Product description

 

[working principle] sanitary quick installation butterfly valve is a kind of stainless steel valve which uses round butterfly plate as the opening and closing part and rotates with the stem to open, close and adjust the fluid channel. The butterfly plate of sanitary quick installation butterfly valve is installed in the diameter direction of pipeline. In the cylindrical passage of stainless steel butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is 0 °~ ninety ° Between, rotate to 90 ° The valve is fully open.

 

[application] the sanitary butterfly valve is specially used in dairy products, food, pharmacy, beer, cosmetics and other industries.

 

[note] all sanitary quick mounting butterfly valves are mirror polished in contact with the medium. Seal ring of sanitary quick assembling butterfly valve Ф 25- Ф There are two application ranges: EPDM, Si, Ф EPDM below 57

 

The opening and closing parts of sanitary quick installation butterfly valve rotate 90 degrees to and fro ° Left and right to open, close and regulate the flow channel of a stainless steel butterfly valve.

 

The sanitary quick installation butterfly valve is not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast in operation, but also has good flow regulation function and closing sealing characteristics. When the valve is fully opened, it has small flow resistance. When the valve is opened at about ° To 70 ° Therefore, in the field of large diameter regulation, the application of sanitary quick installation butterfly valve is very common; The movement of the valve plate of the sanitary manual quick mounting butterfly valve is wiping, so the sanitary quick mounting butterfly valve can be used for the medium with suspended fixed particles, and can also be used for powdery and granular media according to the strength of the seal.

 

Sealing of sanitary quick mounting butterfly valve:

 

Sanitary quick mounting butterfly valve is a kind of middle line stainless steel soft sealing butterfly valve. Its sealing principle is that when the valve plate of sanitary quick mounting butterfly valve is processed, its sealing surface should have appropriate surface roughness value, and when the synthetic rubber seat is molded, the sealing surface should have appropriate surface roughness value. When the stainless steel butterfly valve is closed, through the rotation of the valve plate, the cylindrical sealing surface of the valve plate squeezes the synthetic rubber seat to produce elastic deformation of the synthetic rubber seat. The elastic force is used as the sealing pressure to ensure the sealing of the valve

 

Advantages of sanitary quick installation butterfly valve:

 

1. The rubber seal ring and valve plate of sanitary quick installation butterfly valve are good, which ensure the service performance and service life of stainless steel butterfly valve

 

2. The sanitary quick mounting butterfly valve adopts high-precision CNC lathe to finish turning the valve body, which ensures the reliable interchangeability of stainless steel butterfly valve and avoids the trouble of replacing rubber and not ensuring its performance.

 

3. The valve stem of sanitary quick mounting butterfly valve is smooth, which reduces the friction force, so it can be opened flexibly and easily. The steel parts are made of stainless steel, and the rubber is made of food rubber, which has high sanitary quality.

 

4. The diameter of the valve body is equal to the inner diameter of the pipeline. When opening, the narrow and streamlined valve plate is consistent with the fluid direction. The flow is large and the resistance is small. There is no material accumulation. The handle adopts pull type and pull type, which can bear large operating torque and is not easy to break.

 

5. The opening and closing range of sanitary quick installation butterfly valve is 90 degrees, which can be fixed at the position of every 15 degrees. It is adjustable, fast opening and closing, and easy to operate.

 

6. The valve body of sanitary quick installation butterfly valve adopts detachable connection, with simple structure and convenient maintenance.

 

7. Sanitary butterfly valve is light and beautiful, with bright surface without dust and burr.

 

8. The sanitary butterfly valve has passed the tight strength and sealing test to ensure the quality.

 

9. The fatigue life test of sanitary quick mounting butterfly valve is not less than 30000 times, which ensures its service life.

 

Selection principle of sanitary manual quick installation butterfly valve:

 

Sanitary quick installation butterfly valve (middle line soft sealing butterfly valve) is suitable for fresh water, sewage, sea water, brine, steam, natural gas, food, medicine, oil, various acids and bases and other thin-walled pipelines that require complete sealing, zero leakage in gas test, high service life and working temperature from 10 ℃ to 150 ℃. The installation and maintenance of sanitary manual quick installation butterfly valve should pay attention to the following matters:

 

1. During installation, the disc should stop at the closed position. 2. The opening position should be determined according to the rotation angle of the butterfly plate
