66 right end of follower plate is located at 52 upside of blocking plate, if 15 gas leakage of gas transmission chamber, air pressure can reduce in gas transmission chamber 15, to make to supply gas
Gas in pipeline 10 enters in gas transmission chamber 15, so that blocking plate 52 be made to move upwards, connecting spring 50 is compressed, blocking plate 52
Movement drive follower plate 66 move upwards, thus make be lifted block 67, lifting plate 20 and lifting bar 23 rise, to make the second cone
Gear 25 is moved upwards and is detached from and the contact of first bevel gear 22；
4: when lifting plate 20 moves upwards, the work of electromagnet 73 repels each other with magnet plate 72, so that iron plate 69 is driven to move upwards,
It is directly opposite to make two pieces of magnet blocks 71, to make two pieces of magnet blocks 71 repel each other, to make left side magnet block 71 and drive shaft
24 are threadedly coupled, and motor 44 works at this time, to drive left side magnet block 71 to rise, to make driving plate 35 rise, to make
Rack bar 39 is moved upwards with support rod 31, and support rod 31, which moves upwards, moves upwards contact power supply 30, and contacts power supply 30
Energization is contacted with electric block 29 is connect, so that warning light 27 be made to light, rack bar 39 is moved upwards, to drive 38 turns of driven gear
It is dynamic, to drive driven shaft 36 to move right, to make piston 43 move right, to block connecting pipe 45 and air duct
10 connection；
5: when repairing the gas leakage situation in gas transmission chamber 15, electromagnetic switch 32 works, so that gas be made to be again introduced into gas transmission chamber
In 15, when about 52 pressure at both sides of blocking plate is equal, connecting spring 50 resets, to make blocking plate 52 reset, and electric at this time
Magnet 73 does not work, so that driving mechanism 75 be made to reset, first bevel gear 22 engages again with second bevel gear 25.
