Gate valve

The umbrella gear worm gear manual stainless steel 304 penetrating knife gate valve is a valve controlled by the umbrella gear worm gear box as the secondary worm gear transmission. The valve is opened and closed by rotating the matching handwheel. The valve body is made of stainless steel 304 material. The valve body of the penetrating knife gate valve has no seat groove, which can effectively prevent medium blockage. During the closing and opening process, the valve seat and gate always move closely, making the valve opening and closing force stable and having the characteristics of cutting off the medium.

The stainless steel 304 umbrella gear worm gear manual penetrating knife gate valve is a high-performance valve designed specifically for harsh industrial environments. It is made of high-quality stainless steel 304 material and has excellent corrosion resistance, wear resistance, and compressive strength. It is suitable for cutting control of slurry, granular media, or corrosive fluids in water treatment, mining, chemical, paper making, and other fields. Its unique penetrating blade gate design, combined with the dual drive mode of bevel gear and worm gear, can achieve fast opening and closing and precise flow regulation, meeting the efficient operation requirements under complex working conditions.

核心结构与技术优势
1. 材质与工艺 
   - 阀体与闸板：选用ASTM 304不锈钢精密铸造，表面经抛光或喷砂处理，耐酸碱腐蚀、抗高温氧化（适用温度-29℃~200℃），硬度高、寿命长。  
   - 密封组件：闸板与阀座采用硬密封+弹性填料双重密封结构，确保零泄漏；EPDM/FKM/VITON等材质密封圈可选，适配不同介质需求。  

2. 穿透式刀闸设计 
   - 刀形闸板：超薄楔形刀刃结构，可轻松切断纤维、颗粒、泥浆等粘稠介质，避免卡阻与堆积，尤其适合含固体悬浮物的管道系统。  
   - 直通流道：全通径设计，流阻近乎为零，减少介质冲刷磨损，保障长期稳定运行。  

3. 驱动方式灵活适配
   - 伞齿轮驱动：适用于高扭矩、大口径阀门（DN300以上），通过90°转向齿轮箱放大操作力，单人即可轻松启闭，节省人力成本。  
   - 蜗轮蜗杆驱动：具备自锁功能，可精确控制闸板行程，防止介质冲击导致闸板位移，适合需要频繁调节的工况。  
   - 手动操作：标配手轮或手柄，结构紧凑，支持远程加装执行器扩展自动化控制。  

4. 穿透式阀体结构
   - 顶部穿透安装：阀盖可拆卸设计，无需拆除阀门即可快速更换闸板或密封件，大幅降低维护停机时间。  
   - 螺栓连接标准：法兰端符合GB、ANSI、DIN等标准，支持定制非标尺寸，适配全球管道系统。
