Abstract
The present invention relates to a diesel oil filter for a double core transparent cup, which comprises main components, such as an upper cover, a transparent cup, an outer filtering core, an inner filtering core, an exhaust valve, a spring lower seat, etc. The present invention uses two semi-closed filtering cores to filter diesel oil. A filtering cup is visual and transparent, and can find and discharge dirt (or water) which mixes in the diesel oil in time, and an exhaust valve rod is pressed to realize gas discharging without disassembly. The spring lower seat is pressed to complete the functions of dirt discharging and flushing without disassembly. All oil used for flushing can be recovered and combusted after precipitation is removed.
Description
Technical field
The present invention relates to a kind of dual-core filter with transparent cup for diesel oil, belong to diesel oil filtering equipment.
Background technique
As everyone knows, existing diesel-oil filter is made up of loam cake, filter bowl and filter core usually, inside and outside poorly sealed phenomenon appears after unpicking and washing easily, thereby do not guarantee filtering efficiency, in the process of unpicking and washing, also can waste a large amount of fuel oils, owing to can not in time find and discharge water and dirt in the diesel oil, so often cause the damage of precise parts such as oil nozzle, plunger.Both influence normal operation, also increased fuel consume.Also have when the air in the diesel oil can not in time be discharged, also make the diesel engine cisco unity malfunction.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of dual-core filter with transparent cup for diesel oil is provided, its objective is when guaranteeing filtering efficiency, can in time find and exempt to tear open the water, dirt and the air that deposit in the eliminating transparent cup.
The object of the present invention is achieved like this, a kind of dual-core filter with transparent cup for diesel oil is provided, it comprises loam cake, spring, seal ring etc., transparent cup and inner filter core spin with screw thread and loam cake, between outer filter core transparent cup and loam cake seal ring is housed, the pressure of outer filter core compressing seal ring is from spring below the spring seat of honour, inner filter core, outer filter core are sleeved in the transparent cup and use, it is characterized in that transparent cup makes with transparent material, the bottom of transparent cup is provided with pollutant exhaust hole, and this pollutant exhaust hole utilizes the pressure of spring to finish sealing by spring lower seat and sealing gasket.Its feature is equipped with outlet valve or bleeder screw at loam cake in addition, and outlet valve is made up of bleeder screw, exhasut valve stem, spring and rubber cushion.When finding that the filter cleaner inner chamber stockpiles air, push exhasut valve stem, or unscrew bleeder screw, just air can be discharged.
Owing to adopted such scheme, it has the filtering efficiency height dual-core filter with transparent cup for diesel oil, inside and outside good seal performance; Can in time find and can be in order to avoid tear discharge open, water that deposits in the transparent cup and dirt and air, flushing oil is recyclable through the filtering post precipitation.
Description of drawings
Fig. 1 is the longitudinal section of the embodiment of the invention 1;
Fig. 2 is the partial sectional view of the embodiment of the invention 2.
In the drawings, 1 loam cake, 2 transparent cups, 3 outer filter cores, 4 inner filter cores, the 5 spring seats of honour, 6 springs, 7 spring lower seats, 8 seal rings, 9 sealing gaskets, 10 oil return assembling bolts, 11 bleeder screws, 12 oil inlet holes, 13 oil outlets, 14 fixed bolt holes, 15 exhasut valve stems, 16 rubber cushions, 17 springs.
Embodiment
The present invention is further described below in conjunction with embodiment.
Referring to accompanying drawing 1 dual-core filter with transparent cup for diesel oil by loam cake 1, transparent cup 2, outer filter core 3, inner filter core 4, the spring seat of honour 5, spring 6, spring lower seat 7 is formed, transparent cup 2 screws with loam cake 1 with inner filter core 4 and engages, outer filter core 3, between transparent cup 2 and the loam cake 1 seal ring 8 is housed, guaranteed diesel oil at first through outside after filter core 3 filters, filter through inner filter core 4 again, the seal ring 8 that transparent cup 2 and loam cake are 1 can guarantee that diesel oil does not leak outside, outer filter core 3 and inner filter core 4 are sleeved in the transparent cup 2 and use, 5 pocketed springs, 6 backs, the spring seat of honour externally filter core 3 produce pressure, through seal ring 8 and loam cake 1 sealing, spring lower seat 7 one ends are made grow cylindric, pass the pollutant exhaust hole of sediment bowl 2 behind the suit sealing gasket 9, finish sealing with the elastic force of spring 6.When pushing the spring lower seat 7 that exposes transparent cup 2, can realize exempting to tear open blowdown.The oil return assembling bolt 10 of loam cake 1 can reclaim Fuel Remained, when having air in the oil return, air just can be filled the top of filter cleaner inner chamber, make in the oil outlet 13 and be full of air, when pushing exhasut valve stem 15 with hand, pressure spring 17 moves down rubber cushion 16, and air is promptly discharged or the bleeder screw 11 of outwarding winding from the hole of bleeder screw 11, exhausting air.Fixed bolt hole 14 is the bolts hole that filter cleaner are fixed on the relevant position.
Referring to accompanying drawing 2, after diesel oil enters filter cleaner from oil inlet hole 12, at first flow into the space of transparent cup 2 and outer filter core 3, through outside after filter core 3 filters, most impurity is blocked in the outside of outer filter core 3, again after inner filter core 4 filtrations, the diesel oil of cleaning flows into oil outlet 13, supplies with oil pump through oil outlet 13.
