Abstract
The utility model discloses a special-purpose stop valve for chlorine, comprising a valve body. The lower end of the valve body is provided with an inlet channel and an outlet channel. The upper end of the valve body is provided with a valve cover. A valve stem is disposed in the valve body. A sealing filler and a pressure plate are disposed between the valve stem and the valve cover. A valve clack is disposed at the lower end of the valve stem disposed between the inlet channel and the outlet channel. The upper end of the valve stem is provided with a hand wheel. A mounting groove is disposed on the valve clack. The lower end of the valve stem is provided with a connecting head cooperating with the mounting groove. The connecting head is fixed in the mounting groove through a valve clack nut and is fixedly connected to the valve clack. The special-purpose stop valve for chlorine is advantageous in that during the installation process, the positioning between the lower end of the valve stem and the valve clack is accurate, and installation is very convenient.
