Description
Technical Field
The utility model relates to a quick-operation joint technical field especially relates to a quick-operation joint for fluid pipeline.
Background
The joint is a connecting tool between pipelines, is a detachable connecting point between an element and the pipelines, plays an indispensable important role in pipe fittings, and is one of two main components of a hydraulic pipeline. The requirements for pipe joints are different according to different fluids in the pipeline, and therefore, various pipe joints are manufactured; for example, a pipe joint is proposed, which comprises a joint and a gland, wherein the gland is detachably connected with the joint through a thread, and the end head part of the joint is provided with a snap ring seat; the inner end of the snap ring seat extends into the connector, a sealing ring is arranged to abut against the snap ring seat, an elastic snap ring is arranged on the outer end face of the snap ring seat, and the elastic snap ring comprises a ring body and teeth arranged along the inner ring of the ring body; the outer end of the elastic snap ring is provided with a pushing piece with a funnel-shaped inner wall, and two ends of the pushing piece are respectively abutted against the elastic snap ring and the lug boss. When the pipe joint is used, the gland is screwed, the lug boss on the gland presses the pushing piece, and the pushing piece presses the elastic clamping ring to enable the teeth to bite the pipe, so that the pipe joint is fixed on the pipe.
However, it is known that the pipe joint, in which the pipe is made of a different material and the hardness of the pipe is different due to the different material, can tightly bite the pipe and achieve a good fixing effect when the hardness of the pipe is less than or equal to that of the teeth of the elastic snap ring; however, when the hardness of the pipe is greater than that of the teeth on the elastic snap ring, at this time, the teeth are soft relative to the pipe, and cannot firmly bite the pipe, and because the pressure of the fluid between the pipe and the pipeline is relatively large, the pipe joint easily enables the pipe to withdraw from the pipe joint, so that the interface is burst open, the fluid leaks, not only resources are wasted, and inconvenience is brought to the life of people, and more importantly, when the fluid is a toxic, harmful, flammable or explosive fluid, the normal life of people can be seriously affected, and even the life health and property safety of people are harmed.
