產品結構特點 Construction features 1）、本系列閥門主體采用鑄鍛結構，具有平行雙密封副半強制雙向密封，密封面到位運動和楔緊運動分步作用，實現零泄露。 2）、密封面之間摩擦系數小，起閉方便，而且，密封面的磨損有自動補償功能。 3）、結構簡單，緊湊，檢修方便，使用壽命長。 4）、閥蓋填料室設有真空密封機構，具有自脹壓緊作用，并且，各連接面采用高強膨脹材料密封，使系統與大氣隔離，具有良好的真空密封性能。 5）、本系列閥門連接形式可為法蘭連接及焊接連接兩種，驅動方式為手動、電動兩種。尤其適用于火電廠汽機冷凝和真空負壓系統，起到真空密封隔離作用。 1) the main body of this series of valves adopts the cast forging structure, which has the double seal of the parallel double seal, the sealing of the sealing surface of the valve is in place, and the movement of the sealing cover in place and the step of the wedging movement are used to realize zero leakage. 2) the friction coefficient between the sealing surface is small, and it is convenient to operate. Moreover, the wear of the sealing surface has automatic compensation function. 3) simple structure, compact, convenient maintenance, long service life. 4), the cover packing room equipped with vacuum sealing mechanism, have since the expansion pressure effect, and the junction surface using high-strength packing material, make the system from the atmosphere, has a good vacuum seal performance. 5) the valve connection form of this series can be two kinds of flange connection and welding connection, and the driving mode is manual and electric. Especially suitable for the condensing and vacuum negative pressure system of the power plant. 適用介質：水、氣、油品、天然氣和酸堿腐蝕性介質 適用溫度：-196~425℃ 驅動方式：手動、氣動、電動等 公稱壓力：1.0~10.0MPa 公稱通徑：DN50~500mm Applicable media: water, gas, oil, gas and acid and alkali corrosive medium Applicable temperature: -196~425℃ Driver: manual, pneumatic, electric, etc Nominal pressure: 1.0 ~ 10.0MPa Nominal size: DN50~500mm 試驗壓力 Test prssure 截止閥結構長度和外接尺寸 Main connection dimensions
