Abstract
The utility model provides a fuel filter with oil pressure adjusting device, including casing, regulator body etc. Its characterized in that: still include meticulous filter screen, annular magnet, fire -retardant layer, oil pressure adjusting device, the oil inlet has been seted up to the one end of casing, and the oil -out has been seted up to the other end, be provided with fire -retardant layer on the inner wall of casing, install the filter core in the casing. The utility model discloses be provided with annular magnet, but the engine is avoided haring by the metal fillings impurity in the effective absorption fluid, is provided with oil pressure adjusting device in the casing, avoid that the oil pressure undersize leads to that the fuel feeding is slow, the too big engine that leads to of oil pressure damages and need not additionally to add the oil pressure regulator, practice thrift occupation space, manufacturing cost, be provided with O type circle for assemble more inseparable, stability, avoid fluid to reveal and cause the extravagant and initiation potential safety hazard of the energy, be provided with fire -retardant layer, avoid the potential safety hazard because of rising of fluid flow temperature or external environment's influence initiation.
Description
Technical field
The utility model relates to a kind of filter cleaner, particularly relates to a kind of fuel filter with hydraulic adjustment device.
Background technique
At present, vehicular engine is all internal-combustion engine substantially, main use gasoline and diesel oil two kinds of fuel.As fuel, just must there is certain requirement to the quality of oil plant and clean degree, due to refining processing aspect, containing impurity such as certain moisture, colloid and metal fillingss in fuel oil.The effect of fuel filter is exactly by the impurity filtering in fuel oil, to the fuel oil of motor supplying clean.But existing fuel filter after filtration also have a lot of objectionable impurities can not by the effective filtering of paper filter element, in these impurity, because ferromagnetic metal impurity phase is to tiny and hard, so metal impurities are in the majority, it is larger to engine damage, and filter after oil liquid pressure and do not meet setting oil pressure, if oil pressure is too low easily cause the parts damages such as oil sprayer, motor.In addition, easily cause fluid to be revealed easily causing energy waste and cause potential safety hazard if oil outlet and oil sprayer bad connection, sealing are poor.
Summary of the invention
According to above technical problem, the utility model provides a kind of fuel filter with hydraulic adjustment device, comprise housing, governor body, filler opening, oil outlet, O type circle, filter core, it is characterized in that: also comprise meticulous filter screen, ring magnet, flame-retardant layer, hydraulic adjustment device, one end of described housing offers filler opening, the other end offers oil outlet, the inwall of described housing is provided with flame-retardant layer, in described housing, filter core is installed, the two ends of described filter core are connected to ring magnet, the both sides of described filter core are separately installed with meticulous filter screen, the side of described ring magnet is connected with hydraulic adjustment device, described hydraulic adjustment device comprises air chamber, fuel oil room, spring, diaphragm, the both sides of described fuel oil room are connected with ring magnet and oil outlet respectively, described fuel oil room is connected with air chamber by diaphragm, in described air chamber, spring is installed, one end of described spring is connected with diaphragm, the other end is connected with spring adjustment seat.
Described housing is demountable structure.
The beneficial effects of the utility model are: the utility model provides a kind of fuel filter with hydraulic adjustment device, original filter cleaner is improved, be provided with ring magnet, effectively can adsorb the metal fillings impurity in fluid, tiny metal fillings impurity is avoided to damage motor with fuel flow, filter core both sides are provided with meticulous filter screen, can, by the colloid filtering in fluid, avoid colloid to block oil outlet or oil sprayer; Hydraulic adjustment device is provided with in housing, regulate the oil pressure filtering after-burning oil, ensure the normal operation of oil supply system, avoid oil pressure too smallly to cause that fuel feeding is slow, oil pressure is excessive causes engine damage and without the need to additional oil pressure regulator, save take up room, cost of production; Be provided with O type circle, make assembling more tight, stable, avoid fluid to reveal and cause energy waste, be provided with flame-retardant layer, avoid because fluid yield temperature raises or the potential safety hazard of impact initiation of external environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, housing-1, filler opening-2, flame-retardant layer-3, filter core-4, ring magnet-5, meticulous filter screen-6, O type circle-7, oil outlet-8, air chamber-9, fuel oil room-10, diaphragm-11, spring-12, spring adjustment seat-13.
Embodiment 1
The utility model provides a kind of fuel filter with hydraulic adjustment device, comprise shell housing 1, filler opening 2, flame-retardant layer 3, filter core 4, ring magnet 5, meticulous filter screen 6, O type circle 7, oil outlet 8, air chamber 9, fuel oil room 10, diaphragm 11, spring 12, spring adjustment seat 13, oil-feed 2 is offered in one end of housing 1, the other end offers oil outlet 8, the inwall of housing 1 is arranged flame-retardant layer 3, in housing 1, filter core 4 is installed, the two ends of filter core 4 are connected to ring magnet 5, the both sides of filter core 4 are separately installed with meticulous filter screen 6, the side of ring magnet 5 arranges hydraulic adjustment device, hydraulic adjustment device comprises air chamber 9, fuel oil room 10, spring 12, diaphragm 11, the both sides of fuel oil room 10 are connected with ring magnet 5 and oil outlet 8 respectively, fuel oil room 10 is connected with air chamber 9 by diaphragm 11, mounting spring 12 in air chamber 9, one end of spring 12 is connected with diaphragm 11, the other end is connected with spring adjustment seat 13.
Embodiment 2
Before using, rely on spring adjustment seat 13 according to set point adjustment its length and elastic force, after housing is installed, fuel oil is entered by filler opening 2, ring magnet 5 effectively can adsorb the metal fillings impurity in fuel oil, meticulous filter screen 6 and filter core 4 can colloid impurity in filtering fuel oil and moisture, avoid impurity with fuel flow damage motor or blocking oil outlet and oil sprayer; Fluid after filtration enters hydraulic adjustment device, when oil pressure does not meet standard, spring vibrations force fluid oil pressure to remain on after in critical field and are discharged by oil outlet 8, ensure the normal operation of oil supply system, avoid oil pressure too smallly to cause that fuel feeding is slow, oil pressure be excessive causes engine damage and without the need to additional oil pressure regulator, save take up room, cost of production; Filler opening 2 and oil outlet 8 are provided with O type circle, make assembling more tight, stable, avoid fluid to reveal and cause energy waste and initiation potential safety hazard; Be provided with flame-retardant layer 3, prevent from fuel oil to be left to causing temperature to raise and the potential safety hazard that causes.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
