The linear Hall sensor has high precision and good linearity; the switch type Hall sensor has the advantages of no contact, no abrasion, clear output waveform, no shake, no rebound and high position repetition precision. Such as the SPH series hall sensor hall switch, believed.
As shown in fig. 9-12, at the same time, the controller 22 continues to send electric pulses to the ignition needle 24 on the side of the fire seed 30 of the burner 29 to perform electric pulse ignition, after the fire seed 30 is ignited, the flame burns the induction needle 25, a loop signal is generated and is transmitted back to the controller 22, and the controller 22 controls the valve core 2 to continuously suck, thereby completing the work of starting the fire seed.
As shown in fig. 13-16, when the main fire is needed, the rotating handle 19 rotates to a position of 180 degrees, at this time, the second cavity 5 is communicated with the third cavity 6, the third cavity 6 can be communicated with the main fire of the burner 29, meanwhile, the second cavity 5 is always communicated with the fourth cavity 7, the fire seed 30 is ventilated and burned for a long time, and the main fire power can be adjusted freely between the positions of 90 degrees to 180 degrees by the rotating handle 19.
When the main fire is not needed, the rotary handle 19 is rotated to a 90 position, as shown in fig. 9-12, to keep the ignition of the fire seed 30.
When the electromagnetic valve stops working, the rotary handle 19 rotates to a position of 0 degree, the strong magnet 20 of the square shaft 18 returns to a position capable of indirectly contacting the Hall switch 21, power supply is stopped at the moment, the fan 23 stops, the valve core 2 stops working and releases, the sealing rubber pad 3 presses the valve port of the electromagnetic valve body 1 under the action of the spring 31 to separate the first cavity 4 from the second cavity 5, the main gas circuit and the fire gas circuit are all closed, and the electromagnetic valve body 1 recovers a closed state as shown in figures 5-8, so that all work is completed.
When unexpected flameout midway occurs, the flame of the kindling 30 can not burn the induction needle 25, because the induction needle 25 and the controller 22 have no loop, the valve core 2 stops working and releases, the sealing rubber pad 3 presses the valve port of the solenoid valve body 1 under the action of the spring 31 to separate the first cavity 4 from the second cavity 5, and the main gas path and the kindling gas path are all closed, namely, in the closed state shown in fig. 17-20, thereby realizing the flameout protection function. At this time, the centralized control type gas safety valve can be restarted after the rotating handle 19 is rotated to the position of 0 degree.
When the air supply is the natural gas or the liquefied gas of different pressure, can adjust required main gas flow and the kindling flow through main gas restriction valve 10 and kindling restriction valve 8 in advance, so can be according to actual demand promptly, required flow is adjusted to better faster, structure setting through main gas restriction valve 10, can realize flow control between natural gas and the liquefied gas, realize shared regulation between the two, kindling 30 directly comes out from solenoid valve body 1, do not need additionally to increase the kindling switch again. And the mode is flexible and efficient, the gas safety valve and the related kitchen ware structure can be integrally simplified, and further the space and the installation cost are obviously saved.
The invention can replace the traditional electromagnetic valve, main gas switch, fire switch and other devices by installing the centralized control type gas safety valve, and compared with the prior art, the invention greatly simplifies the installation structure while ensuring the use safety, can realize the rapid production, rapid installation and rapid maintenance work in a modularized way, and is very convenient in operation.
