Abstract

The invention discloses a disassembly assembly for valve parts. The disassembly assembly comprises a sleeve, a lock piece set, a pressing rod and a stud. A necking-down section is arranged at the upper end of the sleeve, a cavity is formed in the side wall of the lower end of the sleeve, a center hole penetrating through the cavity is formed inside the lower end of the sleeve, the inner diameter of the center hole is matched with the outer diameter of a valve oil seal, and the inner bottom face of the cavity forms the flange face of the center hole. The lock piece set comprises two same arc-shaped rings, the outer walls of the arc-shaped rings are in a ladder shape, the arc-shaped rings can be buckled in the center hole, and the step portions of the outer walls of the arc-shaped rings abut against the flange face. The pressing rod is a cylinder, a U-shaped groove is formed in the front end of the cylinder, a hollow protrusion is arranged on the upper surface of the middle portion of the cylinder, and a solid protrusion is arranged on the lower surface of the middle portion of the cylinder. The stud can be screwed into a bolt hole in an air cylinder cover, a threaded hole matched with the stud is formed inside the upper end of the sleeve, and the threaded hole is communicated with the center hole downwards. The disassembly assembly can selectively disassemble valve parts.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a disassembly assembly of valve parts. Background technique [0002] The valve is an important part of the engine. The function of the valve is to input air into the engine and discharge the exhaust gas after combustion. Valve parts generally include valve lock clips, upper and lower valve spring seats, valve oil seals and upper and lower inner and outer valve springs. In the field of diesel engine assembly, valve parts need to be disassembled, which usually requires complicated tools to complete. Commonly used tools include pressure plate bolts, screwdrivers, hammers, U-shaped buckles and collets, etc. These tools often have single functions and will cause disassembly damage to parts. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment...
