Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the Facad structure schematic diagram of a kind of aging-resistant engine intake of the present invention air throttle.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of aging-resistant engine intake air throttle of the present invention, comprise engine intake air throttle 1, intake manifold resonator cavity 2, multiple intake manifold arm 3 and joint flange 4, each intake manifold arm 3 upper end air throttle 1 is communicated with intake manifold resonator cavity 2, each air outlet, intake manifold arm 3 bottom is connected with each cylinder head respectively by joint flange 4, also comprise gas rail 5 and multiple gas rail connecting branch 6, gas rail connecting branch 6 and intake manifold arm 3 one_to_one corresponding, gas rail 5 is communicated with the lower end of each intake manifold arm 3 by gas rail connecting branch 6.
Described air throttle 1 is made up of ageing-resistant rubber, and this ageing-resistant rubber contains following component and weight part: viton 100 parts, 15 parts, barium sulfate, Calucium Silicate powder 20 parts, 6 parts, magnesium oxide, red iron oxide 6 parts, carbon black N7740.8 part, palm wax 0.8 part, WS2800.7 part, calcium hydroxide 0-1.5 part.
Viton (English name: Fluororubber) main Types has three kinds: fluorine carbon, fluorine silicon and fluoroalkyl phosphonitrile.Main production is fluorine carbon at present, and fluorine carbon viton mainly comprises: vinylidene and chlorotrifluoroethylene (23 glue); The multipolymer (26 glue) of vinylidene, R 1216; The terpolymer (246 glue) of vinylidene, R 1216 and tetrafluoroethylene; Tetrafluoroethylene and propylene (4 third viton).
In order to reach the ageing-resistant performance of air throttle of the present invention, present invention employs Du Pont's viton.
Preferably, described Du Pont's viton, the trade mark is VTR7576, can life-time service under 200 DEG C of environment; Can short-period used under 250 DEG C of environment.
Calcium hydroxide is a kind of white powdery solids, has another name called slaked lime.Calcium hydroxide has the general character of alkali, is a kind of highly basic.The alkalescence of calcium hydroxide is stronger than sodium hydroxide (movable metallic: calcium > sodium), but due to the solubleness of calcium hydroxide more much smaller than sodium hydroxide, so the corrodibility of aqua calcis and alkalescence less than sodium hydroxide.These character determine calcium hydroxide and are widely used.
Preferably, described calcium hydroxide adopts lime slaking method: by Wingdale after being sintered into calcium oxide, digest with the ratio of water in 1:3 through selected, generate calcium hydroxide feed liquid to remove the gred through purification separation, again through centrifuge dehydration, dry at 150 ~ 300 DEG C, then screen (more than 120 orders) and be calcium hydroxide finished product.Preferably, described calcium hydroxide belongs to industrial nano rank.
Intake manifold of the present invention, its air throttle is made up of ageing-resistant rubber, long service life, improves the reliability of integral intake manifold.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
