Abstract
The utility model provides a sealing washer is used in compound steel pipes connection, including support chassis and seal, the seal including insert the intraoral inside seal face of compound steel pipes pipe and with inside seal face integrated into one piece's end face seal face, the inside seal face is 2, and the symmetry sets up the both sides of end face seal face. Solved when compound steel pipes connects among the prior art, the steel pipe terminal surface exposes in aqueous for steel pipe galvanic corrosion leads to pollute water, pipeline to leak, shorten pipeline life's technological problem.
Description
Technical field
The utility model relates to a kind of sealing-ring, specifically, it relates to a kind of composite steel tube connection sealing-ring.
Background technology
Drinking by the quality of water to improve, prevent some the harmful elements caused due to the inwall of water long-term corrosion metal tube from entering and drink with water, be detrimental to health, inner liner stainless steel water delivery pipeline is widely used. At present, the mode connecting general employing groove clamping hoop connection of >=80mm specification inner liner stainless steel compound pipeline complex pipeline. This kind of mode of connection, safe and reliable, and it is simple to construct, and construction cost is low. But, inner liner stainless steel compound pipeline complex pipeline is a kind of novel composite steel tube. Directly adopt the mode of connection of traditional groove clamping hoop cannot stop its end face to contact with delivery medium water. After its end face contacts with delivery medium water, end face causes corrosion, pollutes and drinks with water, thus the sanitary condition causing tap water is defective, and meanwhile, corrosion can cause leakage accident, greatly shortens the work-ing life of inner liner stainless steel compound pipeline complex pipeline.
Practical novel content
When the utility model is in order to solve composite steel tube connection in prior art, steel pipe end face is exposed in water, make steel pipe galvanic corrosion, cause the technical barrier that polluted water, pipeline leak, shorten pipeline work-ing life, it provides a kind of composite steel tube connection sealing-ring.
For solving the problems of the technologies described above, the utility model provides a kind of composite steel tube connection sealing-ring, comprise support frame and sealing member, the inwall of described support frame and described sealing member is fixedly linked, described sealing member comprises the inner sealing surface in the insertion composite steel tube mouth of pipe and mechanical seal face integrated with inner sealing surface, described inner sealing surface is 2, is symmetricly set on the both sides in described mechanical seal face.
Further, angle between described inner sealing surface and described sealing member inwall is 2-45 degree.
Further, angle between described inner sealing surface and described sealing member inwall is 30 degree.
Further, described inner sealing surface is plane or curved surface.
Further, described inner sealing surface is provided with sealing thread.
Further, the outer wall of described support frame is provided with shack, and described support frame is fixedly connected with described sealing member by shack.
Further, the outer wall of described support frame is provided with groove ring, and the inwall of described sealing member is provided with protruding ring, and described support frame and described sealing member are mutually blocked by described protruding ring and described groove ring and be connected together in succession.
Further, the material of described support frame is plastics or stainless steel.
Further, described sealing member is food grade rubber material.
The Advantageous Effects that the utility model reaches: the utility model provides a kind of composite steel tube connection sealing-ring, by inner sealing surface and mechanical seal face, achieve double seal when composite steel tube groove clamping hoop connects, compensate for the defect of structure, ensure that the stainless steel layer of the contact composite steel tube internal layer of the fluid in pipe and do not contact the end face of composite steel tube, thus while extending steel pipe work-ing life, substantially increase transport efficiency, ensure that delivery safety, and then the sanitary index of guarantee water. Meanwhile, the utility model is when installing and using, easy for installation, it is easy to reach installation requirement, has broad application prospects.
