摘要：PURPOSE:To keep condary side flow rate strictly constant by locating a conical valve through a spring in pipe body. CONSTITUTION:When fluid flows in through the inlet port 9 of the valve body 20, an orifice is formed between the conical valve 19 and flow contraction cylinder 12 and the conical valve 19 becomes in equilibrium condition. Thus spring support 15 slidingly moves in the cylinder body in accordance with the pressure of the fluid, and the conical valve 19 and valve stem 17 also travels, and the spring 16 elongates or contracts being restricted between spring support 15 and flow contraction pipe 12. Therefore, by using combination of one of the contraction pipes 12 made to large, medium or small flow rate and one of the springs 16 of different spring constant, the constant flow rate valve can be ud for large range of flow.
