Gas valve capable of switching for two different gas supplies

摘要

A gas valve capable of switching for two different gas supplies, has two outlets, two independent rotation positioning areas and two staggered groups of fire holes, one outlet responds to the first gas supply, and the other outlet corresponds to a second gas supply; when the gas valve is mounted on a stove, each outlet is connected to the gas nozzle fit for the corresponding gas supply, then when the corresponding gas supply is used, only the valve rod is switched to the corresponding rotating positioning area, the rotating positioning area corresponds to the corresponding group of fire holes and outlet, only the outlet fit for the gas supply supplies gas to the stove at the moment, and the other outlet is in a closed state all the time, so the gas valve capable of switching for two different gas supplies can be realized without replacing the gas nozzles.

主权项

1. A gas valve capable of switching for two different gas supplies, comprising:
a valve body having a top end, an inlet, a first outlet and a second outlet; a valve core rotatably disposed inside the valve body, having a peripheral surface and a first group of fire holes and a second group of fire holes disposed thereon; a valve cover connected to the top end of the valve body, the valve cover having a center passage and an inner chamber with a first step and a second step; a rotatable valve rod for driving the valve core, the rotatable valve rod being inserted into the center passage of the valve cover, the rotatable valve rod having a protrusion extending away from the valve rod; a regulator with a rear end adjustably inserted into the inner chamber of the valve cover and the valve body, the regulator being able to adjust position of the protrusion; wherein, the inlet in communication with the first outlet through the first group of fire holes, and the inlet also in communication with the second outlet through the second group of fire holes; the first step and the second step in the inner chamber of the valve cover limit rotation of the protrusion; a first rotation positioning area is defined between the regulator and the first step, when the protrusion is inside the first rotation area, the first group of fire holes are in communication with the first outlet, and the second group of fire holes are not in communication with the second outlet; a second rotation positioning area is defined between the regulator and the second step, when the protrusion is in the second rotation area, the second group of fire holes are in communication with the second outlet, and the first group of fire holes are not in communication with the first outlet; when the regulator moves upward and the rear end of the regulator moves out of the inner chamber of the valve cover, the protrusion can move between both the first rotation positioning area and the second rotation positioning area.
