Abstract

The invention relates to a dual-fuel oven valve without replacing nozzles. The dual-fuel oven valve without replacing a nozzle comprises a valve body, a valve core, a valve rod, a pressing plate, a pressure spring and a valve cover, wherein the valve body comprises a gas guide cavity, a conversion valve making a valve core cavity communicate with the gas guide cavity, and a gas vent cavity; the nozzles comprise the natural gas nozzle and the liquefied gas nozzle, the liquefied gas nozzle is arranged at the suspension end of the valve core cavity, the natural gas nozzle is arranged at the gas vent end of the gas vent cavity, and the axes of the liquefied gas nozzle and the natural gas nozzle coincide; a gas guide hole corresponds to the conversion valve; when the conversion valve is closed,the liquefied gas flows out through the liquefied gas nozzle, the gas vent cavity and the natural gas nozzle; and when the conversion valve is opened, the natural gas flows into the gas vent cavity through a core part, the gas guide hole, the conversion valve and the gas guide cavity, the natural gas flows into the gas vent cavity through the core part and the liquefied gas nozzle, and the natural gas is supplied to the gas oven through the natural gas nozzle. According to the arrangement of the gas guide cavity, the gas vent cavity and the conversion valve, the natural gas nozzle and the liquefied gas nozzle are connected in series; and when conversion is needed, the conversion valve is operated by a screwdriver, so that the use is convenient.

Description

technical field [0001] The invention relates to a gas valve for a gas oven. Background technique [0002] In the current prior art, an oven valve includes a valve body, a valve core, a valve stem, a pressure plate, a pressure spring and a valve cover. The valve body includes a valve core cavity and an air inlet port communicating with the valve core cavity. There is a nozzle at the end, and a stem channel is set on the bonnet; the stem includes a stem part, a baffle plate and a waist-shaped drive plate; a waist-shaped hole is set on the pressure plate; the valve core includes a drive cylinder with a radial insertion groove The core part and the hollow core part with one end open, the core part is provided with an air inlet hole, and the end opening is an air outlet, the valve stem part passes through the valve stem channel and extends to the valve cover, and the driving plate part passes through the waist shape on the pressure plate. Holes and pressure springs, the driving ...
