Abstract
PURPOSE: To provide a needle valve comprising a needle part shaped in the form of an inverted cone and a stopper part formed integrally with the needle part at its upper part, which is inserted into a tubular passage for closing the passage at the stopper part at the time of emergency and controlling the flow rate of fluid having a low viscosity accurately at the needle part of the valve.
CONSTITUTION: At the top of a tubular passage 1, there is formed an enlarged opening 2. A rod 3 to be inserted into the passage 1 consists of a needle part 4 shaped in the form of an inverted cone and a stopper part 5 formed integrally with the needle part 4 at its upper part. With such an arrangement, fluid flow rate through the passage 1 can be changed widely by shifting the rod 3 in a vertical direction and thereby changing its insertion depth in the passage 1. Here, since the stopper part 5 is designed to have a larger diameter than the passage 1, fluid flow through the valve can be stopped rapidly, for instance, at the time of emergency.
