Abstract
The utility model discloses a decompression structure of a piston cylinder, which comprises a piston. A decompression spool is fixedly mounted on the piston, and a decompression oil hole is disposed on the decompression spool. A drilling structure is disposed on the spool, thereby eliminating troubles of processing two inclined holes, meeting the requirement of performance of the piston cylinder and greatly increasing production efficiency.
Description
Technical field
The utility model relates to a kind of piston cylinder.
Background technique
The list that dump truck is used can stop lifting with the piston-type hydro compressing cylinder after giving rise to design runlength, be that the pressure relief device on the piston works at this moment, and as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the pressure relief device on the piston is made of piston 1 and pressure releasing valve core 2.Be raised to behind the stroke of design pressure releasing valve core 2 when piston and push up cylinder cap and open, the high pressure oil of this moment can flow to the beam hanger chamber through two inclined holes that pressure releasing valve core 2 designs on by piston and become low pressure oil and stop motion.Two inclined hole processed complexs on the piston of present this structure interrupt drill bit easily, and work efficiency are low.
The model utility content
Technical problem to be solved in the utility model provides a kind of trouble that can fundamentally solve the processing of two inclined holes, has satisfied the piston cylinder usability, and the piston cylinder pressure relief device of enhancing productivity greatly.
For solving the problems of the technologies described above, the technical solution of the utility model is: the pressure relief of piston cylinder, comprise piston, and be installed with pressure releasing valve core on the described piston, described pressure releasing valve core is provided with the pressure release oilhole.
Owing to adopted technique scheme, the pressure relief of piston cylinder comprises piston, is installed with pressure releasing valve core on the described piston, and described pressure releasing valve core is provided with the pressure release oilhole; The structure that this spool of the present utility model is provided with boring has fundamentally solved the trouble of two inclined holes processing, has satisfied the usability of piston cylinder, and has enhanced productivity greatly.
