一、进口暗杆软密封闸阀概述

进口暗杆软密封闸阀，Dark bar soft sealing gate valve，是指采用弹性阀瓣与阀体直接密封，利用橡胶的弹性变形达到补偿作用，达到良好的密封效果的闸阀。

暗杆软密封闸阀：阀杆螺母在阀体内，与介质直接接触。开闭闸板时，用旋转阀杆来实现。这种结构的优点是：闸阀的高度总保持不变，因此安装空间小，适用于大口径或对安装空间受限制的闸阀。此种结构要装有开闭指示器，以指示开闭程度。

美国威盾VTON暗杆软密封闸阀平底式设计，确保较小的水头损失，防止杂物留存，该阀可以广泛地应用于建筑、消防、自来水、食品、医药、化工行业。

Non rising soft seal gate valve, Dark bar soft sealing gate valve， It refers to a gate valve that uses an elastic valve disc to directly seal the valve body, and uses the elastic deformation of rubber to achieve compensation and achieve good sealing effect.

Non rising soft seal gate valve: The valve stem nut is located inside the valve body and in direct contact with the medium. When opening and closing the gate, rotate the valve stem to achieve this. The advantage of this structure is that the height of the gate valve remains constant, so the installation space is small, making it suitable for gate valves with large diameters or limited installation space. This structure should be equipped with an opening and closing indicator to indicate the degree of opening and closing.

The flat bottomed design of the American Weidun VTON concealed soft seal gate valve ensures small head loss and prevents debris retention. This valve can be widely used in the construction, fire protection, tap water, food, medicine, and chemical industries.

三、进口暗杆软密封闸阀产品特点
1. 整体包胶：软密封闸阀闸门采用整体包胶，其良好的覆盖性能与精确的几何尺寸，保证密封可靠，寿命。
2. 重量轻：阀体采用球铁制成，重量轻，安装方便。
3. 平底阀座：底部采用与水管相同的平底式阀座设计，不产生杂物淤积，密封更可靠。
4. 耐腐蚀：闸阀内腔采用无毒环氧树脂涂状，防止腐蚀和生锈，不但可供生饮，而且可用于污水系统。
5. 三“0”密封：阀杆采用三道0型环密封，磨擦阻力小，开关轻巧，不漏水。

1. Overall encapsulation: The soft sealing gate valve gate adopts integral encapsulation, which has good coverage performance and precise geometric dimensions, ensuring reliable sealing and service life.

2. Lightweight: The valve body is made of ductile iron, which is lightweight and easy to install.

3. Flat bottomed valve seat: The bottom adopts the same flat bottomed valve seat design as the water pipe, which does not produce debris accumulation and provides a more reliable seal.

4. Corrosion resistance: The inner chamber of the gate valve is coated with non-toxic epoxy resin to prevent corrosion and rust. It can not only be used for drinking, but also for sewage systems.

5. Three "0" seals: The valve stem adopts three "0" ring seals, with low friction resistance, lightweight switch, and no water leakage.
