Embodiment
Embodiment one：
As shown in Figure 1 to Figure 4, a kind of double-deck alarm high-pressure draw bar type FlexbleJoint, including left adapter 10 and right adapter 20, it is left
The outer end of adapter is provided with left flange 11, and the outer end of right adapter is provided with right flange 21.
One left bellows 30 of left adapter connection, one right bellows 40 of right adapter connection, left bellows and right bellows
Interconnected by a middle adapter 50.
State left flange and the right flange is connected by pull bar 60.In the present embodiment, pull bar both ends are provided with screw rod, left flange
Connected with right flange by 12 pull bars along circumference of flange etc. point distribution.Pull bar both ends are provided with screw rod 61 and nut 63, Zuo Fa
Connected between the nut of blue and right flange and pull bar by the conical surface and taper faced washer 61.
Left bellows and right bellows are provided with the double-ply bellows of internal layer bellows and outer layer bellows.As shown in figure 3,
Left bellows is provided with internal layer bellows 31 and outer layer bellows 32.
Outer layer bellows and internal layer bellows weld at both ends（Such as Fig. 3, shown in C）, closing connection is formed, makes internal layer ripple
Closing space is formed between joint face between pipe and outer layer bellows.The inspection of internal layer bellows is communicated with outer layer bellows
Test tube 70, the closing space between detection pipe connection internal layer bellows and outer layer bellows.In the present embodiment, left bellows and the right side
The both sides of bellows are respectively equipped with a detection pipe, and two detection pipes on the left of left bellows and right bellows pass through metal hose
A detection mouth 71 is connected, two detection pipes on the right side of left bellows and right bellows pass through connection by metal hose another detection
Mouth 72.The extraction location of detection pipe and the position stagger setting of pull bar.
Reinforcing ring is provided with the wave groove outside left bellows and right bellows, the internal diameter of reinforcing ring corresponds to left ripple
The internal diameter of pipe and right bellows outer corrugations groove.
An end reinforcing ring 81 is respectively equipped with the both ends of left bellows and right bellows, in the left bellows and right ripple
An interior reinforcing ring 82 is respectively equipped with each outer corrugations groove of line pipe.
In the present embodiment, the core parts of FlexbleJoint are bellows, pull bar and pipe connecting flange structure.Its function is energy
The radial displacement of pipeline is enough compensated, that is, can allow to produce a certain amount of parallel misalignment movement between two flanges.
The compensator of the present embodiment requires that bearing capacity is very high, so employing reinforcing ring armouring ring structure, this structure
The existing effect for strengthening bellows, also balances the effect of bellows deformation.
Because the high pressure in pipeline, internal pressure thrust caused by bellows is very high, and very high, institute is required to the tensile capacity of pull bar
To employ 12 pull bars.Flange is also thickeied.
The FlexbleJoint of the present embodiment is used in the pipeline of conveying toxic gas, to product reliability requirement very
It is high, it is impossible to have any leakage.So in design, it is ensured that singel-ply bellows meets intensity requirement, but uses double-deck ripple simultaneously
Line pipe, improve reliability.Detection pipe is provided with bellows both ends, i.e., is punched in outer layer bellows, and welds detection pipe, is detected
Pipe connects ann test device, once internal layer bellows is revealed, detector can pass through internal layer bellows and outer layer bellows
Between gap detect gas leakage, and and alarm.Now outer layer bellows can also normal work, avoid pipeline
Gas leaks, the chance provided for on-call maintenance, it is ensured that poisonous, hazardous gas the pipe safety operation of conveying.
