Abstract
The invention mainly relates to a high-pressure disconnector capable of realizing rapid pressure relief. The disconnector mainly comprises three parts including an integrated lower check valve assembly, an integrated upper check valve assembly and a three-way pressure relief assembly. When the disconnector supplies gas to a system, the lower check valve assembly is butt-jointed with a one-way pressure relief connector, after butt-joint, a handle assembly is clockwise rotated by 90 degrees (limited position), a three-way ball rod communicates an inlet with an outlet, high-pressure gas in the system is fed via the inlet and passes through the three-way ball rod and the upper check valve assembly, a valve core of the lower check valve assembly is opened, and the high-pressure gas is supplied to the system. After the gas is supplied, high-pressure gas between the valve core of the lower check valve assembly and the three-way ball rod is relieved, after pressure relief, a sliding sleeve of the upper check valve assembly is slid rightwards, a spring I is compressed until steel balls are separated from an annular groove of the lower check valve assembly, and the lower check valve assembly is separated from the upper check valve assembly. The disconnector is high in pressure (45 MPa), small in size, capable of realizing rapid connection and separation of the system under pressure and high in connection efficiency.
