Detailed Description
Referring to the attached drawings, the utility model provides a disassembly tool of a combined fuel valve, which comprises a bracket 1, a T-shaped rod 2, a base 3, a shell 4 and a valve core 5; the support 1 is of a 'nearly' shape structure, two ends of the support are respectively provided with a threaded hole, 2 threaded holes of the support 1 are respectively matched with threaded rods of 2T-shaped rods 2, and the upper surface of the support 1 is matched with the inner side of a handle of the valve core 5; the T-shaped rod 2 consists of a threaded rod and a rectangular rod perpendicular to the threaded rod, and the bottom of the threaded rod of the T-shaped rod 2 is propped in an upper counter bore of the base 3; the base 3 is a rectangular plate with a counter bore, and the bottom surface of the base 3 is positioned on the upper surface of the supporting plate 6 of the shell 4; the shell 4 is a cylindrical member, and an annular supporting plate 6 is arranged on the outer circumference of the upper end of the shell 4 and used for installing the base 3; the inner wall of the shell 4 is matched with the outer circle of the valve core 5; the valve core 5 is a valve core of a fuel valve, and the top of the valve core is provided with a handle. In practical applications, the housing 4 is a fuel valve housing or a fuel tank wall plate.
The upper surface of the bracket 1 is matched with the inner side of a handle of the valve core 5 and is used for driving the handle to pull out the valve core.
The surface of the rectangular rod of the T-shaped rod 2 is provided with knurling, and the main purpose is to improve the grasping friction of hands and prevent loosening in the screwing process.
The base 3 is used for bearing resistance in the process of removing the valve core.
The upper end of the base 3 is provided with a counter bore which is matched with the end part of the threaded rod of the T-shaped rod 2 and used for positioning the base 3 and preventing the base 3 from sliding in the working process.
The base 3 is tightly attached to the supporting plate 6 or is tightly pressed on the supporting plate 6 through a rubber pad.
