Regus Regus import stop valve
The shut-off valve, also known as the gate valve, is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. When the medium enters the valve from under the valve flap, the resistance to be overcome by the operating force is the friction between the stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the valve stem The dia
meter of the stem should be large, otherwise the valve stem can be bent. There are three types according to the connection method: flange connection, thread connection, and welding connection. After the self-sealing valve appears, the medium flow direction of the shut-off valve is changed into the valve cavity from above the valve flap. At this time, under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, and the dia
meter of the valve stem can be correspondingly Reduced. At the same time, this type of valve is also tight under the action of the medium.
The opening and closing member of the stop valve (Globe Valve) is a plug-shaped valve flap having a flat surface or a sea cone surface, and the valve flap moves linearly along the center line of the valve seat. The movement of the valve stem, (common name: dark rod), and the lifting rotary rod type 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 globe valve is well suited for shut-off or regulation and throttling. Due to the relatively short opening or closing stroke of the valve stem of this type of valve, and the very reliable cutting function, and because the change of the valve seat opening is proportional to the stroke of the valve flap, it is very suitable for the adjustment of the flow rate.

Regus Regus import cut-off valve definition:
The shut-off valve, also called the cut-off valve, is one of the most widely used types of valves. It is popular because it has a small friction between the sealing surfaces during opening and closing, is relatively durable, and has a small opening height and is easy to manufacture. Easy to maintain, not only for medium and low pressure, but also for high pressure. The closing principle of the shut-off valve is that, relying on the pressure of the valve bar, the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the medium from flowing.
