Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 2, an ash discharging ball valve comprises a valve body 1, an upper valve rod 2, a lower valve rod 3, a packing pressure plate 4, a bottom cover 5 connected to the valve body, a valve cover 6 and a ball body 7 arranged in the valve body, wherein the upper end and the lower end of the valve body 1 are respectively provided with an upper bearing and a lower bearing, the lower valve rod 3 is sleeved in the lower bearing fixed at the lower end of the valve body 1, the upper valve rod 2 is sleeved in the upper bearing fixed at the upper end of the valve body 1, the packing pressure plate 4 is arranged between the upper valve rod 2 and the valve body 1, a driving device 15 is further arranged above the valve body 1, one end of the upper valve rod 2 extending out of the valve body 1 is sequentially connected with a gland 8 and a ratchet 9 from top to bottom in a key manner, the ratchet 9 is arranged in the gland 8, the ratchet 9 is of a four-tooth structure, the included angle between two adjacent, a pawl pin shaft 11 and an air cylinder pin shaft 12 are fixedly arranged between the connecting rods 10, a pawl 13 meshed with the ratchet wheel is further connected to the pawl pin shaft 11 in a key mode, a cylinder rod of the driving device 15 is rotatably connected with the air cylinder pin shaft 12, a signal support 14 is further arranged at one end, extending out of the bottom cover 5, of the lower valve rod 3, a four-grab switch signal device is arranged in the signal support 14, and a proximity switch is arranged on one side of the four-grab switch signal device.
