Through the analysis of the whole process, it can be seen that the starting valve also has a short opening process, but then it is closed, starting smoothly, Brake hydraulic motor Brake absorbs pressure pulse.

The structural principle is another kind of safety valve. By adopting throttling measures, the movable damping piston is added to the conventional direct acting safety valve to improve the performance of the valve. When Excavator hydraulic motor The pressure oil enters the valve core through the orifice, and then reaches the thrust generated by the damping piston through the orifice and the valve core channel. When the thrust reaches the pre tightening force outside the spring, it compresses the outside of the spring, making the damping piston move to the right. At the same time, the cone valve opens the overflow port, which reduces the pressure impact of the system. When the system pressure rises to the set value of the internal and external parallel springs, all cone valves open the overflow. Pressure versus time curve of the valve.
