| description | PROBLEM TO BE SOLVED: To provide a check valve with a built-in liquid seal prevention mechanism for preventing a collecting pipe from falling in liquid sealing condition.SOLUTION: The check valves 1 with a built-in liquid seal prevention mechanism has check valves 17 operating and preventing reverse flow to LP gas containers 3, 5, 7, 9 sides when the pressure of the LP gas container 3, 5, 7, 9 sides become lower than the pressure of the collecting pipe 11 side and a pressure difference between the pressure of the LP gas containers 3, 5, 7, 9 sides and the pressure of the collecting pipe 11 side exceeds the first set value and a relief valve 19 operating and allowing the reverse flow when the above pressure difference exceeds the second set value greater than the first set value. A through-hole 29 is formed in the check valves 17 and the relief valve 19 has a valve body 31 movably arranged in the through-hole 29 of the check valves 17. The valve body 31 is located so as to seal one end of the through-hole 29 when the above pressure difference does not exceed the second set value and moves in a direction opening the one end of the through-hole 29 when the above pressure difference exceeds the second set value. |
