A one-way gas-exhaust valve for use in passive disposal systems is described. The valve is explosion-proof and it does not offer any resistance at gas flow rates of up to 30 litres/minute. The design of the valve minimises the influence of wind velocities on pressure fluctuation in the disposal system.
描述了一种用于被动处理系统的单向排气阀。该阀具有防爆功能,在气体流速高达每分钟30升时不会产生任何阻力。该阀的设计将风速对处理系统压力波动的影响降至最低。
