AI Technical Summary

Technical Problem

In existing gas supply systems, a sudden increase in internal pressure in the gas supply pipe can damage the equipment, especially when the gas tank is frequently replaced, which exacerbates the damage to the pressure reducing valve.

Method used

By introducing an automatic shut-off valve and controller into the gas supply system, the amount of push rod pressure is controlled to regulate the gas flow rate, ensuring that the increase rate of pressure in the gas supply pipe does not exceed the specified upper limit. The gas flow path is controlled by a flow regulating valve or flow regulating structure to avoid a sharp rise in internal pressure.

Benefits of technology

It effectively protects pressure reducing valves and other devices, preventing damage caused by a rapid increase in internal pressure, and ensuring a stable gas supply.

Abstract

The present application aims to suppress a rapid increase in the internal pressure of a gas supply pipe that guides gas from a gas tank to a gas using device. The gas supply system includes: a gas tank having an automatic shut valve that opens when a push rod is pressed in and closes when the push rod is pulled out; a gas supply pipe that has the push rod at the front end and guides gas from the gas tank to the gas using device; an actuator that relatively advances and retreats the gas tank with respect to the push rod; and a controller that controls the actuator. The controller adjusts the amount of pressing of the push rod against the automatic shut valve so that, when the automatic shut valve is opened by pressing the push rod against the automatic shut valve by the actuator, the rate of increase in the internal pressure of the gas supply pipe does not exceed a prescribed upper limit value of the rate of increase.
