Valve bellowsIt is an important supporting component connecting valves and pipelines. It has the effects of buffering, shock absorption, and noise reduction. It is widely used in petrochemical, chemical, electric power, water treatment and other fields. The direct connection method is to connect the two ends of the bellows directly with the valve and pipeline interface through the flange, which is a widely used way. This method is simple to install, easy to operate, suitable for some occasions without too high precision requirements.

The suspension method is to fix the two ends of the bellows on the boom and connect directly with the interface of the valve and the pipeline. This method is suitable for occasions where the location of the pipeline is relatively fixed, but the surrounding environment is more complex and the construction is more difficult. The method of supporting and lifting is to set the support and hanger around the pipeline and connect the two ends of the bellows with the valve and the pipeline through the flange. This method is suitable for occasions where the length of the pipeline is long, the deformation is large, and the number of brackets is large, which can greatly improve the stability of the pipeline.

The hard cylinder insertion method is to insert a section of the corrugated pipe into the joint of the valve or pipeline, and the other end is connected to the pipeline through the flange. The application range of this method is relatively narrow, and it is suitable for some occasions with large bending or squeezing pressure. The corrugated pipe section adjustment method is to adjust the section thickening at the corrugated pipe connection to improve the compression and tensile capacity of the corrugated pipe. This method is suitable for some occasions that withstand high pressure, high temperature and corrosive media.

Bellows valves are often affected by vibration in industrial production. However, the use of bellows circumvents this problem, and its shock resistance is very good. The bellows can better resist external shock and vibration, and improve the service life. In industrial production, will often encounter high temperature and strong acid, alkali and other corrosive environment, so the valve bellows not only requires mechanical strength, but also has strong corrosion resistance. The use of bellows valves will be able to meet this demand.

The bellows can always maintain the sealed state of the liquid during the opening and closing of the valve, and will not cause leakage problems. The bellows has good resilience, so that the liquid can flow smoothly. Because of its particularity, the construction adjustment can be completed by adjusting the corrugated length, angle and position. In this way, the error rate of the valve is greatly reduced and the accuracy of the valve is improved. In the installation process, only the corrugated pipe and the flange can be welded, simple and convenient, and the time is short. Thus, the valve production efficiency is improved. In industrial production, the stability of the fluid state can always be maintained, the irregular flow of liquid can be avoided, and the stability and continuity of the process can be enhanced.

Water pump bellows is a kind of valve bellows, its use is mainly to meet the requirements of the pump. The bellows of the water pump can be used as a flexible connecting piece, and can also handle the medium under high temperature and high pressure, and its bellows pressure bearing capacity is very high.

As one of the important parts in the industrial field, the valve bellows has many advantages and can enhance the stability and sustainability of industrial production. The water pump bellows can meet more advanced requirements and become an important component with large pressure bearing capacity and long service life.
