Abstract

A half ball valve includes a body including cavity having an assembly opening, a stem opening formed at a side of the body opposite to the assembly opening to connect the cavity and the outside, and a first connection hole inclined with respect to an axis of the stem opening. A ball is accommodated in the cavity of the body through the assembly opening to be capable of rotating to switch between an open position at which the first connection hole is open and a close position at which the first connection hole is blocked. A passage is formed in the ball inclined with respect to an axis of the stem opening and is connected to the first connection hole at the open position. Thus, the size of the ball can be reduced and, when the passage in the pipeline is blocked, the fluid flowing in the pipeline is not confined in the passage of the ball. Also, not only is dead space not formed but also the gap between the ball and the body is completely sealed by the space filler, so that the fluid flowing through the pipeline is prevented from remaining in the gap and being deposited therein. Furthermore, the full bore concept can be realized in which no difference exists between the amount of the fluid that is coming in through the inlet and the amount of the fluid that is discharged through the outlet in the ball valve installed on the pipeline.

Description

[0001] This application claims the priority of Korean Patent Application No. 2002-29297 filed at the Korean Patent Office on May 27, 2002, and Korean Patent Application No. 2002-62108 filed at the Korean Patent Office on October 11, 2002. The disclosure of the application is incorporated herein by reference in its entirety. technical field [0002] The invention relates to a hemispherical valve, in particular to a hemispherical valve installed on a pipeline for opening and closing liquid flowing in the pipeline. Background technique [0003] Typically, ball valves installed on pipes control the flow of liquid in the pipes. The ball valve opens and closes the passage of the liquid flowing in the pipeline by the rotation of the ball in the valve seat provided in the valve body. [0004] According to the type of operation, ball valves are divided into manual type and electric type. The ball valve that controls the liquid flowing in the pipeline through the ball is widely used...
