Description
Technical field
This utility model belongs to pipe fitting technical field, is specifically related to a kind of pipe fitting carrying sealing device.
Background technology
Pipe fitting is the part that pipe connects into pipeline.Socket fitting, threaded fitting, method can be divided into according to method of attachment
Blue pipe fitting and weld-end fittings four class.The multiplex material identical with pipe is made.There are elbow (ell), flange, tee T, four-way pipe
(crosshead) and reduced pipe (concentric reducer) etc..Elbow is for the place of pipeline turning；Flange is used for making pipe interconnect mutually with pipe
The part connect, is connected to pipe end, the place that tee T collects for three pipes；The ground that four-way pipe collects for four pipes
Side；Reduced pipe is used for the place that the two tubes of different tube diameters is connected.Current pipe fitting is generally and uses plastic pipe or gold
Belong to pipe fitting, such as cast iron pipe fittings, but no matter be to use what pipe fitting, be the most all directly on pipe fitting inner wall, to open threaded joints
Or have male threaded joint, it is directly connected to pipeline, when the pipe fitting of this structure connects, due between pipe fitting joint and pipe fitting
Diameter there are differences, poor sealing performance, seals to this end, be typically to be provided with sealing member when mounted, in case the generation of leak-stopping liquid, this
Sample operates cumbersome, is unfavorable for that installs is smoothed out.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provide a kind of pipe fitting carrying sealing device.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of pipe fitting carrying sealing device, including the first threaded pipe fitting and the second pipe fitting, described first pipe fitting
Having external thread part, described second pipe fitting has internal thread part, and the port installation by adhering of described external thread part has seal washer,
The bottom of the internal thread part of described second pipe fitting has packing ring limited step.
The port of described external thread part has packing ring and installs cannelure, and described seal washer has and described packing ring mounting ring
The annular protrusion of shape slot fit, described annular protrusion inserts described packing ring and installs cannelure and make described seal washer and described the
The port of the external thread part of one pipe fitting is connected.
The outboard end of the internal thread part of described second pipe fitting has cannelure, the described external screw thread of connection of described first pipe fitting
The corresponding side of the pipe fitting matrix in portion has the groove of the annular that may be inserted in described cannelure.
The first pipe fitting and the first pipe fitting of the second pipe fitting that this utility model is threaded connection have external thread part, described
Second pipe fitting has internal thread part, and the port installation by adhering of described external thread part has seal washer, described second pipe fitting interior
The bottom of threaded portion has packing ring limited step so that after the two carries out inner sealing by seal washer, sealing property is able to
Strengthen, especially because seal washer is directly installed on external thread part, eliminates and look for the trouble that packing ring is installed again.
It addition, by there is cannelure, the company of described first pipe fitting at the outboard end of the internal thread part of described second pipe fitting
The corresponding side of the pipe fitting matrix connecing described external thread part has the groove of the annular that may be inserted in described cannelure, Ke Yitong
Cross ring part to insert in described cannelure, it is achieved the overlap that again carries out between the first pipe fitting and the second pipe fitting seals, close
Sealing property is enhanced.

Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this practicality is new
Type is not limited to listed embodiment.
Seeing shown in Fig. 1-4, a kind of pipe fitting carrying sealing device, including the first threaded pipe fitting 10 and the second pipe
Part 20, described first pipe fitting has external thread part 12, and described second pipe fitting has internal thread part 22, the port of described external thread part
Installation by adhering has seal washer 13, the bottom of the internal thread part of described second pipe fitting, i.e. connects the company of pipe fitting body passageways 21
Connect position, there is packing ring limited step.
Wherein, concrete, the port of described external thread part has packing ring and installs cannelure 121, and described seal washer has
With the annular protrusion 131 that described packing ring installs annular slot fit, this annular protrusion 131 is connected for integral type with packing ring base portion 130
Structure, described annular protrusion inserts described packing ring and installs cannelure and makes the external screw thread of described seal washer and described first pipe fitting
The port in portion is connected.
Further, in this utility model, the outboard end of the internal thread part of described second pipe fitting has cannelure 24, institute
The corresponding side of the pipe fitting matrix 11 connecting described external thread part stating the first pipe fitting has and may be inserted into described cannelure 24
In annular groove.
The first pipe fitting and the first pipe fitting of the second pipe fitting that this utility model is threaded connection have external thread part, described
Second pipe fitting has internal thread part, and the port installation by adhering of described external thread part has seal washer, described second pipe fitting interior
The bottom of threaded portion has packing ring limited step so that after the two carries out inner sealing by seal washer, sealing property is able to
Strengthen, especially because seal washer is directly installed on external thread part, eliminates and look for the trouble that packing ring is installed again.
It addition, by there is cannelure, the company of described first pipe fitting at the outboard end of the internal thread part of described second pipe fitting
The corresponding side of the pipe fitting matrix connecing described external thread part has the groove of the annular that may be inserted in described cannelure, Ke Yitong
