What are the characteristics of Low price pressure reducing valve
Low price pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, Low price pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of reducing pressure. . Then rely on the adjustment of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range. So what are the characteristics of Low price pressure reducing valve? Let's take a look at it briefly!
1. Pressure regulating range: It refers to the adjustable range of Low price pressure reducing valve output pressure P2, within which the specified accuracy is required. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring.
2. Pressure characteristic: It refers to the characteristic that the output pressure fluctuates due to the input pressure fluctuation when the flow g is a fixed value. The smaller the output pressure fluctuation, the better the characteristics of the Low price pressure reducing valve. The output pressure needs to be lower than the input pressure—the fixed value does not basically change with the input pressure.
3. Flow characteristics: It refers to the input pressure—timing, the persistence of the output pressure changing with the change of the output flow g. When the flow rate g changes, the smaller the change in output pressure, the better. Generally, the lower the output pressure, the smaller its fluctuation with the change of output flow.
The above is an introduction to the characteristics of Low price pressure reducing valve.
