Abstract
The utility model relates to a flange blind plate, including the blind plate body, a blind plate body terminal surface is equipped with fixed boss, and the outward flange of fixed boss is equipped with the sealing washer, is equipped with sealed recess on the sealing washer, is equipped with the through -hole outer lane between the outward flange of sealing washer outward flange and blind plate body, is equipped with the through -hole on the through -hole outer lane. Compared with the prior art, the utility model has following advantage: overall structure is simple, and the manufacture craft is simple and convenient, has reduced the limitation of connecting, has prolonged life, has also practiced thrift the cost, connects reliably, has increased fastness, leakproofness and the compressive capacity of blind plate.
Description
Technical field
The utility model relates to a kind of blank flange, belongs to blind plate technical field.
Background technique
Blind plate is a kind of part being used for blocking pipe mouth.At present, in the pipeline of industry-by-industry every field, all blind plate has been used.In chemical industry, often can touch some has pollution to environment, and human body is had to the liquid of harm, these Liquid transfer are particularly careful.In the prior art, blind plate is connected with pipeline by means of only bolt, although very simple in operation and dismounting, but when the pressure of the liquid carried is excessive, be easy to cause huge impact to blind plate, make these have pollution to environment, human body is had to the liquid meeting outflow conduit of harm, this will cause imponderable injury to environment and the mankind.Therefore, the soundness of blind plate and sealing very important.
Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of blank flange.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of blank flange, comprise blind plate body, blind plate body one end face is provided with fixing lug boss, the outward edge of fixing lug boss is provided with seal ring, seal ring is provided with sealed groove, is provided with through hole outer ring between the outward edge of seal ring outward edge and blind plate body, and through hole outer ring is provided with through hole.
The related content of technique scheme is explained as follows:
In technique scheme, blind plate body outer wall side is provided with arc and fixes concave surface.
Further technological scheme, the diameter of fixing lug boss outwards diminishes gradually to blind pipe body, and fixing lug boss top is smooth flat.
Preferably, fixing lug boss side surface is provided with boss seal groove.
Preferably, arc fixes concave surface four, is equidistantly located at blind pipe body outer wall side.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Overall structure is simple, and preparation process is easy, reduces the narrow limitation of connection, extends working life, also save cost, connects reliable, adds the soundness of blind plate, sealing and anti-pressure ability.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram.
In above accompanying drawing: 1, blind plate body; 2, fixing lug boss; 3, smooth flat; 4, boss seal groove; 5, seal ring; 6, sealed groove; 7, through hole outer ring; 8, through hole; 9, arc fixes concave surface.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, a kind of blank flange of the present utility model, comprise blind plate body 1, blind plate body 1 one end face is provided with fixing lug boss 2, the diameter of fixing lug boss 2 outwards diminishes gradually to blind pipe body 1, fixing lug boss 2 top is smooth flat 3, fixing lug boss 2 side surface is provided with boss seal groove 4, the outward edge of fixing lug boss 2 is provided with seal ring 5, seal ring 5 is provided with sealed groove 6, through hole outer ring 7 is provided with between the outward edge of seal ring 5 outward edge and blind plate body 1, through hole outer ring 7 is provided with through hole 8, blind plate body 1 outer wall side is provided with arc and fixes concave surface 9, arc fixes concave surface 9 four, equidistantly be located at blind pipe body 1 outer wall side, while reducing cost, also can prevent blind pipe from crossing and smoothly affect using effect, overall structure is simple, preparation process is easy, reduce the narrow limitation of connection, extend working life, also save cost, connect reliable, add the soundness of blind plate, sealing and anti-pressure ability.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
