Description
Technical field
The utility model relates to mechanical fastener technical field, particularly relates to a kind of steady type flange apparatus.
Background technique
Flange makes pipe and the mutual flange of pipe be make pipe and the interconnective part of pipe, and in pipeline connection area, flange is played vital position by general use.The kind of flange has a variety of, butt welding welded flange has been widely used in the industry owing to having the advantages such as not yielding, good seal, the pipeline of the pipeline that be applicable to this flange pressure or temperature fluctuate widely or high temperature, high pressure and low temperature, also for carrying the pipeline of expensive, inflammable, explosive medium.In present many chemical pipelines, all there is the operating mode of high pressure, under the impact of strong pressure, the life-span of a lot of flange is all very of short duration, and the infringement of flange directly will have influence on whole work system, in some corrosion-prone operating modes, end face of flange can lose efficacy because of the erosion of corrosion materials.At present, for the research of flange compression resistance, be connected to pipe end meaning power all on the material and preparation process of flange, but ignore structural design to the impact of compression resistance.The design of its structure is on the impact of compression resistance.Therefore, therefore intensity, the compression resistance exigence of flange improve, and develop a kind of pressure-proof flange with anti-high pressure.
Simultaneously when flange matches between two, for being all plane-plane contact between two component flanged plates, often there is eyelet deviation, when closing up pairing, often causing bias, sliding phenomenon, increase the difficulty of installing and closing up.
In addition traditional flange plate adopts pad as black box, there is screw when connecting and cross locking and easily cause the rotten tooth of silk mouth locked during use; Heavily tear flange open in overhaul of the equipments or unloading process, gasket seal easily tears, and long-time uses that pad is aging easily causes poorly sealed leaking.
And flange plate makes pipe and the interconnective part of pipe, be connected to pipe end, be generally paired use, Flange joint is easy to use, can bear larger pressure, and in industrial pipeline, the use of Flange joint is very extensive.The flange plate connected, after Long-Time Service, there will be loosening phenomenon, improves flange plate fixed effect, just can prevent flange plate from loosening, and how to improve the Main Means that flange plate fixed effect has also become to prevent flange plate from loosening.
