In the utility model, tank drainback interface tube have employed quick release coupling respectively with fuel filter fuel oil interface and is communicated with oil outlet tube with tank drainback pipe, this Placement has fixed advantage, achieve safe and efficient leak free rapid translating between pipeline, not only easy for installation, simultaneously convenient too when safeguarding dismounting.
As optimization, described fuel filter also comprises housing, the two ends of housing are respectively equipped with filler opening and oil outlet, netted filtering device for filter fuel impurity and Filter paper filtering device is provided with successively in described housing from filler opening to oil outlet, netted filtering device and Filter paper filtering device are detachable with housing to be respectively connected, and the filtration grade of described Filter paper filtering device is higher than the filtration grade of netted filtering device.Fuel oil enters in housing, first by netted filtering device, filters out the impurity that diameter is larger, then falls the less impurity of diameter through filter paper filtration devices, enters into oil-fired system below outside finally clean fuel oil outflow housing.Have employed the mode of classified filtering, different filtration grade filters the impurity of different-diameter respectively, enhances smoothing effect, improves working life, decreases the probability that filter cleaner is blocked by impurity.
As optimization, described housing comprises upper shell, central connector and lower shell body, and the two ends of described central connector are threaded with upper shell and lower shell body respectively.Have employed each several part be threaded, for convenience detach, be convenient to change the filtrating equipment in housing separately, reduce cost, reasonably make use of resource.
As optimization, described netted filtering device comprises the filtering cylinder and filter gauze that set gradually from filler opening to oil outlet, described Filter paper filtering device comprises filtering paper, the entrance point of described filtering cylinder is threaded with described filler opening, described filter gauze is connected with described housing is detachable, described filtering paper is connected with described housing is detachable, and the filtration grade of described filtering paper, filter gauze and filtering cylinder reduces gradually.Filtering cylinder is relative to filter gauze, and effective filtration area is larger, and can filter out the impurity particle that diameter is larger, then fuel oil filters successively through filter gauze and filtering paper again, further reduces the probability that filter cleaner is blocked by impurity, improves the working life of filter cleaner.
As optimization, the pore size filter of described filtering paper is 80 ~ 120 μm, and the order number of described filter gauze is 60 ~ 80 orders, and the order number of described filtering cylinder is 30 ~ 50 orders.
As optimization, the end face at described central connector two ends near the part of inner ring respectively along its formation collar flange that axially stretches out, between outside described collar flange and inside described upper shell and and described lower shell body inside between be respectively equipped with gap, described filter gauze and described filtering paper lay respectively at the collar flange place at described central connector two ends, are respectively equipped with the ring packing compressing member for described filter gauze and described filtering paper being fixed on collar flange in described gap.Filter gauze and filtering paper are fixed on the two ends of central connector respectively with ring packing compressing member, successively fuel oil is filtered, the compressing member of ring packing simultaneously seals further upper shell, central connector and lower shell body joint gap each other in gap, prevents fuel leakage out.
In sum, the beneficial effects of the utility model are: the utility model fuel oil filtering device structure is simple, it is more firm that quick release coupling makes tank drainback pipe be connected with the oil outlet tube of filter cleaner, simultaneously also more convenient in installation and removal, avoid and loosen and the fuel oil leakage that causes because Motor Vehicle vibrate the pipe joint brought; The mode that fuel filter have employed multistage filtering is in addition filtered the different impurities in fuel oil successively, and filtering effect is better, also reduces the probability that filter cleaner is blocked by impurity, ensures that fuel oil can flow into oil-fired system smoothly; Have employed the design of replaceable cartridge in addition, reduce cost, save resource.
