    Stainless steel ball valve High - pressure turbine Q347F

    Date:[2016-10-20]    hits: Stainless steel ball valve High - pressure turbine Q347F

    Q347F forged steel ball valve Product Description:

    Design features and implementation of standards:

    1, the design, manufacture according to API 6 D;

    2, the length of the structure according to ANSI BI6.10;

    3, connection flange: ANSI BI6.5MSS-SP44;

    4, valve inspection and testing by API STD.598;

    5, sockets meet the ASME B16.11;

    6, threaded connector (NPT) in line with ANSI / ASME B1.20.1

    The main design features are: full diameter / reduced diameter; 90-degree positioning and locking structure; special form of "Y" head handle; fire and anti-static design, a pair of opposing butterfly springs; anti-blowout stem; Central double seal structure; bolts, threaded gasket seal valve cover

    Valve installation and other mechanical equipment installation, there is a problem of installation attitude, the correct attitude of the valve should be installed in line with the internal structure of the media flow, the attitude of the valve structure in line with the specific requirements and operational requirements. In addition, the correct posture contains a uniform, beautiful and generous feeling, it is the modern art form, the technical and artistic combination of the two organic.


    Q347F forged steel ball valve product structure and use

    Three-part connection forged steel ball valve, the valve seat in the two parts along the valve channel along the axis of the vertical section is divided into three parts, the whole valve along the stem axis symmetry, which is mainly used in the pipeline Cutting, distributing and changing the flow direction of the medium. Its large pivot structure ensures accurate ball center position under high pressure and ensures the good operation performance of the valve. The standard seat adopts spring structure to push the valve seat to the sphere, which ensures the good bidirectional sealing performance of import and export. Low friction coefficient of the bearings, making the torque reduced to a minimum, easy to open and close the valve; stem and the valve body is effective to prevent the leakage of the valve; Of the contact, so that anti-static grounding device superior performance. With excellent performance, high reliability, versatile, reasonable price and so on. Applicable to: chemical, oil, natural gas, metallurgy, and other industries and containing hydrogen sulfide media, impurities, corrosion of natural gas long-distance pipeline.
