AI Technical Summary
Technical Problem
The existing dome valve cannot be automatically reset when the air source cannot supply air, and requires manual intervention, which increases maintenance complexity and workload.
Method used
An automatic reset dome valve is designed, using an action cylinder, a positioning coupling, a semi-spherical valve core, a rubber seal ring and an air-circuit auxiliary system. The gas-circuit auxiliary system automatically controls the inflation of the rubber seal ring to achieve automatic reset of the valve.
Benefits of technology
In the event of gas source failure, it can automatically reset without manual intervention, quickly restore the gas source gas supply, reduce production interruption time, improve work efficiency, and achieve accurate material transportation.

Abstract
The utility model relates to the technical field of valves, in particular to an automatic reset dome valve which comprises a dome valve body, an action air cylinder is arranged on one side of the dome valve body, the action air cylinder is connected with the dome valve body through a positioning connecting shaft sleeve, a hemispherical valve element is movably arranged in the dome valve body, and the hemispherical valve element is connected with the dome valve body through a positioning connecting shaft sleeve. The side, away from the action air cylinder, of the positioning connecting shaft sleeve extends into the dome valve body to be connected with a hemispherical valve element, rubber sealing rings are arranged at the top of the dome valve body and evenly arranged at the top of the hemispherical valve element in a surrounding mode, the rubber sealing rings are outwards communicated with air guide pipes, the air guide pipes are connected with a quick exhaust valve, and the air path auxiliary system is connected with an air guide system. The air guide system is arranged on the side edge of the positioning connecting shaft sleeve. When a fault occurs and air supply cannot be realized, the system can be automatically reset through an air path auxiliary system, manual intervention is not needed, air supply of an air source is quickly recovered, the production interruption time is shortened, and the working efficiency is improved.
