Hygienic level of water pipes directly affects the quality of water. Hygienic level of water supply pipes is very different from that of drainage pipes.
For the sake of the health of our family and ourselves, we all want safe and sanitary drinking water equipment.
Therefore, sanitary valves are indispensable. The reasons are as follows:
1. Material safety
The material of sanitary grade valves is stainless steel, because stainless steel contains chromium and forms a very thin chromium film on the surface. This film separates from the oxygen intruded into the steel and acts as corrosion-resistant steel, which can resist corrosion in air or chemical corrosive medium. It has a beautiful surface and good corrosion resistance. It does not need surface treatment such as color plating to exert its inherent surface.
2. Corrosion resistance
In order to maintain the inherent corrosion resistance of stainless steel ball valves or fittings, steel contains more than 12% chromium. Health grade fittings have good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties.
If it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion.
3. Widely used
It is suitable for food processing, storage, and transportation. Sanitary-grade valves have good processability and weldability.
4. Easy maintenance
Because stainless steel hygienic grade fittings are durable and hardly need to maintain the surface, people pay more attention to their application than ever before.
How can sanitary valves be used in drinking water projects?
The cock valve is a kind of rotary valve with closing parts or plunger shape. By rotating 90 degrees, the opening on the plug and the opening on the valve body are identical or separated, so as to open or close the valve. The shape of the plug of the cock valve can be cylindrical or conical. In a cylindrical plug, the passage is usually rectangular; in a conical plug, the passage is trapezoidal. These shapes make the structure of the cock valve lighter, but at the same time, they also cause some losses.
Cock valves are suitable for cutting off and connecting media and diversion, and sometimes for throttling.
Because the movement between the sealing surfaces of the cock valve has wiping effect, and the contact with the flowing medium can be completely prevented when the sanitary check valve is fully opened, it can also be used in the medium with suspended particles.
Another important feature of the cock valve is that it is easy to adapt to multi-channel structure, so that a valve can obtain two, three, or even four different runners such as 3-way ball valve. This can simplify the design of the pipeline system, reduce the use of valves and some of the connecting parts needed in the equipment.
