What are the similarities and differences between regulating valve and safety valve？

During use, if the system pressure is too large, the safety valve will jump. The pressure regulating valve can set the pressure value. When the pressure is higher than this value, the valve opens, and when the pressure is lower than this value, the valve closes. If we look at it this way, the regulating valve can be used as a safety valve. What is the difference in performance?

Safety valves are used to protect pipelines or equipment. The pressure is very high and the pressure is released. The pressure regulating valve is to keep the downstream pressure stable, mainly to ensure the stability of the downstream flow. In short, the safety valve is to keep the front pressure of the valve stable, and the regulating valve is used to maintain the valve after the pressure is stable. Of course, the two cannot be interchanged!

The safety valve can be automatically opened and closed according to the system working pressure. Generally, equipment or piping installed in a closed system protects the safety of the system. When the pressure in the equipment or pipeline exceeds the pressure set by the safety valve, the pressure is automatically opened to ensure that the pressure of the medium in the equipment and pipeline is below the set pressure, so as to protect the equipment and pipeline and prevent accidents. The regulating valve is used to regulate the flow, pressure and liquid level of the medium. According to the signal of the regulating part, the valve opening is automatically controlled to realize the adjustment of medium flow, pressure and liquid level. Under normal circumstances, the safety valve is opened in the event of an accident. After opening, physiological verification is theoretically required, and the regulator is open to regulate flow or pressure under normal conditions.Safety Valve - Set a pressure point, a high pressure, and jump immediately.Pressure Regulating Valve - Sets a pressure point where the upstream pressure is one higher than this, it keeps the downstream pressure problem normally open!

A safety valve is a safety design for a single piece of equipment or pipeline. When the pressure is too high, it will automatically jump off to restore the pressure to its normal working value. At the same time, it plays a protective role to prevent equipment damage or accidents due to excessive pressure. As the name suggests, regulators play the role of regulators. It acts as a regulator to control process parameters. Its purpose is to stabilize or regulate control of some or some temperature, pressure, flow or liquid level points upstream or downstream!Safety valves are generally used on pressure vessels and are safety accessories. They must be strictly checked. If the safety valve cannot be adjusted by itself, it must be checked after adjustment.
