Production of high-pressure stainless steel globe valve

High pressure stainless steel globe valveSteam 64KG cut-off valve

Steam pressure refers to the gauge pressure of steam, and the absolute pressure of steam refers to the gauge pressure plus atmospheric pressure. For saturated steam, steam pressure refers to the saturation pressure at the corresponding temperature, which is determined by the fundamental properties of water.

The valve body structure design of the globe valve is quite tortuous, resulting in high flow resistance and energy consumption; Suitable for media such as steam and oil, not suitable for media with high viscosity, particles, easy coking, and easy precipitation.

Manual stainless steel globe valveworking principle

Globe valve is a widely used type of valve, and its popularity is due to the low friction between the sealing surfaces during the opening and closing process, which is relatively durable, has a small opening height, is easy to manufacture, and is easy to maintain. It is not only suitable for medium and low pressure, but also for high pressure.

The closing principle of a globe valve is to rely on the pressure of the valve stem to tightly adhere the sealing surface of the valve disc to the sealing surface of the valve seat, preventing the flow of the medium.

The shut-off valve only allows one-way flow of the medium and has directionality during installation. The structural length of the globe valve is greater than that of the gate valve, and the fluid resistance is high. During long-term operation, the sealing reliability is not strong.

Globe valves, gate valves, butterfly valves, check valves, ball valves, and so on are all control components in various pipeline systems today. Each type of valve has differences in appearance, structure, and even functional use. But globe valves and gate valves have some similarities in appearance, and both have the function of cutting off in pipelines, so many friends who have little contact with valves may confuse the two. Actually, if you observe carefully, the difference between globe valves and gate valves is quite significant.

The broad understanding of a reaction kettle is a stainless steel container with physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance need to be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. Pressure vessels must comply with the GB150 {Steel Pressure Vessels} standard, and atmospheric pressure vessels must comply with the NB/T47003.1-2009 {Steel Welded Atmospheric Pressure Vessels} standard. The pressure requirements during the reaction process also vary in terms of the design requirements for the container. Production must strictly follow the corresponding standards for processing, testing, and trial operation. Stainless steel reaction vessels vary according to different production processes, operating conditions, etc. The design structure and parameters of reaction vessels are different, that is, the structural style of reaction vessels is different, and they belong to non-standard container equipment.

The vapor pressure changes with temperature, and the higher the temperature, the greater the vapor pressure, which is also related to the type of liquid. The pressure generated by vapor in equilibrium with a liquid (or solid) state of the same substance at a certain temperature is called saturated vapor pressure, which increases with temperature. For example, the water placed in a cup will become less and less due to continuous evaporation. If pure water is placed in a sealed container and the air above is removed. When water continuously evaporates, the pressure of the vapor phase above the water surface, that is, the pressure of the water vapor, increases continuously. However, when the temperature is constant, the vapor phase pressure will eventually stabilize at a fixed value, and this vapor phase pressure is called the saturated vapor pressure of water at that temperature. When the vapor pressure reaches the saturation vapor pressure, the water molecules in the liquid phase continue to vaporize, and the water molecules in the vapor phase also continuously condense into liquid. It is only because the vaporization rate of water is equal to the condensation rate of water vapor that the amount of liquid does not decrease and the amount of gas does not increase, and the liquid and gas reach an equilibrium state. So, when the pressure of liquid pure substance vapor is its saturated vapor pressure, the gas-liquid phase reaches phase equilibrium. Saturated vapor pressure is an important property of matter, and its magnitude depends on the nature and temperature of the substance. The higher the saturated vapor pressure, the easier it is for the substance to evaporate.
