There are pros and cons to everything, and valves are no exception.Ball valve in the valve is more commonly used, but also our company's flagship product.So let's talk about, what are the advantages and disadvantages of the ball valve？
First, the advantages:
1. The flow resistance coefficient of the ball valve is relatively small compared to other valves.In particular, full-flow ball valves: the diameter of the ball valve does not decrease, which is equal to the resistance in the channel is equal to the pipe diameter, only a very small part of the resistance is caused by the friction of the pipe.
2. When the ball valve is opened and closed, it is fully open and fully closed, which leads to the isolation between the sealing surface of the ball and the valve seat and the circulation medium, so when the medium passes through the valve at high speed, it will not cause the erosion of the sealing surface, so the life of the valve is relatively long;It is the same reason, so the working medium can be on both sides of the seal, reliable
3. From the structure of the welded valve body, the symmetry of the valve body, resulting in the valve can fully withstand the stress from the pipeline, the same other valves are relatively compact structure, weight is also relatively light, very suitable for use in low-temperature media.
4. From the valve's closing parts, the ball valve opens and closes relatively quickly;And because it is a spherical closing member, it can be automatically positioned at the boundary position to withstand the high pressure difference caused by the closing.
Next, let's talk about the disadvantages of the ball valve:
1. Obviously, the first point is its most obvious disadvantage and cannot be used as throttling
2. From the material of the seat sealing ring, because the seat sealing ring is PTFE, so according to its physical characteristics, its coefficient of expansion and poor thermal conductivity, leading to its limitations, such as: the use temperature needs to be less than 180 degrees Celsius, more than this temperature sealing material is easy to aging.
3. Considering the appearance of the valve handle, when installing the ball valve, it is necessary to leave a rotating position for it.
The above is the ball valve, the general advantages and disadvantages of the integration, all the advantages and disadvantages, as long as it is in line with the conditions of reasonable use, I believe that the advantages are greater than the disadvantage
