Flowmeter flange dismounting device and using method

Abstract

The invention relates to a flowmeter flange dismounting device which comprises a dismounting module used for dismounting rusted fixing bolts, a flowmeter frame installed on a flowmeter flange and a pipeline flange frame installed on a conveying pipeline flange, and pipeline flowmeters used in a steel plant are different in size and form. However, most pipelines are connected through flanges, but fixing bolts of the flanges are prone to corrosion and rusting due to the fact that the field environment is severe, and when the pipeline flow meters need to be maintained or replaced due to faults, the flanges of the pipeline flow meters and the fixing bolts of the pipeline flanges cannot be disassembled normally due to rusting. In the prior art, a rusty fixing bolt in a flange needs to be fused through air welding, but the field environment belongs to a gas area, large potential safety hazards exist in fire operation, the efficiency of manually disassembling the rusty fixing bolt is low, and production of enterprises can be greatly influenced. Therefore, a device capable of guaranteeing safety and rapidly disassembling the rusted fixing bolt needs to be developed.

Description

technical field [0001] The invention relates to the technical field of pipeline device disassembly, and more particularly, to a pipeline flowmeter flange disassembly device and a method for using the same. Background technique [0002] The pipeline flowmeters used in steelmaking plants vary in size and form, but most of them use flanges to connect with pipelines. However, due to the harsh site environment, the flange fixing bolts are easily corroded and rusted. When the flowmeter needs to be repaired or replaced due to a fault, it is often impossible to disassemble normally due to the rust of the fixing bolts of the pipeline flowmeter flange and the pipeline flange. It is necessary to use wind welding to melt the rusted fixing bolts in the flange. In the gas area, there is a great potential safety hazard in hot work. The relatively safe way is to let the staff manually disassemble the rusted fixing bolts. Manually disassembling the rusted fixing bolts is time-consuming and l...

Problems solved by technology

[0002] Pipeline flowmeters used in steelworks vary in size and in various forms, but most of them are connected to pipelines by using flanges. However, due to the harsh environment on site, the fixing bolts of the flanges are easily corroded and rusted. When the flowmeter needs to be repaired or replaced due to failure, it is often impossible to disassemble normally because the fixing bolts of the pipeline flowmeter flange and the pipeline flange are rusted. It is necessary to use wind welding to melt the rusted fixing bolts in the flange, but the site environment belongs to In the gas area, hot work has great potential safety hazards. The relatively safe way is to let the staff manually remove the rusted fixing bolts. Manual removal of the rusted fixing bolts is time-consuming and laborious. The efficiency is low. The normal production of the enterprise Therefore, it is necessary to develop a device that can ensure safety and quickly disassemble the rusty fixing bolts.
