产品特点 features 该系列球阀特别适用于各焦化厂焦炉、喷射循环系统高低压转换时使用。一、阀门的连接尺寸与原三通球阀相同,更换方便。 二、特制的增强聚四氟乙烯封圈,其耐磨强度大大提高,显著提高密封圈的使用寿命。三、独特的内部结构,不仅大大降低了生产成本,而且使加工与维修更加简单化。四、带倒密封结构的下装式阀杆,不仅防止了阀杆脱出,而且阀杆部位的密封更加可靠。 五、外型结构紧凑,独特三块式设计使阀门外观更完美。the valve series are especially applicable for thehigh/low-temperature conversion course in such fields as theaonia water in coke ovens or the injection circulating system incoke plants. 1.the connection dimension of the valve is identicalto that of the above-mentioned 3-way ball valve for convenientreplacement. 2.the specially-designed seal ring made from strongpolytetrafluoroethylene with much greater abrasion strength couldobviously enhance the service life of the ring. 3.the specialinterior structure applied not only reduces the production cost butalso simplifies the processing and maintenance work. 4.thelower-loading stem with backward sealing construction not onlyprevents the handle form backing-out but also ensures thereliability of the scaling part of the handle. 5.with compactstructure in configuration,the specially-designed 3-part featuremakes the valve much more perfect.
