    Standard for various types of globe valves
    SendTime:2017-01-05  Views:

    Valve opening and closing parts are plug shaped valve, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. The movement of the stem form, there are lifting rod (stem lift, hand wheel is not up and down), but also with the rotation of the rotary rod (hand wheel and stem together with the rotation of the nut in the valve body). Valve is only applicable to fully open and fully closed, does not allow for adjustment and throttle.

    The valve is a mandatory seal valve, so the valve is closed, the valve must be applied to force the sealing surface does not leak. When the medium into the valve six from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. In recent years, the emergence of self sealing valve, globe valve replaced by medium flow on the top of the valve into the valve chamber, then in the medium under pressure, the valve off a small force, and force open the valve, stem diameter can be reduced accordingly. At the same time, the role of the media, this form of valve is also more stringent. China's valve three to the provisions of the flow of the valve, will be top-down.

    When the valve is opened, the opening height of the disc, the nominal diameter of 25% ~ 30%, the flow has reached the maximum, indicating that the valve has reached the full open position. Therefore, the valve fully open position, the valve should be determined by the itinerary.
