Abstract
It the utility model is related to a kind of breather valve with filter, including shell body, inner housing, admission line, breathing valve body, wherein shell body, inner housing are closing housing, inner housing is located at the inside of shell body, closed cavity III is formed between shell body and inner housing, admission line is extend into inner housing, and closed cavity II is formed between admission line and inner housing, the inner space of admission line forms closed cavity I, and filter medium is provided with closed cavity II；In the bottom of inner housing circumferentially arranged with several lower steam vents, several upper air-vents are provided with the top of admission line；The air inlet of breathing valve body is connected with closed cavity III, and the air inlet of admission line is connected with tank body exhaust outlet.The utility model is arranged on down-mounting type oil tank or fuel tank, and poisonous, the harmful gas with foreign flavor of tank mouth or reservoir port discharge can be effectively filtered out while pressure release.
Description
Technical field
The utility model is related to a kind of breather valve with filter, for filter out tank mouth or reservoir port discharge have
Poison, harmful gas with foreign flavor.
Background technology
At present, environmental administration requires to fill industrial chemicals below tank body or casing（Hereinafter referred to as down-mounting type oil tank or oil
Case）.Down-mounting type oil tank or fuel tank）, jolted or the factor such as temperature because oil tank or fuel tank exist in transportation, cause oil tank
Or tank pressure increase, so needing to install breather valve on oil tank or fuel tank.Existing breather valve is while exhaust, meeting
The leakage of gas in oil tank or fuel tank is produced, so as to as mobile pollution sources, so not only pollute environment, and cause chemical industry
Peculiar smell, or even bring potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of breather valve with filter, installed in down-mounting type
On oil tank or fuel tank, poisonous, the harmful gas with foreign flavor of tank mouth or reservoir port discharge can be effectively filtered out while pressure release.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of breather valve with filter,
Including shell body, inner housing, admission line, breathing valve body, wherein shell body, inner housing is closing housing, inner casing position
In the inside of shell body, closed cavity III is formed between shell body and inner housing, admission line is extend into inner housing, air inlet pipe
Closed cavity II is formed between road and inner housing, the inner space of admission line forms closed cavity I, set in closed cavity II
There is filter medium；In the bottom of inner housing circumferentially arranged with several lower steam vents, several are provided with the top of admission line
Upper air-vent；The air inlet of breathing valve body is connected with closed cavity III, and the air inlet of admission line is connected with tank body exhaust outlet.
The filter medium is compounded to form by filter paper, glass fibre, chemical absorptive layer, cotton layer, active carbon layer.
Technique effect of the present utility model：The utility model combines decompression and filtering function together so that passes through
Poisonous, the harmful gas with foreign flavor of breather valve discharge need to first pass through filter medium in outside discharge, thus reach the mesh filtered out
's.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of breather valve with filter as shown in Figure 1, a kind of breather valve with filter, including shell
Body 6, inner housing 2, admission line 4, breathing valve body 5, wherein shell body 6, inner housing 2 is closing housing, and inner housing 2 is located at
The inside of shell body 6, forms closed cavity III 1 between shell body 6 and inner housing 2, admission line 4 extend into inner housing 2, entered
Closed cavity II 3 is formed between feed channel 4 and inner housing 2, the inner space of admission line 4 forms closed cavity I 8, closed
Filter medium is provided with cavity II 3；In the bottom of inner housing 2 circumferentially arranged with several lower steam vents 9, in admission line 4
Top is provided with several upper air-vents 7；The air inlet of breathing valve body 5 connects with closed cavity III 1, the air inlet of admission line 4
Mouth 10 is connected with tank body exhaust outlet.
The filter medium is compounded to form by filter paper, glass fibre, chemical absorptive layer, cotton layer, active carbon layer.
As shown in figure 1, to oil tank（Case）When pressure release is vented, oil tank（Case）Interior poisonous, harmful gas with foreign flavor is advanced
Enter into admission line 4, then turned back downwards by the upper air-vent 7 on admission line 4, after filter medium under
Steam vent 9 enters closed cavity II 3, and the gas after finally filtering discharges through breathing valve body 5.
