摘要：PURPOSE:To prevent the abnormal pressure rise by arranging a spring at the top edge of a valve stem in a compressor stem connecting box engaged with a stem ring. CONSTITUTION:A compressor stem connecting box 51 equipped with a spring 50 interposed is installed between a stem 1 and a compressor 3. A gap DELTAH is formed on the inner surface of the compressor stem connecting box 51 so that a stem ring 52 is attached and engaged with a collar 51a, when the valve stem 1 is shifted to the valve opening side, and the spring 50 can be pressed when the stem 1 is shifted to the valve closing side. When the pressure of the fluid increases on closing the valve, the box 51 rises, and the fluid can be introduced into the inside-valve fluid side having a lower pressure.
