Abstract
The invention discloses a stainless steel oil filling port comprising a flange welded on an oil filling port of an oil tank, wherein the flange is provided with a short cylinder; the periphery of the lower end of the short cylinder is fixedly arranged on the flange; a radial inner convex edge is arranged in the circumferential direction of the upper end of the short cylinder; and a copper sintered filter element is arranged in the short cylinder. A cover is arranged outside the short cylinder, a spacing is retained between the top of the cover and the upper end of the short cylinder, the other spacing is retained between the periphery of the cover and the periphery of the short cylinder, and each spacing communicates with the outside air. The stainless steel oil filling port is characterized in that the inner side wall of the short cylinder is provided with a screw thread, a pressing ring is arranged in the short cylinder, the outer circumferential side of the pressing ring is provided with a screw thread, and the copper sintered filter element can be tightly pressed on the lower surface of the radial inner convex edge through screwing up the pressing ring. By using the stainless steel oil filling port, the copper sintered filter element can be prevented from being damaged, so that the production cost is reduced; and the stainless steel oil filling port is suitable for an oil tank for an industrial hydraulic system.
Description
Technical field
The present invention relates to a kind of tank filler.Specifically, it is the rustless steel oil filler of industrial hydraulic system oil case.
Background technology
At present, at the oil filler of industrial hydraulic system oil case, it is equipped with greatly the copper sintering for filtering and breathe air
Filter element, in order to when fluid stereomutation in fuel tank, makes the pressure inside and outside fuel tank keep consistent by air breathing mouth.Tradition
Rustless steel oil filler, including being welded on the flange of oil filler, flange has short cylinder, short cylinder lower end surrounding are fixed on flange,
The circumference of short cylinder upper end has radially inner raised edge, has copper sintered filter core, copper sintered filter core center to have nail in short cylinder；Have outside short cylinder
Cover cap, all has spacing between hood top and short cylinder upper end and between cover cap surrounding and short cylinder surrounding, described spacing is with outside air even
Logical.Wherein, the medial surface center weld of cover cap has nut, during installation, uses screw and makes screw upper end through copper sintered filter core
Screw in after the nail at center in the nut inside cover cap, so that the surrounding of copper sintered filter core is closely attached to the radial direction of short cylinder upper end
Inside inner raised edge.Owing to using screw to be closely attached to inside the radial direction inner raised edge of short cylinder upper end by the surrounding of copper sintered filter core, one
Denier overexerts or the most uneven, all easily causes the damage of copper sintered filter core.Again owing to using screws to fixed copper sintering filter
Core, needs to process nail at copper sintered filter core center.And it is pressed together formation after the heating of copper sintered filter core shot copper,
Processing nail on copper sintered filter core relatively difficult, in production process, percent defective is higher, and production cost is higher.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of rustless steel oil filler.Use this rustless steel oil filler, can avoid
The damage of copper sintered filter core, reduces production cost.
The problems referred to above that the invention solves the problems that are realized by techniques below scheme:
The rustless steel oil filler of the present invention includes the flange being welded on tank filler, and flange has short cylinder, short cylinder lower end surrounding
Being fixed on flange, the circumference of short cylinder upper end has radially inner raised edge, has copper sintered filter core in short cylinder.Cover cap is had, cover outside short cylinder
Spacing, described spacing is all had to connect with outside air between tops and short cylinder upper end and between cover cap surrounding and short cylinder surrounding.It is special
There is screw thread on the inner side barrel of the described short cylinder of point, have trim ring in short cylinder, trim ring cylindrical has screw thread, can be by by screwing this trim ring
Copper sintered filter core is pressed at the lower surface of radially inner raised edge.
Further improvement of the present invention scheme is, there is circumferential outer flange short cylinder lower end, and short cylinder lower end is by circumference outer flange
It is fixed on described flange with screw；It is evenly equipped with passage on the circumference of described circumference outer flange.
As can be seen from the above scheme, owing to having screw thread on the inner side barrel of described short cylinder, there is trim ring in short cylinder, outside trim ring
There is screw thread on circle, copper sintered filter core can be pressed on by screwing this trim ring at the lower surface of radially inner raised edge.With background technology
Compare, be not required on copper sintered filter core process nail, thus the percent defective in production process and production cost can be substantially reduced.Again
Owing to using trim ring can be pressed on by copper sintered filter core at the lower surface of radially inner raised edge, the stress point of copper sintered filter core is distributed on
Its surrounding, compared with the stress point of the copper sintered filter core heart wherein in background technology, the uniform force of copper sintered filter core during installation,
Copper sintered filter core is hardly damaged.
Accompanying drawing explanation
Fig. 1 is the rustless steel oil filler structure schematic diagram of the present invention.
Detailed description of the invention
As it is shown in figure 1, the rustless steel oil filler of the present invention includes the flange 9 being welded on fuel tank 10 oil filler, set in flange 9
It is equipped with gauze filter 11.Be provided with short cylinder 8 on flange 9, short cylinder 8 lower end be machined with circumference outer flange 2, short cylinder 8 lower end by
Circumference outer flange 2 and screw are fixed on described flange 9；It is evenly equipped with passage 1 on the circumference of described circumference outer flange 2.Short cylinder 8
The circumference of upper end is machined with radially inner raised edge 4, is provided with copper sintered filter core 5 in short cylinder 8.Cover cap 6 it is provided with, cover outside short cylinder 8
Covering between 6 tops and short cylinder 8 upper end and all leave spacing 3 between cover cap 6 surrounding and short cylinder 8 surrounding, described spacing 3 is by passage 1
Connect with outside air.It is threaded on the inner side barrel of described short cylinder 8, is provided with trim ring 7 in short cylinder 8, on trim ring 7 cylindrical
It is threaded, by screwing the lower surface that copper sintered filter core 5 can be pressed on the radial direction inner raised edge 4 of short cylinder 8 upper end by trim ring 7
Place so that the stress of copper sintered filter core 5 is highly uniform, thus avoids the damage that copper sintered filter core 5 causes because of discontinuity
Bad, substantially prolongs the service life of copper sintered filter core 5.
