How to regulate the ventilation volume of the explosion proof vent plug - Wuxi Sinceriend New Material Technology Co., Ltd.

The ventilation volume regulation of the explosion proof vent plug is crucial, which is related to the safety of equipment operation and environmental stability. It can be achieved in the following ways.
1. Regulation from the design level
During the design and manufacturing stage of the explosion proof vent plug, the ventilation hole size and ventilation channel structure will be accurately planned according to the required ventilation volume of the equipment. A larger ventilation hole diameter and a smooth ventilation channel are conducive to increasing the ventilation volume, and vice versa. For example, large chemical storage tanks need to release a large amount of gas due to the violent reaction of internal substances. The matching explosion proof vent plug is designed with a large-diameter ventilation hole to meet the needs of instantaneous large-scale gas discharge.
2. Regulation based on pressure
The explosion proof vent plug has a specific opening pressure value. When the internal pressure of the equipment does not reach this value, the vent plug is in a closed or small opening state, and the ventilation volume is extremely small; once the internal pressure rises to the opening pressure, the vent plug quickly opens to an appropriate degree. The higher the pressure, the greater the opening degree, and the ventilation volume also increases accordingly. In this way, the ventilation volume can be flexibly adjusted according to the changes in the internal pressure of the equipment. During normal operation, the ventilation volume is maintained at a low level to ensure the airtightness of the equipment. When the abnormal pressure rise may cause danger, the ventilation volume is increased in time to relieve the pressure.
3. Control with auxiliary devices
Some explosion proof vent plugs are equipped with auxiliary equipment such as regulating valves and throttling devices. The regulating valve can manually or automatically adjust the flow area of the ventilation channel. The operator can accurately control the ventilation volume by adjusting the valve opening according to the actual working conditions. The throttling device indirectly adjusts the ventilation volume by changing the resistance of the airflow. For example, in some laboratory equipment with strict requirements on ventilation volume, the combination of regulating valves and throttling devices can accurately control the ventilation volume within the required range to ensure the safety and stability of the experimental environment.
