A mechanical valve 10 allows a liquid system to operate as normal. However, if there is an abnormally high continuous flow of liquid, a limiter 300 stops the flow. The purpose of the valve is to prevent unwanted overflows of liquid from the system, but otherwise not to interfere. The amount of liquid that can flow continuously can be preset to a predetermined level by knob 400. Tripmeter mechanism 600 detects and tracks liquid flowing through path 140 and fluid energy is used to drive the mechanism 600. After a predetermined amount of liquid flow, the mechanism 600 causes limiter 300 to stop the flow. All the mechanisms of the valve are integrated into a single unit, so that all that is needed for installation is to connect it to an inlet pipe 100 and an outlet pipe 200. |
