Abstract

The present invention provides a kind of welded type flange, including some splits, and welding from beginning to end forms flange body successively for the split, and the flange body is in cirque structure, and the flange body is provided with concentric annular groove, some nuts are provided with the annular groove.The beneficial effects of the invention are as follows the production efficiency for effectively improving flange.

Description

Welded type flange
Technical field
The invention belongs to flange technical field, more particularly, to a kind of welded type flange.
Background technology
Flange is the part being connected with each other between pipe and pipe, for the connection between pipe end；Also have and passed in and out used in equipment Flange on mouth, for the connection between two equipment, existing flange is mostly annular overall structure, passes through casting Produced etc. mode, low production efficiency, one kind can solve this problem, improve the welded type flange of production efficiency also Up for further research and development.
The content of the invention
It is an object of the invention to provide a kind of welded type connection simple in construction, simple to operate, can effectively improving production efficiency Flange.
The technical scheme is that：A kind of welded type flange of the present invention, including some splits, the split are first successively Tail welds to form flange body, and the flange body is in cirque structure, and the flange body is provided with concentric ring Connected in star, the annular groove is interior to be provided with some nuts.
Preferably, the flange body is welded by four identical splits.
The present invention has the advantages and positive effects of：Because using above-mentioned technical proposal, the manufacturing of adpting flange is more Add the production efficiency for conveniently, substantially increasing adpting flange.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：
1- flange bodies, 2- splits, 3- annular grooves, 4- nuts.
Embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
【Embodiment 1】
As shown in figure 1, a kind of welded type flange of the present invention, some welding of split 2 form flange body 1, the flange Body 1 is in cirque structure, and the flange body 1 is provided with concentric annular groove 3, set in the annular groove There are some nuts 4.
【Embodiment 2】
The present embodiment is optimized on the basis of embodiment 1, and the flange body 1 is welded by four identical splits 2 Form.
The course of work：
Manufacture the present invention adpting flange when, can first stamped equivalent to a quarter flange body 1 split 2, Then it is attached by welding manner again, is compared to the mode of production of the whole annular adpting flange of casting, significantly Improve operating efficiency.
One embodiment of the present of invention is described in detail above, but the content is only presently preferred embodiments of the present invention, It is not to be regarded as the practical range for limiting the present invention.Any changes and modifications in accordance with the scope of the present application, All should still it belong within the patent covering scope of the present invention.
