Abstract
The utility model discloses a railway freight car control valve air dust filter, the equipment of air dust filter is in the railway freight car control valve, air dust filter includes the seal cover and by straining the rectangular shape passageway formula filtration that net enclosure becomes, the tip is connected with the seal cover before the rectangular shape passageway formula filtration be provided with the inside air inlet that communicates of passageway with rectangular shape passageway formula filtration on the seal cover, the seal cover passes through sealing member and control valve body sealing connection, by the air inlet incoming air of seal cover inside entering into the control valve after rectangular shape passageway formula filtration. The utility model discloses a filtration of passageway formula substitutes original filter screen structure, and effectual filter area and the filter fineness of having increased does not have the inner frame in addition in the filtration, large -minded thoroughly, and the dirty volume of receiving is big, and durable can guarantee to advance the inside air quality of entry control valve than using under the rugged environment.
Description
Technical field
The utility model belongs to rolling stock technical field, more particularly to a kind of railway freight-car control valve air filter dirt dress
Put.
Background technology
At present, using 60 ~ 80 mesh copper mesh or steel mesh filter dirt more than railway freight-car air shut-off valve filter.Due to China
Railway freight-car running environment is more severe, and the filter effect for adding dirt filtrating screen is relatively limited so that some air in each reservoir
Impurity and rust dirt readily penetrate through dirt filtrating screen and cause guiding valve pair to be pulled in the secondary working face of brake valve guiding valve sews, or enters system
Gas circuit is blocked in dynamic valve gas circuit, the performance of brake valve is affected, in addition moisture convergence is also easy to produce corrosion at filter screen in pipeline.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind can effectively increase filtration
Area and filtering accuracy, it is ensured that enter the railway freight-car control valve air dust filtration device of control valve inner air quality.
What the technical solution of the utility model was realized in：A kind of railway freight-car controls valve air dust filtration device, described
Air dust filtration device is assembled in railway freight-car control valve, it is characterised in that：The air dust filtration device include sealing shroud and
The strip channel-type filtration surrounded by filter screen, the strip channel-type filtration leading section is connected with sealing shroud,
The air inlet connected with the channel interior of strip channel-type filtration is provided with the sealing shroud, the sealing shroud leads to
Cross seal to be tightly connected with control valve body, the air entered by the air inlet of sealing shroud is being filtered through strip channel-type
Enter into after structured filter inside control valve.
Railway freight-car described in the utility model controls valve air dust filtration device, and it filters in the strip channel-type and ties
The tail end face of structure is provided with sintering net filter film, and the sintering net filter film is connected with cuff, and the cuff is socketed in strip and leads to
The afterbody of road formula filtration.
Railway freight-car described in the utility model controls valve air dust filtration device, and its described filter screen is by stainless steel material system
Into.
Railway freight-car described in the utility model controls valve air dust filtration device, its described strip channel-type filtration
Overall annular in shape, the strip channel-type filtration is surrounded by the filter screen with continuous folding formula structure.
Railway freight-car described in the utility model controls valve air dust filtration device, and its described filter screen is single layer structure or many
Rotating fields, when the filter screen is sandwich construction, the filter bores interlaced arrangement on adjacent two layers filter screen.
The utility model substitutes original filter structure using the filtration of channel-type, effectively increase filter area and
Without inner frame in filtering accuracy, and filtration, Air permenbility is big, and pollutant holding capability is big, durable in use, can be in relatively rugged environment
Under use, it is ensured that enter control valve inside air quality.
Description of the drawings
Fig. 1 is structural representation of the present utility model.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As illustrated in fig. 1 and 2, a kind of railway freight-car controls valve air dust filtration device, and the air dust filtration device is assembled in iron
In the Control Valves for Freight Cars of road, the air dust filtration device includes sealing shroud 1 and filters knot by the strip channel-type that filter screen is surrounded
Structure 2, the filter screen is made up of stainless steel material, and the leading section of strip channel-type filtration 2 is connected with sealing shroud 1,
The air inlet 3 connected with the channel interior of strip channel-type filtration 2, the sealing shroud 1 are provided with the sealing shroud 1
It is tightly connected with control valve body 5 by seal 4, is provided with the tail end face of the strip channel-type filtration 2
Sintering net filter film 6, the sintering net filter film 6 is connected with cuff 7, and the cuff 7 is socketed in strip channel-type filtration 2
Afterbody, the air overwhelming majority entered by the air inlet 3 of sealing shroud 1 is filtering laggard through strip channel-type filtration 2
Enter to inside control valve, extremely least a portion of air filters laggard via the sintering net filter film of strip channel-type filtration afterbody
Enter to inside control valve.
Wherein, the strip channel-type filtration 2 is overall annular in shape, and the filter screen is that single layer structure or multilayer are tied
Structure, when the filter screen is sandwich construction, the filter bores interlaced arrangement on adjacent two layers filter screen, the strip channel-type is filtered
Structure 2 is surrounded by the filter screen with continuous folding formula structure, and by pleated structure filter area is increased, and improves filtering accuracy.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
