[0023] EMBODIMENT

[0024] As Figures 1-5 shown, an angle-adjustable elbow three-way flange adapter includes a three-way adapter main body 1, three connecting pipes 2, an installation pipe 3, a flange plate 4 and an angle adjusting mechanism. The connecting pipes 2 are installed on the outer side of the three-way adapter main body 1. The three-way adapter main body 1 can be connected with the elbow flanges of three directions of pipe through the connecting pipes 2 and other components. The connecting pipes 2 can connect the three-way adapter main body 1 and the installation pipe 3.

[0025] As shown in Figures 1-3 , the mounting pipe 3 is mounted on one end of the connecting pipe 2, the flange plate 4 is fixedly arranged on the outer wall of one end of the mounting pipe 3, and the sealing rubber ring 31 is fixedly arranged on the inner wall of the end of the mounting pipe 3 away from the connecting pipe 2. The mounting pipe 3 can connect the connecting pipe 2 and the flange plate 4, and the mounting pipe 3 can be connected and mounted between the flange plate 4 and the fixing member of the external pipeline. The sealing rubber ring 31 can seal between the mounting pipe 3 and the fixing member of the external pipeline.

[0026] As shown in Figures 1-3 , the angle adjusting mechanism is arranged between the connecting pipe 2 and the mounting pipe 3. The angle adjusting mechanism comprises a limiting ring 5 fixedly arranged on the inner wall of one end of the connecting pipe 2 away from the three-way adapter main body 1, and a spherical ball 51 rotatably arranged in the limiting ring 5. The mounting pipe 3 is fixedly arranged in the spherical ball 51 and communicates with the connecting pipe 2. The limiting ring 5 can connect the connecting pipe 2 and the spherical ball 51, and the middle part of the spherical ball 51 is located in the limiting ring 5, so that the spherical ball 51 can rotate on the limiting ring 5 without being separated. After the spherical ball 51 rotates, the angle of the mounting pipe 3 can be adjusted.

[0027] As shown in Figures 2-3 , a rubber ring 53 for pressing and sealing the connecting part of the limiting ring 5 and the spherical ball 51 under the pressure in the pipeline is fixedly arranged between the connecting pipe 2 and the inner side of the limiting ring 5. A sealing ring 52 is fixedly arranged on the side of the limiting ring 5 away from the three-way adapter main body 1. The sealing ring 52 and the rubber ring 53 abut on the outer walls of the two ends of the spherical ball 51 respectively. The sealing ring 52 can seal the connecting part of the limiting ring 5 and the spherical ball 51.

[0028] By rotating the spherical ball 51 in the limiting ring 5, the angle of the flange plate 4 and other components can be adjusted, which is convenient for the flange adapter to connect the pipelines arranged at an angle, has a wide range of application, and when the pressure in the pipeline is large, the rubber ring 53 can be firmly pressed on the connecting part of the spherical ball 51 and the limiting ring 5. In combination with the sealing of the sealing ring 52, the sealing effect between the spherical ball 51 and the limiting ring 5 can be improved to ensure the normal use of the elbow three-way flange adapter.

[0029] As shown in Figures 1-2 , a plurality of mounting holes 41 for bolts to pass through are arranged in the flange plate 4 in a circumferential array. During installation, the bolts can pass through the mounting holes 41 to connect the flange plate 4 and the fixing member of the external pipeline. Then, nuts are screwed on the outer sides of the bolts to abut on the flange plate 4, so as to mount and fix the flange plate 4 and the external pipeline.

[0030] As shown in Figure 1 , Figure 4 , and Figure 5As shown, the flange plate 4 is provided with a protection mechanism for protecting the bolt and nut connection after installation, which includes a plurality of bellows 42 fixed on one side of the flange plate 4 close to the three-way adapter body 1 and used to cover the bolt and nut connection after installation. The end of the bellows 42 away from the flange plate 4 is fixedly provided with a connecting ring 43, the inner wall of the connecting ring 43 is fixedly provided with a first elastic diaphragm 44 and a second elastic diaphragm 45 distributed in a staggered manner on both sides, the first elastic diaphragm 44 and the second elastic diaphragm 45 are matched and overlapped, the connecting ring 43 can connect the bellows 42, the first elastic diaphragm 44 and the second elastic diaphragm 45, and the bellows 42 can connect the connecting ring 43 and the flange plate 4.

[0031] The bellows 42, the first elastic diaphragm 44 and the second elastic diaphragm 45 can cover the bolt and nut connection on the flange plate 4, so that the bolt and nut connection is not easily contacted by external rainwater, rusted and difficult to rotate, thereby prolonging the service life of the bolt and nut on the flange plate 4. Through the overlapping of the first elastic diaphragm 44 and the second elastic diaphragm 45, the bolt can normally pass between the first elastic diaphragm 44 and the second elastic diaphragm 45 during installation, and the end of the bellows 42 can be sealed after installation, so as to seal the inside of the bellows 42 and prevent external rainwater from entering the bellows 42.

[0032] It should be noted that the angle-adjustable elbow three-way flange adapter can be used by first rotating the inner spherical ball 51 of the limiting ring 5 according to the inclination angle of the external pipeline, so as to adjust the angle of the flange plate 4 and other components, so that the flange plate 4 can be matched and aligned with the fixing member of the external pipeline. When the pressure in the pipeline is relatively large, the rubber ring 53 is firmly pressed at the connection between the spherical ball 51 and the limiting ring 5, and the sealing effect between the spherical ball 51 and the limiting ring 5 is improved through the sealing of the sealing ring 52, so as to ensure the normal use of the elbow three-way flange adapter.

[0033] During installation, the bolt can be passed through the mounting hole 41 to connect the flange plate 4 and the fixing member of the external pipeline, and then the nut abutting against the flange plate 4 is screwed on the outside of the bolt, so as to install and fix the flange plate 4 and the external pipeline.

[0034] The bellows 42, the first elastic diaphragm 44 and the second elastic diaphragm 45 can cover the bolt and nut connection on the flange plate 4, so that the bolt and nut connection is not easily contacted by external rainwater, rusted and difficult to rotate, thereby prolonging the service life of the bolt and nut on the flange plate 4.

[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model.
