Description

Technical Field

[0001] The invention relates to the technical field of a special machine for an oil valve seat surface, in particular to a special machine for semi-automatically knocking an oil outlet valve seat surface. Background Art

[0002] The oil outlet valve is a one-way valve. Under the action of spring pressure, the conical surface on the upper part of the valve is closely matched with the valve seat. Its function is to isolate the high-pressure oil pipe from the upper cavity of the plunger when the supply is stopped, to prevent the oil in the high-pressure oil pipe from flowing back into the injection pump. The lower part of the oil outlet valve is a cross section, which can guide and pass diesel. There is a small cylindrical surface under the conical surface of the oil outlet valve, called the pressure relief ring belt. Its function is to quickly reduce the oil pressure in the high-pressure oil pipe when the oil supply ends, to avoid oil dripping at the spray hole. When the ring belt falls into the valve seat, the upper volume increases quickly, the pressure decreases quickly, and the spray stops quickly.

[0003] Most of the oil outlet valves are clamped by a fixture and fixed on the mounting seat during processing. There is a step in the processing of the oil outlet valve to hammer the oil outlet valve to ensure its consistency and sealing.
