を特徴とする液化石油ガス放出防止器。 The valve case is provided with a gas passage whose one end is connected to the liquefied petroleum gas container and the other end is connected to the gas pipe, and a through hole whose one end opens to the gas passage and the other end opens to the outer peripheral surface of the valve case. A valve stem with a valve body is formed in the gas passage, a slidable seat, and a spring disposed between the valve stem and the seat are inserted, and a return rod is inserted into the through hole, and the valve body is inserted into the gas passage. When the flow rate of the gas flowing through the gas passage is below a predetermined value, it opens due to the elastic force of the spring, and when it exceeds a predetermined value, it closes against the elastic force of the spring, and when the rod is pressed in the direction of the gas passage, it is closed. In a valve that is opened via a seat, a spring, and a valve stem, a recess is formed in the valve stem, and the valve case is engaged with the recess to lock the valve stem in the open position of the valve body. and a spring having an elastic force in the direction of engaging the locking member with the recess, and the locking member resists the elastic force of the spring when the pressure in the gas pipe increases after replacing the gas container. A liquefied petroleum gas release preventer, characterized in that the liquefied petroleum gas release preventer is released from engagement with the recess.
