At present, the connection of >=80mm specification inner liner stainless steel compound pipeline complex pipelines is general by the way of groove clamping hoop connection.This connection side
Formula, it is safe and reliable, and it is simple to construct, and construction cost is low.However, inner liner stainless steel compound pipeline complex pipeline is a kind of new clad steel
Pipe.Directly its end face cannot be prevented using the connected mode of traditional groove clamping hoop to be contacted with pumped (conveying) medium water.Its end face with it is defeated
After sending WATER AS FLOW MEDIUM to contact, end face causes corrosion, and pollution is drunk and uses water, so as to cause the sanitary condition of drinking water unqualified, meanwhile,
Corrosion can cause leakage accident, greatly shorten the service life of inner liner stainless steel compound pipeline complex pipeline.
Utility model content
, in order to solve during composite steel tube connection in the prior art, steel pipe end surface is in water so that steel for the utility model
Pipe galvanic corrosion, a kind of technical barrier for cause polluted water, pipeline leak, shortening pipeline service life, there is provided clad steel
Full-shield dual-sealing ring is used in pipe connection.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
Full-shield dual-sealing ring, including support frame, interior sealing body and external seal body are used in a kind of composite steel tube connection,
The interior sealing body and external seal body by integral forming, the support frame are fixedly connected with the inwall of the interior sealing body；It is described
Interior sealing body include insertion the composite steel tube mouth of pipe in inner sealing surface and with the integrally formed end face seal face of inner sealing surface, it is described
The quantity of inner sealing surface is 2, is symmetricly set on the both sides in the end face seal face；It is compound that the external seal body is provided with receiving
The draw-in groove of steel tube end part, the external seal body 3 includes the external seal face 31 for sealing composite steel tube outer wall, the external seal face
Quantity be 2, be symmetricly set on the both sides in the end face seal face.
Angle in the inner sealing surface and the interior sealing body between wall is 2-45 degree.
Angle in the external seal face and the external seal body between wall is 2-45 degree.
The outer wall of the support frame is provided with integrally formed connection ring, the support frame by connection ring with it is described
Interior sealing body is fixedly linked.
The material of the interior sealing body and external seal body includes food-grade rubber.
The material of the support frame includes plastics or stainless steel.
The beneficial effects of the utility model：The utility model provides a kind of composite steel tube connection full-shield double containment and seals
Circle, by inner sealing surface, end face seal face and external seal face, realizes triple seal when composite steel tube groove clamping hoop is connected, more
The defect of structure is mended, it is ensured that the fluid in pipe only contacts the stainless steel layer of composite steel tube internal layer without contact composite steel tube
End face, at the same external seal face be further ensured that after clamp connection will not seepage, also ensure that external agency will not penetrate into pipe end,
So as to while steel pipe service life is extended, substantially increase transfer efficiency, ensure that delivery safety, and then guarantee water
Sanitary index.Meanwhile, the utility model is easy for installation when installing and using, and easily reaches installation requirement, should with wide
Use prospect.
