Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of oil filter body provided by the utility model, including cylinder open at one end
1, external screw thread 1.1 is offered on the lateral wall of opening in the cylinder 1, external screw thread 1.1 is for being threadedly coupled described in lower section
Cover closing member 7, offer oil inlet 2 in the bottom of cylinder 1.
Oil inlet pipe 3 is welded in one end of oil inlet 2, central tube 4 is welded in the other end of oil inlet 2, in the central tube 4
Centre be equipped with one group of through-hole 4.1, i.e., central tube 4 close to opening both ends side wall be it is solid, central tube 4 is welded on
Bottom in the cylinder 1, is successively socketed spring 5 and backing plate 6 on central tube 4.
The bottom of the cylinder 1 is welded in one end of spring 5, and the other end of spring 5 welds the backing plate 6, and the backing plate 6 is
Circular slab, the diameter of backing plate 6 is identical as the internal diameter of the cylinder 1, offers through hole 6.1, through hole at the center of backing plate 6
6.1 diameter is identical as the outer diameter of the central tube 4, the central tube 4 described in grafting in through hole 6.1, in 6 annular sidewall of backing plate
It is equipped with annular groove 6.2, is socketed ring type seal in annular groove 6.2.
When installing filter core, filter core is socketed in the outside of central tube 4, filter core is pressed down against spring 5, make backing plate 6 also to
Lower movement is socketed in central tube 4 without the place of through-hole 4.1, keeps filter core Chong Die with the realization of through-hole 4.1, i.e., machine oil is passing through
When central tube 4, it can only flow into filter core by through-hole 4.1.
It is threadedly coupled cover closing member 7 in the opening of cylinder 1, cover closing member 7 covers the opening of the cylinder 1, in cover closing member 7
Valve body part 8 is connected, the cover closing member 7 includes circle box 7.1 open at one end, welds flowline 7.2 in the bottom of circle box 7.1, out
Oil pipe 7.2 is connected to inside the round box 7.1, welds the valve body part 8 in circle box 7.1, is welded in opening one end of circle box 7.1
Connected nut 7.3, setting nut 7.3 are convenient for opening using spanner or tightening cover closing member 7, and nut 7.3 is coaxially set with the round box 7.1
It sets, nut 7.3 is threadedly coupled the external screw thread 1.1.
The valve body part 8 includes round tube 8.1, by-passing valve 8.2 is arranged in round tube 8.1, in one end connection method of round tube 8.1
Orchid 8.3, the diameter of flange 8.3 is identical as the internal diameter of the round box 7.1, and flange 8.3 is welded on the inner wall of the round box 7.1,
One group of recirculation hole 8.4 is equipped on flange 8.3.
It uses principle: when installing filter core, first unscrewing cover closing member 7 with spanner, filter core is socketed in the outside of central tube 4,
Then again by 7 upper round tube of cover closing member, 8.1 grafting into central tube 4, the outer spiral shell on cylinder 1 is threadedly coupled finally by nut 7.3
Line 1.1, so that cover closing member 7 to be covered to the opening of the cylinder 1, when in use, machine oil enters central tube 4 by oil inlet pipe 3
It is interior, then entered in filter core from the through-hole 4.1 on central tube 4, filtering of the machine oil through filtration core, then by recirculation hole 8.4, most
It is flowed out afterwards from flowline 7.2, when filter core is through after after a period of time, since no replacement in time will cause blocking, at this moment center
Machine oil in pipe 4 cannot pass through the filtering of filter core, can only be deposited in central tube 4, can wash open when oil pressure reaches to a certain degree
By-passing valve 8.2 is directly flowed into flowline 7.2 from round tube 8.1, so as not to engine cannot get at runtime the lubrication of machine oil from
And cause bigger damage.
