Abstract
A cast iron flange plate is composed of a tubular flange base body (1) and a disc-shaped flange face (2) which are fixedly connected together, the axes of the flange base body and the flange face coincide, and pipes inside the flange base body and the flange face are identical in internal diameter. The cast iron flange plate is characterized in that the requirement for internal diameter size and tolerance of the flange base body (1) in the cast iron flange plate is fai65+/-0.005mm, and the requirement for external diameter is fai95mm. The requirement for external diameter of the flange face (2) is fai210mm. Four to eight connecting holes (3) parallel to the axis of a pipe cavity inside the flange plate are evenly arranged on the flange face (2) outside the external diameter of the flange base body (1) along the peripheral direction. Compared with the prior art, the cast iron flange plate is simple in design and excellent in performance and has predictable and huge economic value and social value.
Description
Technical field
The present invention relates to flange plate structure design and applied technical field, a kind of cast iron flange is provided especially.
Background technique
In the prior art, flange plate is varied.For satisfying actual demand, under various concrete backgrounds, require to use various flange plate.For mating certain special usage requirement, people expect to obtain that a kind of specific aim is strong, the better flange plate of technique effect.
Summary of the invention
The purpose of this invention is to provide the good cast iron flange of a kind of technique effect.
The invention provides cast iron flange, it is made of the flange matrix (1) of the tubulose that is fixed together and the flanged surface 2 of plate-like, and the bore of above-mentioned two segment axis coincidence and inside is identical; It is characterized in that:
Flange matrix 1 internal diameter size and tolerance in the described cast iron flange are Φ 65 ± 0.005mm, and outside dimension requires to be Φ 95mm;
The outside dimension of described flanged surface 2 parts requires to be Φ 210mm; On the flanged surface 2 of flange matrix 1 external diameter outside, be evenly arranged in the circumferential direction of the circle 4 ~ 8 attachment holes 3 parallel with flange plate interior lumen axial direction.
Described cast iron flange preferably requires as follows: have apart from the location arrangements of axis 75mm to be evenly arranged in the circumferential direction of the circle 4 attachment holes 3 on the flanged surface 2 of flange matrix 1 external diameter outside, aperture size is Φ 15mm.
Described cast iron flange is 90mm along the total height of flange plate interior lumen axial direction, and wherein, the axial thickness of flanged surface 2 parts is 18 ± 0.2mm.
The interior lumen proximal end of described cast iron flange also is provided with 2 * 45 ° chamfering structure.
In terms of existing technologies, flange plate simplicity of design of the present invention, function admirable; Select all cast iron qualities preferably of casting and cutting ability, both guaranteed preferably metal cutting performance, guaranteed reliability and the wear resistance of its finished product.It has foreseeable comparatively huge economic value and social value.It can mate the special usage requirement of certain equipment well, and specific aim is strong, technique effect is good.
