Abstract

The present invention relates to a double gas source conversion valve for gas warmer. It includes the following several portions: valve core with knob, main valve body, nozzle assemblage and once gas inlet regulation cover. The main body of valve core can be turnably insert-mounted in the main valve body, its one end is passed through said main valve body and is equipped with a shifting fork, the nozzle assemblage is mounted on side surface of said main valve body, the high combustion valve gas nozzle and low combustion value gas nozzle are mounted in the gas outlet on the nozzle assemblage, the gas feeding end of said once gas inlet regulation cover is cover-mounted on the gas outlet, its another end is inserted into main combustor, on the described once gas inlet regulation cover a shifting bar is fixedly mounted, one end of said shifting bar is inserted into the shifting fork. Said invention can convertibly use two kinds of gas.

Description

technical field [0001] The invention relates to a gas heater component, in particular to a dual gas source gas heating component, in particular to a dual gas source switching valve for a gas heater. Background technique [0002] At present, with the continuous improvement of transportation technology and the increasing shortage of oil resources, natural gas, biogas and other low calorific value gases have gradually entered people's daily life, and the single energy source in cities is being gradually broken by the multi-energy supply system. At the same time, it has become possible to connect the gas supply pipelines of coal gas, natural gas, liquefied petroleum gas, biogas and other energy sources. People can choose the appropriate gas to use according to market price changes and gas supply conditions. Taking the gas heater as an example, in the past, it was a single structure dedicated to liquefied petroleum gas or natural gas. Due to the different calorific values ​​of va...
