DETAILED DESCRIPTION
[0016] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0017] like Figure 1 , Figure 2 As shown, the detachable flange type oil filling port includes an oil filling cap 1, an oil filling cap sealing gasket 2, a flange oil filling port 3, an oil filling port sealing gasket 4, a port base 5, an oil filling joint 6, and an oil filling filter element 7. The port base 5 is welded on the oil tank body 17, the port base 5 is connected to the flange oil filling port 3, an oil filling port sealing gasket 4 is arranged between the flange oil filling port 3 and the port base 5, an oil filling interface 8 is arranged in the middle of the bottom of the flange oil filling port 3, the oil filling interface 8 is connected to the oil filling joint 6, the oil filling joint 6 is connected to the oil filling filter element 7, the oil filling cap 1 is connected above the flange oil filling port 3, and the oil filling cap sealing gasket 2 is placed between the flange oil filling port 3 and the oil filling cap 1.
[0018] A handle 9 is also provided above the oil filling cap 1, and the handle 9 is welded to the oil filling cap 1; the edges of the oil filling cap 1 and the oil filling cap gasket 2 are processed with a bolt mounting hole 10 and a bolt mounting hole 2 11 required for connection with the flange oil filling port 3; the upper surface of the flange oil filling port 3 is processed with a threaded hole 12 that cooperates with the bolt mounting hole 10 of the oil filling cap 1 and the bolt mounting hole 2 11 of the oil filling cap gasket 2, and a bolt 18 passes through the bolt mounting hole 10 and the bolt mounting hole 2 11 and cooperates with the threaded hole 12 to fix the oil filling cap 1, the oil filling cap gasket 2 and the flange oil filling port Port 3; a flange 13 is processed below the flange oil filling port 3, and bolt mounting holes 3 14 and bolt mounting holes 4 15 that cooperate with the port base 5 are processed on the flange 13 and the oil filling port sealing gasket 4; threaded holes 16 that cooperate with the bolt mounting holes 3 14 of the flange 13 and the bolt mounting holes 4 15 of the oil filling port sealing gasket 4 are processed on the upper surface of the port base 5, and bolts 19 pass through the bolt mounting holes 3 14 and the bolt mounting holes 4 15, and cooperate with the threaded holes 16 to fix the flange oil filling port 3, the oil filling port sealing gasket 4 and the port base 5.
