Description
Technical field
The utility model is related to the process pipe system of petroleum chemical enterprise S-Zorb gasoline absorbing desulfurization device, specifically applies
A kind of high-temperature and high-pressure wearable in this pipe-line system damages straight-pipe pressure balanced expansion joint.
Background technology
Existing straight-pipe pressure balanced expansion joint, as shown in figure 1, three sections of bellowss all bear internal pressure, work structure ripple
Pipe, balance wave bellows, by the welding between ring flat-plate and adapter, axially aligned, internal pressure thrust pass through ring flat-plate, arm-tie, pull bar,
The transmission of otic placode, plays the effect of balance internal pressure thrust.
Pressure-balancing type structure in shown in Fig. 1, due to two sections of operating wave bellowss and balance wave bellows vertically according to
Secondary arrangement, the entire length of expansion joint is relatively long.In addition, the structure of expansion joint inside lining sleeve can not resist powder grinding medium very well
Abrasion.
Utility model content
