Specific embodiment
Embodiment 1
It is the explanation to embodiment 1 below.
As shown in Figures 1 to 6, a kind of automatic decompression type propane cylinder that can be inflated repeatedly, including gas cylinder body 1, bottle body valve
Door 2, installation external screw thread 21, valve inside valve 22, preceding bayonet 3, side bayonet 4, protection lid 5, pressure release slideway 6, pressure release venthole 61,
Pressure release block 7, sliding limiting section 71 slide outlet portion 72, are equipped with bottle body valve 2, the bottle body valve at the top of the gas cylinder body 1
2 outside of door is equipped with the installation external screw thread 21 in mating connection with outer combustion gas equipment, and inside is equipped with logical with 1 interior thereof of gas cylinder body
Valve inside valve 22, engaging when further respectively having below installation external screw thread 21 for inflating is located on the bottle body valve 2 and is filled
The preceding bayonet 3 and side bayonet 4 of gas equipment, 3 left and right sides of bayonet before the side bayonet 4 sets there are two and is located at.
The protection lid 5 includes centrally disposed mounting blocks 51 and is uniformly arranged on more on the outside of mounting blocks 51
A ratchet knob 52,51 bottom inside of mounting blocks are equipped with for the installation internal screw thread in mating connection with installation external screw thread 21
53。
Be located in the bottle body valve 2 22 side of valve inside valve be equipped with one be connected inside gas cylinder body 1 it is vertical
Pressure release slideway 6, the pressure release slideway 6 two sections slideway different using diameter, and lower section slideway diameter is sliding less than upper section
Road diameter, the upper section slideway side wall is additionally provided with the pressure release venthole 61 that multiple extensions are connected to outside bottle body valve 2, described
Pressure release block 7 include sliding limiting section 71 and positioned at the sliding outlet portion 72 of sliding limiting section 71 lower section, the sliding limit
