Operation method of quick connector connection and disassembly:
The permanent quick connector consists of connector shell, inner O-ring, outer O-ring, isolating ring, outer retaining ring and self-locking buckle. When another pipeline adapter (male connector) is inserted into the connector, the self-locking buckle has certain elasticity,
The two connectors can be connected together with the snap fastener, and then pulled back to ensure the installation in place, so that the quick connector can work. During maintenance and disassembly, push the male connector first and then press and hold the buckle button at both ends of the self-locking buckle,
By expanding the middle of the self-locking buckle, the connector can be easily pulled out, and SAE 30 heavy oil shall be used for lubrication before re connecting.
Patent: a pipeline quick connector, patent No.: ZL 201020517129.7
Independent development and creativity: a nylon alloy with high heat resistance and its preparation method patent No.: 201110107011.6
Security:
The quick joint adopts double sealing ring radial sealing structure, and the inner O-ring adopts modified rubber, which is mainly customized for various physical and chemical properties of the fluid to prevent aging, corrosion, swelling, etc.; the outer O-ring is separated by intermediate isolation ring,
The two sealing rings have corresponding moving space without rubber matrix bonding. The outer O-ring adopts synthetic rubber to enhance mechanical properties and prevent air aging. The sealing ring and the isolating ring are firmly fixed in the
In the shell, the sealing ring will not fall off or shift. Greatly ensure the safety of the seal.
Working environment of quick connector:
a. Gasoline and diesel delivery system, or methanol, ethanol, natural gas delivery system, or its steam emission or volatilization control system.
b. Operating pressure up to 500 kPa, 5 bar, (72 psi)
b. Operating vacuum as low as - 50 kPa, - 0.55 bar, (- 7.2psig)
b. Operating temperature range - 40 ℃ (- 40 ° f) to 115 ℃ (- 239 ° f), short time 150 ℃
There are various "fir tree" options for the connection end of the permanent quick connector and the pipe:
