[0038] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0039] Please see Figure 1 This application provides a tee pipe sealing device 1, including a tee jacket 11 and three end caps 12. The tee jacket 11 is used to install on the outside of the tee pipe and has three ends 111. The three end caps 12 are respectively installed on the three ends 111. The end cap 12 includes a straight section 121 and a contraction section 122 connected to each other. The straight section 121 is connected to the end 111, and the contraction section 122 is connected to the end of the straight section 121 away from the end 111. The inner diameter of the contraction section 122 gradually decreases from the end connected to the straight section 121 to the end away from the straight section 121.

[0040] The tee jacket 11 is installed on the outside of the tee pipe, allowing it to fit over the pipe and thus sealing it. However, due to gaps between the tee jacket 11 and the pipe, leakage may occur through the gap between the end 111 of the tee jacket 11 and the pipe. To address this issue, in this embodiment, end caps 12 are installed at all three ends 111 of the tee jacket 11. Each end cap 12 includes a straight section 121 and a contraction section 122. The contraction section 122 is connected to the end of the straight section 121 furthest from the end 111 of the tee jacket 11. The inner diameter of the contraction section 122 gradually decreases from the end connected to the straight section 121 to the end furthest from it, thereby reducing the gap between the end 111 of the tee pipe sealing device 1 and the pipe, and preventing leakage from the end 111.

[0041] In some embodiments, the outer diameter of the contraction section 122 also gradually decreases from the end connected to the straight section 121 to the end away from the straight section 121, which makes it easier to identify the contraction section 122 and the straight section 121 of the end cap 12, and indirectly reduces the time required to install the end cap 12 on the end 111 of the tee jacket 11.

[0042] In some embodiments, the tee sleeve 11 and the end cap 12 are connected by bolts.

[0043] Please continue reading. Figure 1 In some embodiments, the end 111 of the tee sleeve 11 is provided with a first groove 1111, and the end of the straight section 121 away from the contraction section 122 is provided with a first protrusion 1211 that can be embedded in the first groove 1111.

[0044] When the end cap 12 is installed on the end 111 of the tee sleeve 11, the first protrusion 1211 of the straight section 121 away from the contraction section 122 is aligned with the first groove 1111 of the end 111 of the tee sleeve 11. When the straight section 121 is connected to the end 111 of the tee sleeve 11, the first protrusion 1211 is embedded in the first groove 1111. The cooperation between the first protrusion 1211 and the first groove 1111 can enhance the sealing between the straight section 121 and the end 111 of the tee sleeve 11, and further prevent leakage between the end cap 12 and the end 111 of the tee sleeve 11.

[0045] In some embodiments, the end 111 of the tee jacket 11 may be provided with a plurality of first grooves 1111, and the end of the straight section 121 away from the contraction section 122 may be provided with a plurality of first protrusions 1211, with each of the first protrusions 1211 corresponding to a one-to-one correspondence with a plurality of first grooves 1111. When the end cap 12 is installed on the end 111 of the tee jacket 11, each first protrusion 1211 is embedded in the corresponding first groove 1111. The cooperation of the plurality of first protrusions 1211 and the plurality of first grooves 1111 can further enhance the sealing performance of the gap between the straight section 121 and the end 111 of the tee jacket 11, and further prevent leakage between the end cap 12 and the end 111 of the tee jacket 11.

[0046] Please see Figure 2 In some embodiments, a first seal 131 is provided in the first groove 1111.

[0047] When the end cap 12 is installed on the end 111 of the tee sleeve 11, the first protrusion 1211 is embedded in the first groove 1111, and the first seal 131 is pressed into the first groove 1111 by the first protrusion 1211. The first seal 131 can further enhance the sealing between the straight section 121 and the end 111 of the tee sleeve 11.

[0053] When the gland 14 is installed on the end cap 12, the second protrusion 141 provided on the gland 14 is aligned with the second groove 1221 provided on the end of the contraction section 122 away from the straight section 121. When the gland 14 is connected to the end of the contraction section 122 away from the straight section 121, the second protrusion 141 is embedded in the second groove 1221. The cooperation between the second protrusion 141 and the second groove 1221 can enhance the sealing between the gland 14 and the contraction section 122, and further prevent leakage from the end of the end cap 12 away from the end 111 of the tee sleeve 11.

[0054] In some embodiments, the end of the contraction section 122 away from the straight section 121 may be provided with a plurality of second grooves 1221, and the pressure cap 14 may be provided with a plurality of second protrusions 141, with each second protrusion 141 corresponding to a different second groove 1221. When the pressure cap 14 is installed on the end of the contraction section 122 away from the straight section 121, each second protrusion 141 is embedded in the corresponding second groove 1221. The cooperation between the plurality of second protrusions 141 and the plurality of second grooves 1221 can further enhance the sealing performance of the gap between the pressure cap 14 and the contraction section 122, and further prevent leakage at the end of the end cap 12 away from the end 111 of the tee jacket 11.

[0055] Please see Figure 4 In some embodiments, a second seal 132 is provided in the second groove 1221.

When the tee jacket 11 is installed on the outside of the tee pipe, the first jacket shell 112 is first fitted against one side surface of the tee pipe, and the second jacket shell 113 is fitted against the other side surface of the tee pipe. Then, the first jacket shell 112 and the second jacket shell 113 are connected, thereby enabling the tee jacket 11 to be installed on the outside of the tee pipe.

[0060] In this embodiment, when the tee jacket 11 is installed on the outside of the tee pipe, the third protrusion 1131 on the edge of the second jacket shell 113 is aligned with the third groove 1121 on the first jacket shell 112. When the first jacket shell 112 and the second jacket shell 113 are assembled, the third protrusion 1131 is embedded in the third groove 1121. The cooperation between the third protrusion 1131 and the third groove 1121 can enhance the sealing of the gap between the first jacket shell 112 and the second jacket shell 113, and further prevent the tee jacket 11 from leaking.

[0061] In some embodiments, the edge of the first jacket shell 112 may have multiple third grooves 1121, and the edge of the second jacket shell 113 may have multiple third protrusions 1131, with each third groove 1121 corresponding to one of the third protrusions 1131. When the first jacket shell 112 and the second jacket shell 113 are assembled, each third protrusion 1131 is embedded in its corresponding third groove 1121. The cooperation between the multiple third protrusions 1131 and the multiple third grooves 1121 further enhances the sealing between the first jacket shell 112 and the second jacket shell 113, thereby further preventing leakage between them.
