Technical Field
[0001] The utility model relates to the technical field of MPP pipe joints, in particular to an MPP pipe joint with good sealing performance. Background Art
[0002] MPP pipe joints usually refer to the joints of polypropylene pipes. MPP pipe is a commonly used pipe material with corrosion resistance, heat resistance, and aging resistance. Pipe joints are used to connect different pipe sections or pipes with other pipe components to ensure the integrity and stability of the pipe system.
[0003] There are at least the following disadvantages in the use of existing MPP pipe joints: 1. After the existing MPP pipe joints are inserted and connected with the pipeline, there is often a gap between the outer surface of the pipeline and the inner wall of the joint, which affects the sealing between the joint and the pipeline; 2. The existing MPP pipe joints lack buffer protection measures on the outside. After being bumped, the outer surface of the joint is easily deformed and damaged, thereby affecting the sealing. Therefore, we introduce an MPP pipe joint with good sealing performance. Utility Model Content
[0004] The main purpose of the utility model is to provide an MPP pipe joint with good sealing performance, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] An MPP pipe joint with good sealing performance comprises a joint body, wherein the left end and the right end of the joint body are both provided with an outward expansion part, and the outer surface of the joint body is sleeved with a protective device.
[0007] Preferably, the left and right outer surfaces of the connector body are fixedly connected with feeding ports, the outer surfaces of the two feeding ports are provided with external threads, the two feeding ports are threadedly connected with covers via external threads, and the outer surfaces of the two covers are polygonal structures.
[0008] Preferably, both the left inner wall and the right inner wall of the joint body are provided with cavities.
[0009] By adopting the above technical solution: after the cavity is filled with the sealant, the gap between the joint body and the external pipe will be filled.
[0010] Preferably, the two cavities are communicated with two feeding ports respectively.
[0011] Preferably, the protective device includes a ring, a rubber protective layer is fixedly connected to the outer surface of the ring, the rubber protective layer is a corrugated structure, a No. 1 circular hole is opened on the left and right outer surfaces of the rubber protective layer, and a No. 2 circular hole is opened on the left and right outer surfaces of the ring.
[0012] By adopting the above technical solution, the sleeve ring can fix the rubber protective layer on its outer surface to prevent the rubber protective layer from being deformed or stacked together.
[0013] Preferably, the positions of the two No. 2 circular holes correspond to the positions of the other two No. 1 circular holes, and the two No. 2 circular holes and the two No. 1 circular holes are respectively interspersed with the two feeding ports.
[0014] Preferably, the collar is movably connected to the outer surface of the connector body through insertion.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] 1. Two feeding ports are arranged on the joint body. After the two ends of the external pipe and the joint body are inserted together, the covers on the two feeding ports are removed, and the sealant is injected into the cavity in the joint body from the feeding ports. After the sealant fills the cavity, the cover is connected to the feeding port to seal the feeding port. Under the action of the sealant, the joint body and the external pipe can be sealed to avoid leakage.
[0017] 2. A protective device is arranged on the outer surface of the joint body, and the sleeve is connected to the outer surface of the joint body. Since a corrugated rubber protective layer is fixed on the outer surface of the sleeve, when the joint body is subjected to external force, the rubber protective layer buffers the impact of the external force to prevent the joint body from being damaged or deformed.

[0026] See also Figure 1-4 , the utility model provides a technical solution:
[0027] An MPP pipe joint with good sealing performance comprises a joint body 1. The left and right ends of the joint body 1 are both provided with an expansion portion 2. The outer surface of the joint body 1 is sleeved with a protective device 3.
[0028] In this embodiment, the left and right outer surfaces of the joint body 1 are fixedly connected with a feeding port 11, the outer surfaces of the two feeding ports 11 are provided with external threads 12, and the two feeding ports 11 are threadedly connected with a cover 13 through the external threads 12, and the outer surfaces of the two covers 13 are both polygonal structures; the left and right inner wall of the joint body 1 are provided with a cavity 14; the two cavities 14 are respectively connected to the two feeding ports 11.
[0029] Through the above scheme: the sealant is injected into the cavity 14 through the feeding port 11, and under the action of the sealant, the gap between the joint body 1 and the external pipe is filled, thereby improving the sealing performance and facilitating use.
[0030] In this embodiment, the protective device 3 includes a ring 31, and a rubber protective layer 33 is fixedly connected to the outer surface of the ring 31. The rubber protective layer 33 is a corrugated structure. A No. 1 circular hole 32 is opened on the left and right parts of the outer surface of the rubber protective layer 33, and a No. 2 circular hole 34 is opened on the left and right parts of the outer surface of the ring 31; the positions of the two No. 2 circular holes 34 correspond to the positions of the other two No. 1 circular holes 32, and the two No. 2 circular holes 34 and the two No. 1 circular holes 32 are respectively interspersed with the two feeding ports 11; the ring 31 is interspersed and movably connected with the outer surface of the joint body 1.
[0031] Through the above scheme: the ring 31 wraps the outer surface of the joint body 1, and the ring 31 supports the rubber protective layer 33 fixed on its outer surface. After the joint body 1 is hit by external force, the rubber protective layer 33 buffers the external force to avoid damage and deformation.
[0032] It should be noted that the utility model is an MPP pipe joint with good sealing performance. During use, after the external pipe is accurately connected to the two ends of the joint body 1, the user only needs to easily remove the covers 13 on the two feeding ports 11, and then directly inject the sealant into the cavity 14 inside the joint body through the feeding port. As the sealant gradually fills, the cavity 14 is completely filled. At this time, the cover 13 is quickly reset and fastened to the feeding port 11 to achieve immediate and effective blocking. Not only does it ensure the reliability of the seal, but it also effectively prevents potential leakage risks and improves the overall safety and stability. In order to further improve the durability and protection performance of the joint body 1, a protective device 3 is installed on its outer surface. The ring 31 is sleeved on the joint body 1, and the outer surface of the ring is tightly fitted with the corrugated rubber protective layer 33. When the joint body 1 encounters external impact or stress, the rubber protective layer 33 can effectively absorb and disperse the impact force with its unique corrugated structure and excellent elasticity, thereby significantly reducing direct damage to the joint body, avoiding deformation or damage, and ensuring the long-term stable operation and service life of the joint.
