DETAILED DESCRIPTION

[0027] Referring to Figures 1-9 The technical scheme adopted in the embodiment is shown in the drawings. The technical scheme comprises a shell 1, a control box 2 arranged on the side of the shell 1, a valve column 3 arranged in the shell 1, a spring 4 arranged on the valve column 3, a stroke of the spring 4 being constrained by the shell 1, a switch cap 5 movably arranged on the top of the shell 1, a toggle switch 6 arranged on the bottom of the switch cap 5 and fixed on the top of the shell 1, a control mainboard 10 arranged in the control box 2, a strong magnetic induction module 12 arranged on the control mainboard 10 corresponding to the position of the switch cap 5, a communication module 13 further arranged on the control mainboard 10 and electrically connected with the strong magnetic induction module 12, a contact switch 8 arranged on the bottom of the shell 1 and electrically connected with the communication module 13, the contact switch 8 being a normally open switch, two of which are symmetrically arranged in the embodiment, a fixed top plate 7 arranged on the top of the spring 4, a trigger bottom plate 9 arranged on the bottom of the spring 4, the fixed top plate 7 being movably connected with the valve column 3 and constrained by the top of the shell 1, the trigger bottom plate 9 being fixed on the valve column 3, in the overall structure, one end of the spring is a movable end and the other end is a fixed end, in the closed state, the spring is in the stretched state, the top is constrained in a limiting sleeve on the top of the shell by the fixed top plate, the limiting sleeve is sleeved with an exposed section on the top of the valve column, the fixed top plate is movably connected with the limiting sleeve, so that the valve column can move up and down smoothly, and the fixed top plate is constrained by the shell, when the valve column is lifted to compress the spring, the top of the spring is in contact with the shell to provide a restoring force for the valve column in the opened state. In the prior art, the monitoring of the electromagnetic valve uses a sensor to monitor the position of the piston, but when other components such as switches and springs are abnormal, the monitoring cannot be performed, resulting in that the electromagnetic valve is in an abnormal state and cannot be found, affecting the safe use of the electromagnetic valve and causing safety hazards. Therefore, in the embodiment, three groups of monitoring positions are arranged, one of which is the induction monitoring of the strong magnetic induction module and the switch cap, the second is the trigger monitoring of the switch cap and the toggle switch, and the third is the trigger monitoring of the spring and the contact switch. The top of the switch cap 5 is provided with a strong magnet, the bottom of the toggle switch 6 is also provided with a strong magnet, and the inside of the strong magnetic induction module is provided with a sensing head. When the electromagnetic valve is in the energized state and the switch cap is in the top position, the distance between the strong magnet inside the switch cap and the strong magnet inside the toggle switch is far, the magnetic attraction is weak, the sensing head detects a weak magnetic signal and sends an energized state information. When the electromagnetic valve is to be closed, the switch cap goes down, the distance between the two strong magnets becomes short, the magnetic attraction increases, the sensing head detects the increase of the magnetic force, sends a closed state signal to the communication module, the communication module is also a control module, controls the on-off of the circuit, and the communication module sends the use state of the switch cap to the control center.

[0028] When the switch cap is pressed to compress the paddle switch, the paddle switch is powered on to send a power-off signal to the communication module, and the communication module sends the paddle switch power-off information to the control center;

[0029] When the paddle switch sends a power-off signal, the communication module controls the coil to power off and release the valve column to close the air hole. At this time, the spring pushes the trigger base plate to reset, so that the trigger base plate compresses the contact switch. Since the contact switch is a normally open switch, when it is in contact with the trigger base plate, the switch is opened and powered on, sending a power-off signal to the communication module. The communication module sends its power-off state information to the control center and simultaneously sends the equipment closed state information to the control center.

[0030] Similarly, when the electromagnetic valve needs to be opened, the switch cap is reset, and the strong magnetic induction module senses that the reset magnetic attraction force is weakened, sending a power-on signal to the communication module. The switch cap and the paddle switch are separated, the paddle switch sends a power-on signal to the communication module, the communication module sends a power-on command, the coil is powered on to attract the valve column, the spring is compressed by the trigger base plate, the bottom of the valve column 3 is provided with a sealing plug 3-1, the sealing plug leaves the air hole, and at the same time the trigger base plate leaves the contact switch, the contact switch resets and disconnects and sends a power-on signal to the communication module, and the communication module sends a state signal to the control center to display that the electromagnetic valve is in a power-on state. When using power-on, if one of the three monitoring positions is abnormal, such as the trigger base plate falling off and not separating from the contact switch, the contact switch is not disconnected, no power-on signal is sent to the communication module, and the communication module only sends a power-on signal to the control center. At this time, the communication module sends an abnormal signal to the control center, reminding the maintenance personnel to overhaul the electromagnetic valve, so as to ensure the normal use of the electromagnetic valve.

