    Instructions for installation and maintenance of axial check valve

    The axial check valve produced by JALYSO PRECISION MACHINERY CO., LTD is suitable for use in clean natural gas, water, steam and other medium pipelines at temperatures between -29 and 100 °C. It has the advantages of small flow resistance, good flow regime and long service life. An ideal device to prevent backflow of media.

  • How to design the valve flap structure of the axial check valve?

    The axial check valve is widely used in oil and gas collection because of its smooth operation, small flow resistance, small water hammer pressure, good flow state, fast response to medium pressure changes, small size, low noise and good sealing. Pump outlets such as pump networks, fire-fighting and petrochemical pipelines are used as check-off devices.

    Precautions for installation and use of axial check valve

    Axial check valve is an important classification of check valves. A check valve is a valve in which the opening and closing member is a circular flap and acts on its own weight and medium pressure to block the flow of the medium. Check valves are often used as bottom valves for pumping devices to prevent backflow of water. The combination of the stop valve and the shut-off valve provides a safe isolation.

  • Working principle and performance characteristics of axial check valve

    The axial check valve is a type of check valve. The check valve is an automatic valve. Its main function is to prevent the medium from flowing backward, to prevent the pump and drive motor from reversing, and to vent the container medium. Check valves are also known as check valves, counterflow valves, check valves, and back pressure valves.

    How to choose the right size and type of center line butterfly valve

    How to choose the right size and type of center line butterfly valve?Generally, in the throttling, regulating control and mud medium, the structure length is short, the opening and closing speed is fast (1/4 turn). Low pressure cut-off (small pressure difference), it is recommended to choose butterfly valve.

    Structure and working principle of lift type check valve

    Lift type check valve is a kind of valve to prevent the reverse flow of pipeline media, mainly composed of valve body, valve seat, disc, cover and other related parts. The lift-type check valve has a spring to ensure that the disc is always in a state of dynamic balance under the action of the spring and that the valve can maintain a balanced operation regardless of the medium pressure at the inlet end of the valve.

    What is the difference between an axial flow type check valve and a general check valve?

    Axial flow check valve is also called through check valve.The working principle of the check valve is to open and close the valve disc automatically depending on the flow of the medium itself to prevent the reverse flow of the medium.

    Notes for the installation of life type check valve

    When installing the check valve, pay special attention to the flow direction of the medium, the normal flow direction of the medium should be consistent with the direction of the arrow indicated on the valve body, otherwise it will cut off the normal flow of the medium.
