焦?fàn)t專用球閥 Q41M
產(chǎn)品特點(diǎn) Features
該系列球閥特別適用于各焦化廠焦?fàn)t氨水、噴射循環(huán)系統(tǒng)高低壓轉(zhuǎn)換時(shí)使用。
一、閥門的連接尺寸與原三通球閥、直通浮動(dòng)球閥相同，更換方便。
二、特制的增強(qiáng)聚四氟乙烯封圈，其耐磨強(qiáng)度大大提高，顯著提高密封圈的使用壽命。
三、獨(dú)特的內(nèi)部結(jié)構(gòu)，不僅大大降低了生產(chǎn)成本，而且使加工與維修更加簡單化。
四、帶倒密封結(jié)構(gòu)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(jié)構(gòu)緊湊，獨(dú)特三塊式設(shè)計(jì)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.
