Description

Technical Field

[0001] The utility model relates to the technical field of three-way pipe fittings, in particular to a three-way joint assembly. Background Art

[0002] A tee is a pipe joint with three openings, which is widely used in pipe networks for transporting liquids and gases.

[0003] Existing tee pipes, such as the highly sealed tee pipe fitting disclosed in Chinese patent CN219639737U, realize the pipe connection requirements applicable to different working conditions and improve the convenience of use when connecting the pipes by means of a telescopic hose connected between the tee pipe body and the external pipe. However, this structure is to first connect the assembly sleeve at one end of the telescopic hose to the tee pipe body by screw rotation, and then connect the flange at the other end of the telescopic hose to the flange of the external pipe. After one end of the telescopic hose is connected to the tee pipe body by rotation, the flange at one end of the telescopic hose is likely to be unable to accurately align with the bolt hole on the flange of the external pipe. Although the telescopic hose can be telescoped and bent, it is usually inconvenient to twist it, resulting in the inability to smoothly pass the bolts through the flange for installation, thereby failing to ensure a smooth connection.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 6In an embodiment of the present invention, a three-way joint assembly includes a three-way pipe body 1 and three sets of telescopic hoses 2. A first joint 3 is provided at one end of the telescopic hose 2, and a first thread 4 is provided on the surface of the first joint 3. A second joint 5 is provided at the end of the telescopic hose 2 away from the first joint 3, and a screw sleeve 6 is embedded on the outer surface of the second joint 5. A docking ring 7 is provided on the inner side of the end of the three-way pipe body 1, and a second thread 8 is provided on the outer surface of the end of the three-way pipe body 1 to threadably cooperate with the screw sleeve 6.

[0023] Wherein, a clamping assembly is provided between the second joint 5 and the screw sleeve 6;

[0024] The first thread 4 on the surface of the first joint 3 is threadedly matched with the end of the external pipe. First, align the first joint 3 with the end of the external pipe. The telescopic hose 2 can be connected to the external pipe by rotating the first joint 3. At this time, the second joint 5 at the other end of the telescopic hose 2 is inserted into the end of the tee pipe body 1. The nested screw sleeve 6 on the second joint 5 will be aligned with the end of the tee pipe body 1. The screw sleeve 6 can be rotated on the second joint 5 through the clamping assembly, and the screw sleeve 6 cannot move axially along the surface of the second joint 5. Since the screw sleeve 6 and the second thread 8 are threadedly matched, it can be tightened to the tee by rotating the screw sleeve 6. When the end of the through-tube body 1 is twisted, the screw sleeve 6 will drive the second joint 5 to extend into the interior of the tee tube body 1, and the telescopic hose 2 itself will not rotate during this process. Until the end of the second joint 5 conflicts with the docking ring 7 in the end of the tee tube body 1, the end of the telescopic hose 2 can be tightly connected with the tee tube body 1, and then the tee tube body 1 and the external pipeline are connected together through the telescopic hose 2. While being suitable for pipeline connection requirements in different working conditions, there is no need to twist the telescopic hose 2 after connecting one end of the telescopic hose 2, which makes the connection process more convenient and ensures a smooth connection.

[0025] In one embodiment of the present invention, the clamping assembly includes a clamping ring 9 provided at one end of the screw sleeve 6 and an annular clamping groove 10 provided on the outer surface of the second joint 5 for the clamping ring 9 to extend into;

[0026] Since the snap ring 9 extends into the interior of the annular groove 10, the snap ring 9 can rotate inside the annular groove 10 but cannot move out of the outside of the annular groove 10. Therefore, under the restriction of the snap ring 9 and the annular groove 10, the screw sleeve 6 can rotate on the second joint 5 but cannot move axially along the surface of the second joint 5.

[0027] In another embodiment of the present invention, the outer surface of the screw sleeve 6 is evenly distributed with anti-slip grooves 11;

[0028] While the screw sleeve 6 is being rotated, the anti-slip grooves 11 can increase the friction between the hand and the surface of the screw sleeve 6 , thereby making it easier for people to tighten the screw sleeve 6 onto the end of the three-way pipe body 1 .

[0029] In another embodiment of the present invention, a sealing ring 12 is installed at the end of the second joint 5, and a sealing groove 13 is provided on the docking ring 7 to match the sealing ring 12;

[0030] When the end of the second joint 5 contacts the docking ring 7, the sealing ring 12 will extend into the interior of the sealing groove 13. At this time, the occlusal sealing effect of the sealing ring 12 and the sealing groove 13 can enhance the sealing performance of the joint between the second joint 5 and the docking ring 7, thereby preventing the medium in the tee pipe body 1 from leaking out.

[0031] In another embodiment of the present invention, a filter screen 14 is installed inside the three-way pipe body 1;

[0032] The filter screen 14 can intercept impurities in the medium flowing through the three-way pipe body 1 to prevent the impurities from flowing into other external pipes.

[0033] In another embodiment of the present invention, an anti-corrosion layer is provided on the inner walls of the three-way pipe body 1 and the telescopic hose 2;

[0034] The anti-corrosion layer can prevent the three-way pipe body 1 and the telescopic hose 2 from being corroded by the medium flowing through the inside thereof, thereby ensuring the service life of the three-way pipe body 1 and the telescopic hose 2.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
