Abstract
The utility model discloses a connecting structure used for a pipeline loose joint. The connecting structure comprises a loose joint head. One end of the loose joint head is locked to a loose joint body by a loose joint nut, and the end, close to the loose joint body, of the loose joint head is connected with the loose joint body through a sealing ring to achieve sealing. An insertion-opening-type connector is provided outwards through the other end of the loose joint head and is used for being directly connected with a pipe. Sealing between the loose joint head and the loose joint body is achieved through the sealing ring. The loose joint body can be an internal-thread loose joint body or an external-thread loose joint body or a valve body or valve cover of a valve. Due to the adoption of the connecting structure used for the pipeline loose joint, the radial dimension of the pipe or valve is reduced, installing space is saved, and a pipeline looks more beautiful; the water flow drift diameter is guaranteed, and material consumption is greatly reduced as well; the loose joint head and thread loose joint heads of corresponding specifications can be completely interchangeable; the mode that pipes are directly connected provides more flexibility for pipeline connection.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pipeline interconnection technique, particularly a kind of loose joint structure connecting for socket joint.
Background technique:
In prior art, for the loose joint structure of metallic conduit, have internal thread loose joint and two kinds of structural types of outer silk loose joint, i.e. union is connected with loose joint body and internal thread or an interface outward is externally provided.And plastic cement pipeline adopts socket joint to connect because plastic pipe self-assembling formation an outlet structure, so on pipe fitting or valve, union is made to bellmouth form, to be connected with tubing.But there are a lot of disadvantages in the loose joint structure of this bellmouth form.For example radial structure size is bigger than normal; High to requirements of installation space, and affect attractive in appearance; The size of pipe fitting or valve is larger, pipe fitting or the valve that particularly for some, need to adopt metal (as copper, stainless steel etc.) material to manufacture, and its cost consumption is appreciable; And pipe fitting and tubing to be connected compound mode dumb.
Model utility content:
The purpose of this utility model is to provide a kind of linkage structure for pipeline loose jointed, and the described this linkage structure for pipeline loose jointed will solve prior art union and adopt bellmouth form and cause the technical problem that radial structure size is large, manufacture cost is high.
This linkage structure for pipeline loose jointed of the present utility model, be applicable in the pipeline of socket joint connection, comprise a union, one end of described union is affixed on loose joint body by a loose joint nut lock, union is connected with loose joint body by seal ring near one end of loose joint body and realizes sealing, wherein, the other end of union externally provides the interface of a socket form, for being directly connected with pipe fitting.
Further, the sealing between described union and loose joint body realizes by seal ring, and seal ring comprises conical surface wedging seal ring or inside and outside circle compresses seal or end face press seal circle.
Further, described loose joint body is internal thread loose joint body, or external-thread union body, or the valve body of valve or valve gap.
Working principle of the present utility model is: when union is connected with loose joint body, one end of union is affixed on loose joint body by a loose joint nut lock, and union is connected with loose joint body by seal ring near one end of loose joint body, realizes sealing.The other end of union externally provides the interface of a socket form, for being directly connected with pipe fitting.Further, between union and loose joint body, by seal ring, realize sealing reliably; Loose joint body can be internal thread loose joint body, or external-thread union body, or the valve body of valve or valve gap.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model changes the connection interface of union in prior art into socket form by bellmouth form, for being directly connected with pipe fitting, greatly reduced the radial dimension of pipe fitting or valve, save installing space, and make the pipeline after installation more attractive in appearance, in the situation that guarantee to use safety and identical current latus rectum, the consumption of material also reduces greatly, and provides pipeline more flexibly to connect combination.In addition, by suitable design, can realize with the threaded for union of corresponding specification and exchanging completely, this has also promoted the flexibility that pipeline connects greatly.
Accompanying drawing explanation:
Fig. 1 is a schematic diagram that loose joint body is the embodiment of internal thread loose joint body of the linkage structure for pipeline loose jointed of the present utility model.
Fig. 2 is that a loose joint body of the linkage structure for pipeline loose jointed of the present utility model is the embodiment's of external-thread union body schematic diagram.
Fig. 3 is an embodiment's that loose joint body is valve of the linkage structure for pipeline loose jointed of the present utility model schematic diagram.
Embodiment:
Embodiment 1:
As shown in Figure 1, linkage structure for pipeline loose jointed of the present utility model, be applicable in the pipeline of socket joint connection, comprise a union 1, wherein, on the excircle of described union 1, be provided with a radial convex and go out step 6, the end face that the excircle of union 1 end, one end and described radial convex go out step 6 is adjacent, the excircle of the described end of union 1 and radial convex go out between the described end face of step 6 to be provided with a seal ring 3, on the excircle of union 1, be arranged with a nut 2, described nut 2 one end are provided with circular step to axis direction, another end face that described circular step and described radial convex go out step 6 is adjacent, the internal diameter of circular step is less than the external diameter that radial convex goes out step 6.Union 1 externally provides the interface 7 of a socket form, for being connected with pipe fitting 5.Nut 2 is connected with loose joint body 4, and in the present embodiment, loose joint body 4 adopts an internal thread loose joint body.
Further, the seal ring wedging that union 1 is taper with loose joint body 4 by a cross section is connected realization sealing.In practical application, the sealing between union 1 and loose joint body 4 can also be passed through inside and outside circle compresses seal, or end face press seal circle is realized sealing.
Embodiment 2:
As shown in Figure 2, loose joint body 4 adopts an external-thread union body.
Embodiment 2:
As shown in Figure 3, loose joint body 4 is valve body or valve gaps of a valve.
Working principle of the present utility model is: when union 1 is connected with loose joint body 4, one end of union 1 is locked on loose joint body 4 by a loose joint nut 2, and union 1 is connected with loose joint body 4 by seal ring 3 near one end of loose joint body 4, realizes sealing.The other end of union 1 externally provides the interface 7 of a socket form, for being directly connected with pipe fitting 5.Further, between union and loose joint body, by seal ring, realize sealing reliably; Loose joint body can be internal thread loose joint body, or external-thread union body, or the valve body of valve or valve gap.
