Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides an automatic water drain valve for hydrogen energy fuel cell exhaust, including an upper valve body 1 and a lower valve body 2.

Referring to fig. 1, 2 and 3, the upper valve body 1 is a T-shaped pipe body, two ends of the upper valve body 1, which are horizontally arranged, are respectively provided with a water inlet 3 and a water outlet 4, the water inlet 3 and the water outlet 4 are both tubular joints, the water inlet 3 and the water outlet 4 are both provided with external threads, the water inlet 3 and the water outlet 4 can be connected to a hydrogen energy fuel cell exhaust pipe in a threaded manner, and a vertical end of the upper valve body 1 extends downward.

Referring to fig. 1, 2 and 3, the lower valve body 2 is a tapered tube body with a thick upper end and a thin lower end, the lower valve body 2 is disposed below the upper valve body 1, and an upper port of the lower valve body 2 is connected to a vertical end of the upper valve body 1, and may be screwed or welded. The lower end opening of the lower valve body 2 is a water outlet 5, and the water outlet 5 is a circular opening which is horizontally arranged. The lower valve body 2 is internally provided with a floating ball 6, a ball discharging handle 7 and a plurality of limiting columns 8, the radius of the floating ball 6 is slightly larger than the caliber of the water discharging opening 5, the lower part of the ball discharging handle 7 is provided with a disc 9 which is horizontally arranged, all the limiting columns 8 surround the water discharging opening 5, the upper ends of all the limiting columns 8 are fixedly connected with the bottom surface of the disc 9, the lower ends of all the limiting columns 8 are fixed on the inner wall of the lower valve body 2, the floating ball 6 is arranged above the water discharging opening 5 and blocks the water discharging opening 5 and is constrained among the limiting columns 8, so that the floating ball 6 can move between the water discharging opening 5 and the disc 9.

In this embodiment, the number of the limiting columns 8 is three, and the three limiting columns 8 are arranged in a regular triangle to surround the floating ball 6, so as to prevent the floating ball 6 from jumping during the running of the vehicle, thereby causing a large amount of hydrogen to escape.
