Val-Matic Air 阀s to the Rescue

Val-Matic Air 阀s to the Rescue

The water supply distribution system consists of pipelines that help get water and wastewater from point A to B. Purging air from the pipeline is necessary because trapped air significantly reduces pump and/or pipeline efficiency and life. This can cause surges/water hammer and accelerated corrosion. Air is sometimes removed from the line with a manual vent or fire hydrant during initial start-up, but this method does not provide continual air release during system operation, nor does it provide vacuum protection. 今天, municipalities use a variety of automatic air valves at the pump discharge and along the pipeline.

Air valves are hydromechanical devices designed to automatically release air and wastewater gases or admit air during the filling, 排水, or operation of liquid piping systems for water and wastewater services. This part can be installed in numerous applications from local peaks in a system and changes of the pipe diameter to street underpasses and by filter installations. Advantages of an air valve includes the following:

• 减少腐蚀
• Decreased energy consumption and operation costs
• Increased accuracy in flow metering
• Reduces the delay time for filling of mains, which increases the efficiency of the pump and pipeline
• Decreases the risk of water hammering
• Sudden movement of air pockets can result in a rapid change in the flow velocity, leading to high pressure surges of a destructive nature. By decreasing air pockets in the pipeline, this also reduces the chance of a surge.

There are three basic types of air valves standardized in the American 自来水厂 Association (AWWA) Standard C512-15:

• 空气释放
  • Releases relatively small quantities of air from a pressurized line as needed
  • Also known as a small orifice air valve and as a pressure air valve
• 空气/真空
  • Discharges large quantities of air from non-pressurized pipes and are used mainly when filling a line
  • Also makes it possible to admit large quantities of air when lines are drained and when the pressure drops suddenly
  • 又称动能阀, 大孔口空气阀, 真空断路阀, 低压气阀, 和空气安全阀
• 组合气阀
  • Fulfills the tasks required of both types of valves – air release and air/vacuum
  • Discharges or intakes large volumes of air when filling or emptying a system and releases small volumes of air when the line is pressurized as needed
  • Also known as double orifice air valves, double acting, or dual orifice

The 阀式空气释放阀 and Combination Air valve are manufactured in accordance with rigorous industry requirements given in the AWWA Standard C512. Each valve features a 316 stainless-steel trim, 全尺寸端口, ANSI threaded or flanged connections, 严格的测试. From the float material to the shape of the body, Val-Matic Air 阀s are designed for optimum performance. 两个阀门都是 NSF 61和372认证 for use in drinking water applications.
