Abstract
The utility model provides a heavy caliber low condensation wave expansion joint, which mainly resolves the problem that a rubber expansion joint on a circulating water communication pipeline of a power plant condenser has severe disadvantages of being prone to age, unreliable and high in maintenance cost and the like. The heavy caliber low condensation wave expansion joint comprises a backing ring, a flange, a pull rod assembly and a bellows. The caliber of the expansion joint is 2500 mm to 2700 mm, and the pitch of waves is 25 mm to 27mm. The heavy caliber low condensation wave expansion joint can be applied to the circulating water communication pipeline of the power plant condenser to replace the aging and unreliable rubber expansion joint and is low in price.
Description
Technical field
The utility model relates to a kind of bellows expansion joint, is a kind of low condensation wave expansion joint of heavy caliber that is used on the plant condenser circulating water connecting pipe specifically.
Background technique
On plant condenser circulating water connecting pipe, select for use expensive rubber expansion joint usually as being flexible coupling.But rubber expansion joint exist be prone to aging, reliability is not high and deadly defect such as maintenance cost height.Vapour condenser circulating water connecting pipe bore is bigger, is generally more than the 1200mm, and very short because of the expansion joint length of installation, the rigidity of bellows again can not be excessive, and this just requires the pitch of waves of bellows must be little; Because make things convenient for bolt to connect again and install, so require the wave height of bellows must be low.But the shape and the structure of common metal bellows can't satisfy above-mentioned requirements simultaneously at present, so also can't directly be applied on the plant condenser circulating water connecting pipe.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model is to provide a kind of heavy caliber to hang down the condensation wave expansion joint.
The purpose of the utility model is achieved in that its bore is that the internal diameter of bellows is 1200-3500mm, and its pitch of waves is 25-27mm.
Compared with prior art, the beneficial effect of the utility model is: it can be applied on the plant condenser circulating water connecting pipe, is prone to aging and the not high rubber expansion joint of reliability to replace, and low price.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment
It comprises gasket ring 1, flange 2, rod assembly 3 and bellows 4, and its bore d is 2640mm, and its pitch of waves c is 26mm.When experiment showed, its operation, axial displacement is 30mm, and radial displacement is 15-20mm, is in service reliably at present.Behind the utility model instead of rubber expansion joint, fatigue life is long and controlled, and reliability is high, and operation expense is low.
Claims (2)
1. a heavy caliber hangs down the condensation wave expansion joint, and it comprises gasket ring, flange, rod assembly and bellows, it is characterized in that: its bore is 1200-3500mm, and its pitch of waves is 25-27mm.
2. according to the low condensation wave expansion joint of the described heavy caliber of claim 1, it is characterized in that: said bore is 2640mm, and the pitch of waves is 26mm.
