Safety overflow valve | Safety reflux valve

The safety overflow reflux valve refers to two types of safety valves that have similar functions but lead to different results. The working principle of a safety relief valve is based on its internal structure. Typical structural forms of safety relief valves include piston type safety valves, with a flat valve core. When the pressure of the air source acts on the piston and exceeds the safe value determined by the spring force, the piston is pushed open, and a part of the compressed air is discharged into the atmosphere from the valve port; When the pressure of the gas source is lower than the safe value, the spring drives the piston to move downwards, closing the valve port. The valve overflow port is open and can be directly discharged into the atmosphere. The main feature of the safety reflux valve produced by Shanghai Meiyan Yi Pump Valve is that the inlet and outlet are generally on the same horizontal line, which is different from the inlet and outlet of other safety valves with angular designs. A safety reflux valve is a valve used to protect a system from damage caused by excessive pressure. When the pressure of the medium in the system pipeline or device exceeds the set value, the valve automatically opens and releases some of the medium, achieving the function of pressure reduction and stabilization. When the inlet pressure drops to the normal range set value, the valve automatically closes and locks the gas source to prevent waste caused by abnormal start-up. The safety reflux valve produced by Shanghai Meiyan Yi Pump Valve is widely used in various systems that require pressure control, especially in industrial pipeline systems. It can automatically open and quickly close to prevent backflow and protect the safe operation of pipeline systems. In addition, the safety reflux valve is also suitable for liquid phase outlet pipes of liquefied petroleum gas and other media, and can automatically reflux into the tank when the pressure difference reaches a certain value, ensuring the safety of the system.
