Abstract
A stop valve for water pipes includes a body, and a valve block. The body has a through hole extending from one end to other, and a cylindrical holding hole on one side to communicate with the through hole. The valve block has a transverse hole, and is disposed in the cylindrical holding hole so that water can flow through the through hole when the valve block is open where the transverse hole is aligned with the through hole of the body. In addition, the valve block is formed with a cylindrical shape so that it can be stably held in position by means of those portions of the body that define the cylindrical holding hole to secure a tight contact of the valve block with a leak-prevention ring equipped around one inner end of the through hole.
