Description
Technical field
The utility model is related to natural gas facility field, more particularly to a kind of filter for air compressor.
Background technology
At present, compressor station yard equipment and the required clean air power source of compressor set operation are typically compressed by air
Machine is provided (clean air power source refers to that pressure is higher, and moisture free air).Such air compressor includes：Pressure
Contracting machine body, while the middle cooler, the aftercooler that are connected with the entrance of compressor body by pipeline, middle cooler rear end connects
Tape splicing has the preceding flowing line of front sewage disposal magnetic valve, rear flowing line of the aftercooler rear end connection with the dirty magnetic valve of heel row.
Using when, the air containing moisture and impurity enter compressor body entrance, with to air carry out first compression, first compression
The entrance for draining into compressor body during air afterwards is entered by pipeline after cooler cooling again carries out second-compressed, secondary pressure
Air after contracting enters supply compressor station yard equipment or compressor set after aftercooler cooling by pipeline and used.In air stream
In after cooler, contained moisture and seldom portion of air are flowed through after front sewage disposal magnetic valve by preceding flowing line in air
Discharge；After air flows through aftercooler, contained moisture and seldom portion of air flow through rear blowoff electromagnetic valve in air
Discharged by rear flowing line.As shown in accompanying drawing 2 and accompanying drawing 3, blowoff electromagnetic valve includes：Entrance valve element 6, outlet valve core 7, it is arranged on
Between entrance valve element 6 and outlet valve core 7, and for blocking or opening the valve rod 8 of entrance valve element 6.Referring to Fig. 2, when blowdown electromagnetism
When valve is opened, valve rod 8 enters 6 with entrance valve element and separated, and gas flows out from entrance valve element 6, bypasses after valve rod 8 and to be flowed through outlet valve core 7
Go out, bending gas circuit is formed in blowoff electromagnetic valve.Referring to Fig. 3, when blowoff electromagnetic valve is closed, valve rod 8 is carried out to entrance valve element 6
Closure.Two second compressions are lived through due to entering the air in rear blowoff electromagnetic valve, therefore, the air pressure in rear blowoff electromagnetic valve
It is larger, in order to avoid the air pressure that rear blowoff electromagnetic valve is born is more than the electromagnetic drive needed for the rear blowoff electromagnetic valve starts
Power, causes rear blowoff electromagnetic valve not use, it is necessary to the air pressure that blowoff electromagnetic valve is born after reduction.
Prior art makes its aperture be less than front sewage disposal valve core of the electromagnetic valve by the aperture of blowdown valve core of the electromagnetic valve after reduction
Aperture solves the above problems.Because valve element aperture reduces, the air amount of being discharged into also is reduced, held with blowoff electromagnetic valve after reduction therewith
The air pressure received, it is ensured that the normal of rear blowoff electromagnetic valve is used.
Designer has found that prior art at least has problems with：
Because the aperture of rear blowdown valve core of the electromagnetic valve is smaller, and the air containing the impurity such as dust and moisture is in the rear blowdown
Magnetic valve is interior to form bending gas circuit, extends the distance of air flowing in it, easily makes blowoff electromagnetic valve after impurity blocking
Valve element, so as to cause air compressor disorderly closedown, influences pipeline transportation operation.
