Description

90 ° of hose couplings of band nut bending
Technical field
The utility model relates to a kind of hose coupling, specifically is 90 ° of hose couplings of a kind of band nut bending.
Background technique
90 ° of hose couplings of band nut bending on the market are mainly used in the conveying of oil, gas, water etc. at present, it comprises the joint body of hollow, described joint body is formed by connecting by first body and second body, described first body and the formed angle of second body are 90 °, promptly form by after 90 ° of second body or first body bendings.One end of described joint body be provided with one with joint body axial limiting and the nut that circumferentially rotates, described nut is used for being connected with threaded pipe; The other end of described joint body is provided with the ring joint that is connected with flexible pipe, and described nut is a hexagon nut.There is following defective in 90 ° of hose couplings of band nut bending of said structure in the using process of reality:
1, because 90 ° of hose couplings of the band nut of prior art bending use is hexagon nut, the hexagonal configuration of this nut approaches circle, therefore in the process of using spanner to turn, easily produce slide relative between this hexagon nut and the spanner, thereby cause joint to damage.
2, only rely on screw thread to seal between 90 ° of hose couplings of the band nut of prior art bending and the threaded pipe, its sealing is relatively poor, therefore this hose coupling is easy to produce in the using process of reality and leaks, thereby makes the functional reliability of prior art hose coupling reduce.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides the band nut bending that is difficult for producing slide relative between a kind of nut and the spanner and is difficult for taking place leaking 90 ° of hose couplings.
The technical solution of the utility model is, provide a kind of band nut bending 90 ° of hose couplings, the joint body that comprises hollow, described joint body is formed by connecting by first body and second body, and described first body and the formed angle of second body are 90 °; One end of described joint body be provided with one with joint body axial limiting and the nut that circumferentially rotates, the other end of described joint body is provided with the ring joint that is connected with flexible pipe, described nut is five jiaos of nuts; Described joint body is a conical surface near the outer surface of nut one end, and it is 36 °~38 ° that described conical surface extends formed cone angle a, and described cone angle a is positioned at outside the joint body.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, the nut in the utility model is five jiaos of nuts, this nut is compared with the hexagon nut of prior art, its shape is kept off in circle, therefore in the process of using spanner to turn, be difficult for producing slide relative between these five jiaos of nuts and the spanner, make this joint not fragile, thereby guaranteed the working life of this hose coupling.
2, the joint body of the utility model hose coupling is a conical surface near the outer surface of outside thread one end, it is 36 °~38 ° that conical surface extends formed cone angle a, cone angle a is positioned at outside the joint body, this joint not only can rely on screw thread to seal, and can on threaded pipe, process the conical surface that matches with this conical surface, utilize two cooperatively interacting of the conical surface and seal its better tightness.Therefore this joint is difficult for producing in the using process of reality leaking, thereby has guaranteed the functional reliability of the utility model hose coupling.
As improvement, described joint body is provided with an annular groove near the outer surface of five jiaos of nut one ends, the internal surface of described five jiaos of nut one ends is provided with the annular lug that matches with the annular groove size shape, described annular lug axial limiting and circumferential the rotation in annular groove.The utility model hose coupling utilize annular groove and annular lug come five jiaos of nuts are carried out spacing, its good limit effect.
As improvement, described cone angle a is 37 °, and the sealing effect of two conical surfaces that utilizes into this cone angle is better, its more difficult leakage.
