Abstract
The utility model provides a pipe joint for industrial pipelines, which comprises a circular short pipe (1) butted with a circular short pipe (2), the pipe joint is characterized in that ear bases (3) with bolt holes are arranged on the outer walls of the short pipe (1) and the short pipe (2), and the short pipe (1) and the short pipe (2) are butted together by a screw bolt (4) and a nut (5) through the ear base (3). An annular sealing ring (6) is arranged on the contact faces of the abutting ends of the short pipe (1) and the short pipe (2). The utility model has the advantages of simple structure, low cost and convenient installation.
Description
The utility model relates to a kind of pipe joint that is used for industrial pipeline.
The pipe joint that is used for industrial pipeline at present has the flexible tube head of clamp band type, and the advantage of this flexible pipe joint is easy for installation, and its not enough here is a complex structure, the manufacture cost height; Another kind of pipe joint is a flanged joint, and the advantage of this pipe joint is that cost is low, and its deficiency is that inconvenience is installed.
The purpose of this utility model is to provide a kind of simple in structure, pipe joint that cost is low, easy for installation, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of pipe joint, it comprises that a circular short tube (1) and another circular short tube (2) connect, its improvements are to have the ear seat (3) in strap bolt hole on the outer wall of short tube (1) and short tube (2), bolt (4) and nut (5) are docking together short tube (1) and short tube (2) by ear seat (3), the seal ring (6) that has ring-type on the surface of contact between short tube (1) and short (2) butt end.
The utility model pipe joint can be that the surface of contact between short tube (1) and short tube (2) butt end is a sphere.
The utility model pipe joint can be that the surface of contact between short tube (1) and short tube (2) butt end is the conical surface.
The utility model pipe joint can be to have corrosion resistant coating on the surface of contact between short tube (1) and short tube (2) butt end.
The utility model pipe joint can be that the inwall at short tube (1) and short tube (2) has one deck wearing layer (7).
The utility model pipe joint can be that wearing layer (7) is a ceramic wearing coat.
The utility model pipe joint can be that wearing layer (7) is the cast stone wearing layer.
The utility model pipe joint can be that wearing layer (7) is the wear-resistant paint coating.
The pipe joint that the utility model provides, cost simple in structure is low, and is easy for installation.Surface of contact between two short tube butt ends is the pipe joint of sphere, under the inconsistent situation of axis of two pipes that are connected, can install smoothly, and at running, under the situation that the axis of pipe changes, the pipe joint place is not easy to leak.
Fig. 1, the master of the utility model pipe joint looks partial sectional view.
Fig. 2, the right elevation of Fig. 1.
Fig. 3, the master of the pipe joint of another kind of structural type looks partial sectional view.
The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.
Embodiment 1, Fig. 1, Fig. 2 have provided a kind of concrete structure of the utility model pipe joint, consult Fig. 1 and Fig. 2, it comprises that a circular short tube (1) and another circular short tube (2) connect, on the outer wall of short tube (1) and short tube (2), has the ear seat (3) that has bolt hole, bolt (4) and nut (5) are docking together short tube (1) and short tube (2) by ear seat (3), the seal ring (6) that has ring-type on the surface of contact between short tube (1) and short tube (2) butt end.Seal ring (6) can be selected the corrosion protection rubber ring for use.Surface of contact between short tube (1) and short tube (2) butt end is a sphere.On the surface of contact between short tube (1) and short tube (2) butt end, have one deck corrosion resistant coating, prevent that the corrosion that surface of contact is subjected to medium from leaking.Inwall at short tube (1) and short tube (2) has one deck wearing layer (7), and wearing layer (7) can be ceramic wearing coat or cast stone wearing layer, also can be the wear-resistant paint coating, improves wear resistance.When construction, short tube is welded on the installation of promptly carrying out pipeline on the tubing.The pipe joint of this structure, because surface of contact is a sphere between short tube (1) and short tube (2) butt end, under the inconsistent situation of axis of two pipes that are connected, can install smoothly, at running, under the situation that the axis of pipe changes, the pipe joint place is not easy to leak, and is embodiment preferably.
Embodiment 2, Fig. 3 has provided another concrete structure of the utility model, consult Fig. 3, it comprises that a circular short tube (1) and another circular short tube (2) connect, on the outer wall of short tube (1) and short tube (2), has the ear seat (3) that has bolt hole, bolt (4) and nut (5) are docking together short tube (1) and short tube (2) by ear seat (3), the seal ring (6) that has ring-type on the surface of contact between short tube (1) and short tube (2) butt end.Surface of contact between short tube (1) and short tube (2) butt end is the conical surface.On the surface of contact between short tube (1) and short tube (2) butt end, has one deck corrosion resistant coating.Inwall at short tube (1) and short tube (2) has one deck wearing layer (7), and wearing layer (7) can be ceramic wearing coat or cast stone wearing layer, also can be the wear-resistant paint coating.
