摘要： A method of opening a fluid control valve having a housing externally fitted onto a fluid pipe in a hermetic state and a valve body configured for contacting an inner peripheral surface of a hole of the fluid pipe provided in the housing and an inner peripheral surface of the fluid pipe to hermetically block or open a flow of fluid in the fluid pipe. The method includes a pressure adjustment step of decreasing a pressure difference between the fluid in the fluid pipe on a first side of the valve body and the fluid in the fluid pipe on a second side of the valve body in a blocking state of the valve body. The first side and the second side of the valve body are arranged so as to sandwich the valve body in an axial direction of the fluid pipe, and a valve opening step of opening the valve body.
