Problems solved by technology

[0002] In the application of fire-fighting equipment in the lithium battery production line, the solenoid valve is an important component to control the fire-extinguishing system for partition selection. In the existing market, the open-close feedback signal of the solenoid valve is generally detected by detecting the power supply of the solenoid valve and using an electromagnetic induction switch. There are two ways to detect the opening of the spool, but these two methods find that if the solenoid valve fails in practical applications, such as solenoid valve coil failure, spool stuck fault, as long as the power supply energizes the solenoid valve coil, or the electromagnetic induction switch Affected by the magnetic field of the solenoid valve coil, the opening and closing feedback signal will still have feedback, and the feedback signal will be returned to the host. The host thinks that the solenoid valve has opened and closed, and proceeds to the next step, but the actual solenoid valve itself is not open. , when the lithium battery storage location catches fire, the fire extinguishing agent cannot be transported from the solenoid valve to the storage location for fire extinguishing. If the fire extinguishing is not timely, it may easily cause safety accidents. Afterwards, multiple investigations are required to determine the cause of the faulty solenoid valve. Will cause a lot of cost loss, therefore, there is room for improvement

Embodiment 1

[0022] to combine figure 1 and figure 2 , a fire solenoid valve that can detect the opening and closing state. The solenoid valve includes a valve body 1 and an electromagnetic static iron core 2. Both the valve body 1 and the electromagnetic static iron core 2 are existing technologies and will not be described again. Body, electromagnetic dynamic iron core 4 and valve core 3 in the housing. The electromagnetic dynamic iron core 4 is an integrated structure connected by a connecting piece in the middle, and can move along the axial direction of the electromagnetic static iron core 2. When the electromagnetic valve is energized , the electromagnetic static iron core 2 generates magnetic force, and because the electromagnetic dynamic iron core 4 is set in conjunction with the valve core 3, the valve core 3 will also move up, thereby opening the electromagnetic valve.

[0023] This kind of solenoid valve is used in the fire fighting system. The fire fighting system includes th...

Embodiment 2

[0030] to combine image 3 and Figure 4 , except for the specific structure of the spool movement detection mechanism, other contents of this embodiment are consistent with those of Embodiment 1.

[0031] Specifically, the spool motion detection mechanism includes a second linkage rod 12 and a second micro switch 13, the second micro switch 13 is threadedly mounted on the side wall of the valve body 1, and the triggering principle of the second micro switch 13 is the same as that of the first micro switch 13. The trigger principle of a micro switch 6 is basically the same. The second linkage rod 12 is horizontally installed in the valve body 1, one end of the second linkage rod 12 is connected to the valve core 3 in transmission, and the other end of the second linkage rod 12 is spaced from the micro switch. When the electromagnetic static iron core 2 is energized , the electromagnetic dynamic iron core 4 drives the second linkage rod 12 to move upward, and the second linka...

Abstract

The invention provides a fire-fighting electromagnetic valve capable of detecting opening state and closing state, and relates to the technical field of fire-fighting protection accessories. The fire-fighting electromagnetic valve is used in a fire-fighting system. The fire-fighting electromagnetic valve comprises a control main machine, the electromagnetic valve comprises a valve body and an electromagnetic static iron core, the valve body comprises a shell, a valve core and an electromagnetic dynamic iron core, and the valve core and the electromagnetic dynamic iron core are located in the shell; and the electromagnetic dynamic iron core and the valve core are arranged in a linkage manner, a valve core motion detection mechanism is arranged in the electromagnetic valve, the valve core motion detection mechanism monitors the motion of the valve core in real time, and the valve core motion detection mechanism is electrically connected with the control main machine. According to the fire-fighting electromagnetic valve, by detecting the starting and closing of the valve, faults of the electromagnetic valve can be rapidly tracked, the opening reliability of the electromagnetic valve in the fire fighting process is improved, the situation that because the main machine considers that the electromagnetic valve is opened and next-step work is performed, a fire extinguishing agent cannot be conveyed to a battery protection area through the electromagnetic valve to extinguish fire is avoided, and the valve has a manual opening-closing function.
