Abstract
Described is a system for remotely detecting and signalling the open and/or closed state of the shutter (O) of an element (3) for controlling the flow of gas along a gas distribution line (2), comprising an electric switch (17; 18) configured to generate an electrical signal representing at least one of the open and closed states.
Claims11
A system for remotely detecting and signaling the open and/or closed state of a shutter of an element for controlling the flow of gas along a gas distribution line, comprising:
- an electric switch configured to generate an electrical signal representing at least one of the open and closed states,
- a pneumatic detecting device supporting the electric switch and comprising a body which is movable inside it, designed to reach at least an end conditioning position of the electric switch at which the switch generates the electrical signal,
- means for remotely transmitting the electrical signal,
- an element for controlling the control element, pneumatic connection means configured for connecting the pneumatic detecting device at least to the control element.
1 more element
A unit for controlling the flow of gas, comprising:
- a gas distribution line, and
- an element for controlling the flow of gas along the distribution line, the element having a respective shutter designed to at least partly close the passage of the gas along the line,
- and further comprising a system for remotely detecting and signaling the open and/or closed state of a shutter, wherein the system includes:
- an electric switch configured to generate an electrical signal representing at least one of the open and closed states;
- a pneumatic detecting device supporting the electric switch and comprising a body which is movable inside it and designed to reach at least an end conditioning position of the electric switch at which the switch generates the electrical signal;
- means for remotely transmitting the electrical signal;
- and
- an element for controlling the control element;
- and
- pneumatic connection means configured for connecting the pneumatic detecting device at least to the control element.
