At present, also there is fittings body and metal coil pipe soldered holds corrosion-prone problem, but and in actual use, the soldered seriously corroded of fittings body and metal coil pipe, is therefore badly in need of the etch-proof problem of soldered solving fittings body and metal coil pipe.
Summary of the invention
The utility model, for the soldered seriously corroded shortcoming of prior art middle joint body and water tank, provides the etch-proof high-pressure pipe connector of a kind of weld seam preventing the soldered of fittings body and water tank from corroding.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The etch-proof high-pressure pipe connector of weld seam, comprises metal coil pipe and fittings body, and the end penetrator body of metal coil pipe is also welded on fittings body end, and the other end of fittings body is provided with nut, is provided with seal ring between nut and metal coil pipe.By nut and fittings body and metal coil pipe with it between be provided with seal ring, fluid is effectively prevented to penetrate into the weld seam of fittings body internal corrosion fittings body and metal coil pipe by the gap between nut and metal coil pipe, thus affect the stability of device, avoid the potential safety hazard that weld corrosion causes.
As preferably, the both sides of seal ring are provided with circular cone, are equipped with the conical bore coordinated with circular cone in nut and fittings body.By arranging circular cone, when nut and fittings body assemble, applying pressure by nut to the conical surface, the inner tight of seal ring being fitted, enhances the sealability of seal ring.
As preferably, fittings body is provided with step First terrace and determines the tack welding circle of welding position, the setting of tack welding circle improves the accuracy of device welding position, eliminate the step that welding position is measured, facilitate the installation of device, by coordinating of First terrace and flanging bore inside, the weld seam blocking water butt joint body and flanging bore in water tank causes corrosion, also facilitate before welding and fittings body is arranged in flanging bore accurately, ensure stability during welding, improve welding precision, and this structure easily realizes machine weldering, keeps away the instability of manual welding.
As preferably, also comprise pipe joint, pipe joint one end is threaded with fittings body, and fittings body is located at the inside of pipe joint, and pipe joint is provided with second step face, and First terrace end coordinates with end, second step face welds.Fittings body is fixedly connected with by internal and external threads with pipe joint by fittings body with after metal Coil welding, and by the welding reinforced pipe joint of step surface and the stability be connected between fittings body and intensity.
As preferably, in fittings body and pipe joint, be equipped with the through hole coordinated with metal coil pipe.By coordinating of metal coil pipe and through hole, decrease metal coil pipe and the direct gap of through hole, ensure that the sealing of device, prevent the infiltration butt welded seam of large quantity of fluid from causing corrosion.
The utility model is owing to have employed above technological scheme, there is significant technique effect: be connected with joint screw thread by the nut at water tank, and seal ring is set between nut and fittings body, the weld seam completely cut off between water butt joint body in water tank and metal coil pipe causes corrosion, extend the working life of device, structure is simple, saves the manufacture cost of product, assembles more convenient.
