Abstract
The utility model relates to an oxygen poor protector for heating equipment, which uses gas or liquefied petroleum gas as fuel. The oxygen poor device contains a bracket, an inflame needle, an flame guide tube, a nozzle and a front probe, wherein, the inflame needle, the flame guide tube and the front probe are positioned on the bracket; the nozzle is connected to the flame guide tube; the tie line of the front probe and a control device has a resistant wire; and the inner center of the flame guide tube has a heave structure. The resistant wire of the connection wire is used for amplifying signals, which enlarges electric potential difference, so as to enhance the delicacy of the oxygen protector; in addition, the heave in the inner center of the flame guide tube is favorable to stably output the mixture of air and gas, thus flame is stable.
Description
Technical field
It is the firing equipment anoxia protection arrangement of fuel that the utility model relates to natural gas or liquefied petroleum gas.
Background technology
Anoxia protection arrangement (Oxygen Depletion System) is the requisite safety device of fuel gas heating apparatus.The operation principle of this protective device is: when fuel gas supply amount and oxygen-supplying amount relative equilibrium, the flame combustion temperature also is relatively-stationary, and along with airborne oxygen content reduces, flame temperature also will progressively reduce.When the oxygen content in the environment progressively is depleted to degree of danger owing to fuel gas buring; the flame temperature of ever-burning flame also will drop to a relative temperature; at this moment temperature is set at the temperature of anoxic point; if thermocouple records the temperature of Chang Minghuo flame when reaching this set point temperatures; it is not enough to regard as airborne oxygen content, and protective device will move automatically and cut off lights path.
The important indicator of weighing the anoxia protection arrangement performance is that oxygen content is changed and the sensitivity of the variations in temperature identification that causes; i.e. oxygen content deficiency in air; when the flame combustion temperature reduced, thermocouple can in time sense the reduction of temperature, signal is amplified and is transferred to control device.Improve the sensitivity of the startup of anoxia protection arrangement, can guarantee the healthy and life security of protection people in the Gas appliance use.
