Pressure limiting valve of water feed, used e.g. in water heaters

When the pressure in the chamber (C1) is greater than a predetermined level, the valve (5) opens to feed the water into the chamber (C3) which builds up a pressure on the back of the diaphragm (M2). This forces the mushroom head (7) forward against the resistance of the spring (R) which drives the plunger (8) against the membrane (M1) thus forcing it against the seat (12) and cutting off the water flow. When the pressure in the chamber (C1) is restored to normal, the water in the chamber (C3) is evacuated via. the escape valve (14).

ABSTRACT OF THE DISCLOSURE A back pressure regulator for regulating fluid flow includes a casing the interior of which is divided into a control chamber and a flow chamber. A fluid, for example a gas, is introduced into the control chamber at a pressure equal to the control pressure, such pressure being adjustable by a piston slidably mounted in the control chamber. Fluid, under the pressure to be controlled, is introduced against the other side of the diaphragm. At the same time, fluid, the pressure of which is to be controlled, passes through a valve in the casing, the valve being slidably mounted in the flow chamber and connected to the diaphragm for movement therewith. Changes in pressure on the flow chamber side of the diaphragm result in movement of the diaphragm to open or close the valve, whereby the pressure of fluid passing through the valve is maintained constant.

9151. Wilson, G. April 12. Pressure-regulating valves; valves closing with rush of fluid; pressure-relieving devices for fluids.-A combined gas governor and automatic safety gas cut-off is arranged so that, as the pressure rises in the outlet, one valve tends to close the port, while, when the pressure falls, another valve tends to close the same port. The valves E<1>, E<2>, E<3>, E<4> mounted on the spindle Fare controlled by a diaphragm D, which takes up its load L only after rising beyond a predetermined point. The weights are supported by a hollow stud G, which also serves as a guide to the valve spindle and a vent passage to the diaphragm chamber C<1>. A bypass is arranged between the inlet and outlet so that, when a leak at the outlet side has been stopped, the pressure in the outlet again rises until the valve opens. In Figs. 1 and 2, the by-pass is shown in the valve spindle, and in Fig. 1 surrounding a spindle-guide M. A safety liquid seal 0, Fig. 3, may be connected by a pipe R to the vent opening C<4> and to the valve outlet through a pipe o<2> dipping into mercury. Any undue pressure in the outlet is relieved through the seal and produces a pressure above the diaphragm tending to close the valve, the released gas gradually escaping to atmosphere through a restricted orifice Q<2>. The diaphragm may be replaced by a bell, the weight loading by spring loading, or the lift valves by sliding or piston valves.

Suction power regulation for vacuum drying processes
