The novel vacuum flange is used for connecting two pipe stocks for the aviation and is mainly divided into two parts, namely the low-step plate body and the high-step plate body, one side of the low-step plate body is used for connecting the pipe stocks, and one side of the high-step plate body is used for being connected with another flange.
Description
Technical field
The present invention relates to tube connection piece field, be specifically related to a kind of novel aviation vacuum flange.
Background technique
Flange (Flange), the again blue flange disk of call or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Flange joint or flanged joint, refer to and be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Piping flange means the flange of pipe arrangement in tube equipment, is used in import and export flange equipment meaning equipment.Perforation on flange, bolt makes two flanges be close to, and uses liner containment between flange.Flange divides the flange that is threaded, welded flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use an acting flange, and four kilograms with the use welded flange of upward pressure.Add sealing gasket between two panels flange plate, then use bolton.The flange thickness of different pressures is different, and the bolt that they use is also different.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide the novel aviation vacuum flange that a kind of tightness is very high.
The technical problem that the present invention solves can realize by the following technical solutions: a kind of novel aviation vacuum flange, comprise flange plate, wherein said flange plate is ladder-type, the centre of flange plate is provided with attachment hole, the left end of attachment hole is provided with screw thread, the right-hand member of attachment hole is provided with circular hole, flange plate is made up of low order dish and high-order dish, low order dish is positioned at the left end of flange plate, the left side of low order dish is provided with seal ring, seal ring is made up of two half-turns, the other end of half-turn is provided with retaining ring, high-order dish is provided with annular equally distributed through hole, the right side of high-order dish is provided with soft sealing.
Preferably, hinged between described two half-turns, the lower surface of half-turn is provided with pyrometric cone block.
Preferably, the outer surface of described soft sealing is sawtooth pattern.
Preferably, be inclined-plane between the inherent described screw thread of described attachment hole and described circular hole.
Preferably, be provided with in flakes between described retaining ring and described low order dish, be positioned in flakes on the outer side surface of low order dish.
Beneficial effect is: this flange is the ultravacuum flange of aviation, for connecting the two pieces tubing of aviation, this flange is mainly divided into two-part, is respectively low order dish and high-order dish, wherein low order dish side is for connecting tubing, and high-order dish side is then for connecting another flange.Screw thread is provided with in low order dish, can prevent tubing from dropping after being connected with tubing, and be also provided with seal ring in the outside of low order dish, seal ring is made up of two half-turns and a retaining ring, retaining ring can fix tubing by fixing for two half-turns, and is also provided with pyrometric cone block inside half-turn, strengthens the sealing between seal ring and flange, namely there is fixing effect, also play the effect of sealing.Retaining ring, with being connected on low order dish in flakes, both can not having hampered the fixing of retaining ring and can also prevent retaining ring from dropping.In addition, also circular hole is provided with in one end of high-order dish, can placement positioning ring and pad in circular hole, and be also provided with zigzag soft sealing on the right side of high-order dish, when connecting two flanges with bolt because the mutual occlusion of sawtooth can sealing between reinforcing flange and flange.
