LKJ Ultra-High Pressure Quick Connector (Shenfei Type)

Product Material: Female: Carbon Steel / Male: Carbon Steel /

Product Description: Ultra-high pressure quick connector (supplied for Shenyang Aircraft Factory)

Product Application: LKJ connectors are suitable for situations where hydraulic transmission pipelines need to be connected and disconnected due to equipment operation or maintenance, without fluid loss. They are widely used in various industrial connections, such as ultra-high pressure separable hydraulic pipelines, connectors between equipment, jacks, or bridge construction equipment. They are also specialized connectors for 70Mpa pressure testing grease injection dual-purpose guns (pressure sealing tools, grease injection guns).

The connecting threads at both ends can be customized according to user requirements.

Hydraulic pipe fittings are important components in hydraulic systems for connecting hydraulic pipelines, enabling fluid transmission and energy conversion. There are numerous types of hydraulic pipe fittings, and for beginners, identifying different types can be challenging. This article will detail the common types and identification methods of hydraulic pipe fittings to help readers better understand and use them.

Basic Concepts of Hydraulic Pipe Fittings

Hydraulic pipe fittings refer to components used to connect hydraulic pipelines, enabling fluid transmission and energy conversion in hydraulic systems. They typically consist of the fitting body, sealing elements, and connecting threads. The main function of hydraulic pipe fittings is to connect hydraulic pipelines, ensuring the proper operation of the hydraulic system.

Common Types of Hydraulic Pipe Fittings

There are many types of hydraulic pipe fittings, with the following being the most common:

1. Threaded Hydraulic Pipe Fittings: Threaded hydraulic pipe fittings are the most common type, connecting hydraulic pipelines via threads. Common threaded fittings include NPT, BSP, and JIC, which are used in different countries and regions.

2. Flange-Connected Hydraulic Pipe Fittings: Flange-connected hydraulic pipe fittings connect hydraulic pipelines via flanges and typically consist of the flange body, sealing gaskets, and bolts. They are suitable for applications requiring higher connection strength and sealing performance.

3. Clamp-Connected Hydraulic Pipe Fittings: Clamp-connected hydraulic pipe fittings connect hydraulic pipelines via clamps and typically consist of the clamp body, sealing gaskets, and bolts. They are suitable for applications requiring quick and convenient disassembly.

4. Quick Connectors: Quick connectors connect hydraulic pipelines rapidly and typically consist of the quick connector body and sealing elements. They are suitable for applications requiring frequent disassembly and connection, improving work efficiency.

Identification Methods for Hydraulic Pipe Fittings

Different types of hydraulic pipe fittings can be identified using the following methods:

1. Appearance Features: Different types of hydraulic pipe fittings may have variations in appearance, such as the shape and number of threads on threaded fittings or the shape and aperture of flanges on flange-connected fittings. Observing these features can provide an initial judgment of the type.

2. Dimensional Parameters: The dimensional parameters of hydraulic pipe fittings are also crucial for identification. Different types may vary in dimensions, such as thread diameter and pitch for threaded fittings or flange aperture and bolt hole spacing for flange-connected fittings. Measuring these parameters can accurately determine the type.

3. Identification Codes: Some hydraulic pipe fittings have identification codes. By referring to relevant standards and specifications, the corresponding type information can be found. For example, identification codes on threaded fittings may include thread type, diameter, and pitch, while flange-connected fittings may include flange aperture and bolt hole spacing.

Hydraulic pipe fittings are essential components in hydraulic systems for connecting pipelines. Identifying different types requires observing appearance features, measuring dimensional parameters, and consulting identification codes. Mastering the common types and identification methods of hydraulic pipe fittings can help readers better understand and use them, improving the efficiency and safety of hydraulic systems.
