Abstract
The utility model provides a threaded connection's flange formula meter buret section belongs to the measuring equipment field, including following structure: central authorities are equipped with the flange of screw hole, both ends all are equipped with the pipeline section of external screw thread, the screw hole of flange and the external screw thread looks adaptation at pipeline section both ends, the flange is a forging formula flange, the pipeline section is a forging formula pipeline section, the screw thread of flange and the screw thread at pipeline section both ends are the sealed screw thread of tubular. Owing to become two parts with flange and pipeline section split and forge, both can reduce the requirement of forging the mould, reduce mould spoilage and manufacturing cost, avoided flange and pipeline section combination department to produce the forging crack, can avoid casting defects such as a series of blowholes of bringing, gas pocket, crackle again simultaneously.
Description
Technical field
The utility model relates to metering equipment field, refers to a kind of flange-type metering pipeline section be threaded connection especially.
Background technique
The processing method of existing flange-type metering pipeline section can be divided into casting and integral type to forge two kinds of modes substantially.
The blank shape size of founding type is accurate, and amount of finish is little, and cost is low, but the defect such as casting can exist sand holes, pore, crackle, be mingled with, cast-internal flow of tissue line style is also poor, and individual difference alienation is larger, global consistency is poor, easily causes sand holes to leak, bodies splittable in using process.
Compare casting forging mode streamlined good, organize dense, mechanical property is better than cast flange.But during forging, because flange bore is comparatively large, pipeline section bore is relatively little, easily causes flange and pipeline section junction to produce forge slight crack at forging process, and when pumping mode easy damaged mould, make die life lower.
Therefore adopt integrated type forging to require higher to mould, processing technology requires high, and die cost is larger.
Model utility content
The utility model proposes a kind of flange-type metering pipeline section be threaded, by carrying out the mode of welding after being threaded with the joining place tubular sealed of pipeline section at flange, being tightened with pipeline section by flange again, decreasing the requirement of forging mould, reducing cost.
The technical solution of the utility model is achieved in that
The flange-type metering pipeline section be threaded, comprises following structure:
Central authorities are provided with the flange of screw thread hole;
Two ends are equipped with externally threaded pipeline section;
The screw thread hole of described flange and the outside thread at pipeline section two ends suitable.
In technique scheme, described flange is forging formula flange.
In technique scheme, described pipeline section is forging formula pipeline section.
In technique scheme, the screw thread of described flange and the screw thread at pipeline section two ends are tubular sealed screw thread.
It will be understood by those skilled in the art that after flange and pipeline section are threaded, process of can welding junction surface and sandblast.
It will be appreciated by those skilled in the art that, technique scheme is forged due to flange and pipeline section are split into two-part, both the requirement to forging mould be can reduce, burn failure rate and cost of production reduced, avoid flange and pipeline section junction to produce and forge slight crack, can avoid again casting the defect such as a series of sand holes, pore, crackle brought simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the flange-type metering pipeline section that the utility model is threaded;
Fig. 2 is structural representation after the assembling of Fig. 1 each several part;
In figure: 1-flange; 2-pipeline section; 3-flange and pipeline section junction surface.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 and 2, the flange-type metering pipeline section be threaded of the present utility model, comprises following structure:
Central authorities are provided with the flange 1 of screw thread hole;
Two ends are equipped with externally threaded pipeline section 2;
The screw thread hole of described flange 1 and the outside thread at pipeline section 2 two ends suitable.
In technique scheme, described flange is forging formula flange 1.
In technique scheme, described pipeline section is forging formula pipeline section 2.
In technique scheme, the screw thread of described flange 1 and the screw thread at pipeline section 2 two ends are tubular sealed screw thread.
It will be understood by those skilled in the art that after two flanges and a pipeline section are threaded, can flange be welded with pipeline section junction surface 3 and be sandblasted and process.
It will be appreciated by those skilled in the art that, technique scheme is forged due to flange 1 and pipeline section 2 are split into two-part, both the requirement to forging mould be can reduce, burn failure rate and cost of production reduced, avoid flange and pipeline section junction to produce and forge slight crack, can avoid again casting the defect such as a series of sand holes, pore, crackle brought simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
