Abstract
The utility model discloses an infrared dual-gas type fireplace. The infrared dual-gas type fireplace is characterized by comprising a natural gas pressure maintaining valve and a liquefied gas pressure maintaining valve, wherein the natural gas pressure maintaining valve is externally connected with natural gas; the liquefied gas pressure maintaining valve is externally connected with liquefied gas; the natural gas pressure maintaining valve and the liquefied gas pressure maintaining valve are respectively connected with a main control valve through a check valve; the other end of the main control valve is connected with a natural gas nozzle and a liquefied gas nozzle; the other end of the natural gas nozzle and the other end of the liquefied gas nozzle are connected with an infrared burner; and an extinguish safe protection device is also connected to the main control valve. Two or more than two gas sources can be used in the infrared dual-gas type fireplace; because the natural gas pressure maintaining valve externally connected with the natural gas and the liquefied gas pressure maintaining valve externally connected with the liquefied gas are connected with the main control valve through the check valve, so the gas sources flow in a fixed direction, and backflow and gas leakage are not caused; and the infrared burner is adopted, and the central lines of two nozzles derivate from the central line of an ejector tube, so the gas jetted from each nozzle can be fully burnt, and the gas sources are saved. The infrared dual-gas type fireplace has a simple structure and low cost.

[utility model content]
The purpose of the utility model is to overcome the weak point of prior art, provides a kind of simple in structure, and cost is low, do not have to reveal, and sufficient combustion can use the two gas kind fireplaces of infrared type of two or more source of the gas.
The purpose of the utility model is achieved in that
The two gas kind fireplaces of a kind of infrared type; It is characterized in that the natural gas pressure maintaining valve that it comprises external natural gas; The liquefied gas pressure maintaining valve of external liquefied gas, the natural gas pressure maintaining valve is connected with main control valve through check valve respectively with the liquefied gas pressure maintaining valve, and the other end of main control valve is connected with natural gas nozzle and liquefied gas nozzle; The other end of natural gas nozzle and liquefied gas nozzle is connected with infrared burner, also is connected with flame-out safety guard on the main control valve.
The two gas kind fireplaces of aforesaid a kind of infrared type; It is characterized in that infrared burner comprises the infrared combustion chamber; In the infrared combustion chamber, be provided with induction tunnel; End at the air inlet of induction tunnel is provided with the nozzle installing rack, on the nozzle installing rack, is provided with two nozzles with induction tunnel disalignment angle.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that the center line of said nozzle and the center line of induction tunnel intersect in the air inlet center.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that the center line of said nozzle and the angle that the induction tunnel center line intersects are 9 °.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that said nozzle installing rack includes two installed surfaces with horizontal line inclination certain angle, and described two nozzles correspondingly are installed on the installed surface.
The two gas kind fireplaces of aforesaid a kind of infrared type; It is characterized in that check valve comprises valve body; In valve body, be provided with the passage that lets gas pass through, in passage, be provided with spool and valve plug, in passage, also be provided with and can valve plug withstood and makes valve plug seal the spring of spool pore.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that said spool includes air inlet and gas outlet, and said gas outlet is horn-like, and said valve plug passes through the spring roof pressure on the gas outlet.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that said spool is provided with external screw thread, in passage, are provided with internal thread, and spool is threaded with passage, between spool and passage, is provided with O type circle.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that flame-out safety guard includes natural gas flame-out protection device and liquefied gas flame-out protection device.
The two gas kind fireplaces of aforesaid a kind of infrared type is characterized in that also being connected with on the main control valve switching valve that burner and flame-out safety guard can be changed between natural gas and liquefied gas.
The utility model can use two or more source of the gas; Be connected with main control valve through check valve at the natural gas pressure maintaining valve of external natural gas and the liquefied gas pressure maintaining valve of external liquefied gas, realize the source of the gas directed flow, can not produce the gas leakage of flowing backwards; And employing infrared burner; The center line of the disalignment induction tunnel of two nozzles, making can both sufficient combustion from each nozzle, practices thrift source of the gas.And simple in structure, adult is low.
