Description
Technical field
This utility model belongs to oil filter technical field, particularly relates to the thread plate group of a kind of oil filter
Part.
Background technology
There is plurality of impurities in car engine lubrication system, these impurity include that the external world brought into by filling engine oil is miscellaneous
The wadding that the metal fillings of matter, engine friction pair relative motion generation and machine oil produce in engine lubrication system hot operation
Shape thing and jelly etc..The purpose that oil filter exists is contemplated to filter these affects the harmful miscellaneous of service life of aeroengine
Matter.Existing oil filter generally uses rubber seal to enter in thread plate assembly between thread plate and metal seal
Row seals, also with the presence of the structure using fluid sealant to substitute rubber seal.These with oil filter oil-feed only seal structure
Return valve to be used together and play when electromotor is shut down machine oil withdrawing oil drain pan in prevention lubricating system, it is ensured that open next time at electromotor
Friction pair during having enough machine oil to carry out lubricating movements in lubricating system time dynamic.The rubber used in existing thread plate assembly
Glue sealing ring and fluid sealant structure have the disadvantage that 1) thread plate and metal seal be equal when part processing and assembling riveting
There is deviation, the control to fluid sealant usage amount is made troubles, and easily occurs that glue-spread is big, exposes and affects oil filter U.S.
See；Glue-spread is little, it is impossible to form situation about effectively sealing；2) development of existing vehicle engine machine technology, particularly in-cylinder direct-jet
The application of technology, requires to improve a lot to the temperature tolerance of the part of lubricating system, adds the material cost of fluid sealant；3) send out
The raising that lubricating system components temperature tolerance is required by motivation, adds the material cost of rubber seal；4) different use rings
Border needs to use the rubber seal of unlike material, causes part management cost to increase, it is also possible to owing to part accumulates improper drawing
Play waste.
Utility model content
This utility model is in order to solve weak point of the prior art, it is provided that a kind of low cost, compact conformation, sealing effect
The best, the thread plate assembly of working stability, oil filter applied widely.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that the threaded cap of a kind of oil filter
Board component, including cylindrical circular housing, housing upper opening part is provided with thread plate, and thread plate is flange plate structure, spiral shell
Being tightly connected between stricture of vagina cover plate circumference and inner walls, thread plate center offers threaded mounting hole, along circle on thread plate
Circumferential direction uniform intervals offers some fuel feed holes, and the riveting of thread plate upper surface has metal seal, metal seal circumferential periphery
Use flanging mode to be tightly connected along with housing upper edge, be provided with sealing between the flanging junction of metal seal and housing and be coated with
Glue-line, is compressed by sealing gasket between thread plate upper surface and metal seal lower surface and seals, and sealing gasket is by oil strainer paper wood
Material is made, and is provided with check-valves, check-valves and thread plate lower surface press fit below thread plate.
The metal seal concave downward of tuck portion radially inner side formed annular seal groove, the vertical section of seal groove in
Square structure, is embedded with sealing ring in seal groove.
The radial inner end of the metal seal at fuel feed hole is bent through downwards fuel feed hole and is riveted on thread plate.
Check-valves outer edge all raises up, and bossing is convex structure, convex structure and thread plate following table
Face compresses and seals.
Using technique scheme, this utility model has the advantages that
1, being positioned at fuel feed hole upper section correspondence in metal seal to be turned over downwards, turnover part passes downwards fuel feed hole riveting
It is connected on thread plate, and metal seal circumferential periphery uses flanging mode to fix along with housing upper edge, metal seal
And it is provided with sealing rubberised layer between the flanging junction of housing, uses above-mentioned connected mode, compact conformation and consolidating, and close
Seal effective.
2, in thread plate assembly, sealing gasket between thread plate and metal seal uses oil filter paper material to make, with
The material of oil filter filter course is identical, there is not the risk of stock waste；Sealing gasket can be processed into solid shape,
Avoid the consumption using fluid sealant to bring to control risk；The material used is single, it is to avoid use rubber seal is brought
Batch mixing risk；Using in high oil temperature lubricating system, cost is less than rubber seal and fluid sealant.
3, check-valves compresses sealing, and metal envelope by the convex structure on its circumferential edge edge and thread plate lower surface
Compressing between circle and thread plate and be sealed with sealing gasket, therefore check-valves and sealing gasket together form machine when electromotor is shut down
Oil non-return seals.
4, offer seal groove in metal seal, in seal groove, be embedded with sealing ring so that the connection of metal seal is more
Reliable and stable.

Detailed description of the invention
As Figure 1-4, the thread plate assembly of a kind of oil filter of the present utility model, including cylindrical circular shell
Body 1, is provided with thread plate 2 at housing 1 upper opening, thread plate 2 is in flange plate structure, in thread plate 2 circumference and housing 1
Being tightly connected between wall, thread plate 2 center offers threaded mounting hole 3, uniformly spaced in the circumferential direction on thread plate 2
Being provided with some fuel feed holes 4, the riveting of thread plate 2 upper surface has metal seal 5, metal seal 5 circumferential periphery edge and housing 1 top
Edge uses flanging mode to be tightly connected, and is provided with sealing rubberised layer, screw thread between the flanging junction of metal seal 5 and housing 1
Being compressed by sealing gasket 6 between cover plate 2 upper surface and metal seal 5 lower surface and seal, sealing gasket 6 is by oil filter paper material system
Become, below thread plate 2, be provided with check-valves 7, check-valves 7 and thread plate 2 lower surface press fit, threaded mounting hole 3 with only
Return valve 7 to be connected.Sealing rubberised layer is this area existing conventional techniques, not shown.
Metal seal 5 concave downward of tuck portion radially inner side forms the seal groove 8 of annular, vertically cutting of seal groove 8
Face is square structure, is embedded with sealing ring 9 in seal groove 8.
The radial inner end of the metal seal 5 at fuel feed hole 4 is bent through downwards fuel feed hole 4 and is riveted on thread plate 2
On.
Check-valves 7 outer edge all raises up, and bossing is convex structure 10, convex structure 10 and thread plate
2 lower surfaces compress and seal.
In use, during electromotor work, machine oil is entered by fuel feed hole 4 and is promoted check-valves 7, non-return this utility model
Valve 7 moves down generation gap between thread plate 2, and machine oil enters in oil filter from this gap, at oil filtration
The impurity in machine oil is filtered under the effect of device；When electromotor is shut down, due to the check-valves 7 convex structure by its circumferential edge edge
10 compress with thread plate 2 lower surface and to seal, and metal seal 5 is riveted on thread plate 2, and metal seal 5 and threaded cap
Compressing between plate 2 and be sealed with sealing gasket 6, therefore check-valves 7 and sealing gasket 6 together form the non-return sealing of machine oil, and metal seals
Enclose 5 circumferential peripheries to be tightly connected along using flanging mode to be fixed with housing 1, and sealing ring 9 is embedded in metal seal 5
Seal groove 8 in so that structure is more stable, and sealing effectiveness is more preferable.
Shape of the present utility model, material, structure etc. are not made any pro forma restriction, every foundation by the present embodiment
Any simple modification, equivalent variations and the modification that above example is made by technical spirit of the present utility model, belongs to this reality
Protection domain by new technique scheme.
