Valve connection type - threaded connection

This is a simple connection method and is often used for small valves. There are two situations:

1, direct seal: internal and external threads directly from the sealing effect. In order to ensure that the connection is not leaky, it is often filled with lead oil, string hemp, and PTFE raw material tape; among them, PTFE raw material tape is widely used; it has good corrosion resistance and sealing effect It is easy to use and save, and it can be completely removed when it is disassembled, because it is a non-sticky film that is much superior to lead oil and wire.

2. Indirect sealing: The force of thread tightening is transmitted to the gasket between the two planes to allow the gasket to function as a seal.
