Overview of double port exhaust valves
QB2-10 dual exhaust valve by the valve body, valve cover, valve stem, floating ball, exhaust nozzle and other components. Two port exhaust valve applies to the temperature of not more than 100 degrees of water, hot water pipe, so that all the air pipe exhaust. Two port exhaust valve for water, hot water, * * * high temperature 100 degrees on the pipeline, so that all the pipe gas discharged
 
Function and performance of double port exhaust valve
When you need to discharge the air in the pipeline, should reverse rotating stem clockwise, the valve rod and the valve rises, make the air inside the pipe under the action of the water pressure into the body cavity, and is discharged from the exhaust pipe of the water in the mouth, with the full body cavity, to float in the water buoyancy, to moving the exhaust nozzle clogging, achieve self sealing, the pipeline in the normal line, the water in the air pressure under the action of the upper body cavity continuously discharged into the exhaust valve, forcing the float down, leaving the original sealing position, then the air is discharged from the exhaust mouth, with the floating ball, and back to the original position of self sealing therefore, the valve exhaust valve in the normal work is always open, the floating ball continue to repeat the action of air discharged continuously, when the need for maintenance or cleaning the body, due to the closure of the valve. Double port exhaust valve, clockwise rotation of the stem is closed.
 
Two port exhaust valve considerations
1, D > 350mm line select single port exhaust valve (QB1-10).
2, the installation of double port exhaust valve, must be installed below a protective valve, ball valve (Q41F-16), so as not to test the water supply.
3, such as the buyer side of the exhaust valve flange size changes in size, please specify in the contract flange connection size.
