Description
Technical field
The present invention relates to a kind of valve body location structure, this structure drops in specifically a kind of four point positioning.
Background technology
As resource is reduced, the rise of steel raw material, also when the river rises the boat goes up for the cost of steel products, but extravagent price
But the competitiveness of product in market is limited, hinders and promotes, the economic activity of enterprise is affected.Therefore material cost is reduced,
Again competitiveness of winning the market is the extremely urgent thing of enterprise.Existing valve body middle chamber machined surface internal diameter is bigger, the material of consumption
Material is more, adds the man-hour of expenditure of time also just a lot.And during rough-cast, in addition to allowance is met, also
Consider deformation of the casting pattern under molten steel impact, therefore, casting surplus is bigger, even more so especially for wooden model, and one
As processing capacity be both greater than 5mm.Mach internal diameter is bigger during design, then the metal needed is more, wastes just more serious.
The content of the invention
It is an object of the invention to provide a kind of four point positioning to drop this structure, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：
This structure drops in a kind of four point positioning, including valve body, support stuffing box, four point positioning structure, middle mouth machined surface and in
The non-processing face of mouth, the valve body is interior to be provided with the face of cylinder, and four point positioning structure, the four point positioning knot are provided with the downside of the face of cylinder
Structure upper surface is middle mouth machined surface, and the four point positioning structure upper surface periphery is provided with the non-processing face of middle mouth, and the middle mouth is non-to be added
The middle mouth machined surface of work face and four point positioning structure upper surface is in same plane.
As the further scheme of the present invention：Support stuffing box is provided with the valve body, the support stuffing box is arranged on
On the upside of four point positioning structure.
As further scheme of the invention：The four point positioning structure is four symmetrical projection fritters.
As further scheme of the invention：The thickness of the four point positioning structural protrusions is equal or slightly larger than more than casting
Amount.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is simple in construction, by four point positioning structure, keeps away
Exempt from that lumen machined surface internal diameter is bigger, and the material of consumption is more, the problems such as adding the man-hour of expenditure of time long, reduce allowance,
Man-hour is reduced, solves the problems, such as that valve is excessive using raw material, realizes valve locally this elementary object of drop.
Brief description of the drawings
Fig. 1 is the structural representation that this structure drops in four point positioning.
Fig. 2 is the cross section structure schematic diagram that this structure drops in four point positioning.
Fig. 3 is the structural representation that 4 structures in this structure drop in four point positioning.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1~3, in the embodiment of the present invention, this structure, including valve body 1, support stuffing box drop in a kind of four point positioning
2nd, four point positioning structure 3, middle mouth machined surface 4 and the non-processing face 5 of middle mouth, the valve body 1 is interior to be provided with the face of cylinder 31, the face of cylinder
31 downsides are provided with four point positioning structure 3, and the four point positioning structure 3 is four symmetrical projection fritters, the four point positioning knot
The thickness of the projection of structure 3, which is equal or slightly larger than, casts surplus, as long as machined surface 4 is worked into size during processing, due to internal diameter
Small, the machining period of consuming is also relative to be lacked, and support stuffing box 2 is provided with the valve body 1, and the support stuffing box 2 is arranged on
The upside of four point positioning structure 3, the upper surface of four point positioning structure 3 are middle mouth machined surface 4, the upper end of four point positioning structure 3
Face periphery is provided with the non-processing face 5 of middle mouth, and the middle mouth machined surface 4 in the middle non-processing face 5 of mouth and the upper surface of four point positioning structure 3 exists
Same plane, in casting in the affix of mouth machined surface 4 amount of metal compared to being not that coplanar valve body will lack, can effectively drop
Low cost.
The present invention in valve body 1 by, using four point positioning structure 3, avoiding lumen machined surface internal diameter bigger, the material of consumption
It is more, the problems such as adding the man-hour of expenditure of time long, reduce allowance, reduce man-hour, while reduce cost.
The internal diameter of mouth machined surface 4 is bigger in the present invention, and the material of consumption is more, adds the man-hour of expenditure of time also just a lot.
And during rough-cast, in addition to allowance is met, it is also contemplated that deformation of the casting pattern under molten steel impact, because
This, casting surplus is bigger, and even more so especially for wooden model, general processing capacity is both greater than 5mm.It is mach during design
Internal diameter is bigger, then the metal needed is more.Waste just more serious.Therefore it is very that reduced inner diameter, which reduces preprocessing amount of metal,
Practicable method.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
