Application of gate valve in the field of water supply industry

Gate valve, one of the water series valves, is a product often used in the water supply industry.

Gate valve can only be fully open or fully closed, used to cut off the flow of water in the water supply pipeline. Generally in the water supply network in the soil depth impact is small, the choice of gate valve. As we all know, there is a class of valves with functions very similar to gate valves, that is, butterfly valves; because butterfly valves and gate valves can play the same role of switching and regulating the flow, the price of butterfly valves under the same specifications will generally be lower than gate valves. Therefore, we also use butterfly valves in water supply pipes to reduce the depth of the pipe cover with a large pipe diameter.

However, we found through a lot of data analysis and feedback from our customers that butterfly valves have far more failures than gate valves in the process of use.

Therefore, the gate valve is the best choice for the use of valves in the water supply pipeline!

 

In order to make the gate valve better used in the water supply industry, in recent years, as a leader in the domestic valve manufacturing brand, WESDOM is also actively developing and manufacturing soft seal gate valves.

The general gate valve used in the market for a long time, there is a general leakage, easy to rust phenomenon, wesdom introduced foreign advanced technology produced by the soft seal gate valve. Overcome the general gate valve poor sealing, elastic fatigue, easy to rust, and other defects. Soft seal gate valve is the replacement of the traditional gate valve, the use of elastic gate plate to produce a micro-deformation compensation effect, to achieve the good sealing effect, the valve has a light switch, reliable sealing, good elastic memory, and long service life and other significant advantages, can be widely used in water, sewage, construction, food, electricity, medicine, metallurgy, light textile, energy systems, and other fluid pipelines as a regulating and intercepting device. The soft seal gate valve has more advantages than the traditional gate valve.

Soft seal gate valve features advantages as follows.

①Flat bottom type valve seat

Traditional gate valves are often washed in the water that is due to foreign objects such as stones, wood, cement, paper, debris and other silt accumulation in the groove at the bottom of the valve, easy to close the tight and form a leak phenomenon. The bottom of the soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause the accumulation of debris and make the fluid flow smoothly.

②Whole rubber cover

The valve adopts high-quality rubber for overall internal and external rubber covering, the domestic first-class rubber vulcanization technology makes the vulcanized valve can ensure precise geometry, and the rubber and ductile iron valves are firmly attached, not easy to fall off, and have good elastic memory.

③Corrosion resistance

The valve body is painted with powder epoxy resin, which can prevent corrosion and rusting of the valve body. And can be used in the sewage systems. The traditional cast iron gate valve is often broken due to foreign objects hitting, colliding, or overlapping. Since the body is made of ductile iron, this situation has been greatly reduced.

④Three "O" type

The stem is designed with a triple "O" ring seal. This reduces the frictional resistance when opening and closing, significantly reducing the phenomenon of water leakage and allowing the seal ring to be replaced without stopping the construction of water.

⑤It helps to drink

Since the valve body is painted with non-toxic epoxy resin, the internal and external surfaces of the gate valve are completely covered with rubber without rusting or corrosion and can be used for drinking.

⑥Precision casting valve body

The valve body is precision cast, the precise geometry makes the northern part of the valve body without any finishing process to ensure the sealing of the valve.

⑦Light weight

The body is made of ductile ink casting, the weight is reduced by about 20 to 30 percent compared with the weight of a traditional gate valve, which is convenient and easy to maintain.
