Problems solved by technology
This increases the workload of the staff, and the joints made by ourselves often have misaligned joints and insufficient hole spacing. It is necessary to re-drill and align the holes, which wastes a lot of maintenance time and greatly reduces work efficiency.
[0003] So now we need this new type of joint, which can be effectively connected with any oil pipe flange, without worrying about the hole position being incorrect, so that the screw cannot pass through

Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be described in further detail: as figure 1 A screw position adjustable oil pipe flange joint is shown, the joint includes an inner disc 1 and an outer ring 2, the inner disc 1 is placed in the ring of the outer ring 2 and both are concentrically arranged, the inner disc 1 The outer diameter of the outer ring is smaller than the inner diameter of the outer ring 2. The inner disc 1 is connected with the outer ring 2 through four rotating devices. The inner disc 1 can rotate relative to the outer ring 2 by means of the rotating device. There are four strip-shaped screw holes 3, the extension lines of the four strip-shaped screw holes 3 intersect with the center of the inner disk 1, and the four strip-shaped screw holes 3 are along the circumference of the inner disk 1 The directions are uniformly distributed, the center of the inner disc (1) is a flow hole 4, and the surroun...

The invention discloses an oil pipe flange plate connector with the screw rod positions capable of being adjusted, and relates to the technical field of oil pipe connecting devices. The oil pipe flange plate connector comprises an inner plate and an outer ring. The inner plate is arranged in a ring circle of the outer ring, and the inner plate and the outer ring are concentrically arranged. The inner plate is connected with the outer ring through four rotating devices. The inner plate can rotate automatically relative to the outer ring by the aid of the rotating devices. Four bar-shaped screw rod through holes are formed in a plate body of the inner plate. Extension lines of the four bar-shaped screw rod through holes all intersect with the plate center of the inner plate. The four bar-shaped screw rod through holes are evenly distributed in the circumferential direction of the inner plate. The plate center of the inner plate is provided with a circulating hole. The periphery of the circulating hole is provided with a sealing convex face in butt joint with flange plates. The oil pipe flange plate connector can be suitable for the flange plates of any size, the screw rod positions are adjustable, and the phenomenon that screw rods cannot penetrate through due to disalignment of hole locations does not need to be worried about.
Description
technical field [0001] The invention relates to the technical field of oil pipe connecting devices. Background technique [0002] Transformer maintenance professionals need to frequently charge and discharge transformer oil, which requires multiple replacements of the joints connecting the pipelines during the maintenance process. This increases the workload of the staff, and the joints made by ourselves often have misaligned holes and insufficient hole spacing. It is necessary to re-drill and align the holes, wasting a lot of maintenance time and greatly reducing work efficiency. [0003] So now there is a need for this new type of joint, which can be effectively connected to any oil pipe flange, without worrying that the hole position is not correct and the screw cannot pass through. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an oil pipe flange connector with adjustable screw position. The connector can b...
