Description
Technical field
The utility model is related to air compressor machine manufacturing field, more particularly to a kind of solenoid valve of air compressor machine, more particularly to it is a kind of
Drainage exhaust solenoid valve.
Background technology
Air compressor machine is widely used in the every field of society at present, and air compressor machine at work, will produce a large amount of condensation
Water can influence to inflate efficiency and influence the normal use of downstream remaining part, also will freeze under low temperature if being drained not in time
Normal use can be seriously affected.Currently used drain solenoid valve is single-pipeline draining, and volume is larger.
Air compressor machine to before being again started up, is needed to empty the air pressure of output end, is reduced with this and opened for the first time after being stopped
Dynamic electric current and torque.Currently used air bleeding valve latus rectum is smaller, and deflation rate is low.After air compressor machine is stopped, cooling
The circulatory system will be stopped, therefore the temperature of individual part can rise rapidly.
Draining and exhaust solenoid valve common at present is individual component, for the air compressor machine of two-stage compression, needs to fill
Two sets of this products, system are excessively complicated.
Application No. is 201120159292.5 domestic utility model patent, to disclose a kind of air compressor machine secondary cylinder automatic
Release cylinder cap, including cylinder cap ontology and inlet valve, inlet valve are made of inspiration valve seat, air-breathing valve spring and suction valve chip, cylinder cap sheet
Inspiration valve seat is installed on made air inlet on body, multiple air admission holes are made in the upper end outer rim of inspiration valve seat, in inlet valve
Inlet valve spring is embedded in seat, suction valve chip is installed in air-breathing valve spring upper end.Further include unloading valve body, unloading valve spring and unloading cylinder, unloads
Carry cylinder sealing is inlaid in the cylinder cap ontology above suction valve chip, lower end stretch into made in cylinder cap ontology with inspiration valve seat institute
In the cavity of air admission hole connection processed, multiple through-holes are formed in unloading cylinder upper end, the upper of unloading valve body is coaxially embedded in unloading cylinder
End is coaxially embedded in unloading valve spring, unloads valve body lower end one between the made cylinder shape groove in unloading valve body upper end and unloading cylinder upper end
System go out can ejection suction valve chip fore-set, make a taper type protrusion, unloading above taper type protrusion in the outer rim of fore-set
It carries valve body outer rim and is formed with multiple stomatas for being connected to the cavity with the cylinder shape groove, the taper type protrusion is with feather valve
It will unloading cylinder lower ending opening closing when body up-slip.Although the exhaust of two-stage air compressor machine after power-off may be implemented in its technical solution
But it cannot exclude the condensed water of two-stage cylinder；And it since the design of its exhaust passage is straight, cannot achieve after shutting down to two-stage
The cooling effect of cylinder；Since above-mentioned technical proposal does not have electrical heating and temperature control element, when encountering extreme weather, very
It is frozen to be easy to cause equipment, can not work normally, adaptive capacity to environment is very low.Since its vent design fully relies on spring pair
The induction of air pressure easily generates mistake exhaust or exhaust clamping stagnation, leads to thrashing.Appointed due to no on the exhaust passage
What gas drier, the component being easy to cause in pipeline are corroded by steam, especially control the spring of air bleeding valve, special
It does not easily corrode, exhaust is caused to be failed.
Utility model content
The purpose of this utility model provides a kind of solenoid valve, realizes after two-stage air compressor machine powers off, smoothly by the sky of two-stage
The high pressure gas and moisture discharge system of press, high current caused by when air compressor machine can be effectively prevent to be again started up and high torque with
And water retention in the device caused by etching problem；Meanwhile it solving the heat dissipation problem after air compressor machine power-off and working as and encountering
When extreme weather, it is very easy to cause equipment frozen, can not work normally, the very low technology of adaptive capacity to environment is asked
