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, 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, and provide a kind of feedwater pipe joint, good seal performance, installing/dismounting is quick.
For achieving the above object, the technical solution of the utility model is: a kind of feedwater pipe joint, comprise first fittings body and the second fittings body of working in coordination and connecting, described first fittings body front end is provided with expansion tube, the anterior outer wall of described second fittings body is provided with flange, sealing gasket is provided with between described first fittings body and the second fittings body, described sealing gasket comprises the lower longitudinal sealing pad being in turn connected into one, transverse sealing pad and upper longitudinal sealing pad, lower longitudinal sealing pad is provided with between described first fittings body front end and the second fittings body front end, longitudinal sealing pad is provided with between described expansion tube front end and flange front end portion, described transverse sealing pad laminating is located at expansion tube inwall, transverse sealing pad inwall is provided with some lip limits, described lip limit and the second fittings body front end outer wall interference fit, described expansion tube spins nut, described nut is provided with abutting part, described abutting part props up flanged rear portion.
The beneficial effects of the utility model: the lower longitudinal sealing pad arranged by integral type, transverse sealing pad and upper longitudinal sealing pad, transverse sealing pad is established some lip limits, make to define between the first fittings body and the second fittings body multiple-sealed, overall sealing performance is very good, just can installation or removal be completed by rotary nut, very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the first fittings body 1, expansion tube 11, second fittings body 2, flange 21, lower longitudinal sealing pad 3, upper longitudinal sealing pad 4, nut 5, abutting part 51, transverse sealing pad 6, lip limit 61.
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, a kind of 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 is provided with expansion tube 11, the internal diameter of expansion tube 11 is greater than the internal diameter of the first fittings body 1, the anterior outer wall of described second fittings body 2 is provided with flange 21, sealing gasket is provided with between described first fittings body 1 and the second fittings body 2, described sealing gasket comprises the lower longitudinal sealing pad 3 being in turn connected into one, transverse sealing pad 6 and upper longitudinal sealing pad 4, lower longitudinal sealing pad 3 is provided with between described first fittings body 1 front end and the second fittings body 2 front end, longitudinal sealing pad 4 is provided with between described expansion tube 11 front end and flange 21 front end, described transverse sealing pad 6 laminating is located at expansion tube 11 inwall, transverse sealing pad 6 inwall is provided with some lip limits 61, described lip limit 61 and the second fittings body 2 front end outer wall interference fit, by the lower longitudinal sealing pad 3 that integral type is arranged, transverse sealing pad 6 and upper longitudinal sealing pad 4, transverse sealing pad 6 is established some lip limits 61, lip limit 61 and the second fittings body 2 front end outer wall interference fit, make to define between the first fittings body 1 and the second fittings body 2 multiple-sealed, overall sealing performance is very good, the bearing of trend on lip limit 61 is consistent with the second fittings body 2 front end direction of insertion simultaneously, guarantee interference fit, the sealing gasket of integral type is more reliable relative to multiple sealing gasket sealabilities of blocking type.
Described expansion tube 11 spins nut 5, and described nut 5 is provided with abutting part 51, and described abutting part 51 props up flange 21 rearward end.Can complete installation by screwing in nut 5 after the first fittings body 1 and the mutual grafting of the second fittings body 2, nut 5 inwall is provided with internal thread, and expansion tube 11 outer wall is provided with the outside thread matched with internal thread.
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.
