The model of the corrugated compensator does not have a uniform standard. The manufacturer formulates the model according to their own habits, but the name of the corrugated compensator type is the same. The following is a brief introduction to the compensator type of our factory:

8 , damping type expansion joint: professional for shock absorption, the compensator is often used in power equipment, such as the inlet and outlet of the pump (low pressure)
9.
Angular expansion joint: This type of compensator consists of a nozzle, a bellows and a pair of hinges connected to the nozzle. The compensator only absorbs the angular displacement of a single plane. There should be two or three angular compensators in combination, and its hinges have the ability to withstand internal pressure thrust.
10
, universal expansion joint: the compensator has a universal ring , in the circumferential direction of the universal ring has two pairs of mutually perpendicular hinge structure , universal, as the name suggests, it can absorb the angular displacement of any plane . In actual work When used , there should be three or three combinations.
11,
the straight pipe pressure balanced compensator: both ends of the compensator bellows have a work, the middle of a balanced bellows, the compensator to withstand the internal pressure force by the thrust member (large rod or tongue tube), the tube A fixing bracket is required in the middle of the system. The compensator can only absorb axial displacement.
12.
Rotary compensator : Rotary compensator is a self-regulating and non-thrust rotatable casing compensator. It consists of a reducing pipe, an inner pipe, a sealing seat, a packing, a nut, a bolt and a packing gland.
13
, square compensator: square compensator can compensate for large axial displacement, mainly used for low pressure flue gas, air duct.
14
、Dust-free dust pipeline compensator : The non-leakage dust pipeline compensator is suitable for the compensation of thermal expansion and contraction of powdery medium in power plant station boilers such as powder feeding, powder feeding and exhaust gas, and ensures that the dust does not leak.
15
、Rectangular rounded expansion joint: Rectangular rounded expansion joint refers to the new “ CE ” standard and international general product combined with the special condition of China's power plant to develop a new flexible duct of power plant smoke duct. This product is power plant, metallurgy, cement and petrochemical equipment. An important part of the safe operation of the flue gas price pipeline of the system
16,
curved pipe pressure balanced expansion joint: the front portion (channel end) This compensator has two working bellows, to absorb lateral displacement resulting from the bending section; rear (balanced terminals) has a balance bellows pipe, for absorbing axial thrust straight pipe sections at the displacement when the transverse displacement of the bend segment, on the tie rod ball nut is rotated around the large spherical washers, while subjected to a large pressure lever, so that the compensator is used in pumps, tanks At the exit of the compressor and steam turbine, absorb the force generated on the equipment.
