Abstract
The invention discloses a plug cock with a good sealing effect. The plug cock comprises a plug cock body and a valve rod. A valve cavity is formed in the plug cock body. Spring grooves and sealing grooves are formed in the cavity walls of the valve cavity correspondingly and communicate with the valve cavity. The sealing grooves are located above the spring grooves. A spring and a limiting plate are arranged in each spring groove. The right side of each limiting plate is fixedly connected with a limiting pin. The end, far away from the corresponding limiting plate, of each limiting pin penetrates the corresponding spring groove and is fixedly connected with a sealing plate arranged in the valve cavity. One end of the valve rod is sleeved with a fixed ring in a connected manner. The surface of the fixed ring is fixedly connected with a rotating handle. The end, far away from the fixed ring, of the valve rod penetrates the plug cock body and is fixedly connected with a top plate arranged in the valve cavity. The plug cock with the good sealing effect is simple in structure and convenient to operate, the better sealing performance is achieved for the plug cock, and the sealing effect is good; and the plug cock can be normally used when the pressure of pipeline liquid flow is high, and a better protection function is achieved for a mechanism using the plug cock.
