What is a full -enabled safety valve
Full -opening safety valve refers to a safety valve that enables the diameter of 1/4 of the 1/4 flow channel.The movement characteristics of this safety valve belong to the two -stage functional valve.The main parameters of the safety valve are displacement. This displacement determines the height of the caliber of the valve seat and the opening height of the valve petals. The height is different from the opening height, and it is divided into two types: micro -opening and full -opening.Micro -opening refers to 1/40 ～ L/20 of the valve lobes opening height.Full -opening refers to the opening height of the valve petals to 1/4 of the valves throat diameter.Full -opening safety valve: The application in the steam medium is generally a sudden full -operated action. The pressure during this upward movement is the setting pressure (sudden jump pressure);The proportion increases, and then suddenly starts, called the second -stage opening; it is generally not available for liquid media.Micro -enabled safety valve: First increase the proportion of the increase in the height of the import pressure, and when the pressure decreases, it also decreases with the decrease in import pressure. It is generally used for liquid medium (or for compressed gas when protecting the pipeline).
