Description

Technical Field

[0001] This utility model belongs to the field of flange structure technology, specifically relating to a plate-type flat-welded steel pipe flange. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, and for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment. Plate-type flat-welded steel pipe flanges specifically refer to steel flanges that are entirely flat and manufactured through welding.

[0003] A plate-type flat-welded steel pipe flange, authorized by CN202320164878.3, includes an outer ring flange, an inner ring flange, an inner ring reinforcing sleeve, a connecting seat, and a connecting block. The inner ring flange is mounted on the outer ring flange; the inner ring reinforcing sleeve is mounted on the inner ring flange. This invention improves the connection stability between multiple stacked plate flanges by using a connecting seat and a connecting block, where the connecting block on the upper flange engages with the connecting seat on the lower flange. Simultaneously, the connecting seat and connecting block are respectively located on the connecting through-hole of the outer ring flange and the center of the inner ring flange, ensuring that the original shaft mounting hole size of the flange is not affected, thus guaranteeing the stability between the flange body and the connecting shaft. This solves the problem that existing flange structures affect the original shaft mounting hole size after the installation of a sealing ring.

[0004] In the above scheme, the flanges are connected by simple bolts and nuts. However, bolts and nuts are prone to loosening, which will affect the sealing of the flange connection, making it easy for water to seep in and causing the bolts to rust, thus affecting the subsequent use of the flanges. Therefore, we propose a plate-type flat-welded steel pipe flange. Utility Model Content

[0005] The purpose of this utility model is to provide a plate-type flat-welded steel pipe flange to solve the problem mentioned in the background art that the flanges are connected by simple bolts and nuts, which are easy to loosen, affecting the sealing performance between the flanges, making it easy for water to seep in, and thus causing the bolts to rust, affecting the subsequent use of the flange.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate-type flat-welded steel pipe flange, comprising a first flange and a second flange, the second flange being snapped onto the right side of the first flange, a connecting ring being fixedly connected to the right side inside the first flange, a connecting groove being provided on the left side inside the second flange, the connecting ring being adapted to the connecting groove, a first connecting block being fixedly connected to both the front and rear sides of the first flange, a second connecting block being fixedly connected to both the front and rear sides of the second flange, a snap-fit ​​block being fixedly connected to the right side of the first connecting block, a snap-fit ​​groove being provided on the left side of the second connecting block, the snap-fit ​​block being adapted to the snap-fit ​​groove, a snap-fit ​​block being movably connected to one end of the snap-fit ​​block, a snap-fit ​​groove being provided at one end of the snap-fit ​​groove, the snap-fit ​​groove extending into the snap-fit ​​groove, and the snap-fit ​​block being adapted to the snap-fit ​​groove.

[0007] Preferably, the connecting ring has a limiting hole on the right side, and a limiting rod is fixedly connected to the left side of the connecting groove. There are four limiting rods and four limiting holes, and they are adapted to each other.

[0008] Preferably, one end of the latching block is provided with a groove, and a spring is provided inside the groove. One end of the spring is fixedly connected inside the groove, and the other end of the spring is fixedly connected to one side of the latching block.

[0009] Preferably, the outer side of the connecting ring is provided with a groove, and a sealing ring is engaged inside the groove.

[0010] Preferably, one end of the snap-fit ​​block is provided with a baffle, the baffle is rotatably connected to one end of the snap-fit ​​block, and the snap-fit ​​block is disposed on the outside of the snap-fit ​​block.

[0011] Preferably, an iron sheet is fixedly connected to the other end of the snap-fit ​​block, and a magnet is fixedly connected to one end of the baffle, with the magnet being magnetically connected to the iron sheet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By engaging the connecting ring on the right side of the first flange into the connecting groove on the left side of the second flange, and engaging the connecting block into the connecting groove, the first flange and the second flange are connected. This can fix the inner and outer rings of the two flanges respectively, improve the sealing between the flanges, prevent water leakage and bolt rusting, and improve the subsequent use effect of the flange.

[0014] 2. By rotating the baffle, the magnet is connected to the iron plate, and the baffle covers the outside of the slot to prevent dust from entering the slot and accidental contact with the locking block. When disassembly is required, the baffle is opened, the locking block is pressed down, the spring extends and retracts, and the locking block enters the groove from the slot, thus separating the locking block from the slot and the locking block from the locking groove, which facilitates the disassembly of the flange.
