Embodiment Construction

[0012] Such as figure 1 , figure 2 shown. The slot head quick connector is composed of a fixed key 1, a blocking block 2, a sealing ring 3, a connector body 5, a movable key 8, a reed 9, and a connector body cover 7. The connector body 5 is an integral type, and a corresponding fixing keyway is provided on the inner side of the steel pipe keyway at one end, and the connector body 5 is provided with a through hole for fixing the key. The fixed key 1 is composed of an arc segment, which is respectively put into through holes of the fixed key, and then closed with a blocking block 2 . The fixed key 1 is fixedly connected to the groove head of a steel pipe, and the blocking block 2 is used to close the entrance of the fixed key 1. The connector body 5 is provided with a corresponding movable card keyway on the inner side of the steel pipe card keyway of the groove head at the other end, and the movable card keyway is evenly provided with movable card key through holes. Movabl...

Abstract

The invention relates to a slotted head fast connector belonging to the technical field of perfusion tube connectors and mainly solving the problems of mechanized laying and burglary prevention of steel pipelines. The slotted head fast connector is characterized in that two sealing rings 3 positioned at the inner side of a connector body 5 are respectively arranged on the interface position of two connected steel pipes; a fixed clip key 1 is fixedly connected with a slotted head of one steel pipe, and a stop block 2 is used for closing an inlet provided with the fixed clip key 1; a movable clip key 8 and a reed 9 are arranged between the connector body 5 and a connector body cover 7 and are used for limiting and fixing the slotted head of the other steel pipe. The invention limits the movement of the steel pipes by adopting the fixed clip key 1 and the movable clip key 8, thereby ensuring the use safety and the reliability by limiting; the slotted head fast connector can be disassembled by adopting a special tool, thereby realizing the mechanized laying of the steel perfusion pipelines; in addition, the invention has reliable work and pressure resistance more than or equal to 6.0 MPa, is mainly used for the delivery of oils (gasoline, kerosene, diesel oil, motor oil, and the like) and can be also used for the delivery of water and other non-corrosive liquids.

Description

technical field [0001] The invention belongs to the technical field of infusion tube joints. Specifically, it relates to a steel pipe groove head quick connector, which is mainly used for the connection between steel infusion pipelines. Background technique [0002] At present, the device used to connect steel infusion pipelines in China is a grooved connector. When using it, two steel pipes are butted and then put on a sealing ring, and then the grooved connector composed of two semicircular blocks is used to clamp the steel pipe. Groove heads at both ends, and then tighten the bolts. Its disadvantages are firstly that the groove head connector is fixed by bolts, which can be disassembled by ordinary tools, and the oil is easy to be stolen; When connected in the air, the slot head connector is easily broken and damaged. Contents of the invention [0003] The object of the present invention is to provide a new type of steel pipe connecting device which is easy to assemb...
