Abstract
The invention discloses a kind of filter element, including upper end cover, bottom end cover and refill, described refill is arranged between upper end cover and bottom end cover and refill is sleeved on the outer wall of central canal, being wound with glass line on the lateral wall of described refill, described glass line is bonded on the lateral wall of refill by thermosol. Glass line is wrapped in refill surface by coil winding machine, technique is simple, easy to make, it is easily controlled, and product appearance is attractive in appearance, glass line is thinner, the cushion rubber of more than 10mm is reached compared to width in prior art, actual filtration area without influence on filter paper, and then improve filter efficiency and the filter quality of filter element, glass line and thermosol have the resistant to elevated temperatures characteristic of resistance to machine oil, and filter element invades bubble for a long time in the machine oil that temperature is higher, glass line and thermosol did not both come off, and polluted machine oil without being dissolved in machine oil.
Description
Technical field
The present invention relates to a kind of filter element.
Background technology
Traditional filter cartridge construction is mostly: valve seat is as a whole with end cap, central canal is a hollow cylinder, its advantage is that injection mold structure is fairly simple, and production of plastics parts is relatively easy, but the major drawbacks of this structure is: in filter element and filter paper connection procedure, end cap needs heated baking, owing to the boss of valve seat is positioned at the side that end cap is connected with filter paper, when heated baking, valve seat is easily deformed, thus affecting the assembling of spool and valve seat, and then affect the filter effect of filter element.
Summary of the invention
Problem to be solved by this invention is to provide a kind of filter element, it is to avoid end cap valve seat in heating process is deformed because toasting, it is ensured that the assembling quality of valve seat and spool, thus ensureing the filter effect of filter element.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of filter element, including upper end cover, bottom end cover and refill, described refill is arranged between upper end cover and bottom end cover, being wound with glass line on the lateral wall of described refill, described glass line is bonded on the lateral wall of refill by hot-setting adhesive. Glass line is wrapped in refill surface by coil winding machine, technique is simple, easy to make, it is easily controlled, and product appearance is attractive in appearance, glass line is thinner, the cushion rubber of more than 10mm is reached compared to width in prior art, actual filtration area without influence on filter paper, and then improve filter efficiency and the filter quality of filter element, glass line and hot-setting adhesive have the resistant to elevated temperatures characteristic of resistance to machine oil, and filter element long period of soaking is in the machine oil that temperature is higher, glass line and hot-setting adhesive did not both come off, and polluted machine oil without being dissolved in machine oil.
Improve, described upper end cover is provided with the first through hole, described first through hole is provided with valve seat, the medial wall of described upper end cover is provided with the card convex radially-inwardly stretched out, the lateral wall of described valve seat is provided with and the draw-in groove of card convex snap-fit engagement, the upper surface of described card convex and the medial wall of card convex, by chamfered transition, described valve seat are positioned at the external diameter internal diameter less than card convex of the lower surface that the lateral wall below draw-in groove is inclined-plane and valve seat.After valve seat is placed in through hole, first to valve seat applied thrust, valve seat is under the effect of thrust, valve seat is positioned at and below draw-in groove, partially passes through through hole that card convex surrounds until card convex and draw-in groove clamping, the setting of valve seat ramp makes to be positioned on valve body and partially passes through, below draw-in groove, the through hole that card convex surrounds, valve seat is attached on upper end cover after upper end cover and refill connect again, avoid the heating process of upper end cover, valve seat will not deform, ensure that the assembling quality with spool, thus ensure that the filter effect of filter element.
Improving, the diapire of described draw-in groove is provided with the projection extended radially out, and the medial wall of described projection and card convex fits. The medial wall of card convex is prone to fully fit with projection and guarantees the assembling quality of valve seat and upper end cover.
Improving, described valve seat is provided with the second through hole for positioning spool.
Improving, described glass line is spirally wrapped around on the lateral wall of refill. Being evenly distributed, effect is optimum.
Beneficial effect:
After adopting technique scheme, this invention one filter element, glass line is wrapped in refill surface by coil winding machine, technique is simple, easy to make, it is easily controlled, and product appearance is attractive in appearance, glass line is thinner, the cushion rubber of more than 10mm is reached compared to width in prior art, actual filtration area without influence on filter paper, and then improve filter efficiency and the filter quality of filter element, glass line and hot-setting adhesive have the resistant to elevated temperatures characteristic of resistance to machine oil, filter element long period of soaking is in the machine oil that temperature is higher, glass line and hot-setting adhesive did not both come off, machine oil is polluted without being dissolved in machine oil.
Accompanying drawing explanation
