Abstract
The invention provides a connecting structure used for pipeline union. The connecting structure comprises a movable joint, wherein one end of the movable joint is locked on a union body by a union nut, one end, close to the union body, of the movable joint is connected with the union body through a sealing ring for sealing, and the other end of the movable joint is externally provided with an interface in a socket form which is used for being connected with pipe fittings. The sealing between the movable joint and the union body is realized by the sealing ring, and the movable joint can be an internal thread movable joint or an external thread movable joint or a valve body or a valve cover of a valve. The connecting structure has the beneficial effects that the radial dimension of the pipe fittings or the valve is reduced, the installation space is saved, and the pipeline is more attractive; the material consumption is greatly reduced under the condition of ensuring the water flow diameter; the movable joint provided by the invention can be completely interchanged with the thread movable joint with the corresponding specification; more flexibility is provided for pipeline connection due to the direct connection manner of the pipe fittings.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to the pipeline interconnection technique, particularly a kind of loose joint structure connected for socket joint.
Background technique:
In prior art, for the loose joint structure of metallic conduit, internal thread loose joint and two kinds of structural types of outer silk loose joint are arranged, i.e. union is connected with the loose joint body and internal thread or an interface outward externally is provided.And the 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 the 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 the 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.
Summary of the invention:
The object of the present invention is to provide a kind of linkage structure for pipeline loose jointed, the described this linkage structure for pipeline loose jointed will solve the prior art union and adopt the bellmouth form and cause the technical problem that the radial structure size is large, manufacture cost is high.
This linkage structure for pipeline loose jointed of the present invention, be applicable in the pipeline of socket joint connection, comprise a union, one end of described union is affixed on the loose joint body by a loose joint nut lock, union is connected with the loose joint body by seal ring and realizes sealing near an end of loose joint body, wherein, the other end of union externally provides the interface of a socket form, for directly being 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 the external-thread union body, or the valve body of valve or valve gap.
Working principle of the present invention is: when union is connected with the loose joint body, an end of union is affixed on the loose joint body by a loose joint nut lock, and union is connected with the loose joint body by seal ring near an end of loose joint body, realizes sealing.The other end of union externally provides the interface of a socket form, for directly being connected with pipe fitting.Further, realize sealing reliably by seal ring between union and loose joint body; The loose joint body can be internal thread loose joint body, or the external-thread union body, or the valve body of valve or valve gap.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention changes the connection interface of union in prior art into the socket form by the bellmouth form, for directly being 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 exchanging fully with the threaded for union of corresponding specification, this has also promoted the flexibility that pipeline connects greatly.
The accompanying drawing explanation:
Fig. 1 is a loose joint body of a kind of linkage structure for the pipeline loose jointed of the present invention embodiment's that is internal thread loose joint body schematic diagram.
Fig. 2 is an embodiment's that the loose joint body is the external-thread union body of a kind of linkage structure for pipeline loose jointed of the present invention schematic diagram.
Fig. 3 is an embodiment's that the loose joint body is valve of a kind of linkage structure for pipeline loose jointed of the present invention schematic diagram.
Embodiment:
Embodiment 1:
As shown in Figure 1, a kind of linkage structure for pipeline loose jointed of the present invention, be applicable in the pipeline of socket joint connection, comprise a union 1, wherein, be provided with a radial convex on the excircle of described union 1 and go out step 6, the end face that the excircle of union 1 one end ends 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, be arranged with a nut 2 on the excircle of union 1, described nut 2 one ends 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 the realization sealing.In practical application, the sealing between union 1 and loose joint body 4 can also be passed through the 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 invention is: when union 1 is connected with loose joint body 4, an 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 an end of loose joint body 4, realizes sealing.The other end of union 1 externally provides the interface 7 of a socket form, for directly being connected with pipe fitting 5.Further, realize sealing reliably by seal ring between union and loose joint body; The loose joint body can be internal thread loose joint body, or the external-thread union body, or the valve body of valve or valve gap.
