Abstract
The utility model discloses a metal ring sealing connection hoop flange structure with a cylindrical ring. The metal ring sealing connection hoop flange structure with the cylindrical ring is characterized by comprising a V-shaped hoop, a positive flange joint, a negative flange joint and a metal ring sealing gasket with the cylindrical ring. A ring protrusion shoulder is arranged on the positive flange joint, and a ring groove is formed in the negative flange joint. Under installing and fixing of the V-shaped hook, the metal ring sealing gasket with the cylindrical ring achieves sealing of a flange connection face by squeezing and deforming of the positive flange joint and the negative flange joint. The thickness delta of the metal ring sealing gasket with the cylindrical ring is 0.6mm-0.9mm. The metal ring sealing connection hoop flange structure with the cylindrical ring has the advantages that compared with connection of a traditional flange disc, connected stress is even, and the connection hoop flange structure is beneficial to sealing, light in weight, and convenient to install and use. In working of a pipeline, probability of oil leakage of the sealing structure is low, and maintainability is good.
Description
Technical field
The present invention relates to the aeroengine field, a kind of metal ring with tubular ring clip flange arrangement that is tightly connected is provided especially.
Background technique
The system that the V-arrangement clip connected is suitable for is the lower system of pressure, is not suitable for high-pressure systems such as hydraulic pressure and cold air and uses.But gas system generally all allows certain air leakage, and less than the liquid system height, so the V-arrangement clip connected can improve suitable temperature range by adopting special elevated-temperature seal part to the requirement of sealing.
Because pipe diameter is big, if adopt the mode of screw thread butt joint, the processing of screw thread will be a difficult problem, and necessary twisting size also can to use physical dimension and weight to increase a lot, so, connect for large diameter pipeline, adopt the end face ways of connecting more.The V-arrangement clip belongs to end face and connects, and is to connect development and next by traditional flange plate.The intensity of V-arrangement clip connected connects low than flange plate, but still high more a lot of than the intensity of conduit itself, does not therefore influence use.And the stressed of V-arrangement clip connected connects evenly than the conventional flange dish, and be favourable to sealing, and in light weight, easy to install.Therefore in the aircraft large pipeline connects, replaced flange plate substantially and be formed by connecting and be main mode.
Though the V-arrangement clip connected designs for gas system, do not repel in liquid systems such as fuel oil, lubricating oil and use, in fact as the example that uses the V-arrangement clip in liquid system is arranged on the civil aircrafts such as Boeing, Air Passenger.For further increasing the V-arrangement clip in the supravasal application of motor major diameter, except bleed air system, therefore the application of emphasis on liquid system must take into full account the sealing configuration of required employing.
At above present situation, need the jointing clip flange arrangement of a kind of novel aeroengine band metal ring sealing of design, in the assembling that improves pipeline, guarantee the sealing reliability of pipeline.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing line seal structure, a kind of metal ring with tubular ring clip flange arrangement that is tightly connected is provided especially.
The invention provides a kind of metal ring with tubular ring clip flange arrangement that is tightly connected, it is characterized in that: the metal ring of the described band tubular ring clip flange arrangement that is tightly connected comprises the metal ring sealing gasket 4 of V-arrangement clip 1, positive flanged joint 2, cloudy flanged joint 3, band tubular ring;
On the sun flanged joint 2 annular convex shoulder is arranged, on the cloudy flanged joint 3 annular groove is arranged; Install and fix down at V-arrangement clip 1, the metal ring sealing gasket 4 of band tubular ring is realized the sealing of flange junction surface by the extrusion-deformation of positive flanged joint 2, cloudy flanged joint 3.
The thickness δ of the metal ring sealing gasket 4 of band tubular ring is 0.6mm ~ 0.9mm.
Be applicable to that caliber is in connection and the sealing of φ 24mm with upper pipeline.
Advantage of the present invention:
The metal ring of the band tubular ring of the present invention clip flange arrangement that is tightly connected, the stressed of connection connects evenly than the conventional flange dish, and be favourable to sealing, and in light weight, easy to install.During pipeline work, the probability of sealing configuration generation leakage of oil is low, and maintainability is good.
