U-shaped flange butterfly valve is a common channel valve. Due to its unique U-shaped design and effective operating performance, it occupies an important position in artificial channel systems. This composition will explore its working principle, advantages and disadvantages, and diurnal conservation points in depth to help you more understand and use this valve.
I. Introductory structure of U-shaped flange butterfly valve
The U-shaped flange butterfly valve consists of a main body, a butterfly plate, a valve seat, a U-shaped flange, a drive medium and other corridor. The butterfly plate is fixed by a U-shaped flange. The valve can be opened and closed by rotating 90 degrees, and the fluid flows easily through the center orifice of the valve body.
II. Working principle and advantages
The working principle is simple when the butterfly plate rotates, the U-shaped flange forms a channel to allow the medium to pass; when the butterfly plate is closed, the U-shaped structure can effectively help leakage and give good sealing. The main advantage of the U-shaped design is that it can maintain a stable pressure difference indeed at large inflow rates, and it’s easy to install and disassemble, which is accessible for conservation.
III. Features
1. Compact structure
The U-shaped butterfly valve adopts a U-shaped valve body, which makes the overall structure of the valve more compact, occupies a small area, and is easy to install and maintain.
2. Double seal
The sealing face of the U-type butterfly valve adopts a double seal design, that is, two sealing rings are set between the valve seat and the butterfly plate, which effectively improves the sealing performance of the valve and reduces the possibility of leakage.
3. Small inflow resistance
The inflow channel of the U-type butterfly valve is U-shaped, and the resistance of the fluid when flowing inside the valve is small, so it has better inflow performance.
4. Noise reduction and vibration reduction
The design of the U-type butterfly valve takes into account the inflow characteristics of the fluid. By optimizing the shape of the inflow channel, the turbulence and eddy current of the fluid inside the valve are reduced, thereby reducing noise and vibration.
5. Wear resistance
The sealing face and inflow channel of the U-type butterfly valve are made of wear and tear- resistant accoutrements, which are suitable for media containing solid patches and increase the service life of the valve.
IV. Operation scripts
U-type flange butterfly valves are extensively used in chemical, petroleum, electric power, metallurgy and other diligence, especially in occasions where frequent switching and high sealing conditions are needed, similar as water treatment, brume channels, gas transportation, etc.
V. Conservation and care
In order to insure the long-term operation of the U-type flange butterfly valve, regular examination is essential. The examination content includes whether the valve slice is worn, whether the U-shaped flange sealing face is complete, and whether the drive medium is flexible. Clean the inner and external shells of the valve body to avoid contaminations from accumulating and affecting the valve performance. At the same time, slick the drive factors regularly to help rust.
VI. Preventives and Troubleshooting
During operation, avoid inordinate gyration of the butterfly plate to help damage to the sealing components.However, you should close the valve first, and also find the cause, If you encounter a problem of valve jamming or leakage. You may need to replace the worn corridor or acclimate the sealing parameters.
VII. The difference between U-type butterfly valve and double flange butterfly valve
- Different applicable pressures. The U-type butterfly valve is a sealing element with a simple structure and small size, suitable for medium and low pressure ranges, suitable for gas, water and some weakly sharp media. The double flange butterfly valve has flange connectors installed at both ends of the valve body, which makes it stronger and can be used for high- pressure, high- temperature media and largely sharp media.
2. Different installation styles. The U-type butterfly valve is installed in a ferrule type, which is generally more accessible to install and disassemble. The connection system of the double flange butterfly valve is to connect the flange to the channel, which requires professional technology to install and disassemble.
VIII. Summary
U-type butterfly valve has shown great operation eventuality under special working conditions with its unique structure and excellent performance. With the nonstop advancement of artificial technology, the operation compass of U-type butterfly valve will be further expanded, furnishing more effective and dependable fluid control results for colorful diligence. Correct selection and use of U-type butterfly valve will help ameliorate the operating effectiveness of artificial systems, reduce conservation costs, and insure product safety.
