Abstract
The utility model discloses a kind of oil return filter safety valve components, including valve and valve base, wherein valve is fixed on the middle part of end cap by spring, the middle part of the end cap is equipped with through-hole, valve base is sheathed on the outside of valve and the valve base and end cap pass through rivet, it is sealed between valve and valve base by sealing ring, the valve base top position opposite with valve is equipped with through-hole, the strainer being fixedly connected with valve base is equipped on the outside of the through-hole, for after valve is opened oil liquid entered inside filter by the strainer on valve base.The utility model has many advantages, such as that high reliablity, long service life, Control platform are good, it is wide to be applicable in flow pressure-difference range, effectively extends the cycle of operation of fuel pump or mechanical hydraulic unit system.
Description
Technical field
The utility model belongs to engine oil filter technical field, and in particular to a kind of oil return filter safety valve group
Part.
Background technique
In existing fuel pump or mechanical hydraulic unit system, pressure limit valve is often used as safety valve, uses
To protect fuel pump or the fuel by-pass under specified requirements is realized in limitation maximum pressure.Oil return filter is using a period of time
Afterwards, the filter effect of filter core is deteriorated, and filter core inside and outside differential pressure is caused to increase, when inside oil pressure reaches certain difference beyond outside oil pressure
After can promote safety valve that spring force is overcome to act on, and then safety valve is promoted to open, connection inside and outside filter core is until combustion
Oil pressure reaches balance, and the dirt of filtering retention can reenter fuel pump or machinery from safety valve on the inside of filter core during this
In hydraulic device system, the service life of equipment is influenced.
Summary of the invention
There is provided a kind of oil return filter peaces being simple in structure and reasonable in design for the technical issues of the utility model solves
Full valve assembly.
The utility model adopts the following technical scheme that solve above-mentioned technical problem
A kind of oil return filter safety valve component, it is characterised in that including valve and valve base, wherein valve passes through bullet
Spring is fixed on the middle part of end cap, and the middle part of the end cap is equipped with through-hole, and valve base is sheathed on the outside of valve and the bottom of the valve base
Portion is riveted by rivet and end cap, is sealed between valve and valve base by sealing ring, the valve base top position opposite with valve
Installed through-hole, the strainer being fixedly connected with valve base be equipped on the outside of the through-hole, for after valve is opened oil liquid pass through valve
Strainer on seat enters inside filter.
Further preferably, the strainer is welded on the side wall of valve base by way of roll welding.
Further preferably, the valve is Three-claw type valve.
The utility model has the advantages that the utility model has high reliablity, uses compared with prior art
Service life is long, Control platform is good, is applicable in the advantages that flow pressure-difference range is wide, by adding strainer on the outside of valve base, effectively extends
Cycle of operation of fuel pump or mechanical hydraulic unit system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the usage state diagram of the utility model.
In figure: 1- valve, 2- valve base, 3- spring, 4- end cap, 5- rivet, 6- sealing ring, 7- strainer.
Specific embodiment
The technical solution of the utility model is described in detail in conjunction with attached drawing, a kind of oil return filter safety valve component, including
Valve 1 and valve base 2, wherein valve 1 is fixed on the middle part of end cap 4 by spring 3, and the middle part of the end cap 4 is equipped with through-hole, valve
Seat 2 is sheathed on the outside of valve 1 and the bottom of the valve base 2 and is riveted by rivet 5 and end cap, leads between valve 1 and valve base 2
The sealing of sealing ring 6 is crossed, 2 top of the valve base position opposite with valve 1 is equipped with through-hole, is equipped on the outside of the through-hole solid with valve base 2
Surely the strainer 7 connected, for after the unlatching of valve 1 oil liquid entered inside filter by the strainer 7 on valve base 2, the filter
Net 7 is welded on the side wall of valve base 2 by way of roll welding.
The utility model has that high reliablity, long service life, Control platform are good, it is wide etc. excellent to be applicable in flow pressure-difference range
Point, by adding strainer on the outside of valve base, effectively prevent filtering retention on the inside of filter core dirt can from safety valve again into
Enter in fuel pump or mechanical hydraulic unit system, and then extends the cycle of operation of fuel pump or mechanical hydraulic unit system.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is practical new not departing from this
Under the premise of type spirit and scope, there are also various changes and modifications, these changes and improvements both fall within requirement and protect the utility model
The scope of the utility model of shield.
