節能焦爐專用三通球閥 Q44M、Q45M 產品特點 Features 該系列球閥特別適用于各焦化廠焦爐氨水、噴射循環系統高低壓轉換時使用。 一、閥門的連接尺寸與原三通球閥相同，更換方便。 二、特制的增強聚四氟乙烯封圈，其耐磨強度大大提高，顯著提高密封圈的使用壽命。 三、獨特的內部結構，不僅大大降低了生產成本，而且使加工與維修更加簡單化。 四、帶倒密封結構的下裝式閥桿，不僅防止了閥桿脫出，而且閥桿部位的密封更加。 五、外型結構緊湊，獨特三塊式設計使閥門外觀更完美。 The valve series are especially applicable for the high/low-temperature conversion course in such fields as the ammonia water in coke ovens or the injection circulating system in coke plants. 1.The connection dimension of the valve is identical to that of the above-mentioned 3-way ball valve for convenient replacement. 2.The specially-designed seal ring made from strong polytetrafluoroethylene with much greater abrasion strength could obviously enhance the service life of the ring. 3.The special interior structure applied not only reduces the production cost but also simplifies the processing and maintenance work. 4.The lower-loading Stem with backward sealing construction not only prevents the handle form backing-out but also ensures the reliability of the scaling part of the handle. 5.With compact structure in configuration,the specially-designed 3-part feature makes the valve much more perfect. 產品型號 Product type 零件名稱 Accessory name 零件材料 Accessory material Q44M-40DN25 Q41F-40DN25 閥體、閥蓋 body,Bonnet WCB 球體 Ball 1Cr18Ni9Ti 閥桿 Stem 2Cr13 密封圈 Sealing ring 增強聚四氟乙烯 RPTFE 填料 Stuffing V型聚四氟乙烯 V-shaped PTFE 主要連接尺寸 公稱壓力 PN(MPa) Nominal pressure 試驗壓力(Mpa) 殼體 Shell 高壓液密封閉 High-pressure liquid sealing 低壓氣密封 Low-pressure hermetic sealing 4.0 6.0 4.4 0.6 適用溫度 Applicable temperture ≤150℃ 氨水等 Liquid ammonia, etc
