Design Features:
The stem axis of the globe valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, which makes this valve very suitable for the cut-off or adjustment and throttling of the medium.
Once the valve disc of the shut-off valve is in the open condition, there is no longer contact between its valve seat and the sealing surface of the valve disc, and has a very reliable cut-off action. This kind of valve is very suitable for cutting or adjusting and reducing the medium. Stream usage. This type of valve should generally be installed horizontally in the pipeline.
Once the shut-off valve is in the open state, there is no contact between its seat and the sealing surface of the disc, so its sealing surface is less mechanically worn, because most of the valve seats and discs are easier to repair or replace It is not necessary to remove the entire valve from the pipeline when sealing the components, which is very suitable for the occasion where the valve and the pipeline are welded together. The flow direction of the medium through this type of valve has changed, so the flow resistance of the stop valve is higher than that of other valves.
1. The structure is simpler than the gate valve, and the manufacturing and maintenance are more convenient.
2. The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve clack and the valve body sealing surface when opening and closing, so the wear and scratches are not serious, the sealing performance is good, and the service life is long.
3. When opening and closing, the disc stroke is small, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
