According to adjust the valve position signal, the valve opening automatically control, so as to achieve the media flow, pressure and level adjustment. Regulating valve sub-electric control valve, pneumatic control valve and hydraulic control valve. Commonly used are electric control valve and pneumatic control valve two. Regulating valve by the electric actuator or pneumatic actuator and control valve of two parts. Control valves are usually divided into two kinds of direct-through single-seat control valve and through two-seat control valve, which has the ability to circulate large, unbalanced small and stable operation, it is usually particularly suitable for large flow, high pressure drop and leakage Less occasions. Flow capacity Cv is one of the main parameters to select the control valve, the control valve flow capacity is defined as: When the control valve is fully open, the pressure drop across the valve is 0.1MPa, the fluid density of 1g / cm3 hourly flow path Regulating valve ball valve flow number, known as the flow capacity, also known as flow coefficient, in Cv, said t / h. According to the size of flow capacity Cv check the table, you can determine the nominal valve DN. Flow characteristics of the control valve, the pressure drop at both ends of the valve to maintain a constant condition, the medium flow through the control valve and the relative flow of its relationship between the opening. Regulating valve flow characteristics of linear characteristics, such as percentage characteristics and parabolic characteristics of three. The significance of the three kinds of fluency characteristics are as follows: (1) Linearity (Linearity) Relativeness and linearity of linearity are linear. Changes in unit stroke caused by changes in the flow is unchanged. When the flow rate is large, the relative value of the flow rate changes little, and when the flow rate is small, the relative value of the flow rate changes greatly. (2) Parabolic characteristics The flow rate varies proportionately with the two sides of the travel, generally with intermediate characteristics of linear and equal percentages. From the analysis of the above three characteristics can be seen, in terms of its regulatory performance, with equal percentage characteristics for the best, stable regulation, good regulation performance. The parabolic characteristics than the linear properties of the regulatory performance is good, according to the different requirements of the occasion, select any one of the flow characteristics. (3) Equal Percentage (Logarithmic) Equal Percentage The relative and relative flow rates do not have a linear relationship. The change in flow per unit of stroke at each point of travel is directly proportional to the flow rate at that point. The percentage change in flow rate Is equal. So it has the advantage of small flow, small changes in traffic, traffic flow, the flow changes, that is, in different degrees, with the same regulation accuracy.
