The present gas valve performs the basic sealing and flow control functions through the control of the ball valve segment 19, a conventional ball valve when the locking function is not in use. When the locking function is used, the function of the electromagnetic valve section 4 can be started by controlling the locking component 6, so that the gas valve is locked.

The control rod 34 is sleeved with a secondary tension spring 35, the lock cylinder 30 is sleeved with a torsion spring 29, and two ends of the torsion spring 29 are fixedly connected with the lock body 5 and the lock cylinder 30 respectively; the two ends of the secondary tension spring 35 are fixedly connected with the upper wall of the locking component 6 and the control block 32 respectively; the control block 32 is inclined to engage the triangular latch 36.

After the key is pulled out, the torsion spring 29 tensioned when the lock cylinder 30 rotates automatically rebounds, and the limit clamping block 31 is reset.

When the electric signal of the pressure sensor 37 disappears, the electromagnetic coil 24 is powered off, the electromagnet 23 loses magnetism, the pressure spring 25 in a compressed state is flushed and released because the permanent magnet plate 28 moves, the permanent magnet plate 28 is pushed back to the top end of the electromagnetic valve cover 27, at the moment, the interception stem pulls the valve plate 22 back into the through groove 21, and the electromagnetic valve section 4 is communicated, so that unlocking is completed.

The working principle of the invention is as follows:

the fuel gas is provided with the electromagnetic valve section 4 and the ball valve section 19, and the ball valve section 19 is in a sealed or communicated state through the sealing ball 10 and the control knob 13 under the condition of no locking and can be adjusted through manual control. When the device needs a locking function, the control rod 34 is pressed down through the use of the locking assembly 6 to drive the triangular clamping block 36 to move towards the lock cylinder 30 and clamped on the limiting clamping block 31, so that the pressure sensor 37 is separated from a pressure state to send out a signal, the permanent magnet is adsorbed by the electromagnet, and the valve plate 22 is driven to be inserted into a communicating pipeline to realize the complete sealing of the gas valve; when the device needs to be unlocked, the lock cylinder 30 is rotated by using a key, the lock of the lock cylinder 30 and the triangular clamping block 36 is released, the pressure plate 39 applies pressure to the pressure sensor 37, an electric signal disappears, the electromagnet loses magnetism, the side valve plate 22 returns to the through groove 21, and the gas valve is communicated.
