Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As depicted in figs. 1 and 2, comprising: outer valve 1, inner valve body 2；Outer valve deck 14, outer valve are equipped at the top of the outer valve 1
Lid 14 is equipped with outer vent 16；Air filtering core 13 is equipped in the valve chamber of the outer valve 1, which is existing precision
Air filtering core can carry out secondary filter to air；The air filtering core 13 has hollow cavity；The inner valve body 2 is set to
In the hollow cavity；Interior valve deck 12 is equipped at the top of the inner valve body 2, interior valve deck 12 is equipped with inner vent；The inner valve body 2
Valve chamber in be equipped with float 10, float 10 can move up and down in 2 valve chamber of inner valve body；Specifically, float 10 can float
On bubbling through the water column, when the water level in inner valve body valve chamber rises, float 10 is moved upwards with water level；When in inner valve body valve chamber
When water level decreasing, float 10 is moved downward with water level.When the float 10 is located at the top of 2 valve chamber of inner valve body, float
Son 10 forms sealing pair with the interior valve deck 12.Float 10 is adapted with interior valve deck 12, in float 10 rises to water level
When valve body valve chamber top, the inner vent that internal valve covers can be closed, and when float 10 is located elsewhere, inner vent is beaten
It opens.The import of the inner valve body 2 is set in the import of the outer valve 1；The import of the outer valve 1 is connected by adapter 9
Tap into gas nozzle 3；It is provided with strainer 4 in the suction nozzle 3, the air of entrance is further filtered；3 upper end of suction nozzle and outer
Valve body is additionally provided with spring 6 between 1 import lower end.When air pressure is larger in pipe network, need to be vented when, spring 6 is in compressive state；When

Since the spool of existing micro-exhaust valve mostly uses metallic copper to make greatly, for a long time using being easy to cause heavy metal
It is precipitated, influences water quality safety, therefore, in the present embodiment, the outer valve 1, outer valve deck 14, inner valve body 2, interior valve deck 12 and other
The material of component of paddling is all made of 304 stainless steel materials.304 stainless steels have outstanding high temperature resistant and corrosion resistance characteristic, extensively
Applied to food, medical industry.
As shown in figure 3, the exhaust process of the present embodiment are as follows: when having air spilling in pipe network, air is through suction nozzle and strainer
Into inner valve body valve chamber, with increasing for inner valve body valve chamber upper air, pressure rises, float with water level under pressure
It moves downward, opens inner vent；Air is discharged from inner vent, and after air filtering core, into outer valve, eventually by
Outer vent discharge on outer valve deck.Exhaust finishes, and inner valve body valve cavity pressure restores normal, makes in inner valve body valve chamber on water level
It rises, float also moves upwards therewith, closes inner vent.
As shown in figure 4, the breathing process of the present embodiment are as follows: when generating negative pressure in pipe network, under the water level in inner valve body valve chamber
Drop, float move downward therewith, open inner vent, since ambient atmosphere pressure ratio ductwork pressure is big at this time, outside air
Outer valve valve chamber can be entered by outer vent, and after air filtering core carries out secondary filter, entered by inner vent in
Valve body valve chamber, and then suction nozzle and strainer are entered by adapter and further filtered, it carries out filtered twice external empty
Gas eventually enters into inside pipe network.Air-breathing finishes, and inner valve body valve cavity pressure restores normal, increase water level in inner valve body valve chamber,
Float also moves upwards therewith, closes inner vent.
Micro-exhaust valve provided by the utility model with air filtration is provided with two layers of valve body --- outer valve and internal valve
Body, and air filtering core is provided between two layers of valve body, in exhaust, the air in pipe network enters micro-exhaust valve through suction nozzle
Inner valve body, and after air filtering core filters, it is discharged by outer valve；For micro-exhaust valve in air-breathing, outside air is through outer vent
Into outer valve, and after air filtering core filters, into inner valve body, most enter pipe network through suction nozzle afterwards, due to setting in suction nozzle
There is strainer, therefore the air of entrance can further be filtered.In addition, being all made of screw thread company between all parts of the utility model
Connect so that installation, disassembly process it is very convenient.As it can be seen that technical solution provided by the utility model, it can be in entrance pipe network
Outside air filtered twice, removes dust and bacterium in outside air, and then guarantees the water quality safety in water-carriage system,
And it is convenient for disassembly and assembly.The utility model is particularly suitable in the water-carriage system of direct drinking.
