AUTOMATIC GAS-DISTRIBUTING STATION Russian patent published in 2020 - IPC F17D1/04 

FIELD: gas industry.

SUBSTANCE: automatic gas-distributing station (AGDS) containing a gas preparation module, comprising a high-pressure line, divided into two lines with filters of a cleaning unit, heat exchangers of gas heating units and reduction units, a low-pressure line with a module of gas commercial accounting and an odorisation unit, wherein in the low pressure line behind the reduction module there is a unit for protection against excess pressure of gas by means of gas release to the plug in a three-way valve and two safety valves. Each safety valve consists of a piston valve to release gas from the low pressure line to the plug, the piston valve forms two cavities: a constant pressure cavity and a spring cavity, wherein the constant pressure cavity is directly connected to the line behind the constant pressure valve, and spring cavity through electropneumatic valve can be communicated either with output of piston valve by candle, or with command output from amplifier.

EFFECT: technical solutions for units and AGDS generally reduce the scope of maintenance and repair procedures with increasing periodicity thereof.
