四氟密封刀閘閥
PTFE knife gate valve
由于四氟密封圈相對橡膠來講比較硬為進一步提高密封效果,本刀閘閥在四氟密封圈背向閘板的一側與所述閥座的結合部之間放置 O型密封圈,通過O型密封圈的彈性力使四氟密封圈與閘板緊密結合達到密封要求,本產(chǎn)品可以使得四氟密封圈在使用過程中不會造成密封刮傷、脫落現(xiàn)象,而且是四氟密封圈更換、安裝十分方便,即卸掉閥座更換相應的四氟密封圈就可以重新使用,大大提高了刀閘閥的使用效率和使用成本。號:(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 .
