Abstract
The utility model provides a welding-free insulation connector and relates to a welding-free insulation connector suitable for a small-bore pipe line. The welding-free insulation connector comprises a left flange, a hook circle, a right flange, an O-shaped sealing ring, an insulation sealing member and a sealing filler. The left flange is connected with the hook circle through threads or buckles movably. The welding-free insulation connector does not need a welding process, is simple and easy to assemble, and avoids the problem that the welding-free insulation connector loses effectiveness or shortens service life due to the fact that the sealing ring is damaged due to welding in a manufacturing process. The welding-free insulation connector is particularly suitable for pipe lines with bore below DN200, and practical environment pressure range is below PN 1.6MPa.
Description
Technical field
The utility model relates to a kind of insulating joint, and what especially be applicable to small pipe-line exempts from the welding insulation joint.
Background technique
Insulating joint is requisite important pressure elements in the steel pipe cathodic protection system, and it is widely used in the cathodic protection system of steel pipe.Its effect is mainly: metallic conduit is realized electrical insulation before and after making it, is equivalent to the purpose that pipeline satisfies fed sheet of a media simultaneously.Conventional insulating joint structure is as shown in Figure 1: by left flange 1, right flange 2, collude circle 3, O RunddichtringO 4, insulating sealer 5, stuffing box packing 6 and forms, must weld together and could use colluding circle 3 and left flange 1 during assembling.During welding, the O RunddichtringO 4 that too high temperature is easy to cause rubber material to be made damages, thereby loses seal action, influences working life.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of ease of assembly, long service life exempt from the welding insulation joint.
The purpose of this utility model is achieved through the following technical solutions: exempt from the welding insulation joint, comprise left flange, Gou Quan, right flange, O RunddichtringO, insulating sealer, stuffing box packing, it is characterized in that: left flange with collude circle and flexibly connect.
Described left flange is respectively equipped with screw thread with colluding on the circle, the two is by being threaded.
Described left flange is respectively equipped with outer buckle, interior buckle with colluding on the circle, the two connects by buckle.
The beneficial effects of the utility model: the utility model adopts said structure, left flange with collude circle and flexibly connect by screw thread or buckle mode, need not to weld link, simple and convenient assembly is easily gone.Solved because welding causes seal ring and damaged, and working life low problem.Be particularly useful for the following pipeline of bore DN50, practical external pressure scope: below the PN1.6MPa.
