Embodiment 1

[0039] Such as Figure 1-5 As shown, the electromagnetic drive device for the fire extinguishing system includes a new type of electromagnet. The new electromagnet includes housing 01. The housing 01 includes a barrel 011 and an end cap 012 . The barrel 011 is provided with a cavity 013 . The end cap 012 covers the cavity 013 from the upper end of the barrel 011 and is riveted together with the barrel 011 .

[0040] The novel electromagnet also includes an armature 2 and a push rod 3. The armature 2 is installed in the housing 01 through a DU bearing (ie polytetrafluoroethylene composite bearing) 014, and can move up and down relative to the housing 01. The DU bearing (that is, the polytetrafluoroethylene composite bearing) 014 can avoid the direct contact between the armature 2 and the shell 01, and prevent the shell 01 from wearing and tearing. DU bearing 014 can work under no-lubrication conditions, with small frictional resistance, wear resistance and long service lif...

Embodiment 2

[0055] Different from Embodiment 1, the driving device for the fire extinguishing system in this embodiment does not include the stopper 5, and the armature 2 is a permanent magnet. The coil 4 is energized, and by controlling the current flow in the coil 4 , the coil 4 generates a magnetic field opposite to the magnetic pole of the armature 2 . The armature 2 pushes the push rod 3 to move downward under the action of the magnetic field.

Abstract

The invention provides a novel electromagnet. The novel electromagnet is characterized by comprising a shell and a coil, wherein the coil is arranged in the shell. The novel electromagnet further comprises an armature, wherein the coil surrounds the armature; and the armature can be driven to move by electrifying the coil. The novel electromagnet further comprises a push rod, wherein the push rod and the armature are connected in the shell; and the armature pushes the push rod to move during moving. According to the novel electromagnet and an electromagnet drive device for a fire extinguishing system provided by the invention, by electrifying the coil, the coil instantly generates a magnetic field to drive the armature to move. The armature moves to push the push rod to extend out of the shell. The push rod extending out of the shell can drive a control valve of the fire extinguishing system to be opened, so that fire extinguishing agents such as clean gas can be sprayed out for fire extinguishing. The consumed time for electrifying the coil and pushing the push rod to extend out of the shell is far shorter than the consumed time for manually driving the control valve to be opened, so that the possibility of extinguishing combustion sources in first time and preventing fire from spreading is increased.

Description

technical field [0001] The invention relates to a novel electromagnet and an electromagnetic driving device for a fire extinguishing system. Background technique [0002] Fire is one of the major disasters that most frequently and universally threaten public safety and social development. Nowadays, many factories or houses are equipped with fire extinguishing systems. When a fire occurs, the control valve of the fire extinguishing system is manually driven to open, so that the clean gas and other extinguishing agents are sprayed out to extinguish the fire. Manual driving is slow in response and takes a long time. It is very likely that the fire will spread due to missing the best fire extinguishing time, resulting in loss of personnel or property. Contents of the invention [0003] The purpose of the present invention is to provide a novel electromagnet equipped with a movable push rod in order to overcome the deficiencies in the prior art. [0004] To achieve the above ...
