用途 Use
適用于區(qū)域供熱(熱電聯(lián)產(chǎn))、輸熱、輸油及除氧水等工業(yè)管線。
Suitable for the pipeline to transfer cogeneration, heating, oil, de oxygenized water and etc.
結(jié)構(gòu)特性 Structure Features
閥門是由全焊接的閥體和增強(qiáng)四氟密封墊組成,閥門可在有雜質(zhì)及化學(xué)物質(zhì)的情況下進(jìn)行頻繁操作,運(yùn)行可靠。
采用浮動(dòng)球結(jié)構(gòu),斜面彈性墊圈保證密封圈緊壓在球體之上,即使在壓力不穩(wěn)定的情況下,閥門也可以保證良好的密封性。
閥桿可加長,易用于保溫。
The valve is composed by a full welding body together with the RPTFE sealing which ensures the valve can work well in case of there are imoutries or chemical substance.
Floating ball structure and the flexible seat will ensure the ball and the sealing connects each other tightly. Even when the pressureis not stable, the valve can also have a good sealing.
The stem can be extended which is good for keeping the temperature stable.
