Description
（一） 技术领域 (1) Technical field
本实用新型涉及一种变压器用管接头，特别涉及一种变压器万向管接头。 The utility model relates to a pipe joint for a transformer, in particular to a universal pipe joint for a transformer.
（二） 背景技术 (2) Background technology
现阶段，35kV及以上电压等级的电力变压器管接头多采用圆管与单个法兰的直接对焊，管道对接时法兰无法旋转，增加对接难度，易使密封垫受力不均，造成变压器渗漏，而且还增加了对接工作量。 At present, the pipe joints of power transformers with a voltage level of 35kV and above are mostly used for direct butt welding of round pipes and single flanges. Leakage, but also increased docking workload.
（三） 发明内容 (3) Contents of the invention
本实用新型为了弥补现有技术的不足，提供了一种结构简单、可操作性高、安全可靠、节约成本的变压器万向管接头。 In order to make up for the deficiencies of the prior art, the utility model provides a transformer universal pipe joint with simple structure, high operability, safety, reliability and cost saving.
本实用新型是通过如下技术方案实现的： The utility model is achieved through the following technical solutions:
一种变压器万向管接头，其特征在于：所述装置包括圆管、母法兰和子法兰；所述圆管与子法兰对焊；所述子法兰上盖有母法兰；所述母法兰上圆盘的下表面压在子法兰上；所述母法兰设有4-8个固定孔。 A transformer universal pipe joint, characterized in that: the device includes a round pipe, a female flange and a sub-flange; the round pipe and the sub-flange are butt-welded; the sub-flange is covered with a female flange; The lower surface of the disc on the female flange is pressed on the sub-flange; the female flange is provided with 4-8 fixing holes.
所述子法兰上没有固定孔。 There are no fixing holes on the sub-flange.
所述母法兰可360度旋转。 The female flange can rotate 360 degrees.
本实用新型使用时，先将母法兰与子法兰分开，将圆管与子法兰焊接在一起，焊接完毕后，将母法兰扣在子法兰上，由于母法兰与子法兰分开，母法兰可360度旋转，使得母法兰便于固定，解决了一般电力变压器管接头用圆管与单个法兰的直接对焊，管道对接时法兰无法旋转，增加对接难度，易使密封垫受力不均，造成变压器渗漏等问题。 When the utility model is used, the mother flange and the sub-flange are separated first, and the round pipe and the sub-flange are welded together. After the welding is completed, the mother flange is buckled on the sub-flange. The flange is separated, and the female flange can be rotated 360 degrees, which makes the female flange easy to fix, and solves the direct butt welding between the round pipe used for the general power transformer pipe joint and the single flange. The uneven stress on the gasket will cause problems such as transformer leakage.

（四） 附图说明 (4) Description of drawings
下面结合附图对本实用新型作进一步的说明。 Below in conjunction with accompanying drawing, the utility model is further described.
图1为本实用新型的结构示意图。 Fig. 1 is the structural representation of the utility model.
图中，1圆管，2母法兰，3子法兰。 In the figure, 1 round pipe, 2 female flanges, 3 sub-flanges.
（五） 具体实施方式 (5) Specific implementation methods
附图为本实用新型的一种具体实施例。该实施例包括圆管1、母法兰2和子法兰3；所述圆管1与子法兰3对焊；所述子法兰3上盖有母法兰2；所述母法兰2上圆盘的下表面压在子法兰3上；所述母法兰2设有4-8个固定孔。所述子法兰3上没有固定孔。所述母法兰2可360度旋转。 Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a round pipe 1, a female flange 2 and a sub-flange 3; the round pipe 1 is butt welded with the sub-flange 3; the sub-flange 3 is covered with a female flange 2; the female flange 2 The lower surface of the upper disc is pressed on the sub-flange 3; the female flange 2 is provided with 4-8 fixing holes. There is no fixing hole on the sub-flange 3 . The female flange 2 can rotate 360 degrees.
本实用新型使用时，先将母法兰2与子法兰3分开，将圆管1与子法兰3焊接在一起，焊接完毕后，将母法兰2扣在子法兰3上，由于母法兰2与子法兰3分开，母法兰2可360度旋转，使得母法兰2便于固定，解决了一般电力变压器管接头用圆管与单个法兰的直接对焊，管道对接时法兰无法旋转，增加对接难度，易使密封垫受力不均，造成变压器渗漏等问题。 When the utility model is used, the mother flange 2 and the sub-flange 3 are separated first, and the round pipe 1 and the sub-flange 3 are welded together. After the welding is completed, the mother flange 2 is buckled on the sub-flange 3. The female flange 2 is separated from the sub-flange 3, and the female flange 2 can be rotated 360 degrees, which makes the female flange 2 easy to fix, and solves the direct butt welding between the round pipe used for the general power transformer pipe joint and the single flange. The flange cannot be rotated, which increases the difficulty of docking, easily causes uneven force on the gasket, and causes problems such as transformer leakage.
