Description
Technical field
The utility model relates to the pipeline connection area, especially relates to a kind of quick coupler.
Background technique
In pipe laying and installation process, often use various terminal, make the installation and laying of pipeline conveniently connect soon, but the joint of Shi Yonging all is to adopt the plain seal mode in the market, when the gas that circulates in the pipeline or fluid pressure are bigger, the pressure of joint area will increase, at this moment, often the plane sealing place of single sealing will produce leakage phenomenon, cause the working condition instability of pipeline, bury down great potential safety hazard, simultaneously, existing rapid pipe joint tends to reduce the discharge value of pipeline.
The utility model has carried out useful improvement in order to overcome above-mentioned defective.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and the quick coupler of a kind of double seal (plane sealing and interior external sealed) is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of quick coupler, comprise body, its special way is: also comprise connecting head, spring, spool, sealing gasket, No. two springs, overcoat and jump rings, the rear end of described connecting head tightly is enclosed within the front end of body, the rear end of described body is cylindrical-shaped structure, the rear end of body is socketed in the overcoat, spring and spool are installed in described connecting head and the body successively, and the endface position that connecting head contacts with body is provided with sealing gasket, described body and overcoat connection part are provided with the spring two that compresses, and described jump ring is installed in the overcoat;
Further, the tip position of the cylindrical-shaped structure of described body rear along the circumferential direction evenly is provided with some steel balls, in the middle of the described overcoat groove position is arranged, and after the assembling, described steel ball is stuck in the groove position of overcoat;
Further, a described spring is the cone screw shape, and wherein wide of a spring is to contact with connecting head, and the narrow position of a spring withstands on the spool;
Further, described No. two springs are cylindric.
The beneficial effects of the utility model: the utility model is simple in structure, adopted the double seal mode of interior external sealed peace face sealing, make spool no matter still extremely stable under high pressure and the operating on low voltage condition, simultaneously, the spool that this joint adopts lengthens than common spool, makes flow that corresponding increase also arranged.
