四氟密封刀闸阀
PTFE knife gate valve
由于四氟密封圈相对橡胶来讲比较硬为进一步提高密封效果,本刀闸阀在四氟密封圈背向闸板的一侧与所述阀座的结合部之间放置 O型密封圈,通过O型密封圈的弹性力使四氟密封圈与闸板紧密结合达到密封要求,本产品可以使得四氟密封圈在使用过程中不会造成密封刮伤、脱落现象,而且是四氟密封圈更换、安装十分方便,即卸掉阀座更换相应的四氟密封圈就可以重新使用,大大提高了刀闸阀的使用效率和使用成本。号:(200720108248.5)
In order to improve the effect of sealing,for the PTFE is better than rubber in stiffer. An O-ring is seated at the join of the PTFE and the body to make PTFE and disc tightly to meet the sealing requirement. This patent products can use PTFE to protect being scraped and desquamated when using ,and is convenient for PTFE to replaced and installed .That means relied the valve seat to replace the PTFE ,which improve the efficiency and cost of the knife gate valve a lot .
