Description
Technical field
A kind of binary channels dust-proof air ventilation plug of the utility model, belongs to porous plug technical field.
Background technique
Gear-box is widely applied as important transmission parts with high-power, big load mechanical equipment, and gear-box is being transported
During row, case internal gear lubricating oil temperature can reach 70 degree or more, and oil temperature raising causes grease viscosity to decline, and gas is swollen in case
It is swollen, it is therefore desirable to porous plug to be installed on cabinet, it is inside and outside that gear-box has been effectively ensured in gear-box operational process in porous plug
Pressure balance prevents gear-box permeability, avoid because gear-box air pressure inside it is excessively high caused by sealing element damage.
Environment inside and out gear-box is directly connected in the air hole of existing porous plug, i.e. air inlet and exhaust is logical for one
Road causes the impurity such as the dust in external environment to be easy to enter inside gear-box by air hole, causes to gear lubricant
Pollution, due to being a channel, causes exhaust to have some setbacks further such that internal bearings, gear failure, accelerate oil loss.
Utility model content
The utility model overcomes the shortcomings of the prior art, and providing a kind of air inlet and exhaust is autonomous channel, subtracts
Small pressure at expulsion prevents external dust from entering the binary channels porous plug inside equipment.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of binary channels dust-proof air ventilation plug,
It is provided with step gas port wide at the top and narrow at the bottom, the step on top from top to bottom including threaded connector body, inside threaded connector body
It is provided with inlet flange seat in shape hole, is provided with exhaustion plate above inlet flange seat, is arranged between exhaustion plate and inlet flange seat
There are filter screen and filter cotton, inlet flange seat includes ring flange and cylinder, and multiple air inlets are arranged on ring flange, are arranged in cylinder
There is movable steel ball, cylinder lower opening is less than steel ball size, is provided with gland, gland and threaded connector body phase above exhaustion plate
Even.
The gland is to be threadedly coupled with the connection type of threaded connector body.
Air hole is evenly equipped on the gland.
The threaded connector body is that loose fit is connect with inlet flange seat, exhaustion plate.
The gland, exhaustion plate, filter screen, filter cotton, inlet flange seat, threaded connector body are coaxially arranged.
The filter screen and filter cotton are arranged between ring flange and exhaustion plate.
The utility model has the advantages that structure is simple compared with prior art, easy to use, air inlet and exhaust
For different channels, exhaust resistance is small, is internally provided with filter screen and filter cotton, and external dust can effectively be prevented to enter
Inside equipment, porous plug will not be blocked, use reliability is high.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure 1 be threaded connector body, 2 be inlet flange seat, 3 be exhaustion plate, 4 be filter screen, 5 be filter cotton, 6 be activity
Steel ball, 7 be gland, 21 be ring flange, 22 be cylinder.
Specific embodiment
As shown in Figure 1, a kind of binary channels dust-proof air ventilation plug of the utility model, including threaded connector body 1, threaded connector body 1
Inside is provided with step gas port wide at the top and narrow at the bottom from top to bottom, is provided with inlet flange seat 2 in the step-shaped hole on top, into
It is provided with exhaustion plate 3 above gas flange seat 2, filter screen 4 and filter cotton 5 are provided between exhaustion plate 3 and inlet flange seat 2, into
Gas flange seat 2 includes ring flange 21 and cylinder 22, and multiple air inlets are arranged on ring flange 21, movable steel ball is provided in cylinder 22
6,22 lower opening of cylinder is less than 6 diameter of steel ball, is provided with gland 7 above exhaustion plate 3, and gland 7 is connected with threaded connector body 1,
Gland 7 is to be threadedly coupled with the connection type of threaded connector body 1, and air hole, threaded connector body 1 and air inlet are evenly equipped on gland 7
Flange seat 2, exhaustion plate 3 are loose fit connection, and gland 7, exhaustion plate 3, filter screen 4, filter cotton 5, inlet flange seat 2, screw thread connect
Head body 1 is coaxially arranged, and filter screen 4 and filter cotton 5 are arranged between ring flange 21 and exhaustion plate 3.
When the utility model is used, movable steel ball blocks mouth under flange in lower section, and air passed through when air inlet
Equipment is entered by the air inlet in air inlet flange disks after strainer and filter cotton filtering, when exhaust, due to there is filter cotton,
Movable steel ball can only be pushed to be exhausted when exhaust, exhaust is discharged along exhaustion plate, can effectively prevent porous plug blocking, knot
Structure is simple, easy to use.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
