6 can only occur circular motion in operating position.3 medium position of spool is equipped with retainer 13 at one, cooperates with poppet shaft 12, is used for
Verticality during keeping poppet shaft 12 to move up and down.The more complicated spool position of structure is integrally located at interior in the middle part of valve body
In gallbladder, it is coupled by adjusting handle 9 and valve body 1.
The working principle of pressure reducing valve:
The working principle of pressure reducing valve is mainly that the balance of two pressure is utilized: 1) spring is applied downwardly to the pressure on diaphragm,
So that piston driving valve rod moves down.2) diaphragm is upwarded pressure by hydraulic pressure, so that piston driving valve rod moves up.
The pressure at both sides feedback hole of spool 3 be respectively communicated with balance diaphragm 2 and valve body 1 downstream area, diaphragm by hydraulic pressure to
On pressure just from downstream hydraulic pressure.The switch of pressure reducing valve at work sets spring pressure by downstream discharge pressure and handwheel
Difference determine.
Pressure reducing valve is typically mounted on the upstream inlet of household water pipe, and the adjusting knob on adjusting handle first reaches spring
Certain decrement, different compression can balance the different discharge pressure in downstream.When user opens tap with water in rear end
When, the downward pressure for balancing 2 upper end spring 10 of diaphragm at this time is greater than the downstream discharge pressure for acting on balance 2 lower end of diaphragm,
So that piston 5 drives poppet shaft 12 to move down, the fan-shaped choke area between 3 lower end surface of spool and rotation baffle 6 increases,
Water stream channel is opened.When user is more by the unlatching of downstream tap, rear end hydraulic pressure is relatively low, acts on balance 2 lower end of diaphragm
Hydraulic pressure it is smaller, it is bigger by the flow of pressure reducing valve.
When downstream water faucet is closed, it is in the useless water stage, downstream hydraulic pressure will increase, and balance diaphragm 2 by downstream water
The effect of pressure moves up.So that piston 5 drives poppet shaft 12 to close water stream channel, at this point, downstream stable water pressure is in setting
Pressure value.The tension of the upward a little higher than spring 10 of active force of balance diaphragm 2 can be such that pressure reducing valve closes rapidly.
In useless water state, that is, stationary state, pressure reducing valve is completely closed, and is completely cut off between upstream and downstream, therefore the hydraulic pressure of upstream
Variation has no effect to downstream.
