Description

Technical Field

[0001] The utility model relates to the technical field of flange design, in particular to a threaded flange with a stable installation structure. Background Art

[0002] Threaded flange, also known as threaded flange, is a special flange connection method. Its principle is to process the inner hole of the flange into a pipe thread and connect it with a pipe with an external thread. The installation and disassembly process of the threaded flange is simple and quick, without welding, which reduces the construction difficulty.

[0003] Threaded flanges are fixed with bolts. After being exposed to wind and sun for a long time, the bolts will be corroded by moisture and rust, resulting in a decrease in the bearing capacity of the bolts. The rusted bolts will cause liquid leakage between the flanges, reducing the sealing performance of the flange connection and having limitations.

[0004] The reason for this problem is that the bolts are corroded by moisture and air over time, causing them to rust and form a layer of rust covering their surface. The volume of this rust layer is usually several times the original diameter of the bolt. Under the condition of the same bolt torque, the presence of rust reduces the actual diameter of the bolt, which will lead to a decrease in the bolt's load-bearing capacity. Severe bolt corrosion will increase the gap between the flanges, thus affecting the sealing effect. In environments with high pressure or corrosive media, this decline in sealing performance can lead to leakage or safety accidents. Therefore, we propose a threaded flange with a stable mounting structure to solve the above problems. Utility Model Content

[0026] The embodiment of the utility model discloses a threaded flange with a stable installation structure.

[0027] According to the attached Figure 1-5As shown, it includes a threaded flange 1, which includes a first flange plate 11 and a second flange plate 12.

The function of the clamp is to pre-fix the first protective shell 21 and the second protective shell 22, and to perform secondary fixation by tightening the bolts 13, thereby ensuring the stability of the installation and meeting the needs of users.

[0028] When the device is in use, the first flange 11 and the second flange 12 are rotated and connected to the pipeline, and the first flange 11 and the second flange 12 are pressed together so that the sealing ring 28 is stuck into the inside of the sealing groove 29, and the groove 26 is aligned with the rotating rod 23, and the rotating rod 23 is rotated so that the clamping block 24 is stuck into the inside of the groove 26, and the insertion rod 25 is pushed inward so that the insertion rod 25 is inserted into the inside of the slot 27, so that the rotating rod 23 does not rotate, and the first flange 11 and the second flange 12 are fixed together. At this time, the fastening bolt 13 is inserted from one side of the second protective shell 22 and threadedly connected to the first flange 11 to complete the secondary fixation of the first flange 11 and the second flange 12, ensuring the stable installation of the first flange 11 and the second flange 12, and no liquid leakage occurs, meeting the needs of users.
