摘要：A valve assembly with low gas level signaling and controlling function includes aprimary valve threadedly engaged with an outlet of a tank, the primary valve beingformed with a recess in which is fitted a plunger having an upper end extending upwardly
through the primary valve to engage with a knob, a low level linking device comprising atubular tube connected with a bottom of the primary valve, a flexible rod having an endextending upwardly through the tubular tube to connect with the primary valve andanother end connected with an end of a float rod, and a float connected with anotherend of the float rod, and a release rod connected a pusher which is operatively
connected with the primary valve so that when the release rod is turned, the pusher willmove down the flexible rod to open the primary valve, whereby the valve assembly candetect the amount of gas remaining in a gas tank and will close when the level hasdecreased to a certain level thereby alerting the users and enabling them to replenishtheir gas supplies before all gas has been exhausted in the present gas tank, and in themeantime the user may use a release valve to release the closed valve and use theremaining gas.
