Specific embodiment
To keep the purpose of this utility model, structure and advantage clearer, below in conjunction with attached drawing to the utility model reality
The mode of applying is described in further detail.
As shown in Figure 1-3, a kind of dry oil filter was equipped in filtration body 1 including the filtration body 1 being obliquely installed
Filter cylinder body, oil inlet 3 lead to filtration barrel body, and oil outlet 4 leads to filtration body 1, and drier oil enters filtration barrel body from the bottom up.
Wherein, filtration barrel body is divided into inner cylinder 6 and outer barrel 7.Connector 15 is installed, connector 15 plugs at the top of inside and outside cylinder
On the plate 9 being fixedly connected with filtration body 1.It is equipped with detachable end 2 above plate 9, is set between end cap 2 and plate 9
There is the gasket seal 7 connecting by the first spring 8 with end cap 2.Meanwhile the bottom of inside and outside cylinder is fixedly connected with ring-shaped rubber
Plug 16, and be plugged in the slot 17 of 1 bottom of filtration body by ring-shaped rubber plug 16, by constantly tightening end cap, gasket
Piece can be pressed down against connector under the promotion of the first spring, thus being pressed onto slot tightly by filter cylinder.
In addition, being additionally provided with piston hole in filtration body 1, piston 13, the bottom of piston 13 and piston hole are equipped in piston hole
Between be equipped with second spring 14.Oil discharge passage 12 is offered on piston hole side wall, oil discharge passage 12 leads to oil outlet 4.
Wherein, the filter opening aperture of inner cylinder 6 is greater than the filter opening aperture of outer barrel 5.
Referring to Fig. 3, is set on plate 9 there are two the circumferential rebate being arranged concentrically, respectively correspond to the internal plug seat 902 of inner cylinder
With the outer jack 901 of corresponding outer barrel 5.And to be additionally provided with groove 903 convenient for extracting filtration barrel body, on circumferential rebate.
Preferably, end cap 2 is threadedly coupled with filtration body 1.
Preferably, the size of gasket seal 7 and plate 9 are equal in magnitude.
Specifically, referring to fig. 2, the cross section of ring-shaped rubber plug 16 and slot 17 is isosceles trapezoid wide at the top and narrow at the bottom, and
The cross section base angle of ring-shaped rubber plug 16 is greater than the cross section base angle β of slot 17.So, when connector compression makes filtration barrel body
When constantly pushing enters slot, since the inclined-plane inclination of rubber stopper is big compared with slot, the connection sealing of rubber stopper and slot is more preferable.
Further, oil strain space is formed between filtration body and filtration barrel body, when second spring 14 is in free state
When, oil discharge passage 12 and the connector of piston hole side wall do not lead to oil strain space.
Further, oil inlet 3 is led to by oil inlet passage and filtration barrel body, and oil inlet passage bottom offers sewage draining exit
10, blowdown valve 11 is installed at sewage draining exit 10.
Certainly, the preferred embodiment of only the utility model described above, is not limitation of the utility model, this
The variations, modifications, additions or substitutions that the those of ordinary skill of technical field is made in the essential scope of the utility model,
Belong to the protection scope of the utility model.
