Abstract
The invention discloses a quick pipeline connecting method and a joint using the same. The joint comprises a joint body, wherein a clamping ring, a conical base and an O-shaped sealing ring are sequentially arranged inside the joint body along the pipeline insertion direction; when the pipeline is inserted into the joint, a flange arranged on the clamping ring is deflected; and when the pipeline expands under increased pressure after the introduction of a liquid, the O-shaped sealing ring expands axially under the action of pressure, and the clamping ring is driven to move along a direction opposite to the pipeline insertion direction by pushing the conical base to clamp the pipeline. The invention also discloses a quick pipeline joint adopting the quick connecting method. The joint has the advantages of capabilities of making an elastic pipe body (such as a PEX pipe body) easier to insert and ensuring that the elastic pipe body does not loosen easily after being inserted and expanded due to increased pressure caused by the introduction of the liquid, high air tightness and connecting reliability.
Description
technical field [0001] The invention relates to a method for connecting pipes, in particular to a method for quickly connecting fluid pipes such as water pipes and a joint using the method. Background technique [0002] Pipelines are essential infrastructure for industry. The pipeline connection device is an indispensable means of connection. [0003] At present, the well-known pipeline connections mainly include threaded connections and hot-melt connections (PP-R and PE pipes, etc.). The threaded connection is to use the joint and the pipe and its own internal and external threads for screw connection, and use the polytetrafluoroethylene raw material tape as the sealing packing to seal; the hot-melt connection is to use electric heating to heat the connecting part of the pipe and the joint to a molten state , and then pressed against each other, so that the homogeneous materials on the contact surface melt into each other to connect and seal them. The above two connectio...
