進口角式截止閥性能描述 Performance description

角式截止閥的波紋管加填料雙重密封設計，具使得閥桿處的密封更有雙重保險，安全可靠，密封面不殘閥門采用錐面密封，留雜質，在趨于關閉時，密封面具有自清潔作用。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，密封性能更佳 RETZ The double sealing design of the corrugated pipe and packing of the angle stop valve makes the sealing at the valve stem more double safe, safe and reliable. The sealing surface does not leave any residue. The valve is sealed with a conical surface, leaving impurities. When it tends to close, the sealing surface has a self-cleaning effect. Conical sealing surface can enlarge the axial force of valve stem when it is converted into sealing force, and the sealing performance is better.

波紋管的結構 

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 

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 retz品牌 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
