Further improvement as technique scheme:
Described pilot valve and valve body at right angle setting.
The beneficial effects of the utility model are as follows:
The utility model compact structure, reasonable, working stability is reliable, adopts the design of double overflow liquid entering hole, flow velocity in the time of effectively reducing overflow when overflow, reduces the impact to overflow passage, and improves than the relief valve reliability of original single overflow feed liquor, meanwhile, relief valve spillway discharge increases greatly.
The utility model adopts one group of pilot valve to control two groups of main valves, compact structure simultaneously.During to the overflow of high-capacity pump pressure station spill valve, reduce the flow velocity of overflow liquid, meet the needs of large flow overflow, improve the stability of large flow overflow pressure regulation, extend its working life, reduce costs.
The utility model be applied to working solution must keep clean, without iron filings and other impurity, and by precision, be the filter screen filtration of 120 orders/English inch.
