Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of novel hydraulic-control water valve, the water valve includes upper and lower spaced upper end cover 1 and lower end
Lid 2, is provided with a hydraulic fluid port 5 on upper end cover 1, and a delivery port 7 is provided with bottom end cover 2.In upper end cover 1 and the left side of bottom end cover 2
End is fixed with drive end bearing bracket 3 using bolt assembly, meanwhile, right-hand end is fixed with valve seat 4 using bolt assembly, on valve seat 4
It is provided with water inlet 6.Piston 8, Ke Yitong is provided with the cavity that the upper end cover 1, bottom end cover 2, drive end bearing bracket 3 and valve seat 4 are formed
