The utility model can also with bivalve valve for pressure difference adapted, during use the pore on the combustion gas road blocked and gets final product, the utility model also can with self-priming magnetic valve adapted, during use the pore on the combustion gas road is blocked, cancel gusset piece simultaneously and get final product.
There is flange formed integrally therewith above-mentioned air intake duct end, and valve body is connected on the bearing by flange, and is communicated with intake elbow on the bearing.The intake elbow trachea.
There is flange formed integrally therewith end, above-mentioned combustion gas road, to connect single valve valve for pressure difference or bivalve valve for pressure difference or self-priming magnetic valve.Combustion gas has pore on the road, and tracheae is arranged in the pore, combustion gas is sent into the back cavity of single valve valve for pressure difference.
Be fixed with rubber seal in the above-mentioned obstruction, stop up the end and have the hole of matching with the push rod that links.Open water valve, block drives the interlock push rod and moves to left, and interlock push rod left end stretches into and stops up in the perforate of end institute, makes and stops up the compression spring that moves to left, thereby open passage (19).
The supporting base of oriented valve pocket (25) internal projection in the valve pocket of above-mentioned aqueous vapor interstage valve (25) is fixed with the splicing sleeve that supports the interlock push rod in the supporting base.
Have intermittent grooves on the above-mentioned valve rod, groove matches with screw on the valve rod base, has venthole on the valve rod, on the hole wall of giving vent to anger pore is arranged.Pore is two, one gross blow hole and a spilehole adjacent with gross blow hole, rotation valve rod can regulate gross blow hole and spilehole and give vent to anger hole wall and control valve on the registration of gas outlet, thereby open or close the combustion gas size that the combustion gas that enters main burner or adjusting enter main burner.
The utlity model has compact conformation, rationally distributed, easy to manufacture, be connected firmly, seal characteristics such as reliable.Be applicable to natural gas, liquefied gas, various combustion gas such as artificial coal gas are suitable for the water heater of various flows, can be respectively and single, double valve valve for pressure difference, self-priming magnetic valve adapted.
