Spacing distance between the right-hand member of left end pipe and the left end of right-hand member pipe is expansion clearance G.
Provided with first member plate 7 is fixedly connected with left end pipe on the left end pipe, first member plate passes through reinforcement 8 and the left end
Pipe is welded.Provided with the right end plate 9 being slidably matched with right-hand member pipe on the right-hand member pipe.The first member plate passes through pull bar with right end plate
10 are fixedly connected.The present embodiment is altogether provided with four pull bars, along compensator circumference etc. point distribution.Pull bar passes through nut 11 and a left side
End plate and right end plate are fixed.
The left work bellows is the external pressure bellows being enclosed on the left end pipe, the right-hand member 1a of the left end pipe and institute
The right-hand member connection of left work bellows is stated, the right work bellows is the external pressure bellows being enclosed on the right-hand member pipe, described
Right-hand member pipe is connected in left end 2a with the left end of right work bellows, and right-hand member and the right end plate of the right work bellows connect
Connect；The first outer tube 12, the left end of the left work bellows are cased with outside the left work bellows and right work bellows
The left end of 3a and right work bellows connects first outer tube respectively；It is described balance bellows-sheathed first outer tube it
Outside, the right-hand member 5a of the balance bellows is connected with the right-hand member of first outer tube；The is cased with outside the balance bellows
Two outer tubes 13, the right-hand member of second outer tube connects the right end plate, and the left end of second outer tube connects the balance ripple
The left end 5b of pipe.
Hole 14, the left work bellows, the right side are communicated between the left end of the left end of right-hand member pipe and right work bellows
Work bellows, balance bellows constitute the closing connected with the expansion clearance with the first outer tube, the second outer tube and right end plate
Space.
First outer tube is slidably matched in left end with the left end pipe, and second outer tube is outside left end and described first
Pipe is slidably matched.
First outer tube be provided with connect with the closing space first purging flange 14, second outer tube provided with
Second purging flange 15 of the closing space connection, the right end plate is provided with the purging exhaust connected with the closing space

" left side " and " right side " in the present embodiment is relative structuring concept, can mutually replace, be not meant to related knot
Structure feature is definitely located at left side or right side.
The enclosed type band of the present embodiment purges the complete balanced compensated device of external pressure and is applied to conveying solid substance little particle medium or gas
, narrow space and needing absorbed in the pipeline of larger thermal walking.
The effective area Sp of balance bellows is 2 times of work bellows effective area Sg.
Pressure medium in pipeline is P, and work bellows is Fg, Fg=P × Sg due to the thrust that pressure medium is produced.
Balance bellows is Fp, Fp=P × Sp=2Fg due to the thrust that pressure medium is produced；
The pressure thrust produced due to pressure passes through the transmission of the big pull bar of rigid member and outer tube, two work bellows productions
The pressure thrust Fp that raw pressure thrust 2Fg is just produced with a balance bellows balances each other.
Left work bellows, right work bellows, balance bellows are external-compression type bellows, will not produce post unstability and show
As.Two work bellowss are arranged on the inside of balance bellows, reduce installation length.Therefore in the space of restriction, carry
High compensation rate, reduces installation length, while also improving security.
When pipeline temperature rise, left end pipe drives left work bellows is mobile to be to the right stretched；Left end pipe sidesway to the right simultaneously
It is dynamic that first member plate can be driven to drive right work bellows is mobile to be to the right stretched by pull bar, and the second outer tube can be driven to the right
Side is moved, so as to drive balance bellows, also movement is compressed to the right.Stretching and compression are equivalent elongation.
Because work bellows and balance bellows are external-compression type, the inner pressed corrugated expansion joint compared with common form is carried
The high ability for absorbing thermal walking, while being provided with outer tube outside bellows, it is to avoid bellows is exposed may to be sent out outside
The raw damaged condition such as collide with occurs.
Due to being provided with purging flange, compensator inside can be purged by purging flange in maintenance, simultaneously
Plug is opened, the medium or finely ground particle substance of compensator internal residual can be cleaned up, prevents from influenceing the use of bellows,
The service life of compensator is improved simultaneously.
