the pipeline together. The pipe joint has the advantages of convenient construction, high use safety property, no stress corrosion, good sealing property, and the like.
Description
Technical field
The present invention relates to a kind of pipe joint, especially a kind of dual-extrusion quick joint that is applicable to the pipe-line system of transporting water and vapour.
Background technique
Along with development of science and technology, the application of pipe-line system is wider.Existing pipeline connecting mode generally has clamp band type connection, FERRULETYPE connection, bayonet joint, welding type to connect and be connected or the like with flange-type.The clamp band type Placement, the pipe end that connects in advance groove processing form two kinds, a kind of is that thick-wall tube is machined, and must process in producer, another kind is the extrusion modling groove, and there is stress in processing connecting tube later, and has the hidden danger of stress corrosion; FERRULETYPE connects, and needs certain installing space, connects tube wall thickness and also needs the thickness that reaches certain; The bayonet joint mode is connecting also machine shaping in advance of pipe end; Welding type connects, and must weld at the scene that (be commonly called as in project installation and get angry, getting angry exists potential safety hazard, and inconvenience is installed, so reality is to avoid in installing as far as possible.), the weldability of tubing is required height, welding process can produce residual stress, and postwelding forms and is rigidly connected, and the tubing flexible compensation performance that temperature variation is produced is low, and is all restricted to the field welding construction space; Flange-type connects, require high to the butt joint assembly precision, and to on-the-spot pipe end welding requirements height, when connecting, flange need reserve spanner, space shared during work is bigger, have to strengthen pipeline spacing and pipeline and take up space, this connection belongs to and is rigidly connected, and is difficult for keeping sealing under the working environment of long-term vibration.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of easy construction, usage safety performance height are provided, do not have the dual-extrusion quick joint of stress corrosion, good seal performance.
According to technological scheme provided by the invention, comprise joint and pipeline, it is characterized in that: described joint all is provided with seal groove at two end inwalls of joint in a tubular form, and described pipeline inserts in the described joint, and described seal groove is passed in the inner of described pipeline; Seal ring is set in seal groove; Extruding forms first annular pressing groove and second annular pressing groove in joint on the joint of seal groove both sides, and joint and seal for pipe joints are tightened together.
Position corresponding to first annular pressing groove and second annular pressing groove on pipeline forms pressing groove respectively.Described pipeline inserts length in the joint less than half of described length of said joint.
The present invention has easy construction, usage safety performance height, does not have advantages such as stress corrosion and good seal performance.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: described dual-extrusion quick joint, comprise joint 3 and pipeline 2, described joint 3 all is provided with seal groove 5 at two end inwalls of joint 3 in a tubular form, and described pipeline 2 inserts in the described joint 3, and described seal groove 5 is passed in the inner of described pipeline 2; Seal ring 6 is set, to improve the sealability of 2 in joint 3 and pipeline in seal groove 5; Extruding forms first annular pressing groove 4 and second annular pressing groove 7 in joint 3 on the joint 3 of seal groove 5 both sides, and joint 3 and pipeline 2 sealings are tightened together.
Position corresponding to first annular pressing groove 4 and second annular pressing groove 7 on pipeline 2 forms the pressing groove that forms because of extruding respectively, to improve the join strength of 2 in joint 3 and pipeline.
Described pipeline 2 inserts length in the joints 3 less than half of the length of described joint 3, so that connect another root pipeline at the other end of joint 3.
