| description | The invention relates to a high-pressure difference and high-flow rate adjustable ratio control valve. A valve base is arranged in a valve cavity of a valve body; a valve core mounting hole is formed in the valve base; a valve cover is fixedly arranged on the top of the valve body in a sealing way; a sleeve is arranged in the valve cavity and is arranged above the valve base; a big valve core is moveably arranged in an inner hole of the sleeve and the valve core mounting hole of the valve base; the upper part of the big valve core is connected with a valve core sleeve; a valve rod penetrates through the valve cover; the lower end of the valve rod is connected with the big valve core; a valve core upper cavity and a valve core through hole are formed in the big valve core; the lower end of the valve rod penetrates through the valve core sleeve to be inserted into the valve core upper cavity and the valve core through hole; a driving sheet is arranged on the part, positioned in the valve core upper cavity, of the valve rod; a small valve core integrated with the valve rod is connected to the lower end of the valve rod and is arranged in the valve core through hole. The ratio control valve is characterized in that two or more threaded flowing passages with different start points are arranged on the small valve core and are provided with a plurality of cross points. The ratio control valve is novel in structure and can resist high temperature and high pressure difference, wide-range flow control can also be realized, and an adjustment curve is good. |
