Claims

[Scope of utility model registration request]

A control valve that simultaneously controls two water channels, such as a hot water system and a cold water system, includes a valve body, a valve stem inserted into the valve body, and a drive bar that controls the axial position of the valve stem. This drive bar is a lock nut that screws onto the valve body, and one end of the valve body is open to the outside of the valve body, and a small diameter shaft hole, a medium diameter shaft hole, and a large diameter shaft hole are coaxially connected from the back. A step-shaped shaft hole is drilled in the small diameter shaft hole, and a cold water inlet pipe is drilled between the small diameter shaft hole and the outside, and a cold water inlet pipe is bored in the inner bottom of the medium diameter shaft hole. A first annular jetty provided around the opening of the small diameter shaft hole, a cold water outlet pipe bored between the bottom surface and the outside of the first annular jetty, A hot water inlet pipe is provided between the side surface on the side of the diameter shaft hole and the outside, and the large diameter shaft hole is provided with a medium diameter shaft hole opening drilled at the bottom of the inner part of the large diameter shaft hole. A second annular jetty provided around the area, a hot water outlet pipe bored between the bottom surface and the outside of the second annular jetty, and a hot water outlet pipe screwed into the lock nut on the outer surface. The valve stem has a small-diameter shaft portion, which is loosely fitted into the medium-diameter shaft hole, and a neck portion, which is loosely fitted into the large-diameter shaft hole. It consists of a large-diameter shaft rod portion to be fitted and a first connecting portion provided at the other end, and the small-diameter shaft rod portion is fitted into the small-diameter shaft portion at a position where it abuts the first annular protrusion on its tip surface. The large-diameter shaft rod is provided with a first seal ring fitted on the middle side surface of the small-diameter shaft rod portion, and a second seal ring fitted on the middle side surface of the small-diameter shaft rod portion. A third seal ring is fitted at a position abutting the second jetty, and a fourth seal ring is fitted into an intermediate side surface, and the first connecting portion is provided with a side surface. The drive bar is provided with an insertion groove provided on the inner end surface and a notch provided on the end surface, and the drive bar has a second connecting portion that engages with the insertion groove on the inner end surface, and a male screw threaded in the intermediate portion. The locking nut is provided with a large-diameter screw hole that screws into the male thread of the valve body, and a small-diameter screw hole that screws into the male screw of the drive bar. Coaxial valve for simultaneous control.
