Abstract
The invention provides a flange cover connection structure with a pre-coated sealing layer. The flange cover connection structure comprises a flange cover main body and a flange main body; the flange cover main body is in an annular shape; a sealing surface edge is arranged on the circumference of an end opening of the connection end of the flange cover main body; a sealing glue layer is arranged in an area inside the sealing surface edge; the edge of the sealing glue layer is in contact with the sealing surface edge; an annular lug boss is arranged on a butt-joint end face of the flange main body corresponding to the sealing surface edge of the flange cover main body; an external diameter of the annular lug boss is equal to an internal diameter of the sealing surface edge; and the height of the annular lug boss is a half of the height of the sealing surface edge. The flange cover connection structure has the beneficial effects as follows: good sealing effect can be achieved through the sealing surface edge arranged at the connection end of the flange cover main body, the sealing glue layer arranged at the inner side of the sealing surface edge, and the matched connection with the annular lug boss of the flange main body.
Description
Technical field
The present invention relates to a kind of blind flange linkage structure with the precoating sealing layer.
Background technique
At present, existing flanged connecting structure is that one deck seal ring or sealing gasket are set in the connecting port of two blind flanges when sealing, seals through seal ring or sealing gasket.In the process of operation, the center that seal ring or sealing gasket depart from flange occurs, cause the sealing effect of seal ring or sealing gasket not good through regular meeting.
To above-mentioned improved design be, on flange port, scribble one deck sealer coating, close lid after glue to be sealed dries again and connect sealing.This mode need be waited for the long time, and the uniformity coefficient that sealer is smeared can not carry out better controlled, the problem that also can bring sealing effect to descend.
The model utility content
The objective of the invention is to overcome the shortcoming of above-mentioned existing technology, a kind of blind flange linkage structure of band precoating sealing layer is provided.
The objective of the invention is to realize through following technological scheme:
A kind of blind flange linkage structure with the precoating sealing layer; Comprise blind flange body and flange body, said blind flange body is ring, is provided with sealing surface limit lip at the circumference of the connecting end port of said blind flange body; The inner zone of lip is provided with one deck sealant layer on said sealing surface limit; The edge of said sealant layer and sealing surface limit lipped joint touch, and the sealing surface limit lip of corresponding said blind flange body is provided with annular boss at the butt joint end face of said flange body; The external diameter of said annular boss equates that with the internal diameter of said sealing surface limit lip the height of said annular boss is the half the of said sealing surface limit bilabial degree.
The invention has the beneficial effects as follows,, be connected, can reach good sealing effect with the annular boss of flange body through sealing surface limit lip and the inboard sealant layer thereof that is provided with at the connecting end of blind flange body.With the height of said annular boss is the half the of said sealing surface limit bilabial degree, and the sealing effect after can guaranteeing to cooperate is unlikely to the sealant layer destructiveness that sealing surface limit lip is inner and compresses, and can play the effect of its inner sealant layer of protection.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural drawing of the blind flange linkage structure of band precoating sealing layer according to the invention.
Embodiment
As shown in Figure 1; The blind flange linkage structure of the described band precoating of embodiment of the invention sealing layer; Comprise blind flange body 1 and flange body 2, said blind flange body 1 is ring, is provided with sealing surface limit lip 3 at the circumference of the connecting end port of said blind flange body; Lip 3 inner zones are provided with one deck sealant layer 4 on said sealing surface limit; The edge of said sealant layer 4 contacts with sealing surface limit lip 3, and the sealing surface limit lip 3 of corresponding said blind flange body 1 is provided with annular boss 5 at the butt joint end face of said flange body 2; The external diameter of said annular boss 5 equates that with the internal diameter of said sealing surface limit lip 3 height of said annular boss 5 is the half the of said sealing surface limit lip 3 height.
The invention has the beneficial effects as follows,, be connected, can reach good sealing effect with the annular boss of flange body through sealing surface limit lip and the inboard sealant layer thereof that is provided with at the connecting end of blind flange body.With the height of said annular boss is the half the of said sealing surface limit bilabial degree, and the sealing effect after can guaranteeing to cooperate is unlikely to the sealant layer destructiveness that sealing surface limit lip is inner and compresses, and can play the effect of its inner sealant layer of protection.
Claims (2)
1. blind flange linkage structure with the precoating sealing layer; Comprise blind flange body and flange body, it is characterized in that said blind flange body is ring; Circumference at the connecting end port of said blind flange body is provided with sealing surface limit lip; The inner zone of lip is provided with one deck sealant layer on said sealing surface limit, and the edge of said sealant layer and sealing surface limit lipped joint touch, the sealing surface limit lip of corresponding said blind flange body; Butt joint end face in said flange body is provided with annular boss, and the external diameter of said annular boss equates with the internal diameter of said sealing surface limit lip.
2. the blind flange linkage structure of band precoating sealing layer as claimed in claim 1 is characterized in that, the height of said annular boss is the half the of said sealing surface limit bilabial degree.
