Now it seems that these problems are no longer difficult. The fork type pneumatic valve takes us into a new world of data control. He can stay anywhere between 0-90 ° to within 0.1mm. This has opened up a new world. In addition, its size is very small and its consumption is very small. Compared with the rack type, its space consumption is reduced by 30% and its air source is saved by 40%. This not only saves raw materials but also reduces the space occupied. At the same time, its service life has also increased to more than 1 million times.

Do you understand the installation skills of metal corrugated compensator
The waveform of metal corrugated compensator can be divided into "U" shape and "Ω" shape. The "Ω" shaped bellows can accept high pressure, but only small axial displacement; On the contrary, the U-shaped bellows can accept larger displacement but only smaller pressure under the same wall thickness.
The device of metal corrugated compensator is exquisite:
1. The metal corrugated compensator is a special pipeline element, which is complex and demanding. It needs to calculate the pipeline thrust and the force on the injection fixed support, so it cannot be installed without authorization, or it will cause an accident. Therefore, the device has pipeline construction drawings and detailed configuration of pipeline supports provided by the professional design department. And request to stop by referring to the compensator device instruction.
2. Compensator with flow direction request shall be stopped according to the request of medium flow direction arrow.
3. In order to keep the bellows in good working condition, the deformation of the compensator, including axial, transverse and change, cannot be used to adjust the position error of the pipe system.
4. Before the device, the corrugated pipe and foreign matters in the pipe shall be cleaned to ensure the normal movement of the corrugated pipe.
5. When purchasing, do not rely only on the model or code, but provide data to the metal compensator manufacturer, and the metal compensator manufacturer will design and consume the data to ensure the service life or quality.
6. The bellows used for the compensator is formed with thin-walled stainless steel plate, so during transportation, lifting and welding, care should be taken not to damage the bellows due to knocking, scratching, arc striking, welding spatter and other reasons.
7. Before system operation, the manufacturer of small pull rod common metal compensator does not propose to remove it, but after the end of pressurization, loosen the inner nut according to the compensation amount.
8. The pipeline of the metal corrugated compensator is properly guided and fixed to make the compensator work, so the setting of the guide and fixed support is strictly in accordance with the relevant technical materials of the design department.
Effective area: an equivalent area, (Ae=(π Dm2)/4 mm2 Dm corrugated pipe uniform diameter).
Fatigue life: the number of small cycles that the bellows can work normally under normal working conditions.
The important parts are the important guarantee to ensure the normal operation of the pipe contraction joint. These parts should be properly selected according to different application conditions.
Lining cylinder: the cylinder used to reduce the contact between the inner wall of the corrugated pipe of the metal compensator contraction joint and the moving medium passing through it, also called the inner sleeve or the guide cylinder. The information of the inner liner can be the same as or different from that of the bellows.
Limiting rod: a part set on the metal compensator contraction joint assembly, usually made of a rod or bar, which is mainly used to limit the movement range (axial, transverse, angular) of the bellows under normal working conditions. When the main fixed support is damaged, this part can prevent the bellows from over stretching and tightening, At the same time, it can also control all internal pressure loads and dynamic loads caused by support destruction.
