Abstract

The invention discloses a liquid level meter connecting pipe installing, welding and locating device and a use method thereof. The device comprises a main beam (1) and two locating cover boards (2) located on the same side face at the two ends of the main beam (1). The main beam (1) and the locating cover boards (2) are fixedly connected. The locating cover boards (2) are connected with liquid level meter connecting pipes (5). By the utilization of the provided device, the liquid level meter connecting pipes of a chemical container can be prevented from deforming in the installing and welding and thermal treatment processes, and the requirements for the installation perpendicularity, the interval size and the like of the liquid level meter connecting pipes are effectively met. The device is simple in structure and convenient to install, and the size of the liquid level meter connecting pipes of different size specifications and connecting components of the liquid level meter connecting pipes can be controlled by adjusting the length of the main beam and the size specifications of the locating cover boards and connecting pieces.

Description

technical field [0001] The invention relates to the field of mechanical processing and positioning, in particular to a positioning device for assembly welding of a liquid level gauge connecting pipe and a method for using the same. Background technique [0002] The liquid level gauge is a commonly used nozzle setting for pressure vessels. It is used to measure the storage capacity of the measured medium in the pressure vessel, so as to ensure the continuous supply of required materials in each link of production or to carry out economic accounting, and to detect whether the liquid level is within the specified range. In order to make the production process go on normally and ensure product quality, output and production safety. Due to its non-negligible importance, the nozzles of the liquid level gauge are usually arranged in pairs, and a pair of liquid level gauge nozzles should ensure that the flange sealing surface is in the same vertical plane, and the verticality tolera...
