Abstract
A connecting clamping flange structure with a frustum-shaped metal ring seal is characterized by comprising a V-shaped clamp, a male flange joint, a female flange joint and a frustum-shaped metal ring seal gasket, wherein a projecting shoulder of 10 degrees is arranged on the male flange joint, a groove of 10 degrees is arranged on the male flange joint, the frustum-shaped metal ring seal gasket is fixedly mounted through the V-shaped clamp and is deformed under the compression of the male flange joint and the female flange joint, and thus the connecting face of the flanges is sealed. The thickness of the frustum-shaped metal ring seal gasket is 0.4mm-0.8mm. The connecting clamping flange structure with the frustum-shaped metal ring seal has the advantages of being good in sealing effect, light and convenient to install and use. Further, probability of oil leak of the sealing structure is low and maintainability is good when pipelines are under work.
Description
Technical field
The present invention relates to the aeroengine field, a kind of jointing clip flange arrangement with the sealing of cone table shape metal ring is provided especially.
Background technique
Because the relation of intensity, 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.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing line seal structure, a kind of jointing clip flange arrangement with the sealing of cone table shape metal ring is provided especially.
The invention provides a kind of jointing clip flange arrangement with the sealing of cone table shape metal ring, it is characterized in that: the jointing clip flange arrangement of described band cone table shape metal ring sealing comprises V-arrangement clip 1, positive flanged joint 2, cloudy flanged joint 3, cone table shape metal ring sealing gasket 4;
On the sun flanged joint 2 10 ° of convex shoulders are arranged, 10 ° of grooves are arranged on the cloudy flanged joint 3; Install and fix down at V-arrangement clip 1, cone table shape metal ring sealing gasket 4 is realized the sealing of flange junction surface by the extrusion-deformation of positive flanged joint 2, cloudy flanged joint 3.
The one-tenth-value thickness 1/10 of cone table shape metal ring sealing gasket 4 is 0.4mm ~ 0.8mm.
Be applicable to that caliber is in connection and the sealing of φ 25mm with upper pipeline.
Advantage of the present invention:
The jointing clip flange arrangement of band cone table shape metal ring sealing of the present invention, 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.
