ABSTRACT:
A gas control valve includes a bore and a room formed in the upper portion and lower portion and includes a valve seat formed between the hole and the room, and includes an inlet and an outlet pathway. A plate is slidably engaged in the room and has two posts slidably engaged in the body. A ball member is supported on the plate for engaging with the valve seat so as to block the passagewayu from the room to the bore. A rod is slidably engaged in the bore for disengaging the ball member from the valve seat. The ball member is forced to engage with the valve seat in order to block the gas passageway so as to prevent the gas from flowing through the outlet pathway when the gas has a pressure large enough to force the ball member to engage with the valve seat. The plate may be adjusted relative to the valve seat in order to adjust the distance between the ball member and the valve seat.
