Specific embodiment
It as shown in Figure 1 to Figure 3, is a kind of exhaust valve with flow-guiding type filter device of the utility model, including valve deck 1,
Valve body 2, needle 4, float 5, attachment base 6, replys seat 7 and end cap 8 at valve seat 3, and valve seat 3, needle 4 and float 5 are set to valve body 2
Interior, float 5 is flexibly connected one end of needle 4, and end cap 8 is set to the side of valve body 2, and gasket 9 is equipped between valve seat 3 and end cap 8,
Leakproofness is improved, prevents exhaust valve from leaking air phenomenon, to guarantee the stabilization of its performance.Valve deck 1 is set respectively with attachment base 6
In the both ends of valve body 2, replys seat 7 and be set between attachment base 6 and valve body 2, valve seat 3 is equipped with exhaust outlet 10, and one end of needle 4 is set
There is sealing-plug 11, sealing-plug 11 is corresponding with exhaust outlet 10, and needle 4 is equipped with back-moving spring 12, in exhaust process, by air-flow
Percussion, float 5 rise, and needle 4 is driven to swing, and needle 4 is restored to horizontal position under the action of back-moving spring 12, passes through
Sealing-plug 11 closes exhaust outlet 10, stops exhaust；After being vented, float 5 falls, gravity and tension of the needle 4 in float 5
Sagging certain distance under the collective effect of spring 12, it is final to keep balance, it no longer moves, so that float 5 and needle 4 be avoided to fall
It falls.
It is equipped with flow-guiding type filter device 13 in valve body 2, is circumferentially evenly distributed with bolt hole on flow-guiding type filter device 13
14, to 14 drivescrew of bolt hole, flow-guiding type filter device 13 is fixed in valve body 2, improves flow-guiding type filter device 13
The stability being mounted in valve body 2, it is not easy to disengage.Flow-guiding type filter device 13 is located at the lower section of float 5, flow-guiding type filtering dress
The center for setting 13 is equipped with guide face 15, and the area coverage of guide face 15 is not less than the one third of 5 bottom area of float, guide face
15 be in bullet shape, and in exhaust process, gas effective drainage to surrounding can be reduced float by the guide face 15 of bullet shape
The area that 5 bottoms are directly impacted by high-speed gas is prevented from being flowed through the directly floating of ambassador's float 5 due to gas, leads to sealing-plug 11
Exhaust outlet 10 is closed, causes and is vented insufficient phenomenon.It is surround on flow-guiding type filter device 13 and filter hole 16, filter hole is distributed with
16 blowing angle be with 10~90 ° of horizontal sextant angle, blowing angle preferably with 30~60 ° of horizontal sextant angle, when gas passes through
It may filter that the impurity in gas when filter hole 16, the inner cavity for avoiding impurity from entering valve body 2 forms noise and abrasion float 5 etc. now
As to increase the service life of exhaust valve and guarantee the stabilization of its performance, filter hole 16 is obliquely installed, strengthens to gas
Drainage further ensures that exhaust valve is sufficiently vented.The mesh number of filter hole 16 is 4~8 mesh, and it is miscellaneous can to filter most of gas
Matter improves the filter effect to impurity in gas.
Flow-guiding type filter device 13 is located at the lower section of float 5 in the utility model, and the center of flow-guiding type filter device 13 is set
There is guide face 15, area coverage is not less than the one third of 5 bottom area of float, and guide face 15 is in bullet shape, exhaust
In the process, the guide face 15 of bullet shape can be incited somebody to action by gas effective drainage to surrounding, and through the filter hole of angled setting 16
Gas is drained to float periphery, reduces the area that 5 bottom of float is directly impacted by high-speed gas, prevents from flowing through ambassador due to gas
Float 5 directly floats, and sealing-plug 11 is caused to close exhaust outlet 10, causes and is vented insufficient phenomenon；Flow-guiding type filter device 13
It is upper around being distributed with filter hole 16, the blowing angle of filter hole 16 be with 10~90 ° of horizontal sextant angle, when gas passes through filter hole 16
When may filter that impurity in gas, the inner cavity for avoiding impurity from entering valve body 2 forms noise, reduces float 5 in exhaust process
Vibration number, extend float 5 service life, to increase the service life of exhaust valve and guarantee the stabilization of its performance, mistake
Filter opening 16 is obliquely installed, and strengthens the drainage to gas, further ensures that exhaust valve is sufficiently vented.The utility model structure
Simply, performance is stablized, noise-and-vibration-reduction, long service life, solves the problems, such as that exhaust is insufficient.
The above are only specific embodiments of the present invention, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, to solve essentially identical technical problem, essentially identical technical effect is realized, it is made
Simple change, equivalent replacement or modification etc., are all covered by among the protection scope of the utility model.
