Abstract
A thin-wall metal mouthing-typed press pipe joint relates to a metal pipe joint, in particular to a thin-wall metal pipe joint. The utility model includes a mouthing 1, the end of the mouthing is provided with a position limit concave trough 6; a mouthing cylinder body is arranged between the position limit concave trough 6 and the mouthing port part with the internal wall in ring-shaped sealing trough 2 externally convex circumference; a sealing ring 3 arranged in the sealing trough 2; a pipe 7 which is inserted into stipulated position of the mouthing 1 and is tightly fixed; the left and right sides of the sealing ring 3 are pressed with a locking trough 4 with integrated internally concave circumference. The utility model has the advantages of dual locking, dual sealing, soundly arranged locking and sealing position, good locking and sealing effect, thus reinforcing the reliability and practicability of the joint.
Description
The utility model relates to metallic pipe coupling, particularly thin-wall metal pipe joint.
The metallic pipe coupling of prior art, its structural type are the reducing bell and spigot frame.The bellmouth end is provided with the seal groove of one circumference evagination, and groove is built-in with " O " shape rubber seal.Pipe inserted in the bellmouth push locking groove one with special tool.The interface situation is monolateral extrusion modling.Locking was not tight when its deficiency was that big or tube wall is too thin when external force, and is easily loosening under external force acts on repeatedly, can not be used for ultra-thin pipe and connect.Also having a kind of metal extruding type pipe joint, also is socket fitting type structure, and its deficiency is there is not limit structure, and insertion depth is wayward, and because circumference evenly pushes, and the extruding difficulty is locked the back pipe and easily rotated, it is little to bear torsion.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of connection reliable, and good sealing performance thin-wall metal mouthing is pressed the work pipe joint.
The purpose of this utility model can realize like this: design a kind of thin-wall metal mouthing and press the work pipe joint, comprise bellmouth, bellmouth end portion is provided with the bellmouth limited impression, be provided with the annular seal groove that the bellmouth cylinder inboard wall is the circumference evagination between bellmouth limited impression and the female end oral area, be located at the seal ring in the seal groove; Pipe inserts bellmouth to assigned position and fastening, in the left and right sides of seal ring, is pressing the locking groove that is incorporate circumference indent.
The utility model has strengthened the reliability and the practicability of joint.
Description of drawings.
Fig. 1 is the fastening preceding schematic representation of one of the utility model most preferred embodiment.
Fig. 2 is the schematic representation of one of the utility model most preferred embodiment after fastening.
Fig. 3 is two fastening preceding schematic representation of the utility model most preferred embodiment.
Fig. 4 is two schematic representation after fastening of the utility model most preferred embodiment.
Fig. 5 is the ring week sectional view of one of pressure work groove of the utility model most preferred embodiment.
Fig. 6 is two a ring week sectional view of the pressure work groove of the utility model most preferred embodiment.
The utility model is described in further detail below in conjunction with the embodiment shown in the accompanying drawing.
As Fig. 1, Fig. 2, Fig. 5 and shown in Figure 6, the utility model comprises bellmouth 1, and bellmouth end portion is provided with limited impression 6, is provided with the annular seal groove 2 that the bellmouth cylinder inboard wall is the circumference evagination between limited impression 6 and the female end oral area, is located at the seal ring 3 in the seal groove 2; Pipe 7 inserts bellmouth 1 to assigned position and fastening, in the left and right sides of seal ring 3, is pressing the locking groove 4 that is incorporate circumference indent.The seal ring that is contained in the seal groove is before pipe inserts, insert in the seal groove, pipe is inserted into assigned position limited impression 6 places, in the left and right sides of seal ring 3, with instrument with the bellmouth barrel with tube wall pressing be incorporate circumference indent locking groove 4 each.The circumferential ring section of locking groove 4 is trapezoidal closed shape; Or the circumferential ring section of locking groove 4 is not closed shape of polygonal; Or the circumferential ring section of locking groove 4 is not closed shape of a pressure ring shape.
Used seal ring is " O " shape, makes by elaxtic seal, as: rubber, graphite.
As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, seal groove 2 is located at the middle part of bellmouth cylindrical shell separately together, and second road is located at the female end oral area, and the circumferential ring section all is " C " font.The seal ring that is contained in the seal groove is before pipe inserts, insert in the seal groove, pipe is inserted into assigned position limited impression 6 places, in the left and right sides of seal ring 3, recruitment its with the bellmouth barrel with tube wall pressing be incorporate circumference indent locking groove 4 each.The circumferential ring section of locking groove 4 is trapezoidal closed shape; Or the circumferential ring section of locking groove 4 is not closed shape of polygonal; Or the circumferential ring section of locking groove 4 is not closed shape of a pressure ring shape.Used seal ring 3,5 all is " O " shape, can be made by different elaxtic seals.Use graphite as seal ring 3, seal ring 5 usefulness rubber or polyesters.
In order to guarantee sealing reliability, the evagination height of seal groove 2 changes in 3～16 millimeters scopes, and the indent degree of depth of binding groove generally changes in 1～4 millimeter scope.At the internal diameter of joint intermediate location internal diameter, reduced the liquid flow resistance loss greater than pipe.
Compare with prior art, the utility model twin-lock is solid, double containment, the setting of locking sealing station Rationally, the effect of locking sealing is better.