[0031] In addition, the control center is also provided with an alarm, and the pipeline is also provided with an alarm. When gas leakage occurs, the alarm sends an alarm signal to the control center, the control center can directly send a power-off closing signal to the communication module, the communication module sends a power-off command to directly power off the coil, the valve column retreats to close the air hole, and the pipeline is closed, so as to realize real-time monitoring and control of the valve remotely, and improve the use convenience and safety of the valve.

[0032] More specifically, the control box 2 is provided with a detachable battery 11, the battery 11 is electrically connected with the control mainboard 10, in the embodiment, the battery is detachable, and the battery can be taken out from the side cover of the control box for replacement; the control mainboard 10 is further provided with an electric quantity detection module 14, the electric quantity detection module 14 is electrically connected with the battery 11, and the electric quantity detection module is further electrically connected with the communication module; when the electric quantity is lower than 20%, the battery usage condition is fed back to the communication module, the communication module is fed back to the control center, the battery usage condition is reminded, when the electric quantity of the battery is lower than 10%, the communication module sends a power-off instruction to power off the electromagnetic valve, so that the electromagnetic valve cannot normally work due to low power and gas leakage is avoided, and the use safety is ensured.

[0033] More specifically, the communication module 13 is connected with the control center through an external gateway, the control center and the electromagnetic valve are provided with gateways, the communication module sends all monitoring signals to the gateway first and then sends the monitoring signals to the control center through the gateway, so that the signal is normally transmitted.

[0034] More specifically, the communication module 13 includes a wireless network module and a Bluetooth module, the signal transmission of the communication module is in two modes, one is to send signals through the connection of the wireless network module and the gateway, and the other is to send monitoring signals by establishing a connection with a nearby terminal device through the Bluetooth module; the terminal device can also be used as the control center to control the electromagnetic valve to be powered on and off, and various use modes ensure the normal control operation of the device.

[0035] The working principle of the present application: when the electromagnetic valve is to be closed, the outer cover on the switch cap 5 is opened, the switch cap 5 is pressed down, the toggle switch 6 is pressed down, the toggle switch 6 sends a power-off signal, the communication module sends a power-off instruction, the coil is powered off to release the valve column 3, the sealing plug 3-1 is in sealing connection with the bottom air hole of the shell 1, the pipeline is closed, at the same time, due to the downward pressing of the switch cap 5, the distance between the strong magnet in the switch cap 5 and the strong magnet in the toggle switch 6 changes, the strong magnetic induction module 12 senses that the suction force increases weakly, sends a closing state signal to the communication module 13, and when the valve column 3 goes down, the trigger bottom plate 9 at the bottom of the spring 4 presses the contact switch 8, the contact switch 8 sends a power-off signal to the communication module 13, the communication module 13 sends three power-off use state signals from the strong magnetic induction module 12, the contact switch 8 and the toggle switch 6 to the control center at the same time, so that the control center can clearly understand the use state of the electromagnetic valve, when the switch cap 5 is reset for use, the strong magnetic induction module 12 senses that the switch cap 5 is reset upward, the distance between the two strong magnets becomes far, the magnetic attraction force weakens, a reset power-on signal is sent to the communication module 13, the switch cap 5 leaves the toggle switch 6, the toggle switch 6 is reset, a power-on signal is sent to the communication module 13, at the same time, the communication module 13 sends a power-on instruction, the coil is powered on to attract the valve column 3, the spring 4 is compressed under the action of the trigger bottom plate 9, the valve column 3 goes up, at the same time, the trigger bottom plate 9 is separated from the contact switch 8, the contact switch 8 is reset and disconnected and sends a power-on signal to the communication module 13, the communication module 13 sends a state signal to the control center again to show that the electromagnetic valve is in a power-on state, only when the three sensing devices send signals at the same time, the communication module 13 sends a normal equipment use signal to the control center, otherwise, an abnormal equipment signal is sent, and the electromagnetic valve is directly closed.
