The self-sealing globe valve includes a valve body with a cavity integrally formed at the bottom end of the valve body. A sealing cap is detachably connected to the valve body. A sealing valve seat is provided in the valve body. A valve stem and a valve stem are inserted in the cavity of the valve body. One end is provided with a valve disc that cooperates with the sealed valve seat, and the other end of the valve stem is connected with a pressing component for controlling the opening or closing of the valve disc and the sealed valve seat. The two sides of the valve body are respectively provided with a medium inlet communicating with the cavity. And the media outlet, the position where the media inlet is connected to the cavity is lower than the position where the media outlet is connected to the cavity. The utility model provides a self-sealing cut-off valve. The valve rod seal movement direction is the same as the sealing medium flow and pressure direction, and the seal is stable and reliable. In addition, the valve body with a cavity is integrally formed, and the sealing cover is detachably connected to the valve body, which reduces assembly accuracy and improves maintenance efficiency.MORE
1. Performance of high-pressure casting globe valve: Because the change of valve seat channel of high-pressure casting globe valve is proportional to the valve stroke. The opening or closing stroke of the high-pressure cut-off valve is relatively short, and it has a very reliable shut-off function. Because the change of the valve seat passage is proportional to the stroke of the valve disc, it is very suitable for adjusting the flow. Therefore, this globe valve type is very suitable for shut-off or regulating and throttling. Because the cast valve has a small stroke between the opening and closing of the valve, and the sealing surface can withstand multiple openings and closings, the valve is very suitable for occasions that require frequent opening and closing, and can be used in most media flow systems. Globe valve is widely used in petrochemical, electric power, metallurgy, urban construction, chemical and other industries.MORE
Forged steel is simply used for forging. Forged steel refers to various forging materials and forgings produced by the forging method. The quality of forged steel parts is higher than that of cast steel parts, and it can withstand large impact forces. The plasticity, toughness and other mechanical properties are also higher than those of cast steel parts. Forged steel is generally used in high-pressure pipelines. It has the characteristics of fine organization and suitable for high pressure working conditions.MORE
