A thermostatic flow control device including a safety valve and a thermostatic valve controlling flow between an inlet and main and pilot outlets in a casing, and a selector dial for moving a cam member within the casing, the safety and thermostatic valves each having an axially movable member engaging a cam surface of the cam member such that movement of the cam member provides simultaneous pilot and on-off control of the safety and thermostatic valves.

A rotary gas control apparatus has a rotary handle adapted for rotation from a gas-off position via an ignition stand-by position into a gas-on position. By the motion of the rotary handle, a piezo-electric ignition device with an impact mechanism is energized. In the ignition stand-by position, the rotary handle may be depressed, whereby a safety valve is opened and gas is allowed to flow to a pilot burner. In the depressed position, the handle is rotatable from the ignition stand-by position through a limited angle to an ingition position, whereby the ignition device is triggered and the pilot burner is lit thereby. A magnet thermoelectrically energized by the pilot burner holds the safety valve open. The handle is returned to the ignition stand-by position, moved outward and can now be rotated to the gas-on position, in which a main gas valve opens to permit the flow of gas to a main burner.

A automatic ignition gas lantern includes baffle positioned near the outside of a mantle, so that gas flowing out of the mantle will be disturbed by the baffle. This sets up a region with a fuel/air mixture that can be easily and reliably ignited. A spark is then generated in this region, which ignites the gas and causes the mantle to glow brightly.

An ignition system for combustible waste gas flares is described in which pilots and pilot igniters are employed, the air to gas ratio for pilot ignition being controlled to compensate for the combustible content of the pilot igniter gas, the pilot operation being sensed to control the ratio, controlled intermittent ignition of the pilot igniter gas being provided, with a repetitive cycle in the event of failure of ignition of the pilot igniter gas and of the pilot gas, the operating conditions being visually indicated at a control panel.
摘要:
A cock apparatus of automatic ignition type for use in a gas appliance including an ignition handle, a valve member disposed within the cock body for rotation with the turning movement of the ignition handle thereby supplying gas to a main burner and a pilot burner, and a spark generator generating sparks for igniting the pilot burner in response to the turning movement of the ignition handle. The cock comprises a rotary shaft capable of free rotation and restrained rotation relative to the valve member and normally urged by a spring to rotate in the closing direction of the valve member, and a heat sensor for sensing ignition and non-ignition of the main burner, the heat sensor being operatively connected to the rotary shaft so that the rotary shaft and the valve member can be automatically rotated in the valve closing direction by the force of the spring in the event of ignition failure of gas or accidental extinction of gas flame burning on the main burner.

A thermostatic flow control device including a safety valve and a thermostatic valve controlling flow between an inlet and main and pilot outlets in a casing, a selector dial for moving a cam member within the casing, and a lever pivotally and slidably mounted in the casing and selectively controlled by the cam member, the safety and thermostatic valves having members engaging the lever and axially movable by pivoting and sliding movement of the lever, respectively, such that movement of the selector dial provides simultaneous pilot and on-off control of the safety and thermostatic valves.

AN AUTOMATIC IGNITION SYSTEM FOR FLARING WASTE COMBUSTIBLE GASES BEING EXHAUSTED THROUGH A STACK, WHICH UTILIZES AN IGNITOR BURNER WHICH IS AUTOMATICALLY ENERGIZED WHEN GASES ARE PASSED TO THE STACK. A MAIN FLAME SCANNER, IGNITOR BURNER SCANNER, AND A TIMER ARE SO INTERRELATED THAT A SAFE, ECONOMICAL, AND EFFICIENT OPERATION IS PERFORMED.

IMPROVED METHOD AND APPARATUS TO CUT OFF THE FUEL SUPPLY TO A LIQUID OR GAS FIRED HEATER IF SUCH HEATER IS DISLODGED IN ANY MANNER FROM THE POSITION WHERE IT IS INSTALLED.
摘要:
Control means having a first passage means for interconnecting a source of fuel to a pilot burner means to produce a small standby flame at the pilot burner means, the control means having second passage means for additionally interconnecting the source of fuel to the pilot burner means to produce a large heater flame at the pilot burner means whereby no fuel is adapted to be interconnected to a main burner means when only a small standby flame exists at the pilot burner means and the source of fuel is adapted to be interconnected to the main burner means when the large heater flame exists at the pilot burner means. A single adjusting means is provided in the passage means for adjusting the fuel flow rate therethrough by substantially infinitely adjusting the flow rate through one of the passages and adjusting the flow rate through the other passage means in substantially a stepped manner.
