VALVE THROTTLE COMPARTMENT CLOSING METHOD Russian patent published in 2023 - IPC F16K47/08 B25B27/24 

FIELD: oil and gas industry.

SUBSTANCE: maintenance of systems for controlling the flow of gaseous and liquid products. Invention relates to throttle valves and can be used at enterprises that manufacture throttle valves and in their places of operation, for closing the compartments of the throttle valve body with the resistance of the spring block protruding relative to the first thread of the seat. A clamping device is installed on the pipeline near the throttle valve, which presses the plug against the first thread of the seat located in the compartment of the valve-throttle body, with a force that overcomes the resistance of the spring unit located in the aforementioned compartment of the valve-throttle body, until pressing the first thread of the plug to the first thread of the aforementioned seat, after which the plug is screwed into the aforementioned compartment of the valve-throttle body by means of an installation tool.

EFFECT: closing of the throttle valve compartment under the action of the spring block on the plug, ensuring the coaxiality of the plug relative to the valve-throttle body compartment, ensuring the safety of the threads of the plug, ensuring the safety of the threads of the seat in the compartment of the valve-throttle body.
