      Forged steel high-pressure turbine ball valve Q347F

      Date:[2017-03-15]    hits: Forged steel high-pressure turbine ball valve Q347F

      Q347F forged steel ball valve products:

      Design features and implementation standards:

      1, design, manufacture according to API 6 D;

      2, the length of the structure by ANSI BI6.10;

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

      4, valve inspection and testing according to API STD.598;

      5, socket end with ASME B16.11;

      6, threaded end (NPT) with ANSI/ASME B1.20.1

      The main design features are: full size / shrinkage; 90 positioning and locking structure; the special form of "Y" head handle; fire and anti-static design, a pair of opposing butterfly spring; antiblowout stems; double sealing structure of valve stem thread middle; bolt, gasket seal valve cover

      Valve installation and other mechanical equipment installation, an installation posture, valve installation should be within the correct posture structure in line with the flow of media, the specific requirements of installation in accordance with the attitude of the valve structure type and operation requirements. In addition, the correct attitude contains neat, beautiful and generous sense, it is the modern art modeling, technical and artistic combination of both.

      Product structure and application of Q347F forged steel ball valve

      The three split connection forged steel ball valve, the valve seat in the two part series will be along the section and the valve axis perpendicular to the channel is divided into three parts, the whole valve stem along the central axis symmetrical, it is in the pipeline is mainly used for cutting, distribution and change the flow direction of medium. The sphere center position accurately under high pressure to ensure the pivot of its structure, ensure the valve performance good; standard seat with the spring structure, will push the ball seat, to ensure a good sealing performance of import and export; the use of built-in discharge valve, the valve in the cavity can be discharged; the pivot blowout proof structure to effectively prevent leakage; bearing, low friction coefficient, the torque is reduced to a minimum, so the valve opening and closing the valve rod and the valve body; effective contact, the anti electrostatic grounding device for superior performance. With excellent performance, high reliability, wide application, reasonable price and so on. Applicable to: chemical, petroleum, natural gas, metallurgy, and other industries and hydrogen sulfide containing media, impurities and corrosion of natural gas pipeline.
