Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

Referring now to fig. 1-6, a blowoff valve 200 for a transmission 20 according to an embodiment of the present invention is described, including: a valve housing 220, a soil drainage pipe 230, and a baffle 240.

Specifically, the soil discharge pipe 230 is bent and disposed in the valve housing 220; and a baffle 240 is disposed in the valve housing 220, the baffle 240 is positioned at the outlet of the soil discharge pipe 230, and a soil through opening 250 is formed between the baffle 240 and the valve housing 220.

It can be understood that, by providing the soil exhaust pipe 230 and the baffle 240 on the soil exhaust valve 200, the soil exhaust pipe 230 is adapted to guide moisture, so that the moisture entering the transmission 20 can be exhausted out of the transmission 20 through the soil exhaust pipe 230, thereby avoiding the influence of the moisture on the operation process of the transmission 20, and improving the service performance of the transmission 20, and meanwhile, because the moisture is adapted to be exhausted out of the transmission 20 more quickly, the staying time in the transmission 20 is shorter, and the structural corrosion degree of the transmission 20 caused by the moisture can be reduced, so that the use of the transmission 20 is more reliable.

And in blowoff valve 200, not only be equipped with blow off pipe 230 in valve casing 220 in order to lead the discharge to moisture, still be equipped with baffle 240 in valve casing 220, because be equipped with logical dirty mouth 250 between baffle 240 and the valve casing 220, logical dirty mouth 250 is suitable for the moisture that leads the blow off pipe 230 and leads the circulation, so that moisture can be faster discharges in blowoff valve 200, in order to avoid moisture to gather in valve casing 220 in order to influence the use of derailleur 20, thereby let the use reliability of derailleur 20 obtain promoting, in order to promote the performance of derailleur 20.

According to the utility model discloses blowoff valve 200 of derailleur 20 through be equipped with blow off pipe 230 and baffle 240 in blowoff valve 200, blow off pipe 230 can derive the moisture in the derailleur 20 from the derailleur 20 to avoid moisture to the influence of derailleur 20 in the use, let derailleur 20's use more safe and reliable, in order to promote derailleur 20's life. Meanwhile, the baffle 240 arranged in the blowoff valve 200 guides the moisture entering the blowoff valve 200, so that the moisture can be discharged out of the transmission 20 through the blowoff valve 200 more quickly, and the service performance of the transmission 20 is improved.

In some embodiments, as shown in fig. 2 and 3, the drainage pipe 230 is curved or curved, and it should be noted that the drainage pipe 230 may be J-shaped, so as to prevent outside splash from entering the transmission 20, and allow the moisture entering the drainage pipe to slide down and be discharged to the outside environment due to its own weight. Thus, the drain 230 is constructed in an arc shape or a curved shape, so that moisture can be discharged from the transmission 20 along the drain 230 more rapidly when the drain 230 guides the moisture, thereby making the transmission 20 more reliable to use.

In some embodiments, as shown in figures 2 and 3, the cross-sectional area of the waste pipe 230 decreases in the direction of waste. Thus, the cross-sectional area of the sewage draining pipe 230 decreases in the sewage draining direction, so that when the moisture flows through the sewage draining pipe 230 in a guiding manner, the moisture can flow through the sewage draining pipe 230 at a higher speed, and the moisture can be discharged from the transmission 20 more quickly, so that the service performance of the transmission 20 is improved.

In some embodiments, the baffle 240 is disposed obliquely within the valve housing 220. Thus, since the baffle 240 is obliquely disposed within the valve housing 220, the moisture is adapted to be guided to flow by the obliquely disposed baffle 40 to be discharged from the soil-discharge opening 250 disposed between the baffle 240 and the valve housing 220 when the moisture is transferred and guided to the baffle 240, thereby allowing the drainage performance of the soil-discharge valve 200 to be improved.

In some embodiments, as shown in fig. 2 and 3, there are at least two baffles 240, at least two baffles 240 are disposed at an angle in the valve housing 220, and the drain openings 250 of two adjacent baffles 240 correspond to opposite sides of the valve housing 220. Thus, the baffle 240 is disposed obliquely, on one hand, the baffle 240 is suitable for providing guiding circulation for moisture discharge in the transmission case 10, so as to improve moisture discharge efficiency, thereby improving service performance of the transmission 20, and on the other hand, the baffle 240 is also suitable for blocking external moisture from entering, so as to ensure more reliable use of the transmission 20. Meanwhile, since the soil-through openings 250 of two adjacent baffles 240 are adapted to be constructed at the same side of the valve housing 220, the soil-through openings 250 can better discharge moisture, etc., to improve the usability of the soil exhaust valve 200.

In some specific embodiments, the baffle 240 is welded within the valve housing 220; or the shutter 240 is installed in the valve housing 220 by a hinge. It will be appreciated that the baffle 240 is welded to the valve housing 220 to provide a more secure construction of the baffle 240 within the valve housing 220, thereby providing a more secure drainage of water from the transmission housing 10 by the blowoff valve 200 and a more secure use of the blowoff valve 200. The hinge mounting method can adjust the inclination angle of the baffle 240 in the valve housing 220. If there is more moisture in the transmission case 10, it is desirable to raise the angle of the baffle 240 to increase the rate of drainage, and to lower the angle of the baffle 240 to prevent moisture from entering the indoor environment from the outside when water splashes around.

In some embodiments, as shown in fig. 2, the valve housing 220 has an inlet 221 and an outlet 222, the inlet 221 having a cross-sectional area greater than the outlet 222. Thus, because the cross-sectional area of the inlet 221 is larger than that of the outlet 222, when moisture is accumulated in the transmission case 10, the moisture can quickly flow into the blowoff valve 200 and be discharged under the guidance of the blowoff valve 200, so that the influence on the transmission 20 when the moisture is accumulated in the transmission 20 is reduced, and the service performance of the transmission 20 is improved.

It will be appreciated that a receiving cavity 101 is provided in the transmission 20, and a waste outlet 110 provided in the receiving cavity 101 is adapted to provide an assembled position for the waste valve 200, thereby making construction of the waste valve 200 on the transmission 20 simpler and more reliable. The blowoff valve 200 is in a normally open state in the direction from the accommodating cavity 101 to the external space, so that all things which influence the work, such as moisture and impurities possibly accumulated in the transmission 20 in the using process, are suitable for being discharged through the blowoff valve 200, thereby avoiding the influence of moisture on the transmission body 11 and improving the using performance of the transmission 20.

In some embodiments, as shown in fig. 1, 2, 3, and 4, the outer periphery of the waste valve 200 is provided with a stepped surface 210.
