Abstract
The utility model discloses a mechanical fixed-proportion gas/air mixing device which consists of a backpressure type pressure adjuster, an adjustable fan, a gas/air coaxial pipe, an air pipe, a gas pipe, a swirl vane and a nozzle, wherein the air pipe is vertically and fixedly connected with the side part of the gas/air coaxial pipe; the air inlet end of the air pipe is connected with the adjustable fan through an air pipeline; the gas pipe extends into the coaxial pipe from the bottom of the gas/air coaxial pipe, and is fixedly connected with the coaxial pipe; the backpressure type pressure adjuster is connected with the bottom of the gas pipe and then connected with the air pipeline through an air pressure guide pipe; the swirl vane is arranged at the outlet of the gas pipe; and a gas nozzle is arranged at the tail end of the gas pipe in a direction vertical to the gas outlet of the vane. Connection is realized by using air pressure on the air pipeline, the air pressure guide pipe and the backpressure type pressure adjuster on the gas pipeline, so that pressure balance between gas and air is realized; furthermore, the gas and the air are mixed automatically according to a fixed proportion by combining the air throttling swirl vane and the gas nozzle, so that the mixing reliability and the mixing precision are improved; and the mechanical fixed-proportion gas/air mixing device is not influenced by outside condition changes, such as heat load, water, electricity and the like.
Description
Technical field:
The utility model belongs to a kind of fuel gas buring utensil and uses equipment, particularly a kind of mechanical gas/air certainty ratio gas mixing device.
Background technology:
At present, fuel gas buring utensil electricity consumption minor gas mixing device is prone to the influence of change of external conditions such as affected by hot loading, water, electricity, thereby has reduced reliability and mixed gas precision.
Summary of the invention:
The purpose of the utility model is to provide a kind of mechanical gas/air certainty ratio gas mixing device, and this apparatus structure is simple, easy to use, the not influence of change of external conditions such as affected by hot loading, water, electricity, thus improved the reliability and the precision of mixed gas.
As above design; The technical scheme of the utility model is: a kind of mechanical gas/air certainty ratio gas mixing device is characterized in that: be made up of back pressure type pressure regulator, adjustable blower fan, combustion gas/air coaxitron, air hose, Gas Pipe, swirl vane and shower nozzle; Air hose is vertical affixed with combustion gas/air coaxitron sidepiece; The inlet end of air hose is connected with adjustable blower fan through air duct; Gas Pipe stretches to coaxitron and affixed with it from the bottom of combustion gas/air coaxitron; The back pressure type pressure regulator is connected with the Gas Pipe bottom, and is connected with air duct through the air connecting pipe; The Gas Pipe exit is provided with swirl vane, establishes gas spray head with the Gas Pipe terminal of leaf gas outlet vertical direction.
Above-mentioned swirl vane is made up of sleeve pipe and 12 blades being fixed on the sleeve pipe, and every blade and 45 ° of sleeve pipes are tangent.
Back-up ring is equipped with on above-mentioned Gas Pipe top.
Above-mentioned swirl vane adopts the plug-in type air with throttling/rotating vane.
