[0034] The control switch 31 is used to control the solenoid valve 32. The solenoid valve 32 can be a normally closed solenoid valve. When the power is off, the solenoid valve 32 remains closed. The controller can open or close the solenoid valve according to the signal of the control switch 31; but it is not limited to this. The control switch 31 can also be electrically connected to the solenoid valve 32.

[0036] Figure 6 A controllable switch 38 is also shown, the control end of the controllable switch 38 is connected to the controller 3, one end of the detection resistor R1 is connected to the detection line 45 through the controllable switch 38, and the detection line 45 is connected to the external connector. The controllable switch 38 is used to control the power supply of the detection line. In the first specific embodiment, the controllable switch 38 can be a relay, the two electrodes of the battery 39 are connected to the input end of the controllable switch 38, one output end of the controllable switch 38 is connected to one end of the detection resistor, and the other output end is connected to a detection line 45.

A connection groove 43 is provided between the first connector 21 and the external connector 4, and the connection groove 43 covers the detection line 45 through a lead seal layer or a glue seal layer.

[0041] More specifically, an insulating seat 41 is provided on the external connector 4, and at least one connector 42 is provided on the insulating seat 41. The connector 42 at a suitable position can be selected to install the detection line, and one end of the detection line 45 is installed on the connector 42; the connection strength between the detection line 45 and the connector 42 is less than the connection strength between the insulating seat 41 and the external connector 4, so as to avoid the insulation seat 41 and the external connector 4 from falling off, wherein the lead seal layer or the glue seal layer can cover the insulating seat.

[0048] Step 201: Determine whether the change in the detection signal of the detection circuit exceeds a preset threshold.

[0049] If yes, execute step 202: generate an alarm signal.

[0050] If not, execute step 203: continue to monitor the detection signal of the detection circuit.

[0051] In step 202, the following steps may also be used:

[0052] Step 221: Disconnect the power supply of the detection line through a controllable switch.

[0053] Step 222: Supply power to the detection line through the controllable switch at intervals to obtain a detection signal, for example, 3-10 seconds off and 1 second on.

[0054] Step 223: If the detection change exceeds the preset threshold for more than the second threshold, an alarm message is sent to the management personnel. For example, if the detection change exceeds the preset threshold for 3-7 consecutive times, the detection line can no longer be powered, that is, the controllable switch is turned off for a long time to stop powering the detection line.

[0055] The intelligent gas valve of the utility model can prevent the gas valve and its connected external joint from being illegally modified, and can detect gas leakage at the same time, so as to timely discover safety problems in gas use. When a safety problem occurs, on the one hand, the solenoid valve can be manually closed and the gas supply can be stopped through the control switch 31; on the other hand, the alarm information can be sent to the upper computer or server through the transmission module to notify the management personnel or users, which is conducive to timely solving the safety problem.
