METHOD OF CONNECTING DEVICE FOR CHECKING ADJUSTMENT AND ADJUSTMENT OF SAFETY VALVES Russian patent published in 2024 - IPC F16K29/00 F16K37/00 

FIELD: gas industry.

SUBSTANCE: invention relates to the technology of checking the setting and adjustment of safety valves at gas distribution stations (GDS). Method of connecting a device for checking the setting and adjustment of safety valves consists in the fact that gas for checking the setting of the safety valve is supplied with the required increased outlet pressure from the inlet high-pressure pipeline of the GDS to the inlet of the safety valve of the safety valve unit through the device for checking the setting and adjustment of the safety valves. Device for checking the setting and adjustment of safety valves, consisting of a high-pressure reducer with pressure gauges, connected to the housing, on which a pressure gauge with a control pointer is installed, is connected to the inlet pipeline of the GDS by means of an inlet portable pipeline through a gas bleed valve, and due to the outlet portable pipeline it is connected by means of a ball valve to the input of the safety valve through a spacer, which is an annular chamber with inlet and outlet flanges, with welded side union, installed between inlet flange of safety valve and outlet branch pipe of switching device.

EFFECT: invention is aimed at increasing accuracy and reducing labour intensity of works on checking and adjusting safety valves.
