Abstract
The utility model discloses a kind of check-valves anti-reflux mechanisms for filter, it include check valve body, check valve body top is equipped with upper end cover, fixing sleeve is equipped with thread plate in the annular oral area of upper end cover, thread plate is equipped with fuel feed hole, and the annular oral area fixed sleeves of upper end cover are equipped with check-valves；The check-valves includes tubular valve body, and integrated horn-like valve body is arranged with outside tubular valve body, and the back side of the horn-like valve body is equipped with several reinforcing ribs being spaced apart；The lower surface that the annular upper end face of the horn-like valve body is located at fuel feed hole outside left with thread plate fits.The utility model is simple in sturcture, ingenious in design, and the purpose for preventing machine oil from flowing back can be realized by simply increasing a reinforcing rib, extend the service life of check-valves, meet the use demand of enterprise.
Description
Technical field:
The utility model relates to filter fields, relate generally to a kind of check-valves anti-reflux mechanism for filter.
Background technique:
Part vehicle the leakage rate of check-valves is required it is relatively high, traditional check-valves in the case where not changing material very
Difficulty reaches requirement.Because of the pressure that conventional check valves can open one, check-valves when machine oil enters filter, with non-return
The multiple either on or off of valve, traditional check-valves will appear partial failure phenomenon, and service life is shorter.
Utility model content:
The utility model aim is exactly in order to make up the defect of prior art, it is anti-to provide a kind of check-valves for filter
Flow back mechanism, it is equipped with reinforcing rib at the back of check-valves, has a reversed support force to the back of check-valves, can beat repeatedly
Do not occur failure phenomenon, long service life after opening.
The utility model is achieved through the following technical solutions:
A kind of check-valves anti-reflux mechanism for filter, includes check valve body, it is characterised in that: check-valves valve
Body top is equipped with upper end cover, and fixing sleeve is equipped with thread plate in the annular oral area of upper end cover, and thread plate is equipped with fuel feed hole, on
The annular oral area fixed sleeves of end cap are equipped with check-valves；The check-valves includes tubular valve body, and one is arranged with outside tubular valve body
The back side of the horn-like valve body of body, the horn-like valve body is equipped with several reinforcing ribs being spaced apart；The horn-like valve body
The lower surface that annular upper end face is located at fuel feed hole outside left with thread plate fits.
A kind of check-valves anti-reflux mechanism for filter, it is characterised in that: installed on the thread plate
There is sealing ring fixed plate, exterior seal ring is installed in sealing ring fixed plate.
After machine oil enters check-valves from fuel feed hole position, horn-like valve body position on check-valves and thread plate it
Between expose gap under the pressure of machine oil, machine oil flows into inside filter from gap position.Since improved check-valves is at it
The back side increases reinforcing rib, and purpose is played a supporting role, and increases the adhesive force of check-valves after installation, to reduce returning for machine oil
Stream.
Improved check valve design is inspiration by the skeleton of umbrella, although umbrella short time during blowing and beating windward
It will appear buckling phenomenon, but immediately restored after becalming, improvement is made to check valve structure by this principle, band is reinforced
The pressure that the check-valves of muscle can open one, check-valves when machine oil enters filter, as multiple either on or off is traditional
Check-valves will appear partial failure phenomenon, but the check-valves with reinforcing rib has a reversed branch after multiple opening, closing
Support force.
The utility model has the advantages that:
The utility model is simple in sturcture, ingenious in design, by simply increase a reinforcing rib can be realized prevent machine oil return
The purpose of stream extends the service life of check-valves, meets the use demand of enterprise.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the main view of check-valves.
Fig. 3 is the bottom view of check-valves.
Specific embodiment:
Referring to attached drawing.
A kind of check-valves anti-reflux mechanism for filter, includes check valve body 4, and 4 top of check valve body is set
There is upper end cover 5, fixing sleeve is equipped with thread plate 6 in the annular oral area of upper end cover 5, and thread plate 6 is equipped with fuel feed hole 7, upper end
The annular oral area fixed sleeves of lid 5 are equipped with check-valves 8；The check-valves includes tubular valve body 1, is arranged with outside tubular valve body 1
The back side of the horn-like valve body 2 of one, the horn-like valve body 2 is equipped with several reinforcing ribs 3 being spaced apart；The horn-like valve
The lower surface that the annular upper end face of body 2 is located at fuel feed hole outside left with thread plate fits.
Sealing ring fixed plate 9 is installed on thread plate 6, exterior seal ring 10 is installed in sealing ring fixed plate 9.
