一、进口直埋式软密封闸阀概述

进口直埋式软密封闸阀，Buried type soft sealing gate valve，也叫地埋式软密封闸阀，阀门可直接埋入地下，不用垒砌窨井，减少了路面开挖的面积；极小的井室可保持路面美观，降低施工难度，减少工程造价。直埋式软密封闸阀分伸缩式和微调固定式两种，其中伸缩式又分金属型和塑料型。在施工过程中，伸缩式可根据阀门埋设深度与地面之间的距离作大范围任意调节，微调固定式可现场微量调节。

美国威盾VTON直埋式软密封闸阀具有长期使用不泄漏、免维护等优点，还可有效避免他人随意开关阀门和偷盗井盖。广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、冶金、能源系统等流体管线上作为调节和截流装置使用。

Directly buried soft seal gate valve, Buried type soft sealing gate valve， Also known as buried soft seal gate valve, the valve can be directly buried underground without the need for manhole construction, reducing the area of road excavation; The extremely small well chamber can maintain the appearance of the road surface, reduce construction difficulty, and reduce project costs. There are two types of directly buried soft sealed gate valves: telescopic and fine tuned fixed, among which the telescopic type is further divided into metal type and plastic type. During the construction process, the telescopic type can be adjusted over a wide range according to the distance between the buried depth of the valve and the ground, while the fine tuned fixed type can be adjusted slightly on site.

The American shield VTON buried soft seal gate valve has the advantages of long-term use without leakage and maintenance, and can effectively prevent others from opening and closing the valve arbitrarily and stealing manhole covers. Widely used as a regulating and intercepting device in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, ships, metallurgy, energy systems, etc.

1. Flat bottomed valve seat, no accumulation of dirt, making the seal more reliable

2. The valve disc is wrapped in nitrile rubber as a whole

3. The internal components of the valve are made of corrosion-resistant and stainless steel and copper alloy materials. The directly buried soft sealed gate valve can be used in sewage systems to adapt to harsh working environments

4. Small size, light weight, easy to install and maintain

5. The valve stem adopts three O-ring seals, greatly reducing friction resistance during switching, and the switch is lightweight and leak free.
