排气阀是管道系统中必不可少的辅助元件，广泛应用于锅炉、空调、石油天然气、给排水管道中。往往安装在制高点或弯头等处，排除管道中多余气体、提高管道路使用效率及降低能耗。 　　ARSX/ARSH系列微量 排气阀ARSX/ARSH 系列在一般情况下，水中约含2VOL%的溶解空气，在输水过程中，这些空气由水中不断地释放出来，聚集在管线的高点处，形成空气袋（AIR POCKET）使输水变得困难，系统的输水能力可因此下降约5-15%。此微量排气阀主要功能就是排除这2VOL%的溶解空气，并适合装置于高层建筑、厂区内配管、小型泵站用以保护或改善系统的输水效率及节约能源。 　　单杆式（SIMPLELEVERTYPE）微量排气阀，为一类似椭圆形阀体，内部所有零件包括浮球、杠杆、杠架、阀座等均为304S.S不锈钢，内部使用标准排气孔径1/16"，适合用于{zg}达PN25工作压力环境。 主要规格： 　　公称通径：DN15-DN25 　　公称压力：PN10 PN16 PN25 　　CARX系列复合式排气阀 构造及用途： 　　本阀为圆桶状阀体，其内部主要含有乙组不锈钢球（STAINLESSSTEELBALL），杆（FLOATARM）及塞头（POPPET）。本阀装设于泵浦出水口处或送配水管线中，用以大量排除管中集结之空气，或于管线较高处集结之微量空气排放至大气中，以提高管线及抽水机使用效率，且于管内一旦有负压产生时，此阀迅速吸入外界空气，以保护管线因负压所生产之毁损。 操作原理： 　　当管内开始注水时，塞头停留在开启位置，进行大量排气，当空气排完时，阀内积水，浮球被浮起，传动塞头至关闭位置，停止大量排气，当管内水正常输送时，如有小量空气聚集在阀内到相当程度，阀内水位下降，浮球随之下降，此时空气由小孔排出，当抽水机停止，管内水流空时或遇管内产生负压时，此时塞头迅速开启，吸入空气，确保管线xx。 CARX系列整体单球式 　　复合式排气阀（清水用） 　　压力等级：PN10 　　公称通径：DN25-100mm(DN25为螺纹式，其余为法兰式) CARX系列分离式复合式排气阀（清水 污水共用） 　　压力等级：PN10公称通径：DN250-300mm CARX整体双球式复合式排气阀压力等级：PN10公称通径：DN250-300mm SCAR系列污水复合式排气阀 概述： 　　污水复合式排气阀原理与清水复合式排气阀相同，只是将结构略作改动，即将阀体加长，杠杆机构略作修改，使污物只积在阀体下部，不影响排气，不致漏水。 　　主要规格： 　　压力等级：PN10 　　公称通径：DN50-200mm

原文：
Exhaust valve is an essential auxiliary piping system components, widely used in boilers, air conditioning, oil and gas, water supply and drainage canal. Often installed in the high ground or elbow, etc., excluding extra gas pipeline, to improve management efficiency of road usage and reduce power consumption. ARSX / ARSH series of micro-exhaust valve ARSX / ARSH series in general, the water contains about 2VOL% of dissolved air in water during the air released from the water constantly, gathered at the high point of pipeline, and forms Air Bag (AIR POCKET) to make water more difficult, the system's water capacity could be reduced by about 5-15%, therefore. This trace function is to rule out the exhaust valve of this 2VOL% of dissolved air, and suitable for installation in high-rise buildings, factories in the region piping, small pumping stations to protect or improve water system efficiency and save energy. Single rod (SIMPLELEVERTYPE) trace exhaust valve, a similar oval body, internal parts, including all float, lever, bar shelf, stainless steel valve seats, etc. are 304S.S internal standard exhaust aperture 1 / 16 ", suitable for working pressures up to PN25 environment. Specifications: Nominal Diameter: DN15-DN25 Nominal pressure: PN10 PN16 PN25 CARX series hybrid exhaust valve Construction and Use: The valve for the cylinder-shaped body, its internal stainless steel ball containing mainly B (STAINLESSSTEELBALL), bar (FLOATARM) and Plug (POPPET). The valve installed at the pump outlet pipe in the water Transmission and Distribution Department or to exclude a large number of the air tube assembly, or gathering places higher in the micro-pipeline air emissions to the atmosphere, to improve the pipeline and pump efficiency, and Once a negative pressure in the pipe production, this valve quickly inhale outside air, to protect the pipeline because of the damage produced by negative pressure. Principle of Operation: When the pipe water injection, the plug head and stay in the open position, for a lot of exhaust, when the air drained, the valve inside the water, float is float, drive plug head to the closed position, to stop a lot of exhaust, water when the tube Normal delivery time, if a small amount of accumulation of air in the valve to a considerable extent, the water level dropped valve, float ball fall, then the air discharged from the hole, when the pumps stop, tube or the case of space-time water pipe negative pressure , the time Plug quickly open, inhaling the air, to ensure that pipeline full. CARX single ball the whole series Composite exhaust valve (water use) Pressure rating: PN10 Nominal Diameter: DN25-100mm (DN25 for the thread type, the other for the flange type) CARX series of separate composite exhaust valve (water for water sharing) Pressure rating: PN10 Nominal diameter: DN250-300mm CARX overall two-ball compound exhaust valve pressure rating: PN10 Nominal diameter: DN250-300mm SCAR Composite sewage discharge valve series Overview: Effluent composite theory and exhaust valve exhaust valve clean water the same compound, only minor changes to the structure, about body longer, leveraged institutions slightly modified, so that dirt plot only the lower part of the body, does not affect the exhaust, not leaking. Specifications: Pressure rating: PN10 Nominal Diameter: DN50-200mm
