Check Valve Connection Methods and Advantages and Disadvantages

In the piping system, check valve is a very important valve, used to prevent fluid backflow. There are many different ways to connect check valves, each of which has its own characteristics and scope of application. In this article, we will introduce several common WKT factory check valve connection methods and their respective advantages.

Flange connection

Flange connection is one of the most common connection methods for check valves. It fixes the check valve and pipeline together through flange and bolt. The advantages of this type of connection are that it is suitable for large piping systems, has high connection strength and good sealing performance, and can withstand high pressure. In addition, the flange connection is easy to install and remove, allowing for quick replacement of check valves. However, its disadvantage is that the connection size is large and requires special flanges and bolts, which are costly.

Advantages

Suitable for large piping systems with high connection strength.

Easy to install, can be quickly dismantled and replaced.

Good sealing performance, can withstand higher pressure.

Disadvantages

Larger connection size, occupies more space.

Requires special flanges and bolts, higher cost.

Clamp connection

The butt-clamp connection is suitable for small piping systems and is characterised by its compact structure. This type of connection does not require flanges and bolts, and is simple and easy to install. The advantage of the butt-clamp connection is that it has good sealing performance and can withstand a certain amount of pressure. However, it is suitable for small-diameter pipelines, not for large-diameter pipelines, and the strength of the connection is relatively low, not suitable for high-pressure pipelines.

Advantages

Suitable for small piping systems with compact structure.

Simple installation, no need for flanges and bolts.

Good sealing performance and can withstand certain pressure.

Disadvantages

Suitable for small diameter pipelines, not suitable for large diameter pipelines.

Relatively low connection strength, not suitable for high pressure pipelines.

Threaded connection

Threaded connection is suitable for low-pressure, small-diameter piping system. It has the advantages of easy installation, no need for special tools and low cost. However, the disadvantages of threaded connection are relatively low connection strength, not suitable for high-pressure pipelines, and poor sealing performance, easy to leak.

Advantages

Suitable for low-pressure, small-diameter piping systems.

Easy to install, no special tools required.

Low cost and economical.

Disadvantages

Relatively low connection strength, not suitable for high pressure pipelines.

Poor sealing performance, prone to leakage.

Welded connection

Welded connections are suitable for piping systems with high temperature, high pressure or special fluids. It has the advantages of high connection strength, good sealing performance and is suitable for underground piping systems without the need for flanges and bolts. However, the welding process is complicated and requires specialised skills, the connection size is larger, takes up more space, is more costly and difficult to maintain.

Advantages

Suitable for piping systems with high temperature, high pressure or special fluids.

High connection strength and good sealing performance.

Suitable for underground piping systems, no need for flanges and bolts.

Disadvantages

Complicated welding process, requiring specialised skills.

Larger connection size, occupies more space.

Higher cost, difficult to maintain.

Socket connection

Socket connection is suitable for underground piping system without flanges and bolts. Its advantages are easy installation, no special tools, good sealing performance, and can withstand a certain pressure. However, socket connection is suitable for small diameter pipelines, not suitable for large diameter pipelines, and the connection strength is relatively low, not suitable for high pressure pipelines.

Advantages

Suitable for underground piping system, no need for flanges and bolts.

Easy to install, no need for special tools.

Good sealing performance, can withstand a certain pressure.

Disadvantages

Suitable for small diameter pipelines, not suitable for large diameter pipelines.

Relatively low connection strength, not suitable for high pressure pipelines.

Quick connection

Quick connection is suitable for piping systems that require quick disassembly and installation. Its advantages are easy installation, no need for special tools, good sealing performance, and can withstand a certain pressure. However, the disadvantage of quick connection is that the connection strength is relatively low, not suitable for high-pressure pipelines, and the cost is high, so the economy is poor.

Advantages

Suitable for piping systems that require quick disassembly and installation.

Easy to install, no special tools required.

Good sealing performance and can withstand certain pressure.

Disadvantages

Relatively low connection strength, not suitable for high pressure pipelines.

Higher cost, less economical.

Conclusion

When choosing the connection method of custom check valve, the appropriate connection method should be chosen according to the specific needs of the piping system, such as pipeline size, pressure level, fluid characteristics and so on. Only by choosing the appropriate connection method can we ensure the stable operation of the piping system.
