Ring flange convenient to install and capable of preventing excursion

Abstract

The invention relates to the technical field of hardware devices, and discloses a ring flange convenient to install and capable of preventing excursion. The ring flange comprises a first flange; a first connecting port is fixedly connected with the right end of the first flange; a screwing nut is fixedly connected with the surface of the first flange; a fastening bolt is fixedly connected with theleft end of the screwing nut; and a positioning rod is fixedly connected with the surface of the fastening bolt. Through fixed connection between the first flange and a second flange and connection between the second flange and a third flange, the fastening bolt penetrates through a flexible through hole; the third flange is rotated by a certain angle so the positioning rod can be placed in a fixing groove; the screwing nut is fastened at the moment, and the fastening bolt moves inwardly, so the third flange is fixed on the second flange and a sealing ring on the second flange is tightly attached to the third flange; and therefore, the effects that the ring flange is conveniently installed by a worker, installation time is saved, and operation efficiency is greatly improved can be achieved.

Description

technical field [0001] The invention relates to the technical field of hardware devices, in particular to a flange plate which is convenient for installation and capable of preventing displacement. Background technique [0002] Flanges are parts used to connect shafts to each other, and are used for connection between pipe ends; there are also flanges used on equipment inlets and outlets, used for connection between two equipments, and reducer flanges . Flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a team of combined sealing structure. [0003] During the flange installation process, it is necessary to manually install multiple bolts to increase its stability, which increases the working time and reduces work efficiency, and this installation will cause the joints between the flanges to be damaged due to temperature, pressure, Due to the influence of vibration and other factors, the phenomenon of installation dislo...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flange that is easy to install and can prevent offset. It is equipped with a convenient flange installation, which can enhance the sealing performance of the joint, and will not cause flange connection due to vibration and other factors. Leakage caused by loose parts reduces working time, increases work efficiency, prevents installation misalignment, and reminds the installer when the installation is successful, solves the need for manual installation of multiple bolts, increases work time, and reduces work time. Efficiency, and this installation will cause the connection between the flanges to be affected by factors such as temperature, pressure, vibration, etc. During the installation process, there will be a phenomenon of installation misalignment, which will cause leakage problems during the transmission process
