| 1、用途Use |
適用于區域供熱（熱電聯產）、輸熱、輸油及除氧水等工業管錢。
Suitable for the pipeline to transfer cogeneration,cogeneration,heating,oil,deoxygenized water and etc. |
| 2、結構特性Structure Features |
閥門是由全焊接的閥體和增強四氟密封墊組成，閥門可在有雜質化學物質的情況下進行頻繁操作，運行可靠。采用浮動球結構，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.Evon when the pressure is not stable,the valve can also have a good sealing. The stem can be extended which is good for keeping the tempeture stable. |
