Liquefied petroleum gas is used as fuel, and has high heat value, no smoke and no carbon residue, and is convenient in operation and use, and has been widely used in the life field of people. The bottled supply is to distribute the liquefied petroleum gas to each household from a storage station through a sealed steel bottle as a gas supply source of the household kitchen range. Liquefied petroleum gas is a toxic gas, but volatilization of this toxicity is conditional. Only when the concentration of the liquefied petroleum gas in the air exceeds 10%, the toxicity which causes the human body to react can be volatilized. When a human body is exposed to such toxicity, vomiting, nausea and even coma occur, and great damage is brought to the human body. The liquefied petroleum gas is also very easy to flow, and once leakage occurs, the liquefied petroleum gas flows out of the storage.

Principle of operation
Referring to fig. 1 to 9, when the liquefied gas starts to be used, when the liquefied petroleum gas in the first sealed space 230 of the inner tank shell 202 is more, the pressure of the space in the tank is larger, the piston plate 203 is propped up, but the piston plate 203 cannot be directly propped on the top of the inner tank shell 202 due to the compressed air in the second sealed space 231, when the pressure of the liquefied gas in the first sealed space 230 is gradually reduced, the piston plate 203 gradually slides down, the content of the first sealed space 230 is reduced, the pressure is maintained, the liquefied gas in the first sealed space is ensured to have enough pressure until the piston plate 203 slides to the bottom of the inner tank shell 202, and the liquefied gas in the first sealed space is completely used.
When the liquefied gas enters the detection channel 302 from the second circular channel 111, the gas drives the fan blades 303 to rotate, the fan blades 303 drive the fan gear 304 to rotate, the fan gear 304 drives the detection gear 308 meshed with the fan gear 304 to rotate, the detection gear 308 drives the display gear set 309 to rotate, and the display displays the reading of the liquefied gas.
When leakage occurs between the inner layer and the outer layer of the liquefied gas tank, the handle 4 is grasped to rotate the outer layer tank shell 201, so that leakage notches on the outer layer tank shell 201 and the inner layer tank shell 202 are staggered with each other and are temporarily closed, meanwhile, the top outlets of the meshed semicircular grooves 207 on the inner wall of the outer layer tank shell 201 are separated from the covering shielding of the partition plates 206, the stored strong-effect glue in each storage space 204 flows from top to bottom through the meshed semicircular grooves 207, contacts with air at the leakage notches, is quickly solidified, and thoroughly closes a gap between the outer layer tank shell 201 and the inner layer tank shell 202, so that secondary leakage is prevented.
When the pressure reducing valve 1 is closed, the first semicircular rack 108 is located in the first through pipe 103, the circular blocking block 110 on one side is blocked in the first circular channel 109, the second semicircular rack 112 is located in the second circular channel 111 and the air outlet channel 229, the circular blocking block 110 on one side is blocked in the air outlet 220, the liquid in the pressure reducing channel 228 and the second rubber hose 223 does not squeeze the pressure reducing port 222, the pressure sliding block 224 is squeezed on the rightmost side of the pressure channel 225 by the liquefied gas with pressure, the first through hole 221 is not communicated with the upper air outlet 220 and the lower first channel 226, and the liquefied gas in the first sealed space 230, the first rubber hose 210, the pressure reducing channel 212 and the first channel 226 is in an equilibrium state.
Rotating the control wheel 101, the gear 107 drives the first semicircular rack 108 to move in the downward decompression channel 228 of the first circular channel 109, liquid in the decompression channel 228 and the second rubber hose 223 is extruded to move in the decompression port 222, the pressure slide 224 is pushed to move in the direction of the pressurizing port 217 until the first through hole 221 is communicated with the upper air outlet 220 and the lower first channel 226, the gear 107 simultaneously drives the second semicircular rack 112 to move upwards in the second circular channel 111 and the air outlet channel 229, the circular blocking block 110 on one side is separated from the air outlet 220, liquefied gas enters the air outlet 105 from the first sealing space 230 through the second opening 209 and the first rubber hose 210 to extrude the decompression block 214 and the spring 213 in the decompression channel 212, the branch pipe first channel 226 entering the decompression channel 212 enters the first through hole 221, the air outlet 220, the third rubber hose 216, the air outlet 229 and the second circular channel 111 which are in a communicating state, and the liquefied gas enters the air outlet 105 from the detection channel 302 to complete decompression when the control wheel 101 is continuously rotated until the detection channel 302 is communicated with the second circular channel 111.
The control rotating wheel 101 is reversely rotated, the gear 107 drives the first semicircular rack 108 to move towards the first circular channel 109 above the decompression channel 228, liquid in the decompression channel 228 and the second rubber hose 223 is pulled to move away from the decompression opening 222, the pressure sliding block 224 moves towards the decompression opening 220 due to the pressure of liquefied gas until the pressure sliding block 224 is propped against the circumference of the decompression opening 220, the gear 107 simultaneously drives the second semicircular rack 112 to move towards the air outlet channel 229, the detection channel 302 and the second circular channel 111 are disconnected, the control rotating wheel 101 continues to rotate, the gear 107 drives the circular blocking block 110 on one side of the second semicircular rack 112 to move towards the air outlet 220, the liquefied gas in the air outlet 220, the third rubber hose 216, the air outlet channel 229 and the second circular channel 111 is re-extruded back into the first through hole 221 and the first channel 226, the problem of residual liquefied gas in the pipeline during closing is solved, and meanwhile, the first through hole 221 is disconnected from the first channel 226 and the air outlet 220 to complete the closing process.
