    Two ball valve installation

    Ball

    (1) the need to speak with the installation wrench tool manually, can be placed in any of the lines or equipment, but also left a wrench to rotate the position.

    (2) Installation ball with transmission components (such as electric, pneumatic or hydraulic, etc.), the need for upright installation, adjustment shall rule the operating instructions to install the product.

    Two ball valve works

    Two-piece ball valve is mainly used as a circular through holes open or close the valve, the sphere rotates slowly followed by the stem, to achieve rapid opening and closing action of the valve. Seal valve structure principle, ball floating ball valve and fixed ball two balls. Floating ball sphere rely on media pressure on the outlet end of the seat pressed, so the work pressure and path will be pressure limits. The ball valve is fixed to the upper and lower bearing support mounted on the valve body, the position of the ball in a fixed form, the seal of the implementation is to rely on the use of force of the spring and the media to pressure the seat to the ball, because some valve opening and closing torque, and suitable for installation in environments with high pressure and large diameter.

    The main standard two-piece ball valve

    GB 12237-89 "Universal valve flange and welded steel ball valves"

    GB 8465.3-87 "thread connecting valve, globe valve, ball valve, check valve basic size iron"

    GB / T 15185-94 "iron and bronze ball valves"

    GB 8464-87 "thread connecting valve, closing valves, ball valves, check valves General technical conditions"

    JB / T 53167-94 "ball valve product quality grading"

    JB / Z 246-85 "hydrostatic valve life test procedures"

    Two ball valve features

    (1) fluid resistance. Full sphere passage sectional area of the valve channel and connecting pipes flat, but a straight line communication mode, the media will go through ball, but there are various types of valves in valve fluid resistance is minimal.

    (2) is preferably sealed. Ball elastic soft seal.

    (3) The structure is relatively simple, small size, light, and light weight. And the height is less than gate and globe valves.

    (4) open and close quickly. Simply open and close when the ball is rotated 90 degrees, easily and quickly. The disadvantage of the two-piece ball valve two-piece ball valve can not high temperature, the use of soft-seal valve, the temperature will be limited gasket material, seals and application of metal seal material may expand valve temperature range.
