Abstract
The utility model discloses a piston type load-reducing silencer of an air compressor, which comprises a load-reducing valve body and a silencer combined on the load-reducing valve body, wherein the load-reducing valve body is provided with an air outlet which is connected with an air inlet of the air compressor and an air inlet of a pressure regulating valve which is connected with an air storage cylinder, the silencer comprises a cover shell and a filter core arranged in the cover shell, and a silencing air inlet is arranged on the cover shell. The utility model is characterized in that a valve core cavity is arranged at the tail end of a passage connected with the air inlet of a pressure regulating valve, a valve core is arranged in the valve core cavity, the upper end surface of the valve core is a sealing surface, and a corresponding pre-opened opening is arranged at the upper end of the sealing surface of the valve core. The utility model has the advantages of no spring, novel structure, simplicity, practicality, reasonable and artful design, stable and reliable operation, long service life and low cost.
Description
Technical field:
The utility model relates to the machinery parts, is off-loading and silencer on a kind of air compressor, specifically, is a kind of piston type air compressor unloaded silencer.
Background technique:
Air compressor is to use mechanical widely standard equipment, especially piston type air compressor, the power equipment that generally uses of all trades and professions especially, and on these piston type air compressors, generally using a large amount of unloaded silencers at present.The existing unloaded silencer of this class generally is to adopt the easing valve of band spring reset structure and the combination of common silencing apparatus, and structure is comparatively complicated, and also comparatively heavy, cost is also higher relatively, also has certain problem in addition in reliability with on working life.
Summary of the invention:
It is simple that the purpose of this utility model provides a kind of non-spring structure, move reliable and stable, long service life, the piston type air compressor unloaded silencer that cost is low.
Technical solution of the present utility model is: a kind of piston type air compressor unloaded silencer, off-loading valve body and the silencing apparatus that is combined on the off-loading valve body are arranged, the air outlet that is connected with the air compressor intakeport is arranged on the off-loading valve body, with the pressure regulator valve suction port that is connected with gas receiver, silencing apparatus comprises the filter core in case and the case, the noise elimination suction port is arranged on the case, it is characterized in that: the channel end that is connected with the pressure regulator valve suction port has spool chamber, spool is housed in the spool chamber, the spool upper-end surface is a sealing surface, and the valve core sealed cover upper end has corresponding waiting to open and close mouth.
Valve core sealed cover described in the utility model upper end is pairing waits to open and close mouth and is positioned on the valve gap that is contained in the valve body upper end, and the upper end of valve gap and silencing apparatus case are fixed.Spool is a cup-shaped or cylinder, and the top edge of expansion is arranged; On the upper end sealing surface of spool Sealing is arranged.The pressure regulator valve suction port is positioned at the valve body outer side surface.
The beneficial effects of the utility model are: non-spring structure is novel unique, and is simple and practical, and it is ingenious reasonable design, move reliable and stable, long service life, cost is low.
