Main Technical Parameters

Working Principle

As shown in the figure, the medium at the inlet end flows into the upper cavity of the diaphragm 05 of the main valve through the catheter 08 and the needle valve 09, and then passes through the pressure reducing valve 10 and ball valve 12 outflow, at the same time the inlet end of the medium pressure will open the main valve disc 03, the inlet end of the medium from the main valve disc 03 flow after entering the valve. The pressure after the main valve rises, the medium pressure acting on the lower cavity of the pressure reducing valve 10 diaphragm increases, and the pressure reducing valve10 valve the flap opening is reduced, the medium flowing out through the pressure reducing valve 10 and the ball valve 12 is reduced, and the pressure in the upper cavity of the main valve diaphragm 05 rises and pushes down. The main valve disc 03 is moved, the opening degree of the main valve disc 03 is reduced, and the pressure after the main valve is reduced. The pressure after the main valve is reduced, and the effect is in the medium pressure of the lower cavity of the diaphragm of the pressure reducing valve 10 decreases, and the disc opening of the pressure reducing valve 10 increases, and flows out through the pressure reducing valve 10 and the ball valve 12 the medium increases, the pressure of the upper cavity of the
main valve diaphragm 05 decreases, and the inlet medium pressure pushes the main valve disc 03, the main valve the opening degree of flap 03 increases, and the pressure after the main valve increases until the pressure after the main valve reaches the set value. If the main valve is not after the valve, the medium is not flow, the pressure after the main valve continues to rise, the pressure reducing valve 10 valve disc opening continues to decrease until closed, the main valve diaphragm 05 on the cavity pressure rises, push the main valve disc 03 downward, and the opening degree of the main valve disc 03 decreases until it is closed. The Pressure after valve adjustment method: Turn the adjusting screw 11 clockwise, increase the outlet pressure of the pressure reducing valve 10, and the outlet pressure of the main valve enlarge. Turn the adjusting screw 11 counterclockwise, the outlet pressure of the pressure reducing valve 10 decreases, and the outlet pressure of the main valve decreases.
