Description
Technical field
The utility model belongs to valve technology field, relates to a kind of bypass valve, especially relates to a kind of novel bypass valve for oil filter.
Background technique
Oil filter is the important spare part of on combustion engine powered equipment such as vehicle, engineering machinery, boats and ships, internal-combustion engine is in operation process, machine oil in lubrication system, can also impurity on cleaning components while lubricating detail, prevents impurity from damaging part.The effect of oil filtration is the impurity in filtering machine oil, guarantees that machine oil cleans, prevents impurity secondary pollution component, and protection gas engine part, extends its working life.
Generally for the design of oil filter, under the prerequisite meeting performance requirement, boundary dimension is the smaller the better, like this can conserve space again can be cost-saving.And bypass valve is as the indispensable part of oil filter, the bypass valve used in oil filter is for when in oil filter, filter core is blocked, filter cleaner filler opening and oil outlet reach certain certain pressure difference, bypass valve is opened, machine oil is without filter core, directly flow to lubrication main oil gallery, thus ensure the normal lubrication of whole motor.At present, the bypass valve of most of oil filter is designing and producing in process, basic employing helical spring structure, but this helical spring structure takes up room greatly, and during spring reset, produce very strong spring force to sealing gasket, processing ease makes the contact position of sealing gasket and spring loosen frequently.
Model utility content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of compact structure is provided, effectively can reduce the novel bypass valve for oil filter of height dimension.。
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel bypass valve for oil filter, this bypass valve comprises lower end cap, pad, flathead rivet and cup spring, described lower end cap circle centre position is provided with variable cross section ladder mounting hole, described cup spring is arranged in mounting hole, and be fixedly connected with lower end cap by flathead rivet, described pad is arranged between lower end cap and cup spring.
Described cup spring circle centre position is provided with fixed hole, and cup spring is fixed on described lower end cap through fixed hole by described flathead rivet.
Described cup spring is along the circumferential direction also evenly laid with three cantilever spring.
Described three cantilever spring mutually isolated is laid on described cup spring.
Described pad is circular gasket, and the circle centre position of this pad is provided with the attachment hole matched with flathead rivet.
Bypass valve of the present utility model adopts cup spring to replace helical spring of the prior art, and when pressure reduction reaches the cracking pressure of cup spring, cup spring struts pad, bypass valve is opened, machine oil, without filtration, directly flows to lubrication main oil gallery, thus ensures the normal lubrication of whole motor.
Compared with prior art, the utility model has following characteristics:
1) adopt cup spring to replace helical spring of the prior art, effectively can save installing space, be conducive to the height reducing apparent size, save processing cost;
2) adopt the cup spring with cantilever spring, flexible, elasticity is strong, and structure is more stable, long service life;
3) structure is simple, and compact, practical, stability in use is good, has good application prospect.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As shown in Figures 1 to 3, a kind of novel bypass valve for oil filter, this bypass valve comprises lower end cap 1, pad 2, flathead rivet 3 and cup spring 4, lower end cap 1 circle centre position is provided with variable cross section ladder mounting hole 7, cup spring 4 is arranged in mounting hole 7, and be fixedly connected with lower end cap 1 by flathead rivet 3, pad 2 is arranged between lower end cap 1 and cup spring 4.
Cup spring 4 circle centre position is provided with fixed hole 8, and cup spring 4 is fixed on lower end cap 1 through fixed hole 8 by flathead rivet 3; Cup spring 4 is along the circumferential direction also evenly laid with three cantilever spring 9, and this three cantilever spring 9 is mutually isolatedly laid on cup spring 4.
Pad 2 is circular gasket, and the circle centre position of this pad 2 is provided with the attachment hole 10 matched with flathead rivet 3.
In the present embodiment, bypass valve adopts cup spring 4 to replace helical spring 5 of the prior art, when pressure reduction reaches the cracking pressure of cup spring 4, cup spring 4 struts pad 2, bypass valve is opened, machine oil, without filtration, directly flows to lubrication main oil gallery, thus ensures the normal lubrication of whole motor.
Fig. 4 is existing bypass valve, comprises lower end cap 1, the valve chest 6 be connected with some end cap 1 and the helical spring 5 be set on valve chest 6, wherein, is also provided with pad 2 between helical spring 5 and lower end cap 1.Owing to adopting helical spring 5 structure, this helical spring 5 structure takes up room greatly, and the accommodating helical spring 5 of sufficiently high size ability must be designed, be unfavorable for the volume reducing bypass valve, and helical spring 5 is when resetting, produce very strong spring force to sealing gasket, processing ease makes the contact position of sealing gasket and helical spring 5 loosen frequently, affects the normal use of bypass valve.
