Embodiment
Below in conjunction with accompanying drawing overall structure of the present utility model is described further.
As shown in Figure 1, Y type magnetic levitation resistance-reducing control valve for water pump, comprise valve body 1, oil hydraulic cylinder 8, diaphragm 14, piston rod 10, magnetic suspension assembly 5, big valve flap 3, little flap 4 and valve seat 2, the described big valve flap 3 that has relief hole is sleeved on the piston rod 10 that little flap 4 and magnetic suspension assembly 5 are housed, and the Slow Close mechanism that forms with piston rod 10, diaphragm 14 moves, 5 pairs of big valve flaps 3 of described magnetic suspension assembly apply a magnetic attraction that makes progress, and the active force of 3 pairs of current of big valve flap is reduced.
Above-mentioned magnetic suspension assembly 5 is made up of magnetosheath 5-1 and the metalwork 5-2 that is enclosed within the magnetosheath 5-1, and wherein magnetosheath 5-1 is fixed on the piston rod 10, and metalwork 5-2 is fixed on the big valve flap 3.
Above-mentioned valve body 1 and oil hydraulic cylinder 8 have constituted an airtight fluid passage, oil hydraulic cylinder 8 is fixed on the valve body 1 by valve gap 9, diaphragm upper press ring 13, pressure ring 15 is positioned at oil hydraulic cylinder 8 under diaphragm 14 and the diaphragm, and with piston rod 10, magnetic suspension assembly 5 and the little flap 4 affixed component movement assemblies that are integral, big valve flap 3 is enclosed within on the piston rod 10, on the valve seat 2 affixed valve bodies 1, penstock 6 two ends that modulating valve 7 is housed are communicated with the entrance point of valve body 1 and the bottom of oil hydraulic cylinder 8 respectively, and water output duct 12 two ends that maintenance valve 11 is housed are communicated with the outlet end of valve gap 9 and valve body 1 respectively.
The magnetic attraction direction that 5 pairs of big valve flaps of above-mentioned magnetic suspension assembly 3 produce makes progress, and the magnetic attraction size is slightly less than the poor of the deadweight of big valve flap 3 and its buoyancy in hydrostatic.
In conjunction with the accompanying drawings the utility model working procedure is done and is specified:
Behind starting mode of pump, Y type magnetic levitation resistance-reducing control valve for water pump makes oil hydraulic cylinder 8 bottoms produce pressure by penstock 6, diaphragm 14 moves on common together with piston rod 10, little flap 4 and magnetic suspension assembly 5 etc. under pressure, 3 of big valve flaps are removed under the acting in conjunction of magnetic suspension assembly 5 and current and are opened, then flow out oil hydraulic cylinder 8 gradually by the water in valve gap 9 and the oil hydraulic cylinder 8 common oil hydraulic cylinder epicoeles of forming by water output duct 12, when diaphragm 14 and assembly thereof rise to top dead center, valve wide open, big valve flap 3 also rises to the design peak, the abundant overcurrent of valve; Normally in service, 5 pairs of big valve flaps 3 of magnetic suspension assembly apply a magnetic attraction that makes progress, and this magnetic attraction is slightly less than the poor of the deadweight of big valve flap 3 and its buoyancy in hydrostatic.
