Description

Dual-purpose piston Technical Field The utility model relates to the technical field of pistons, in particular to a dual-purpose piston. Background The piston is a core moving part of power machines such as an internal combustion engine, a compressor and the like, is generally made of aluminum alloy or cast iron, is in a cylindrical structure, is tightly matched with a cylinder wall to form a sealed combustion chamber, the top of the piston is directly subjected to high-temperature and high-pressure gas impact generated by fuel combustion, and the skirt is connected with the connecting rod through a piston pin to convert linear reciprocating motion into rotary motion of the crankshaft. In the actual operation process of the piston, the top of the piston continuously bears direct impact of high-temperature high-pressure gas, the impact force is converted into power for driving mechanical operation through a piston connecting rod mechanism, the power is a core energy transmission link of a reciprocating power system, however, the structural strength and the bearing capacity of the piston mechanism have definite thresholds, deformation or fracture of components can be caused when the structural strength and the bearing capacity exceed the thresholds, when a power component (such as a combustion chamber of an internal combustion engine and a compression cavity of a compressor) cause abnormal rising of gas pressure due to faults (such as abnormal fuel injection and valve clamping stagnation) and the like, the traditional piston system lacks a quick pressure relief mechanism, excessive pressure cannot be discharged through an effective path in time, instantaneous high-pressure accumulation can be formed in a cylinder, the high pressure can generate impact force far exceeding the design standard on the top of the piston, top surface depression, cracks and other damages can be transmitted to related components such as a piston pin, a connecting rod and the like, chain faults are caused, and even cylinder burst is extremely threatened when the pressure component is serious, and the safety and the operation stability of the device is greatly threatened.
