Abstract

A gas purge valve (114A-D) is provided within a fluid system, the valve being configured with one or more sensors (134B) each for sensing and generating one or more signals indicative of parameters associated with the valve. The fluid system further comprises a power source and a transmitting system for transmitting signals from the sensors to a remote control station (130).

Claims

1. A gas purge valve comprising:

a housing that defines an internal cavity comprising a flow chamber, a control chamber, and a rigid wall portion disposed therebetween, the wall portion being disposed inside the internal cavity and comprising a first side facing the flow chamber and an opposite second side facing the control chamber, the flow chamber having an inlet and an outlet;

a first one or more sensors disposed wholly within the flow chamber and being acted upon by a fluid within the flow chamber, the first one or more sensors each for sensing and generating a first one or more signals indicative of parameters associated with the fluid within the flow chamber of the valve and a fluid line coupled to the valve;

a second one or more sensors for sensing and generating a second one or more signals indicative of parameters associated with surroundings of the valve; and

an electronic circuitry disposed inside of the control chamber and integrated within the housing, the electronic circuitry comprising a power source, a processor, and a transmitting/receiving system comprising at least one antenna, the transmitting/receiving system configured for;

transmitting the first and the second one or more signals to a remote control station via the at least one antenna,

receiving valve signals from a second valve in line,

transmitting the valve signals received from the second valve in line to a third valve in line or to the remote control station,

receiving one or more control signals from the remote control station, and

transmitting the one of more control signals to the second valve.

2. A fluid system comprising a fluid line fitted with at least one gas purge valve of claim 1.

3. The fluid system according to claim 2, comprising at least one processor unit for receiving and processing the first and the second one or more signals, generating said one or more control signals which in turn operate various parameters of the valve, and transmitting said one or more control signals to the valve.

4. The fluid system according to claim 3, wherein said one or more control signals are configured for activating flow governing mechanisms of the valve to thereby open and close one or more fluid ports to the valve.

5. The gas purge valve according to claim 1, wherein said wall portion is substantially flat.

6. A method for monitoring fluid flow through a fluid system comprising a fluid line fitted with at least one gas purge valve comprising:

a housing;

a first one or more sensors disposed within the housing, the first one or more sensors each for sensing and generating a first one or more signals indicative of parameters associated with a fluid within the flow chamber of the valve and the fluid line;

a second one or more sensors for sensing and generating a second one or more signals indicative of parameters associated with surroundings of the valve;

a power source and a transmitting/receiving system for transmitting said first and second one or more signals to a remote control station via at least one antenna, wherein an electronic circuitry of the valve comprising the power source, a processor, the at least one antenna, and the transmitting/receiving system, is integrated within the housing;

the method comprising steps of;

generating the first and second one or more signals by the sensors;

transmitting the first and second one or more signals to the remote control station;

receiving valve signals from a second valve in line;

transmitting the valve signals received from the second valve in line to a third valve in line or to the remote control station;

receiving one or more control signals from the remote control station; and

transmitting the one or more control signals to the second valve,

wherein the housing defines an internal cavity comprising a flow chamber, a control chamber and a rigid wall portion disposed therebetween, the wall portion being disposed inside the internal cavity and comprising a first side facing the flow chamber and an opposite second side facing the control chamber, the flow chamber having an inlet and an outlet;

wherein the first one or more sensors are disposed wholly within the flow chamber and acted upon by the fluid within the flow chamber; and

wherein the electronic circuitry is disposed within the control chamber.

7. The method according to claim 6, further comprising:

receiving and processing the first and the second one or more signals at the remote control station;

generating said one or more control signals which in turn operate various parameters of the valve;

transmitting from the remote control station the one or more control signals to the valve; and

controlling fluid flow through the fluid system based on the one or more control signals.

8. The method according to claim 6, wherein said wall portion is substantially flat.

9. A gas purge valve comprising:

a valve housing defining an internal cavity comprising a flow chamber, a control chamber and a rigid wall portion disposed therebetween, the flow chamber having an inlet and an outlet;

a first one or more valve sensors disposed wholly within the flow chamber and being acted upon by a fluid within the flow chamber, the first one or more valve sensors each configured or arranged for sensing and generating a first one or more valve signals indicative of parameters associated with the fluid within the flow chamber valve and with a fluid line coupled to the valve;
