Abstract
The utility model relates to a connecting fitting of a bending thread hole, which relates to a connecting fitting, in particular to a connecting fitting used to bending positions among tubes. Most connections among the existing pipe fittings are thread connections, which not only causes troubles on processing and inconvenience but also easily leads to the leakage of liquid or gas inside the pipe fittings because of unclose matching among threads. The connecting fitting of a bend thread hole comprises a connecting tube (1), two ends of the connecting tube (1) respectively and fixedly connected with a flange joint (2) and a flange joint (3). The orientations of connected ends of the two flange joint (2) and flange joint (3) are different, the flange joint (2), the flange joint (3) and the connecting tube (1) are hollow structure and communicated mutually. The connecting tube of the bending thread hole solves the problems of inconvenience and easy leakage among pipe fittings, which can be widely utilized to the connection among pipe fittings.
Description
Technical field: the utility model relates to a kind of link, particularly is used for the link of elbow between pipe fitting.
Background technique: the connection between existing pipe fitting mostly is and is threaded, termination or the link that requires pipe fitting that be threaded all is processed into screw thread, so not only processing trouble, inconvenience, and not tight owing to cooperating between the screw thread, cause the leakage of liquid in pipe or gas easily.
Summary of the invention: the purpose of this utility model is to provide a kind of elbow tapped hole link, good airproof performance not only, and can connect easily.The purpose of this utility model is achieved in that its composition of elbow tapped hole link comprises connecting tube 1, respectively be connected with a flanged joint 2 at the two ends of described connecting tube 1, flanged joint 3, described flanged joint 2, flanged joint 3 connecting end faces are towards difference, flanged joint 2, flanged joint 3 and connecting tube 1 all are hollow structure, and be interconnected, junction surface one side on the described flanged joint 2 has a circular protrusions 4, there is the threaded connection hole 5 through flanged joint 2 at described protruding 4 edge, exterior edge face on flanged joint 2, described flanged joint 3 is provided with groove 6, seal ring 7 is housed in groove 6, the threaded connection hole 8 through flanged joint 3 is arranged at the edge of flanged joint 3 the above seal ring 7.Advantage of the present utility model is: be connected with two connecting end faces towards different flanged joints around connecting tube 1, make link between pipe fitting with flanged joint, avoided the trouble of machining screw on pipe fitting like this, solved and connect elbow especially between the pipe fitting and connect inconvenient problem; Junction surface one side of flanged joint 2 is provided with circular protrusions 4, there is threaded connection hole 5 at edge in projection 4, like this can clamping plate or folder one deck seal ring at projection 4 edge, exterior edge face on flanged joint 3 is provided with groove 6, seal ring 7 is housed in groove 6, the clamping plate at seal ring 7 and protruding 4 edges can guarantee to be connected closely between link and the pipe fitting, have avoided gas or leaked liquid in the pipe.Be provided with a tapped hole 9 in the lower end of connecting tube 1, when pipeline normally uses, the hole tightened, when working undesired or overhauling, be convenient to turn on the bolt removal of contamination, make pipe fitting use convenient, safety with bolt.
Description of drawings: Fig. 1 is a main sectional view of the present utility model, and Fig. 2 is the sectional view of Fig. 1.
Embodiment: present embodiment comprises connecting tube 1, be connected with flanged joint 2, flanged joint 3 respectively at the two ends of connecting tube 1, the connecting end face of flanged joint 2, flanged joint 3 is towards difference, be convenient to the connection between the pipe fitting of different direction like this, flanged joint 2, flanged joint 3 and connecting tube 1 all are hollow structure and can be interconnected.Junction surface one side on the flanged joint 2 has a circular protrusions 4; can adorn a circle seal ring or clamping plate in the periphery of projection 4 like this; the marginal distribution of projection 4 has four threaded connection holes 5 through flanged joint 2; the flange tapped hole that passes on bolt and the pipe fitting on seal ring or clamping plate and threaded connection hole 5 is fixed; can connect easily like this and well sealing; on the exterior edge face of flanged joint 3, be provided with groove 6; seal ring 7 is housed in groove 6; threaded connection hole 8 through flanged joint 3 is arranged at the edge of seal ring 7; can reach the convenient effect that connects and seal equally; be provided with a tapped hole 9 in the lower end of connecting tube 1; when normally using, the hole is tightened pipeline with screw; be convenient to turn on the bolt removal of contamination when working undesired or overhauling, it is convenient that pipe fitting is used; safety.
