Abstract
The utility model relates to a pipeline joint, particularly an end sealed sleeving type locking pipeline joint. A sealing ring (3) is arranged on an inner cylindrical hole (8) of a pipe joint (1); a locking ring (4) is arranged on an inner conical surface (7); a clamping thread bush (2) is arranged on an inner screw thread (6) on the end of a pipe so one-way, or elbow, or three-way, or four-way pipeline joints can be formed. The utility model adopts end surfaces to press and seal, and pointed teeth are inserted into the pipe wall when the pipe is locked, and the clamping thread bush adopts an internal sleeve type; therefore, the effective length of joint of the thread brush and the pipe is increased. Thus the pipeline joint has favorable transverse stability. Because the pipes need no threading, the pipeline joint can be installed conveniently and quickly. The pipeline joint is suitable for various connections of pipelines.
Description
The utility model relates to pipe coupling, particularly a kind of end face seal internal cover type locking pipe joint.
Pipeline connects the mantle fibers that adopt more and connects in the prior art, because of need at tube end headgear silk, so require tubing matter harder, tube wall is thicker, thereby has limited the application of the tubing of some kinds in pipe-line system.
In pipeline connects, also adopt a kind of ready-packaged joint to connect, need not that mantle fiber is carried out in the pipe termination and handle.But adopt of the sealing of this class joint seals on tube wall more, and promptly packing matcrial is finished between pipe junctor inwall and pipe outer arm.Because sealing and the locking of ready-packaged joint are to carry out simultaneously, only depend on the tube wall sealing to be difficult in the process of locking pipe and guarantee sealing effect, often good seal occurred but locked badly, perhaps lock and got well but seal bad phenomenon.
The purpose of this utility model is: a kind of end face seal internal cover type locking pipe joint is provided, need not mantle fiber is carried out in the pipe termination, use simple setting tool, can connect pipeline fast.
Formation of the present utility model: form by pipe junctor, gland nut, seal ring, clamp ring, on the interior cylindrical hole of pipe junctor (1), seal ring (3) is installed, clamp ring (4) is installed on the inner conical surface, the outside thread of gland nut (2) is connected with the internal thread of pipe junctor (1), form to lead directly to, elbow, threeway, four-way pipe coupling.Pipe junctor (1) is cylindric, in the tube internal thread (6), inner conical surface (7), inner cylindrical surface (8) and seam step (9) is arranged.Gland nut (2) is a tubular, and outer wall has cap head (10) and outside thread (11).Seal ring (3) is cylindric, and an end has quarter bend discount (12) entad.Clamp ring (4) is a ring, is provided with opening (13), and outer wall has conical surface (14), and inwall has several pointed tooth bars (15) along the circumferential direction.
Compared with the prior art, the utility model is rational in infrastructure, adopts end face to compress and guarantees to seal, and adopts pointed tooth to embed tube wall when the locking pipe, utilizes the shearing drag to guarantee locking effect.Gland nut adopts internal cover type, and what increased swivel nut and pipe effectively combines length, thereby has good lateral stability.Because pipe is therefore quick and easy for installation without mantle fiber.
Accompanying drawing 1 is the utility model connection diagram;
Accompanying drawing 2 is pipe junctor structural representations;
Accompanying drawing 3 is gland nut structural representations;
Accompanying drawing 4 is seal ring structure schematic representation;
Accompanying drawing 5 is sectional views of accompanying drawing 4;
Accompanying drawing 6 is clamp ring structural representations;
Accompanying drawing 7 is sectional views of accompanying drawing 6.
Embodiment of the present utility model: as shown in drawings, with gland nut (2), clamp ring (4), seal ring (3) is enclosed within on the pipe (5) successively, insertion tube junctor (1), arrive to seam step (9), tighten gland nut (2), gland nut (2) is passed clamp ring (4) forward, when clamp ring touches the conical surface (7) of managing in the junctor, because the conical surface (14) in the clamp ring is done the inclined-plane motion mutually with the conical surface in the pipe junctor, the pointed tooth (15) of compressing clamp ring embeds tube wall, thereby pipe is firmly pinned, in the whole process of locking pipe, pipe is subjected to the power of supporting before one always, and the front end bending head (12) of the seal ring (3) of elastic material is squeezed, and plays the end face seal effect.The barrel of seal ring (3) can play the auxiliary seal effect, and forms the front end localization part of pipe with the cylndrical surface (8) of pipe in the junctor, and the inwall of it and gland nut is clamped down on pipe jointly, has strengthened the lateral stability of pipe.
Claims (5)
1, a kind of end face seal internal cover type locking pipe joint, form by pipe junctor, gland nut, seal ring, clamp ring, it is characterized in that: on the interior cylindrical hole of pipe junctor (1), seal ring (3) is installed, clamp ring (4) is installed on the inner conical surface, the outside thread of gland nut (2) is connected with the internal thread of pipe junctor (1), form to lead directly to, elbow, threeway, four-way pipe coupling.
2, end face seal internal cover type locking pipe joint according to claim 1 is characterized in that: pipe junctor (1) has internal thread (6), inner conical surface (7), inner cylindrical surface (8) and seam step (9) for cylindric in the tube.
