A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container. In the valve block, the container valve comprises a gas filling passage in which a filling valve is installed, a gas lead-out passage in which a lead-out valve is installed, and a pressure regulator arranged at an upstream side of the lead-out valve in the gas lead-out passage. The container valve can safely supply gas under a reduced pressure for use by opening the container valve of a container whose pressure is high and gas can be filled easily into the container. The container valve can be miniaturized and the purging operation for supplying high purity gas can be performed.

1. A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container, and in the valve block the container valve comprising:a gas filling passage, in which a filling valve is installed, a gas lead-out passage, in which a lead-out valve is installed; and a pressure regulator, arranged at an upstream side of the lead-out valve in the gas lead-out passage, wherein a gas purifier is arranged at an upstream side of the pressure regulator in the gas lead-out passage, and a check valve is arranged at an upstream side of the gas purifier so as to prevent impurity from entering the gas container from the gas purifier. 2. A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container, and in the valve block the container valve comprising:a gas filling passage, in which a filling valve is installed, a gas lead-out passage, in which a lead-out valve is installed; and a pressure regulator, arranged at an upstream side of the lead-out valve in the gas lead-out passage, wherein the lead-out valve in the gas lead-out passage is a diaphragm type valve, a seat disk is connected to a diaphragm of the lead-out valve, and an opening in the seat disk serves as a purge inlet. 3. A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container, and in the valve block the container valve comprising:a gas filling passage, in which a filling valve is installed, a gas lead-out passage, in which a lead-out valve is installed; and a pressure regulator, arranged at an upstream side of the lead-out valve in the gas lead-out passage, wherein the filling valve is a diaphragm type valve.
