Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A copper three-way joint is shown in figures 1 to 5 and comprises a T-shaped pipe body 1, the pipe body 1 is made of copper alloy, the pipe body 1 comprises three mutually communicated plug-in connectors 2, each plug-in connector 2 comprises an insertion pipe 3, a connector 4 with an external thread structure is arranged on each insertion pipe 3, a connecting rod 5 is arranged on one surface of each insertion pipe 3 facing the connector 4, a first connecting flap 6 and a second connecting flap 7 are hinged on each connecting rod 5, a first fixing plate 8 is arranged at one end, far away from the connecting rod 5, of each first connecting flap 6, a second fixing plate 9 is arranged at one end, far away from the connecting rod 5, of each second connecting flap 7, a bolt 10 is rotatably connected on each first fixing plate 8, a threaded hole 11 matched with the bolt 10 is formed in each second fixing plate 9, extrusion blocks 12 are arranged on the inner walls of the first connecting flaps 6 and the second connecting flaps 7, one surface, facing the connector, the outer peripheral wall of the joint 4 is rotatably connected with a sealing assembly, the sealing assembly comprises a sealing ring 13, an inner ring 14 is arranged on the inner peripheral wall of the sealing ring 13, an annular block 16 is arranged on the inner peripheral wall of the inner ring 14, an annular groove 17 used for clamping the annular block 16 is formed in the outer peripheral wall of the joint 4, a clamping ring 15 is arranged on the outer peripheral wall of the sealing ring 13, a clamping strip 18 is arranged on the outer peripheral wall of the clamping ring 15, and a clamping groove 19 used for clamping the clamping strip 18 to be clamped is formed in the inner walls of the first connecting flap 6 and.

When the three-way joint is used, a pipeline is in threaded connection with the joint 4, then the first connecting petal 6 and the second connecting petal 7 which are hinged on the connecting rod 5 are rotated, so that the first connecting petal 6 and the second connecting petal 7 are close to each other and surround the pipeline until the bolt 10 on the first fixing plate 8 is aligned with the threaded hole 11 on the second fixing plate 9, then the bolt 10 is rotated, so that the bolt 10 is screwed into the threaded hole 11, wherein, as the bolt 10 is rotatably connected on the first fixing plate 8, the second fixing plate 9 is gradually close to the first fixing plate 8 along with the gradual screwing of the bolt 10, so that the distance between the first connecting petal 6 and the second connecting petal 7 is gradually close, so that the extrusion blocks 12 on the inner walls of the first connecting petal 6 and the second connecting petal 7 are gradually pressed against the outer wall of the pipeline, and the outer wall of the pipeline is firmly pressed along with the reduction of the clamping distance between the first connecting petal 6 and the second connecting petal 7, therefore, when high-pressure fluid passes through the pipeline, the pipeline is not easy to loosen due to the impact of the high-pressure fluid, so that the pipeline is more firmly connected with the joint 4, and the sealing performance is better.

Owing to be provided with seal assembly, at pipeline and 4 threaded connection's of joint in-process, the pipeline can be close to the terminal surface of intubate 3 gradually, until extrusion sealing washer 13, wherein because seal assembly and 4 threaded connection of joint, when pipeline contact sealing washer 13, sealing washer 13 can rotate along with the pipeline, thereby avoided sealing washer 13 to receive the extrusion of pipeline on one side, thereby receive the torsional force damage of pipeline on one side, the life of sealing washer 13 has been prolonged, along with the screw in gradually of pipeline, the pipeline can be with sealing washer 13 firmly support press on intubate 3, sealing washer 13 has certain elasticity, can produce elastic deformation after receiving the extrusion force, thereby fill up the space between pipeline and intubate 3, and then make the leakproofness of pipeline improve greatly, be difficult for leaking more.

Because the annular block 16 is arranged on the inner peripheral wall of the inner ring 14, the annular block 16 is clamped into the annular groove 17 on the outer peripheral wall of the joint 4, the annular block 16 rotates in the annular groove 17, the rotary connection between the sealing assembly and the joint 4 is realized, and the annular block 16 is limited by the annular groove 17, so that the sealing assembly can stably and smoothly rotate on the joint 4.

Because be provided with card strip 18 on the snap ring 15 periphery wall, when rotating first connection lamella 6 and second connection lamella 7, card strip 18 can block gradually into draw-in groove 19 in, it is spacing to card strip 18 through draw-in groove 19 for at the in-process that first connection lamella 6 and first connection lamella 6 surround the pipeline, first connection lamella 6 is difficult for rocking with second connection lamella 7, thereby make first connection lamella 6 and second connection lamella 7 more stable to the parcel of pipeline.

Because the face of extrusion piece 12 towards joint 4 is circular-arc, when extrusion piece 12 contradicts the pipeline periphery wall, extrusion piece 12 to the pipeline periphery wall can decompose into along extrusion piece 12 and each tangential direction's of pipeline contact surface component to the tip of having avoided extrusion piece 12 is carved and is caused the indentation on the pipeline outer wall, thereby has prevented that the pipeline outer wall is impaired, has prolonged the life of pipeline.

Because the pipe body 1 is made of copper alloy, the copper alloy has better plasticity and wear resistance, so that the pipe body 1 has better plasticity, is easy to machine and form, has better wear resistance and is not easy to wear, and the service life of the pipe body 1 is greatly prolonged.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
