The purpose of this utility model is achieved in that a kind of secondary diesel-oil filter, comprise: transparent shell is spirally connected with being provided with into and out of the loam cake of oilhole, filter core is set in it, it is characterized in that: its filter core is upper and lower two-layer, the upper strata is that cotton core assembly and lower floor are that the paper filter element assembly separates by seal ring, the affixed center tube of the upper and lower difference of last core cap of its paper filter element assembly, center tube connection oil outlet and loam cake that its upper center tube penetrates the cotton core assembly are spirally connected, its lower center tube is that perforated tube and upper and lower core cap are affixed, and its transparent shell bottom is provided with blowdown valve.

Its loam cake oil outlet is provided with bleeder screw and scavenger valve; Its oil inlet hole is communicated with the shell chamber and is arranged at the cavity edge position.

Its cotton core assembly is clipped between core cap and the drain pan by cotton core, is six width of cloth wheel shapes, six hole wheel shapes at the bottom of core cap and the drain pan on it.

Its blowdown valve is closely cooperated by spool and transparent shell valve opening, and its spool and spring seat are solidified as a whole, and spring is arranged between the spring seat, and spring seat crouches down in the groove of core cap.

Between its transparent shell and the loam cake seal ring is set, its bleeder screw is provided with hollow via-hole, and its underpart is established the hole and is communicated with oil outlet and scavenger valve oil duct, and its bleeder screw top also is provided with through hole and is communicated with hollow hole.

The utility model its with upper and lower two-layer filter element filtering diesel oil, it is good that it has filtration properties, and sealing is tight, and can see the diesel oil that precipitates in this housing at any time by transparent shell, and can discharge water and dirt in the transparent bright body easily by blowdown valve, be covered with bleeder screw on it, can conveniently discharge gas in the oil, guarantee to start a glass machine normally to move, thereby engine horsepower is normally brought into play, reduce cost, prolong function and make the precision pair life-span.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Embodiment

Its structure of the utility model is as shown in Figure 1: a kind of secondary diesel-oil filter, comprise: transparent shell 1 be provided with into,

oil outlet

203,4 loam cake 2 is spirally connected, filter core is set in it, it is characterized in that: its filter core is last, two-layer down, the upper strata is that cotton core assembly 5 and lower floor are that paper filter element assembly 6 is by

seal ring

8,9 separate, on the last core cap 601 of its paper filter element assembly 6, under distinguish affixed center tube, the center tube 501 connection oil outlets 4 that its upper center tube 603 penetrates cotton core assembly 5 are spirally connected with loam cake 2, its lower center tube 604 is a perforated tube and last, following

core cap

601 and 602 is affixed, and its transparent shell 1 bottom is provided with blowdown valve 7.
