Pipe fitting quick change connection set described in the utility model, comprise male end and female end, described male end and female end respectively comprises a tubular configured joint and the pressing plate that is used for fixing bolt of fixedlying connected with the tubular configured joint outer peripheral surface, wherein tubular configured joint one end of male end is provided with male cone (strobilus masculinus), and tubular configured joint one end of female end is provided with the inner conical surface with the identical cone angle of male end joint; Male end and female end adopts cone match to connect, and uses bolt, and the sealing of O RunddichtringO is adopted in conical surface junction.Male end and female end adopts cone match to connect, and the installation time can effectively be saved rapidly in the location during installation.Adopt the O RunddichtringO sealing of specific rubber material, both high temperature resistant, sealing effect, the O RunddichtringO is positioned in the middle of the conical surface, does not contact with fed sheet of a media, can not be corroded, and has improved the working life of O RunddichtringO.
Further, the pressing plate of described male end is provided with at least two U-shaped mouths, and U-shaped mouth two parallel edges are provided with otic placode, and described otic placode is provided with lockhole; The pressing plate of described female end is provided with at least two U-shaped mouths, and wherein the angle of two adjacent U-shaped mouth center lines is identical with the angle of male end U-shaped mouth center line; Described two pressing plates are provided with stiffening rib.In order to guarantee soundness, can be with the otic placode and the moulding of pressing plate integral production of male end.Two pressing plates strengthen the locking degree of pressing plate by center master's material and the moulding of stiffening rib integrally casting.The pressing plate diameter of male end and female end is identical, and the corresponding setting of the quantity of U-shaped mouth and position.
Further, it is fixedly connected that described male end and female end adopts swing bolt.The through hole of swing bolt is put between the otic placode of male end, and fixedlys connected with otic placode with cotter pin by bearing pin with holes, threaded end is put in the U-shaped mouth of female end, and fixes with hexagon nut, places spring washer between nut and pressing plate, guarantees soundness.Because of the employing swing bolt connects, and the negligible amounts that uses, both saved the installing/dismounting time, guaranteed the soundness that connects again, improved safety coefficient.
The conical surface cone angle of described tubular configured joint is 5 °-40 °.
Preferably, the conical surface cone angle of described tubular configured joint is 30 °.
Further, described male end and female end adopts metallic material to make, and is preferred, adopts stainless steel to make, and improved anti-pressure ability, prolonged the working life of connection set.
Quick change connection set described in the utility model adopts cone match to connect, and can locate rapidly during installation, has saved the installation time, and has had good sealing property; The employing swing bolt is fixed, and is for convenience detach, improved the resistance to pressure of connection set, prolonged working life, is applicable to the connection between the pipeline that needs fast assembling-disassembling, especially is fit to the fast assembling-disassembling of oxygen rifle and pipeline.
