Embodiment Construction
[0017] Attached below figure 1 with figure 2 The present invention is described further:
[0018] Such as figure 1 with figure 2 A kind of gas pipeline 3 safety leak-proof control method shown, its method is as follows:
[0019] (A), mandatory supply of gas flow for a predetermined time; before igniting the fire, the electromagnetic valve 2 must be forced to start with a control element (not shown in the figure) to generate an excitation action for a predetermined time, so that it is already located in the electromagnetic valve 2 The piston plate 21 on the shaft rod 20 can be far away from the intake passage 10 of the safety valve 1 (that is, it is in an open state), and allows the gas to flow into the safety valve 1 through the intake passage 10 of the safety valve 1 The air inlet channel 11, the air chamber 13, the air outlet channel 12 and the inside of the pipeline 3. At the same time, the gas that has been located in the air chamber 13 can push the membrane member 4...
