Abstract
The utility model relates to an insertion type connecting pipe fitting for pipelines. The insertion type connecting pipe fitting for pipelines is composed of two parts of a pipe fitting body and a joint. The pipe fitting body is provided with a tee, a four-way, and a bent head. The insertion type connecting pipe fitting for pipelines is characterized in that the joint is composed of a joint body, a pressing nut, and a sealing ring. The interface position of the pipe fitting body is not provided with an inner connecting thread and an outer connecting thread. The insertion type connecting pipe fitting for pipelines has the advantages that when the insertion type connecting pipe fitting for pipelines is manufactured, a thread machine tool does not need to be used. When the insertion type connecting pipe fitting for pipelines is installed, a pipe does not need to use a hinging plate to be sheathed with a thread, therefore, the insertion type connecting pipe fitting for pipelines has low manufacturing cost, and convenient installation and disassembly. The insertion type connecting pipe fitting for pipelines is relatively used for a long time, the insertion type connecting pipe fitting for pipelines has no leakage. The insertion type connecting pipe fitting for pipelines is a more ideal connecting pipe fitting for pipelines.
Description
The utility model relates to the connection pipe fitting that a kind of pipeline is installed, particularly a kind of plug-in type pipeline connection pipe fitting.
The present pipeline connection pipe fitting that uses on the market, the connection of its connection part is mostly adopted and is threaded, this connection will could connect behind the screw thread on pipe hinge sleeve-board at pipe two when mounted, thereby it is strict to the wall thickness of used tubing, need when mounted to add and smear lead oil, twine fiber crops or adhesive tape, in case leak, dismounting, maintenance, replacing be difficulty very, and this is existing deficiency with connection pipe fitting.
The purpose of this utility model is a kind of plug-in type pipeline connection pipe fitting of design, this connection pipe fitting, dismounting, maintenance, replacing pipeline are conveniently, need not add during installation and smear lead oil, twine fiber crops or adhesive tape, not be used in hitch on the pipe of installation, particularly the time, require not tight the wall thickness of used tubing than low pressure, technical requirements is not high, in order to overcome existing deficiency with connection pipe fitting.
The purpose of this utility model can reach by following embodiment: the utility model is made up of pipe fitting and joint two-part, pipe fitting is threeway, four-way and elbow, be characterized in that joint is made of fittings body, gland nut, retaining seal ring, seal ring and water stop ring, the pipe fitting jointing does not have inside and outside connecting thread, and starting taper and triangle, circle, angular surface type, annular retaining seal groove are arranged on its interface cylindrical.There is outside thread at two ends, the fittings body left and right sides, and there is foreign side the centre, and its inwall is a cylindrical hole, inwall two ends band tapering seam and sealing annular groove; It is different warp that fittings body also can be made into two, promptly one pluckings one thin, two has the deformable joints of internal and external screw thread respectively, in order to the reducing pipeline and with the use that is connected of existing pipeline fitting.Gland nut is the nut that foreign side or circular embossing are arranged, and it is the nut of band tapering, internal diameter one is pluckings one thin, butt end band internal thread, thin end band tapering.
Assembly relation of the present utility model is: in the sealing annular groove of the fittings body of earlier water stop ring being packed into, successively retaining seal ring, seal ring are packed into again in the gland nut, gland nut is screwed on the screw thread of fittings body, then pipe fitting is inserted into correct position, tightens gland nut till reach installation requirement.
The utility model advantage is: 1) pipe fitting is no worm structure, need not use the machining screw facility during manufacturing, thereby has reduced cost; Pipe need not use pipe hinge plate when 2) pipeline was installed, and pipe is thread die cutting again, thus install simple, easy construction, and long-term relatively use not have leak, dismounting, maintenance, replacing are easy; 3) because pipe hitch not so can use the thin pipe of relative wall thickness, reduces the consumption of material; 4) owing to can manufacture reducing fittings,, conveniently make and management so can simplify the pipe fitting kind.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is an overall structure partial schematic sectional view of the present utility model;
Fig. 2 looks sectional view for the fittings body master;
Fig. 3 is the fittings body left view;
Fig. 4 is the gland nut partial sectional view;
Fig. 5 is the gland nut left view.
Shown in Fig. 1-5, this connection pipe fitting is made up of pipe fitting 1 and joint two-part, pipe fitting 1 is threeway, four-way and elbow, be characterized in that joint is made of fittings body 2, gland nut 3, retaining seal ring 4, seal ring 5 and water stop ring 6, pipe fitting 1 jointing does not have inside and outside connecting thread, and starting taper and annular retaining seal groove 1a are arranged on its interface cylindrical.There is outside thread at two ends, fittings body 2 left and right sides, and there is foreign side the centre, and its inwall is a cylindrical hole, inwall two ends band tapering seam and sealing annular groove 2a; It is reducing that fittings body 2 also can be made into two, promptly one pluckings one thin, two has internal and external screw thread respectively, or one have internal thread, one has externally threaded deformable joints, in order to the reducing pipeline and with the use that is connected of existing pipeline fitting.Gland nut 3 is outer square nut, and it is the nut of band tapering, internal diameter one is pluckings one thin, butt end band internal thread, thin end band tapering.Externally connected pipe 7 is an external tube.
The utility model retaining seal ring 4, seal ring 5 and water stop ring 6 are flexible or semi-rigid product, and pipe fitting 1, fittings body 2, gland nut 3 adopt metal or nonmetallic material product.
