Abstract
The utility model relates to a cutting ferrule type seal joint which is a pipe joint used for copper pipes. The cutting ferrule type seal joint is composed of a joint body, an outer sleeve nut, and a cutting ferrule. The joint body and the outer sleeve nut are in thread engagement, and the cutting ferrule is positioned between the joint body and the outer sleeve nut. The cutting ferrule type seal joint is characterized in that an inner wall on the connection end of the joint body is provided with a lug boss and is formed with an end surface. The cutting ferrule type seal joint is used for aluminum pipes, copper pipes, or other pipes of air conditioning pipes, etc.
Description
The utility model relates to pipe joint, refers in particular to a kind of seal connector that is used for air-conditioning duct, and the pipeline that also can be used for other copper tube, aluminum pipe connects.
Existing FERRULETYPE sealed type joint is mainly used in the steel pipe road and connects, cap nut, cutting ferrule and fittings body are arranged, steel pipe inserts fittings body during use, tighten cap nut, cutting edge on the cutting ferrule embeds outer wall of steel pipe, forms peripheral sealing surface, and cutting ferrule external diameter, the fittings body conical surface also form one linear sealing simultaneously, like this, be generally the sealing of two roads.But this structure is still not ideal enough for being tightly connected of copper tube, aluminum pipe.
The purpose of this utility model is that existing FERRULETYPE SEALING FITTING is made improvements, and makes it to increase sealing, and design provides a kind of FERRULETYPE SEALING FITTING that is applicable to copper tube, aluminum pipe.
The purpose of this utility model is achieved in that the FERRULETYPE SEALING FITTING, form by fittings body, cap nut and cutting ferrule, fittings body and cap nut are thread engagement, and cutting ferrule is therebetween, it is characterized in that: be provided with boss and form end face in fittings body connecting end inwall.
Above-mentioned design except that keeping original sealing, has increased end face seal, copper tube, aluminum pipe is connected reached the effect that increases sealing.
Below by drawings and Examples the utility model is described further again.
Shape organigram when Fig. 1 is used in combination for the utility model;
Fig. 2 is the utility model fittings body shape organigram;
Fig. 3 is the utility model cap nut shape organigram;
As shown in the figure, the utility model is made up of fittings body 1, cap nut 2 and cutting ferrule 3, fittings body 1 is a thread engagement with cap nut 2, and cutting ferrule 3 is therebetween, after pipe fitting 4 inserts fittings body 1, tighten cap nut 2, be provided with boss and form end face 5 in fittings body 1 connecting end inwall, so after pipe fitting 4 inserts, form the end face contact, not only play the end face seal effect, also can play position-limiting action.And utilize the distortion of tubing, and can be further and the degree that fits tightly of all and pipe fitting 4 surface of contact, improve the reliability of sealing greatly.In addition, be provided with boss 6 and form a ring in an end of cap nut 2, with further assurance be tightly connected pipeline straightness accuracy and with the coaxality of fittings body, the axial length of this boss 6 is 5～20mm.Adopt the utility model in split-type air conditioner through test, can solve the chronic disease of freon leakage, as seen its sealing is practical effectively reliable.
