    Functions

    V (1)
    01

    Sealing and Isolation

    Its main function is to form a sealing barrier between mechanical parts to prevent the leakage of fluid media between different parts or regions, ensuring the sealing and integrity of the system.
    V (2)
    02

    Displacement Compensation

    It can compensate for the displacement and deformation between parts caused by factors such as mechanical movement, thermal expansion and contraction within a certain range, and maintain the sealing effect.
    V (3)
    03

    Buffering and Shock Absorbing

    The elasticity of rubber enables it to absorb and buffer the vibrations and impact forces generated by mechanical movement, reducing the damage to the sealing parts and the entire system.

    Application Scenarios

    V (7)
    04

    Pipeline Connection

    At the interfaces of pipelines, it is used to seal the fluid inside the pipeline to prevent leakage, and is suitable for pipelines transporting various media such as water, oil, and gas.
    V (8)
    05

    Water Lifting & Dividing Devices

    It has good corrosion resistance and abrasion resistance, can work stably in the long-term drinking water supply environment, and reduces the frequency of maintenance and replacement. It can precisely control the distribution of water flow to avoid unnecessary waste of water resources. Through a reasonable design and sealing structure, it can prevent the water from different water use points from flowing back into the main pipeline, avoiding cross-contamination of water quality.
