The opening and closing component of Z41H cast steel flange gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. When the gate valve is closed, the sealing surface can be sealed solely by the pressure of the medium, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the pressure of the medium to ensure the sealing of the sealing surface.
Z41H鑄鋼法蘭閘閥的啟閉件是閘板,閘板的運動方向與流體方向相垂直,閘閥只能作全開和全關(guān),不能做調(diào)節(jié)和節(jié)流。閘閥關(guān)閉時,密封面可以只依靠介質(zhì)壓力來密封,即只依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封。
Z41H cast steel gate valve is suitable for cutting off or connecting pipeline media in various systems of petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN1.6~16.0MPa and working temperature ≤ -29 ℃~550 ℃. Manual flange gate valves are suitable for media such as water, oil, steam, acid, alkali, ammonia, urea, and sulfur-containing natural gas. The operation modes include manual, gear transmission, electric, pneumatic, etc.
