Abstract
The utility model relates to a fast installing tube joint of a high sealing thin wall tube. The pressurization bevel of a compacting inner screw rod body of the utility model directly tightly presses a bellmouth of the thin wall tube; compared with the old compacting of the bellbouth of the thin wall tube through an elastic rubber ring, the connection is firmer. The pressurization bevel, a sealing bevel and the bellmouth of the thin wall tube are mutually parallel and form a parallel hard sealing face after compacting; thereby, the leakage caused by the aging of the rubber ring is avoided. An elastic sealing ring is sheathed on steps of the compacting inner screw rod body, which not only affects the firm connection of the thin wall tube but also increases the sealing effect.
Description
The utility model relates to a kind of fast holding pipe joint of thin walled tube of high leak tightness.
Connection between the existing thin walled tube, the employing welding process that has, though good airproof performance, construction process is complicated; Another kind method is form to connect at the thin walled tube upper overturning, uses seal with elastometic washer, and the shortcoming of prior art is a thin walled tube with the pipe joint joint is to contact, and thin walled tube is stressed easily to be rocked, and makes the sealability variation.
The purpose of this utility model provides a kind of fast holding pipe joint of thin walled tube of high leak tightness, and it has higher sealability, and connects conveniently reliable.
The purpose of this utility model is to realize like this, the fast holding pipe joint of a kind of thin walled tube of high leak tightness is formed by managing junctor (2) and compressing the interior Luo body of rod (7), there is a sealing inclined-plane (1) to parallel on its pipe junctor (2) with thin walled tube horn mouth front junction surface, Luo body of rod head has a pressurization inclined-plane (5) to form parallel with the thin walled tube horn mouth back side in compressing, be screwed into compress in during the Luo body of rod (7), the pressurization parallel extruding thin walled tube horn mouth back side, inclined-plane (5), thin walled tube horn mouth front closely is connected with sealing inclined-plane (1), form parallel hard sealing surface, it is slightly long to be enclosed within elastic seal ring (4) axial length that compresses on the interior Luo body of rod step (6), when the Luo body of rod is tightened in compressing, elastic seal ring (4) is subjected to squeeze and forms another road sealing surface, and the lead-in chamfered (3) on the pipe junctor is beneficial to the thin walled tube installation and puts in place smoothly.
Main advantages of the present utility model is: the pressurization inclined-plane of the Luo body of rod directly compresses the thin walled tube horn mouth in compressing, and connects more firm compared with compressing the thin walled tube horn mouth by flexible rubber ring in the past; The pressurization inclined-plane, sealing inclined-plane and thin walled tube horn mouth are parallel to each other, and compress the back and form parallel hard sealing surface, have got rid of rubber ring and have worn out and cause leakage; On the Luo body of rod step, neither influence thin walled tube and firmly connect in elastic seal ring is enclosed within and compresses, again can the enhanced leaktightness effect.
Structure of the present utility model is provided by following examples and accompanying drawing: Fig. 1 is a theory structure of the present utility model.For simplicity, some lines of reflection view have been omitted on the drawing.Earlier elastic seal ring (4) is enclosed within and compresses on the interior Luo body of rod step (6), the Luo body of rod (7) is inserted in thin walled tube (8) in will compressing, after thin walled tube pressed horn mouth, push pipe junctor (2), tighten and compress the interior Luo body of rod, the pressurization inclined-plane (5) of Luo body of rod head is parallel to each other with thin walled tube horn mouth and pipe junctor sealing inclined-plane (1) in compressing, and forms parallel hard sealing surface, and make elastic seal ring (4) distortion, form another road sealing surface.Lead-in chamfered (3) on the pipe junctor is beneficial to when thin walled tube is installed and puts in place smoothly.It is identical with the conventional tube junctor that the pipe junctor connects kind, i.e. elbow, threeway etc. is not repeated.
Claims (1)
1. the fast holding pipe joint of the thin walled tube of a high leak tightness, it is characterized in that fast holding pipe joint is by pipe junctor (2) with compress the interior Luo body of rod (7) and form, there is a sealing inclined-plane (1) to parallel on its pipe junctor (2) with thin walled tube horn mouth front junction surface, Luo body of rod head has a pressurization inclined-plane (5) to form parallel with the thin walled tube horn mouth back side in compressing, be screwed into compress in during the Luo body of rod (7), the pressurization parallel extruding thin walled tube horn mouth back side, inclined-plane (5), thin walled tube horn mouth front closely is connected with sealing inclined-plane (1), form parallel hard sealing surface, it is slightly long to be enclosed within elastic seal ring (4) axial length that compresses on the interior Luo body of rod step (6), when the Luo body of rod is tightened in compressing, elastic seal ring (4) is subjected to squeeze and forms another road sealing surface, and the lead-in chamfered (3) on the pipe junctor is beneficial to the thin walled tube installation and puts in place smoothly.
