PFA襯里不銹鋼取樣閥采用密封連接形式設置于四氟手套箱上方，四氟手套箱體在操作方位設有可快速開關閉視窗門，后方設有氮氣進出口，連接氮氣氣源后進行箱體內部及取樣瓶內空間清掃，安裝瓶體穩妥后小心按壓頂部操作手柄，使物料溫和而有控制地流入取樣瓶內。當獲得足夠的樣品時，松開頂部按壓操作手柄，以確定安全停止了取樣過程。通過耐酸堿橡膠手套將取樣瓶從閥體上安全取下，并裝好取樣瓶蓋，可進行再次氮氣空間清掃，以進—步保護操作人員，最終從四氟手套箱內取出取樣瓶完成工藝取樣工作。

     The PFA lined stainless steel sampling valve is installed above the Teflon glove box by a sealed connection. The Teflon glove box is equipped with a window door that can be quickly opened and closed in the operation direction, and a nitrogen inlet and outlet is set in the rear. After connecting the nitrogen gas source, the inside of the box and the space in the sampling bottle are cleaned. After the bottle body is installed stably, carefully press the top operation handle to make the medium flow into the sampling bottle gently and controlled. When sufficient medium is obtained, release the top press operating handle to make sure that the sampling process is stopped safely. The sampling bottle can be safely removed from the valve body by wearing acid and alkali resistant rubber gloves, and the sampling bottle cap can be installed. The space can be cleaned again by nitrogen to further protect the operators. Finally, the sampling bottle can be taken out from the Teflon glove box to complete the process sampling.
