Quick coupling specifications and selection conditions

The common quick coupling is a spare part product for connecting pipes. There are many different types of quick connectors on the market. They can be classified according to size specifications, and the corresponding models and names are also different. We should have a specific understanding of the different quick couplings, and we should also refer to the specifications between the pipe and the interface for proper matching. Next, let's take a look at what are the specifications of the quick connector!

Quick connector specifications

In general, the difference in the specifications of the quick connector of the water pipe generally refers to the difference of its interface. The interface specifications generally exist in 1/2, 3/4 (4 points, 6 points). When you buy, you must pay attention to whether the interface can match the water pipe or water gun interface that you need to install the connector, so as not to cause inconsistencies, you need to exchange or return the trouble. Others use stainless steel quick connectors. A type quick connector is a simple description: A type quick connector is a male head, it has no lugs on both sides, and the connection of one end is directly locked with the female head with lugs. One end is internally threaded. Brief description of B-type quick connector: B-type quick connector has a pull ear at each end, which belongs to the female head. One end of it is directly connected to the male head, and the other end is externally threaded. Brief description of the C-type quick connector: The C-type quick connector has two lugs and belongs to the female head. It is directly clamped with the male head at one end, and the other end is directly inserted into a hose (leather tube). The quick coupling is called the quick coupling of the hose or the quick coupling of the hose.

Selection conditions for quick connectors

1. Type and temperature of fluid

To select the quick connector of the body material and sealing material suitable for the type of fluid and temperature. According to the fluid, the proper body material and sealing material are different. For example, the quick connector is air. Steel is recommended, but brass or stainless steel is recommended for water.

2. The pressure of the liquid

To select a quick connector suitable for the pressure resistance of the fluid pressure, the pressure of the fluid is also the key to selecting the quick connector. The quick connector for oil pressure is 5.0Mpa (51kgf / cm2;)-68.6Mpa (700kgf / cm2;) to form a series, corresponding to the pressure characteristics, the structure of the quick connector is also different.

3. Structure of automatic switch valve

To select a quick connector for the valve structure suitable for piping applications. For the structure of the valve, there are two-way switch type, one-way switch type and two-way open type. In addition to the two-way switch type, fluid flows out of the piping during separation. So please pay attention.

4. Use environment of quick coupling

To select a quick connector that is suitable for the construction and material of the environment. The type, body material, and sealing material of the quick connector are selected in consideration of the humidity conditions of the use environment, the dust conditions, and the use environment prone to corrosion.

5. Confirm that the connection thread of the selected quick connector is consistent

In the process of using products of different brands, it is best to use the female and male heads of the same brand together. If they must be used cross-wise, it is best to consult the technical staff of the product supplier before use and confirm the use before using.

6. The shape and size of the installation

Please confirm the model and material of the quick connector, and specify the assembly shape and size corresponding to the piping characteristics. Please note that the size is related to the fluid flow.

The above is the introduction about the specifications and selection conditions of the quick connector. The quick coupling can be connected to any material of the pipe body, and it is an ideal pipe joint in shipbuilding, water supply and drainage and sewage plants, industrial processing pipelines, and other applications, and its uses are very wide in various fields. Therefore, we should have a certain understanding of it.
