Behind the inner chamber of core pipe 2, finally flow through after water chamber 102 and to be flowed out by water out adapter 9.
Pressure is adjusted：Because import flow section is more than outlet flow section, core pipe 2 can be caused when inlet pressure increases
Chamber pressure increases, and now core pipe 2 can compress pressure spring 4 under hydraulic pressure effect, produce displacement and drive import overflow plug 3
Moved to the direction of pressure regulation baffle ring 103, and then reduce current flow section, core pipe is hindered by parthydraulic loss is increased
The increase of pressure in 2.Similarly, the chamber pressure of core pipe 2 can be caused to reduce when inlet pressure reduces, now core pipe 2 can be in pressure regulation
The effect of the elastic force of spring 4 produces displacement and drives import overflow plug 3 to be moved to away from the direction of pressure regulation baffle ring 103, and then increases
Current flow sections, compensate the reduction of pressure in core pipe 2, therefore, in certain pressure model by parthydraulic loss is reduced
In enclosing, it is ensured that the stabilization of pressure regulator outlet pressure.
Set pressure is adjusted：The first of pressure spring 4 can be adjusted by rotating the look nut 702 on pressure regulation end cap 7
Beginning decrement and then the pressure regulator for obtaining any preset pressure in the range of certain pressure.
Inflow-rate of water turbine is adjusted：Adjust the Flow-rate adjustment nut 801 on buckle 8 to drive whole 8 turns of core pipe by rotary current
It is dynamic so that the rectangle overcurrent mouth 203 in core pipe 2 shifts with the excessively stream axis of water chamber 102 on shell 1 so that mistake herein
Flow section changes, deflection angle（0°-90°）Bigger flow section is smaller, and corresponding flow is also smaller；Otherwise deflection angle
（0°-90°）Smaller flow section is bigger, and corresponding flow is also bigger, it is hereby achieved that the pressure regulator of different flow.
