進口直流式截止閥，直溜式,Y型截至閥性能描述 Performance description

(直溜式,Y型)直流式截止閥的波紋管加填料雙重密封設計，具有雙重保險，使得閥桿處密封更嚴密 RETZ The corrugated pipe and packing double sealing design of (straight type, Y-type) DC stop valve has double safety, which makes the valve stem more tightly sealed

采用錐面密封，密封面不殘留雜質，在趨于關閉時，密封面具有自清潔作用 Conical sealing is adopted, and there is no residual impurities on the sealing surface. When it is closed, the sealing surface has self-cleaning effect

錐形密封面，可以使閥桿軸向力轉化為密封力時具有放大作用,密封性能更好 Conical sealing surface can enlarge the axial force of valve rod when it is converted into sealing force, and the sealing performance is better

波紋管的結構 Structure of bellows

閥芯結構 Valve core structure

錐面密封∶密封面不殘留雜質∶在趨于關閉時，密封面具有自清潔作用，實現線性密封 Conical sealing: no impurities remain on the sealing surface: when the sealing surface tends to close, the sealing surface has self-cleaning effect to achieve linear sealing

平衡雙閥瓣密封∶小閥瓣緩解壓力后帶動大閥瓣輕松打開retz品牌 Balanced double disc sealing: small disc releases pressure and drives large disc to open easily

平面軟密封∶開啟和關閉時軟密封表面可防止火花產生，適用于氣體介質或耐腐蝕要求的工況 Flat soft seal: the soft seal surface can prevent sparks when opening and closing, and is suitable for working conditions with gas medium or corrosion resistance requirements
