Safety valve and control valve in use the difference

March 08, 2022

When the pressure is too high, the safety valve to take off; Pressure Control Valve can set a pressure above which the valve opens below which the valve closes. In this case, the valve is not equivalent to a safety valve? Performance is a big difference? Safety valve is to protect the pipeline or equipment, the pressure is high, the Pressure Relief Valve with pressure relief valve is to let the downstream maintain a steady pressure, mainly to ensure the stability of the downstream flow In a word, the safety valve is to maintain the valve pressure is stable Regulating valve is Maintain the valve pressure stability, the two of course not interchangeable! Safety valve according to the system's work pressure can automatically open and close, generally installed in the closed system of equipment or pipelines to protect the system security. When the pressure in the equipment or pipeline exceeds the set pressure of the safety valve, the relief pressure will be automatically turned on to ensure that the pressure of the medium in the equipment and pipeline is under the set pressure to protect the equipment and the pipeline and prevent accidents. Control valve is used to adjust the medium flow, pressure and level. According to adjust the position of the signal, the valve automatically control the opening, so as to achieve the media flow, pressure and liquid level adjustment. In general, the safety valve is open only after an accident, and the physiological check is theoretically required when the valve is opened. The control valve is normally open to regulate flow or pressure. Safety valve - Set a pressure point High pressure immediately jump immediately Mainly used in emergency situations is usually closed regulator - Set a pressure point upstream pressure is higher than this pressure it maintains the downstream pressure problem is usually open! Safety valve It is a safety design for a single piece of equipment or pipe that automatically opens when the pressure is high and returns the pressure to its normal operating value. At the same time it plays a protective role, to avoid the pressure is too high to make the equipment too high pressure to be destroyed or an accident. Regulating valve as the name implies adjustment, it plays a role in regulating the control process parameters, his purpose is to stabilize or regulate the control of upstream or downstream of one or several temperature or pressure or flow or liquid level and other parameters! Safety valve is generally Used in pressure vessels, are safety accessories, must be strong inspection. Safety valve can not adjust their own, after adjustment must be tested.
