Abstract
The utility model discloses a quick-changing joint, comprising a pipe joint I (1) and a pipe joint II (5). The quick-changing joint is characterized in that the inner bore (4) of the pipe joint I (1) is provided with a groove (2) in which an O-shaped ring (3) is provided, one end of the pipe joint II (5) is provided with a sealing segment (6) which is tightly and movably matched with the inner bore (4) of the pipe joint I (1), and the two pipe joints are fixed with a screw nut (7). The utility model has novel structure and high sealing property, and is capable of being mounted and dismounted conveniently only by screwing off the screw nut by hands without spanner and other tools, and widely applicable for the on-site working of quick-changing joints in gas and liquid pipelines and metallurgy industry.
Description
Technical field
The utility model relates to a kind of joint, especially a kind of novel quick release coupling that is applied to gas, liquid pipeline.
Technical background
At present the quick release coupling that uses is a circle steel ball to be installed fix two sections pipes and connect in the endoporus that a pipe connects, this joint structure complexity, and accuracy of manufacturing and cost are higher.During tap changing, steel ball hole is stopped up by dust and greasy dirt easily under the environment that dust and greasy dirt are arranged, and makes the steel ball knot dead, is failure to actuate, during tap changing, must manually strike with hammer loosening, could tap changing, maintenance workload is big, makes not quick change of quick release coupling, oil leakage phenomenon occurs.Like this, the parts of joint are broken in past contact meeting, cause the damage of joint, can not reclaim, and can not reuse.
Technology contents
At the problem that existing quick release coupling exists, it is a kind of simple in structure, easy to use that the utility model provides, the novel quick release coupling that sealability is high.
The utility model connects I and pipe by pipe and connects II two-part and form, and is characterized in, pipe connects in the endoporus of I a groove, places " O " type circle in the groove; The end that pipe meets II has a seal section and pipe to connect the I endoporus closely movingly, fixes two sections pipes with nut again and connects.
The utility model is simple in structure, and processing cost is low, the sealability height, and 300 kilograms of pressure testing pressurizes were not leaked in 30 minutes.Because a seal section is arranged, the nut that do not need reinforcement seals, so dismounting is convenient, as long as turn on the handgrip nut, does not need with instrument dismounting such as wrench, is widely used in the operation field of gas, liquid pipeline and metallurgy industry quick release coupling.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1, pipe meets I 2, groove 3, " O " type circle 4, endoporus 5, pipe and connects II 6, seal section 7, nut
Specific embodiments
In the drawings, pipe connects in the endoporus (4) of I (1) a groove (2), place " O " type circle (3) in the groove (2), the end that pipe meets II (5) has a seal section (6) and pipe to connect I (1) endoporus (4) closely movingly, uses nut (7) fixed tube to meet I (1) again and pipe meets II (5)." O " type circle (3) is a seal ring, and seal section (6) is to reinforce sealing.
Claims (1)
1, a kind of novel quick release coupling connects I (1) and pipe by pipe and connects II (5) two-part and form, and it is characterized in that; Pipe connects in the endoporus (4) of I (1) a groove (2), places " O " type circle (3) in the groove (2); The end that pipe meets II (5) has endoporus (4) that a seal section (6) and pipe connect I (1) closely movingly, uses nut (7) fixed tube to meet I (1) again and pipe meets II (5).
