Abstract
The utility model relates to a novel pipe fitting, particularly a machine part. A joint of a pipe fitting body is sheathed with a lining sleeve and a pipe fitting sleeve; a slot is arranged on the conical surface of the joint of the pipe fitting body; a sealing ring is inserted in the slot; the pipe fitting is a straight-through pipe fitting, a end straight-through pipe fitting, a three-way pipe fitting, a four-way pipe fitting or a right-angle pipe fitting. The utility model has the advantages that the pipe fitting body is connected with an external connection pipe; the pipe fitting body is sheathed with the lining sleeve and a pipe fitting cap. When the pipe fitting cap is tightly screwed, an O-shaped ring is compacted, and simultaneously, the edge of a taper hole of the pipe sleeve and the opening expanding edge of the metal external connection pipe are slightly flanged outwards; therefore, the sealing performance, the pressure-resistance performance and the connection fasteness can be obviously improved. The utility model also provides the conical surface on the end part of the joint body and the optimum taper of the taper hole of the lining sleeve; therefore, the utility model has the advantages of simple structure, convenient operation, reliable performance, stable performance, high pressure-resistance performance, high sealing performance and high connection fasteness.
Description
Technical field:
The utility model relates to mechanical parts, especially pipe fitting.
Background technique:
Traditional pipe fitting comprises flared type and FERRULETYPE, direct enlarging suit of externally connected pipe or cutting ferrule are stuck on the Guan Shangyu fittings body, there is not any sealing, can produce seepage under the proper functioning, in stressed strong or more leakiness, lot when being subjected to strong vibration, particularly when being used for the conveyance conduit of high-temperature, high pressure fluid, its sealing withstand voltage properties and degree of being connected firmly are obviously not enough, do not reach usage requirement.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of novel pipe fitting is provided, and is simple in structure, and the sealing withstand voltage properties is good, is connected firmly.
The utility model is that the technological scheme that is adopted that achieves the above object is: novel pipe fitting, be set with lining and pipe fitting cover on the pipe fitting joint, and slot embedded sealing ring in the groove on the pipe fitting joint conical surface.
The tapering of lining taper hole is less than fittings body end conical surface tapering 0.1-0.3 degree; Described seal ring is a rubber seal, can be O shape or rectangular rubber circle.
Described pipe fitting is for straight-through, and end is straight-through, threeway, four-way or right angle.
When pipe fitting leads directly to for end, also slot on the end face, place seal ring in the groove.
The utility model has the advantages that: pipe fitting connects externally connected pipe, put lining and pipe fitting cap, when screwing tight the pipe fitting cap, except that O shape ring is compressed, pipe box taper hole edge and metal externally connected pipe enlarging edge can omit outward flanging simultaneously, have just obviously improved sealing withstand voltage properties and degree of being connected firmly.The utility model also provides the best tapering of the fittings body end conical surface and lining taper hole, and is simple in structure, easy-to-operat, and reliable performance is stable, and higher pressure-resistant stopping property and degree of being connected firmly are arranged.
Description of drawings:
Fig. 1 is the utility model bypass structure schematic representation.
Fig. 2 is the utility model end bypass structure schematic representation.
Fig. 3 is the utility model three-port structure schematic representation.
Fig. 4 is the utility model right-angle structure schematic representation.
Concrete mode of execution:
Straight-through as the novel pipe fitting that Fig. 1 shows, pipe fitting 1 outer suit lining 4 and pipe fitting cap 2, the pipe fitting joint end conical surface has annular groove, and O-ring seals is inlaid in the annular groove of the pipe fitting joint end conical surface, after metal tube 5 inserts lining, line up is implemented enlarging, then carries out attaching, in the process that screws the pipe fitting cap, O shape ring is compacted, the metal mouth of pipe and lining taper hole edge can omit outward flanging simultaneously, thereby have improved resistance to pressure and sealing, have also improved degree of being connected firmly.It is straight-through that this kind structural design is suitable for reducing equally.
End as shown in Figure 2 is straight-through, pipe fitting 1 outer suit lining 4 and pipe fitting cap 2, and the pipe fitting joint end conical surface has annular groove, and O shape rubber seal is inlaid in the annular groove of the pipe fitting joint end conical surface, also establishes fluting on the end face, places cabinet shape seal ring in the groove.
Threeway as shown in Figure 3, pipe fitting 1 outer suit lining 4 and pipe fitting cap 2, the pipe fitting joint end conical surface has annular groove, and O shape rubber seal is inlaid in the annular groove of the pipe fitting joint end conical surface.The four-way similar is in threeway.
Right angle as shown in Figure 4, pipe fitting 1 outer suit lining 4 and pipe fitting cap 2, the pipe fitting joint end conical surface has annular groove, and O shape rubber seal is inlaid in the annular groove of the pipe fitting joint end conical surface.
