产品特点 Features

该系列球阀特别适用于各焦化厂焦炉氨水、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 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.
