Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of hydraulic program control valve technical scheme：Including top cover set 1, valve rod 8
With valve body 10, top cover set 1 is arranged on the upper end of cushion collar 3, and the lower section of top cover set 1 is provided with upper cylinder cover 2, upper cylinder cover 2 it is upper
Side is provided with bolt 16, and the lower section of upper cylinder cover 2 is provided with cylinder 4, and cylinder 4 is internally provided with piston 15, under piston 15
