Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figs. 1-2, one kind cutting slotting vehicle hydraulic system monoblock type valve block, including valve block 1,1 one side surface of valve block
Fixed to offer No.1 oil inlet 2,2 side of the No.1 oil inlet fixation offers No. two oil inlets 3, No. two oil inlets
3 sides are fixed to offer No. three oil inlets 4, and the fixation of another side surface of the valve block 1 offers No.1 oil outlet 5, the No.1
5 side of oil outlet is fixed to offer No. two oil outlets 6, and the fixation of 6 side of No. two oil outlets offers No. three oil outlets 7, institute
It states the fixation of 1 upper surface of valve block and offers No. four oil outlets 8, the fixation of 8 side of No. four oil outlets offers No. five oil outlets 9,
The fixation of 9 side of No. five oil outlets offers No. six oil outlets 10, and the No.1 oil outlet 5 and No. five oil outlets 9 pass through
Pipeline is fixedly linked with No.1 oil inlet 2, and No. two oil outlets 6 and No. four oil outlets 8 pass through pipeline and No. two oil inlets 3
It is fixedly linked, No. three oil outlets 7 and No. six oil outlets 10 are fixedly linked by pipeline with No. three oil inlets 4.
Wherein, corresponding mold is manufactured according to the runner that principle designs valve block 1, cast, casting carries out simple process
Afterwards, it then is machined.
In the present embodiment as illustrated in fig. 1 and 2, it realizes modularization, saves material and time, and improve production efficiency.
Wherein, hole is processed according to principle mandates, it is necessary to assure the valve block 1 processed meets the dimensional discrepancy requirement of drawing,
More to guarantee the accurate of 1 relative position of valve block, just can guarantee that 1 function of valve block is good in this way.
In the present embodiment as illustrated in fig. 1 and 2, it can effectively ensure that the accurate of 1 relative position of valve block, just can guarantee valve block in this way
1 function is good.
Wherein, this valve block 1 is using spheroidal graphite cast-iron, and this valve block 1 is the casting of monoblock type.
In the present embodiment as shown in figure and 2, by this using spheroidal graphite cast-iron, so physical property is more outstanding, no
The deformation of valve block 1 can occur and certain high-pressure situations can be subjected to, thus expand the scope of application, monoblock type cast body
Product, inner flow passage roomy many smaller than generally cutting plug in vehicle valve block outer dimension, resistance and damage when pressure oil liquid being made to flow through valve block 1
Mistake also becomes smaller.
Wherein, valve block 1 is using fixed grinding tool, and is cast in a modular manner.
In the present embodiment as illustrated in fig. 1 and 2, material and time are saved, the valve group that valve block 1 can be made and formed with valve block 1
Performance is more stable, improves production efficiency, has accomplished environment economizing type.
The present invention is that one kind cuts slotting vehicle hydraulic system monoblock type valve block, when work, cuts plug in vehicle referring to the drawing present invention and controls
Hydraulic monoblock type valve block is cast by spheroidal graphite cast-iron, after over mechanical processing and surface treatment, becomes this drawing apperance.It is first
Corresponding mold is first manufactured according to the runner that principle designs valve block, is cast, after casting carries out simple process, then carries out machinery
Processing processes hole according to principle mandates, it is necessary to assure the valve block processed meets the dimensional discrepancy requirement of drawing, more to guarantee valve
Block relative position it is accurate, just can guarantee that valve block function is good in this way.Secondly, this valve block is using spheroidal graphite cast-iron, so object
Rationality can be more outstanding, and valve block deformation will not occur and can be subjected to certain high-pressure situations, thus obtain the scope of application
It expands.Then, since this valve block is monoblock type, so volume ratio generally cuts plug in vehicle valve block outer dimension small, inside stream road width
Big many, resistance and loss when pressure oil liquid being made to flow through valve block also become smaller；Finally, due to be fixed grinding tool, so can be real
Existing modularization saves material and time, can make valve block and more stable with the valve group performance of valve block composition, improve production effect
Rate has accomplished environment economizing type.
