Product Description

 T961H high pressure feed water electric regulating valve
Product Overview: T961H high pressure water supply electric control valve in the field of industrial automation process control, by accepting the control signal output of the control unit, with the help of power operation to change the medium flow, pressure, temperature, liquid level and other process parameters of the final control element. Generally by the actuator and valve composition. If according to the stroke characteristics, the regulating valve can be divided into straight stroke and Angle stroke; According to the power used by the actuator, according to its function and characteristics, it is divided into linear characteristics, equal percentage characteristics and parabolic characteristics. Regulating valve is suitable for air, water, steam, all kinds of corrosive media, mud, oil and other media. English life control valve, control valve commonly used classification: pneumatic control valve, electric control valve, hydraulic control valve, self-operated control valve. In the automatic control of modern factories, the control valve plays a very important role. The production of these factories depends on the correct distribution and control of the flowing medium. These controls, whether it is the exchange of energy, the reduction of pressure or the simple filling of a container, require some final control element to complete. The final control element can be thought of as the "force" of automatic control. Between the low energy level of the regulator and the high level function required to perform flow fluid control, the final control element performs the necessary power amplification.
Performance Characteristics:
1, this series of valves by the valve body, seat, valve disc, pressure sleeve and valve cover composed, supporting electric actuator;
2, the valve seat and valve disc design of different structural forms, can meet the different throttling fraction and flow characteristics for linear and equal percentage of the two forms of regulation;
3, the valve body structure is Z-shaped arrangement, multi-stage throttling, high adjustment accuracy, strong versatility, for a variety of pressure difference, a variety of flow capacity under the choice of reducing warm water flow regulation.
4. Each throttle part of the valve seat and disc is made into a reasonable linear shape, which can prevent cavitation and noise, and can adjust the flow smoothly;
5, the gasket between the seat is made of flexible graphite, good compressibility, the valve is basically no leakage in the closed state, good sealing;
6, the sealing surface of the seat surfacing Co based cemented carbide, good erosion resistance;
Product features: The flow characteristics of the regulating valve, is the relationship between the relative flow of the medium flowing through the regulating valve and its opening under the condition that the pressure difference at both ends of the valve remains constant. The regulating valve is used to adjust the flow, pressure and liquid level of the medium. According to the signal of the adjusting part, the opening of the valve is automatically controlled, so as to achieve the adjustment of the medium flow, pressure and liquid level. Regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve. To introduce the electric regulating valve and pneumatic regulating valve two kinds. The regulating valve consists of two parts: electric actuator or pneumatic actuator and regulating valve. Regulation and usually divided into straight single-seat and straight two-seat two, the latter has the characteristics of large flow capacity, small unbalance and stable operation, so it is usually especially suitable for large flow, high pressure drop and less leakage occasions. Circulation capacity Cv is one of the main parameters of the control valve, the flow capacity of the control valve is defined as: when the control valve is fully opened, the pressure difference between the two ends of the valve is 0.1MPa, the fluid density is 1g/cm3, the flow number of the flow valve per hour, known as the flow capacity, also known as the flow coefficient, expressed in Cv, the unit is t/h, the liquid Cv value is calculated according to the formula.
The significance of the three injection characteristics is as follows: 1, such as percentage characteristics (logarithm) and other percentage characteristics of the relative stroke and relative flow is not linear relationship, in each point of the stroke of the change in the unit stroke caused by the change in flow is proportional to the flow of this point, the percentage of flow change is equal. So its advantage is that when the flow is small, the flow changes small, and when the flow is large, the flow changes large, that is, in different opening degrees, with the same adjustment accuracy. 2, linear characteristics (linear) Linear characteristics of the relative stroke and relative flow into a linear relationship. The change of flow rate caused by the change of unit stroke is constant. When the flow rate is large, the relative value of the flow rate is small, and when the flow rate is small, the relative value of the flow rate is large. 3, parabolic characteristics flow according to the square of the stroke proportional change, roughly with linear and equal percentage characteristics of the intermediate characteristics. From the analysis of the above three characteristics, it can be seen that in terms of its adjustment performance, the equal percentage characteristics are the best, and the adjustment is stable and the adjustment performance is good. And the parabolic characteristic is better than the linear characteristic of the adjustment performance, according to the different requirements of the use of the occasion, choose any of the flow characteristics.
