Embodiment：
A kind of step piston flow regulating valve, as shown in Figure 1, including main valve body 3, valve rod 8, main valve body 3 is interior to be equipped with spherical crown chamber 31,
Formed with runner 32 between spherical crown chamber 31 and main valve body 3；The left side of main valve body 3 is connected with end valve body 1；Runner 32 and end valve body 1
Inner cavity communicate；One end of valve rod 8 is connected through main valve body 3 with the crank 7 in spherical crown chamber 31；Connecting rod is connected with crank 7
6, the end of connecting rod 6 is connected with step piston 5；Valve rod 8 drives crank 7 to rotate, and then realizes that connecting rod 6 drives step piston 5 dynamic
Make so that step piston 5 is connected or is separated with the inner cavity of end valve body 1, be mutually separated so as to fulfill end valve body 1 and main valve body 3 or
It is connected；Step piston 5 includes the first rank piston body D1, the diameter of second-order piston body D2, the first rank piston body D1 are more than the
The diameter of second order piston body D2, the first rank piston body D1 and second-order piston body D2 form stepped；First rank piston body D1 with
Valve tune stream section L1 in spherical crown chamber 31 is engaged；Positive stop lug boss 33, positive stop lug boss 33 and second-order are equipped with spherical crown chamber 31
Piston body D2 is engaged, the stroke limit for the first rank piston body D1.
In the present embodiment, the valve seat 2 that passes on left of main valve body 3 is connected with end valve body 1 so that step piston 5 and 2 phase of valve seat
