Usage and precautions of quick connector
Views:2260 Date:2020-04-30
Quick connector; a connector that can connect or disconnect pipes without tools.
1. According to the usage form, it can be divided into:
Quick coupling for air, quick coupling for oxygen fuel gas, quick coupling for gas and liquid, quick coupling for oil pressure, quick coupling for inert gas, quick coupling for cooling water temperature oil, semiconductor quick coupling.
1. Quick connector for air:
Mainly used for air piping and pneumatic tool accessories. Corresponding to its use, there are a variety of body materials, sizes and installation shapes.
Precautions for use:
Note
L Do not use it for applications other than quick fluid couplings.
L Please do not use it for fluids other than applicable fluids.
L Please do not connect with quick fluid couplings made by other companies.
L Do not exceed the maximum working pressure when using.
L Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material.
L Do not hit, bend, or stretch artificially to prevent damage.
L Do not use it in the place mixed with metal powder or sand, etc., to prevent poor work or leakage.
L If debris adheres, it may cause poor work or leakage.
L Do not disassemble the quick connector.
2. Quick connector for oxygen and fuel gas:
It is mainly used for piping of general-purpose fuses, and has the characteristics of large flow, durability and corrosion resistance. The main body material, size and installation shape are rich and diverse.
Precautions for use:
Warning
L Fluid must flow from the sleeve side to the plug side.
L Please use the sealing material for the external thread of regulated thread.
L When installing the thread, do not exceed the maximum tightening torque to prevent damage.
L Do not use it for applications other than quick fluid couplings.
L Please do not use it for fluids other than applicable fluids.
L Please do not connect with quick fluid couplings made by other companies.
L Do not exceed the maximum working pressure limit when using.
L Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material.
L Do not hit, bend, or stretch artificially to prevent damage.
L Do not use it in the place mixed with metal powder or sand, etc., to prevent poor work or leakage.
L If debris adheres, it may cause poor work or leakage.
L Please don't use it in the place where gas stays.
L Do not carry out loading and unloading operations when there is an open flame nearby.
L If a flashback occurs, please replace it with a new one.
L When installing the hose, never get oil on it to prevent spontaneous fire.
L When installing the hose again, cut the end of the hose from more than 3 cm.
Note
L Do not use it for applications other than quick fluid couplings.
L Insert the hose firmly into the root of the interface and fix it with a hose belt or nut.
L In order to prevent the possession of water, it should be kept indoors.
L Do not use cracked hoses to prevent leaks and falling off.
L Leak check should be done before use. If there is a leak, stop using it immediately and replace it with a new one.
L Make sure that the torch valve is closed before connecting.
3. Gas and liquid common quick connector:
It is mainly used in the piping of ion cooling device, wine making device, cutting oil piping of working machine, car washing machine. Through simple lever operation connection, liquid, gas, powder, etc. can be transported. The main body material, size and installation shape are rich and diverse.
Precautions for use:
Warning
L Please do not use it for fluids other than applicable fluids.
L Do not exceed the maximum working pressure when using.
L Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material.
L Do not disassemble
Note
L Please use the sealing material for the external thread of regulated thread.
L During installation, the applied torque should not exceed the maximum torque to prevent damage.
L Please do not use it for applications other than quick connectors.
L Please do not connect with quick fluid couplings made by other companies.
L Do not hit, bend, or stretch artificially to prevent damage.
L Do not use it in the place mixed with metal powder or sand, etc., to prevent poor work or leakage.
L If debris adheres, it may cause poor work or leakage.
L The brake valve must be installed before the quick connector.
L Please do not use it as a hinge joint.
L If used in machines with vibration or shock, the durability will be reduced.
L Do not use water and glycol series media for steel and iron quick couplings. The zinc coating on the surface will dissolve.
L The fluid used is a clean fluid filtered by a filter.
L The “O” sealing ring must always be kept with oil.
L Refer to the content at the end of this precaution to confirm the sealing material and body material suitable for the fluid.
4. Quick connector for hydraulic:
Mainly used in hydraulic equipment and construction machinery. The main material should be made of metal that can resist vibration and impact. The size and installation shape are rich and varied.
