Working principle and advantages of high pressure and high temperature gate valve
The high-pressure and high-temperature gate valve is a common cut-off valve. Such a valve can directly cut off the medium in the pipeline, but it cannot be used for flow adjustment. This kind of valve has strong adaptability and can be used in various pressure and temperature environments. So what are the working principles and advantages of this type of valve?
working principle
The high pressure and high temperature gate valve of the upper pot valve adopts a compact structure. The pressure self-tightening structure can ensure a good application effect, and there are elastic splints inside, and the branch pipes on both sides can be directly used as welding connections, so that subsequent installations More convenient. The cobalt-based cemented carbide is used for spray welding on the valve seat sealing surface, so it can ensure good wear resistance and also ensure the sealing effect.
In addition, the surface of the valve stem is also treated with corrosion resistance, so even the valve can be used for a long time to ensure good durability, and only simple cleaning is required daily. The opening and closing of the high-pressure and high-temperature gate valve are directly controlled by electric devices. The design of electric devices is reasonable and compact, which is conducive to on-site operation and control. At the same time, it can be controlled manually and remotely controlled remotely, which also improves The utility of the valve.
Valve advantages
Wide range of applications. Because the middle cavity of the valve adopts a self-tightening sealing structure, as the pressure in the inner cavity increases, the sealing performance will also improve. Moreover, the welding points on both sides are more obvious, which can meet different installation requirements. The welding is convenient, and the scope of application is also improved. Moreover, the valve can be remotely controlled, so it is very convenient to operate, and a variety of control modes are available.
Strong corrosion resistance
The corrosion resistance of the high pressure and high temperature gate valve is still very good. From the welding surface to the overall material of the valve, it has very good corrosion resistance, which further improves the overall performance of the valve. The valve can guarantee good wear resistance, and high temperature resistance is also guaranteed. Such a valve can also guarantee a longer service life.
