Description
Technical field
This utility model belongs to mechanical field, relates to a kind of oil product cleaner, especially a kind of replaceable cartridge, housing reusable filter case assembly.
Background technology
Existing commercially available diesel fuel filter, it mainly has two kinds of forms, one to be overall rotation fitting type, and one is dismantled and assembled replacing filer element type.
It is provided with oil-in and oil-out on overall rotatable filter housing, and is connected with outside oil inlet passage and oil discharge passage by filter block.Filter element is arranged in housing, and housing and filter element are an entirety, can not individually dismantle.In filter element service life to after date, it is necessary to by filter element and housing integral replacing, the filter case after replacing can only be discarded.Having an advantage in that filter block is connected by standard thread with housing, be suitable for standardized production, housing, filter block interchangeability are good.Shortcoming is: firstly, since metal shell is longer than the filter element organic material life-span more than 10 times, but can only disposably discard and cause waste greatly.Secondly as the process recovery process difference of the recovery processing technique of metal and organic material is very big, split cutting is made troubles again when reclaiming, and causes great environmental pollution.3rd, owing to overall rotatable filter is disposable products, consider for cost and service life, that the diameter of filter element and length are done is relatively big, and filter element is little with the gap of housing, and trapped fuel amount is few, add the circulating resistance of cleaner, generally circulating resistance index has just met the upper limit being distinctly claimed in GB, and circulating resistance index is the smaller the better in practice, and this point limits filter effect.
Chinese patent disclosed in 2007 " Split type housing of oil filter 200710110802.8 " discloses a kind of dismountable cleaner, and shell is made up of threaded upper bowl and lower bowl, is provided with sealing ring between upper bowl and lower bowl；Upper bowl is threadeded with the flowline of machine oil base by nut, and the periphery of upper bowl is provided with carrying out the bulge-structure that radial rotating is spacing between upper bowl and machine oil base, and this utility model can carry out filter element replacing after dismantling, it is to avoid waste.But it is complicated to there is structure in Shi Yonging, parts are many, the shortcoming that filter element replacing is constant, and detachable part is on the housing of cleaner, need this position for this, i.e. go up the joint portion of bowl and lower bowl and carry out special sealing, and there are vibrations etc. affect because vehicle is in operation, likely there will be loosening and oil product leakage of this joint portion, cause the inefficacy of whole cleaner.
The cleaner overall dimensions that the most existing different manufacturers produces differs, and installing/dismounting mode also differs, cause the housing of first factory, filter element cannot with the filter block of second factory with the use of situation, user causes certain trouble when changing filter element.Have to change the filter element of different manufacturers often with filter block, housing also together with change, which adds unnecessary expense.
In the course of the work, owing to failing to change the filter element scrapped in time, or the oil product impurity reason such as too much causes blocking to cleaner, causes that system pressure is excessive even bears limit beyond system pressure, brings potential safety hazard.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art; a kind of oil product cleaner is provided; solve the problem that in existing filter case, filter element is non-exchange; housing is made to realize reusing; oil product filter replacement the most of the present utility model is simple, easily operated; and by arranging overflow valve, housing is played overvoltage protection effect.
The purpose of this utility model solves by the following technical programs:
A kind of general rotation fitting type oil product cleaner of the replaceable cartridge with overflow valve, including housing and the filter element being arranged at enclosure interior, it is provided with thread connection plate between described housing oral area and filter element oil-out, described thread connection plate is the disc structure corresponding to housing oral area shape, thread connection plate be provided centrally with dock tapped through hole, be connected with the oil discharge passage of filter base；Within one week, it is provided with some oil-feed through holes around tapped through hole on thread connection plate, and is connected with the oil inlet passage on filter base；Described housing bottom is provided with elastic supporting member for supporting optical member, described thread connection plate outer ring is provided with some symmetrical double wedges, housing oral area is provided with the groove matched with double wedge, the circumferential yardstick of described double wedge is less than the circumferential yardstick of groove, and under the effect of described elastic supporting member for supporting optical member, thread connection plate overlays on filter element oil-out；Being provided with overflow valve on cleaner, pressure realizes the discharge of liquid in housing time excessive in the housing.
In the general rotation fitting type oil product cleaner of the above-mentioned replaceable cartridge with overflow valve, the bottom of the oral area of housing is provided with the locating slot matched with described double wedge, and rotation and movement to thread connection plate carry out spacing.
