1. Flexible
The connection method of the flexible connection is to insert the pipe into the nozzle of the pipe fitting, tighten the nut with a wrench, and use a compression ring to align.
The sealing ring seals and then completes the connection. It is characterized by easy installation and can be disassembled at will, but the installation strip.
The rolling groove at the end of the piping must be fixed with a groove machine to the C-shaped groove.
2. Compression connections.
The method is to insert the pipe into the nozzle of the pipe fitting, fasten it with a nut, and use the screw force to pass the nozzle shell through the sealing ring.
Compress the seal and complete the connection. Fast installation and detachable, but relatively weak connection reliability, screws when vibrating.
The line is easy to loosen, causing the nut to tighten. Leakage occurs when seal pressure is reduced, a complex component.
High, it cannot be buried.
3. Flange connection.
(1) Flange connection.
Principle: The flange and the pipeline are welded by argon arc, fastened with quick clamps or bolts, and gaskets between the flanges.
4. Single-clamp connection.
The method is to insert the attachment into the attachment. The two ends of the accessory are protruding U-shaped grooves with built-in sealing rings, which are composed of special accessories.
The tool snaps into the connection and inserts the part.
5. Double press connection is an improved S-type press connection technology based on single press connection technology.
Features: Easy and fast installation, reliable sealing, anti-vibration, avoid joint loosening, short installation period and low cost.
Avoid quality defects caused by factors of consideration. The O-ring in the pipe fitting has a certain elasticity after being compressed.
Automatic compensation after expansion and cold contraction to ensure pipeline safety. The diameter of the clamping connection is less than or equal to 100mm.
Therefore, the double-press connection method is relatively simple, and the quality of the connection method is also relatively high.
