Description
Technical field
The utility model is related to a kind of oil filter of Anti-back overflow, relates generally to oil filter field.
Background technology
Carbon distribution and gelatinous precipitate, water being oxidized in engine working process, under metal filings, dust, high temperature etc. is no
It is disconnected to be mixed into lubricating oil.The effect of oil filter is exactly to filter these mechanical admixtures and colloid, protects oily cleaning to be lubricated, extension
Its useful life.Oil filter should have filtering ability strong, and circulating resistance is small, the performance such as service life length.When impurity is in filter
Excessively rear on clear device filter core easily to block filter core, currently existing scheme is that a by-passing valve is added on cleaner, in cleaner
By-passing valve is opened after being blocked, and prevents that completely no machine oil from being filtered into each unit with this.But this solution
It is the machine not by filtering after all although still organic oil enters each unit and is operated after cleaner is blocked
Oil, the infringement to each unit can be very serious, does not have redundant filter structure.
Utility model content
For above the deficiencies in the prior art, the utility model proposes a kind of oil strainer of the Anti-back overflow provided with redundant filter
Clear device.
To reach above-mentioned purpose, the technical solution of the utility model is：Including columnar housing, the middle part in housing
Level will be divided into conventional filtering chamber and standby filtering chamber provided with dividing plate in housing, commonly use the upper end port of filtering chamber provided with upper
The center of circle is provided with oil outlet in the middle part of lid, upper lid, and fuel feed hole is provided with the periphery of oil outlet, provided with only at the fuel feed hole on the inside of upper lid
Return valve, be vertically arranged in housing and be coaxially arranged with conventional filter cylinder, upper end outer circumferential of the conventional filter cylinder provided with fixed plate and with
Oil outlet is connected, and the lower end of conventional filter cylinder is fixed on dividing plate, is cased with conventional filter core in the excircle of conventional filter cylinder, is commonly used filter core
Upper end be fixed in fixed plate, the lower end of conventional filter core is fixed on dividing plate, in the axle of the conventional filter cylinder of middle part correspondence of dividing plate
Hole is provided with some spill ports, and dividing plate upper surface correspondence spill port is provided with capping, the spring catch being sliding combined with vertically on dividing plate,
The upper end of spring catch be connected with capping, spring catch will cover downwardly against, provided with standby filter core below dividing plate, the axle center of filter core
Hole correspondence spill port is set, and is provided with sliding ring and spring in the excircle of standby filter core, spring is under sliding ring
End is by sliding ring upwards against in spill port outer circumferential end face provided with some filter openings, the conventional filter core of filter opening connection on dividing plate
And sliding ring.
Technical principle of the present utility model is as follows：When conventional filter core is normally used, due to sliding ring and envelope
Lid under the action of the spring respectively blocks filter opening and spill port, therefore machine oil will not be entered in standby filtering chamber.When conventional
When filter core is blocked, under the effect of the pressure, sliding ring is pressed off, and machine oil enters standby filtering intracavitary, Ran Houjing
Cross standby filter core progress filtering machine oil to pass through after standby filter core and then press off cover plate upwards from axle center hole, machine oil enters through cover plate
Into conventional filter cylinder, oil outlet is finally flowed out.
The beneficial effects of the utility model are as follows：Due to sliding ring and the cooperation of capping, do not blocked up in conventional filter core
When plug, standby filter core will not touch machine oil completely, i.e., will not be filtered, and can keep the cleanliness of standby filter core,
Improve the life-span of standby filter core.When conventional filter core is blocked, even if standby filter core can be to replace work, it is ensured that machine oil
Proper flow.
Further, the upper end of sliding ring is fixed with seal gasket, improves the sealing effectiveness of sliding ring.
Further, drain path is additionally provided with below standby filter core, pressure will when standby filter core is also blocked
Sliding ring is pulled down, and final drain path connection axle center hole and standby filtering chamber, machine oil are flowed directly out without filtering
Oil outlet.
