[0020] This utility model provides a grooved flange pipe fitting, including a flange 101 and a connecting mechanism 102. The connecting mechanism 102 includes a grooved main pipe 103, a wear-resistant cylinder 104, a threaded cylinder 105, a straight pipe 106, two side pipes 107, and multiple blocking caps 108. The straight pipe 106 includes a straight body 109 and a limiting ring 110. Each side pipe 107 includes a side body 111 and a connecting cylinder 112. Each blocking cap 108 includes a cap body 113 and a supporting post 114. The flange 101 includes a disc body 115 and multiple mounting cylinders 116.

[0021] In this specific embodiment, each blocking cap 108 is detachably connected to the corresponding side passage pipe 107. The inner end of each side passage pipe 107 is fixedly connected to the straight passage pipe 106. The lower end of the straight passage pipe 106 is threadedly connected to the threaded cylinder 105. The threaded cylinder 105 and the wear-resistant cylinder 104 are both fixedly connected to the grooved main pipe 103. The grooved main pipe 103 is fixedly connected to the flange 101. The limiting ring 110 is fixedly connected to the straight body 109. The lower end of the straight body 109 is threadedly connected to the threaded cylinder 105. The connecting cylinder 112 is fixedly connected to the side passage body 111. The side passage body 111 is fixedly connected to the straight body 109. The supporting post 114 is connected to the cap body 113. The cap body 113 is detachably connected to the corresponding side passage body 111. Each mounting cylinder 116 is fixedly connected to the disc body 115. The disc body 115 is fixedly connected to the grooved main pipe 103. The grooved main pipe 103 is connected to a four-way pipe composed of the straight passage body 109 and the two side passage bodies 111, which can adapt to various usage environments. The straight passage body 109 and the grooved main pipe 103 are threadedly connected by the threaded cylinder 105, which is convenient and quick to install. It can also be disassembled and placed when not in use. This design has a simple structure and good practicality. It solves the problem that grooved flange fittings require different specifications of flange bodies to adapt when connecting pipelines in multiple directions, resulting in high production costs and inability to adapt to various usage environments.

[0022] Each of the blocking caps 108 is located at the outer end of the corresponding side passage pipe 107, and the inner end of each side passage pipe 107 is located on both sides of the straight passage pipe 106. The lower end of the straight passage pipe 106 is located inside the threaded cylinder 105. The threaded cylinder 105 and the wear-resistant cylinder 104 are both located on the inner wall of the grooved main pipe 103. The grooved main pipe 103 is located above the flange 101. Each cap body 113 is fixed to the outer end of the corresponding side passage body 111 by a sealing threaded connection. With the fit between the abutment post 114 and the inner wall of the connecting cylinder 112, it is ensured that when the side passage body 111 is closed, liquid will not overflow from the gap.

[0023] Secondly, the limiting ring 110 is located at the upper end of the straight body 109, the lower end of the straight body 109 is located inside the threaded cylinder 105, the connecting cylinder 112 is located on the inner wall of the side body 111, and the side body 111 is located on one side of the straight body 109. A sealing ring is provided at the connection between the wear-resistant cylinder 104 and the threaded cylinder 105 and is fixed at the upper end of the wear-resistant cylinder 104. When the lower end of the straight body 109 is threaded to the bottom of the threaded cylinder 105, it fits against the sealing ring to ensure that the water output from the groove main pipe 103 completely enters the straight body 109, thus ensuring the sealing performance.

[0024] Meanwhile, the supporting post 114 is located inside the cap 113, and the cap 113 is located at the outer end of the corresponding side through-body 111. Each mounting cylinder 116 is located on the periphery of the disc 115, and the disc 115 is located at the lower end of the groove main pipe 103. It should be noted that the outer end of the straight through-body 109 and the outer ends of the two side through-body 111 have the same diameter. Therefore, the diameter of each cap 113 and the corresponding supporting post 114 is equal. The same cap 113 can be fixedly installed at the outer ends of different straight through-body 109 or side through-body 111. In actual use, the disc... After the grooved main pipe 103 is fixed, there are multiple pipe connection methods for the user to choose from. Each time a pipe is passed, one cap 113 is used less. The connecting mechanism 102 is formed as a four-way pipe and outputs from the grooved main pipe 103, which has a better adaptability. In particular, the connecting cylinder 112 is also provided on the inner side wall of the side body 111. The inner wall of each connecting cylinder 112 has multiple wear-resistant strips to increase the friction between it and the corresponding support column 114. Under normal circumstances, the outer ends of the two side bodies 111 are used less frequently, so it is necessary to ensure the sealing effect of the outer ends of the side bodies 111.

[0025] In this embodiment, each cap 113 is fixed to the outer end of the corresponding side passage 111 by a sealing threaded connection. This, combined with the fit between the abutment post 114 and the inner wall of the connecting cylinder 112, ensures that liquid will not overflow from gaps when the side passage 111 is sealed. A sealing ring is provided at the connection between the wear-resistant cylinder 104 and the threaded cylinder 105, fixed to the upper end of the wear-resistant cylinder 104. When the lower end of the straight passage 109 is threaded to the bottom of the threaded cylinder 105, it fits against the sealing ring, ensuring that the water output from the main channel 103 completely enters the straight passage 109, thus guaranteeing a tight seal. It should be noted that the outer diameter of the straight passage 109 is the same as the outer diameter of the two side passages 111. Therefore, each cap 113 and the corresponding abutment post 114... All pipes are of equal diameter. The same cap 113 can be fixedly installed on the outer ends of different straight pipes 109 or side pipes 111. In actual use, after the disc 115 fixes the grooved main pipe 103, there are multiple pipe connection methods for users to choose from. Each pipe reduces the use of one cap 113. The connecting mechanism 102 forms a four-way pipe and outputs from the grooved main pipe 103, which has a better adaptability. In particular, the inner wall of the side pipe 111 is also provided with a connecting cylinder 112. The inner wall of each connecting cylinder 112 has multiple wear-resistant strips to increase the friction between it and the corresponding abutment post 114. Under normal circumstances, the outer ends of the two side pipes 111 are used less frequently, so it is necessary to ensure the sealing effect of the outer ends of the side pipes 111.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
