A kind of universal generator fuel tank cap, the sidewall comprising circular roof and extend straight down along this roof outer, described side wall lower ends is internal thread segment, and upper end is smooth section, described smooth section is provided with at least 2 pieces of oily reeds of gear, and be uniformly distributed on the same level cross section of sidewall, to form sealing configuration, every block keeps off oily reed lower end surface and arranges stage clip respectively, and described stage clip upper end is fixed on the center of the oily reed of corresponding gear, lower end is outward-dipping, and is fixedly supported in the smooth section of sidewall;
Described roof is equipped with oil filler pipe slidably, and described oil filler pipe passes vertically through the center of roof, and the length of this oil filler pipe is greater than the distance between gear oily reed to roof.
Adopt above structure, coordinated with the oily reed of gear by oil filler pipe, achieve the function not needing loosening fuel tank cap to get final product fuel up, while easy-to-operat, also improve the sealability of fuel tank cap.
Preferably, the oily reed of described gear is 3 pieces altogether, the flexible rubber of its surfaces be clad.This structure is when keeping off oily reed and closing, and the elastic caoutchouc at gap place can fit tightly betwixt, further increases the sealability of fuel tank cap.
Preferably, described oil filler pipe is installed with upper stop piece and lower stop piece, described upper stop piece is positioned at oil filler pipe and stretches out upper end outside roof, and described lower stop piece is at roof and keep off between oily reed, and and leave distance between oil filler pipe lower end, the lower end surface of this lower stop piece is provided with sealing gasket.Adopt above structure, can carry out spacing to the upper and lower stroke of oil filler pipe easily, prevent its transition from stretching into or deviating from from fuel tank cap, the sealing gasket on lower stop piece can guarantee that oil filler pipe lower end is after backing down the oily reed of gear, to the effective sealing of its end face.
Preferably, described oil filler pipe and roof cooperation position are provided with stuffing box gland, to ensure the reliable sealing between roof and oil filler pipe.
Preferably, one end that described oil filler pipe stretches out roof at it is provided with pipe cap, and this pipe cap is being provided with vent.This structure can improve the sealability of fuel tank cap, prevents fuel oil from leaking from oil filler pipe, and the setting of vent is to balance external and internal pressure, occurs negative pressure in the chamber between anti-backstop oil reed and roof.
Beneficial effect: the universal generator fuel tank cap adopting above technological scheme, structure is simple, novel, and sealing is reliable, achieves the function not needing loosening fuel tank cap to get final product fuel up, while easy-to-operat, also improves the sealability of fuel tank cap.
