Description
Technical field
The utility model relates to pipe joint field, is specifically related to a kind of feedwater pipe joint.
Background technique
The fittings body position of existing feedwater pipe joint generally adopts screw-thread fit, and sealability is poor, and long-time use there will be water leakage phenomenon, and needs to use special tool in unloading process, bothers very much, is badly in need of improving.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of feedwater pipe joint, easy installation and removal, good seal performance.
For achieving the above object, the technical solution of the utility model is: feedwater pipe joint, comprise first fittings body and the second fittings body of working in coordination and connecting, described first fittings body front end outer wall is provided with outer wave wall, sheathed rubber pad in the trough of described outer wave wall, first fittings body front inner wall is provided with some arc grooves, elastic ring is provided with in described arc groove, seal ring is provided with between described first fittings body front end and the second fittings body front end, described second fittings body front end is provided with expansion tube, described expansion tube outer wall is provided with curve bath corresponding to the trough of some and outer wave wall, wave wall in expansion tube inwall is provided with and coordinates with outer wave wall, described curve bath is positioned at directly over the trough of outer wave wall, snap ring is provided with in curve bath, described arc groove is positioned at immediately below the trough of outer wave wall.
The internal surface of described rubber pad and the trough of outer wave wall match.
The beneficial effects of the utility model: insert on the first fittings body by the expansion tube of the second fittings body, in after expansion tube produces resiliently deformable, wave wall and outer wave wall are connected, formed multi-sealed by seal ring and rubber pad, and the elastic ring of inside outwards extrudes, and the snap ring of outside inwardly extrudes, sealing effect is very good, and installing/dismounting does not need instrument, very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the second fittings body of the present utility model.
In figure: the first fittings body 1, outer wave wall 11, arc groove 12, second fittings body 2, expansion tube 21, curve bath 22, interior wave wall 23, seal ring 3, elastic ring 4, rubber pad 5, snap ring 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, feedwater pipe joint, comprise first fittings body 1 and second fittings body 2 of working in coordination and connecting, described first fittings body 1 front end outer wall is provided with outer wave wall 11, sheathed rubber pad 5 in the trough of described outer wave wall 11, the internal surface of described rubber pad 5 and the trough of outer wave wall 11 match.
First fittings body 1 front inner wall is provided with some arc grooves 12, elastic ring 4 is provided with in described arc groove 12, seal ring 3 is provided with between described first fittings body 1 front end and the second fittings body 2 front end, described second fittings body 2 front end is provided with expansion tube 21, the curve bath 22 that the trough that described expansion tube 21 outer wall is provided with some and outer wave wall 11 is corresponding, wave wall 23 in expansion tube 21 inwall is provided with and coordinates with outer wave wall 11, described curve bath 22 is positioned at directly over the trough of outer wave wall 11, snap ring 6 is provided with in curve bath 22, described arc groove 12 is positioned at immediately below the trough of outer wave wall 11.
During installation, the second fittings body 2 is inserted the first fittings body 1 until the second fittings body 2 front end compresses seal ring 3 form first sealing.
Insert in the process of the first fittings body 1 at expansion tube 21, expansion tube 21 produces resiliently deformable, make interior wave wall 23 can cross outer wave wall 11 smoothly and fix, now interior wave wall 23 and outer wave wall 11 crimp and are crimped with rubber pad 5 mutually, formation second seals, at rubber pad 5 periphery crimping snap ring 6, and extruded by elastic ring 4 in rubber pad 5 inner ring, make to crimp between interior wave wall 23 and outer wave wall 11 tightr, good seal performance, do not need instrument just can complete during installing/dismounting, very convenient.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
