Problems solved by technology

A further problem encountered with lever actuated valves is the performance limitation caused by the arc that opens and closes the seal relative to the input port, the arc being defined between the pivot on it and the valve. determined by the length of the lever arm between
In particular, movement of the seal or valve member along an arcuate path relative to the inlet port can make it extremely difficult to obtain and maintain a reliable seal of the seal member relative to said inlet port.
Another problem with the pressure regulating valve using the lever principle is that the flow of fluid from the input port to the pressure chamber will produce turbulent flow conditions. During the operation of the valve, this turbulent flow will cause the lever arm to vibrate and / or swing to make the flow direction The gas at the user end fluctuates

Embodiment Construction

[0015] Objects and advantages of the present invention will be better understood by referring to the following description of preferred embodiments and accompanying drawings.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings. It should be clear that this is only for illustrating preferred embodiments of the present invention, and cannot limit the scope of the present invention. Figures 1-3 show a fluid pressure regulating valve 10 of the present invention comprising upper and lower housings 12 and 14, and a flexible membrane 16 clamped between the outer circumferences of the two housings, the membrane 16 enclosing the inner circumference of the housing. Partly forms a pressure chamber 18 and an outlet chamber 20 , which communicates with the surrounding atmosphere via an outlet hole 22 in the housing 12 . Said valve has an axis A to which the membrane is not only perpendicular but also coaxial with axis A; the membr...

Abstract

The invention relates to the field of fluid pressure regulating valves, in particular to an improved valve operating mechanism for a film actuated pressure regulating valve. The invention discloses a diaphragm actuated pressure regulating valve for connecting a gas source under pressure and a user end, which comprises an input port with an axis, a valve element coaxial with the input port and a valve element controlled by a diaphragm. A ball and cam valve element actuator in which the membrane is perpendicular to and coaxial with the input port.

Description

technical field [0001] The present invention relates to the field of fluid pressure regulating valves in which a valve member is actuated by a diaphragm to control the flow of fluid through the valve member. More particularly, the invention relates to an improved valve member operating mechanism for a diaphragm actuated pressure regulating valve. Background technique [0002] Fluid pressure regulators are known to operate in response to fluid pressure acting on a pliable membrane clamped between valve housing parts and forming a pressure chamber on one side of the membrane and a vent to atmosphere on the other side. cavity. The pressure chamber includes an inlet or port for fluid under pressure from a fluid source, and an outlet port for gas to flow to a consumer such as a gas heated cooking oven. A valve unit to control the flow of fluid from the input port to the outlet port, and usually, the valve unit includes a lever arm pivotally mounted in the pressure chamber and on...
