A mechanical valve assembly for the control of a gas flow to a gas appliance. The mechanical valve assembly includes at least one input knob movably connected to a housing, a shaft assembly connected to at least one input knob, and a manually-operated valve located inside the housing and in between the inlet port and the outlet port. The manually-operated valve is mechanically connected to the shaft assembly, and the manually-operated valve is configured for opening and closing a gas flow between the inlet port and the outlet port.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.

According to one embodiment a gas tap is provided that includes a manually operable shaft having a first end coupled to a regulating element and a second end configured to be coupled to a knob that can be operated by a user. The shaft includes a first locking element, and the gas tap includes a second locking element. The shaft is rotational between an initial angular position and a final angular position, and is axially movable when it is arranged in the initial angular position between a first axial position in which the first locking element and the second locking element cooperate with one another, preventing the shaft from being able to rotate, and a second axial position in which the shaft is able to rotate. The user has to pull on the shaft in order to move it from the first axial position to the second axial position.

A safety valve device in a gas burning apparatus includes a valve body and an adjusting member. The valve body has an inlet port and an outlet port and defining a receiving room disposed between the inlet port and the outlet port. The receiving room opens to and in communication with the inlet port and the outlet port. The adjusting member is received by the receiving room. The adjusting member deforms in responsive to temperature from a first shape when in a normal mode into a second shape when in a protection mode and vice versa. The adjusting member is in the normal mode when experiencing a temperature not greater than a set temperature. The adjusting member is in the protection mode when experiencing a temperature greater than the set temperature.

A gas burner includes a gas reservoir, a combustion device, and a tilt safety device fluidly connecting to one another. The tilt safety device includes first and second seats including first and second gas passages respectively, an elastomer disposed on the second seat and including a section defining a stop, a control mechanism including a lever adjacent to the elastomer and including a first contact area and at least one second contact area selectively engaging with a pusher which engages with the stop, and a gas flow channel connecting to the second gas passage and a hole extending through the elastomer and the first gas passage and including the first and second ends thereof including the stop disposed therebetween. The first and at least one second contact areas space from the elastomer at first and second heights respectively. The second height is less than the first height.

A mechanical valve assembly for the control of a gas flow to a gas appliance, the mechanical valve assembly comprising: a housing; a gas inlet port associated with the housing; a gas outlet port associated with the housing; a timer-controlled valve operable to open and close a gas flow between the inlet port and outlet port; and a manually-operated emergency shut-off valve positioned between the inlet port and the outlet port, ahead of the timer-controlled valve relative to a direction of the gas flow through the mechanical valve assembly.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner extend through the metal box and the first flame arrestor is connected to the metal box.

The present disclosure is directed to safety knobs for gas cooktops which senses the absence of flame on the burner (42) and gets switched “Off” automatically to cut-off the gas supply to the burner (42). The design of this “Safety Knob” is such that it can be retrofitted to any Gas Cooktops by simply removing the normal knob and fitting the “Safety Knob” to the Gas Cooktop. A full assembly of safety knob comprising of wheel circular spring, lever assembly, knob, thermocouple with solenoid attached to gas cooktop is presented in present disclosure that achieves safe operation on gas cooktop.

A portable flaring apparatus is disclosed. The flaring apparatus comprises a stack comprising multiple segments of varying diameters, which may be configured to be telescoped for transport. The flaring apparatus further comprises one or more inlets for the intake of gas, an arrester for suppressing flames and detonation within the flaring system, and a plurality of combustion tips for flaring gas. The components of the flaring apparatus may be affixed to a trailer platform for portability.

An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.
