The valve stem is fitted so that it can be slid relative to the other in the axial direction and is constantly biased downward by a spring, and when the valve is opened, the second valve stem moves upward as the first valve stem moves upward.
A double seal valve in which the valve body moves to follow the first valve body, characterized in that the diameter of the shaft portion where the first valve stem comes into close contact with the lower opening is approximately the same as the diameter of the first valve body. Double seal valve. (2) Claim 1 characterized in that the shaft portion of the first valve shaft extending below the first valve body is formed separately from the shaft portion above this, and the opposing ends of both shaft portions are connected to each other. Dual seal valve as described.
