Description

[Brief explanation of drawings]

Figures 1 to 3 show an embodiment in which a shutoff valve locking device is applied to a high-pressure gas container valve equipped with a shutoff valve operated by excess gas. FIG. 2 is a partially cutaway sectional view showing the state, FIG. 2 is a partially cutaway sectional view showing the overflow cutoff state, and FIG. 3 is a partially cutaway sectional view showing the shutoff valve locked state when inverted. Figures 4 and 5 show other embodiments in which a shut-off valve locking device is applied to a high-pressure gas container valve equipped with a shut-off valve operated by the swing of a weight, and Figure 4 shows normal operation. FIG. 5 is a partially cutaway sectional view showing a state in which a flow rate is used, and FIG. 5 is a partially cutaway sectional view showing a cutoff state. Figure 6 is a plan view of the locking device shown across the valve body in the embodiments of Figures 1 and 4; Figures 7, 8, and 9;
This figure is a plan view of a modified example of the locking device shown in the same manner as FIG. 6, and FIG. 10 is a sectional view of a modified example of the locking device. 1: Valve body, 3: Discharge path, 4: Inflow path, 5: Main valve seat, 8

Claims (1)

[Scope of Claim for Utility Model Registration] A sub-valve seat consisting of an enlarged diameter step is formed on the upstream side of a main valve seat provided at the upper end edge of an inflow passage communicating with a discharge passage of a valve body attached to a high-pressure gas container, A valve for a high-pressure gas container in which a shutoff valve that automatically closes the auxiliary valve seat in the event of a disaster is built into the inflow passage, and a ball guide member that allows gas to flow is provided in the valve stem of the shutoff valve, A lock ball is irremovably stored in a hole storage space formed vertically between the ball guide member and the inflow path, and the lock ball disables the shutoff valve when the high pressure gas container is overturned. A shutoff valve locking device for a high-pressure gas container valve, characterized in that it locks.
