Abstract

This invention regards a needle valve. It is composed of a main body, an adjusting element and a steel ball. There are two flow ducts inside the main body, one at each end of the main body. A connector element is set in between the two ends of the main body. There is a containing room inside the connector element to communicate the two flow ducts. A valve base, part of the containing room, is formed at the place where two flow ducts meet together. An adjusting element with a needle push head at one end is set inside the containing room with the position-adjusting capability in the axial direction. The needle push head could reach a place inside the valve base. A turning wheel at the other end of the adjusting element is set to adjust the position of the needle push head. A steel ball located inside the valve base could be pushed by the needle push head for a perfect sealing. Macro-photographing lens
