As regulators increasingly home in on everyday sources of pollution, tighter restrictions on the emission of smog-forming volatile organic chemicals Globe Valves can be expected on household products like hair spray. Many of these liquids can be delivered by means of hand-operated pumps, like the familiar glass cleaner variety. But daily users -- hair stylists, for instance -- are likely to grow weary of the constant pumping. So a Swedish company, Inter Airspray A.B., has developed Eurospray, an alternate to conventional aerosols and pumps. It is a refillable bottle pressurized with ordinary air. A pump is in the base of the bottle. A user removes the screw-off top, pours in the desired liquid, replaces the top and, grasping the top in one hand and the bottom in the other, Reducing Valves pumps in a push-pull stroke. According to the company, 15 to 20 strokes will build enough pressure to propel half the contents of an 11-ounce bottle and pressure will hold for three to six months on the shelf. A relief valve pops open if inside pressure reaches 70 pounds per square inch. On the negative side, the containers would not work well with all liquids, particularly those that might be oxidized by the oxygen in air, and they are expensive.Forged Steel Valves The bottles are available from L.D. Systems of Charlotte, N.C., for $7.50 each plus $3.50 for shipping and handling. Diagram shows operation of a smog-free pump for liquids. (Sourc: L.D. Systems)

作为监管者越来越多家庭在日常污染源，对烟雾排放更严格的限制，形成有机挥发物可以预期的发胶等家用产品。这些液体有许多可以交付手段的手操作泵，如熟悉各种清洁玻璃。但是现在，每天用户 - 发型师，比如 - 有增长厌倦不断抽水。因此，一家瑞典公司，国际米兰Airspray抗体，已开发Eurospray，替代传统的气溶胶和泵。这是一个普通的不能再充气的空气瓶压力。甲泵是在瓶子的基础。用户删除螺丝起飞前，在所需的液体浇注，取代了顶部，一只手抓住顶部和在另一方面，在一推水泵底拉中风。据该公司称，15至20杆将建立足够的压力推动一半的内容长达11盎司一瓶和压力将举行3至6个月，在货架上。安全阀就会被打开，如果内部压力达到每平方英寸70磅。在消极方面，容器就难以发挥作用的所有液体，特别是那些可能会被空气中的氧气氧化，而且价格昂贵。瓶子可以从L.D.系统为每个7.50美元外加3.50美元的夏洛特，运输和处理。图显示了操作的烟雾，液体无泵。（Sourc：斯塔弗尔系统）
