When using a VCR connector, do not rotate the external threaded nut or body. Instead, fix the external threaded nut or body and rotate the internal threaded nut. So, do you know the inspection methods for VCR connectors after installation?
The inspection method for VCR connectors after installation is as follows:
If the VCR connector is not tightened properly during installation, there may be a risk of leakage. After installation, you can follow the following steps to check:
1. Check if the angle of the marking line on the VCR internal and external threaded nuts meets the installation angle standards (stainless steel/nickel gasket, 45 degrees; copper gasket, 90 degrees); Observe whether a gasket is installed in the test hole on the internally threaded nut. These inspection methods are simple and easy to implement, but they need to be marked during construction to reduce the trouble of reinstallation caused by subsequent leak testing failures.
2. Positive pressure holding test or vacuum helium leak detection check the leakage holes on the VCR connector to ensure that there is no leakage in the pipeline.
After passing the leakage test, important pipelines should be properly labeled, and VCR joint locking devices should be installed for pipelines with vibration to prevent vibration loosening.
The VCR connector has such good sealing performance, but in the actual installation process, if the correct installation operation method is not used, it may cause the connector to be damaged and leak, or even the connector to be directly scrapped.
