Description

Technical Field

[0001] The utility model relates to the technical field of flange structures, in particular to a flange structure with a sealing and fastening function. Background Technique

[0002] A flange is a common pipe fitting used for pipe connection. When in use, flanges are respectively assembled on the two pipes to be connected, and then the two flanges are fixed together by bolts to complete the installation of the pipes.

[0003] The existing flanges generally consist of two flange plates and a gasket. When in use, the gasket is arranged between the flange plates. However, in the actual installation process, the gasket is prone to shift, resulting in poor sealing between the flange plates. Moreover, a single bolt is often used for flange connection. Over time, if a single bolt falls off, the flange plates will become loose. Therefore, a flange structure with a sealing and fastening function is introduced to solve the above-mentioned problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a flange structure with a sealing and fastening function. Its advantages are that a limit frame is opened on the first flange plate, and a gasket is installed in the limit frame. Therefore, when the first flange plate is connected to the second flange plate, the sealing effect is enhanced, and the situation of the gasket falling off when arranged outside is prevented.

[0005] To achieve the above object, the utility model provides the following technical solution: A flange structure with a sealing and fastening function, including a first flange plate, a fixing hole is opened at the top of the first flange plate, a limit frame is installed on the first flange plate, and a gasket is arranged inside the limit frame.

[0006] Preferably, a limit block is fixedly installed on the outer wall of the first flange plate. The number of limit blocks is four groups, and the four groups of limit blocks are symmetrically installed on the outer wall of the first flange plate, and a second flange plate is installed on the first flange plate.

[0007] Preferably, a fixing plate is installed between the first flange plate and the second flange plate, and a bolt is fixedly installed on the fixing plate.

[0008] Preferably, the number of bolts is several groups and they are symmetrically installed at equal intervals on the fixing plate. The extending end of the bolt is threadedly connected with a nut. By opening a fixing hole on the flange plate, providing a fixing plate on the flange plate, installing bolts on the fixing plate, and providing nuts on the bolts, the bolts are integrally arranged on the fixing plate, avoiding the possibility of a single group of bolts falling off.

[0009] Preferably, the number of fixing holes is several groups and they are symmetrically opened at equal intervals on the first flange plate.

[0010] Preferably, a limiting block is installed on the second flange, and a through hole is provided in the limiting block installed on the first flange.

[0011] Compared with the prior art, the utility model provides a flange structure with a sealing and fastening function, and has the following beneficial effects:

[0012] First, for the flange structure with a sealing and fastening function, a limiting frame is provided on the first flange, and a sealing gasket is installed in the limiting frame. Therefore, when the first flange is connected to the second flange, the sealing effect is enhanced, and the situation that the sealing gasket falls off when arranged outside is prevented.

[0013] Second, for the flange structure with a sealing and fastening function, fixing holes are provided on the flange, and a fixing plate is arranged on the flange. Bolts are installed on the fixing plate, and nuts are arranged on the bolts. Therefore, the bolts are integrally arranged on the fixing plate, avoiding the possibility of a single set of bolts falling off. BRIEF DESCRIPTION OF THE DRAWINGS
