| description | The utility model relates to a high-pressure-difference and large-flow-adjustable-ratio control valve. A valve seat is installed in a valve cavity of a valve body. The valve seat is provided with a valve element installing hole, and a valve cover is fixedly installed on the top of the valve body in a sealing mode. A sleeve is sleeved with the valve cavity and installed above the valve seat. A large valve element is movably assembled in an inner hole of the sleeve and a valve element installing hole of the valve seat, the upper portion of the large valve element is connected with a valve element sleeve, a valve rod penetrates through the valve cover, the lower end of the valve rod is connected with the large valve element, the large valve element is internally provided with a valve element upper cavity and a valve element through hole, the lower end of the valve rod penetrates through a valve element sleeve and is inserted into the valve element upper cavity and the valve element through hole, a drive piece is arranged on the part, in the valve element upper cavity, of the valve rod, the lower end of the valve rod is connected with a small valve element integrally arranged with the valve rod, and the small valve element is installed in the valve element through hole. The high-pressure-difference and large-flow-adjustable-ratio control valve is characterized in that the small valve element is provided with two or more thread runners with different start points, and the thread runners are provided with a plurality of intersection points. The high-pressure-difference and large-flow-adjustable-ratio control valve is novel in structure and capable of being resistant to the high temperature difference and the high pressure difference, the wide range flow control can be achieved, and an adjusting curve is good. |
