The invention provides a sulfur hexafluoride air chamber valve connector. The sulfur hexafluoride air chamber valve connector comprises an air chamber connecting bin, a circular hoop, a converting connecting head, a gas hose, a fixing pressure plate, a sealing gasket, a pressure release centre and a pressure releasing button, and the gas hose communicates with the air chamber connecting bin through the converting connecting head. The end, away from the converting connecting head, of the air chamber connecting bin is provided with the circular hoop, the sealing gasket and the pressure release centre are arranged in the circumference of the circular hoop, and the pressure release centre is located in the center of the sealing gasket. The pressure releasing centre and the center line of the converting connecting head are located on the same straight line, the circumference of the circular hoop is further provided with the pressure fixing plate, and the pressure releasing chamber button isarranged on the peripheral wall of the air chamber connecting bin. The sulfur hexafluoride air chamber valve connector is connected between a sulfur hexafluoride air chamber and an instrument or inflating equipment, sealing is good, and the problems that tools are frequently inserted and pulled in operation and operation is often interrupted are solved.
