The importance of fire protection for regulating valves
The control valve is the final control element that changes the process parameters such as medium flow, pressure, temperature, liquid level by means of power operation by accepting the control signal output by the adjustment control unit, also known as the control valve.
In chemical, petroleum and other automation systems, once a fire occurs, if some equipment in the system can cut off the flammable fluid leading to the fire environment in time, the fire can be prevented from spreading directly from the fire area to all parts of the plant. huge loss.
The regulating valve is an important part of the automation system. It is installed in the field to control the flow path. Therefore, it is the main equipment to cut off the flow path and prevent the flammable fluid from leading to the fire when the gunpowder smells. In the event of a fire, it is critical whether it opens or closes. Since the regulating valve is automatically controlled by the regulator in the control room and is not manually operated, the main characteristics of the fire valve should be: it can withstand temperature regulation and work for a short period of time, or when it is closed with hard work, the leakage should be small. The fire resistance of the valve should be considered as a very required performance, hoping to attract the attention of the relevant personnel.
The above is the importance of fire prevention of the regulating valve shared with you today. We must pay attention to the fire resistance to avoid subsequent safety problems.
