a, what is a stainless steel flue check pneumatic valve
stainless steel flue check pneumatic valve belongs to flue check pneumatic valve is a kind of classification, general use on the discharge of oil gas pipeline of the kitchen. Connected with the exhaust pipe of lampblack machine, stainless steel flue check the body of the pneumatic valve is usually made of stainless steel plate stamping manufacture, the outer layer of the lacquer that bake, prevent hair body rust, not only effectively prevent the flue gas injection, and has the fire prevention function.
2, stainless steel flue check working principle of the pneumatic valve
flue check pneumatic valve refers to rely on automatically by the lampblack machine thermal flow and open, her breath valve plates, used to prevent lampblack flow back of pneumatic valve, also known as flue check pneumatic valve, smoke, flue isolator. Flue check pneumatic valve belongs to a kind of automatic pneumatic valve, its main role is to prevent lampblack flow back, only allowed to flow in one direction airflow direction and stop the flow. When the temperature of the flue reaches ° ( Flue temperature reached ° default for flue with open flames, pneumatic valve body on the back of the temperature control element, touches off the switch. Pneumatic valve plates under the action of spring rebound force close the pneumatic valves, stop the fire spread through the smoke vent to indoor. This kind of pneumatic valve is to rely on the force created by the flow of the medium itself in the line of the automatic opening and closing, belongs to a kind of automatic pneumatic valves. Check pneumatic valve used in pipeline system, its main function is to prevent the backflow medium, the pipeline can be applied to a variety of media. Check pneumatic valve installed in the pipeline, that is, to become a full line of fluid components, one of the flue check pneumatic valve, also known as interior wall cap, also is the ministry of construction to promote environmental protection product. In the modern housing construction, has been widely applied. It can prevent lampblack flow back, and pipeline connection.
3, how to choose and buy stainless steel flue check pneumatic valve
the non-return market now there are many different kinds of pneumatic valve, can be roughly divided into a built-in check pneumatic valve and two external non-return pneumatic valve: built-in pneumatic valve is located in the flue wall, the installation process is more convenient, split aperture size without any requirements, as repairing measures, have lampblack changing family decorates to have good home can only temporarily solve the problem. Because of the built-in non-return pneumatic valve with lampblack machine pipe outlet out the wind, will produce noise; Also blocking the soot discharge resistance, long time will produce large amounts of oil dirties, and oil will follow the metope ceramic tile into the kitchen, so neither beautiful nor difficult to clean up, increased the housewife's troubles. External flue non-return pneumatic valve, small beautiful, convenient installation. Outlet and outlet out the wind, the lampblack machine does not produce noise. And around the perimeter of the pneumatic valve is equipped with the sealing ring, can prevent oil adhesion, avoids the one-way pneumatic valve can not open or close the lax. In addition, pneumatic valve plates below the guiding device, also has oil dirties will flue by guiding device suitable nozzle flow into the public, will not go back to room. Can effectively eliminate the dirt, prevent harmful flue gas entering, can thoroughly solve the problem of changing, smoke, backward and peculiar smell, improve air quality in kitchen, toilet, maintain indoor air fresh, achieve real comfortable and healthy home environment.
