Summary:PROBLEM TO BE SOLVED: To provide a gas pressure checking device capable of reducing worker hours and capable of easily and rapidly checking both the gases in a bypass pipe when installing the bypass pipe in a gas pipe for checking work of both the gases in a protection construction or the like of gas facilities.SOLUTION: A gas pressure checking device 10 is inserted into a gas conduit 100 while being shrunk, and is expanded inside the gas conduit 100 to cut off flow of gas in the gas conduit. In the gas pressure checking device 10, a communication part 10A is formed near the center within the gas conduit 100, a first air bag 12 expanding in a hollow cylindrical shape is provided, the communication part 10A formed near the center of the first air bag 12 becomes a flow path of gas during expansion of the first air bag 12, and a second air bag 14 for cutting off the flow of gas during expansion of the first air bag 12 is provided in the communication part 10A.SELECTED DRAWING: Figure 1 【課題】 ガス設備の保安工事などに際し、両ガス確認作業の為にガス管にバイパス管を設置する場合に、作業工数を削減することが可能であるとともに、バイパス管における両ガス確認を容易且つ迅速に行うことができるガス圧力確認装置を提供することを目的としている。【解決手段】 ガス導管100内に収縮させた状態で挿入され、ガス導管100内部にて膨張させることにより、ガス導管におけるガスの流れを遮断するガス圧力確認装置10であって、ガス導管100内の中心部付近にて連通部10Aを形成しつつ、中空円筒状に膨張にする第一のエアバッグ12を有し、第一のエアバッグ12の中心部付近に形成される連通部10Aは、第一のエアバッグ12の膨張時におけるガスの流路となるとともに、連通部10Aには第一のエアバッグ12を膨張させた際にガスの流れを遮る第二のエアバッグ14が設けられている。【選択図】 図1
