Abstract
The utility model discloses a flange connection surface seal device, relates to a pipeline seal device, and aims to improve the flange seal performance between pipelines. The flange connection surface seal device includes a left flange and a right flange, as well as an annular seal gasket arranged between the two flanges, wherein the flange surfaces or the gasket surfaces wherein the two flanges and the annular seal gasket are contacted are coated with seal glue layers, and the two flanges and the a annular seal gasket are connected and fastened together through bolts. On the basis of the present seal flange, the seal glue is additionally applied to the connected surfaces of the flanges and the seal gasket, so that hard seal and soft seal are combined to improve the flange seal performance, the adverse effect caused by loose flange seal can be effectively avoided, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of pipeline sealing device, is specifically related to a kind of flange junction surface seal arrangement.
Background technique
At present, in chemical production field, especially transport, produce when having corrosive product,, can cause harm in various degree such as equipment, pipeline, ground in long-term transportation, the production process owing to itself have extremely strong corrosivity.When aggressive product is carried, sealing between the pipeline is an emphasis, it also is a difficult point, if poor sealing can directly cause exosmose, accident such as leakage, so not only can etching apparatus, cause the loss in the production, and some have volatile aggressive product and can cause also that acid mist fills the air in the Production Regional, pollute environment, staff's physical and mental health are produced have a strong impact on.
Summary of the invention
The purpose of this utility model is in order to improve the sealing of flange between the pipeline, and a kind of flange junction surface seal arrangement is provided.
The utility model is achieved through the following technical solutions:
Flange junction surface seal arrangement, two flanges and be arranged on two ring packing pads between the flange about comprising, scribble sealant layer on wherein said two flanges and contacted flanged surface of ring packing pad or the pad face, described two flanges are connected by bolt with the ring packing pad and tighten together.
Described sealant layer is 1596 sealant layers, this kind sealer function admirable, and viscosity is low, is suitable for the combination seal of component such as water pump, valve.
Between described two flanges and the ring packing pad is coaxial setting, has guaranteed the unobstructed of sealing effect and pipeline to a certain extent.
During use, at first should the removing surface of flange and ring packing pad is clean, impurity such as greasy dirt, water must not be arranged, reveal to avoid when being coated with sealer, causing local starved; Then the ring packing pad is interposed between two flanges, and they are coaxial setting; Then on two flanges and contacted flanged surface of ring packing pad or pad face, smear one deck sealer, with this further sealing effect of optimizing between them; At last two flanges are connected by bolt with the ring packing pad and tighten together; After mutually combining by hard sealing and soft seal like this, the sealing effect of this device has obtained further raising.
The utility model is on existing sealing flange basis, on the junction surface of flange and gasket seal, increase and be coated with a kind of sealer, realize mutually combining of hard sealing and soft seal with this, thereby improve the sealing of flange, can effectively avoid because of the not tight harmful effect that causes of flange seal, simple in structure, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-flange, 2-ring packing pad, 3-bolt, 4-sealant layer.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, flange junction surface seal arrangement, two flanges 1 and be arranged on two ring packing pads 2 between the flange 1 about comprising, scribble sealant layer 4 on wherein said two flanges 1 and ring packing pad 2 contacted flanged surfaces or the pad face, described two flanges 1 are connected by bolt 3 with ring packing pad 2 and tighten together.
It is more that sealant layer 4 can be chosen kind, and in this embodiment, what sealant layer 4 was selected for use is 1596 sealant layers.Between two flanges 1 and the ring packing pad 2 is coaxial setting, has guaranteed the leakproofness of sealing.
Claims (2)
