Abstract
The invention discloses a kind of air compressor respirators, including pedestal, shell and filter core, the pedestal is fixedly connected with the casing, the filter core is arranged in the pedestal and shell, conduction hole is provided on the pedestal, gas vent is provided on the shell, it is characterized by: being provided with a load hole on the filter core top, it is provided with a load spool in the load hole, is connected with a spring for moving axially the load spool in the load hole in the upper end of load spool.The present invention is provided with a unloading hole on the top of filter core, excessively high pressure has just pushed up off-load spool, so that a large amount of gas is directed out discharge by the gas vent of unloading hole and case top, to make the intracorporal rapid pressure drop of case, achievees the purpose that unload safely.
Description
Technical field
The present invention relates to a kind of respirators, especially air compressor respirator.
Background technique
Existing various compressor respirators are usually to have filtering function and the relatively-stationary respirator of runner size,
Major function is to discharge the pressed gas in compressor casing body to atmosphere, so that guaranteeing will not be because various in the cabinet of compressor
Reason and make pressure rise.The defect that these respirators have jointly is exactly that filter core can be generated with the increase for using the time
Blocking must replace filter core when reaching certain use time, and otherwise respirator loses its function and compressor may be made to generate
Safety problem.
Summary of the invention
The purpose of the technology of the present invention is to solve respirator to have abnormal gas entrance under abnormality or in compressor casing body
When unloading problem, be especially adapted for use in safety problem when intracorporal to the case abnormal leakage of the inlet end of air booster.
Technical solution
The object of the present invention is achieved like this:
A kind of air compressor respirator, including pedestal, shell and filter core, the pedestal are fixedly connected with the casing, institute
The filter core stated is arranged in the pedestal and shell, is provided with conduction hole on the pedestal, sets on the shell
It is equipped with gas vent, it is characterised in that: the filter core top is provided with a load hole, is provided with a load in the load hole
Spool is connected with a spring for moving axially the load spool in the load hole in the upper end of load spool.
Respirator of the present invention, including pedestal, shell, filter core, off-load spool and spring.The shell is mounted on the base
End, is arranged filter core in shell, and the off-load spool setting is pushed down in cartridge top, and by the spring, unloaded by described
Lotus spool covers a unloading hole of filter core top setting, controls unloading for the filter core top setting by the pressure of the spring
Whether the opening in lotus hole.
The enclosure interior upper surface is provided with a location hole of the spring, the spring is arranged in the location hole of the spring
It is interior.
Belt groove is additionally provided with outside the housing tip, the gas vent setting is in the trench.
The filter core is the double-deck filter core.
O-ring seal is set between the shell and pedestal.
The present invention is provided with a unloading hole on the top of filter core, by pushing down the spring of off-load spool whether which opens
Possessed spring force determines.The size and spring force of unloading hole have determined maximum pressure when respirator works normally, when exhaling
When haustorium blocks or has gas anomaly leakage that the intracorporal pressure of case is caused to be more than the service pressure of respirator, excessively high pressure
Just off-load spool has been pushed up, a large amount of gas is made to direct out discharge by the gas vent of unloading hole and case top, from
And make the intracorporal rapid pressure drop of case, achieve the purpose that unload safely.
Present invention employs Double layer high efficient filter core, the intracorporal oil-containing gases of case can after filter element filtering when normal work
It realizes cleaning discharge outward, while can effectively prevent the impurity such as the dust in air again and entering compressor box through respirator
Interior, a small amount of lubricating oil adsorbed when work in filter core will not flow back cabinet, but concentrate and be adsorbed on filter core outer layer, be saturated to certain
It flows out, is drawn outward by the conduction hole that lower part of the housing is arranged, to ensure that the inside and outside cleaning of machine still further below when degree.
Beneficial effect
Due to using technical solutions according to the invention, respirator is effectively ensured and has realized under abnormality to compressor casing
The unloading protecting of body, and inside and outside clean-up performance when working normally compressor increases.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, pedestal, 2, shell, 3, filter core, 4, off-load spool, 5, spring, 6 unloading holes, 7, O-ring seal, 8, draw
Discharge orifice, 9, gas vent.
Specific embodiment:
See that Fig. 1, respirator of the present invention include pedestal 1, shell 2, filter core 3, off-load spool 4 and spring 5.Wherein shell 2 and pedestal 1
It is threadedly coupled, centre plus O-ring seal 7 seal, and for filter core 3 with being threadedly secured on pedestal 1, top is provided with unloading hole 6, side
Face is cylinder type double-layer filtering net.Off-load spool 4 is housed on 3 top unloading hole 6 of filter core and is pushed down by spring 5, off-load spool 4 can
It moves up and down along the cylindrical surface of 2 inside top of shell and realizes the on and off of unloading hole 6.When the gas pressure of 3 inside of filter core
Higher than setting pressure (spring force determines) when, gas pushes off-load spool 4 open upwards, directly pushes up from unloading hole 6 and shell 2
The outside direct emission of gas vent 9 in portion.
When normal work, the unloading hole 6 at 3 top of spool is to close, and gas realizes filtering emission, work by filter core 3
When filter core 3 in a small amount of lubricating oil for adsorbing will not flow back cabinet, but concentrate and be adsorbed on 3 outer layer of filter core, saturation is to a certain extent
When flow out still further below, pass through 2 lower part of shell be arranged conduction hole 8 outward draw.
