【発明が解決しようとする課題】これは次のような欠点
があった。回収する液化冷媒ガス装置が設置されている
現場では高低差・温度差などの条件がつくりにくく時間
がかかっていた。動力による回収装置は高価で小規模業
者には負担である。現状は液化冷媒ガス使用装置撤去の
際、回収を行わず大気放出が大半である。本発明は以上
のような欠点をなくすためになされたものである。This has the following disadvantages. At the site where the liquefied refrigerant gas device to be recovered is installed, conditions such as height difference and temperature difference were difficult to make and it took time. Powered recovery equipment is expensive and burdens small businesses. At present, when the liquefied refrigerant gas use equipment is removed, most of the gas is released to the atmosphere without recovery. The present invention has been made to eliminate the above disadvantages.

きる。Embodiments of the present invention will be described below. A purge passage (3) and a discharge check joint (4) are provided inside the existing valve body, and a liquid / gas separation pipe (5) is provided to the bottom of the cylinder vessel (6). In order to use the present invention in the above structure, the socket (8) of the liquefied refrigerant gas recovery valve is attached to the cylinder cap (7). A cylinder container (6) equipped with a liquefied refrigerant gas recovery valve and a liquefied refrigerant gas device to be recovered are connected by a manifold valve, a hose, etc., and the air and liquefied refrigerant gas in the cylinder container (6) are purged and collected. The liquefied refrigerant gas is collected and collected from the lower part of the cylinder container (6) through the liquid / gas separation pipe (5) while keeping the pressure lower than that of the liquefied refrigerant gas device. In addition, when the liquefied refrigerant gas device to be recovered can be used, the liquefied refrigerant gas can be reliably returned to the liquefied refrigerant gas device to be recovered without purging without purging even if there is no power recovery device. Can be recovered.

When the liquefied refrigerant gas device can be used, it can be reliably recovered without a power recovery device. The liquefied refrigerant gas recovery valve of the present invention is inexpensive and does not impose a burden on a small-scale company, and thus is useful for improving the recovery rate of the liquefied refrigerant gas that is currently not collected and released to the atmosphere. Further, the collected liquefied refrigerant gas can be reused.
