STAINLESS STEEL GLOBE VALVE
The opening and closing part of the globe valve is a plug-shaped disc, the sealing surface is flat or sea-cone, and the disc moves linearly along the centerline of the valve seat. The movement form of the valve stem, (common name: non rising stem), also has a lifting and rotating stem type that can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. flow. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. Because the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat opening is proportional to the stroke of the valve disc, it is very suitable for flow adjustment.
WORKING PRINCIPLE
The working principle of the manual gobe valve is based on the movement of the valve disc on the valve seat. The valve disc moves linearly along the center line of the valve seat, and the cross-sectional area of the flow channel is adjusted by changing the distance between the valve disc and the valve seat, thereby achieving precise control and complete cutoff of the flow. During the closing process, the valve disc fits tightly against the valve seat under the pressure exerted by the valve stem, ensuring reliable closure of the sealing surface.
The main components of a manual globe valve include the valve body, valve bonnet, valve stem, valve disc, sealing surface, stuffing box and handwheel. The valve body is the main part of the globe valve, which is used to accommodate other components and connect to the pipeline system. The valve bonnet plays a role in sealing and protecting internal components. The valve stem connects the handwheel and the valve disc. By rotating the handwheel, the valve stem drives the valve disc to move up and down along the axis of the valve seat. The sealing surface is located on the valve seat and the valve disc to ensure the sealing performance of the valve in the closed state. The stuffing box is used to prevent leakage between the valve stem and the valve body.
