Problems solved by technology

This traditional flange connection method relies more on the alignment accuracy between the flange hole and the flange hole, so as to make the bolt connection more stable. Once the machining accuracy between the flange hole and the flange hole decreases or the alignment accuracy Not high, it is easy to cause unstable connection between pipes

Embodiment 1

[0034] see Figure 1 ~ Figure 3 , a nut type looper flange structure provided in this embodiment mainly includes a nut looper 1, a first necked flange 5, a second necked flange 4 and a jack screw 2, wherein the first necked flange The flange 5 and the second necked flange 4 mainly refer to flanges used to connect with pipelines. Of course, in other scenarios, they can also refer to flanges connected to other components or platforms. This application aims to form an alternative The structure of the connection between traditional flanges does not go into details about the parts connected outside the flange.

[0035]In this embodiment, the inner surface of one end of the nut looper 1 is processed with a connecting thread, and the inner surface of the other end is formed with an annular convex edge 16, and along the axial direction of the nut looper 1, the annular convex edge 16 is processed with a threaded thread. The hole 15 means that the annular convex edge 16 is formed in th...

Embodiment 2

[0053] see Figure 5 , this embodiment also provides a nut-type looser flange combination tool, including the operation wrench 7 and the nut-type looser flange structure described in Embodiment 1. It should be noted that the nut-type looser flange structure in this embodiment The sleeve flange structure is further defined and optimized on the optional scheme of embodiment 1, that is, there are multiple threaded through holes 15 in the nut type looper flange structure, and the plurality of threaded through holes 15 are around the axis of the nut looper 1 The circumferential direction is evenly distributed on the annular convex edge 16, the number of jacking screws 2 is equal to the number of threaded through holes 15, and a single jacking screw 2 is threaded with a single threaded through hole 15, which is suitable for multiple threaded through holes 15 form, the remaining part is consistent with the selection range described in Embodiment 1, and in this embodiment, the outer s...

Abstract

The invention discloses a nut type lap joint flange structure and a combination tool, which are characterized in that flanges of a first hubbed flange and a second hubbed flange are arranged in a nut lap joint, one of the flanges is fixed through threads, the other one is fixed through a pushing screw, so that the flanges of the first hubbed flange and the second hubbed flange are hermetically and stably connected, and the mode that a transmission flange hole is aligned with a flange hole and then a bolt is screwed in to achieve connection is replaced. Generally speaking, the nut type lap joint flange structure and the combination tool can achieve sealing connection between the flanges, a traditional mode that multiple flange holes are connected is not needed, the requirement for installation precision is lowered, operation convenience is improved, and in addition, on the premise that the connection stability between the flanges is guaranteed, disassembly and assembly are better.

Description

technical field [0001] The invention relates to the technical field of flange connection, in particular to a nut type looper flange structure and a combined tool. Background technique [0002] At present, pipes are generally connected by flanges formed at their ends. The flanges of the two pipes are aligned with each other. After the alignment is completed, the two aligned screw holes are fixed together by the cooperation of bolts and nuts. Thereby, the fixed connection between the two pipeline flanges is completed. This traditional flange connection method relies more on the alignment accuracy between the flange hole and the flange hole, so as to make the bolt connection more stable. Once the machining accuracy between the flange hole and the flange hole decreases or the alignment accuracy Not high, it is easy to cause unstable connection between pipelines. [0003] In view of this, this application is proposed. Contents of the invention [0004] The purpose of the pre...
