Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and more specifically, to an anti-leakage ferrule joint. Background Art

[0002] A ferrule fitting is a fitting component used to connect pipes. It is usually made of metal and plastic materials and has the characteristics of durability, corrosion resistance, and anti-static. The ferrule fitting is mainly composed of three parts: the fitting body, the ferrule, and the nut.

[0003] Traditional ferrule fittings have the following shortcomings: if the steel pipe is not inserted to the bottom, the metal ferrule cutting edge cannot cut into the surface of the steel pipe, thereby failing to form an effective secondary sealing ring, which greatly reduces the sealing effect. In addition, if the nut is not tightened, there will not be enough axial thrust, which may cause the primary sealing ring and the secondary sealing ring to fail to form, resulting in leakage. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a leakage-proof ferrule joint, which has the advantage of leakage-proof.

[0005] To achieve the above object, the utility model provides the following technical solution: a leak-proof ferrule joint, comprising:

[0006] A connector body, a cannula is fixedly installed on the left side of the connector body, and a nut is threadedly installed on the outer side of the left end of the connector body;

[0007] A bottom ring block is fixedly installed on the left end of the nut, a connecting block is evenly fixedly installed on the left end of the bottom ring block, and a sealing block is fixedly installed on the left end of the connecting block.

[0008] As a preferred technical solution of the utility model, a sealing ring is movably installed at the left end of the joint body, and a ferrule is movably installed inside the sealing ring.

[0009] As a preferred technical solution of the utility model, an outer ring block is fixedly installed on the outer side of the bottom ring block, and a screw groove is opened on the inner side of the outer ring block.

[0010] As a preferred technical solution of the utility model, a threaded cylinder is installed on the internal thread of the screw groove, and a knob is fixedly installed on the left end of the threaded cylinder.

[0011] As a preferred technical solution of the utility model, a triangular clamping ring is fixedly installed on the right side of the threaded cylinder, and the triangular clamping ring corresponds to the sealing block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model passes the pipeline through the nut, then installs the joint body, the sealing ring and the ferrule on the pipeline in sequence, rotates the nut to fix it, and then rotates the knob to make the knob drive the threaded cylinder to rotate, and the threaded cylinder drives the triangular clamping ring to move downward to squeeze the sealing block and the connecting block, so that they are deformed inward to fix the pipeline. Compared with the traditional ferrule joint, this leak-proof ferrule joint squeezes the connecting block and the sealing block through the downward movement of the triangular clamping ring, so that they are tightened inward to fix the pipeline, thereby improving the sealing performance of the ferrule joint and preventing leakage.

[0024] When installing the ferrule joint, first pass the pipe through the nut 5, then put the sealing ring 3 and the ferrule 4 on the pipe, then insert one end of the pipe into the interior of the joint body 1, so that one end of the pipe fits with the sealing ring 3, then rotate the nut 5, the nut 5 squeezes the ferrule 4, so that one end of the ferrule 4 is embedded in the surface of the pipe, and then rotate the knob 12, so that the knob 12 drives the threaded cylinder 11 to rotate inside the screw groove 13, driving the triangular clamping ring 10 to move downward, so that the triangular clamping ring 10 moves downward to squeeze the sealing block 9 and the connecting block 8, so that the sealing block 9 and the connecting block 8 fit with the pipe, thereby improving the sealing with the pipe.

[0025] Pass the pipe through the nut 5, then install the joint body 1, the sealing ring 3 and the ferrule 4 on the pipe in sequence, rotate the nut 5 to fix it, and then rotate the knob 12 to make the knob 12 drive the threaded cylinder 11 to rotate, and the threaded cylinder 11 drives the triangular clamping ring 10 to move downward to squeeze the sealing block 9 and the connecting block 8, so that they deform inward to fix the pipe. Compared with the traditional ferrule joint, this leak-proof ferrule joint squeezes the connecting block 8 and the sealing block 9 through the downward movement of the triangular clamping ring 10, so that they are tightened inward to fix the pipe, thereby improving the sealing of the ferrule joint and preventing leakage.

[0026] A sealing ring 3 is movably mounted on the left end of the joint body 1 , and a ferrule 4 is movably mounted inside the sealing ring 3 .

[0032] A triangular clamping ring 10 is fixedly installed on the right side of the threaded cylinder 11 , and the triangular clamping ring 10 corresponds to the sealing block 9 .

[0033] The triangular clamp ring 10 moves downward to abut against the sealing block 9, squeezing the sealing block 9 so that the sealing block 9 contracts inward to fix the pipeline, thereby improving the sealing performance of the device.

[0034] The working principle and use process of this utility model:

[0035] When installing the ferrule joint, first pass the pipe through the nut 5, then put the sealing ring 3 and the ferrule 4 on the pipe, then insert one end of the pipe into the interior of the joint body 1, so that one end of the pipe fits with the sealing ring 3, then rotate the nut 5, the nut 5 squeezes the ferrule 4, so that one end of the ferrule 4 is embedded in the surface of the pipe, and then rotate the knob 12, so that the knob 12 drives the threaded cylinder 11 to rotate inside the screw groove 13, driving the triangular clamping ring 10 to move downward, so that the triangular clamping ring 10 moves downward to squeeze the sealing block 9 and the connecting block 8, so that the sealing block 9 and the connecting block 8 fit with the pipe, thereby improving the sealing with the pipe.
