Abstract
The utility model provides a double-flange connecting pipeline structure with high sealing performance, which comprises a pipeline, a flange plate, a fastening bolt, a clamping groove and a wave-shaped sealing ring; a flange plate is welded at the end part of the pipeline; the adjacent pipelines are connected by arranging 4-8 fastening bolts at the outer end of the flange plate; a clamping groove is reserved on the butt joint surface of the flange plate; the adjacent flange plates are clamped with wave-shaped sealing rings in the clamping grooves, and the upper surface and the lower surface of each wave-shaped sealing ring are provided with continuous semicircular structures; the diameter of the semicircular structure is equal to the depth of the clamping groove; the thickness of the wave-shaped sealing ring is 4-6 times of the depth of the clamping groove. The utility model discloses a setting of wave seal circle and draw-in groove has both strengthened radial seal intensity, simultaneously again ingenious hidden the seepage route, and then increased substantially flange joint pipeline's sealing performance.
Description
Technical Field
The utility model relates to a pipe connection technical field especially relates to a double flange connection pipeline structure with high leakproofness ability.
Background
The pipeline adopts the traditional double-flange connection under water or is used for oil and gas (natural gas and coal gas) transportation, the phenomenon of poor sealing performance generally exists, and the two main reasons are that firstly, the sealing ring adopting the traditional flange connection is only compressed axially, and the radial sealing performance is poor; and the other is that the traditional flange is adopted to connect the leakage route to be directly exposed in the leakage substance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a two flange joint pipeline structure with high leakproofness ability, through the setting of wave seal circle and draw-in groove, both strengthened radial seal intensity, ingenious while again has hidden the seepage route, and then has increased substantially flange joint pipeline's leakproofness ability.
In order to achieve the above object, the utility model adopts the following technical scheme: a double-flange connecting pipeline structure with high sealing performance comprises a pipeline, a flange plate, fastening bolts, clamping grooves and a wave-shaped sealing ring; a flange plate is welded at the end part of the pipeline; the adjacent pipelines are connected by arranging 4-8 fastening bolts at the outer end of the flange plate; a clamping groove is reserved on the butt joint surface of the flange plate; the adjacent flange plates are clamped with wave-shaped sealing rings in the clamping grooves, and the upper surface and the lower surface of each wave-shaped sealing ring are provided with continuous semicircular structures; the diameter of the semicircular structure is equal to the depth of the clamping groove; the thickness of the wave-shaped sealing ring is 4-6 times of the depth of the clamping groove.
Preferably, the thickness of the flange plate is more than twice of the depth of the clamping groove.
Preferably, the wave-shaped sealing ring is made of silicon rubber, and the width of the wave-shaped sealing ring is 30-60 mm.
Preferably, the depth of the clamping groove is 5-20 mm.
The utility model has the advantages that: the utility model discloses a setting of wave seal circle and draw-in groove has both strengthened radial seal intensity, simultaneously again ingenious hidden the seepage route, and then increased substantially flange joint pipeline's sealing performance.
