 QB1-10 single-port exhaust valve Overview: QB1 mainly by the single-port exhaust valve body, valve cover, valve stem, float, exhaust nozzles and other components. For small diameter pipes (tubes for the φ50-200), its role as the exhaust pipe, the pipe will not breath, air resistance, such as the pump power at any time when the pipe negative pressure, automatic suction to protect pipeline safety . Action principle: When the gas discharge pipe, the pipe of the air in the water under pressure into the body cavity, and discharged from the exhaust nozzle, along with the water pipe filled body cavity, so that the buoyancy of float in the water under the action of moving up the exhaust nozzle clogging, to achieve self-sealing, pipe in the normal line, the water under the action of air pressure constantly into the body cavity of the upper part of the exhaust valve, forcing the float down, leaving the original sealing position, mouth and from the exhaust air discharge point, followed by the float has returned to its original position from the seal, therefore, the exhaust valve during normal operation of the valve is always open, float repeated the action, air is discharged . When you need to repair or clean the body cavity, the valve should be closed. Single-port exhaust valve and the main use of performance specifications: 1, the valve for temperature does not exceed 100 ℃ water, hot water pipe to discharge all the air inside the tubes. 2, install dual-port exhaust valve, under the protection must be installed in a valve, ball valve (Q41F-16), so as not to test without water. 3, the demand side for side exhaust valve flange sizes, such as changes in the flange size indicated on the contract.
