閥門的啟閉過程∶開啟閥門時，要先旋轉手輪，使塞子上升，與密封面脫離，再旋轉手柄90°，使塞子的通道和閥體的通道相通，連到開啟的。而開閉的過程是先旋轉手柄90°，使塞子的通道和閥體的通道垂直，再旋轉手輪，使塞子下降，連接密封 RETZ Process of opening and closing of thevalve. when opening the valve, first ofall, turn the hand wheel tomake the plug lifted and separated with the sealed surface,then turn the handle by 90 degree to connect the channel of plugto the channel of valve body, so that the valve is opened; when closing the valve, first of all, turn the handle by 90degree to make the channel of plug veertical to the channel of valve body, and then turn the hand wheel to descend the plug, so that the valve is closed.

性能特點 Performance characteristics

轉動90度就能開關，啟閉迅速，操作方便 It can be opened and closed by turning 90 degrees, which is fast and easy to operate

閥門沒有空腔給介質積聚 The valve has no cavity to accumulate medium

雙向流動，開關動作輕 Two way flow, light switching action

閥體和密封面間設有油槽，可隨時通過油嘴向閥座注入密封油脂，增加密封性能retz品牌 There is an oil groove between the valve body and the sealing surface, which can inject sealing grease into the valve seat at any time through the nozzle to increase the sealing performance

啟閉過程是在密封面脫離的狀態下進行的，不會造成密封面的磨損 The opening and closing process is carried out when the sealing surface is detached, which will not cause wear on the sealing surface
