Problems solved by technology

However, when performing hydrostatic testing on pipelines, the number of bolts connected by "flange + flanging" is relatively large. Taking DN100 pipelines as an example, 8 bolts need to be tightened, which is labor-intensive and low-efficiency

Abstract

The invention discloses a high-pressure pipeline fast-connection device based on a flanging edge, and an application method thereof. The high-pressure pipeline fast-connection device based on the flanging edge comprises clamping hoops and wedge block connecting plate assemblies, wherein the wedge block connecting plate assemblies are symmetrically connected onto a pipeline flanging edge in a sleeving way; and the clamping hoops are symmetrically connected onto the wedge block connecting plate assemblies in a sleeving way and are detachably connected with the wedge block connecting plate assemblies. According to the high-pressure pipeline fast-connection device based on the flanging edge, and the application method thereof, the number of bolts for connecting is reduced, the connecting efficiency when a hydrostatic test is carried out on a pipeline is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a fast connection device for high-pressure pipelines based on flanging and an application method thereof. Background technique [0002] At present, the "flange + flanging" connection is an important connection method in pipeline construction, which is easy to use and can withstand relatively high pressure. At present, most of the pipe connections above DN65 in the water cooling system adopt the "flange + flanging" connection method. However, when performing hydrostatic testing on pipelines, the number of bolts connected by "flange + flanging" is relatively large. Taking DN100 pipelines as an example, 8 bolts need to be tightened, which is labor-intensive and low in efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a quick connection device for high-pressure pipelines based on flanging and its use method, reduce ...
