Retrieval finds, application number is that 200720200509.6 Chinese patent application discloses a kind of rotary flange, comprises upper flange, lower flange, pressure-bearing body and locking ring; Pressure-bearing body and lower flange are fixedly installed togather, outer upper at the pressure-bearing body is set with upper flange, between pressure-bearing body and upper flange, seal ring is installed, in the external side of pressure-bearing boss is arranged, on the boss of pressure-bearing body, be set with locking ring, the upper end of locking ring and the lower end of upper flange link together, and the card platform of locking ring lower end can be stuck in the bottom of boss, and this flange makes upper and lower flange can produce relative angular displacement.In addition, application number is that 200920300165.5 Chinese patent discloses a kind of rotatable flanged connecting structure, include outer tube and interior pipe, the external diameter of interior pipe and the internal diameter of outer tube are suitable, interior pipe box is gone in the outer tube, offer a circular groove on the tube wall in the outside of interior pipe, outer tube wall and the corresponding position of interior pipe circular groove also are provided with circular groove, outer tube wall is provided with a through hole that is communicated with the outer tube circular groove, between pipe circular groove and the outer tube circular groove outer tube is fixedlyed connected with interior pipe in a plurality of fixture blocks are stuck in by this through hole.After installing between outer tube and the interior pipe, need not dismounting between the two and can realize 360 ° of rotations.
Facts have proved that the rotary flange of above-mentioned existing structure all is difficult to satisfy seal request for the discharge pressure fluid.
Summary of the invention
The objective of the invention is to:, propose a kind of rotary flange that not only has the rotation compensation function and can satisfy pressure fluid conveying seal request conscientiously at the problem that above-mentioned prior art exists.
In order to reach above purpose, rotary flange of the present invention comprises isometrical first adapter and second adapter that port is relative; The described first adapter cylindrical sealing is fixed with the fastening flange that end face exceeds the first adapter port, and described second takes over the cylindrical sealing is fixed with the back-up ring that end face exceeds the second adapter port; The end face of the contiguous described back-up ring of described fastening flange is shaped on the depression that diameter and back-up ring cylindrical match, and the end face that described back-up ring deviates from described fastening flange has annular groove; After the assembling, described fastening flange is connected by fastening piece with the lap joint flange that is enclosed within the second adapter cylindrical, and the end face of the contiguous fastening flange of described lap joint flange contacts with the ball in being placed in described back-up ring end face annular groove; Described back-up ring imbeds the depression of described fastening flange, on the gasket seal of pressure holding in embedding depression; Circle had the seal ring of annular groove in described first adapter and second was taken over and is equipped with between the relative port, and the thickness of described seal ring is taken over described first and the spacing of the relative port of second adapter matches.
Like this, rotate relatively when not only two adapters can be subjected to Buckling stress, thereby the stress deformation of compensation conduit, and the cognition of the pressure flow in the pipeline acts on annular groove in the seal ring, seal ring is produced be close to circle and two trend of taking over port in fastening flange and the back-up ring, pressure is big more, and it is remarkable more to be close to trend, thereby plays reliable seal action.
The present invention further improves, and described first adapter is fixed with gasket ring respectively with the interior circle of the second relative port of taking over; The gap less than annular groove width in the described seal ring is left in the relative termination of described two gasket rings.Like this, can prevent that not only seal ring from getting loose, and can make seal ring when being subjected to hydrodynamic pressure, produce towards helping strengthening the trend that the sealing direction expands.
The present invention further improves, and described first adapter and second external diameter of taking over and the internal diameter of described fastening flange and back-up ring and seal washer match, and equate with the external diameter of described seal ring.
Description of drawings
Accompanying drawing 1 is the structural representation of a preferred embodiment of the invention.
Embodiment
The rotary flange of present embodiment comprises isometrical first adapter, 1 and second adapter 8 that port is relative as shown in Figure 1.First takes over the cylindrical seal welding is fixed with end face and exceeds first fastening flange 2, the second of taking over port and take over the cylindrical seal weldings and be fixed with end face and exceed second back-up ring 5 of taking over port.The end face of the contiguous back-up rings 5 of fastening flange 2 is shaped on the depression that diameter and back-up ring cylindrical match, and the end face that back-up ring 5 deviates from fastening flange 2 has annular groove.After the assembling, fastening flange 2 is connected by clamping bolt 10 with the lap joint flange 7 that is enclosed within second adapter, 8 cylindricals.The end face of lap joint flange 7 contiguous fastening flanges 2 contacts with the ball 6 in being placed in back-up ring end face annular groove, forms the structure of similar end face bearing.Back-up ring 5 imbeds the depression of fastening flange 2, on the gasket seal 4 of pressure holding in embedding depression.Circle had the seal ring 3 of circular cross-section annular groove in first adapter 1 and second was taken over and is equipped with between the 8 relative ports.Seal ring 3 materials are the peroxidating fluorine rubber of heatproof and media-resistant corrosion, and thickness and first is taken over 1 and second spacing of taking over 8 relative ports and matched.In order to prevent that seal ring from getting loose, the gap less than annular groove width in the seal ring is left in the relative termination that the first interior circle of relative port of taking over 1 and second adapter 8 is fixed with stainless steel gasket ring 9, two gasket rings respectively.First adapter and second external diameter of taking over and the internal diameter of described fastening flange and back-up ring and seal washer match, and equate with the external diameter of seal ring 3.
During work, Sealing 3 under the pressure medium effect, is close to the formation sealing with the end face of adapter 1 and adapter 8 and the internal circular surfaces of flange 2 and back-up ring 5 in pipeline.The ball installed in back-up ring 5 grooves 6 becomes rolling friction, the frictional force in the time of can effectively reducing rotation with sliding friction.Gasket seal 4 materials between fastening flange 2 and the back-up ring 5 are graphite, provide protection against wear.
Advantage of the present invention mainly contains: 1) the rotatable connection by flange has guaranteed compensating action; 2) gasket seal and seal ring 3 organically combine, and have improved the reliability of sealing; 3) ball in back-up ring 5 grooves 6 becomes rolling friction with sliding friction, and the frictional force that effectively reduces has been improved the verticity of product.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
