 I. Overview 

 (ARVX) micro exhaust valve for the highest point of the piping elbow or breath or a place, to exclude the gas pipe to clear the pipeline, to work properly. If you do not install the valve, pipe air resistance at any time, so that the pipeline appears not meet the design requirements of water capacity, followed by; pipeline power when in operation, stop the negative pressure pump pipe in a timely manner will cause vibration or pipeline rupture. Row, into the air intake valve on the tube quickly, to prevent vibration or pipeline rupture. Of principle: When water enters the pipe, the plug to stop the tip positioning the lower part of the large number of exhaust, the air drained, the water floated the ball into the valve, the drive plugs into the close, to stop the exhaust. In the normal operation of the pipeline would naturally produce a small amount of gas, these gases will be gathered in the upper part of the tube, to a considerable extent, the water level dropped valve, float downstream decline in the gas discharged from the hole, where there is power failure, stop the pump, when the air flow inside the tubes appeared negative, float downstream decline in a large number of open holes for the intake to ensure pipeline safety. Medium temperature :0-80 ℃ main parts as follows:
