Manual Emergency Switch Battery Valve

Characteristic
Manual switch in the case of power failure,can be emergency switch hedging,make up for the ordinary solenoid valve in the case of no power,can not be closed shortcoming.


Industrial Automation Systems: In the automated production lines of industrial fields such as chemistry, petroleum, metallurgy, and electricity, it is often used for the emergency cut-off or conduction of fluids (such as liquids and gases) in pipeline systems to ensure the safety of production equipment and personnel. For example, when an abnormal situation occurs in the chemical production process, the manual emergency switch solenoid valve can be used to quickly cut off the supply of raw materials and prevent the accident from expanding.
Fire Protection Systems: In the fire protection water system, the manual emergency switch solenoid valve can be used to control the flow direction and on-off of the fire protection water. When a fire breaks out, the staff can manually operate the solenoid valve to ensure that the fire protection water can be accurately supplied to the areas where fire extinguishing is required, such as the automatic sprinkler system and the water curtain system.
HVAC Systems: In heating, ventilation and air conditioning (HVAC) systems, it is used to control the flow of media such as chilled water, hot water or steam. When the system malfunctions or requires emergency adjustment, the manual emergency switch solenoid valve can be used to quickly change the fluid path or stop the fluid supply to protect the equipment and maintain the basic operation of the system.
Water Supply and Drainage Systems: In urban water supply and drainage systems as well as the water supply and drainage systems inside buildings, the manual emergency switch solenoid valve can be used to control the flow of water to deal with emergency situations such as pipeline bursts and equipment failures, avoiding the waste of water resources and water disasters.


Normal Working State: Under normal circumstances, the solenoid valve generates a magnetic field when the electromagnetic coil is energized, attracting the valve core and making the valve core move upward against the spring force, thus opening the valve and allowing the fluid to pass through. At this time, the manual operating mechanism is in a non-operating state and does not affect the normal electromagnetic control of the solenoid valve.
Emergency State: When manual operation is required in an emergency, the valve core is directly acted on through the manual operating mechanism, such as rotating the handle or pressing the button. The external force provided by the manual operating mechanism overcomes the spring force and the fluid pressure, causing the valve core to move, achieving the opening or closing of the valve without being controlled by the electromagnetic coil. In this way, even in the case of electromagnetic coil failure, power interruption or other problems in the electrical system, the control of the solenoid valve can still be ensured to meet the requirements of emergency treatment.
