1、流体的种类、温度,请选定适合流体的种类、温度的本体材质与密封材质的快速接头。根据流体,适合的本体材质、密封材质是不同的。例如,快速接头通的介质是水,则选黄铜的或者不锈钢制的。

  2、快速接头的使用环境,请选定适合使用环境的构造、材质的快速接头。结合使用环境的湿度条件、尘埃的状况,以及容易腐蚀等使用环境,来考虑选定快速接头的种类、本体材质、密封材质。

  3、液体的压力,请选定适合流体压力的耐压性能的快速接头。流体的压力也是选定快速接头的关键。油压用的快速接头是5.0Mpa(51kgf/cm²)-68.6Mpa(700kgf/cm²)之间形成系列化,相应于耐压特性,快速接头的构造也是不同的。

  4、安装的形状、尺寸。请在确定最后的形状、尺寸后订购产品。请确定快速接头的型号和材质,并指定相应于配管特性的装配形状及尺寸。请注意尺寸是与流体流量相关连的。

  5、自动开关阀门的构造,请选定适合配管用途的阀门构造的快速接头。对于阀门的构造,有两路开关型、单程开关型及两路开放型。由于在分离时除两路开关型以外,有流体从配管内流出。所以请注意。

  6、确认选择的快速接头连接螺纹要一致。在有不同品牌产品的使用过程中,最好是同一品牌的阴头和阳头配合使用,如果一定要交叉使用,最好使用前咨询产品供应方的技术人员,确认好之后再行使用。

1. For the type and temperature of the fluid, please select the quick connector of the body material and the sealing material suitable for the type and temperature of the fluid. According to the fluid, the suitable body material and sealing material are different. For example, if the medium of quick connector is water, choose brass or stainless steel.

2. For the use environment of quick connector, please select the quick connector suitable for the structure and material of the use environment. The type, material and sealing material of the quick connector shall be selected according to the humidity, dust and corrosive environment.

3. For the pressure of liquid, please select the fast connector with pressure resistance suitable for the pressure of liquid. The pressure of the fluid is also the key to the selection of the quick connector. The quick connector for oil pressure is a series of 5.0mpa (51kgf / cm2) - 68.6mpa (700kgf / cm2). Corresponding to the pressure resistance characteristics, the structure of the quick connector is also different.

4. Installation shape and size. Please order the product after confirming the final shape and size. Determine the model and material of the quick connector, and specify the assembly shape and size corresponding to the piping properties. Note that dimensions are related to fluid flow.

5. For the structure of automatic switch valve, please select the quick connector of valve structure suitable for piping. For valve construction, there are two-way switch type, one-way switch type and two-way open type. In addition to the two-way switch type, there is fluid flowing out of the pipe during separation. So please pay attention.

6. Confirm that the selected connecting thread of quick connector should be consistent. In the process of using products with different brands, it is better to use the same brand's female and male head together. If cross use is necessary, it is better to consult the technical personnel of the product supplier before use, and use after confirmation
