When pressure inside liquefied gas bottle 2 is greater than the unlatching setting value of primary safety valve for inner container 15, which is opened
It opens, the gas medium inside liquefied gas bottle 2 can be entered primary safety valve for inner container 15 by level-one safety line 16 and by a level security
Valve 15 is discharged, to carry out pressure release to liquefied gas bottle 2.Thus lost in the failure of automatic valve 12, generation blocking or in vacuum
When the particular surroundings such as effect, fire, primary safety valve for inner container 15 can guarantee going on smoothly for pressure discharge operations.
In the present embodiment, automatic valve 12 and primary safety valve for inner container 15 pass through two independent pipelines and liquefied gas bottle respectively
2 connections can further improve the whole safety of liquefied gas bottle releasing pressure automatically system 1.
Preferably, in the present embodiment, the unlatching setting value of primary safety valve for inner container 15 is greater than the default of the unlatching of automatic valve 12
Value, such setting automatic valve 12 can start prior to primary safety valve for inner container 15 in 2 superpressure of liquefied gas bottle and carry out pressure release, can
Guarantee pressure discharge operations safety and timeliness.When 2 pressure of liquefied gas bottle it is excessive and beyond automatic valve 12 pressure relief capability or
In the case that automatic valve 12 fails, it can also assist carrying out pressure release by primary safety valve for inner container 15, further increase safety.
As shown in Figure 1, the liquefied gas bottle releasing pressure automatically system 1 of the present embodiment further includes control switch 17.Control switch
17 are electrically connected with control module 13, to control the opening and closing of automatic valve 12.Hypertonia in liquefied gas bottle 2
When, the unexpected take-off of automatic valve 12 in order to prevent can open or close automatic valve 12 by manually adjusting control switch 17,
To stablize the pressure in liquefied gas bottle 2 in reasonable pressure limit, to enhance the safety of system.
In addition, the automatic valve 12 of the present embodiment can be electrically-controlled valve, solenoid valve or motor-driven valve.Pressure inductor 11 may be used also
To replace with pressure sensor or pressure switch.
Liquefied gas bottle releasing pressure automatically system embodiment 2
