Advantages and disadvantages of compressed air pipeline handle butterfly valve

The advantages and disadvantages of handle butterfly valves in compressed air pipelines can be summarised as follows:

Pros:

1. Compact structure and small volume: butterfly valve occupies little space due to its design features, which is very suitable for use in space-restricted occasions.

2. Fast and convenient operation: the handle butterfly valve can be opened and closed quickly, the operating torque is small, easy to operate, suitable for occasions that require frequent opening and closing.

3. Precise flow control: the opening angle of butterfly valve is large, usually 90 degrees, which makes the gas flow control more precise.

4. Small fluid resistance: when opening, the fluid resistance of butterfly valve is relatively small, and the operating pressure is relatively low.

5. Convenient installation: butterfly valve can be installed in any position, easy maintenance, sealing parts can be replaced, sealing performance is reliable to achieve two-way sealing zero leakage.

Disadvantages:

1. sealing performance is relatively poor: compared with other valves such as ball valves, gate valves, butterfly valves in high-pressure, high-temperature, high-viscosity fluid conditions are prone to leakage or leakage phenomenon.

2. Short service life: butterfly valve valve flap is usually made of rubber or plastic material, easy to be worn in operation, corrosion and other effects, thus shortening its service life.

3. High operating skills: butterfly valves require certain skills in operation, if improper operation can easily lead to premature damage to the butterfly valve, increasing the cost of maintenance and replacement.

4. Weak pressure resistance: Butterfly valves need special attention in the use of high-pressure situations, and their pressure resistance is relatively weak.

5. Application scenarios are limited: due to the structural characteristics of the butterfly valve, its application scenarios relative to other valves are subject to certain restrictions, the need to consider the material of pipeline equipment, pressure and other factors.

In summary, the handle butterfly valve in the compressed air pipeline has its unique advantages, such as compact structure, fast and convenient operation, precise flow control, etc., but there are also relatively poor sealing performance, short service life and other shortcomings. When choosing to use, you need to weigh and choose according to the specific application scenarios and requirements.
