Embodiment 1

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

[0040] The new electromagnet also includes armature 2 and push rod 3. The armature 2 is installed in the housing 01 through a DU bearing (ie a polytetrafluoroethylene composite bearing) 014 , and can move up and down relative to the housing 01 . The DU bearing (ie PTFE composite bearing) 014 can avoid the direct contact between the armature 2 and the housing 01, and prevent the housing 01 from being worn. DU bearing 014 can work under non-lubricated conditions, with low frictional resistance, wear resistance, and long service life, which minimizes the wear of the armatur...

Embodiment 2

[0055] The difference from Embodiment 1 is that the driving device for the fire extinguishing system in this embodiment does not include the blocking iron 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 drive device for a fire extinguishing system. Background technique [0002] Fire is one of the most frequent and common major disasters that 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 fire extinguishing agent such as clean gas is ejected to extinguish the fire. Manual drive response is slow and time-consuming, and it is very likely that the fire will spread due to missing the best time to extinguish the fire, resulting in loss of personnel or property. SUMMARY 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 object, the p...
