为了使得橡胶接头达到较高的使用寿命以及耐负压,通常在制造时会加衬导流筒,这样既起到了介质导向的作用,还起到了防止波纹免受冲击力的损坏 Guide: In order to achieve a high service life of the rubber joint and resistance to negative pressure, the baffle is usually lined during manufacture, which not only plays a role of media guidance, but also prevents ripples from being damaged by impact.

In order to make the rubber joints have a higher service life and resistance to negative pressure, the baffle is usually lined during manufacture. This not only plays a role of media guidance, but also prevents ripples from being damaged by impact forces. However, when When the design and installation of the deflector is unreasonable, the pace of damage to the rubber joint will also be accelerated. Today, let's explore the reasons for the damage of the deflector!
The main role of installing a deflector is to keep the pipeline medium flowing in a balanced manner, and not to allow the medium to directly impact or erode the bellows. However, after the baffle is installed, the medium will directly impact the baffle. When the design of the baffle structure is not reasonable, it may cause the baffle to fall off completely or partly. The overall shedding mainly occurs under the condition of high pipeline flow velocity and vibration. The rubber joint installed with the deflector has a sudden decrease in the end face of the overcurrent and an increase in the flow velocity of the medium. At this time, the weld at the fixed end of the deflector will be violently impacted. When the strength of the weld is insufficient or there is stress concentration, The mouth is disengaged, and the baffle is blown off as a whole. Part of the shedding mainly occurs when the material of the deflector is stainless steel and thin (1-2MM). Due to the poor toughness of the material, the movable end of the deflector is severely washed away by the airflow, causing high-frequency vibration, and finally leading to tearing and partial occurrence. Fall off. The deflector after falling off will flow forward along with the medium, which will seriously threaten other facilities in the pipeline, such as various temperature and pressure acquisition equipment. If the bellows is installed at the front end of the steam turbine, the broken deflector fragments enter the steam turbine, which will break the turbine blades and cause serious consequences. Sometimes the torn tip of the baffle can puncture the bellows and cause the bellows to fail.
When using a rubber joint lined with a deflector, the above phenomenon must be avoided. Only in this way will the rubber joint play a normal role, and at the same time, it will avoid unnecessary troubles to the engineering installation.
