Abstract
The utility model discloses a leak-proof pipe. The present pipe is poor in sealing property and is easy to leak. The leak-proof pipe comprises a first pipe joint and a second pipe joint, wherein the first pipe joint is provided with an external thread section; the second pipe joint is provided with an internal thread section; the leak-proof pipe is characterized in that a sealing ring facing to an outer end face of the external thread section is arranged on the second pipe joint in the position of the inner end of the internal thread section; and after the first pipe joint and the second pipe joint are connected through the internal thread section and the external thread section, the outer end face of the external thread section is extruded and pressed on the sealing ring, so as to realize sealing and avoid leakage.
Description
Technical field
The utility model belongs to pipe coupling, specifically is a kind of leakproof pipe fitting.
Background technique
The existing pipe fitting (being also referred to as pipe joint) that is used to connect pipe, poor sealing performance is prone to leak.
The model utility content
The technical problem that the utility model will solve and the technical assignment of proposition are to overcome existing pipe fitting poor sealing performance, are prone to the defective of leakage, and a kind of leakproof pipe fitting is provided.
For achieving the above object; The leakproof pipe fitting of the utility model; Comprise first pipe joint, second pipe joint; Described first pipe joint has external thread section, and described second pipe joint has internal thread segment, it is characterized in that: be positioned at the inner position of said internal thread segment on described second pipe joint and settle a seal ring towards said external thread section exterior edge face.
As the optimization technique means, described second pipe joint is provided with positioning ring groove, and described seal ring places in the described positioning ring groove.Further, the inward flange of said seal ring is concordant with the inwall of said second pipe joint.
As the optimization technique means, described first pipe joint comprises that plastic body and the metal reinforcement that is embedded in the said plastic body constitute, and described external thread section is formed on the described metal reinforcement.Further, the plastic body of said dorsad external thread section one end is provided with the hot melt interface on described first pipe joint.Described plastic body forms and is positioned at the inboard inwall of said external thread section, and this inwall is longer than described external thread section.
As the optimization technique means, described second pipe joint comprises that plastic body and the metal reinforcement that is embedded in the said plastic body constitute, and described internal thread segment is formed on the described metal reinforcement.Further, the plastic body of said dorsad internal thread segment one end is provided with the hot melt interface on described second pipe joint.Described plastic body forms and is positioned at the inboard inwall of said internal thread segment.
The beneficial effect of the utility model is: settle the seal ring of an outward thread section exterior edge face through on second pipe joint, being positioned at the inner position of internal thread segment; After win pipe joint and second pipe joint are linked together through internal thread segment, external thread section; The external thread section exterior edge face is squeezed in realizes sealing on the seal ring, avoid leaking.

Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The leakproof pipe fitting of the utility model; As shown in Figure 1; It comprises first pipe joint 01, second pipe joint 02; First pipe joint 01 has external thread section 11, the second pipe joints 02 and has and be positioned at the inner positions of internal thread segment 21 on internal thread segment 21, the second pipe joints 02 and settle the seal ring 03 of an outward thread section exterior edge face 12.After win pipe joint 01 and second pipe joint 02 were linked together through internal thread segment 11, external thread section 21, external thread section exterior edge face 12 is squeezed in realized sealing on the seal ring 03, avoid leaking.
As further improving and replenishing to technique scheme; The utility model also comprises following additional technical characteristics, though Fig. 1 has comprised following all additional technical features, is the preferred embodiment of the utility model; But the utility model is not limited to this situation; When implementing the utility model, according to specifically acting on they are selected for use on the described technological scheme of epimere: at first, second pipe joint 02 is provided with positioning ring groove 22, and seal ring 03 places in the positioning ring groove 22; Be squeezed when avoiding connecting and disengaging configuration causes poorly sealedly, this measure is particularly useful for the seal ring processed with silica gel (material is softer); Further, the inward flange of seal ring 03 is concordant with the inwall of second pipe joint 02, neither influences the circulation internal diameter of pipe fitting, can protect big to the greatest extent card sealing effect again.Secondly, first pipe joint 01 comprises that plastic body 13 and the metal reinforcement 14 that is embedded in the plastic body 13 constitute, and external thread section 11 is formed on the metal reinforcement 14, increases the intensity of first pipe joint thus.Further, on first pipe joint 01 dorsad the plastic body of external thread section 11 1 ends be provided with hot melt interface 15, be used for connecting pipe through the hot melt means; Plastic body 13 forms the inwall that is positioned at external thread section 11 inboards, and this inwall is longer than external thread section 11.The 3rd; Second pipe joint 02 comprises that plastic body 23 and the metal reinforcement 24 that is embedded in the plastic body 23 constitute; Internal thread segment 21 is formed on the metal reinforcement 24, increases the intensity of second pipe joint 02 thus, further; On second pipe joint 02 dorsad the plastic body of internal thread segment 21 1 ends be provided with hot melt interface 25, be used for connecting pipe through the hot melt means; Plastic body 23 forms inwall 26.Under coupled condition; The inwall of two pipe joints forms the inner passage of whole pipe fitting; And the inwall 16 of first pipe joint 01 is longer than better crush seal circle and the inner passage of the metal reinforcement of two pipe joints and pipe fitting isolated of external thread section 11, avoids metal reinforcement by dielectric corrosion.
