The both ends of grain are respectively equipped with filter cotton and form filter layer, and the both ends of the discoloration silica gel particle are equipped with intermediate logical with center
The netted block plate in hole is equipped with the intermediate planar metal net layer with suit through-hole on the inside of the netted block plate, is located at
An air passing space, the bottom of the air passing space and the snorkel are formed between the filter cotton and valve bottom cover of valve bottom cover side
End pipe mouth communicates, and has flow control hole on the bonnet, has stopple in the flow control hole.
The flow control hole be it is multiple, around the center annular arranged for interval of the bonnet.
The netted block plate is centrally formed protrusion, and the central through hole is formed in the protrusion, the central through hole
Inner wall and the snorkel outer wall be in close contact.
Protrusion direction after the inward-facing bending of outer circle of the netted block plate along the protrusion extends and forms loop connecting
Edge, the loop connecting are connected along with the inner wall of valve body.
The metal net layer is covered by the suit through-hole in the outside of the protrusion.
Breather valve is filtered in the utility model moisture absorption, and after moisture absorption reaches a certain amount, discoloration silica gel particle can become pink colour,
To realize that prompt uses replacement；Flow control hole can control the air mass flow passed through, prolong to greatest extent as needed
Long life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the semi-section of moisture absorption filtering breather valve；
Fig. 2 is the partial enlargement diagram of Fig. 1；
Fig. 3 is the schematic side view of moisture absorption filtering breather valve.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in figure 1 to 3, a kind of moisture absorption filtering breather valve including columned transparent valve body 1, and is mounted on valve to ginseng
The bonnet 2 at body both ends and valve bottom cover 3 are equipped with snorkel 7 in the valve body, and the snorkel is located at the valve body along axis
Center, and abut against and connect with external threaded connector 5, threaded connector 5 is mounted on the center of the bonnet side of valve body
Position, the center connecting hole on the end face of valve bonnet central bore bonnet close with valve body side is welded to connect, around institute in the valve body
The periphery of snorkel is stated filled with discoloration silica gel particle 5, the both ends of the discoloration silica gel particle are respectively equipped with filter cotton 4 and are formed
The both ends of filter layer, the discoloration silica gel particle are equipped with the intermediate netted block plate for having central through hole, including the netted gear in left side
The inside of the netted block plate 9 of disk 11 and right side, the netted block plate 11 in the left side and the netted block plate 9 in right side is equipped with centre and has
Center is set with the metal net layer of through-hole (being not shown, for being sleeved on outside snorkel 7), including left side metal net layer 12 and right side
Metal net layer 10, wherein air passing space or channel 8, the sky are formed between the filter cotton and valve bottom cover of valve bottom cover side
Gas free air space is able to achieve with the bottom end nozzle of the snorkel 7 and communicates, and has flow control hole 20, the flow on the bonnet
There is stopple 21 in control hole, the inner end of the flow control hole 20 is in contact with the filter cotton of bonnet side.
Multiple diversities arrangement that the air passing space or channel 8 can be to be evenly arranged around valve bottom cover center
Contour rib or gusset between space formed, meanwhile, also realize and the filter cotton of the end side be supported.
Specifically, in the utility model, the flow control hole be it is multiple, around the center annular interval cloth of the bonnet
