Tube (four pass) pressure balance corrugated expansion joint
1. Product Name: curved tube (four links) pressure balanced bellows expansion joint
2. product manufacturer: Jiangsu Yuyang Machinery Co., Ltd.
3. product picture:
4. introduction and features of equipment:
Work pressure: 4.0MPa
Performance characteristics: the front part of the expansion joint has two working bellows, and the rear (blind end) has a balanced bellows. The working bellows absorb transverse displacement from the elbow section, and balance the bellows to absorb axial displacement from the straight pipe section.
5. function description, product application area: the compensator (expansion joint) is commonly used in the pump, tank, compressor, and turbine outlet.
6. technical parameters: working temperature is less than 420 degrees, and fatigue life is 1000 times.
7. working principle: the front end of the curved tube (four pass) pressure balance corrugated expansion joint has two bellows, and the rear end has a balanced bellows. The working bellows absorb the lateral displacement from the end of the pipe and balance the axial displacement of the absorption straight pipe, when the pipe must produce the lateral displacement of the dust. The spherical nut on the rod is rotated around the spherical gasket, and the pull rod is subjected to the internal force, so the compensator (expansion joint) is often used in the pump, tank, compressor and turbine Yamaguchi to reduce the force on the above equipment.
8. supply range and site installation requirements:
(1) curved tube (four links) pressure balanced corrugation expansion joints are often used in pumps, compressors, steam turbines and other load sensitive piping systems. It can rapidly attenuate the vibration of the system pressure wave due to start-up and parking, eliminate the water machine, and absorb vibration and noise, so as to ensure the safe operation of the equipment.
(2) 0.2Mpa series products can be used for medium temperature less than 150 C, full vacuum to 0.2Mpa pressure range, such as steam turbine exhaust pipe of power plant, and 0.6Mpa series products can be used for medium temperature up to 250 C, working pressure up to 0.6Mpa, such as compressor exhaust pipe or petrochemical process pipeline.
(3) the large pull rod is a member that bears the pressure load. When the lateral displacement is absorbed, there must be a certain amount of deflection relative to the bracing plate, and the fastening nut on it should be in place while the spinning is too tight to affect the activity.
