QB1-10 threaded single port exhaust valve

QB1-10 internal threadsingleExhaust valvesummary:
QB1 single portexhaust valveMainly composed of valve body, valve, upper cover, valve stem, floating ball, exhaust nozzle, etc. The pipe used for small-diameter pipelines is a diameter of 50-200. It serves as an exhaust function for the pipeline, preventing air blockage or blockage. In the event of a power outage in the water pump, negative pressure may occur inside the pipe at any time. Automatic suction can protect the safety of the pipeline.
QB1-10 Internal Thread Single Portexhaust valveWorking principle:
When it is necessary to discharge gas from the pipeline, the air inside the pipeline enters the body cavity under the pressure of water and is discharged from the exhaust nozzle. As a result, the water in the pipeline fills the body cavity, causing the floating ball to move upward under the buoyancy of water, blocking the exhaust nozzle and achieving self sealing. During normal operation of the pipeline, the air in the water is continuously discharged into the upper part of the body cavity of the exhaust valve under the pressure, forcing the floating ball to descend and leave its original sealed position. At this time, the air is discharged from the exhaust nozzle, and the floating ball returns to its original position for self sealing. Therefore, the valve of the exhaust valve is always open during normal operation, and the floating ball continues to repeat the above action while the air is continuously discharged. When it is necessary to inspect or clean the body cavity, the valve should be closed.
QB1-10 internal threadsingleExhaust valvePurpose and main performance specifications:
1. This valve is suitable for discharging all air inside water and hot water pipelines with a temperature not exceeding 100 ℃.
2. Install a dual port exhaust valve, and be sure to install a protective valve and ball valve (Q41F-16) underneath to prevent water interruption during inspection.
3. If the buyer requests any changes in the size of the exhaust valve flange, please indicate the flange connection size in the contract
