The utility model discloses a pipeline and terminal joint screw with the torsion mode, can avoid machining tolerance clearance risk.
Description
Technical Field
The utility model relates to the technical field of pipelines, especially, relate to a pipeline seal structure suitable for few oily equipment.
Background
The pipeline seal structure who adopts at present is the sealed structure of twolip cutting ferrule, and this structure has the clearance of pipeline and twolip cutting ferrule, screws up the number of turns and requires the problem, and the effect that will reach complete sealing still has the risk, and concrete defect is as follows:
(1) the purchased outer circle of the pipeline has tolerance which is difficult to be completely unified, and a double-edge cutting sleeve needs to be selected and matched;
(2) the production surface of the pipeline has pull marks which are not easy to be found completely;
(3) when the double-edge cutting sleeve sealing type is required to be screwed by 1-1/4 circles, the sealing aspect cannot be completely and effectively controlled due to the large and small gap between the pipeline and the double-edge cutting sleeve;
(4) the pressure with 500kpa is sealed to test the twolip cutting ferrule, and leakage phenomenon exists in the test process, so that hidden danger exists.
(5) The double-edged ferrule compression nut does not have a locking function.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a pipeline sealing structure suitable for few oily equipment can avoid machining tolerance clearance risk.
In order to achieve the purpose, the utility model adopts the following technical proposal to realize:
the utility model discloses a pipeline sealing structure, including the terminal joint, rubber ring, clamping ring, stopping sword and the gland on the pipeline of establishing in proper order, the rubber ring is with the tip adaptation of terminal joint, the both ends of clamping ring respectively with rubber ring, stopping sword adaptation; the terminal joint sleeve is provided with a backstop nut, and the external thread of the backstop nut is matched with the internal thread of the pressing cap.
Preferably, the end faces of the two ends of the pressing ring incline from outside to inside, one end of the stopping blade is clamped between the pressing ring and the pipeline, and the stopping blade is attached to the end face of the pressing ring.
Preferably, one end of the rubber ring is attached to the end of the terminal connector, the other end of the rubber ring is attached to the pressing ring, and the outer diameter of the pressing ring is larger than that of the rubber ring.
