The utility model is characterized in that it includes an inflatable connector, a quick connector and a metal hose; the inflatable connector is connected to the metal hose through the quick connector, the metal hose is connected to the inflation decompression valve, and the inflation decompression valve is connected to the steel cylinder.

The inflation joint includes a front end connector and a tail bolt, the front end connector is connected to different SF6 equipment, and the tail bolts are of uniform size.

The quick connector includes an adapter and a self-styled male head, one end of the adapter is connected to the self-styled male head, and the other end is connected to the tail bolt.

The two ends of the metal hose are provided with self-styled female connectors, the self-styled female connector at one end is connected to the self-styled male connector of the quick connector, and the self-styled female connector at the other end is connected to the self-styled male connector connected to the inflation pressure reducing valve.

Further, a constant temperature heating device is placed on the outer periphery of the connecting pipe connecting the inflation pressure reducing valve to the steel cylinder.

Further, 4-6 kinds of booster pads with different heights are set, and they are set on the thimbles in the inflatable joint according to the needs of the SF6 equipment.

Further, a right-angle elbow is also designed to connect the tail bolts of the inflation joint.

It can be seen from the above technical scheme that the utility model is a professional joint, pipeline and instrument suitable for vacuuming, SF6 recovery, SF6 gas filling, SF6 gas detection, etc. Advanced tools and appliances can greatly improve the working time of personnel and enhance the professional level of staff; reduce the time for on-site preparation work and ensure the safety and production efficiency of the power grid; reduce the type and quantity of on-site inflatable pipelines.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in FIG. 1 , the utility model includes an inflatable connector 1 , a quick connector 2 and a metal hose 3 . The inflation connector 1 is connected to the metal hose 3 through the quick connector 2, the metal hose 3 is connected to the inflation pressure relief valve 4, and the inflation pressure relief valve 4 is connected to the steel cylinder 5.

As shown in FIG. 3 , the inflation joint 1 includes a front connection head 11 and a tail bolt 12 . The utility model corresponds to different SF6 equipments through the front end connector 11, and connects different SF6 equipments, and the tail bolts 12 are of uniform size. In this way, there is no need for a variety of adapters or pipes to be connected, and only one specification, that is, a uniform size of tail bolts, can be conveniently connected.

The quick connector 2 includes an adapter 21 and a self-styled male head 22 . FIG. 4 is a schematic structural view of the adapter 21 , and FIG. 5 is a structural schematic view of the self-styled male head 22 .
