Description

Technical Field

[0001] This utility model relates to the field of metal products technology, and in particular to a three-way flange connector with connection compensation function. Background Technology

[0002] A tee flange is a device used for pipe connections, primarily for changing the direction of fluid flow or connecting multiple pipes at branches of a main pipeline. It has three ports: one inlet and two outlets, or two inlets and one outlet, arranged in a T- or Y-shape. Tee flanges are widely used in chemical, petroleum, natural gas, and water treatment industries.

[0003] Currently, when connecting tee flanges to pipelines, the tee flanges require extremely high precision; otherwise, they cannot be accurately connected to the pipeline. In addition, during the installation of tee flanges, the curved outer wall makes them difficult to position on the lifting platform, which also brings considerable difficulty to the installation.

[0004] Therefore, it is necessary to develop a tee flange connector with connection compensation function in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tee flange connector with connection compensation function, which can realize quick and accurate connection with external pipelines, improve installation efficiency, and reduce installation difficulty.

[0006] To achieve the above-mentioned utility model objectives, a tee flange connector with connection compensation function is provided, comprising a tee, three bellows, three flanges, and three sets of support components;

[0007] One end of the bellows is welded to the port of the tee fitting, and the other end is welded to the flange fitting;

[0008] Each of the support members includes two pairs of bottom support blocks and one pair of top support blocks;

[0009] In each support component, two pairs of bottom support blocks are symmetrically arranged at the bottom of the tee flange connector;

[0010] In a pair of bottom support blocks, one bottom support block is located at the bottom of the flange, and the other bottom support block is located at the bottom of the corresponding position of the tee.

[0011] All of the aforementioned bottom support blocks have a flat bottom, and are flush with each other;

[0012] In a pair of top support blocks, one top support block is located on the top of the outer wall of the flange, and the other top support block is located on the top of the corresponding tee.

[0013] Each pair of bottom and top support blocks is fitted with a support rod, and both ends of the support rod are threaded with nuts.

[0014] Preferably, each of the bottom support blocks is provided with an anti-slip rubber pad at its bottom.

[0015] Preferably, each of the flanges has a plug-in wall extending along its axial direction on its end face, and the outer diameter of the plug-in wall is adapted to the inner diameter of the pipe to be connected.

[0016] At least two first sealing rings are fitted onto the insertion wall.

[0017] Furthermore, two first sealing rings are fitted onto each plug wall.

[0018] Furthermore, a second sealing ring is inserted into the end face of the flange.

[0019] Preferably, a filter screen is installed at the end of the insertion wall.

[0020] Furthermore, the filter screen has a curved structure.

[0021] Compared with the prior art, the tee flange connector with connection compensation function of this utility model has the following advantages:

[0022] During transportation, the aforementioned tee flange connectors can be securely supported within the transport platform without requiring additional support and fixing mechanisms; during installation, the corrugated pipe provides excellent compensation and freedom of movement, enabling rapid installation with external pipelines.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 As shown, a tee flange connector with connection compensation function in this embodiment includes a tee 1, three bellows 2, three flanges 3, and three sets of support members.

[0030] One end of the bellows 2 is welded to the port of the tee 1, and the other end is welded to the flange 3.

[0031] The three ports of the tee flange connector are all equipped with bellows 2 on the outer wall, which provide good compensation and freedom of movement, and can be quickly installed with external pipelines.

[0032] Each of the aforementioned support members includes two pairs of bottom support blocks 4 and a pair of top support blocks 5; in each support member, the two pairs of bottom support blocks 4 are symmetrically arranged at the bottom of the tee flange connector; in a pair of bottom support blocks 4, one bottom support block is located at the bottom of the flange 3, and the other bottom support block is located at the bottom of the corresponding position of the tee 1; as shown Figure 2 As shown, the bottom of all the bottom support blocks 4 has a flat surface 6, and they are flush.

[0033] In a pair of top support blocks 5, one top support block is located on the top of the outer wall of the flange 3, and the other top support block is located on the top of the corresponding tee 1.

[0034] Each pair of bottom support blocks 4 and top support blocks 5 is fitted with a support rod 7, and both ends of the support rod 7 are threaded with nuts 8.

[0035] With this configuration, on the one hand, all the bottom support blocks 4 have a flat surface 6 at the bottom, which can effectively contact the support surface. During the transportation of the above-mentioned tee flange connectors, they can be effectively and stably supported to prevent them from rolling. On the other hand, the setting of the support columns prevents the bellows 2 from deforming during transportation, which would cause the tee flange connectors to roll. During installation, the bottom support blocks 4 are supported on the lifting platform, and all the support rods 7 are removed. Due to the function of the bellows 2, the interface between the tee flange connectors and the external pipeline can be quickly connected.

[0036] In this embodiment, each bottom support block 4 is provided with an anti-slip rubber pad (not shown in the figure) to prevent it from sliding.

[0037] In this embodiment, as Figure 3As shown, each flange 3 has a plug-in wall 9 extending along its axial direction on its end face. The outer diameter of the plug-in wall 9 is adapted to the inner diameter of the pipe to be connected. At least two first sealing rings 10 are fitted on the plug-in wall 9 to provide a sealing function, while effectively reducing the end face area of ​​the flange and saving materials. In this embodiment, two first sealing rings 10 are fitted on each plug-in wall 9.

[0038] Furthermore, a second sealing ring 11 is inserted into the end face of the flange 3, which works in conjunction with the first sealing ring 10 to achieve a better sealing effect.

[0039] In this embodiment, as Figure 4 As shown, a filter screen 12 is installed at the end of the insertion wall 9, which plays a filtering role on the flowing medium.

[0040] Furthermore, such as Figure 5 As shown, the filter screen 12 has a curved structure, which increases the filtration area and improves the filtration effect.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
