Abstract
The utility model discloses a breather valve, it adds and to be equipped with the closing cap, has offered the venthole on the closing cap and has installed additional in this closing cap and filtered, has eliminated noise pollution, and near the casing of having avoided leading to the fact because of the reason of giving vent to anger of breather valve has the problem of greasy dirt, has guaranteed under the prerequisite of ventilating for the backward flow of condensing in breather valve of most gear oil does not cause and pollutes and waste.
Description
Technical field
The utility model belongs to gearbox field, particularly a kind of vent valve.
Background technique
Transmission assembly in the course of the work, due to High Rotation Speed, can make transmission internal oil temperature rise, and simultaneously inner pressure also can increase thereupon.High-temperature high-pressure state can be unfavorable for the work of transmission assembly, and long term high temperature can make the reliability decrease of gear, oil sealing, bearing; Long-term high pressure can make the sealability of oil sealing decline, and occurs seepage, is also unfavorable for the formation of gear surface oil film simultaneously, also can causes the faults such as the spot corrosion of Gear Contact Surface, gummed.
Produce High Temperature High Pressure in order to avoid transmission assembly is inner in the course of the work, current transmission assembly all can install vent valve additional, is arranged on the correct position of gear box casing, ensures that the pressure in transmission assembly working procedure can not exceed scope allowable.
Existing vent valve as shown in Figure 1, it comprises bonnet 101 and valve body 102, valve body 102 is arranged on gear box casing by the tapered thread of lower end, and the gas of transmission assembly inside is by the passage of valve inner, be discharged to outside through valve body 102 and the gap of bonnet 101.The pressure be vented can be controlled by regulating valve bonnet 101 and the gap of valve body 102.There is following defect in this vent valve:
One, when oil gas is at high temperature under high pressure from above-mentioned vent valve ejection, meets cool ambient air and condense rapidly, easily form greasy dirt, pollute bonnet 101 and valve body 102.
Two, the bleed passage of vent valve is too straight, is unfavorable for that gear oil cooled and solidified in vent valve of evaporating is back in casing.
Three, pressurized gas easily produce noise when valve body 102 is discharged.
Model utility content
Technical problem to be solved in the utility model be to provide a kind of avoid greasy dirt formed, guarantee most of gear oil can cooling for reflux, noise free produce vent valve.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of vent valve, comprise bonnet and valve body, described bonnet is sleeved on the upper end portion of described valve body, and capping is also sleeved on the upper end portion of this valve body and is placed in described bonnet, radial direction through hole in described valve body is placed in described capping, this capping offers multiple air outlet hole and inside is equipped with filter member.
Preferably, described filter member is the filter screen be made up of metal or synthetic fiber.
Preferably, described filter member is the space wadding being filled in described capping inside.
Preferably, described air outlet hole is positioned at the upper end-face edge place of described capping.
Preferably, gap is provided with between described air outlet hole and described bonnet inwall.
Preferably, between described bonnet and described capping be interference fit.
Preferably, on the inwall of described bonnet, on the inwall of described capping and described valve outer wall scribbles resin layer.
A kind of vent valve provided by the utility model, it adds capping, capping offers air outlet hole and install filter member additional in this capping, eliminate noise pollution, avoid housing near the vent valve that causes because of reason of giving vent to anger and have the problem of greasy dirt, ensure that under the prerequisite of ventilation, most gear oil is condensed backflow in vent valve, does not pollute and waste.

The axonometric drawing of capping in the vent valve that Fig. 5 provides for the utility model embodiment.
In Fig. 1, reference character is: 101 bonnets, 102 valve bodies.
In Fig. 2 to Fig. 5, reference character is: 1 bonnet, 2 valve bodies, 3 cappings, 4 radial direction through hole, 5 air outlet holes, 6 filter member, 7 pipelines.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figures 2 to 5, a kind of vent valve comprises bonnet 1 and valve body 2, bonnet 1 is sleeved on the upper end portion of valve body 2, capping 3 is also sleeved on the upper end portion of this valve body 2 and is placed in bonnet 1, radial direction through hole 4 in valve body 2 is placed in capping 3, this capping 3 offers multiple air outlet hole 5 and inside is equipped with filter member 6, this filter member is the filter screen be made up of metal or synthetic fiber.In order to obtain better oil absorption and abate the noise better, filter member 6 also can select the space wadding being filled in capping 3 inside.
A kind of embodiment, as shown in Figure 3 and Figure 5, air outlet hole 5 is six, is evenly distributed on the upper end-face edge place of capping 3, so that the processing of this air outlet hole 5.In order to make oil gas to flow out vent valve more smoothly and not make a noise, so, preferably, between air outlet hole 5 and bonnet 1 inwall, be provided with gap.Be interference fit between bonnet 1 and capping 3, thus guarantee the sealing between both.
In order to prevent oil gas from causing corrosion to vent valve, reduce the working life of this vent valve, so on the inwall of bonnet 1, on the inwall of capping 3 and valve body 2 outer wall scribbles resin layer.
High-temperature oil gas in transmission assembly enters in filter member 6 by the pipeline 7 in valve body 2 heart portion, and cool fully in filter member and drying, the gas after filtration is discharged in air by the air outlet hole 5 at capping 3 place and goes.
Gear oil under filtration can be back in transmission assembly by the pipeline 7 in valve body 2 heart portion by the structural design of filter member 6 and capping 3 again, the gear oil avoiding evaporation is discharged to outside gearbox with high-temperature gas, causes the greasy dirt of vent valve transmission housing surface.The discharge of high-temperature oil gas have passed through valve body 2, filter member 6, air outlet hole 5 and bonnet 1, obtains and filters fully and cooling, ensure that drying and the low temperature of Exhaust Gas, and can not cause noise pollution.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other mode of execution easily according to guiding theory of the present utility model, and these mode of executions are all included within scope of the present utility model.
