Balanced-flow gas safety valve
A gas line limiter valve is preferably built into a stiffener used to connect gas lines. The valve includes a through-passage having a large bore and a small bore downstream from the large bore, with a conical valve seat between. A central reservoir may be disposed between the large and small bores....

| description | A gas line limiter valve is preferably built into a stiffener used to connect gas lines. The valve includes a through-passage having a large bore and a small bore downstream from the large bore, with a conical valve seat between. A central reservoir may be disposed between the large and small bores. A movable float includes a piston disposed within the large bore, a stem disposed within the small bore, and a popper to seal against the valve seat when the float is moved downstream. A coil spring urges the float upstream. The stem and the piston are cylindrical. The piston and large bore form a first orifice, and the stem and small bore form a second orifice. With the second orifice being smaller than the first, the second orifice and the buffer gas inside the reservoir create a resistance to the valve closing during sudden temporary drops in the downstream pressure. |
