Description
Technical field
The present invention relates to a kind of centrifugal rotor to filter device, is filtered more particularly, to a kind of centrifugal rotor with bidirectional cutting valve
Device.
Background technology
Centrifugal rotor filter is the impurity in machine oil is attached in rotor by centrifugal force caused by rotor high speed rotation
On wall, the filter that allows impurity to be separated from machine oil.Lubricating oil pump extracts machine oil from fuel tank and is delivered to centrifugal rotor
Filter, machine oil sprays from rotor nozzle carrys out drive rotor rotation so as to produce reaction force.Under normal circumstances, rotor filter needs are cut
Disconnected valve come control machine oil stream enter rotor filter in uninterrupted, stop valve is opened in the case where machine oil reaches certain pressure, but can not be controlled
Oil flow rate size after system is opened, can be caused to damage when engine oil pressure is excessive to rotor, more seriously, be started due to taking
The excessive oil flow rate of owner's oil duct so that engine does not have enough machine oil to go to lubricate, and causes engine scuffing.Particularly with
State's intrinsic motivation, cold start-up pressure phenomenon can be all run into, using existing stop valve, it is easy to cause rotor filter inner rotator damage
It is bad.
The content of the invention
The purpose of the present invention is exactly to provide carrying for a kind of controllable engine oil pressure and flow to solve the above problems
The centrifugal rotor filter device of bidirectional cutting valve.
The purpose of the present invention is achieved through the following technical solutions：
A kind of centrifugal rotor filter device with bidirectional cutting valve, including upper lid, lower house and rotor, described upper lid lead to
Cross bolt to be connected with lower house, described rotor is fixed in upper lid and lower house by rotating shaft, and described lower house bottom is set
There is in-line, bidirectional cutting valve is provided with described in-line, described bidirectional cutting valve is provided with control bidirectional cutting valve
Spring, different elastic springs can be set control machine oil enter flow and pressure.
Described bidirectional cutting valve is ladder club shaped structure, including anterior big pole and the small pole at rear portion.
Described spring is set on the small pole of bidirectional cutting valve, on the one hand the small pole of stock effectively protects spring,
Spring is avoided to be damaged by excessive pressure, on the other hand, it is ensured that the radial positioning of spring, to prevent dislocation from influenceing valve
Operation pressure interval.
The length ratio of described big pole and small pole is 1：1-1.5, the diameter ratio of big pole and small pole is 2-2.5：
1。
Described big pole is provided with duct vertically, is along the circumferential direction provided with ring groove on big pole, it is contemplated that flow resistance
Influence, ring groove is provided with least two circular holes, and the quantity of circular hole can be set according to specific flow, pressure.
The diameter ratio of the diameter in the duct and big pole is 2：3-4, the length in duct are less than the length of big pole.
Described in-line porch is provided with plug.
In the use of the present invention, engine starts, as oil flow rate increases, pressure increase, bidirectional cutting valve is by machine oil
Elapsed inside toward inflow pipeline, when pressure reaches certain value, the circular hole on bidirectional cutting valve aligns with rotor channel entrance, valve
It is just turned on, machine oil enters internal rotor, and drive rotor rotates, and centrifugal force caused by rotor rotation adheres to the impurity in machine oil
In rotor inner wall, the machine oil after filtering delivers to engine oil tank by oil return opening；It is two-way to cut but if oil flow rate continues to increase
Disconnected valve is further toward moving inside inflow pipeline, and the circular hole on bidirectional cutting valve staggers with rotor channel entrance, and valve is closed, this
When almost no machine oil flow into rotor filter, only the machine oil of desired flow pressure could enter rotor in, so as to reach protection turn
The effect of son filter.Can be by setting different elastic springs to design oil flow rate and pressure limit, it is ensured that into rotor
Machine oil is in scope of design.
Compared with prior art, the present invention is by setting bidirectional cutting valve, when flow is smaller, especially in cold start-up,
The machine oil of main oil gallery is not take up, to ensure that main oil gallery has enough machine oil to go to lubricate, protects engine；When flow is larger,
Excessive flow is limited, rotor filter is not impacted, protects the rotor of inside.Present apparatus use range is wide, for various
The engine of type, no matter the flow pressure size of lubricating oil pump, can run well, two-way valve can ensure enter rotor filter
Flow pressure is run in certain section, by spring come the stroke size of control valve.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
It is a kind of with bidirectional cutting valve centrifugal rotor filter device, as Figure 1-5, including upper lid 1, lower house 3 and turn
Son 4, upper lid 1 is connected by bolt 2 with lower house 3, and rotor 4 is fixed in upper lid 1 and lower house 3 by rotating shaft 5, lower house 3
Bottom is provided with in-line 9, and the porch of in-line 9 is provided with plug 6, bidirectional cutting valve 7 is provided with in-line 9, two-way
Stop valve 7 is provided with the spring 8 of control bidirectional cutting valve 7, and bidirectional cutting valve 7 is ladder club shaped structure, including anterior big pole
71 and the small pole 72 at rear portion, spring 8 be set on the small pole 72 of bidirectional cutting valve, the small pole 72 of stock effectively protects bullet
Spring 8, avoids spring from being damaged by excessive pressure.The length ratio of big pole 71 and small pole 72 can be 1：1-1.5 this reality
Example is applied as 1:1, the diameter ratio of big pole 71 and small pole 72 can be 2-2.5：1, the present embodiment 2.5：1.The big edge of pole 71
It is axially arranged with duct 73, ring groove 74 is along the circumferential direction provided with big pole 71, ring groove 74 is provided with four circular holes 75,
The diameter ratio of the diameter in duct 73 and big pole 71 can be 2：3-4, the present embodiment 2:3.6, the length in duct 73 is less than
The length of big pole 71.
When in use, engine starts, and as oil flow rate increases, pressure increase, bidirectional cutting valve 7 is by machine oil toward oil-feed
The inside of pipeline 9 elapses, and when pressure reaches certain value, the circular hole 75 on bidirectional cutting valve 7 aligns with rotor channel entrance, and valve is firm
Good to open, machine oil enters inside rotor 4, and drive rotor 4 rotates, and rotor 4, which rotates caused centrifugal force, makes the impurity in machine oil attached
