If press stroke unique place, the regulator can be divided into straight stroke and stroke; According to the actuator using power, can be divided into pneumatic control valve, electric valve, hydraulic control valve; According to its function and the special nature of the divided into linear special properties, such as percentage of special properties and parabolic special nature of the three. ( 2) The properties of linear special ( Linear) Linear relative stroke and the special properties of a linear relationship with relative flow rate. From the above three kinds of special nature of the analysis we can see that its regulation performance, in percentage of special properties such as, for optimal, its safe regulation, good regulation performance. Large flow, the flow changes in relative small, flow hour, the traffic changes in relative major. And especially the nature of the parabola, and is better than linear regulation performance of special nature, can be applied based on different occasion demands, selection that no matter what a kind of flow inside special properties. 。 Regulating valve is suitable for use in air, water, steam, all kinds of corrosive medium, mud medium of water, oil, etc. Q: electric control valve flow especially the definition of the nature of the q: regulator ( The control valve of Marine Industrial Valves) , also known as stem valve, in the field of industrial process of semi-automatic stem, after acceptance regulation unit output of stem signals, from engine operation to change medium flow rate, pressure, temperature and liquid level at the end of the stem component parameter. Electric regulating valve the flow of the nature of the special linear special properties, such as the percentage of special properties and parabolic special nature of the three. So it is the strengths of traffic hours, small flow changes, large flow, the flow rate change is big, is also on the different opening, with the same precision adjustment. Electric regulating valve the flow of a special nature, is the eternal fixed on both ends of the valve pressure difference condition, the medium flows through the electric regulating valve of the relationship between relative flow and its opening. Three kinds of fluence the nature of special significance as follows: ( 1) (percentage special properties such as Logarithmic) Relative percentage of special properties such as stroke and the relative flow rate is not a linear relationship, the stroke unit in each bit of the variation of actuating travel flow proportional to the flow of this point, the change of flow change percentage is equal. So the medium flow rate, pressure and liquid level adjustment, in order to achieve pre-set value ideal of PLC system. ( 3) Parabolic special nature of the flow according to the schedule of two proportional changes, generally with the percentage of linear and related to the nature of the special nature of the middle special. Electric control valve for regulating the flow of medium, pressure and liquid level. Unit of the variation of the flow rate change is the boot is unchanged. Ordinary consists of actuators and valves. Cv value flow experience is one of the electric control valve is mainly depending on a parameter, electric control valve flow experienced is defined as: when the electric regulating valve the whole paper, valve pressure difference on both ends of 0. 1 mpa, the fluid density degree of 1 g/cm3, per hour through the electric control valve flow number, called the flow experience, also known as the flow coefficient, to express, Cv units for t/h. Stem based on PLC system signal to adjust the opening of the valve, and a feedback now as to the PLC system, PLC system for a given signal and feedback signal, when there is deviation signal when judgment is positive or negative deviation, vote positive rotation of the motor or reverse rotation, until a given signal and feedback signal is exactly the same, just resting on motor driver. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
