    Cryogenic Safety Valve Notes


    1 . It should ensure that the pipe is blown clean before installation.


    2 . When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.


    3 . This valve has been degreased. Store and keep clean when installing.


    4 . After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.

    Common Sense Of Cryogenic Fall Lift Safety Valve

    1. Pass the low temperature performance test to ensure the low temperature performance of the material and the comprehensive mechanical performance, strength and rigidity of the workpiece;

    2. The valve stem adopts a lengthened structure, and the design includes a self-adjusting lengthening system to reset the wear, tightening and expansion caused by thermal energy changes;

    3. It has a structure to prevent abnormal pressure rise, and a pressure relief hole is provided to release the overpressure caused by the heat of the liquid medium trapped in the valve cavity;

    4. When operating at high temperature under low temperature conditions, there is no jamming or scratching of internal materials.
