Abstract
The utility model discloses a flat welding flange with a neck. The flat welding flange with the neck is low and affordable in price and convenient to install, and has corrosion resistance at the same time. According to the technical scheme, the flat welding flange with the neck is characterized by comprising a base plate and a neck table. The neck table is arranged on one side of the base plate. The base plate and the neck table are integrally formed. A flow guiding hole is formed in the central position of the base plate and the central position of the neck table. A plurality of bolt through holes are further formed in the periphery of the base plate. The circle centers of the bolt through holes are evenly distributed on the same circumference by using the center of the base plate as the circle center. The flat welding flange with the neck is characterized by further comprising a sealing bushing ring sleeve. A boss is arranged on one side, opposite to the neck table, of the base plate. The sealing bushing ring sleeve comprises a bottom arranged on the boss, and the neck tightly attached to the inner wall of the flow guiding hole. Due to the sealing bushing ring sleeve, the flange resists corrosion, and sealing of the combination between flanges is ensured at the same time.
Description
Technical field
The utility model relates to a kind of flange technical field, and more particularly, it relates to a kind of hubbed clip-on-welding flange.
Background technique
Flange be make pipe and pipe and and the interconnective part of valve, be connected in pipe end.Perforation on flange, bolt is close to two flanges, between flange, with liner, seal, flange divides (silk connects) flange and welded flange and the cutting ferrule flange that be threaded, it is exactly two pipelines, pipe fitting or equipment that flange connects, first be fixed on separately on a flange plate, between two flange plate, add flange gasket, by bolton together, complete connection, it is the important Placement of pipeline construction that flange connects, and flange connects easy to use, can bear larger pressure, in industrial pipeline, the use that flange connects is very extensive.
The hubbed clip-on-welding flange having at present directly note to be pressed whole flange to form with stainless steel, causes on the high sidely, and because stainless steel hardness is lower, can in the way of transportation, easily collide with, and causes damaging, uneconomical; Also have a hubbed clip-on-welding flange to note to press by the firm material of carbon and form, but due to the firm material of the carbon characteristic that is easily corroded, in the face of weak during various aggressive medium in pipeline, the connection between flange and flange also needs to seal by adding the cushions.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of i.e. cheap material benefit, has corrosion resistance and reduces again flange and connect and also need the link that adds the cushions and seal.
For achieving the above object, the utility model provides following technological scheme: a kind of hubbed clip-on-welding flange, comprise chassis and neck platform, described neck platform is located in a side on described chassis, described chassis and neck platform are one-body molded, described chassis and neck platform center position offer pod apertures, described chassis surrounding also offers several bolt holes, and the center of circle of described bolt hole is uniformly distributed on the same circumference that the center on described chassis is the center of circle, also include Liner Seal Ring cover, relative neck platform one side in described chassis is provided with boss, described Liner Seal Ring cover comprises the bottom being located on described boss, with the neck being close on described pod apertures inwall.
By adopting technique scheme, by Liner Seal Ring cover, arranged and increased the practicability of flange in pipeline using process, the various aggressive mediums in fearing pipeline, also do not need the link sealing by adding the cushions between minimizing flange and flange, reduce operating procedure, cost-saving.
The utility model is preferably set to: the material of described chassis and neck platform is carbon steel, and described Liner Seal Ring cover is stainless steel integrated notes pressure.
By adopting technique scheme, stainless price is more than ten times of the firm price of carbon, carbon is far super stainless steel also aspect hardness just, can also guarantee the damage causing that flange is not reeled in transit when adopting carbon just to process the cost that chassis and neck platform reduce.
This practicality is further set to: described Liner Seal Ring cover end is hollow cylindrical, and described Liner Seal Ring cover bottom is hollow ring.
By adopting technique scheme, Liner Seal Ring cover is close to internal chamber wall and round platform, the easness that reinforcing flange is connected with flange and facilitate pipe fitting insertion flange process, raising operator's efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of hubbed clip-on-welding flange embodiment's of the utility model structural representation.
1-chassis in figure, 2-neck platform, 3-pod apertures, 4-bottom, 5-bolt hole, 6-Liner Seal Ring cover, 7-boss, 8-neck.
Embodiment
With reference to Fig. 1, the embodiment of a kind of hubbed clip-on-welding flange of the utility model is described further.
A kind of hubbed clip-on-welding flange, comprise chassis 1 and neck platform 2, described neck platform 2 is located in a side on described chassis, described chassis 1 and neck platform 2 are one-body molded, described chassis 1 and neck platform 2 center positions offer pod apertures 3, described chassis 1 surrounding also offers several bolt holes 5, and the center of circle of described bolt hole 5 is uniformly distributed on the same circumference that the center on described chassis is the center of circle, it is characterized in that: also include Liner Seal Ring cover 6, relative neck platform 2 one sides in described chassis 1 are provided with boss 7, described Liner Seal Ring cover 6 comprises the bottom 4 being located on described boss 7, with the neck 8 being close on described pod apertures 3 inwalls, the material of described chassis 1 and neck platform 2 is carbon steel, described Liner Seal Ring cover 6 is that stainless steel integrated notes are pressed, described Liner Seal Ring cover end 8 is hollow cylindrical, described Liner Seal Ring cover bottom 4 is hollow ring.。
When flange need to be faced the aggressive medium in pipeline, the end 8 of described Liner Seal Ring cover 6 is stainless steel, has compared with strong corrosion resistant, guarantees the service life of flange, and avoiding medium to leak affects the situation of environment; It is exactly two pipelines, pipe fitting or equipment that flange connects, first be fixed on separately on a flange plate, between two flange plate, add flange gasket, passing through bolt-locking, the bottom 4 of Liner Seal Ring cover 6 has been connected on the boss 7 on described chassis 1, reduces the link that also needs to add flange gasket or grommet pad, improve operator's working efficiency, cost-saving.
A kind of hubbed clip-on-welding flange above the utility model embodiment being provided is described in detail, and for one of ordinary skill in the art, the thought according to the utility model embodiment, all will change in specific embodiments and applications.In sum; this description should not be construed as restriction of the present utility model; other any any variation and modification of doing according to the constructed thought of the utility model and scope of patent protection or be equal to enforcement, is scope of patent protection of the present utility model and contains.
