Quick connectors can be divided into: quick connectors for air, quick connectors for oxygen fuel gas,

 

Common quick connectors for gas and liquid, hydraulic quick connectors, inert gas quick connectors,

 

Quick connectors for cooling water temperature and oil, and semiconductor quick connectors. Here we mainly introduce the lever type quick connectors used in the petrochemical industry.

 

【product type】

 

Lever type quick connectors are divided into:

 

KJT-A type B type C type D type E type F type DC type DP type and 9 non-standard types,

 

There are 4 male connectors including type A, type E, type F, and type DP.

 

4 female connectors of type B, type C, type D and type DC.

 

Lever type quick connectors are divided into: according to material:

 

Stainless steel lever type quick connector

 

Brass lever type quick connector,

 

Category 4 aluminum alloy lever type quick connectors and plastic lever type quick connectors.

 

【Technical Parameters】

 

Manufacturing materials: 304 316 aluminum alloy brass plastic

 

Nominal diameter: DN15-DN150mm

 

Nominal pressure: 16-64KG

 

Applicable temperature: -20~150℃

 

Applicable media: water, oil, gas and some corrosive liquids.

 

Scope of application: industry, chemical industry, liquefied petroleum gas, vehicle and ship manufacturing equipment, etc.

 

Connection method: thread, welding, flange, quick connect, lever type, etc.

 

【Features】

 

1. Save time and effort: When disconnecting and connecting oil lines through quick connectors, the action is simple, saving time and manpower.

 

2. Fuel saving: When the oil line is broken, the single valve on the quick connector can close the oil line and the oil will not flow out, thus avoiding the loss of oil pressure.

 

3. Environmental protection: When the quick connector is broken and connected, the oil will not leak, protecting the environment.

 

4. The equipment is uniquely designed and easy to transport: Large equipment or hydraulic tools that need to be easy to carry can be disassembled and transported using quick connectors, and then assembled and used after arriving at the destination.

 

5. Economy: All the above advantages create economic value for customers.

 

 

 

【Selection Principle】

 

1. The type and temperature of the fluid (please select the body material and sealing material of the quick connector that are suitable for the type and temperature of the fluid)

 

Depending on the fluid, the suitable body material and sealing material are different. For example, quick connectors are air. It is recommended to use steel. For water, choose brass or stainless steel.

 

2. Liquid pressure (please select a quick connector with pressure resistance suitable for the fluid pressure)

 

The pressure of the fluid is also the key to selecting a quick connector.

 

3. The use environment of the quick connector (please select a quick connector with a structure and material suitable for the use environment)

 

The type, body material, and sealing material of the quick connector should be considered based on the humidity conditions, dust conditions, and the use environment that is prone to corrosion.

 

4. Confirm that the selected quick connector connection threads must be consistent

 

When using products of different brands, it is best to use the female and male heads of the same brand together. If cross-use is necessary, it is best to consult the technical personnel of the product supplier before use and confirm before use.

 

5. Installation shape and size (please order the product after confirming the final shape and size)

 

Please determine the model and material of the quick connector, and specify the assembly shape and size corresponding to the piping characteristics. Please note that dimensions are relative to fluid flow.

 

【Precautions】

 

1. Please do not use it with fluids other than applicable fluids.

 

2. Do not exceed the maximum operating pressure limit when using it.

 

3. Do not use it outside the operating temperature range to prevent wear or leakage of the sealing material.

 

4. Do not hit, bend, or stretch artificially to prevent damage.

 

5. Do not use it in places where metal powder or sand dust is mixed to prevent malfunction or leakage.

 

6. When installing threads, do not exceed the maximum tightening torque to prevent damage.

 

7. Do not use hoses with cracks to prevent leakage or falling off.

 

8. If used in machines with vibration and impact, the durability will be reduced.

 

9. The fluid used must be clean fluid filtered by the filter.

 

10. Do not disassemble the quick connector.
