Abstract
A groove-type flange comprises a flange body, a through hole and bolt holes, wherein, the through hole is used for connecting a pipeline and formed in the center of the flange body, and the bolt holes are uniformly formed near the circumference of the flange body. The flange is characterized in that one groove capable of reducing the weight of the flange body is formed between each two bolt holes on the flange body; and a strengthening rib is formed at the line connecting the circle center of each bolt hole and the central circle center of the flange. In the utility model, partial of the stressless part of the flange body is dug out, and the flange is processed according to the connecting stress principles of flange. With the original sealing effect ensured, the flange provided by the utility model is more convenient and simpler when being mounted, has light weight and reduces material by about 30%, thereby reducing cost and enabling the assembly to be simpler and more labor saving.
Description
(1), technical field
The utility model relates to a kind of liquid, steam pipe road flange connecting dish designing technique such as tap water of being used for, specifically a kind of groove type flange plate, and it is applicable to band tooth (internal thread) flange plate.
(2), background technique
The conventional flange dish of band tooth (band internal thread) all is by monoblock steel or other metal solid shape plate bodys at present; cause Heavy Weight; material is many; the cost height; because Heavy Weight; to some pipelines that needs unsettled connection to be provided with, operation inconvenience is time-consuming painstakingly when connecting with bolt; because of Heavy Weight; pipeline to those unsettled settings also needs to increase fixed support, if working environment is relatively poor, Shan, space is little;, bolt do not reach sealing effect because being difficult for tightening through regular meeting; and operation is difficulty very; time-consuming, generally in use for some time, pipeline is affected by environment very easily damaged or get rusty for various reasons; need repairing or change rubber sheet gasketing; in operation, extremely difficult disassembling, assembling and replacing is made troubles to maintenance work.To sum up these, people are badly in need of that some are few, in light weight with material, cost is low, install and use more conveniently, and the manufacturing technology of the easier flange fixed tray of repair and replacement occurs.
(3), model utility content
Order of the present utility model is to design a kind of fewly with material, and weight is lighter, a kind of more easily groove type flange plate of installation and maintenance.
The utility model is to adopt following technological scheme to realize: it is to improve to form on the technical foundation of existing flange plate, it still comprises the dish body, offer the through hole (through hole has internal thread) that connecting tube is used at the center of flange plate body, near the uniform bolt hole of flange plate body circumference that is opened in, it is characterized in that offering between per two bolts hole of flange plate body (dig and establish) has the groove (or claiming pit) that can alleviate this body weight of flange plate, is formed with stiffening rib at the line of centres place in each the bolt hole center of circle and the flange plate central authorities center of circle.Use the utility model flange plate identical: when connecting two pipelines with the use operating method of conventional art flange plate, earlier will every pipeline connect (flange plate of being with tooth is with being threaded) with separately flange plate, install flange seal jam (rubber sheet gasketing) afterwards, two flange plate are aimed at bolts hole, insert the bolt and nut connection that screws up with a wrench afterwards again.Stressed principle after the utility model connects according to flange plate is dug up the no force part part of flange plate disk body, allow force bearing point be positioned on the reinforced rib on each bolt hole center's line and on other auxiliary ribs, when using the utility model, because the flange plate disk body is carried out part hollows out the formation pit, so just alleviated the weight of disk body greatly, not only do not influence its stressed effect, also have when unsettled installation connecting tube, its gravity is stressed light, install lightly, reduced labor intensity, install lighter, comfortable, simple.The utility model can be saved manufactured materials about 30%, has saved cost greatly, alleviates workload, increases work efficiency.The utility model is in light weight in a word, and is simple to operate, can seal better, and to increasing work efficiency, it is very favourable to reduce cost of material.
(4), description of drawings
Fig. 1 is unitary construction schematic representation of the present utility model (for a kind of tectonic maps with the tooth flange plate);
Fig. 2 be Figure 1A-A to sectional view (right pseudosection).
(5), embodiment
Can find out that with reference to accompanying drawing unitary construction of the present utility model comprises: 1～dish body, through hole (through hole has internal thread) is installed at 2～flange plate center, 3～bolt hole, 4～groove (or claiming pit).5～be positioned at the stiffening rib at bolt hole center line place, 6～be positioned at the auxiliary reinforced rib at each groove middle part, 7～flange plate circumferential part (outer edge), 8～flange plate are used to connect waits the sidepiece taken over.
The utility model structure is the same with the conventional flange dish, still comprise flange plate body 1, offer the through hole 2 (band internal thread) that connecting tube is used at the center of flange plate body, near the uniform bolt hole 3 of flange plate body circumference that is opened in, offering (dig and establish) between per two bolts hole of flange plate body has the groove (pit) 4 that can alleviate this body weight of flange plate, is formed with stiffening rib 5 at the line of centres place in each the bolt hole center of circle and the flange plate central authorities center of circle.
But with reference to accompanying drawing as can be known, the utility model concrete make to add also have following technical characteristics man-hour:
One, also designs at described each groove middle part (i.e. middle part between per two bolts hole) auxiliary reinforced rib 6 is arranged, should assist the inner end of reinforced rib and the central through bore outer rim of flange plate body to join, the outer circumference portion 7 (outer edge) of its outer end and flange plate body is joined.
Two, described groove (or pit) the 4th, design is positioned at a sidepiece 8 that is connected with road to be taken over of flange plate body 1.
Of the present utility modelly do not state part identical with prior art.
Claims (3)
1, a kind of groove type flange plate, it comprises dish body (1), offer the through hole (2) that connecting tube is used at the center of flange plate body (1), near the uniform bolt hole (3) of flange plate body circumference that is opened in, it is characterized in that between per two bolts hole of flange plate body, offering the groove (4) that can alleviate this body weight of flange plate, be formed with stiffening rib (5) at the line of centres place in each the bolt hole center of circle and the flange plate central authorities center of circle.
2, according to the described groove type flange plate of claim 1, it is characterized in that at described each groove middle part also design has auxiliary reinforced rib (6), the central through bore outer rim of the inner end of this reinforced rib and flange plate body is joined, and the outer circumference portion (7) of its outer end and flange plate body is joined.
3,, it is characterized in that described groove (4) is the sidepiece (8) that is connected with road to be taken over that design is positioned at flange plate body (1) according to claim 1 or 2 described groove type flange plate.
