Valve Buffer
- Mar 15, 2018 -

The invention relates to a valve buffer, using the invention, when the valve is opened or closed, the disc turns, and the connecting rod is swung, which drives the piston to move relative to the cylinder. When valve is just closed, the disc is away from the seat, the piston in the cylinder body cavity, oil can be big annular channel flow piston on the right side, the valve buffer in follow-up work status, achieve rapid close; Closed at the end of the valve disc is in the seat area, the oil flow through damping hole, and the corresponding damping effect, play a buffer action, buffers in the buffer valve working state, the buffer valve closed; At the beginning of the valve opening, the oil fluid flows to the left side of the piston through the one-way valve and the damping hole. The valve buffer is in the servo working state and can be opened quickly; at the end of the valve opening, the disc is far away from the adjacent area of the seat. The oil is flowing to the left side of the piston through the large ring channel. The valve buffer is in the servo working state and can be opened quickly.
