摘要:
A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular nature of the apparatus allows for convenient expansion or modification of the manifold assembly to suit any application that comprises a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module in an example can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is readily expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

A valve (30) to be used when blowing air into squeezing pads (12) from a high pressure blower (32), such as a side duct blower, said valve (30) comprising a valve chamber (40) comprising a primary set of openings with a first opening (42) connected to said high pressure blower and a second opening (44) connected to said squeezing pads, whereby air can be transferred through said valve chamber between said squeezing pads and said high pressure blower, said valve chamber further comprising a third opening (46), whereby air from said first opening can pass through said third opening, and where air not passing through said third opening passes through said second opening, said valve further comprising a valve spool for blocking (48) said third opening and thereby changing the amount of air passing through said third opening. The valve spool for blocking said third opening comprises a limiter element (49, 1101), wherein said limiter element and/or said third opening (46, 1103) has a varying diameter along its longitudinal axis (47), where the limiter element is adapted to be inserted along its longitudinal axis in said third opening, and where the extent of insertion of said limiter element changes the amount of air passing through said third opening. The invention further relates to a lift head with the above valve.

摘要:
An integrated flow control and flow measurement apparatus includes a body; a flow bore which extends through the body; a closure member which is positioned in the body and is movable between an open position in which a fluid is allowed to flow through the flow bore and a closed position in which the fluid is prevented from flowing through the flow bore; and a flow sensor which is operatively connected to the flow bore. When the closure member is in the open position, the flow sensor is operable to generate a signal from which a flow rate of the fluid through the flow bore is determinable.
