Abstract

This article describes a gas vent leak detector which gives a visual indication of leaks in the line, thus enabling the observer to initiate immediate correction. On industrial gas burners, burning natural gas, many times the solenoid valve, shutting off the line, fails to seat properly during operation or otherwise fails to open properly. In both cases a venting line is provided to assure that explosive gases do not accumulate in an unwanted area. If a leak detector, as shown in the figure, is situated in the venting line, immediate detection of any problem can be visually detected. By utilizing the valve shown in the figure, roof discharge monitoring sniff testers can be eliminated and energy savings realized.

Gas Vent Leak Detector

This article describes a gas vent leak detector which gives a visual indication of leaks in the line, thus enabling the observer to initiate immediate correction. On industrial gas burners, burning natural gas, many times the solenoid valve, shutting off the line, fails to seat properly during operation or otherwise fails to open properly. In both cases a venting line is provided to assure that explosive gases do not accumulate in an unwanted area. If a leak detector, as shown in the figure, is situated in the venting line, immediate detection of any problem can be visually detected. By utilizing the valve shown in the figure, roof discharge monitoring sniff testers can be eliminated and energy savings realized.

The valve shown in the figure comprises a body 10 having an inlet pipe 11 at the lower end thereof and an outlet pipe 12 at the discharge end thereof. The interior of the body 10 is hollow and generally shaped in the form of a long narrow cone 16 with a smaller cone-like seat 17 provided at the lower end thereof. Within the hollow cavity 13 of the tube 10 there is provided a ping-pong ball 14 on which is inscribed easily visible crosses 15. These crosses 15 can be readily viewed through the clear lucite body 10.

In operation, even extremely low gas flow through the tube 11 causes the ball 14 to rise from the seat 17 and to rotate. This rotation of the ball 14 is readily viewed by anyone observing the ball in the cavity 13 and thus v...
