Advantages and disadvantages of resilient sealed gate valve

Release time:

Jun 30,2024

The construction of the resilient sealed gate valve is composed of valve body, valve cover, gate, gland, stem, handwheel, and sealing gasket. As a common manual switch type valve on the pipeline, the resilient sealed gate valve is mainly used in waterworks, sewage pipes, municipal drainage projects, fire-fighting pipeline projects, as well as industrial pipelines on slightly non-corrosive liquids and gases.

   The construction of the resilient sealed gate valve is composed of valve body, valve cover, gate, gland, stem, handwheel, and sealing gasket. As a common manual switch type valve on the pipeline, the resilient sealed gate valve is mainly used in waterworks, sewage pipes, municipal drainage projects, fire-fighting pipeline projects, as well as industrial pipelines on slightly non-corrosive liquids and gases.

                                                            

    一、 Advantages of resilient sealed gate valve

   1、good sealing performance: resilient sealed gate valve using elastic material as a sealing vice, can effectively prevent media leakage. The elastic sealing material can closely fit with the valve seat sealing surface, forming a good sealing effect.

    2、the valve is easy to operate: resilient sealed gate valve using elastic sealing material as the sealing vice, with less friction resistance, less operating force, can easily switch.

    3、Not easy to rust: the use of powder epoxy resin coating the valve body of the flexible sealing gate valve can make the valve body effective antioxidant, not easy to rust, but also can prevent the valve body from suffering corrosion. resilient sealed gate valve will be often used in the sewage treatment system.

     4、Not easy to erode: resilient sealed gate valve’s body internal use of non-toxic epoxy resin coating, the gate is completely wrapped by the rubber, can effectively avoid the valve body internal erosion by the medium in the pipeline.

      5、Light weight: resilient sealed gate valve using ductile iron as the valve body material, the overall weight of the valve is 20% -30% lighter than the traditional gate valve, lighter weight so that the soft sealing gate valve is more convenient to install and repair.

     6、Easy maintenance: resilient sealed gate valve has a simple structure and is easy to maintain. When the sealing material is worn or aged, the sealing vice can be easily replaced, and the maintenance cost is low.

      二、Disadvantages of resilient sealed gate valve

    1、 short life: resilient sealed gate valve life is relatively short, because the sealing vice is often in the deformation of the state of force, so generally in the use of a period of time after the need to replace the seals.

     2、The opening and closing time is long, because the gate valve opening and closing time must be fully open or fully closed, the gate stroke is large, open with a longer period of time.

     3、Resilient sealed gate valve can only be used in medium, low pressure, ordinary temperature of non-corrosive, non-particulate, non-abrasive conditions and media.

                                                                                  

    In conclusion, as a new type of valve, resilient sealed gate valve has many advantages and disadvantages. In the application of different fields, it is necessary to choose the right type of valve according to the actual situation in order to achieve the best use. In the future, with the continuous progress of technology and application needs continue to improve, resilient sealed gate valve will be more widely used and developed!
