Self pressure reducing valve


  The direct-acting pressure reducing valve is a valve that adjusts the inlet pressure to a certain required outlet pressure and relies on the energy of the medium to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttle element whose local resistance can be changed, that is, by changing the throttle area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. Then rely on the adjustment of the control and adjustment 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.
